feat(core,storage): add Work Board Phase 0 contract and store

[somewan820]

Work Board Phase 0

This PR implements the maintainer-approved Phase 0 Work Board contract (see the 7-point review and accepted revision in #2560).

Key points:

• durable Work Board items with no total item cap
• bounded pagination (default 50, max 100)
• explicit todo/in_progress/done lifecycle
• strict provenance union (manual / main_conversation / side_conversation)
• SQLite scope/project invariant
• semantic patch mutation semantics
• monotonic revision + optional expectedRevision CAS
• serialized transactional writes (BEGIN IMMEDIATE)
• archive-before-delete semantics
• active-row partial indexes so default list queries stay bounded under archive-heavy data
• schema 8 -> 9 additive migration
• fail-closed corruption detection

Maintainer-confirmed deferrals (liugddx, #2560):

• linkedSessions moves to Phase 3; Phase 0 rejects the field in create input and stored records
• linked-session projection is deferred to Phase 3; it will be implemented beside the canonical Runtime Host / Desktop continuity adapter against SessionContinuitySnapshot / TurnSnapshot

Intentionally deferred:

• Task Ledger integration
• Runtime Host integration
• model-visible Work Board tools
• recovery/graph state
• resultRefs
• automatic completion

Verification

• core + storage focused tests pass (30 tests)
• @maka/core and @maka/storage build/typecheck
• Biome clean
• migration: v0.1.6 fixture + exact v8 DDL -> real 8->9 path; old schema objects retained; partial indexes present
• archive-heavy list queries covered by EXPLAIN QUERY PLAN regression test against the production query builder
• cross-process CAS covered by a worker-thread test (one winner, one operation_conflict)

Checklist

• Phase 0 contract matches the maintainer-approved scope and deferrals
• Migration is additive (8 -> 9) with no user-data DROP
• Tests updated and passing
• Docs and PR description current

Thanks for defining the Work Board authority boundary before adding UI or Runtime integration.

Before getting into the implementation details, I think the product scope should be reconciled with the more recent decision in #2290. That discussion deliberately reduced the Session Task Ledger to a narrow Session-local Todo snapshot: no stable item identity, per-item CRUD, hierarchy, evidence, pagination, or workflow UI.

I understand that #2560 describes a different owner: Work Board items are user-owned, cross-Session deferred intentions, while SessionTodo is a model-authored progress snapshot. I am not suggesting that Work Board should reuse SessionTodo or the Task Ledger.

The remaining question is whether this distinct product surface needs a full Work Board domain yet. This PR introduces another durable task-like entity with stable IDs, per-item mutations, scopes, provenance variants, a state machine, archive/delete behavior, pagination, revisions, and future Session links—before there is a UI or production caller. That appears to reintroduce much of the product and maintenance complexity that #2290 has just removed from the existing task system.

Could we first establish why a minimal user-owned Todo list is insufficient for the actual problem of “remember this for later without interrupting the current Session”? A small vertical slice—capture, list, complete, and delete, with optional project/source context—would validate the user need without fixing the larger Board contract in schema v1. Session linking and execution projection could then be added when “start as task” has a real consumer.

If the broader Work Board scope remains intentional after that reconciliation, I found three implementation issues that seem worth resolving before the Phase 0 schema is published:

1. The revision check is outside the SQLite write transaction. Two processes can both read revision 1, both pass expectedRevision: 1, both write revision 2, and the later write silently overwrites the earlier semantic patch. Please make the read/check/write sequence one BEGIN IMMEDIATE transaction, or use conditional UPDATE/DELETE ... WHERE revision = ? statements and treat zero affected rows as a conflict.

2. The linked-session projector validates a new DTO rather than the canonical SessionContinuitySnapshot. It also uses Core TurnStatus, which rejects valid continuity states such as waiting_for_user and cancelled. Since there is no production consumer yet, the simplest option may be to defer this projector until it can live beside the real Runtime Host/Desktop continuity adapter instead of introducing a parallel contract now.

3. The new index does not satisfy the list ordering. The default unscoped query performs a full-table scan and temporary sort, while scoped queries still require a temporary sort for the final key because item_id has the opposite direction. Since the contract intentionally has no total item cap, pagination currently bounds returned rows but not query work. Please align the indexes with the actual scoped/unscoped query shapes before schema v9 is released.

The focused tests and current CI are green. I would also replace the fresh-database “migration” test with a real schema-8 upgrade fixture, but I see that as a verification improvement rather than a separate production finding.

感谢你在增加 UI 或 Runtime 集成前，先明确 Work Board 的权威边界。

在讨论具体实现前，我认为这里的产品范围需要先与 #2290 中较新的决定重新对齐。该讨论刚刚把 Session Task Ledger 明确收缩为一个很窄的 Session-local Todo 快照：没有稳定的事项身份、逐项 CRUD、层级、证据、分页或 workflow UI。

我理解 #2560 定义的是另一个 owner：Work Board 是用户拥有的、跨 Session 的暂缓事项；SessionTodo 则是模型写入的进度快照。我并不是建议 Work Board 复用 SessionTodo 或 Task Ledger。

真正需要确认的是：这个独立的产品界面现在是否已经需要一套完整的 Work Board 领域模型。本 PR 在还没有 UI 和生产调用方时，就引入了另一个持久化的 task-like 实体，包括稳定 ID、逐项 mutation、scope、多种 provenance、状态机、归档/删除、分页、revision，以及未来的 Session 关联。这似乎重新引入了 #2290 刚从现有任务系统中删除的大量产品与维护复杂度。

我们是否应该先说明：对于“记住这个后续事项，但不要打断当前 Session”这一真实问题，为什么一个最小的、用户拥有的 Todo 列表还不够？先交付一条较小的纵向链路——保存、列出、完成和删除，并按需携带项目或来源上下文——就可以验证用户需求，而不必现在把更大的 Board contract 固化进 schema v1。等“启动为任务”出现真实消费者时，再增加 Session 关联和执行状态投影也不迟。

如果重新对齐后，完整的 Work Board 范围仍然是有意保留的，我还发现三个建议在发布 Phase 0 schema 前解决的实现问题：

1. revision 检查发生在 SQLite 写事务之外。两个进程可以同时读到 revision 1，都通过 expectedRevision: 1，然后分别写入 revision 2；后写入的 semantic patch 会静默覆盖前一次修改。建议把读取、检查和写入放进同一个 BEGIN IMMEDIATE 事务，或者使用带 WHERE revision = ? 条件的 UPDATE/DELETE，并将影响行数为零视为冲突。

2. linked-session projector 校验的是一套新定义的 DTO，而不是权威的 SessionContinuitySnapshot。它还使用了 Core TurnStatus，因此会拒绝 waiting_for_user、cancelled 等合法的 continuity 状态。当前还没有生产调用方，最简单的方案可能是先推迟这个 projector，等真实的 Runtime Host/Desktop continuity adapter 出现时再贴近实际 owner 实现，避免现在引入一份平行契约。

3. 新增索引不能满足 list 的实际排序。默认的无 scope 查询会全表扫描并临时排序；scoped 查询也会因为 item_id 的索引方向与查询相反，对最后一个排序键进行临时排序。由于契约明确不设置事项总量上限，目前分页只限制了返回行数，并没有限制每页查询的工作量。建议在 schema v9 发布前，让索引与 scoped/unscoped 查询的真实形态一致。

Focused tests 和当前 CI 均已通过。我还建议把“从空数据库创建 v9”的 migration 测试替换成真实的 schema 8 升级 fixture，不过这属于验证改进，不是独立的生产 finding。

AI-assisted review disclosure: Codex and Claude Opus were used to inspect the change and challenge the findings. I reproduced and adjudicated the issues above against the current source and own this review.

[somewan820]

Thanks for the review. I have verified all three implementation findings and fixed them in 476eb218b:

1. Revision CAS — update / archive / unarchive / remove now run the full read → revision check → write sequence inside one BEGIN IMMEDIATE transaction. The in-process write queue is retained for process-local serialization; the transaction closes the cross-process race. I confirmed the shared transaction helper flattens the nested #writeItem call, so there is no premature commit.

2. Linked-session projection — work-board-session-projection.ts (module, test, and package export) is removed. It was a parallel DTO validated with Core TurnStatus, which cannot represent waiting_for_user / cancelled from the canonical continuity contract. With no production consumer in Phase 0, I agree the projector should wait until Phase 3 and live beside the real Runtime Host / Desktop continuity adapter.

3. Indexes — schema v9 now ships (scope_kind, project_id, updated_at DESC, item_id DESC) and (updated_at DESC, item_id DESC). I verified against populated data with EXPLAIN QUERY PLAN: the default unscoped query, scoped queries (project and inbox), and both cursor forms use the indexes and no longer perform a full-table scan or temporary sort.

The migration test now builds a real schema-8 database from the released v0.1.6 operational-state fixture plus the exact v8 workflow DDL, then runs the actual 8→9 migration path and checks that the board table exists and the old schema objects remain.

On the product-scope question, I would like to separate PR fidelity from contract re-scoping:

• Fidelity to product(desktop): capture deferred work in a project-aware Work Board #2560: every semantic in this PR maps to the maintainer-approved Phase 0 contract from liugddx's review (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)) and the accepted revision (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)). Most of the surface you listed is load-bearing for that contract: pagination and archive/delete replaced the total-item cap the maintainer removed; revision/CAS was explicitly requested for concurrent renderer writes; provenance variants are required for side-chat capture to survive fork deletion; stable identity is the reference point Phase 3 "start as task" will need.

• RFC: Radically slim the Session Task Ledger #2290's Option 2 governs SessionTodo, not Work Board: the explicit-absent list in RFC: Radically slim the Session Task Ledger #2290 applies to the model-authored, Session-local progress snapshot. Work Board is a different owner (user-owned, cross-Session). Your own acceptance comment in RFC: Radically slim the Session Task Ledger #2290 states that product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 may proceed independently and should not become a P3 integration dependency of RFC: Radically slim the Session Task Ledger #2290 (RFC: Radically slim the Session Task Ledger #2290 (comment)).

The one item I agree has no Phase 0 consumer today is linkedSessions: the field exists in the schema, but Phase 0 has no mutation path that writes it and no UI or runtime caller reads it; Phase 3 "start as task" is the intended consumer. Rather than removing a maintainer-approved field unilaterally, I would like a decision.

@liugddx, could you please confirm:

(a) Does Phase 0 remain the approved contract after #2290 Option 2, or should it be re-scoped to capture / list / complete / delete with optional project and source context?

(b) Should linkedSessions stay in schema v1, or move to Phase 3 via a future additive migration?

(c) Is the linked-session projection formally deferred (removed from the Phase 0 deliverables), or do you want it implemented in Phase 0 against the canonical SessionContinuitySnapshot / TurnSnapshot?

I will not push further commits until these are resolved.

简体中文

感谢 review。三个实现问题我都已核验并在 476eb218b 修复：

1. Revision CAS：update / archive / unarchive / remove 现在把“读取 → revision 校验 → 写入”完整放进同一个 BEGIN IMMEDIATE 事务。进程内 write queue 保留用于单进程串行化；事务关闭跨进程竞争窗口。我已确认共享事务助手会扁平化嵌套的 #writeItem 调用，不会提前提交。

2. Linked-session projection：work-board-session-projection.ts（模块、测试、package export）已删除。它是一套平行 DTO，用 Core TurnStatus 校验，无法表达 canonical continuity 中的 waiting_for_user / cancelled。Phase 0 没有生产消费者，我同意推迟到 Phase 3，并放到真实 Runtime Host / Desktop continuity adapter 旁边实现。

3. 索引：schema v9 现在包含 (scope_kind, project_id, updated_at DESC, item_id DESC) 和 (updated_at DESC, item_id DESC)。我用真实填充数据跑了 EXPLAIN QUERY PLAN：默认 unscoped 查询、scoped 查询（project 与 inbox）以及两种 cursor 形态都使用索引，不再全表扫描或临时排序。

Migration 测试现在用发布的 v0.1.6 operational-state fixture + 精确的 v8 workflow DDL 构造真实 schema-8 库，走完整 8→9 迁移路径，并断言新表存在、旧 schema 对象保留。

关于产品范围问题，我想把“PR 是否忠实”和“契约是否要重新收缩”分开：

• 对 product(desktop): capture deferred work in a project-aware Work Board #2560 的忠实度：本 PR 的每个 semantic 都能对应 liugddx 的 maintainer review（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294753604）和已接受的修订版（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294956443）。你点名的多数复杂度都是该契约的承重结构：分页和 archive/delete 替代了 maintainer 移除的总上限；revision/CAS 是并发 renderer 写入的明确要求；provenance variants 是 side-chat 捕获在 fork 删除后仍可追溯的验收条件；stable identity 是 Phase 3 “start as task” 需要的引用点。

• RFC: Radically slim the Session Task Ledger #2290 Option 2 约束的是 SessionTodo，不是 Work Board：RFC: Radically slim the Session Task Ledger #2290 的 explicitly-absent 列表针对 model-authored、Session-local 的进度快照。Work Board 是不同的 owner（user-owned、cross-Session）。你在 RFC: Radically slim the Session Task Ledger #2290 的接受评论里也明确写了 product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 可以独立推进，不应成为 RFC: Radically slim the Session Task Ledger #2290 的 P3 集成依赖（https://github.com/maka-agent/maka-agent/issues/2290#issuecomment-5298957426）。

我唯一同意“Phase 0 没有消费者”的是 linkedSessions：字段在 schema 里，但 Phase 0 没有任何 mutation 路径写入它，也没有 UI 或 runtime 调用方读取；Phase 3 “start as task” 才是消费者。与其单方面删除 maintainer 已批准的字段，我希望得到一个明确决定。

@liugddx 能否确认：

(a) #2290 Option 2 之后，Phase 0 是否仍然以已批准契约为准，还是收缩为 capture / list / complete / delete + 可选的 project/source context？

(b) linkedSessions 留在 schema v1，还是移到 Phase 3（未来 additive migration）？

(c) linked-session projection 是否正式推迟（从 Phase 0 交付物移除），还是要求在 Phase 0 基于 canonical SessionContinuitySnapshot / TurnSnapshot 实现？

在得到答复前我不会再 push 新 commit。

[liugddx]

Thanks for addressing Astro-Han's review carefully. I rechecked the updated implementation against the approved #2560 Phase 0 contract and the later #2290 Option 2 boundary.

My maintainer decisions are:

1. Phase 0 remains an independently approved Work Board contract.#2290 Option 2 narrows the model-authored, Session-local SessionTodo; it does not re-scope the user-owned, cross-Session Work Board into the same domain. The broader Phase 0 contract therefore does not need to be reduced to a generic Todo list solely because of #2290.
2. Move linkedSessions to Phase 3. It has no Phase 0 consumer, and it is already exposed as writable input through CreateWorkBoardItemInput and persisted by the create normalizer, so it is not merely a harmless reserved field. An additive migration when “start as task” has a real caller is the smaller and safer compatibility commitment.
3. The linked-session projection is formally deferred to Phase 3. Removing the parallel DTO was correct. Implement it beside the real Runtime Host/Desktop continuity adapter against canonical SessionContinuitySnapshot / TurnSnapshot facts when the consumer exists.

The CAS fix is correct: the read, revision check, and write now share one BEGIN IMMEDIATE transaction. The schema-8 upgrade fixture is also a meaningful improvement.

One implementation issue remains before merge: the index fix removes the temporary sort but does not bound filtering work for the default query. list() adds archived = 0, while neither ordering index contains archived. With an unbounded number of archived rows and few active rows, SQLite may still walk most of the ordering index to produce one active page. EXPLAIN QUERY PLAN reporting an index scan and no temporary B-tree does not disprove that scan cost.

Please add active-row partial indexes for both unscoped and scoped query shapes (or an equivalent design), and cover the archive-heavy case. After removing linkedSessions from the Phase 0 contract/store/tests and closing this remaining query-cost hole, the PR will match the approved authority boundary and be ready for another pass.

简体中文

感谢你认真处理 Astro-Han 的评审。我重新对照了已批准的 #2560 Phase 0 契约和后续 #2290 Option 2 的权威边界。

我的 maintainer 决策如下：

1. Phase 0 继续作为独立批准的 Work Board 契约推进。#2290 Option 2 收缩的是模型写入、Session-local 的 SessionTodo，并没有把用户拥有、跨 Session 的 Work Board 收缩进同一个领域。因此，不能仅因为 #2290 就把完整 Phase 0 再缩成普通 Todo 列表。
2. linkedSessions 移到 Phase 3。 Phase 0 没有消费者，而且它已经通过 CreateWorkBoardItemInput 暴露为可写输入，并由 create normalizer 持久化，所以它并不是一个无害的预留字段。等“启动为任务”出现真实调用方时，通过增量迁移增加，是更小、更安全的兼容性承诺。
3. linked-session projection 正式推迟到 Phase 3。 删除平行 DTO 是正确的。等真实消费者出现时，再放到 Runtime Host/Desktop continuity adapter 旁，基于规范的 SessionContinuitySnapshot / TurnSnapshot 事实实现。

CAS 修复成立：读取、revision 校验和写入现在位于同一个 BEGIN IMMEDIATE 事务中。真实 schema-8 升级 fixture 也是有意义的改进。

合并前还剩一个实现问题：索引修复消除了临时排序，但没有限制默认查询的过滤工作量。list() 会添加 archived = 0，但两个排序索引都不包含 archived。当归档记录无上限、活动记录很少时，SQLite 为返回一页活动事项仍可能遍历排序索引中的大多数记录。EXPLAIN QUERY PLAN 显示使用索引且没有临时 B-tree，并不能证明扫描成本受限。

请为 scoped 和 unscoped 的活动项查询增加 partial indexes（或等价设计），并覆盖“绝大多数记录已归档”的情况。删除 Phase 0 contract/store/tests 中的 linkedSessions，并补齐这个查询成本缺口后，本 PR 就能符合已批准的权威边界，可以进入下一轮评审。

📝 Walkthrough

Summary

• Problem solved

  • Adds the Phase 0 Work Board contract and durable SQLite storage.
  • Supports validated item creation, updates, listing, archiving, restoring, and removal.
  • Adds bounded cursor pagination, provenance checks, lifecycle invariants, semantic patches, and revision-based optimistic concurrency.
  • Detects corrupt records and rejects invalid scope, project, revision, timestamp, and archive data.

• Source of truth

  • Extends the existing packages/core contract and packages/storage SQLite workflow schema.
  • Does not create a parallel linked-session path. linkedSessions and linked-session projection remain deferred to Phase 3.

• Implementation scope

  • Provides the smallest coherent Phase 0 solution.
  • BEGIN IMMEDIATE transactions and the process-local write queue are necessary for serialized mutations and revision checks.
  • Schema migration 8→9 and active, scoped, cursor, and archive indexes support compatibility and query performance.

• Simplification

  • The removed linked-session projection does not reduce Phase 0 behavior or regression coverage.
  • Task Ledger, Runtime Host, model-visible tools, recovery state, result references, and automatic completion remain outside this change.
  • No further deletion or simplification is apparent without weakening behavior or regression coverage.

• Risks and validation

  • Main risks include migration compatibility, concurrent revision conflicts, pagination correctness, SQLite constraint enforcement, timestamp ordering, cursor scope binding, and corrupt-record detection.
  • Tests cover contract behavior, storage operations, worker-thread and cross-process CAS races, pagination, query plans, corruption, constraints, migration, and backup/restore.
  • Reported validation includes passing focused tests, successful builds and typechecks for both packages, and clean Biome checks.
  • Required-check status remains unverified because no direct repository check result is available.

Review-relevant risks

• The PR changes public packages/core and packages/storage exports and adds a durable SQLite schema migration. These are public-contract and release-affecting changes. Material changes in these areas require independent human review under repository policy.
• The PR changes persisted data behavior, including archive-before-delete enforcement, scope/project constraints, migrations, and corruption handling. These changes can affect user data and operational recovery. Material changes in these areas require independent human review under repository policy.
• No security, licensing, or governance effect was identified in the current diff.
• The person performing the merge reviews the final diff. A maintainer makes the final determination.

Thanks for the maintainer decisions. I've applied them in 833481e64:

• linkedSessions is removed from the Phase 0 contract, create input, store, and tests. The Phase 0 normalizer and decoder now reject the field (fail-closed), and the contract doc records it as a Phase 3 addition.
• The linked-session projection stays deferred to Phase 3, documented in the contract and the PR description.
• Active-row partial indexes were added for both default query shapes: workflow_work_board_items_active_order and workflow_work_board_items_active_scope_order (both WHERE archived = 0). The existing full ordering indexes remain for includeArchived queries.
• Archive-heavy coverage: the new storage test creates 120 archived + 6 active items, asserts list behavior, and verifies via EXPLAIN QUERY PLAN that default unscoped and scoped queries use the partial indexes without a temporary sort. The migration test also asserts both partial indexes exist after the 8→9 upgrade.

Verification: core + storage focused tests pass (26 tests), both packages build/typecheck, Biome is clean.

The PR is now ready for review. Let me know if you'd like any further adjustments.

感谢 maintainer 的决定。我已在 833481e64 全部落地：

• linkedSessions 已从 Phase 0 契约、create input、store 和测试中移除；Phase 0 的 normalizer 和 decoder 现在会拒绝该字段（fail-closed），契约文档记录为 Phase 3 加入。
• linked-session projection 保持推迟到 Phase 3，已写入契约文档和 PR description。
• 为两种默认查询形态新增 active-row partial index：workflow_work_board_items_active_order 和 workflow_work_board_items_active_scope_order（均为 WHERE archived = 0）；原有全量排序索引保留给 includeArchived 查询。
• Archive-heavy 覆盖：新增 storage 测试构造 120 条 archived + 6 条 active，断言 list 行为，并用 EXPLAIN QUERY PLAN 验证默认 unscoped/scoped 查询使用 partial index、无临时排序；migration 测试同时断言 8→9 升级后两个 partial index 存在。

验证：core + storage focused tests 全部通过（26 个），两个包 build/typecheck 通过，Biome 干净。

A corrupt row can never be deleted.

remove calls #requireItem, which decodes the row and throws corrupt_record when record_json is unparseable or disagrees with the indexed columns. The fail-closed read is correct, but it also blocks the only removal path. A user who hits a corrupt item cannot repair the board.

Add a repair path. One option is to allow deletion when expectedRevision matches the indexed revision column, without decoding record_json.

The cursor does not bind to the query filters.

encodeCursor stores only updatedAt and itemId. A cursor returned by an inbox-scoped page decodes successfully and applies without complaint to a project-scoped query or to an includeArchived: true query. The caller then receives a page that looks coherent but silently starts from an unrelated position in a different result set.

Include a filter fingerprint in the cursor payload, and reject a cursor whose fingerprint does not match the current query.

Bind the query-plan assertions to the store's own SQL.

The test hand-writes the list SQL. The store builds its list SQL internally. The assertions therefore prove only that the indexes serve this copy of the query. If the store query later changes its filter shape, ORDER BY, or limit, this test stays green while the production path falls back to a scan or a temp sort.

Export the query text (or a small explainListPlan helper) from work-board-store.ts and assert the plan for that exact string.

packages/core/src/work-board.ts:494

• Unarchive can currently decrease updatedAt if now is earlier than the stored updatedAt (e.g. wall clock skew). Because list ordering/pagination uses updatedAt, clamp this to keep timestamps monotonic (see e.g. sqlite-long-term-memory-store.ts:953).

 item: {
...activeFields,
archived: false,
updatedAt: now,
revision: item.revision + 1,
},

packages/core/src/work-board.ts:476

• Archive timestamps should be monotonic even if the wall clock moves backwards; otherwise an archive mutation can decrease updatedAt and break ordering/pagination. Consider clamping both archivedAt and updatedAt to at least the current item.updatedAt (consistent with other storage authorities).

 ...item,
archived: true,
archivedAt: now,
updatedAt: now,
revision: item.revision + 1,

packages/core/src/work-board.ts:460

• updatedAt can move backwards if the caller clock moves backwards (or a test/consumer passes an older now). Since list pagination/orders are keyed on updatedAt, a decreasing timestamp can cause incorrect ordering and cursor paging anomalies. Other stores clamp mutation timestamps to be monotonic (e.g. packages/storage/src/sqlite-long-term-memory-store.ts:953, packages/storage/src/managed-secret-store.ts:430-432).

Thanks for working through the earlier review rounds. I rechecked the current head, including the Core contract, SQLite lifecycle, migration, indexes, existing feedback, and focused store tests. The earlier CAS, linked-session projection, indexing, notes-patch, and migration-fixture findings are resolved.

I left three inline P2 comments covering exact-shape validation, monotonic mutation timestamps, and cursor/filter binding. None is a P0/P1, and I do not think this needs a broader redesign or PR split.

Two non-blocking test-truth follow-ups:

• The concurrent-mutation test uses one store, so it proves process-local serialization but would still pass without the cross-process BEGIN IMMEDIATE fix. I would keep it and name it accordingly; a worker/barrier test can cover cross-process CAS if that guarantee needs executable protection.
• The query-plan test is valuable, but it explains a handwritten copy of the list SQL rather than the SQL produced by list(). Sharing an internal query builder would keep the regression test tied to production without adding a public API.

I would keep the remaining contract, persistence, migration, archive, backup, and index tests; they cover distinct lifecycle seams rather than duplicating one another. Overall, the Work Board / SessionTodo authority split is sound, and the current Phase 0 scope is appropriately reduced.

中文对照

感谢持续处理前几轮 review。我重新检查了当前 head，包括 Core 契约、SQLite 生命周期、migration、索引、已有反馈和聚焦的 store 测试。之前的 CAS、linked-session projection、索引、notes patch 和 migration fixture 问题都已经解决。

我留下了三条 inline P2，分别涉及：

• 对 Work Board item 和 mutation input 进行 exact-shape 校验，避免未知字段被静默接受或在下一次写入时丢失；
• 在持久化事务中保持 mutation timestamp 单调，避免系统时钟回拨破坏 keyset pagination；
• 将 opaque cursor 与规范化后的 scope / includeArchived filters 绑定，避免跨结果集复用时静默漏项。

它们都不是 P0/P1，也不需要扩大成整体重构或拆分 PR。

另外有两项非阻塞的测试真实性建议：

• 当前并发 mutation 测试使用同一个 store，因此证明的是进程内串行化；即使没有跨进程 BEGIN IMMEDIATE 修复，它仍会通过。建议保留并让测试名称准确表达该范围；如需可执行地保护跨进程 CAS，再补 worker/barrier 测试。
• Query-plan 测试有价值，但它解释的是手写的 list SQL 副本，而不是 list() 实际生成的 SQL。共享内部 query builder 可以防止测试与生产查询逐渐漂移，同时不需要扩大公共 API。

其余 contract、persistence、migration、archive、backup 和 index 测试覆盖不同生命周期，不建议删除。总体而言，Work Board 与 SessionTodo 的权威边界正确，Phase 0 的当前范围也已经合理收缩。

AI-assisted review disclosure: Codex performed the primary lifecycle review and executable reproductions; three independent Codex reviewers covered contract scope, SQLite behavior, and test truthfulness; Claude performed a focused adversarial adjudication. The final findings were verified against the current PR head.

packages/storage/src/work-board-store.ts:358

• workBoardFilterFingerprint embeds the full projectId (max 160 chars) into filterFingerprint, but decodeCursor rejects fingerprints longer than 128 and the contract bounds cursor strings to 256 chars. For long project IDs this will produce an overlong cursor (and/or an undecodable cursor), causing pagination to fail after the first page with "cursor does not match the list filters".

• The cursor test now confirms that the second page has a different item ID.
• WorkBoardStore.list() and the query-plan test both use buildWorkBoardListStatement.
• The migration guard returns before migrateSqliteWorkflowDatabase on a current target schema. The DROP INDEX does not run on normal opens.

The remaining implementation findings are addressed. The index-rebuild finding remains withdrawn.

Learning: In `packages/storage/src/sqlite-workflow-schema.ts`, `migrateSqliteWorkflowDatabase` intentionally drops and recreates `workflow_work_board_items_scope_order`. An intermediate Phase 0 development build created the same index name with `item_id ASC` while registering schema version 9. `inspectAndMigrateOperationalState` only runs this migration when the schema registry or target schema does not match, so the drop executes only during migration. SQLite `CREATE INDEX IF NOT EXISTS` cannot replace the old same-name index definition.

packages/storage/src/tests/work-board-store.test.ts:352

• This test name says “cross-process”, but it uses Worker from node:worker_threads, which is cross-thread (same process) rather than cross-process. Either rename the test to match what it actually exercises, or switch to a child-process based worker if you truly need a cross-process regression.

Follow-up: I reviewed the current head (688051767). The requested Phase 0 scope changes, active-row partial indexes with archive-heavy coverage, and Astro-Han’s subsequent P2 findings are resolved. The remaining test-truth caveat is non-blocking. This PR is ready to merge.

[liugddx]

Approved. The current head satisfies the approved Phase 0 contract and resolves the outstanding review findings.

[Astro-Han]

Thanks for carrying the earlier review rounds through to a coherent Phase 0 boundary. I rechecked the current head after the maintainer approval, including the Core contract, SQLite lifecycle, migration/index paths, prior feedback, and focused tests.

The previous CAS transaction, linked-session deferral, active-row indexes, monotonic mutation timestamps, filter-bound cursors, and cursor-size fixes all hold. I found two remaining runtime-boundary gaps and left them inline:

• create/stored notes still accepts null even though that clear signal belongs only to update patches;
• unknown mutation-option keys can silently disable expectedRevision CAS.

Both are narrow exact-validation fixes at the existing owners. They do not call for reopening the product scope, redesigning the store, or splitting this PR.

Focused verification on 688051767:

• @maka/core build: passed
• @maka/storage build: passed
• Work Board storage test file: 17/17 passed
• visible GitHub checks: green

Once the two inline issues are addressed, this should only need a quick final pass.

Astro-Han — both P2 inline comments are fixed in cbf2dc64a (details in the threads):

• notes: null is now rejected in create input and stored records; null remains the explicit clear signal only in update patches.
• Mutation options are validated as an exact-shape object, so unknown keys like expectedRevison or extra fields throw invalid_input instead of silently disabling expectedRevision CAS.

Verification: core + storage focused tests pass (33 tests), both packages build/typecheck, Biome clean. liugddx already approved the prior head; the new commit only contains these two narrow validation fixes.

Could you take the quick final pass? If everything looks good, this PR is ready to merge. @liugddx — happy to merge once Astro-Han confirms.

简体中文

Astro-Han —— 两条 P2 代码评论已在 cbf2dc64a 修复（详见对应线程）：

• create input 和已存记录现在拒绝 notes: null；null 只保留为 update patch 的显式清除信号。
• mutation options 改为精确形状校验，expectedRevison 这类拼写错误或多余字段会直接 invalid_input，不会再静默关闭 expectedRevision CAS。

验证：core + storage focused tests 全部通过（33 个），两个包 build/typecheck 通过，Biome 干净。liugddx 已对前一版 head 表示 approve；本次新 commit 只包含这两处窄校验修复。

[Astro-Han]

Thanks for the quick follow-up. I rechecked the current head (cbf2dc64a) and both remaining P2 findings are resolved:

• create input and durable records now reject notes: null, while update patches retain null as the explicit clear signal;
• mutation options now fail closed on unknown keys, so a misspelled or extra field cannot silently disable expectedRevision CAS.

The regression tests exercise the real contract/store boundaries and verify that rejected mutation options leave the stored revision and state unchanged. I found no remaining P0–P3 issues.

The Phase 0 authority boundary remains intact: Core owns the item contract, Storage owns durable mutation and CAS, and no Runtime execution state or parallel authority has been introduced. The current solution is the smallest complete implementation of the approved scope; it does not need further restructuring or a PR split.

Verification on cbf2dc64a:

• @maka/core build and focused Work Board tests: 15/15 passed
• @maka/storage build and focused Work Board tests: 18/18 passed
• Biome formatting check on the four changed files: passed
• git diff --check: passed
• visible GitHub checks: green

感谢快速处理。我重新检查了当前 head（cbf2dc64a），最后两条 P2 都已解决：

• create input 和持久化记录现在拒绝 notes: null，同时 update patch 仍保留 null 作为显式清除信号；
• mutation options 现在会拒绝未知字段，因此拼错或多余字段不会再静默关闭 expectedRevision CAS。

回归测试覆盖了真实的契约和 store 边界，并验证 mutation options 被拒绝后，持久化 revision 和 state 都不会变化。目前没有剩余 P0–P3。

Phase 0 的权威边界保持清晰：Core 负责 item contract，Storage 负责持久化 mutation 与 CAS，没有引入 Runtime 执行状态副本或平行 authority。当前方案已经是已批准范围内的最小完整实现，不需要继续重构或拆分 PR。

当前 head 的 Core/Storage build 通过，聚焦测试分别为 15/15 与 18/18，Biome、git diff --check 和 GitHub checks 均通过，merge state 为 clean。

我这边 approve。

Work Board Phase 0

This PR implements the maintainer-approved Phase 0 Work Board contract (see the 7-point review and accepted revision in #2560).

Key points:

• durable Work Board items with no total item cap
• bounded pagination (default 50, max 100)
• explicit todo/in_progress/done lifecycle
• strict provenance union (manual / main_conversation / side_conversation)
• SQLite scope/project invariant
• semantic patch mutation semantics
• monotonic revision + optional expectedRevision CAS
• serialized transactional writes (BEGIN IMMEDIATE)
• archive-before-delete semantics
• active-row partial indexes so default list queries stay bounded under archive-heavy data
• schema 8 -> 9 additive migration
• fail-closed corruption detection

Maintainer-confirmed deferrals (liugddx, #2560):

• linkedSessions moves to Phase 3; Phase 0 rejects the field in create input and stored records
• linked-session projection is deferred to Phase 3; it will be implemented beside the canonical Runtime Host / Desktop continuity adapter against SessionContinuitySnapshot / TurnSnapshot

Intentionally deferred:

• Task Ledger integration
• Runtime Host integration
• model-visible Work Board tools
• recovery/graph state
• resultRefs
• automatic completion

Verification

• core + storage focused tests pass (30 tests)
• @maka/core and @maka/storage build/typecheck
• Biome clean
• migration: v0.1.6 fixture + exact v8 DDL -> real 8->9 path; old schema objects retained; partial indexes present
• archive-heavy list queries covered by EXPLAIN QUERY PLAN regression test against the production query builder
• cross-process CAS covered by a worker-thread test (one winner, one operation_conflict)

Checklist

• Phase 0 contract matches the maintainer-approved scope and deferrals
• Migration is additive (8 -> 9) with no user-data DROP
• Tests updated and passing
• Docs and PR description current

Thanks for defining the Work Board authority boundary before adding UI or Runtime integration.

Before getting into the implementation details, I think the product scope should be reconciled with the more recent decision in #2290. That discussion deliberately reduced the Session Task Ledger to a narrow Session-local Todo snapshot: no stable item identity, per-item CRUD, hierarchy, evidence, pagination, or workflow UI.

I understand that #2560 describes a different owner: Work Board items are user-owned, cross-Session deferred intentions, while SessionTodo is a model-authored progress snapshot. I am not suggesting that Work Board should reuse SessionTodo or the Task Ledger.

The remaining question is whether this distinct product surface needs a full Work Board domain yet. This PR introduces another durable task-like entity with stable IDs, per-item mutations, scopes, provenance variants, a state machine, archive/delete behavior, pagination, revisions, and future Session links—before there is a UI or production caller. That appears to reintroduce much of the product and maintenance complexity that #2290 has just removed from the existing task system.

Could we first establish why a minimal user-owned Todo list is insufficient for the actual problem of “remember this for later without interrupting the current Session”? A small vertical slice—capture, list, complete, and delete, with optional project/source context—would validate the user need without fixing the larger Board contract in schema v1. Session linking and execution projection could then be added when “start as task” has a real consumer.

If the broader Work Board scope remains intentional after that reconciliation, I found three implementation issues that seem worth resolving before the Phase 0 schema is published:

1. The revision check is outside the SQLite write transaction. Two processes can both read revision 1, both pass expectedRevision: 1, both write revision 2, and the later write silently overwrites the earlier semantic patch. Please make the read/check/write sequence one BEGIN IMMEDIATE transaction, or use conditional UPDATE/DELETE ... WHERE revision = ? statements and treat zero affected rows as a conflict.

2. The linked-session projector validates a new DTO rather than the canonical SessionContinuitySnapshot. It also uses Core TurnStatus, which rejects valid continuity states such as waiting_for_user and cancelled. Since there is no production consumer yet, the simplest option may be to defer this projector until it can live beside the real Runtime Host/Desktop continuity adapter instead of introducing a parallel contract now.

3. The new index does not satisfy the list ordering. The default unscoped query performs a full-table scan and temporary sort, while scoped queries still require a temporary sort for the final key because item_id has the opposite direction. Since the contract intentionally has no total item cap, pagination currently bounds returned rows but not query work. Please align the indexes with the actual scoped/unscoped query shapes before schema v9 is released.

The focused tests and current CI are green. I would also replace the fresh-database “migration” test with a real schema-8 upgrade fixture, but I see that as a verification improvement rather than a separate production finding.

感谢你在增加 UI 或 Runtime 集成前，先明确 Work Board 的权威边界。

在讨论具体实现前，我认为这里的产品范围需要先与 #2290 中较新的决定重新对齐。该讨论刚刚把 Session Task Ledger 明确收缩为一个很窄的 Session-local Todo 快照：没有稳定的事项身份、逐项 CRUD、层级、证据、分页或 workflow UI。

我理解 #2560 定义的是另一个 owner：Work Board 是用户拥有的、跨 Session 的暂缓事项；SessionTodo 则是模型写入的进度快照。我并不是建议 Work Board 复用 SessionTodo 或 Task Ledger。

真正需要确认的是：这个独立的产品界面现在是否已经需要一套完整的 Work Board 领域模型。本 PR 在还没有 UI 和生产调用方时，就引入了另一个持久化的 task-like 实体，包括稳定 ID、逐项 mutation、scope、多种 provenance、状态机、归档/删除、分页、revision，以及未来的 Session 关联。这似乎重新引入了 #2290 刚从现有任务系统中删除的大量产品与维护复杂度。

我们是否应该先说明：对于“记住这个后续事项，但不要打断当前 Session”这一真实问题，为什么一个最小的、用户拥有的 Todo 列表还不够？先交付一条较小的纵向链路——保存、列出、完成和删除，并按需携带项目或来源上下文——就可以验证用户需求，而不必现在把更大的 Board contract 固化进 schema v1。等“启动为任务”出现真实消费者时，再增加 Session 关联和执行状态投影也不迟。

如果重新对齐后，完整的 Work Board 范围仍然是有意保留的，我还发现三个建议在发布 Phase 0 schema 前解决的实现问题：

1. revision 检查发生在 SQLite 写事务之外。两个进程可以同时读到 revision 1，都通过 expectedRevision: 1，然后分别写入 revision 2；后写入的 semantic patch 会静默覆盖前一次修改。建议把读取、检查和写入放进同一个 BEGIN IMMEDIATE 事务，或者使用带 WHERE revision = ? 条件的 UPDATE/DELETE，并将影响行数为零视为冲突。

2. linked-session projector 校验的是一套新定义的 DTO，而不是权威的 SessionContinuitySnapshot。它还使用了 Core TurnStatus，因此会拒绝 waiting_for_user、cancelled 等合法的 continuity 状态。当前还没有生产调用方，最简单的方案可能是先推迟这个 projector，等真实的 Runtime Host/Desktop continuity adapter 出现时再贴近实际 owner 实现，避免现在引入一份平行契约。

3. 新增索引不能满足 list 的实际排序。默认的无 scope 查询会全表扫描并临时排序；scoped 查询也会因为 item_id 的索引方向与查询相反，对最后一个排序键进行临时排序。由于契约明确不设置事项总量上限，目前分页只限制了返回行数，并没有限制每页查询的工作量。建议在 schema v9 发布前，让索引与 scoped/unscoped 查询的真实形态一致。

Focused tests 和当前 CI 均已通过。我还建议把“从空数据库创建 v9”的 migration 测试替换成真实的 schema 8 升级 fixture，不过这属于验证改进，不是独立的生产 finding。

AI-assisted review disclosure: Codex and Claude Opus were used to inspect the change and challenge the findings. I reproduced and adjudicated the issues above against the current source and own this review.

[somewan820]

Thanks for the review. I have verified all three implementation findings and fixed them in 476eb218b:

1. Revision CAS — update / archive / unarchive / remove now run the full read → revision check → write sequence inside one BEGIN IMMEDIATE transaction. The in-process write queue is retained for process-local serialization; the transaction closes the cross-process race. I confirmed the shared transaction helper flattens the nested #writeItem call, so there is no premature commit.

2. Linked-session projection — work-board-session-projection.ts (module, test, and package export) is removed. It was a parallel DTO validated with Core TurnStatus, which cannot represent waiting_for_user / cancelled from the canonical continuity contract. With no production consumer in Phase 0, I agree the projector should wait until Phase 3 and live beside the real Runtime Host / Desktop continuity adapter.

3. Indexes — schema v9 now ships (scope_kind, project_id, updated_at DESC, item_id DESC) and (updated_at DESC, item_id DESC). I verified against populated data with EXPLAIN QUERY PLAN: the default unscoped query, scoped queries (project and inbox), and both cursor forms use the indexes and no longer perform a full-table scan or temporary sort.

The migration test now builds a real schema-8 database from the released v0.1.6 operational-state fixture plus the exact v8 workflow DDL, then runs the actual 8→9 migration path and checks that the board table exists and the old schema objects remain.

On the product-scope question, I would like to separate PR fidelity from contract re-scoping:

• Fidelity to product(desktop): capture deferred work in a project-aware Work Board #2560: every semantic in this PR maps to the maintainer-approved Phase 0 contract from liugddx's review (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)) and the accepted revision (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)). Most of the surface you listed is load-bearing for that contract: pagination and archive/delete replaced the total-item cap the maintainer removed; revision/CAS was explicitly requested for concurrent renderer writes; provenance variants are required for side-chat capture to survive fork deletion; stable identity is the reference point Phase 3 "start as task" will need.

• RFC: Radically slim the Session Task Ledger #2290's Option 2 governs SessionTodo, not Work Board: the explicit-absent list in RFC: Radically slim the Session Task Ledger #2290 applies to the model-authored, Session-local progress snapshot. Work Board is a different owner (user-owned, cross-Session). Your own acceptance comment in RFC: Radically slim the Session Task Ledger #2290 states that product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 may proceed independently and should not become a P3 integration dependency of RFC: Radically slim the Session Task Ledger #2290 (RFC: Radically slim the Session Task Ledger #2290 (comment)).

The one item I agree has no Phase 0 consumer today is linkedSessions: the field exists in the schema, but Phase 0 has no mutation path that writes it and no UI or runtime caller reads it; Phase 3 "start as task" is the intended consumer. Rather than removing a maintainer-approved field unilaterally, I would like a decision.

@liugddx, could you please confirm:

(a) Does Phase 0 remain the approved contract after #2290 Option 2, or should it be re-scoped to capture / list / complete / delete with optional project and source context?

(b) Should linkedSessions stay in schema v1, or move to Phase 3 via a future additive migration?

(c) Is the linked-session projection formally deferred (removed from the Phase 0 deliverables), or do you want it implemented in Phase 0 against the canonical SessionContinuitySnapshot / TurnSnapshot?

I will not push further commits until these are resolved.

简体中文

感谢 review。三个实现问题我都已核验并在 476eb218b 修复：

1. Revision CAS：update / archive / unarchive / remove 现在把“读取 → revision 校验 → 写入”完整放进同一个 BEGIN IMMEDIATE 事务。进程内 write queue 保留用于单进程串行化；事务关闭跨进程竞争窗口。我已确认共享事务助手会扁平化嵌套的 #writeItem 调用，不会提前提交。

2. Linked-session projection：work-board-session-projection.ts（模块、测试、package export）已删除。它是一套平行 DTO，用 Core TurnStatus 校验，无法表达 canonical continuity 中的 waiting_for_user / cancelled。Phase 0 没有生产消费者，我同意推迟到 Phase 3，并放到真实 Runtime Host / Desktop continuity adapter 旁边实现。

3. 索引：schema v9 现在包含 (scope_kind, project_id, updated_at DESC, item_id DESC) 和 (updated_at DESC, item_id DESC)。我用真实填充数据跑了 EXPLAIN QUERY PLAN：默认 unscoped 查询、scoped 查询（project 与 inbox）以及两种 cursor 形态都使用索引，不再全表扫描或临时排序。

Migration 测试现在用发布的 v0.1.6 operational-state fixture + 精确的 v8 workflow DDL 构造真实 schema-8 库，走完整 8→9 迁移路径，并断言新表存在、旧 schema 对象保留。

关于产品范围问题，我想把“PR 是否忠实”和“契约是否要重新收缩”分开：

• 对 product(desktop): capture deferred work in a project-aware Work Board #2560 的忠实度：本 PR 的每个 semantic 都能对应 liugddx 的 maintainer review（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294753604）和已接受的修订版（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294956443）。你点名的多数复杂度都是该契约的承重结构：分页和 archive/delete 替代了 maintainer 移除的总上限；revision/CAS 是并发 renderer 写入的明确要求；provenance variants 是 side-chat 捕获在 fork 删除后仍可追溯的验收条件；stable identity 是 Phase 3 “start as task” 需要的引用点。

• RFC: Radically slim the Session Task Ledger #2290 Option 2 约束的是 SessionTodo，不是 Work Board：RFC: Radically slim the Session Task Ledger #2290 的 explicitly-absent 列表针对 model-authored、Session-local 的进度快照。Work Board 是不同的 owner（user-owned、cross-Session）。你在 RFC: Radically slim the Session Task Ledger #2290 的接受评论里也明确写了 product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 可以独立推进，不应成为 RFC: Radically slim the Session Task Ledger #2290 的 P3 集成依赖（https://github.com/maka-agent/maka-agent/issues/2290#issuecomment-5298957426）。

我唯一同意“Phase 0 没有消费者”的是 linkedSessions：字段在 schema 里，但 Phase 0 没有任何 mutation 路径写入它，也没有 UI 或 runtime 调用方读取；Phase 3 “start as task” 才是消费者。与其单方面删除 maintainer 已批准的字段，我希望得到一个明确决定。

@liugddx 能否确认：

(a) #2290 Option 2 之后，Phase 0 是否仍然以已批准契约为准，还是收缩为 capture / list / complete / delete + 可选的 project/source context？

(b) linkedSessions 留在 schema v1，还是移到 Phase 3（未来 additive migration）？

(c) linked-session projection 是否正式推迟（从 Phase 0 交付物移除），还是要求在 Phase 0 基于 canonical SessionContinuitySnapshot / TurnSnapshot 实现？

在得到答复前我不会再 push 新 commit。

[liugddx]

Thanks for addressing Astro-Han's review carefully. I rechecked the updated implementation against the approved #2560 Phase 0 contract and the later #2290 Option 2 boundary.

My maintainer decisions are:

1. Phase 0 remains an independently approved Work Board contract.#2290 Option 2 narrows the model-authored, Session-local SessionTodo; it does not re-scope the user-owned, cross-Session Work Board into the same domain. The broader Phase 0 contract therefore does not need to be reduced to a generic Todo list solely because of #2290.
2. Move linkedSessions to Phase 3. It has no Phase 0 consumer, and it is already exposed as writable input through CreateWorkBoardItemInput and persisted by the create normalizer, so it is not merely a harmless reserved field. An additive migration when “start as task” has a real caller is the smaller and safer compatibility commitment.
3. The linked-session projection is formally deferred to Phase 3. Removing the parallel DTO was correct. Implement it beside the real Runtime Host/Desktop continuity adapter against canonical SessionContinuitySnapshot / TurnSnapshot facts when the consumer exists.

The CAS fix is correct: the read, revision check, and write now share one BEGIN IMMEDIATE transaction. The schema-8 upgrade fixture is also a meaningful improvement.

One implementation issue remains before merge: the index fix removes the temporary sort but does not bound filtering work for the default query. list() adds archived = 0, while neither ordering index contains archived. With an unbounded number of archived rows and few active rows, SQLite may still walk most of the ordering index to produce one active page. EXPLAIN QUERY PLAN reporting an index scan and no temporary B-tree does not disprove that scan cost.

Please add active-row partial indexes for both unscoped and scoped query shapes (or an equivalent design), and cover the archive-heavy case. After removing linkedSessions from the Phase 0 contract/store/tests and closing this remaining query-cost hole, the PR will match the approved authority boundary and be ready for another pass.

简体中文

感谢你认真处理 Astro-Han 的评审。我重新对照了已批准的 #2560 Phase 0 契约和后续 #2290 Option 2 的权威边界。

我的 maintainer 决策如下：

1. Phase 0 继续作为独立批准的 Work Board 契约推进。#2290 Option 2 收缩的是模型写入、Session-local 的 SessionTodo，并没有把用户拥有、跨 Session 的 Work Board 收缩进同一个领域。因此，不能仅因为 #2290 就把完整 Phase 0 再缩成普通 Todo 列表。
2. linkedSessions 移到 Phase 3。 Phase 0 没有消费者，而且它已经通过 CreateWorkBoardItemInput 暴露为可写输入，并由 create normalizer 持久化，所以它并不是一个无害的预留字段。等“启动为任务”出现真实调用方时，通过增量迁移增加，是更小、更安全的兼容性承诺。
3. linked-session projection 正式推迟到 Phase 3。 删除平行 DTO 是正确的。等真实消费者出现时，再放到 Runtime Host/Desktop continuity adapter 旁，基于规范的 SessionContinuitySnapshot / TurnSnapshot 事实实现。

CAS 修复成立：读取、revision 校验和写入现在位于同一个 BEGIN IMMEDIATE 事务中。真实 schema-8 升级 fixture 也是有意义的改进。

合并前还剩一个实现问题：索引修复消除了临时排序，但没有限制默认查询的过滤工作量。list() 会添加 archived = 0，但两个排序索引都不包含 archived。当归档记录无上限、活动记录很少时，SQLite 为返回一页活动事项仍可能遍历排序索引中的大多数记录。EXPLAIN QUERY PLAN 显示使用索引且没有临时 B-tree，并不能证明扫描成本受限。

请为 scoped 和 unscoped 的活动项查询增加 partial indexes（或等价设计），并覆盖“绝大多数记录已归档”的情况。删除 Phase 0 contract/store/tests 中的 linkedSessions，并补齐这个查询成本缺口后，本 PR 就能符合已批准的权威边界，可以进入下一轮评审。

📝 Walkthrough

Summary

• Problem solved

  • Adds the Phase 0 Work Board contract and durable SQLite storage.
  • Supports validated item creation, updates, listing, archiving, restoring, and removal.
  • Adds bounded cursor pagination, provenance checks, lifecycle invariants, semantic patches, and revision-based optimistic concurrency.
  • Detects corrupt records and rejects invalid scope, project, revision, timestamp, and archive data.

• Source of truth

  • Extends the existing packages/core contract and packages/storage SQLite workflow schema.
  • Does not create a parallel linked-session path. linkedSessions and linked-session projection remain deferred to Phase 3.

• Implementation scope

  • Provides the smallest coherent Phase 0 solution.
  • BEGIN IMMEDIATE transactions and the process-local write queue are necessary for serialized mutations and revision checks.
  • Schema migration 8→9 and active, scoped, cursor, and archive indexes support compatibility and query performance.

• Simplification

  • The removed linked-session projection does not reduce Phase 0 behavior or regression coverage.
  • Task Ledger, Runtime Host, model-visible tools, recovery state, result references, and automatic completion remain outside this change.
  • No further deletion or simplification is apparent without weakening behavior or regression coverage.

• Risks and validation

  • Main risks include migration compatibility, concurrent revision conflicts, pagination correctness, SQLite constraint enforcement, timestamp ordering, cursor scope binding, and corrupt-record detection.
  • Tests cover contract behavior, storage operations, worker-thread and cross-process CAS races, pagination, query plans, corruption, constraints, migration, and backup/restore.
  • Reported validation includes passing focused tests, successful builds and typechecks for both packages, and clean Biome checks.
  • Required-check status remains unverified because no direct repository check result is available.

Review-relevant risks

• The PR changes public packages/core and packages/storage exports and adds a durable SQLite schema migration. These are public-contract and release-affecting changes. Material changes in these areas require independent human review under repository policy.
• The PR changes persisted data behavior, including archive-before-delete enforcement, scope/project constraints, migrations, and corruption handling. These changes can affect user data and operational recovery. Material changes in these areas require independent human review under repository policy.
• No security, licensing, or governance effect was identified in the current diff.
• The person performing the merge reviews the final diff. A maintainer makes the final determination.

Thanks for the maintainer decisions. I've applied them in 833481e64:

• linkedSessions is removed from the Phase 0 contract, create input, store, and tests. The Phase 0 normalizer and decoder now reject the field (fail-closed), and the contract doc records it as a Phase 3 addition.
• The linked-session projection stays deferred to Phase 3, documented in the contract and the PR description.
• Active-row partial indexes were added for both default query shapes: workflow_work_board_items_active_order and workflow_work_board_items_active_scope_order (both WHERE archived = 0). The existing full ordering indexes remain for includeArchived queries.
• Archive-heavy coverage: the new storage test creates 120 archived + 6 active items, asserts list behavior, and verifies via EXPLAIN QUERY PLAN that default unscoped and scoped queries use the partial indexes without a temporary sort. The migration test also asserts both partial indexes exist after the 8→9 upgrade.

Verification: core + storage focused tests pass (26 tests), both packages build/typecheck, Biome is clean.

The PR is now ready for review. Let me know if you'd like any further adjustments.

感谢 maintainer 的决定。我已在 833481e64 全部落地：

• linkedSessions 已从 Phase 0 契约、create input、store 和测试中移除；Phase 0 的 normalizer 和 decoder 现在会拒绝该字段（fail-closed），契约文档记录为 Phase 3 加入。
• linked-session projection 保持推迟到 Phase 3，已写入契约文档和 PR description。
• 为两种默认查询形态新增 active-row partial index：workflow_work_board_items_active_order 和 workflow_work_board_items_active_scope_order（均为 WHERE archived = 0）；原有全量排序索引保留给 includeArchived 查询。
• Archive-heavy 覆盖：新增 storage 测试构造 120 条 archived + 6 条 active，断言 list 行为，并用 EXPLAIN QUERY PLAN 验证默认 unscoped/scoped 查询使用 partial index、无临时排序；migration 测试同时断言 8→9 升级后两个 partial index 存在。

验证：core + storage focused tests 全部通过（26 个），两个包 build/typecheck 通过，Biome 干净。

A corrupt row can never be deleted.

remove calls #requireItem, which decodes the row and throws corrupt_record when record_json is unparseable or disagrees with the indexed columns. The fail-closed read is correct, but it also blocks the only removal path. A user who hits a corrupt item cannot repair the board.

Add a repair path. One option is to allow deletion when expectedRevision matches the indexed revision column, without decoding record_json.

The cursor does not bind to the query filters.

encodeCursor stores only updatedAt and itemId. A cursor returned by an inbox-scoped page decodes successfully and applies without complaint to a project-scoped query or to an includeArchived: true query. The caller then receives a page that looks coherent but silently starts from an unrelated position in a different result set.

Bind the query-plan assertions to the store's own SQL.

The test hand-writes the list SQL. The store builds its list SQL internally. The assertions therefore prove only that the indexes serve this copy of the query. If the store query later changes its filter shape, ORDER BY, or limit, this test stays green while the production path falls back to a scan or a temp sort.

Export the query text (or a small explainListPlan helper) from work-board-store.ts and assert the plan for that exact string.

packages/core/src/work-board.ts:494

• Unarchive can currently decrease updatedAt if now is earlier than the stored updatedAt (e.g. wall clock skew). Because list ordering/pagination uses updatedAt, clamp this to keep timestamps monotonic (see e.g. sqlite-long-term-memory-store.ts:953).

 item: {
...activeFields,
archived: false,
updatedAt: now,
revision: item.revision + 1,
},

packages/core/src/work-board.ts:476

• Archive timestamps should be monotonic even if the wall clock moves backwards; otherwise an archive mutation can decrease updatedAt and break ordering/pagination. Consider clamping both archivedAt and updatedAt to at least the current item.updatedAt (consistent with other storage authorities).

 ...item,
archived: true,
archivedAt: now,
updatedAt: now,
revision: item.revision + 1,

packages/core/src/work-board.ts:460

• updatedAt can move backwards if the caller clock moves backwards (or a test/consumer passes an older now). Since list pagination/orders are keyed on updatedAt, a decreasing timestamp can cause incorrect ordering and cursor paging anomalies. Other stores clamp mutation timestamps to be monotonic (e.g. packages/storage/src/sqlite-long-term-memory-store.ts:953, packages/storage/src/managed-secret-store.ts:430-432).

Thanks for working through the earlier review rounds. I rechecked the current head, including the Core contract, SQLite lifecycle, migration, indexes, existing feedback, and focused store tests. The earlier CAS, linked-session projection, indexing, notes-patch, and migration-fixture findings are resolved.

I left three inline P2 comments covering exact-shape validation, monotonic mutation timestamps, and cursor/filter binding. None is a P0/P1, and I do not think this needs a broader redesign or PR split.

Two non-blocking test-truth follow-ups:

• The concurrent-mutation test uses one store, so it proves process-local serialization but would still pass without the cross-process BEGIN IMMEDIATE fix. I would keep it and name it accordingly; a worker/barrier test can cover cross-process CAS if that guarantee needs executable protection.
• The query-plan test is valuable, but it explains a handwritten copy of the list SQL rather than the SQL produced by list(). Sharing an internal query builder would keep the regression test tied to production without adding a public API.

I would keep the remaining contract, persistence, migration, archive, backup, and index tests; they cover distinct lifecycle seams rather than duplicating one another. Overall, the Work Board / SessionTodo authority split is sound, and the current Phase 0 scope is appropriately reduced.

中文对照

感谢持续处理前几轮 review。我重新检查了当前 head，包括 Core 契约、SQLite 生命周期、migration、索引、已有反馈和聚焦的 store 测试。之前的 CAS、linked-session projection、索引、notes patch 和 migration fixture 问题都已经解决。

我留下了三条 inline P2，分别涉及：

• 对 Work Board item 和 mutation input 进行 exact-shape 校验，避免未知字段被静默接受或在下一次写入时丢失；
• 在持久化事务中保持 mutation timestamp 单调，避免系统时钟回拨破坏 keyset pagination；
• 将 opaque cursor 与规范化后的 scope / includeArchived filters 绑定，避免跨结果集复用时静默漏项。

它们都不是 P0/P1，也不需要扩大成整体重构或拆分 PR。

另外有两项非阻塞的测试真实性建议：

• 当前并发 mutation 测试使用同一个 store，因此证明的是进程内串行化；即使没有跨进程 BEGIN IMMEDIATE 修复，它仍会通过。建议保留并让测试名称准确表达该范围；如需可执行地保护跨进程 CAS，再补 worker/barrier 测试。
• Query-plan 测试有价值，但它解释的是手写的 list SQL 副本，而不是 list() 实际生成的 SQL。共享内部 query builder 可以防止测试与生产查询逐渐漂移，同时不需要扩大公共 API。

其余 contract、persistence、migration、archive、backup 和 index 测试覆盖不同生命周期，不建议删除。总体而言，Work Board 与 SessionTodo 的权威边界正确，Phase 0 的当前范围也已经合理收缩。

AI-assisted review disclosure: Codex performed the primary lifecycle review and executable reproductions; three independent Codex reviewers covered contract scope, SQLite behavior, and test truthfulness; Claude performed a focused adversarial adjudication. The final findings were verified against the current PR head.

packages/storage/src/work-board-store.ts:358

• workBoardFilterFingerprint embeds the full projectId (max 160 chars) into filterFingerprint, but decodeCursor rejects fingerprints longer than 128 and the contract bounds cursor strings to 256 chars. For long project IDs this will produce an overlong cursor (and/or an undecodable cursor), causing pagination to fail after the first page with "cursor does not match the list filters".

• The cursor test now confirms that the second page has a different item ID.
• WorkBoardStore.list() and the query-plan test both use buildWorkBoardListStatement.
• The migration guard returns before migrateSqliteWorkflowDatabase on a current target schema. The DROP INDEX does not run on normal opens.

The remaining implementation findings are addressed. The index-rebuild finding remains withdrawn.

Learning: In `packages/storage/src/sqlite-workflow-schema.ts`, `migrateSqliteWorkflowDatabase` intentionally drops and recreates `workflow_work_board_items_scope_order`. An intermediate Phase 0 development build created the same index name with `item_id ASC` while registering schema version 9. `inspectAndMigrateOperationalState` only runs this migration when the schema registry or target schema does not match, so the drop executes only during migration. SQLite `CREATE INDEX IF NOT EXISTS` cannot replace the old same-name index definition.

• This test name says “cross-process”, but it uses Worker from node:worker_threads, which is cross-thread (same process) rather than cross-process. Either rename the test to match what it actually exercises, or switch to a child-process based worker if you truly need a cross-process regression.

Follow-up: I reviewed the current head (688051767). The requested Phase 0 scope changes, active-row partial indexes with archive-heavy coverage, and Astro-Han’s subsequent P2 findings are resolved. The remaining test-truth caveat is non-blocking. This PR is ready to merge.

[liugddx]

Approved. The current head satisfies the approved Phase 0 contract and resolves the outstanding review findings.

[Astro-Han]

Thanks for carrying the earlier review rounds through to a coherent Phase 0 boundary. I rechecked the current head after the maintainer approval, including the Core contract, SQLite lifecycle, migration/index paths, prior feedback, and focused tests.

The previous CAS transaction, linked-session deferral, active-row indexes, monotonic mutation timestamps, filter-bound cursors, and cursor-size fixes all hold. I found two remaining runtime-boundary gaps and left them inline:

• create/stored notes still accepts null even though that clear signal belongs only to update patches;
• unknown mutation-option keys can silently disable expectedRevision CAS.

Both are narrow exact-validation fixes at the existing owners. They do not call for reopening the product scope, redesigning the store, or splitting this PR.

Focused verification on 688051767:

• @maka/core build: passed
• @maka/storage build: passed
• Work Board storage test file: 17/17 passed
• visible GitHub checks: green

Once the two inline issues are addressed, this should only need a quick final pass.

Astro-Han — both P2 inline comments are fixed in cbf2dc64a (details in the threads):

• notes: null is now rejected in create input and stored records; null remains the explicit clear signal only in update patches.
• Mutation options are validated as an exact-shape object, so unknown keys like expectedRevison or extra fields throw invalid_input instead of silently disabling expectedRevision CAS.

Verification: core + storage focused tests pass (33 tests), both packages build/typecheck, Biome clean. liugddx already approved the prior head; the new commit only contains these two narrow validation fixes.

Could you take the quick final pass? If everything looks good, this PR is ready to merge. @liugddx — happy to merge once Astro-Han confirms.

简体中文

Astro-Han —— 两条 P2 代码评论已在 cbf2dc64a 修复（详见对应线程）：

• create input 和已存记录现在拒绝 notes: null；null 只保留为 update patch 的显式清除信号。
• mutation options 改为精确形状校验，expectedRevison 这类拼写错误或多余字段会直接 invalid_input，不会再静默关闭 expectedRevision CAS。

验证：core + storage focused tests 全部通过（33 个），两个包 build/typecheck 通过，Biome 干净。liugddx 已对前一版 head 表示 approve；本次新 commit 只包含这两处窄校验修复。

[Astro-Han]

Thanks for the quick follow-up. I rechecked the current head (cbf2dc64a) and both remaining P2 findings are resolved:

• create input and durable records now reject notes: null, while update patches retain null as the explicit clear signal;
• mutation options now fail closed on unknown keys, so a misspelled or extra field cannot silently disable expectedRevision CAS.

The regression tests exercise the real contract/store boundaries and verify that rejected mutation options leave the stored revision and state unchanged. I found no remaining P0–P3 issues.

The Phase 0 authority boundary remains intact: Core owns the item contract, Storage owns durable mutation and CAS, and no Runtime execution state or parallel authority has been introduced. The current solution is the smallest complete implementation of the approved scope; it does not need further restructuring or a PR split.

Verification on cbf2dc64a:

• @maka/core build and focused Work Board tests: 15/15 passed
• @maka/storage build and focused Work Board tests: 18/18 passed
• Biome formatting check on the four changed files: passed
• git diff --check: passed
• visible GitHub checks: green

感谢快速处理。我重新检查了当前 head（cbf2dc64a），最后两条 P2 都已解决：

• create input 和持久化记录现在拒绝 notes: null，同时 update patch 仍保留 null 作为显式清除信号；
• mutation options 现在会拒绝未知字段，因此拼错或多余字段不会再静默关闭 expectedRevision CAS。

回归测试覆盖了真实的契约和 store 边界，并验证 mutation options 被拒绝后，持久化 revision 和 state 都不会变化。目前没有剩余 P0–P3。

Phase 0 的权威边界保持清晰：Core 负责 item contract，Storage 负责持久化 mutation 与 CAS，没有引入 Runtime 执行状态副本或平行 authority。当前方案已经是已批准范围内的最小完整实现，不需要继续重构或拆分 PR。

当前 head 的 Core/Storage build 通过，聚焦测试分别为 15/15 与 18/18，Biome、git diff --check 和 GitHub checks 均通过，merge state 为 clean。

Work Board Phase 0

This PR implements the maintainer-approved Phase 0 Work Board contract (see the 7-point review and accepted revision in #2560).

Key points:

• durable Work Board items with no total item cap
• bounded pagination (default 50, max 100)
• explicit todo/in_progress/done lifecycle
• strict provenance union (manual / main_conversation / side_conversation)
• SQLite scope/project invariant
• semantic patch mutation semantics
• monotonic revision + optional expectedRevision CAS
• serialized transactional writes (BEGIN IMMEDIATE)
• archive-before-delete semantics
• active-row partial indexes so default list queries stay bounded under archive-heavy data
• schema 8 -> 9 additive migration
• fail-closed corruption detection

Maintainer-confirmed deferrals (liugddx, #2560):

• linkedSessions moves to Phase 3; Phase 0 rejects the field in create input and stored records
• linked-session projection is deferred to Phase 3; it will be implemented beside the canonical Runtime Host / Desktop continuity adapter against SessionContinuitySnapshot / TurnSnapshot

Intentionally deferred:

• Task Ledger integration
• Runtime Host integration
• model-visible Work Board tools
• recovery/graph state
• resultRefs
• automatic completion

Verification

• core + storage focused tests pass (30 tests)
• @maka/core and @maka/storage build/typecheck
• Biome clean
• migration: v0.1.6 fixture + exact v8 DDL -> real 8->9 path; old schema objects retained; partial indexes present
• archive-heavy list queries covered by EXPLAIN QUERY PLAN regression test against the production query builder
• cross-process CAS covered by a worker-thread test (one winner, one operation_conflict)

Checklist

• Phase 0 contract matches the maintainer-approved scope and deferrals
• Migration is additive (8 -> 9) with no user-data DROP
• Tests updated and passing
• Docs and PR description current

Refs #2560

[Astro-Han]

Thanks for defining the Work Board authority boundary before adding UI or Runtime integration.

Before getting into the implementation details, I think the product scope should be reconciled with the more recent decision in #2290. That discussion deliberately reduced the Session Task Ledger to a narrow Session-local Todo snapshot: no stable item identity, per-item CRUD, hierarchy, evidence, pagination, or workflow UI.

I understand that #2560 describes a different owner: Work Board items are user-owned, cross-Session deferred intentions, while SessionTodo is a model-authored progress snapshot. I am not suggesting that Work Board should reuse SessionTodo or the Task Ledger.

The remaining question is whether this distinct product surface needs a full Work Board domain yet. This PR introduces another durable task-like entity with stable IDs, per-item mutations, scopes, provenance variants, a state machine, archive/delete behavior, pagination, revisions, and future Session links—before there is a UI or production caller. That appears to reintroduce much of the product and maintenance complexity that #2290 has just removed from the existing task system.

Could we first establish why a minimal user-owned Todo list is insufficient for the actual problem of “remember this for later without interrupting the current Session”? A small vertical slice—capture, list, complete, and delete, with optional project/source context—would validate the user need without fixing the larger Board contract in schema v1. Session linking and execution projection could then be added when “start as task” has a real consumer.

If the broader Work Board scope remains intentional after that reconciliation, I found three implementation issues that seem worth resolving before the Phase 0 schema is published:

1. The revision check is outside the SQLite write transaction. Two processes can both read revision 1, both pass expectedRevision: 1, both write revision 2, and the later write silently overwrites the earlier semantic patch. Please make the read/check/write sequence one BEGIN IMMEDIATE transaction, or use conditional UPDATE/DELETE ... WHERE revision = ? statements and treat zero affected rows as a conflict.

2. The linked-session projector validates a new DTO rather than the canonical SessionContinuitySnapshot. It also uses Core TurnStatus, which rejects valid continuity states such as waiting_for_user and cancelled. Since there is no production consumer yet, the simplest option may be to defer this projector until it can live beside the real Runtime Host/Desktop continuity adapter instead of introducing a parallel contract now.

3. The new index does not satisfy the list ordering. The default unscoped query performs a full-table scan and temporary sort, while scoped queries still require a temporary sort for the final key because item_id has the opposite direction. Since the contract intentionally has no total item cap, pagination currently bounds returned rows but not query work. Please align the indexes with the actual scoped/unscoped query shapes before schema v9 is released.

The focused tests and current CI are green. I would also replace the fresh-database “migration” test with a real schema-8 upgrade fixture, but I see that as a verification improvement rather than a separate production finding.

感谢你在增加 UI 或 Runtime 集成前，先明确 Work Board 的权威边界。

在讨论具体实现前，我认为这里的产品范围需要先与 #2290 中较新的决定重新对齐。该讨论刚刚把 Session Task Ledger 明确收缩为一个很窄的 Session-local Todo 快照：没有稳定的事项身份、逐项 CRUD、层级、证据、分页或 workflow UI。

我理解 #2560 定义的是另一个 owner：Work Board 是用户拥有的、跨 Session 的暂缓事项；SessionTodo 则是模型写入的进度快照。我并不是建议 Work Board 复用 SessionTodo 或 Task Ledger。

真正需要确认的是：这个独立的产品界面现在是否已经需要一套完整的 Work Board 领域模型。本 PR 在还没有 UI 和生产调用方时，就引入了另一个持久化的 task-like 实体，包括稳定 ID、逐项 mutation、scope、多种 provenance、状态机、归档/删除、分页、revision，以及未来的 Session 关联。这似乎重新引入了 #2290 刚从现有任务系统中删除的大量产品与维护复杂度。

我们是否应该先说明：对于“记住这个后续事项，但不要打断当前 Session”这一真实问题，为什么一个最小的、用户拥有的 Todo 列表还不够？先交付一条较小的纵向链路——保存、列出、完成和删除，并按需携带项目或来源上下文——就可以验证用户需求，而不必现在把更大的 Board contract 固化进 schema v1。等“启动为任务”出现真实消费者时，再增加 Session 关联和执行状态投影也不迟。

如果重新对齐后，完整的 Work Board 范围仍然是有意保留的，我还发现三个建议在发布 Phase 0 schema 前解决的实现问题：

1. revision 检查发生在 SQLite 写事务之外。两个进程可以同时读到 revision 1，都通过 expectedRevision: 1，然后分别写入 revision 2；后写入的 semantic patch 会静默覆盖前一次修改。建议把读取、检查和写入放进同一个 BEGIN IMMEDIATE 事务，或者使用带 WHERE revision = ? 条件的 UPDATE/DELETE，并将影响行数为零视为冲突。

2. linked-session projector 校验的是一套新定义的 DTO，而不是权威的 SessionContinuitySnapshot。它还使用了 Core TurnStatus，因此会拒绝 waiting_for_user、cancelled 等合法的 continuity 状态。当前还没有生产调用方，最简单的方案可能是先推迟这个 projector，等真实的 Runtime Host/Desktop continuity adapter 出现时再贴近实际 owner 实现，避免现在引入一份平行契约。

3. 新增索引不能满足 list 的实际排序。默认的无 scope 查询会全表扫描并临时排序；scoped 查询也会因为 item_id 的索引方向与查询相反，对最后一个排序键进行临时排序。由于契约明确不设置事项总量上限，目前分页只限制了返回行数，并没有限制每页查询的工作量。建议在 schema v9 发布前，让索引与 scoped/unscoped 查询的真实形态一致。

Focused tests 和当前 CI 均已通过。我还建议把“从空数据库创建 v9”的 migration 测试替换成真实的 schema 8 升级 fixture，不过这属于验证改进，不是独立的生产 finding。

[somewan820]

Thanks for the review. I have verified all three implementation findings and fixed them in 476eb218b:

1. Revision CAS — update / archive / unarchive / remove now run the full read → revision check → write sequence inside one BEGIN IMMEDIATE transaction. The in-process write queue is retained for process-local serialization; the transaction closes the cross-process race. I confirmed the shared transaction helper flattens the nested #writeItem call, so there is no premature commit.

2. Linked-session projection — work-board-session-projection.ts (module, test, and package export) is removed. It was a parallel DTO validated with Core TurnStatus, which cannot represent waiting_for_user / cancelled from the canonical continuity contract. With no production consumer in Phase 0, I agree the projector should wait until Phase 3 and live beside the real Runtime Host / Desktop continuity adapter.

3. Indexes — schema v9 now ships (scope_kind, project_id, updated_at DESC, item_id DESC) and (updated_at DESC, item_id DESC). I verified against populated data with EXPLAIN QUERY PLAN: the default unscoped query, scoped queries (project and inbox), and both cursor forms use the indexes and no longer perform a full-table scan or temporary sort.

The migration test now builds a real schema-8 database from the released v0.1.6 operational-state fixture plus the exact v8 workflow DDL, then runs the actual 8→9 migration path and checks that the board table exists and the old schema objects remain.

On the product-scope question, I would like to separate PR fidelity from contract re-scoping:

• Fidelity to product(desktop): capture deferred work in a project-aware Work Board #2560: every semantic in this PR maps to the maintainer-approved Phase 0 contract from liugddx's review (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)) and the accepted revision (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)). Most of the surface you listed is load-bearing for that contract: pagination and archive/delete replaced the total-item cap the maintainer removed; revision/CAS was explicitly requested for concurrent renderer writes; provenance variants are required for side-chat capture to survive fork deletion; stable identity is the reference point Phase 3 "start as task" will need.

• RFC: Radically slim the Session Task Ledger #2290's Option 2 governs SessionTodo, not Work Board: the explicit-absent list in RFC: Radically slim the Session Task Ledger #2290 applies to the model-authored, Session-local progress snapshot. Work Board is a different owner (user-owned, cross-Session). Your own acceptance comment in RFC: Radically slim the Session Task Ledger #2290 states that product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 may proceed independently and should not become a P3 integration dependency of RFC: Radically slim the Session Task Ledger #2290 (RFC: Radically slim the Session Task Ledger #2290 (comment)).

The one item I agree has no Phase 0 consumer today is linkedSessions: the field exists in the schema, but Phase 0 has no mutation path that writes it and no UI or runtime caller reads it; Phase 3 "start as task" is the intended consumer. Rather than removing a maintainer-approved field unilaterally, I would like a decision.

@liugddx, could you please confirm:

(a) Does Phase 0 remain the approved contract after #2290 Option 2, or should it be re-scoped to capture / list / complete / delete with optional project and source context?

(b) Should linkedSessions stay in schema v1, or move to Phase 3 via a future additive migration?

(c) Is the linked-session projection formally deferred (removed from the Phase 0 deliverables), or do you want it implemented in Phase 0 against the canonical SessionContinuitySnapshot / TurnSnapshot?

I will not push further commits until these are resolved.

简体中文

感谢 review。三个实现问题我都已核验并在 476eb218b 修复：

1. Revision CAS：update / archive / unarchive / remove 现在把“读取 → revision 校验 → 写入”完整放进同一个 BEGIN IMMEDIATE 事务。进程内 write queue 保留用于单进程串行化；事务关闭跨进程竞争窗口。我已确认共享事务助手会扁平化嵌套的 #writeItem 调用，不会提前提交。

2. Linked-session projection：work-board-session-projection.ts（模块、测试、package export）已删除。它是一套平行 DTO，用 Core TurnStatus 校验，无法表达 canonical continuity 中的 waiting_for_user / cancelled。Phase 0 没有生产消费者，我同意推迟到 Phase 3，并放到真实 Runtime Host / Desktop continuity adapter 旁边实现。

3. 索引：schema v9 现在包含 (scope_kind, project_id, updated_at DESC, item_id DESC) 和 (updated_at DESC, item_id DESC)。我用真实填充数据跑了 EXPLAIN QUERY PLAN：默认 unscoped 查询、scoped 查询（project 与 inbox）以及两种 cursor 形态都使用索引，不再全表扫描或临时排序。

Migration 测试现在用发布的 v0.1.6 operational-state fixture + 精确的 v8 workflow DDL 构造真实 schema-8 库，走完整 8→9 迁移路径，并断言新表存在、旧 schema 对象保留。

关于产品范围问题，我想把“PR 是否忠实”和“契约是否要重新收缩”分开：

• 对 product(desktop): capture deferred work in a project-aware Work Board #2560 的忠实度：本 PR 的每个 semantic 都能对应 liugddx 的 maintainer review（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294753604）和已接受的修订版（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294956443）。你点名的多数复杂度都是该契约的承重结构：分页和 archive/delete 替代了 maintainer 移除的总上限；revision/CAS 是并发 renderer 写入的明确要求；provenance variants 是 side-chat 捕获在 fork 删除后仍可追溯的验收条件；stable identity 是 Phase 3 “start as task” 需要的引用点。

• RFC: Radically slim the Session Task Ledger #2290 Option 2 约束的是 SessionTodo，不是 Work Board：RFC: Radically slim the Session Task Ledger #2290 的 explicitly-absent 列表针对 model-authored、Session-local 的进度快照。Work Board 是不同的 owner（user-owned、cross-Session）。你在 RFC: Radically slim the Session Task Ledger #2290 的接受评论里也明确写了 product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 可以独立推进，不应成为 RFC: Radically slim the Session Task Ledger #2290 的 P3 集成依赖（https://github.com/maka-agent/maka-agent/issues/2290#issuecomment-5298957426）。

我唯一同意“Phase 0 没有消费者”的是 linkedSessions：字段在 schema 里，但 Phase 0 没有任何 mutation 路径写入它，也没有 UI 或 runtime 调用方读取；Phase 3 “start as task” 才是消费者。与其单方面删除 maintainer 已批准的字段，我希望得到一个明确决定。

@liugddx 能否确认：

(a) #2290 Option 2 之后，Phase 0 是否仍然以已批准契约为准，还是收缩为 capture / list / complete / delete + 可选的 project/source context？

(b) linkedSessions 留在 schema v1，还是移到 Phase 3（未来 additive migration）？

(c) linked-session projection 是否正式推迟（从 Phase 0 交付物移除），还是要求在 Phase 0 基于 canonical SessionContinuitySnapshot / TurnSnapshot 实现？

在得到答复前我不会再 push 新 commit。

[liugddx]

Thanks for addressing Astro-Han's review carefully. I rechecked the updated implementation against the approved #2560 Phase 0 contract and the later #2290 Option 2 boundary.

My maintainer decisions are:

1. Phase 0 remains an independently approved Work Board contract.#2290 Option 2 narrows the model-authored, Session-local SessionTodo; it does not re-scope the user-owned, cross-Session Work Board into the same domain. The broader Phase 0 contract therefore does not need to be reduced to a generic Todo list solely because of #2290.
2. Move linkedSessions to Phase 3. It has no Phase 0 consumer, and it is already exposed as writable input through CreateWorkBoardItemInput and persisted by the create normalizer, so it is not merely a harmless reserved field. An additive migration when “start as task” has a real caller is the smaller and safer compatibility commitment.
3. The linked-session projection is formally deferred to Phase 3. Removing the parallel DTO was correct. Implement it beside the real Runtime Host/Desktop continuity adapter against canonical SessionContinuitySnapshot / TurnSnapshot facts when the consumer exists.

The CAS fix is correct: the read, revision check, and write now share one BEGIN IMMEDIATE transaction. The schema-8 upgrade fixture is also a meaningful improvement.

One implementation issue remains before merge: the index fix removes the temporary sort but does not bound filtering work for the default query. list() adds archived = 0, while neither ordering index contains archived. With an unbounded number of archived rows and few active rows, SQLite may still walk most of the ordering index to produce one active page. EXPLAIN QUERY PLAN reporting an index scan and no temporary B-tree does not disprove that scan cost.

Please add active-row partial indexes for both unscoped and scoped query shapes (or an equivalent design), and cover the archive-heavy case. After removing linkedSessions from the Phase 0 contract/store/tests and closing this remaining query-cost hole, the PR will match the approved authority boundary and be ready for another pass.

简体中文

感谢你认真处理 Astro-Han 的评审。我重新对照了已批准的 #2560 Phase 0 契约和后续 #2290 Option 2 的权威边界。

我的 maintainer 决策如下：

1. Phase 0 继续作为独立批准的 Work Board 契约推进。#2290 Option 2 收缩的是模型写入、Session-local 的 SessionTodo，并没有把用户拥有、跨 Session 的 Work Board 收缩进同一个领域。因此，不能仅因为 #2290 就把完整 Phase 0 再缩成普通 Todo 列表。
2. linkedSessions 移到 Phase 3。 Phase 0 没有消费者，而且它已经通过 CreateWorkBoardItemInput 暴露为可写输入，并由 create normalizer 持久化，所以它并不是一个无害的预留字段。等“启动为任务”出现真实调用方时，通过增量迁移增加，是更小、更安全的兼容性承诺。
3. linked-session projection 正式推迟到 Phase 3。 删除平行 DTO 是正确的。等真实消费者出现时，再放到 Runtime Host/Desktop continuity adapter 旁，基于规范的 SessionContinuitySnapshot / TurnSnapshot 事实实现。

CAS 修复成立：读取、revision 校验和写入现在位于同一个 BEGIN IMMEDIATE 事务中。真实 schema-8 升级 fixture 也是有意义的改进。

合并前还剩一个实现问题：索引修复消除了临时排序，但没有限制默认查询的过滤工作量。list() 会添加 archived = 0，但两个排序索引都不包含 archived。当归档记录无上限、活动记录很少时，SQLite 为返回一页活动事项仍可能遍历排序索引中的大多数记录。EXPLAIN QUERY PLAN 显示使用索引且没有临时 B-tree，并不能证明扫描成本受限。

请为 scoped 和 unscoped 的活动项查询增加 partial indexes（或等价设计），并覆盖“绝大多数记录已归档”的情况。删除 Phase 0 contract/store/tests 中的 linkedSessions，并补齐这个查询成本缺口后，本 PR 就能符合已批准的权威边界，可以进入下一轮评审。

📝 Walkthrough

Summary

• Problem solved

  • Adds the Phase 0 Work Board contract and durable SQLite storage.
  • Supports validated item creation, updates, listing, archiving, restoring, and removal.
  • Adds bounded cursor pagination, provenance checks, lifecycle invariants, semantic patches, and revision-based optimistic concurrency.
  • Detects corrupt records and rejects invalid scope, project, revision, timestamp, and archive data.

• Source of truth

  • Extends the existing packages/core contract and packages/storage SQLite workflow schema.
  • Does not create a parallel linked-session path. linkedSessions and linked-session projection remain deferred to Phase 3.

• Implementation scope

  • Provides the smallest coherent Phase 0 solution.
  • BEGIN IMMEDIATE transactions and the process-local write queue are necessary for serialized mutations and revision checks.
  • Schema migration 8→9 and active, scoped, cursor, and archive indexes support compatibility and query performance.

• Simplification

  • The removed linked-session projection does not reduce Phase 0 behavior or regression coverage.
  • Task Ledger, Runtime Host, model-visible tools, recovery state, result references, and automatic completion remain outside this change.
  • No further deletion or simplification is apparent without weakening behavior or regression coverage.

• Risks and validation

  • Main risks include migration compatibility, concurrent revision conflicts, pagination correctness, SQLite constraint enforcement, timestamp ordering, cursor scope binding, and corrupt-record detection.
  • Tests cover contract behavior, storage operations, worker-thread and cross-process CAS races, pagination, query plans, corruption, constraints, migration, and backup/restore.
  • Reported validation includes passing focused tests, successful builds and typechecks for both packages, and clean Biome checks.
  • Required-check status remains unverified because no direct repository check result is available.

Review-relevant risks

• The PR changes public packages/core and packages/storage exports and adds a durable SQLite schema migration. These are public-contract and release-affecting changes. Material changes in these areas require independent human review under repository policy.
• The PR changes persisted data behavior, including archive-before-delete enforcement, scope/project constraints, migrations, and corruption handling. These changes can affect user data and operational recovery. Material changes in these areas require independent human review under repository policy.
• No security, licensing, or governance effect was identified in the current diff.
• The person performing the merge reviews the final diff. A maintainer makes the final determination.

Thanks for the maintainer decisions. I've applied them in 833481e64:

• linkedSessions is removed from the Phase 0 contract, create input, store, and tests. The Phase 0 normalizer and decoder now reject the field (fail-closed), and the contract doc records it as a Phase 3 addition.
• The linked-session projection stays deferred to Phase 3, documented in the contract and the PR description.
• Active-row partial indexes were added for both default query shapes: workflow_work_board_items_active_order and workflow_work_board_items_active_scope_order (both WHERE archived = 0). The existing full ordering indexes remain for includeArchived queries.
• Archive-heavy coverage: the new storage test creates 120 archived + 6 active items, asserts list behavior, and verifies via EXPLAIN QUERY PLAN that default unscoped and scoped queries use the partial indexes without a temporary sort. The migration test also asserts both partial indexes exist after the 8→9 upgrade.

Verification: core + storage focused tests pass (26 tests), both packages build/typecheck, Biome is clean.

The PR is now ready for review. Let me know if you'd like any further adjustments.

感谢 maintainer 的决定。我已在 833481e64 全部落地：

• linkedSessions 已从 Phase 0 契约、create input、store 和测试中移除；Phase 0 的 normalizer 和 decoder 现在会拒绝该字段（fail-closed），契约文档记录为 Phase 3 加入。
• linked-session projection 保持推迟到 Phase 3，已写入契约文档和 PR description。
• 为两种默认查询形态新增 active-row partial index：workflow_work_board_items_active_order 和 workflow_work_board_items_active_scope_order（均为 WHERE archived = 0）；原有全量排序索引保留给 includeArchived 查询。
• Archive-heavy 覆盖：新增 storage 测试构造 120 条 archived + 6 条 active，断言 list 行为，并用 EXPLAIN QUERY PLAN 验证默认 unscoped/scoped 查询使用 partial index、无临时排序；migration 测试同时断言 8→9 升级后两个 partial index 存在。

验证：core + storage focused tests 全部通过（26 个），两个包 build/typecheck 通过，Biome 干净。

A corrupt row can never be deleted.

remove calls #requireItem, which decodes the row and throws corrupt_record when record_json is unparseable or disagrees with the indexed columns. The fail-closed read is correct, but it also blocks the only removal path. A user who hits a corrupt item cannot repair the board.

Add a repair path. One option is to allow deletion when expectedRevision matches the indexed revision column, without decoding record_json.

The cursor does not bind to the query filters.

encodeCursor stores only updatedAt and itemId. A cursor returned by an inbox-scoped page decodes successfully and applies without complaint to a project-scoped query or to an includeArchived: true query. The caller then receives a page that looks coherent but silently starts from an unrelated position in a different result set.

Include a filter fingerprint in the cursor payload, and reject a cursor whose fingerprint does not match the current query.

Bind the query-plan assertions to the store's own SQL.

The test hand-writes the list SQL. The store builds its list SQL internally. The assertions therefore prove only that the indexes serve this copy of the query. If the store query later changes its filter shape, ORDER BY, or limit, this test stays green while the production path falls back to a scan or a temp sort.

Export the query text (or a small explainListPlan helper) from work-board-store.ts and assert the plan for that exact string.

packages/core/src/work-board.ts:494

• Unarchive can currently decrease updatedAt if now is earlier than the stored updatedAt (e.g. wall clock skew). Because list ordering/pagination uses updatedAt, clamp this to keep timestamps monotonic (see e.g. sqlite-long-term-memory-store.ts:953).

 item: {
...activeFields,
archived: false,
updatedAt: now,
revision: item.revision + 1,
},

packages/core/src/work-board.ts:476

• Archive timestamps should be monotonic even if the wall clock moves backwards; otherwise an archive mutation can decrease updatedAt and break ordering/pagination. Consider clamping both archivedAt and updatedAt to at least the current item.updatedAt (consistent with other storage authorities).

 ...item,
archived: true,
archivedAt: now,
updatedAt: now,
revision: item.revision + 1,

packages/core/src/work-board.ts:460

• updatedAt can move backwards if the caller clock moves backwards (or a test/consumer passes an older now). Since list pagination/orders are keyed on updatedAt, a decreasing timestamp can cause incorrect ordering and cursor paging anomalies. Other stores clamp mutation timestamps to be monotonic (e.g. packages/storage/src/sqlite-long-term-memory-store.ts:953, packages/storage/src/managed-secret-store.ts:430-432).

This issue also appears in the following locations of the same file:

Thanks for working through the earlier review rounds. I rechecked the current head, including the Core contract, SQLite lifecycle, migration, indexes, existing feedback, and focused store tests. The earlier CAS, linked-session projection, indexing, notes-patch, and migration-fixture findings are resolved.

I left three inline P2 comments covering exact-shape validation, monotonic mutation timestamps, and cursor/filter binding. None is a P0/P1, and I do not think this needs a broader redesign or PR split.

Two non-blocking test-truth follow-ups:

• The concurrent-mutation test uses one store, so it proves process-local serialization but would still pass without the cross-process BEGIN IMMEDIATE fix. I would keep it and name it accordingly; a worker/barrier test can cover cross-process CAS if that guarantee needs executable protection.
• The query-plan test is valuable, but it explains a handwritten copy of the list SQL rather than the SQL produced by list(). Sharing an internal query builder would keep the regression test tied to production without adding a public API.

I would keep the remaining contract, persistence, migration, archive, backup, and index tests; they cover distinct lifecycle seams rather than duplicating one another. Overall, the Work Board / SessionTodo authority split is sound, and the current Phase 0 scope is appropriately reduced.

中文对照

感谢持续处理前几轮 review。我重新检查了当前 head，包括 Core 契约、SQLite 生命周期、migration、索引、已有反馈和聚焦的 store 测试。之前的 CAS、linked-session projection、索引、notes patch 和 migration fixture 问题都已经解决。

我留下了三条 inline P2，分别涉及：

• 对 Work Board item 和 mutation input 进行 exact-shape 校验，避免未知字段被静默接受或在下一次写入时丢失；
• 在持久化事务中保持 mutation timestamp 单调，避免系统时钟回拨破坏 keyset pagination；
• 将 opaque cursor 与规范化后的 scope / includeArchived filters 绑定，避免跨结果集复用时静默漏项。

它们都不是 P0/P1，也不需要扩大成整体重构或拆分 PR。

另外有两项非阻塞的测试真实性建议：

• 当前并发 mutation 测试使用同一个 store，因此证明的是进程内串行化；即使没有跨进程 BEGIN IMMEDIATE 修复，它仍会通过。建议保留并让测试名称准确表达该范围；如需可执行地保护跨进程 CAS，再补 worker/barrier 测试。
• Query-plan 测试有价值，但它解释的是手写的 list SQL 副本，而不是 list() 实际生成的 SQL。共享内部 query builder 可以防止测试与生产查询逐渐漂移，同时不需要扩大公共 API。

其余 contract、persistence、migration、archive、backup 和 index 测试覆盖不同生命周期，不建议删除。总体而言，Work Board 与 SessionTodo 的权威边界正确，Phase 0 的当前范围也已经合理收缩。

AI-assisted review disclosure: Codex performed the primary lifecycle review and executable reproductions; three independent Codex reviewers covered contract scope, SQLite behavior, and test truthfulness; Claude performed a focused adversarial adjudication. The final findings were verified against the current PR head.

packages/storage/src/work-board-store.ts:358

• workBoardFilterFingerprint embeds the full projectId (max 160 chars) into filterFingerprint, but decodeCursor rejects fingerprints longer than 128 and the contract bounds cursor strings to 256 chars. For long project IDs this will produce an overlong cursor (and/or an undecodable cursor), causing pagination to fail after the first page with "cursor does not match the list filters".

• The cursor test now confirms that the second page has a different item ID.
• WorkBoardStore.list() and the query-plan test both use buildWorkBoardListStatement.
• The migration guard returns before migrateSqliteWorkflowDatabase on a current target schema. The DROP INDEX does not run on normal opens.

The remaining implementation findings are addressed. The index-rebuild finding remains withdrawn.

Learning: In `packages/storage/src/sqlite-workflow-schema.ts`, `migrateSqliteWorkflowDatabase` intentionally drops and recreates `workflow_work_board_items_scope_order`. An intermediate Phase 0 development build created the same index name with `item_id ASC` while registering schema version 9. `inspectAndMigrateOperationalState` only runs this migration when the schema registry or target schema does not match, so the drop executes only during migration. SQLite `CREATE INDEX IF NOT EXISTS` cannot replace the old same-name index definition.

• With threadId imported, prefer it over process.pid for the per-worker title suffix (worker threads share a PID).

 { title: `worker-${process.pid}` },

packages/storage/src/tests/work-board-store.test.ts:352

• This test name says “cross-process”, but it uses Worker from node:worker_threads, which is cross-thread (same process) rather than cross-process. Either rename the test to match what it actually exercises, or switch to a child-process based worker if you truly need a cross-process regression.

• If you keep using worker threads here, process.pid is the same across all workers, which makes the “winner” update harder to distinguish when debugging. Importing and using threadId gives each worker a unique identifier within the process.

Follow-up: I reviewed the current head (688051767). The requested Phase 0 scope changes, active-row partial indexes with archive-heavy coverage, and Astro-Han’s subsequent P2 findings are resolved. The remaining test-truth caveat is non-blocking. This PR is ready to merge.

[liugddx]

Approved. The current head satisfies the approved Phase 0 contract and resolves the outstanding review findings.

[Astro-Han]

Thanks for carrying the earlier review rounds through to a coherent Phase 0 boundary. I rechecked the current head after the maintainer approval, including the Core contract, SQLite lifecycle, migration/index paths, prior feedback, and focused tests.

The previous CAS transaction, linked-session deferral, active-row indexes, monotonic mutation timestamps, filter-bound cursors, and cursor-size fixes all hold. I found two remaining runtime-boundary gaps and left them inline:

• create/stored notes still accepts null even though that clear signal belongs only to update patches;
• unknown mutation-option keys can silently disable expectedRevision CAS.

Both are narrow exact-validation fixes at the existing owners. They do not call for reopening the product scope, redesigning the store, or splitting this PR.

Focused verification on 688051767:

• @maka/core build: passed
• @maka/storage build: passed
• Work Board storage test file: 17/17 passed
• visible GitHub checks: green

Once the two inline issues are addressed, this should only need a quick final pass.

感谢把前几轮 review 收敛成连贯的 Phase 0 边界。我在 maintainer Approve 之后重新检查了同一个当前 head，包括 Core 契约、SQLite 生命周期、migration/index、已有反馈和聚焦测试。

此前的 CAS 事务、linked-session 推迟、active partial indexes、mutation 时间戳单调性、游标与过滤条件绑定，以及游标长度问题都已经正确解决。

目前还剩两个运行时边界缺口，已分别留下 inline comment：create/持久化记录仍会接受 notes: null；mutation options 的未知字段可能静默关闭 expectedRevision CAS。两者都只需要在现有 owner 上补齐精确校验，不需要重新讨论产品范围、重构 store 或拆分 PR。

Astro-Han — both P2 inline comments are fixed in cbf2dc64a (details in the threads):

• notes: null is now rejected in create input and stored records; null remains the explicit clear signal only in update patches.
• Mutation options are validated as an exact-shape object, so unknown keys like expectedRevison or extra fields throw invalid_input instead of silently disabling expectedRevision CAS.

Verification: core + storage focused tests pass (33 tests), both packages build/typecheck, Biome clean. liugddx already approved the prior head; the new commit only contains these two narrow validation fixes.

Could you take the quick final pass? If everything looks good, this PR is ready to merge. @liugddx — happy to merge once Astro-Han confirms.

简体中文

Astro-Han —— 两条 P2 代码评论已在 cbf2dc64a 修复（详见对应线程）：

• create input 和已存记录现在拒绝 notes: null；null 只保留为 update patch 的显式清除信号。
• mutation options 改为精确形状校验，expectedRevison 这类拼写错误或多余字段会直接 invalid_input，不会再静默关闭 expectedRevision CAS。

验证：core + storage focused tests 全部通过（33 个），两个包 build/typecheck 通过，Biome 干净。liugddx 已对前一版 head 表示 approve；本次新 commit 只包含这两处窄校验修复。

能否做最后一次快速复核？如果没问题，这个 PR 就可以合并了。@liugddx —— Astro-Han 确认后就可以 merge。

[Astro-Han]

Thanks for the quick follow-up. I rechecked the current head (cbf2dc64a) and both remaining P2 findings are resolved:

• create input and durable records now reject notes: null, while update patches retain null as the explicit clear signal;
• mutation options now fail closed on unknown keys, so a misspelled or extra field cannot silently disable expectedRevision CAS.

The regression tests exercise the real contract/store boundaries and verify that rejected mutation options leave the stored revision and state unchanged. I found no remaining P0–P3 issues.

The Phase 0 authority boundary remains intact: Core owns the item contract, Storage owns durable mutation and CAS, and no Runtime execution state or parallel authority has been introduced. The current solution is the smallest complete implementation of the approved scope; it does not need further restructuring or a PR split.

Verification on cbf2dc64a:

• @maka/core build and focused Work Board tests: 15/15 passed
• @maka/storage build and focused Work Board tests: 18/18 passed
• Biome formatting check on the four changed files: passed
• git diff --check: passed
• visible GitHub checks: green

感谢快速处理。我重新检查了当前 head（cbf2dc64a），最后两条 P2 都已解决：

• create input 和持久化记录现在拒绝 notes: null，同时 update patch 仍保留 null 作为显式清除信号；
• mutation options 现在会拒绝未知字段，因此拼错或多余字段不会再静默关闭 expectedRevision CAS。

回归测试覆盖了真实的契约和 store 边界，并验证 mutation options 被拒绝后，持久化 revision 和 state 都不会变化。目前没有剩余 P0–P3。

Phase 0 的权威边界保持清晰：Core 负责 item contract，Storage 负责持久化 mutation 与 CAS，没有引入 Runtime 执行状态副本或平行 authority。当前方案已经是已批准范围内的最小完整实现，不需要继续重构或拆分 PR。

当前 head 的 Core/Storage build 通过，聚焦测试分别为 15/15 与 18/18，Biome、git diff --check 和 GitHub checks 均通过，merge state 为 clean。

我这边 approve。

Work Board Phase 0

This PR implements the maintainer-approved Phase 0 Work Board contract (see the 7-point review and accepted revision in #2560).

Key points:

• durable Work Board items with no total item cap
• bounded pagination (default 50, max 100)
• explicit todo/in_progress/done lifecycle
• strict provenance union (manual / main_conversation / side_conversation)
• SQLite scope/project invariant
• semantic patch mutation semantics
• monotonic revision + optional expectedRevision CAS
• serialized transactional writes (BEGIN IMMEDIATE)
• archive-before-delete semantics
• active-row partial indexes so default list queries stay bounded under archive-heavy data
• schema 8 -> 9 additive migration
• fail-closed corruption detection

Maintainer-confirmed deferrals (liugddx, #2560):

• linkedSessions moves to Phase 3; Phase 0 rejects the field in create input and stored records
• linked-session projection is deferred to Phase 3; it will be implemented beside the canonical Runtime Host / Desktop continuity adapter against SessionContinuitySnapshot / TurnSnapshot

Intentionally deferred:

• Task Ledger integration
• Runtime Host integration
• model-visible Work Board tools
• recovery/graph state
• resultRefs
• automatic completion

Verification

• core + storage focused tests pass (30 tests)
• @maka/core and @maka/storage build/typecheck
• Biome clean
• migration: v0.1.6 fixture + exact v8 DDL -> real 8->9 path; old schema objects retained; partial indexes present
• archive-heavy list queries covered by EXPLAIN QUERY PLAN regression test against the production query builder
• cross-process CAS covered by a worker-thread test (one winner, one operation_conflict)

Checklist

• Phase 0 contract matches the maintainer-approved scope and deferrals
• Migration is additive (8 -> 9) with no user-data DROP
• Tests updated and passing
• Docs and PR description current

Refs #2560

[Astro-Han]

Thanks for defining the Work Board authority boundary before adding UI or Runtime integration.

Before getting into the implementation details, I think the product scope should be reconciled with the more recent decision in #2290. That discussion deliberately reduced the Session Task Ledger to a narrow Session-local Todo snapshot: no stable item identity, per-item CRUD, hierarchy, evidence, pagination, or workflow UI.

I understand that #2560 describes a different owner: Work Board items are user-owned, cross-Session deferred intentions, while SessionTodo is a model-authored progress snapshot. I am not suggesting that Work Board should reuse SessionTodo or the Task Ledger.

The remaining question is whether this distinct product surface needs a full Work Board domain yet. This PR introduces another durable task-like entity with stable IDs, per-item mutations, scopes, provenance variants, a state machine, archive/delete behavior, pagination, revisions, and future Session links—before there is a UI or production caller. That appears to reintroduce much of the product and maintenance complexity that #2290 has just removed from the existing task system.

Could we first establish why a minimal user-owned Todo list is insufficient for the actual problem of “remember this for later without interrupting the current Session”? A small vertical slice—capture, list, complete, and delete, with optional project/source context—would validate the user need without fixing the larger Board contract in schema v1. Session linking and execution projection could then be added when “start as task” has a real consumer.

If the broader Work Board scope remains intentional after that reconciliation, I found three implementation issues that seem worth resolving before the Phase 0 schema is published:

1. The revision check is outside the SQLite write transaction. Two processes can both read revision 1, both pass expectedRevision: 1, both write revision 2, and the later write silently overwrites the earlier semantic patch. Please make the read/check/write sequence one BEGIN IMMEDIATE transaction, or use conditional UPDATE/DELETE ... WHERE revision = ? statements and treat zero affected rows as a conflict.

2. The linked-session projector validates a new DTO rather than the canonical SessionContinuitySnapshot. It also uses Core TurnStatus, which rejects valid continuity states such as waiting_for_user and cancelled. Since there is no production consumer yet, the simplest option may be to defer this projector until it can live beside the real Runtime Host/Desktop continuity adapter instead of introducing a parallel contract now.

3. The new index does not satisfy the list ordering. The default unscoped query performs a full-table scan and temporary sort, while scoped queries still require a temporary sort for the final key because item_id has the opposite direction. Since the contract intentionally has no total item cap, pagination currently bounds returned rows but not query work. Please align the indexes with the actual scoped/unscoped query shapes before schema v9 is released.

The focused tests and current CI are green. I would also replace the fresh-database “migration” test with a real schema-8 upgrade fixture, but I see that as a verification improvement rather than a separate production finding.

简体中文

感谢你在增加 UI 或 Runtime 集成前，先明确 Work Board 的权威边界。

在讨论具体实现前，我认为这里的产品范围需要先与 #2290 中较新的决定重新对齐。该讨论刚刚把 Session Task Ledger 明确收缩为一个很窄的 Session-local Todo 快照：没有稳定的事项身份、逐项 CRUD、层级、证据、分页或 workflow UI。

我理解 #2560 定义的是另一个 owner：Work Board 是用户拥有的、跨 Session 的暂缓事项；SessionTodo 则是模型写入的进度快照。我并不是建议 Work Board 复用 SessionTodo 或 Task Ledger。

真正需要确认的是：这个独立的产品界面现在是否已经需要一套完整的 Work Board 领域模型。本 PR 在还没有 UI 和生产调用方时，就引入了另一个持久化的 task-like 实体，包括稳定 ID、逐项 mutation、scope、多种 provenance、状态机、归档/删除、分页、revision，以及未来的 Session 关联。这似乎重新引入了 #2290 刚从现有任务系统中删除的大量产品与维护复杂度。

我们是否应该先说明：对于“记住这个后续事项，但不要打断当前 Session”这一真实问题，为什么一个最小的、用户拥有的 Todo 列表还不够？先交付一条较小的纵向链路——保存、列出、完成和删除，并按需携带项目或来源上下文——就可以验证用户需求，而不必现在把更大的 Board contract 固化进 schema v1。等“启动为任务”出现真实消费者时，再增加 Session 关联和执行状态投影也不迟。

如果重新对齐后，完整的 Work Board 范围仍然是有意保留的，我还发现三个建议在发布 Phase 0 schema 前解决的实现问题：

1. revision 检查发生在 SQLite 写事务之外。两个进程可以同时读到 revision 1，都通过 expectedRevision: 1，然后分别写入 revision 2；后写入的 semantic patch 会静默覆盖前一次修改。建议把读取、检查和写入放进同一个 BEGIN IMMEDIATE 事务，或者使用带 WHERE revision = ? 条件的 UPDATE/DELETE，并将影响行数为零视为冲突。

2. linked-session projector 校验的是一套新定义的 DTO，而不是权威的 SessionContinuitySnapshot。它还使用了 Core TurnStatus，因此会拒绝 waiting_for_user、cancelled 等合法的 continuity 状态。当前还没有生产调用方，最简单的方案可能是先推迟这个 projector，等真实的 Runtime Host/Desktop continuity adapter 出现时再贴近实际 owner 实现，避免现在引入一份平行契约。

3. 新增索引不能满足 list 的实际排序。默认的无 scope 查询会全表扫描并临时排序；scoped 查询也会因为 item_id 的索引方向与查询相反，对最后一个排序键进行临时排序。由于契约明确不设置事项总量上限，目前分页只限制了返回行数，并没有限制每页查询的工作量。建议在 schema v9 发布前，让索引与 scoped/unscoped 查询的真实形态一致。

Focused tests 和当前 CI 均已通过。我还建议把“从空数据库创建 v9”的 migration 测试替换成真实的 schema 8 升级 fixture，不过这属于验证改进，不是独立的生产 finding。

[somewan820]

Thanks for the review. I have verified all three implementation findings and fixed them in 476eb218b:

1. Revision CAS — update / archive / unarchive / remove now run the full read → revision check → write sequence inside one BEGIN IMMEDIATE transaction. The in-process write queue is retained for process-local serialization; the transaction closes the cross-process race. I confirmed the shared transaction helper flattens the nested #writeItem call, so there is no premature commit.

2. Linked-session projection — work-board-session-projection.ts (module, test, and package export) is removed. It was a parallel DTO validated with Core TurnStatus, which cannot represent waiting_for_user / cancelled from the canonical continuity contract. With no production consumer in Phase 0, I agree the projector should wait until Phase 3 and live beside the real Runtime Host / Desktop continuity adapter.

3. Indexes — schema v9 now ships (scope_kind, project_id, updated_at DESC, item_id DESC) and (updated_at DESC, item_id DESC). I verified against populated data with EXPLAIN QUERY PLAN: the default unscoped query, scoped queries (project and inbox), and both cursor forms use the indexes and no longer perform a full-table scan or temporary sort.

The migration test now builds a real schema-8 database from the released v0.1.6 operational-state fixture plus the exact v8 workflow DDL, then runs the actual 8→9 migration path and checks that the board table exists and the old schema objects remain.

On the product-scope question, I would like to separate PR fidelity from contract re-scoping:

• Fidelity to product(desktop): capture deferred work in a project-aware Work Board #2560: every semantic in this PR maps to the maintainer-approved Phase 0 contract from liugddx's review (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)) and the accepted revision (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)). Most of the surface you listed is load-bearing for that contract: pagination and archive/delete replaced the total-item cap the maintainer removed; revision/CAS was explicitly requested for concurrent renderer writes; provenance variants are required for side-chat capture to survive fork deletion; stable identity is the reference point Phase 3 "start as task" will need.

• RFC: Radically slim the Session Task Ledger #2290's Option 2 governs SessionTodo, not Work Board: the explicit-absent list in RFC: Radically slim the Session Task Ledger #2290 applies to the model-authored, Session-local progress snapshot. Work Board is a different owner (user-owned, cross-Session). Your own acceptance comment in RFC: Radically slim the Session Task Ledger #2290 states that product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 may proceed independently and should not become a P3 integration dependency of RFC: Radically slim the Session Task Ledger #2290 (RFC: Radically slim the Session Task Ledger #2290 (comment)).

The one item I agree has no Phase 0 consumer today is linkedSessions: the field exists in the schema, but Phase 0 has no mutation path that writes it and no UI or runtime caller reads it; Phase 3 "start as task" is the intended consumer. Rather than removing a maintainer-approved field unilaterally, I would like a decision.

@liugddx, could you please confirm:

(a) Does Phase 0 remain the approved contract after #2290 Option 2, or should it be re-scoped to capture / list / complete / delete with optional project and source context?

(b) Should linkedSessions stay in schema v1, or move to Phase 3 via a future additive migration?

(c) Is the linked-session projection formally deferred (removed from the Phase 0 deliverables), or do you want it implemented in Phase 0 against the canonical SessionContinuitySnapshot / TurnSnapshot?

I will not push further commits until these are resolved.

简体中文

感谢 review。三个实现问题我都已核验并在 476eb218b 修复：

1. Revision CAS：update / archive / unarchive / remove 现在把“读取 → revision 校验 → 写入”完整放进同一个 BEGIN IMMEDIATE 事务。进程内 write queue 保留用于单进程串行化；事务关闭跨进程竞争窗口。我已确认共享事务助手会扁平化嵌套的 #writeItem 调用，不会提前提交。

2. Linked-session projection：work-board-session-projection.ts（模块、测试、package export）已删除。它是一套平行 DTO，用 Core TurnStatus 校验，无法表达 canonical continuity 中的 waiting_for_user / cancelled。Phase 0 没有生产消费者，我同意推迟到 Phase 3，并放到真实 Runtime Host / Desktop continuity adapter 旁边实现。

3. 索引：schema v9 现在包含 (scope_kind, project_id, updated_at DESC, item_id DESC) 和 (updated_at DESC, item_id DESC)。我用真实填充数据跑了 EXPLAIN QUERY PLAN：默认 unscoped 查询、scoped 查询（project 与 inbox）以及两种 cursor 形态都使用索引，不再全表扫描或临时排序。

Migration 测试现在用发布的 v0.1.6 operational-state fixture + 精确的 v8 workflow DDL 构造真实 schema-8 库，走完整 8→9 迁移路径，并断言新表存在、旧 schema 对象保留。

关于产品范围问题，我想把“PR 是否忠实”和“契约是否要重新收缩”分开：

• 对 product(desktop): capture deferred work in a project-aware Work Board #2560 的忠实度：本 PR 的每个 semantic 都能对应 liugddx 的 maintainer review（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294753604）和已接受的修订版（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294956443）。你点名的多数复杂度都是该契约的承重结构：分页和 archive/delete 替代了 maintainer 移除的总上限；revision/CAS 是并发 renderer 写入的明确要求；provenance variants 是 side-chat 捕获在 fork 删除后仍可追溯的验收条件；stable identity 是 Phase 3 “start as task” 需要的引用点。

• RFC: Radically slim the Session Task Ledger #2290 Option 2 约束的是 SessionTodo，不是 Work Board：RFC: Radically slim the Session Task Ledger #2290 的 explicitly-absent 列表针对 model-authored、Session-local 的进度快照。Work Board 是不同的 owner（user-owned、cross-Session）。你在 RFC: Radically slim the Session Task Ledger #2290 的接受评论里也明确写了 product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 可以独立推进，不应成为 RFC: Radically slim the Session Task Ledger #2290 的 P3 集成依赖（https://github.com/maka-agent/maka-agent/issues/2290#issuecomment-5298957426）。

我唯一同意“Phase 0 没有消费者”的是 linkedSessions：字段在 schema 里，但 Phase 0 没有任何 mutation 路径写入它，也没有 UI 或 runtime 调用方读取；Phase 3 “start as task” 才是消费者。与其单方面删除 maintainer 已批准的字段，我希望得到一个明确决定。

@liugddx 能否确认：

(a) #2290 Option 2 之后，Phase 0 是否仍然以已批准契约为准，还是收缩为 capture / list / complete / delete + 可选的 project/source context？

(b) linkedSessions 留在 schema v1，还是移到 Phase 3（未来 additive migration）？

(c) linked-session projection 是否正式推迟（从 Phase 0 交付物移除），还是要求在 Phase 0 基于 canonical SessionContinuitySnapshot / TurnSnapshot 实现？

在得到答复前我不会再 push 新 commit。

[liugddx]

Thanks for addressing Astro-Han's review carefully. I rechecked the updated implementation against the approved #2560 Phase 0 contract and the later #2290 Option 2 boundary.

My maintainer decisions are:

1. Phase 0 remains an independently approved Work Board contract.#2290 Option 2 narrows the model-authored, Session-local SessionTodo; it does not re-scope the user-owned, cross-Session Work Board into the same domain. The broader Phase 0 contract therefore does not need to be reduced to a generic Todo list solely because of #2290.
2. Move linkedSessions to Phase 3. It has no Phase 0 consumer, and it is already exposed as writable input through CreateWorkBoardItemInput and persisted by the create normalizer, so it is not merely a harmless reserved field. An additive migration when “start as task” has a real caller is the smaller and safer compatibility commitment.
3. The linked-session projection is formally deferred to Phase 3. Removing the parallel DTO was correct. Implement it beside the real Runtime Host/Desktop continuity adapter against canonical SessionContinuitySnapshot / TurnSnapshot facts when the consumer exists.

The CAS fix is correct: the read, revision check, and write now share one BEGIN IMMEDIATE transaction. The schema-8 upgrade fixture is also a meaningful improvement.

One implementation issue remains before merge: the index fix removes the temporary sort but does not bound filtering work for the default query. list() adds archived = 0, while neither ordering index contains archived. With an unbounded number of archived rows and few active rows, SQLite may still walk most of the ordering index to produce one active page. EXPLAIN QUERY PLAN reporting an index scan and no temporary B-tree does not disprove that scan cost.

Please add active-row partial indexes for both unscoped and scoped query shapes (or an equivalent design), and cover the archive-heavy case. After removing linkedSessions from the Phase 0 contract/store/tests and closing this remaining query-cost hole, the PR will match the approved authority boundary and be ready for another pass.

简体中文

感谢你认真处理 Astro-Han 的评审。我重新对照了已批准的 #2560 Phase 0 契约和后续 #2290 Option 2 的权威边界。

我的 maintainer 决策如下：

1. Phase 0 继续作为独立批准的 Work Board 契约推进。#2290 Option 2 收缩的是模型写入、Session-local 的 SessionTodo，并没有把用户拥有、跨 Session 的 Work Board 收缩进同一个领域。因此，不能仅因为 #2290 就把完整 Phase 0 再缩成普通 Todo 列表。
2. linkedSessions 移到 Phase 3。 Phase 0 没有消费者，而且它已经通过 CreateWorkBoardItemInput 暴露为可写输入，并由 create normalizer 持久化，所以它并不是一个无害的预留字段。等“启动为任务”出现真实调用方时，通过增量迁移增加，是更小、更安全的兼容性承诺。
3. linked-session projection 正式推迟到 Phase 3。 删除平行 DTO 是正确的。等真实消费者出现时，再放到 Runtime Host/Desktop continuity adapter 旁，基于规范的 SessionContinuitySnapshot / TurnSnapshot 事实实现。

CAS 修复成立：读取、revision 校验和写入现在位于同一个 BEGIN IMMEDIATE 事务中。真实 schema-8 升级 fixture 也是有意义的改进。

合并前还剩一个实现问题：索引修复消除了临时排序，但没有限制默认查询的过滤工作量。list() 会添加 archived = 0，但两个排序索引都不包含 archived。当归档记录无上限、活动记录很少时，SQLite 为返回一页活动事项仍可能遍历排序索引中的大多数记录。EXPLAIN QUERY PLAN 显示使用索引且没有临时 B-tree，并不能证明扫描成本受限。

请为 scoped 和 unscoped 的活动项查询增加 partial indexes（或等价设计），并覆盖“绝大多数记录已归档”的情况。删除 Phase 0 contract/store/tests 中的 linkedSessions，并补齐这个查询成本缺口后，本 PR 就能符合已批准的权威边界，可以进入下一轮评审。

📝 Walkthrough

Summary

• Problem solved

  • Adds the Phase 0 Work Board contract and durable SQLite storage.
  • Supports validated item creation, updates, listing, archiving, restoring, and removal.
  • Adds bounded cursor pagination, provenance checks, lifecycle invariants, semantic patches, and revision-based optimistic concurrency.
  • Detects corrupt records and rejects invalid scope, project, revision, timestamp, and archive data.

• Source of truth

  • Extends the existing packages/core contract and packages/storage SQLite workflow schema.
  • Does not create a parallel linked-session path. linkedSessions and linked-session projection remain deferred to Phase 3.

• Implementation scope

  • Provides the smallest coherent Phase 0 solution.
  • BEGIN IMMEDIATE transactions and the process-local write queue are necessary for serialized mutations and revision checks.
  • Schema migration 8→9 and active, scoped, cursor, and archive indexes support compatibility and query performance.

• Simplification

  • The removed linked-session projection does not reduce Phase 0 behavior or regression coverage.
  • Task Ledger, Runtime Host, model-visible tools, recovery state, result references, and automatic completion remain outside this change.
  • No further deletion or simplification is apparent without weakening behavior or regression coverage.

• Risks and validation

  • Main risks include migration compatibility, concurrent revision conflicts, pagination correctness, SQLite constraint enforcement, timestamp ordering, cursor scope binding, and corrupt-record detection.
  • Tests cover contract behavior, storage operations, worker-thread and cross-process CAS races, pagination, query plans, corruption, constraints, migration, and backup/restore.
  • Reported validation includes passing focused tests, successful builds and typechecks for both packages, and clean Biome checks.
  • Required-check status remains unverified because no direct repository check result is available.

Review-relevant risks

• The PR changes public packages/core and packages/storage exports and adds a durable SQLite schema migration. These are public-contract and release-affecting changes. Material changes in these areas require independent human review under repository policy.
• The PR changes persisted data behavior, including archive-before-delete enforcement, scope/project constraints, migrations, and corruption handling. These changes can affect user data and operational recovery. Material changes in these areas require independent human review under repository policy.
• No security, licensing, or governance effect was identified in the current diff.
• The person performing the merge reviews the final diff. A maintainer makes the final determination.

Thanks for the maintainer decisions. I've applied them in 833481e64:

• linkedSessions is removed from the Phase 0 contract, create input, store, and tests. The Phase 0 normalizer and decoder now reject the field (fail-closed), and the contract doc records it as a Phase 3 addition.
• The linked-session projection stays deferred to Phase 3, documented in the contract and the PR description.
• Active-row partial indexes were added for both default query shapes: workflow_work_board_items_active_order and workflow_work_board_items_active_scope_order (both WHERE archived = 0). The existing full ordering indexes remain for includeArchived queries.
• Archive-heavy coverage: the new storage test creates 120 archived + 6 active items, asserts list behavior, and verifies via EXPLAIN QUERY PLAN that default unscoped and scoped queries use the partial indexes without a temporary sort. The migration test also asserts both partial indexes exist after the 8→9 upgrade.

Verification: core + storage focused tests pass (26 tests), both packages build/typecheck, Biome is clean.

The PR is now ready for review. Let me know if you'd like any further adjustments.

感谢 maintainer 的决定。我已在 833481e64 全部落地：

• linkedSessions 已从 Phase 0 契约、create input、store 和测试中移除；Phase 0 的 normalizer 和 decoder 现在会拒绝该字段（fail-closed），契约文档记录为 Phase 3 加入。
• linked-session projection 保持推迟到 Phase 3，已写入契约文档和 PR description。
• 为两种默认查询形态新增 active-row partial index：workflow_work_board_items_active_order 和 workflow_work_board_items_active_scope_order（均为 WHERE archived = 0）；原有全量排序索引保留给 includeArchived 查询。
• Archive-heavy 覆盖：新增 storage 测试构造 120 条 archived + 6 条 active，断言 list 行为，并用 EXPLAIN QUERY PLAN 验证默认 unscoped/scoped 查询使用 partial index、无临时排序；migration 测试同时断言 8→9 升级后两个 partial index 存在。

验证：core + storage focused tests 全部通过（26 个），两个包 build/typecheck 通过，Biome 干净。

A corrupt row can never be deleted.

remove calls #requireItem, which decodes the row and throws corrupt_record when record_json is unparseable or disagrees with the indexed columns. The fail-closed read is correct, but it also blocks the only removal path. A user who hits a corrupt item cannot repair the board.

Add a repair path. One option is to allow deletion when expectedRevision matches the indexed revision column, without decoding record_json.

The cursor does not bind to the query filters.

encodeCursor stores only updatedAt and itemId. A cursor returned by an inbox-scoped page decodes successfully and applies without complaint to a project-scoped query or to an includeArchived: true query. The caller then receives a page that looks coherent but silently starts from an unrelated position in a different result set.

Include a filter fingerprint in the cursor payload, and reject a cursor whose fingerprint does not match the current query.

Bind the query-plan assertions to the store's own SQL.

The test hand-writes the list SQL. The store builds its list SQL internally. The assertions therefore prove only that the indexes serve this copy of the query. If the store query later changes its filter shape, ORDER BY, or limit, this test stays green while the production path falls back to a scan or a temp sort.

Export the query text (or a small explainListPlan helper) from work-board-store.ts and assert the plan for that exact string.

packages/core/src/work-board.ts:494

• Unarchive can currently decrease updatedAt if now is earlier than the stored updatedAt (e.g. wall clock skew). Because list ordering/pagination uses updatedAt, clamp this to keep timestamps monotonic (see e.g. sqlite-long-term-memory-store.ts:953).

 item: {
...activeFields,
archived: false,
updatedAt: now,
revision: item.revision + 1,
},

packages/core/src/work-board.ts:476

• Archive timestamps should be monotonic even if the wall clock moves backwards; otherwise an archive mutation can decrease updatedAt and break ordering/pagination. Consider clamping both archivedAt and updatedAt to at least the current item.updatedAt (consistent with other storage authorities).

 ...item,
archived: true,
archivedAt: now,
updatedAt: now,
revision: item.revision + 1,

packages/core/src/work-board.ts:460

• updatedAt can move backwards if the caller clock moves backwards (or a test/consumer passes an older now). Since list pagination/orders are keyed on updatedAt, a decreasing timestamp can cause incorrect ordering and cursor paging anomalies. Other stores clamp mutation timestamps to be monotonic (e.g. packages/storage/src/sqlite-long-term-memory-store.ts:953, packages/storage/src/managed-secret-store.ts:430-432).

This issue also appears in the following locations of the same file:

Thanks for working through the earlier review rounds. I rechecked the current head, including the Core contract, SQLite lifecycle, migration, indexes, existing feedback, and focused store tests. The earlier CAS, linked-session projection, indexing, notes-patch, and migration-fixture findings are resolved.

I left three inline P2 comments covering exact-shape validation, monotonic mutation timestamps, and cursor/filter binding. None is a P0/P1, and I do not think this needs a broader redesign or PR split.

Two non-blocking test-truth follow-ups:

• The concurrent-mutation test uses one store, so it proves process-local serialization but would still pass without the cross-process BEGIN IMMEDIATE fix. I would keep it and name it accordingly; a worker/barrier test can cover cross-process CAS if that guarantee needs executable protection.
• The query-plan test is valuable, but it explains a handwritten copy of the list SQL rather than the SQL produced by list(). Sharing an internal query builder would keep the regression test tied to production without adding a public API.

I would keep the remaining contract, persistence, migration, archive, backup, and index tests; they cover distinct lifecycle seams rather than duplicating one another. Overall, the Work Board / SessionTodo authority split is sound, and the current Phase 0 scope is appropriately reduced.

中文对照

感谢持续处理前几轮 review。我重新检查了当前 head，包括 Core 契约、SQLite 生命周期、migration、索引、已有反馈和聚焦的 store 测试。之前的 CAS、linked-session projection、索引、notes patch 和 migration fixture 问题都已经解决。

我留下了三条 inline P2，分别涉及：

• 对 Work Board item 和 mutation input 进行 exact-shape 校验，避免未知字段被静默接受或在下一次写入时丢失；
• 在持久化事务中保持 mutation timestamp 单调，避免系统时钟回拨破坏 keyset pagination；
• 将 opaque cursor 与规范化后的 scope / includeArchived filters 绑定，避免跨结果集复用时静默漏项。

它们都不是 P0/P1，也不需要扩大成整体重构或拆分 PR。

另外有两项非阻塞的测试真实性建议：

• 当前并发 mutation 测试使用同一个 store，因此证明的是进程内串行化；即使没有跨进程 BEGIN IMMEDIATE 修复，它仍会通过。建议保留并让测试名称准确表达该范围；如需可执行地保护跨进程 CAS，再补 worker/barrier 测试。
• Query-plan 测试有价值，但它解释的是手写的 list SQL 副本，而不是 list() 实际生成的 SQL。共享内部 query builder 可以防止测试与生产查询逐渐漂移，同时不需要扩大公共 API。

其余 contract、persistence、migration、archive、backup 和 index 测试覆盖不同生命周期，不建议删除。总体而言，Work Board 与 SessionTodo 的权威边界正确，Phase 0 的当前范围也已经合理收缩。

AI-assisted review disclosure: Codex performed the primary lifecycle review and executable reproductions; three independent Codex reviewers covered contract scope, SQLite behavior, and test truthfulness; Claude performed a focused adversarial adjudication. The final findings were verified against the current PR head.

packages/storage/src/work-board-store.ts:358

• workBoardFilterFingerprint embeds the full projectId (max 160 chars) into filterFingerprint, but decodeCursor rejects fingerprints longer than 128 and the contract bounds cursor strings to 256 chars. For long project IDs this will produce an overlong cursor (and/or an undecodable cursor), causing pagination to fail after the first page with "cursor does not match the list filters".

• The cursor test now confirms that the second page has a different item ID.
• WorkBoardStore.list() and the query-plan test both use buildWorkBoardListStatement.
• The migration guard returns before migrateSqliteWorkflowDatabase on a current target schema. The DROP INDEX does not run on normal opens.

The remaining implementation findings are addressed. The index-rebuild finding remains withdrawn.

Learning: In `packages/storage/src/sqlite-workflow-schema.ts`, `migrateSqliteWorkflowDatabase` intentionally drops and recreates `workflow_work_board_items_scope_order`. An intermediate Phase 0 development build created the same index name with `item_id ASC` while registering schema version 9. `inspectAndMigrateOperationalState` only runs this migration when the schema registry or target schema does not match, so the drop executes only during migration. SQLite `CREATE INDEX IF NOT EXISTS` cannot replace the old same-name index definition.

• With threadId imported, prefer it over process.pid for the per-worker title suffix (worker threads share a PID).

 { title: `worker-${process.pid}` },

packages/storage/src/tests/work-board-store.test.ts:352

• This test name says “cross-process”, but it uses Worker from node:worker_threads, which is cross-thread (same process) rather than cross-process. Either rename the test to match what it actually exercises, or switch to a child-process based worker if you truly need a cross-process regression.

• If you keep using worker threads here, process.pid is the same across all workers, which makes the “winner” update harder to distinguish when debugging. Importing and using threadId gives each worker a unique identifier within the process.

Follow-up: I reviewed the current head (688051767). The requested Phase 0 scope changes, active-row partial indexes with archive-heavy coverage, and Astro-Han’s subsequent P2 findings are resolved. The remaining test-truth caveat is non-blocking. This PR is ready to merge.

[liugddx]

Approved. The current head satisfies the approved Phase 0 contract and resolves the outstanding review findings.

[Astro-Han]

Thanks for carrying the earlier review rounds through to a coherent Phase 0 boundary. I rechecked the current head after the maintainer approval, including the Core contract, SQLite lifecycle, migration/index paths, prior feedback, and focused tests.

The previous CAS transaction, linked-session deferral, active-row indexes, monotonic mutation timestamps, filter-bound cursors, and cursor-size fixes all hold. I found two remaining runtime-boundary gaps and left them inline:

• create/stored notes still accepts null even though that clear signal belongs only to update patches;
• unknown mutation-option keys can silently disable expectedRevision CAS.

Both are narrow exact-validation fixes at the existing owners. They do not call for reopening the product scope, redesigning the store, or splitting this PR.

Focused verification on 688051767:

• @maka/core build: passed
• @maka/storage build: passed
• Work Board storage test file: 17/17 passed
• visible GitHub checks: green

Once the two inline issues are addressed, this should only need a quick final pass.

感谢把前几轮 review 收敛成连贯的 Phase 0 边界。我在 maintainer Approve 之后重新检查了同一个当前 head，包括 Core 契约、SQLite 生命周期、migration/index、已有反馈和聚焦测试。

此前的 CAS 事务、linked-session 推迟、active partial indexes、mutation 时间戳单调性、游标与过滤条件绑定，以及游标长度问题都已经正确解决。

目前还剩两个运行时边界缺口，已分别留下 inline comment：create/持久化记录仍会接受 notes: null；mutation options 的未知字段可能静默关闭 expectedRevision CAS。两者都只需要在现有 owner 上补齐精确校验，不需要重新讨论产品范围、重构 store 或拆分 PR。

当前 head 的 Core/Storage 构建通过，Work Board storage 聚焦测试 17/17 通过，GitHub 可见检查全绿。处理完两条 inline 后，快速复核即可。

Astro-Han — both P2 inline comments are fixed in cbf2dc64a (details in the threads):

• notes: null is now rejected in create input and stored records; null remains the explicit clear signal only in update patches.
• Mutation options are validated as an exact-shape object, so unknown keys like expectedRevison or extra fields throw invalid_input instead of silently disabling expectedRevision CAS.

Verification: core + storage focused tests pass (33 tests), both packages build/typecheck, Biome clean. liugddx already approved the prior head; the new commit only contains these two narrow validation fixes.

Could you take the quick final pass? If everything looks good, this PR is ready to merge. @liugddx — happy to merge once Astro-Han confirms.

简体中文

Astro-Han —— 两条 P2 代码评论已在 cbf2dc64a 修复（详见对应线程）：

• create input 和已存记录现在拒绝 notes: null；null 只保留为 update patch 的显式清除信号。
• mutation options 改为精确形状校验，expectedRevison 这类拼写错误或多余字段会直接 invalid_input，不会再静默关闭 expectedRevision CAS。

验证：core + storage focused tests 全部通过（33 个），两个包 build/typecheck 通过，Biome 干净。liugddx 已对前一版 head 表示 approve；本次新 commit 只包含这两处窄校验修复。

能否做最后一次快速复核？如果没问题，这个 PR 就可以合并了。@liugddx —— Astro-Han 确认后就可以 merge。

[Astro-Han]

Thanks for the quick follow-up. I rechecked the current head (cbf2dc64a) and both remaining P2 findings are resolved:

• create input and durable records now reject notes: null, while update patches retain null as the explicit clear signal;
• mutation options now fail closed on unknown keys, so a misspelled or extra field cannot silently disable expectedRevision CAS.

The regression tests exercise the real contract/store boundaries and verify that rejected mutation options leave the stored revision and state unchanged. I found no remaining P0–P3 issues.

The Phase 0 authority boundary remains intact: Core owns the item contract, Storage owns durable mutation and CAS, and no Runtime execution state or parallel authority has been introduced. The current solution is the smallest complete implementation of the approved scope; it does not need further restructuring or a PR split.

Verification on cbf2dc64a:

• @maka/core build and focused Work Board tests: 15/15 passed
• @maka/storage build and focused Work Board tests: 18/18 passed
• Biome formatting check on the four changed files: passed
• git diff --check: passed
• visible GitHub checks: green
• merge state: clean

Approved from my side.

感谢快速处理。我重新检查了当前 head（cbf2dc64a），最后两条 P2 都已解决：

• create input 和持久化记录现在拒绝 notes: null，同时 update patch 仍保留 null 作为显式清除信号；
• mutation options 现在会拒绝未知字段，因此拼错或多余字段不会再静默关闭 expectedRevision CAS。

回归测试覆盖了真实的契约和 store 边界，并验证 mutation options 被拒绝后，持久化 revision 和 state 都不会变化。目前没有剩余 P0–P3。

Phase 0 的权威边界保持清晰：Core 负责 item contract，Storage 负责持久化 mutation 与 CAS，没有引入 Runtime 执行状态副本或平行 authority。当前方案已经是已批准范围内的最小完整实现，不需要继续重构或拆分 PR。

当前 head 的 Core/Storage build 通过，聚焦测试分别为 15/15 与 18/18，Biome、git diff --check 和 GitHub checks 均通过，merge state 为 clean。

我这边 approve。

Work Board Phase 0

This PR implements the maintainer-approved Phase 0 Work Board contract (see the 7-point review and accepted revision in #2560).

Key points:

• durable Work Board items with no total item cap
• bounded pagination (default 50, max 100)
• explicit todo/in_progress/done lifecycle
• strict provenance union (manual / main_conversation / side_conversation)
• SQLite scope/project invariant
• semantic patch mutation semantics
• monotonic revision + optional expectedRevision CAS
• serialized transactional writes (BEGIN IMMEDIATE)
• archive-before-delete semantics
• active-row partial indexes so default list queries stay bounded under archive-heavy data
• schema 8 -> 9 additive migration
• fail-closed corruption detection

Maintainer-confirmed deferrals (liugddx, #2560):

• linkedSessions moves to Phase 3; Phase 0 rejects the field in create input and stored records
• linked-session projection is deferred to Phase 3; it will be implemented beside the canonical Runtime Host / Desktop continuity adapter against SessionContinuitySnapshot / TurnSnapshot

Intentionally deferred:

• Task Ledger integration
• Runtime Host integration
• model-visible Work Board tools
• recovery/graph state
• resultRefs
• automatic completion

Verification

• core + storage focused tests pass (30 tests)
• @maka/core and @maka/storage build/typecheck
• Biome clean
• migration: v0.1.6 fixture + exact v8 DDL -> real 8->9 path; old schema objects retained; partial indexes present
• archive-heavy list queries covered by EXPLAIN QUERY PLAN regression test against the production query builder
• cross-process CAS covered by a worker-thread test (one winner, one operation_conflict)

Checklist

• Phase 0 contract matches the maintainer-approved scope and deferrals
• Migration is additive (8 -> 9) with no user-data DROP
• Tests updated and passing
• Docs and PR description current

Refs #2560

[Astro-Han]

Thanks for defining the Work Board authority boundary before adding UI or Runtime integration.

Before getting into the implementation details, I think the product scope should be reconciled with the more recent decision in #2290. That discussion deliberately reduced the Session Task Ledger to a narrow Session-local Todo snapshot: no stable item identity, per-item CRUD, hierarchy, evidence, pagination, or workflow UI.

I understand that #2560 describes a different owner: Work Board items are user-owned, cross-Session deferred intentions, while SessionTodo is a model-authored progress snapshot. I am not suggesting that Work Board should reuse SessionTodo or the Task Ledger.

The remaining question is whether this distinct product surface needs a full Work Board domain yet. This PR introduces another durable task-like entity with stable IDs, per-item mutations, scopes, provenance variants, a state machine, archive/delete behavior, pagination, revisions, and future Session links—before there is a UI or production caller. That appears to reintroduce much of the product and maintenance complexity that #2290 has just removed from the existing task system.

Could we first establish why a minimal user-owned Todo list is insufficient for the actual problem of “remember this for later without interrupting the current Session”? A small vertical slice—capture, list, complete, and delete, with optional project/source context—would validate the user need without fixing the larger Board contract in schema v1. Session linking and execution projection could then be added when “start as task” has a real consumer.

If the broader Work Board scope remains intentional after that reconciliation, I found three implementation issues that seem worth resolving before the Phase 0 schema is published:

1. The revision check is outside the SQLite write transaction. Two processes can both read revision 1, both pass expectedRevision: 1, both write revision 2, and the later write silently overwrites the earlier semantic patch. Please make the read/check/write sequence one BEGIN IMMEDIATE transaction, or use conditional UPDATE/DELETE ... WHERE revision = ? statements and treat zero affected rows as a conflict.

2. The linked-session projector validates a new DTO rather than the canonical SessionContinuitySnapshot. It also uses Core TurnStatus, which rejects valid continuity states such as waiting_for_user and cancelled. Since there is no production consumer yet, the simplest option may be to defer this projector until it can live beside the real Runtime Host/Desktop continuity adapter instead of introducing a parallel contract now.

3. The new index does not satisfy the list ordering. The default unscoped query performs a full-table scan and temporary sort, while scoped queries still require a temporary sort for the final key because item_id has the opposite direction. Since the contract intentionally has no total item cap, pagination currently bounds returned rows but not query work. Please align the indexes with the actual scoped/unscoped query shapes before schema v9 is released.

The focused tests and current CI are green. I would also replace the fresh-database “migration” test with a real schema-8 upgrade fixture, but I see that as a verification improvement rather than a separate production finding.

简体中文

感谢你在增加 UI 或 Runtime 集成前，先明确 Work Board 的权威边界。

在讨论具体实现前，我认为这里的产品范围需要先与 #2290 中较新的决定重新对齐。该讨论刚刚把 Session Task Ledger 明确收缩为一个很窄的 Session-local Todo 快照：没有稳定的事项身份、逐项 CRUD、层级、证据、分页或 workflow UI。

我理解 #2560 定义的是另一个 owner：Work Board 是用户拥有的、跨 Session 的暂缓事项；SessionTodo 则是模型写入的进度快照。我并不是建议 Work Board 复用 SessionTodo 或 Task Ledger。

真正需要确认的是：这个独立的产品界面现在是否已经需要一套完整的 Work Board 领域模型。本 PR 在还没有 UI 和生产调用方时，就引入了另一个持久化的 task-like 实体，包括稳定 ID、逐项 mutation、scope、多种 provenance、状态机、归档/删除、分页、revision，以及未来的 Session 关联。这似乎重新引入了 #2290 刚从现有任务系统中删除的大量产品与维护复杂度。

我们是否应该先说明：对于“记住这个后续事项，但不要打断当前 Session”这一真实问题，为什么一个最小的、用户拥有的 Todo 列表还不够？先交付一条较小的纵向链路——保存、列出、完成和删除，并按需携带项目或来源上下文——就可以验证用户需求，而不必现在把更大的 Board contract 固化进 schema v1。等“启动为任务”出现真实消费者时，再增加 Session 关联和执行状态投影也不迟。

如果重新对齐后，完整的 Work Board 范围仍然是有意保留的，我还发现三个建议在发布 Phase 0 schema 前解决的实现问题：

1. revision 检查发生在 SQLite 写事务之外。两个进程可以同时读到 revision 1，都通过 expectedRevision: 1，然后分别写入 revision 2；后写入的 semantic patch 会静默覆盖前一次修改。建议把读取、检查和写入放进同一个 BEGIN IMMEDIATE 事务，或者使用带 WHERE revision = ? 条件的 UPDATE/DELETE，并将影响行数为零视为冲突。

2. linked-session projector 校验的是一套新定义的 DTO，而不是权威的 SessionContinuitySnapshot。它还使用了 Core TurnStatus，因此会拒绝 waiting_for_user、cancelled 等合法的 continuity 状态。当前还没有生产调用方，最简单的方案可能是先推迟这个 projector，等真实的 Runtime Host/Desktop continuity adapter 出现时再贴近实际 owner 实现，避免现在引入一份平行契约。

3. 新增索引不能满足 list 的实际排序。默认的无 scope 查询会全表扫描并临时排序；scoped 查询也会因为 item_id 的索引方向与查询相反，对最后一个排序键进行临时排序。由于契约明确不设置事项总量上限，目前分页只限制了返回行数，并没有限制每页查询的工作量。建议在 schema v9 发布前，让索引与 scoped/unscoped 查询的真实形态一致。

Focused tests 和当前 CI 均已通过。我还建议把“从空数据库创建 v9”的 migration 测试替换成真实的 schema 8 升级 fixture，不过这属于验证改进，不是独立的生产 finding。

1. Revision CAS — update / archive / unarchive / remove now run the full read → revision check → write sequence inside one BEGIN IMMEDIATE transaction. The in-process write queue is retained for process-local serialization; the transaction closes the cross-process race. I confirmed the shared transaction helper flattens the nested #writeItem call, so there is no premature commit.

2. Linked-session projection — work-board-session-projection.ts (module, test, and package export) is removed. It was a parallel DTO validated with Core TurnStatus, which cannot represent waiting_for_user / cancelled from the canonical continuity contract. With no production consumer in Phase 0, I agree the projector should wait until Phase 3 and live beside the real Runtime Host / Desktop continuity adapter.

3. Indexes — schema v9 now ships (scope_kind, project_id, updated_at DESC, item_id DESC) and (updated_at DESC, item_id DESC). I verified against populated data with EXPLAIN QUERY PLAN: the default unscoped query, scoped queries (project and inbox), and both cursor forms use the indexes and no longer perform a full-table scan or temporary sort.

The migration test now builds a real schema-8 database from the released v0.1.6 operational-state fixture plus the exact v8 workflow DDL, then runs the actual 8→9 migration path and checks that the board table exists and the old schema objects remain.

On the product-scope question, I would like to separate PR fidelity from contract re-scoping:

• Fidelity to product(desktop): capture deferred work in a project-aware Work Board #2560: every semantic in this PR maps to the maintainer-approved Phase 0 contract from liugddx's review (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)) and the accepted revision (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)). Most of the surface you listed is load-bearing for that contract: pagination and archive/delete replaced the total-item cap the maintainer removed; revision/CAS was explicitly requested for concurrent renderer writes; provenance variants are required for side-chat capture to survive fork deletion; stable identity is the reference point Phase 3 "start as task" will need.

• RFC: Radically slim the Session Task Ledger #2290's Option 2 governs SessionTodo, not Work Board: the explicit-absent list in RFC: Radically slim the Session Task Ledger #2290 applies to the model-authored, Session-local progress snapshot. Work Board is a different owner (user-owned, cross-Session). Your own acceptance comment in RFC: Radically slim the Session Task Ledger #2290 states that product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 may proceed independently and should not become a P3 integration dependency of RFC: Radically slim the Session Task Ledger #2290 (RFC: Radically slim the Session Task Ledger #2290 (comment)).

The one item I agree has no Phase 0 consumer today is linkedSessions: the field exists in the schema, but Phase 0 has no mutation path that writes it and no UI or runtime caller reads it; Phase 3 "start as task" is the intended consumer. Rather than removing a maintainer-approved field unilaterally, I would like a decision.

@liugddx, could you please confirm:

(a) Does Phase 0 remain the approved contract after #2290 Option 2, or should it be re-scoped to capture / list / complete / delete with optional project and source context?

(b) Should linkedSessions stay in schema v1, or move to Phase 3 via a future additive migration?

(c) Is the linked-session projection formally deferred (removed from the Phase 0 deliverables), or do you want it implemented in Phase 0 against the canonical SessionContinuitySnapshot / TurnSnapshot?

I will not push further commits until these are resolved.

感谢 review。三个实现问题我都已核验并在 476eb218b 修复：

1. Revision CAS：update / archive / unarchive / remove 现在把“读取 → revision 校验 → 写入”完整放进同一个 BEGIN IMMEDIATE 事务。进程内 write queue 保留用于单进程串行化；事务关闭跨进程竞争窗口。我已确认共享事务助手会扁平化嵌套的 #writeItem 调用，不会提前提交。

2. Linked-session projection：work-board-session-projection.ts（模块、测试、package export）已删除。它是一套平行 DTO，用 Core TurnStatus 校验，无法表达 canonical continuity 中的 waiting_for_user / cancelled。Phase 0 没有生产消费者，我同意推迟到 Phase 3，并放到真实 Runtime Host / Desktop continuity adapter 旁边实现。

3. 索引：schema v9 现在包含 (scope_kind, project_id, updated_at DESC, item_id DESC) 和 (updated_at DESC, item_id DESC)。我用真实填充数据跑了 EXPLAIN QUERY PLAN：默认 unscoped 查询、scoped 查询（project 与 inbox）以及两种 cursor 形态都使用索引，不再全表扫描或临时排序。

Migration 测试现在用发布的 v0.1.6 operational-state fixture + 精确的 v8 workflow DDL 构造真实 schema-8 库，走完整 8→9 迁移路径，并断言新表存在、旧 schema 对象保留。

关于产品范围问题，我想把“PR 是否忠实”和“契约是否要重新收缩”分开：

• 对 product(desktop): capture deferred work in a project-aware Work Board #2560 的忠实度：本 PR 的每个 semantic 都能对应 liugddx 的 maintainer review（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294753604）和已接受的修订版（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294956443）。你点名的多数复杂度都是该契约的承重结构：分页和 archive/delete 替代了 maintainer 移除的总上限；revision/CAS 是并发 renderer 写入的明确要求；provenance variants 是 side-chat 捕获在 fork 删除后仍可追溯的验收条件；stable identity 是 Phase 3 “start as task” 需要的引用点。

• RFC: Radically slim the Session Task Ledger #2290 Option 2 约束的是 SessionTodo，不是 Work Board：RFC: Radically slim the Session Task Ledger #2290 的 explicitly-absent 列表针对 model-authored、Session-local 的进度快照。Work Board 是不同的 owner（user-owned、cross-Session）。你在 RFC: Radically slim the Session Task Ledger #2290 的接受评论里也明确写了 product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 可以独立推进，不应成为 RFC: Radically slim the Session Task Ledger #2290 的 P3 集成依赖（https://github.com/maka-agent/maka-agent/issues/2290#issuecomment-5298957426）。

我唯一同意“Phase 0 没有消费者”的是 linkedSessions：字段在 schema 里，但 Phase 0 没有任何 mutation 路径写入它，也没有 UI 或 runtime 调用方读取；Phase 3 “start as task” 才是消费者。与其单方面删除 maintainer 已批准的字段，我希望得到一个明确决定。

@liugddx 能否确认：

(a) #2290 Option 2 之后，Phase 0 是否仍然以已批准契约为准，还是收缩为 capture / list / complete / delete + 可选的 project/source context？

(b) linkedSessions 留在 schema v1，还是移到 Phase 3（未来 additive migration）？

(c) linked-session projection 是否正式推迟（从 Phase 0 交付物移除），还是要求在 Phase 0 基于 canonical SessionContinuitySnapshot / TurnSnapshot 实现？

在得到答复前我不会再 push 新 commit。

[liugddx]

Thanks for addressing Astro-Han's review carefully. I rechecked the updated implementation against the approved #2560 Phase 0 contract and the later #2290 Option 2 boundary.

My maintainer decisions are:

1. Phase 0 remains an independently approved Work Board contract.#2290 Option 2 narrows the model-authored, Session-local SessionTodo; it does not re-scope the user-owned, cross-Session Work Board into the same domain. The broader Phase 0 contract therefore does not need to be reduced to a generic Todo list solely because of #2290.
2. Move linkedSessions to Phase 3. It has no Phase 0 consumer, and it is already exposed as writable input through CreateWorkBoardItemInput and persisted by the create normalizer, so it is not merely a harmless reserved field. An additive migration when “start as task” has a real caller is the smaller and safer compatibility commitment.
3. The linked-session projection is formally deferred to Phase 3. Removing the parallel DTO was correct. Implement it beside the real Runtime Host/Desktop continuity adapter against canonical SessionContinuitySnapshot / TurnSnapshot facts when the consumer exists.

The CAS fix is correct: the read, revision check, and write now share one BEGIN IMMEDIATE transaction. The schema-8 upgrade fixture is also a meaningful improvement.

One implementation issue remains before merge: the index fix removes the temporary sort but does not bound filtering work for the default query. list() adds archived = 0, while neither ordering index contains archived. With an unbounded number of archived rows and few active rows, SQLite may still walk most of the ordering index to produce one active page. EXPLAIN QUERY PLAN reporting an index scan and no temporary B-tree does not disprove that scan cost.

Please add active-row partial indexes for both unscoped and scoped query shapes (or an equivalent design), and cover the archive-heavy case. After removing linkedSessions from the Phase 0 contract/store/tests and closing this remaining query-cost hole, the PR will match the approved authority boundary and be ready for another pass.

简体中文

感谢你认真处理 Astro-Han 的评审。我重新对照了已批准的 #2560 Phase 0 契约和后续 #2290 Option 2 的权威边界。

我的 maintainer 决策如下：

1. Phase 0 继续作为独立批准的 Work Board 契约推进。#2290 Option 2 收缩的是模型写入、Session-local 的 SessionTodo，并没有把用户拥有、跨 Session 的 Work Board 收缩进同一个领域。因此，不能仅因为 #2290 就把完整 Phase 0 再缩成普通 Todo 列表。
2. linkedSessions 移到 Phase 3。 Phase 0 没有消费者，而且它已经通过 CreateWorkBoardItemInput 暴露为可写输入，并由 create normalizer 持久化，所以它并不是一个无害的预留字段。等“启动为任务”出现真实调用方时，通过增量迁移增加，是更小、更安全的兼容性承诺。
3. linked-session projection 正式推迟到 Phase 3。 删除平行 DTO 是正确的。等真实消费者出现时，再放到 Runtime Host/Desktop continuity adapter 旁，基于规范的 SessionContinuitySnapshot / TurnSnapshot 事实实现。

CAS 修复成立：读取、revision 校验和写入现在位于同一个 BEGIN IMMEDIATE 事务中。真实 schema-8 升级 fixture 也是有意义的改进。

合并前还剩一个实现问题：索引修复消除了临时排序，但没有限制默认查询的过滤工作量。list() 会添加 archived = 0，但两个排序索引都不包含 archived。当归档记录无上限、活动记录很少时，SQLite 为返回一页活动事项仍可能遍历排序索引中的大多数记录。EXPLAIN QUERY PLAN 显示使用索引且没有临时 B-tree，并不能证明扫描成本受限。

请为 scoped 和 unscoped 的活动项查询增加 partial indexes（或等价设计），并覆盖“绝大多数记录已归档”的情况。删除 Phase 0 contract/store/tests 中的 linkedSessions，并补齐这个查询成本缺口后，本 PR 就能符合已批准的权威边界，可以进入下一轮评审。

📝 Walkthrough

Summary

• Problem solved

  • Adds the Phase 0 Work Board contract and durable SQLite storage.
  • Supports validated item creation, updates, listing, archiving, restoring, and removal.
  • Adds bounded cursor pagination, provenance checks, lifecycle invariants, semantic patches, and revision-based optimistic concurrency.
  • Detects corrupt records and rejects invalid scope, project, revision, timestamp, and archive data.

• Source of truth

  • Extends the existing packages/core contract and packages/storage SQLite workflow schema.
  • Does not create a parallel linked-session path. linkedSessions and linked-session projection remain deferred to Phase 3.

• Implementation scope

  • Provides the smallest coherent Phase 0 solution.
  • BEGIN IMMEDIATE transactions and the process-local write queue are necessary for serialized mutations and revision checks.
  • Schema migration 8→9 and active, scoped, cursor, and archive indexes support compatibility and query performance.

• Simplification

  • The removed linked-session projection does not reduce Phase 0 behavior or regression coverage.
  • Task Ledger, Runtime Host, model-visible tools, recovery state, result references, and automatic completion remain outside this change.
  • No further deletion or simplification is apparent without weakening behavior or regression coverage.

• Risks and validation

  • Main risks include migration compatibility, concurrent revision conflicts, pagination correctness, SQLite constraint enforcement, timestamp ordering, cursor scope binding, and corrupt-record detection.
  • Tests cover contract behavior, storage operations, worker-thread and cross-process CAS races, pagination, query plans, corruption, constraints, migration, and backup/restore.
  • Reported validation includes passing focused tests, successful builds and typechecks for both packages, and clean Biome checks.
  • Required-check status remains unverified because no direct repository check result is available.

Review-relevant risks

• The PR changes public packages/core and packages/storage exports and adds a durable SQLite schema migration. These are public-contract and release-affecting changes. Material changes in these areas require independent human review under repository policy.
• The PR changes persisted data behavior, including archive-before-delete enforcement, scope/project constraints, migrations, and corruption handling. These changes can affect user data and operational recovery. Material changes in these areas require independent human review under repository policy.
• No security, licensing, or governance effect was identified in the current diff.
• The person performing the merge reviews the final diff. A maintainer makes the final determination.

Thanks for the maintainer decisions. I've applied them in 833481e64:

• linkedSessions is removed from the Phase 0 contract, create input, store, and tests. The Phase 0 normalizer and decoder now reject the field (fail-closed), and the contract doc records it as a Phase 3 addition.
• The linked-session projection stays deferred to Phase 3, documented in the contract and the PR description.
• Active-row partial indexes were added for both default query shapes: workflow_work_board_items_active_order and workflow_work_board_items_active_scope_order (both WHERE archived = 0). The existing full ordering indexes remain for includeArchived queries.
• Archive-heavy coverage: the new storage test creates 120 archived + 6 active items, asserts list behavior, and verifies via EXPLAIN QUERY PLAN that default unscoped and scoped queries use the partial indexes without a temporary sort. The migration test also asserts both partial indexes exist after the 8→9 upgrade.

Verification: core + storage focused tests pass (26 tests), both packages build/typecheck, Biome is clean.

The PR is now ready for review. Let me know if you'd like any further adjustments.

感谢 maintainer 的决定。我已在 833481e64 全部落地：

• linkedSessions 已从 Phase 0 契约、create input、store 和测试中移除；Phase 0 的 normalizer 和 decoder 现在会拒绝该字段（fail-closed），契约文档记录为 Phase 3 加入。
• linked-session projection 保持推迟到 Phase 3，已写入契约文档和 PR description。
• 为两种默认查询形态新增 active-row partial index：workflow_work_board_items_active_order 和 workflow_work_board_items_active_scope_order（均为 WHERE archived = 0）；原有全量排序索引保留给 includeArchived 查询。
• Archive-heavy 覆盖：新增 storage 测试构造 120 条 archived + 6 条 active，断言 list 行为，并用 EXPLAIN QUERY PLAN 验证默认 unscoped/scoped 查询使用 partial index、无临时排序；migration 测试同时断言 8→9 升级后两个 partial index 存在。

验证：core + storage focused tests 全部通过（26 个），两个包 build/typecheck 通过，Biome 干净。

A corrupt row can never be deleted.

remove calls #requireItem, which decodes the row and throws corrupt_record when record_json is unparseable or disagrees with the indexed columns. The fail-closed read is correct, but it also blocks the only removal path. A user who hits a corrupt item cannot repair the board.

Add a repair path. One option is to allow deletion when expectedRevision matches the indexed revision column, without decoding record_json.

The cursor does not bind to the query filters.

encodeCursor stores only updatedAt and itemId. A cursor returned by an inbox-scoped page decodes successfully and applies without complaint to a project-scoped query or to an includeArchived: true query. The caller then receives a page that looks coherent but silently starts from an unrelated position in a different result set.

Include a filter fingerprint in the cursor payload, and reject a cursor whose fingerprint does not match the current query.

Bind the query-plan assertions to the store's own SQL.

The test hand-writes the list SQL. The store builds its list SQL internally. The assertions therefore prove only that the indexes serve this copy of the query. If the store query later changes its filter shape, ORDER BY, or limit, this test stays green while the production path falls back to a scan or a temp sort.

packages/core/src/work-board.ts:494

• Unarchive can currently decrease updatedAt if now is earlier than the stored updatedAt (e.g. wall clock skew). Because list ordering/pagination uses updatedAt, clamp this to keep timestamps monotonic (see e.g. sqlite-long-term-memory-store.ts:953).

 item: {
...activeFields,
archived: false,
updatedAt: now,
revision: item.revision + 1,
},

packages/core/src/work-board.ts:476

• Archive timestamps should be monotonic even if the wall clock moves backwards; otherwise an archive mutation can decrease updatedAt and break ordering/pagination. Consider clamping both archivedAt and updatedAt to at least the current item.updatedAt (consistent with other storage authorities).

 ...item,
archived: true,
archivedAt: now,
updatedAt: now,
revision: item.revision + 1,

packages/core/src/work-board.ts:460

• updatedAt can move backwards if the caller clock moves backwards (or a test/consumer passes an older now). Since list pagination/orders are keyed on updatedAt, a decreasing timestamp can cause incorrect ordering and cursor paging anomalies. Other stores clamp mutation timestamps to be monotonic (e.g. packages/storage/src/sqlite-long-term-memory-store.ts:953, packages/storage/src/managed-secret-store.ts:430-432).

This issue also appears in the following locations of the same file:

 ...(notes === undefined ? {} : { notes }),
scope,

Thanks for working through the earlier review rounds. I rechecked the current head, including the Core contract, SQLite lifecycle, migration, indexes, existing feedback, and focused store tests. The earlier CAS, linked-session projection, indexing, notes-patch, and migration-fixture findings are resolved.

I left three inline P2 comments covering exact-shape validation, monotonic mutation timestamps, and cursor/filter binding. None is a P0/P1, and I do not think this needs a broader redesign or PR split.

Two non-blocking test-truth follow-ups:

• The concurrent-mutation test uses one store, so it proves process-local serialization but would still pass without the cross-process BEGIN IMMEDIATE fix. I would keep it and name it accordingly; a worker/barrier test can cover cross-process CAS if that guarantee needs executable protection.
• The query-plan test is valuable, but it explains a handwritten copy of the list SQL rather than the SQL produced by list(). Sharing an internal query builder would keep the regression test tied to production without adding a public API.

I would keep the remaining contract, persistence, migration, archive, backup, and index tests; they cover distinct lifecycle seams rather than duplicating one another. Overall, the Work Board / SessionTodo authority split is sound, and the current Phase 0 scope is appropriately reduced.

中文对照

感谢持续处理前几轮 review。我重新检查了当前 head，包括 Core 契约、SQLite 生命周期、migration、索引、已有反馈和聚焦的 store 测试。之前的 CAS、linked-session projection、索引、notes patch 和 migration fixture 问题都已经解决。

我留下了三条 inline P2，分别涉及：

• 对 Work Board item 和 mutation input 进行 exact-shape 校验，避免未知字段被静默接受或在下一次写入时丢失；
• 在持久化事务中保持 mutation timestamp 单调，避免系统时钟回拨破坏 keyset pagination；
• 将 opaque cursor 与规范化后的 scope / includeArchived filters 绑定，避免跨结果集复用时静默漏项。

它们都不是 P0/P1，也不需要扩大成整体重构或拆分 PR。

另外有两项非阻塞的测试真实性建议：

• 当前并发 mutation 测试使用同一个 store，因此证明的是进程内串行化；即使没有跨进程 BEGIN IMMEDIATE 修复，它仍会通过。建议保留并让测试名称准确表达该范围；如需可执行地保护跨进程 CAS，再补 worker/barrier 测试。
• Query-plan 测试有价值，但它解释的是手写的 list SQL 副本，而不是 list() 实际生成的 SQL。共享内部 query builder 可以防止测试与生产查询逐渐漂移，同时不需要扩大公共 API。

其余 contract、persistence、migration、archive、backup 和 index 测试覆盖不同生命周期，不建议删除。总体而言，Work Board 与 SessionTodo 的权威边界正确，Phase 0 的当前范围也已经合理收缩。

AI-assisted review disclosure: Codex performed the primary lifecycle review and executable reproductions; three independent Codex reviewers covered contract scope, SQLite behavior, and test truthfulness; Claude performed a focused adversarial adjudication. The final findings were verified against the current PR head.

packages/storage/src/work-board-store.ts:358

• workBoardFilterFingerprint embeds the full projectId (max 160 chars) into filterFingerprint, but decodeCursor rejects fingerprints longer than 128 and the contract bounds cursor strings to 256 chars. For long project IDs this will produce an overlong cursor (and/or an undecodable cursor), causing pagination to fail after the first page with "cursor does not match the list filters".

@somewan820 Verified.

• The cursor test now confirms that the second page has a different item ID.
• WorkBoardStore.list() and the query-plan test both use buildWorkBoardListStatement.
• The migration guard returns before migrateSqliteWorkflowDatabase on a current target schema. The DROP INDEX does not run on normal opens.

The remaining implementation findings are addressed. The index-rebuild finding remains withdrawn.

Learning: In `packages/storage/src/sqlite-workflow-schema.ts`, `migrateSqliteWorkflowDatabase` intentionally drops and recreates `workflow_work_board_items_scope_order`. An intermediate Phase 0 development build created the same index name with `item_id ASC` while registering schema version 9. `inspectAndMigrateOperationalState` only runs this migration when the schema registry or target schema does not match, so the drop executes only during migration. SQLite `CREATE INDEX IF NOT EXISTS` cannot replace the old same-name index definition.

packages/storage/src/tests/work-board-store.test.ts:352

• This test name says “cross-process”, but it uses Worker from node:worker_threads, which is cross-thread (same process) rather than cross-process. Either rename the test to match what it actually exercises, or switch to a child-process based worker if you truly need a cross-process regression.

• If you keep using worker threads here, process.pid is the same across all workers, which makes the “winner” update harder to distinguish when debugging. Importing and using threadId gives each worker a unique identifier within the process.

Follow-up: I reviewed the current head (688051767). The requested Phase 0 scope changes, active-row partial indexes with archive-heavy coverage, and Astro-Han’s subsequent P2 findings are resolved. The remaining test-truth caveat is non-blocking. This PR is ready to merge.

[liugddx]

Approved. The current head satisfies the approved Phase 0 contract and resolves the outstanding review findings.

[Astro-Han]

Thanks for carrying the earlier review rounds through to a coherent Phase 0 boundary. I rechecked the current head after the maintainer approval, including the Core contract, SQLite lifecycle, migration/index paths, prior feedback, and focused tests.

The previous CAS transaction, linked-session deferral, active-row indexes, monotonic mutation timestamps, filter-bound cursors, and cursor-size fixes all hold. I found two remaining runtime-boundary gaps and left them inline:

• create/stored notes still accepts null even though that clear signal belongs only to update patches;
• unknown mutation-option keys can silently disable expectedRevision CAS.

Both are narrow exact-validation fixes at the existing owners. They do not call for reopening the product scope, redesigning the store, or splitting this PR.

Focused verification on 688051767:

• @maka/core build: passed
• @maka/storage build: passed
• Work Board storage test file: 17/17 passed
• visible GitHub checks: green

Once the two inline issues are addressed, this should only need a quick final pass.

中文版

感谢把前几轮 review 收敛成连贯的 Phase 0 边界。我在 maintainer Approve 之后重新检查了同一个当前 head，包括 Core 契约、SQLite 生命周期、migration/index、已有反馈和聚焦测试。

此前的 CAS 事务、linked-session 推迟、active partial indexes、mutation 时间戳单调性、游标与过滤条件绑定，以及游标长度问题都已经正确解决。

目前还剩两个运行时边界缺口，已分别留下 inline comment：create/持久化记录仍会接受 notes: null；mutation options 的未知字段可能静默关闭 expectedRevision CAS。两者都只需要在现有 owner 上补齐精确校验，不需要重新讨论产品范围、重构 store 或拆分 PR。

当前 head 的 Core/Storage 构建通过，Work Board storage 聚焦测试 17/17 通过，GitHub 可见检查全绿。处理完两条 inline 后，快速复核即可。

Astro-Han — both P2 inline comments are fixed in cbf2dc64a (details in the threads):

• notes: null is now rejected in create input and stored records; null remains the explicit clear signal only in update patches.
• Mutation options are validated as an exact-shape object, so unknown keys like expectedRevison or extra fields throw invalid_input instead of silently disabling expectedRevision CAS.

Verification: core + storage focused tests pass (33 tests), both packages build/typecheck, Biome clean. liugddx already approved the prior head; the new commit only contains these two narrow validation fixes.

Could you take the quick final pass? If everything looks good, this PR is ready to merge. @liugddx — happy to merge once Astro-Han confirms.

简体中文

Astro-Han —— 两条 P2 代码评论已在 cbf2dc64a 修复（详见对应线程）：

• create input 和已存记录现在拒绝 notes: null；null 只保留为 update patch 的显式清除信号。
• mutation options 改为精确形状校验，expectedRevison 这类拼写错误或多余字段会直接 invalid_input，不会再静默关闭 expectedRevision CAS。

验证：core + storage focused tests 全部通过（33 个），两个包 build/typecheck 通过，Biome 干净。liugddx 已对前一版 head 表示 approve；本次新 commit 只包含这两处窄校验修复。

能否做最后一次快速复核？如果没问题，这个 PR 就可以合并了。@liugddx —— Astro-Han 确认后就可以 merge。

[Astro-Han]

Thanks for the quick follow-up. I rechecked the current head (cbf2dc64a) and both remaining P2 findings are resolved:

• create input and durable records now reject notes: null, while update patches retain null as the explicit clear signal;
• mutation options now fail closed on unknown keys, so a misspelled or extra field cannot silently disable expectedRevision CAS.

The regression tests exercise the real contract/store boundaries and verify that rejected mutation options leave the stored revision and state unchanged. I found no remaining P0–P3 issues.

The Phase 0 authority boundary remains intact: Core owns the item contract, Storage owns durable mutation and CAS, and no Runtime execution state or parallel authority has been introduced. The current solution is the smallest complete implementation of the approved scope; it does not need further restructuring or a PR split.

Verification on cbf2dc64a:

• @maka/core build and focused Work Board tests: 15/15 passed
• @maka/storage build and focused Work Board tests: 18/18 passed
• Biome formatting check on the four changed files: passed
• git diff --check: passed
• visible GitHub checks: green
• merge state: clean

Approved from my side.

感谢快速处理。我重新检查了当前 head（cbf2dc64a），最后两条 P2 都已解决：

• create input 和持久化记录现在拒绝 notes: null，同时 update patch 仍保留 null 作为显式清除信号；
• mutation options 现在会拒绝未知字段，因此拼错或多余字段不会再静默关闭 expectedRevision CAS。

回归测试覆盖了真实的契约和 store 边界，并验证 mutation options 被拒绝后，持久化 revision 和 state 都不会变化。目前没有剩余 P0–P3。

Phase 0 的权威边界保持清晰：Core 负责 item contract，Storage 负责持久化 mutation 与 CAS，没有引入 Runtime 执行状态副本或平行 authority。当前方案已经是已批准范围内的最小完整实现，不需要继续重构或拆分 PR。

当前 head 的 Core/Storage build 通过，聚焦测试分别为 15/15 与 18/18，Biome、git diff --check 和 GitHub checks 均通过，merge state 为 clean。

我这边 approve。

Work Board Phase 0

This PR implements the maintainer-approved Phase 0 Work Board contract (see the 7-point review and accepted revision in #2560).

Key points:

• durable Work Board items with no total item cap
• bounded pagination (default 50, max 100)
• explicit todo/in_progress/done lifecycle
• strict provenance union (manual / main_conversation / side_conversation)
• SQLite scope/project invariant
• semantic patch mutation semantics
• monotonic revision + optional expectedRevision CAS
• serialized transactional writes (BEGIN IMMEDIATE)
• archive-before-delete semantics
• active-row partial indexes so default list queries stay bounded under archive-heavy data
• schema 8 -> 9 additive migration
• fail-closed corruption detection

Maintainer-confirmed deferrals (liugddx, #2560):

• linkedSessions moves to Phase 3; Phase 0 rejects the field in create input and stored records
• linked-session projection is deferred to Phase 3; it will be implemented beside the canonical Runtime Host / Desktop continuity adapter against SessionContinuitySnapshot / TurnSnapshot

Intentionally deferred:

• Task Ledger integration
• Runtime Host integration
• model-visible Work Board tools
• recovery/graph state
• resultRefs
• automatic completion

Verification

• core + storage focused tests pass (30 tests)
• @maka/core and @maka/storage build/typecheck
• Biome clean
• migration: v0.1.6 fixture + exact v8 DDL -> real 8->9 path; old schema objects retained; partial indexes present
• archive-heavy list queries covered by EXPLAIN QUERY PLAN regression test against the production query builder
• cross-process CAS covered by a worker-thread test (one winner, one operation_conflict)

Checklist

• Phase 0 contract matches the maintainer-approved scope and deferrals
• Migration is additive (8 -> 9) with no user-data DROP
• Tests updated and passing
• Docs and PR description current

Refs #2560

[Astro-Han]

Thanks for defining the Work Board authority boundary before adding UI or Runtime integration.

Before getting into the implementation details, I think the product scope should be reconciled with the more recent decision in #2290. That discussion deliberately reduced the Session Task Ledger to a narrow Session-local Todo snapshot: no stable item identity, per-item CRUD, hierarchy, evidence, pagination, or workflow UI.

I understand that #2560 describes a different owner: Work Board items are user-owned, cross-Session deferred intentions, while SessionTodo is a model-authored progress snapshot. I am not suggesting that Work Board should reuse SessionTodo or the Task Ledger.

The remaining question is whether this distinct product surface needs a full Work Board domain yet. This PR introduces another durable task-like entity with stable IDs, per-item mutations, scopes, provenance variants, a state machine, archive/delete behavior, pagination, revisions, and future Session links—before there is a UI or production caller. That appears to reintroduce much of the product and maintenance complexity that #2290 has just removed from the existing task system.

Could we first establish why a minimal user-owned Todo list is insufficient for the actual problem of “remember this for later without interrupting the current Session”? A small vertical slice—capture, list, complete, and delete, with optional project/source context—would validate the user need without fixing the larger Board contract in schema v1. Session linking and execution projection could then be added when “start as task” has a real consumer.

If the broader Work Board scope remains intentional after that reconciliation, I found three implementation issues that seem worth resolving before the Phase 0 schema is published:

1. The revision check is outside the SQLite write transaction. Two processes can both read revision 1, both pass expectedRevision: 1, both write revision 2, and the later write silently overwrites the earlier semantic patch. Please make the read/check/write sequence one BEGIN IMMEDIATE transaction, or use conditional UPDATE/DELETE ... WHERE revision = ? statements and treat zero affected rows as a conflict.

2. The linked-session projector validates a new DTO rather than the canonical SessionContinuitySnapshot. It also uses Core TurnStatus, which rejects valid continuity states such as waiting_for_user and cancelled. Since there is no production consumer yet, the simplest option may be to defer this projector until it can live beside the real Runtime Host/Desktop continuity adapter instead of introducing a parallel contract now.

3. The new index does not satisfy the list ordering. The default unscoped query performs a full-table scan and temporary sort, while scoped queries still require a temporary sort for the final key because item_id has the opposite direction. Since the contract intentionally has no total item cap, pagination currently bounds returned rows but not query work. Please align the indexes with the actual scoped/unscoped query shapes before schema v9 is released.

The focused tests and current CI are green. I would also replace the fresh-database “migration” test with a real schema-8 upgrade fixture, but I see that as a verification improvement rather than a separate production finding.

简体中文

感谢你在增加 UI 或 Runtime 集成前，先明确 Work Board 的权威边界。

在讨论具体实现前，我认为这里的产品范围需要先与 #2290 中较新的决定重新对齐。该讨论刚刚把 Session Task Ledger 明确收缩为一个很窄的 Session-local Todo 快照：没有稳定的事项身份、逐项 CRUD、层级、证据、分页或 workflow UI。

我理解 #2560 定义的是另一个 owner：Work Board 是用户拥有的、跨 Session 的暂缓事项；SessionTodo 则是模型写入的进度快照。我并不是建议 Work Board 复用 SessionTodo 或 Task Ledger。

真正需要确认的是：这个独立的产品界面现在是否已经需要一套完整的 Work Board 领域模型。本 PR 在还没有 UI 和生产调用方时，就引入了另一个持久化的 task-like 实体，包括稳定 ID、逐项 mutation、scope、多种 provenance、状态机、归档/删除、分页、revision，以及未来的 Session 关联。这似乎重新引入了 #2290 刚从现有任务系统中删除的大量产品与维护复杂度。

我们是否应该先说明：对于“记住这个后续事项，但不要打断当前 Session”这一真实问题，为什么一个最小的、用户拥有的 Todo 列表还不够？先交付一条较小的纵向链路——保存、列出、完成和删除，并按需携带项目或来源上下文——就可以验证用户需求，而不必现在把更大的 Board contract 固化进 schema v1。等“启动为任务”出现真实消费者时，再增加 Session 关联和执行状态投影也不迟。

如果重新对齐后，完整的 Work Board 范围仍然是有意保留的，我还发现三个建议在发布 Phase 0 schema 前解决的实现问题：

1. revision 检查发生在 SQLite 写事务之外。两个进程可以同时读到 revision 1，都通过 expectedRevision: 1，然后分别写入 revision 2；后写入的 semantic patch 会静默覆盖前一次修改。建议把读取、检查和写入放进同一个 BEGIN IMMEDIATE 事务，或者使用带 WHERE revision = ? 条件的 UPDATE/DELETE，并将影响行数为零视为冲突。

2. linked-session projector 校验的是一套新定义的 DTO，而不是权威的 SessionContinuitySnapshot。它还使用了 Core TurnStatus，因此会拒绝 waiting_for_user、cancelled 等合法的 continuity 状态。当前还没有生产调用方，最简单的方案可能是先推迟这个 projector，等真实的 Runtime Host/Desktop continuity adapter 出现时再贴近实际 owner 实现，避免现在引入一份平行契约。

3. 新增索引不能满足 list 的实际排序。默认的无 scope 查询会全表扫描并临时排序；scoped 查询也会因为 item_id 的索引方向与查询相反，对最后一个排序键进行临时排序。由于契约明确不设置事项总量上限，目前分页只限制了返回行数，并没有限制每页查询的工作量。建议在 schema v9 发布前，让索引与 scoped/unscoped 查询的真实形态一致。

Focused tests 和当前 CI 均已通过。我还建议把“从空数据库创建 v9”的 migration 测试替换成真实的 schema 8 升级 fixture，不过这属于验证改进，不是独立的生产 finding。

AI-assisted review disclosure: Codex and Claude Opus were used to inspect the change and challenge the findings. I reproduced and adjudicated the issues above against the current source and own this review.

[somewan820]

Thanks for the review. I have verified all three implementation findings and fixed them in 476eb218b:

1. Revision CAS — update / archive / unarchive / remove now run the full read → revision check → write sequence inside one BEGIN IMMEDIATE transaction. The in-process write queue is retained for process-local serialization; the transaction closes the cross-process race. I confirmed the shared transaction helper flattens the nested #writeItem call, so there is no premature commit.

2. Linked-session projection — work-board-session-projection.ts (module, test, and package export) is removed. It was a parallel DTO validated with Core TurnStatus, which cannot represent waiting_for_user / cancelled from the canonical continuity contract. With no production consumer in Phase 0, I agree the projector should wait until Phase 3 and live beside the real Runtime Host / Desktop continuity adapter.

3. Indexes — schema v9 now ships (scope_kind, project_id, updated_at DESC, item_id DESC) and (updated_at DESC, item_id DESC). I verified against populated data with EXPLAIN QUERY PLAN: the default unscoped query, scoped queries (project and inbox), and both cursor forms use the indexes and no longer perform a full-table scan or temporary sort.

The migration test now builds a real schema-8 database from the released v0.1.6 operational-state fixture plus the exact v8 workflow DDL, then runs the actual 8→9 migration path and checks that the board table exists and the old schema objects remain.

On the product-scope question, I would like to separate PR fidelity from contract re-scoping:

• Fidelity to product(desktop): capture deferred work in a project-aware Work Board #2560: every semantic in this PR maps to the maintainer-approved Phase 0 contract from liugddx's review (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)) and the accepted revision (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)). Most of the surface you listed is load-bearing for that contract: pagination and archive/delete replaced the total-item cap the maintainer removed; revision/CAS was explicitly requested for concurrent renderer writes; provenance variants are required for side-chat capture to survive fork deletion; stable identity is the reference point Phase 3 "start as task" will need.

• RFC: Radically slim the Session Task Ledger #2290's Option 2 governs SessionTodo, not Work Board: the explicit-absent list in RFC: Radically slim the Session Task Ledger #2290 applies to the model-authored, Session-local progress snapshot. Work Board is a different owner (user-owned, cross-Session). Your own acceptance comment in RFC: Radically slim the Session Task Ledger #2290 states that product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 may proceed independently and should not become a P3 integration dependency of RFC: Radically slim the Session Task Ledger #2290 (RFC: Radically slim the Session Task Ledger #2290 (comment)).

The one item I agree has no Phase 0 consumer today is linkedSessions: the field exists in the schema, but Phase 0 has no mutation path that writes it and no UI or runtime caller reads it; Phase 3 "start as task" is the intended consumer. Rather than removing a maintainer-approved field unilaterally, I would like a decision.

@liugddx, could you please confirm:

(a) Does Phase 0 remain the approved contract after #2290 Option 2, or should it be re-scoped to capture / list / complete / delete with optional project and source context?

(b) Should linkedSessions stay in schema v1, or move to Phase 3 via a future additive migration?

(c) Is the linked-session projection formally deferred (removed from the Phase 0 deliverables), or do you want it implemented in Phase 0 against the canonical SessionContinuitySnapshot / TurnSnapshot?

I will not push further commits until these are resolved.

感谢 review。三个实现问题我都已核验并在 476eb218b 修复：

1. Revision CAS：update / archive / unarchive / remove 现在把“读取 → revision 校验 → 写入”完整放进同一个 BEGIN IMMEDIATE 事务。进程内 write queue 保留用于单进程串行化；事务关闭跨进程竞争窗口。我已确认共享事务助手会扁平化嵌套的 #writeItem 调用，不会提前提交。

2. Linked-session projection：work-board-session-projection.ts（模块、测试、package export）已删除。它是一套平行 DTO，用 Core TurnStatus 校验，无法表达 canonical continuity 中的 waiting_for_user / cancelled。Phase 0 没有生产消费者，我同意推迟到 Phase 3，并放到真实 Runtime Host / Desktop continuity adapter 旁边实现。

3. 索引：schema v9 现在包含 (scope_kind, project_id, updated_at DESC, item_id DESC) 和 (updated_at DESC, item_id DESC)。我用真实填充数据跑了 EXPLAIN QUERY PLAN：默认 unscoped 查询、scoped 查询（project 与 inbox）以及两种 cursor 形态都使用索引，不再全表扫描或临时排序。

Migration 测试现在用发布的 v0.1.6 operational-state fixture + 精确的 v8 workflow DDL 构造真实 schema-8 库，走完整 8→9 迁移路径，并断言新表存在、旧 schema 对象保留。

关于产品范围问题，我想把“PR 是否忠实”和“契约是否要重新收缩”分开：

• 对 product(desktop): capture deferred work in a project-aware Work Board #2560 的忠实度：本 PR 的每个 semantic 都能对应 liugddx 的 maintainer review（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294753604）和已接受的修订版（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294956443）。你点名的多数复杂度都是该契约的承重结构：分页和 archive/delete 替代了 maintainer 移除的总上限；revision/CAS 是并发 renderer 写入的明确要求；provenance variants 是 side-chat 捕获在 fork 删除后仍可追溯的验收条件；stable identity 是 Phase 3 “start as task” 需要的引用点。

• RFC: Radically slim the Session Task Ledger #2290 Option 2 约束的是 SessionTodo，不是 Work Board：RFC: Radically slim the Session Task Ledger #2290 的 explicitly-absent 列表针对 model-authored、Session-local 的进度快照。Work Board 是不同的 owner（user-owned、cross-Session）。你在 RFC: Radically slim the Session Task Ledger #2290 的接受评论里也明确写了 product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 可以独立推进，不应成为 RFC: Radically slim the Session Task Ledger #2290 的 P3 集成依赖（https://github.com/maka-agent/maka-agent/issues/2290#issuecomment-5298957426）。

我唯一同意“Phase 0 没有消费者”的是 linkedSessions：字段在 schema 里，但 Phase 0 没有任何 mutation 路径写入它，也没有 UI 或 runtime 调用方读取；Phase 3 “start as task” 才是消费者。与其单方面删除 maintainer 已批准的字段，我希望得到一个明确决定。

@liugddx 能否确认：

(a) #2290 Option 2 之后，Phase 0 是否仍然以已批准契约为准，还是收缩为 capture / list / complete / delete + 可选的 project/source context？

(b) linkedSessions 留在 schema v1，还是移到 Phase 3（未来 additive migration）？

(c) linked-session projection 是否正式推迟（从 Phase 0 交付物移除），还是要求在 Phase 0 基于 canonical SessionContinuitySnapshot / TurnSnapshot 实现？

在得到答复前我不会再 push 新 commit。

[liugddx]

Thanks for addressing Astro-Han's review carefully. I rechecked the updated implementation against the approved #2560 Phase 0 contract and the later #2290 Option 2 boundary.

My maintainer decisions are:

1. Phase 0 remains an independently approved Work Board contract.#2290 Option 2 narrows the model-authored, Session-local SessionTodo; it does not re-scope the user-owned, cross-Session Work Board into the same domain. The broader Phase 0 contract therefore does not need to be reduced to a generic Todo list solely because of #2290.
2. Move linkedSessions to Phase 3. It has no Phase 0 consumer, and it is already exposed as writable input through CreateWorkBoardItemInput and persisted by the create normalizer, so it is not merely a harmless reserved field. An additive migration when “start as task” has a real caller is the smaller and safer compatibility commitment.
3. The linked-session projection is formally deferred to Phase 3. Removing the parallel DTO was correct. Implement it beside the real Runtime Host/Desktop continuity adapter against canonical SessionContinuitySnapshot / TurnSnapshot facts when the consumer exists.

The CAS fix is correct: the read, revision check, and write now share one BEGIN IMMEDIATE transaction. The schema-8 upgrade fixture is also a meaningful improvement.

One implementation issue remains before merge: the index fix removes the temporary sort but does not bound filtering work for the default query. list() adds archived = 0, while neither ordering index contains archived. With an unbounded number of archived rows and few active rows, SQLite may still walk most of the ordering index to produce one active page. EXPLAIN QUERY PLAN reporting an index scan and no temporary B-tree does not disprove that scan cost.

Please add active-row partial indexes for both unscoped and scoped query shapes (or an equivalent design), and cover the archive-heavy case. After removing linkedSessions from the Phase 0 contract/store/tests and closing this remaining query-cost hole, the PR will match the approved authority boundary and be ready for another pass.

简体中文

感谢你认真处理 Astro-Han 的评审。我重新对照了已批准的 #2560 Phase 0 契约和后续 #2290 Option 2 的权威边界。

我的 maintainer 决策如下：

1. Phase 0 继续作为独立批准的 Work Board 契约推进。#2290 Option 2 收缩的是模型写入、Session-local 的 SessionTodo，并没有把用户拥有、跨 Session 的 Work Board 收缩进同一个领域。因此，不能仅因为 #2290 就把完整 Phase 0 再缩成普通 Todo 列表。
2. linkedSessions 移到 Phase 3。 Phase 0 没有消费者，而且它已经通过 CreateWorkBoardItemInput 暴露为可写输入，并由 create normalizer 持久化，所以它并不是一个无害的预留字段。等“启动为任务”出现真实调用方时，通过增量迁移增加，是更小、更安全的兼容性承诺。
3. linked-session projection 正式推迟到 Phase 3。 删除平行 DTO 是正确的。等真实消费者出现时，再放到 Runtime Host/Desktop continuity adapter 旁，基于规范的 SessionContinuitySnapshot / TurnSnapshot 事实实现。

CAS 修复成立：读取、revision 校验和写入现在位于同一个 BEGIN IMMEDIATE 事务中。真实 schema-8 升级 fixture 也是有意义的改进。

合并前还剩一个实现问题：索引修复消除了临时排序，但没有限制默认查询的过滤工作量。list() 会添加 archived = 0，但两个排序索引都不包含 archived。当归档记录无上限、活动记录很少时，SQLite 为返回一页活动事项仍可能遍历排序索引中的大多数记录。EXPLAIN QUERY PLAN 显示使用索引且没有临时 B-tree，并不能证明扫描成本受限。

请为 scoped 和 unscoped 的活动项查询增加 partial indexes（或等价设计），并覆盖“绝大多数记录已归档”的情况。删除 Phase 0 contract/store/tests 中的 linkedSessions，并补齐这个查询成本缺口后，本 PR 就能符合已批准的权威边界，可以进入下一轮评审。

📝 Walkthrough

Summary

• Problem solved

  • Adds the Phase 0 Work Board contract and durable SQLite storage.
  • Supports validated item creation, updates, listing, archiving, restoring, and removal.
  • Adds bounded cursor pagination, provenance checks, lifecycle invariants, semantic patches, and revision-based optimistic concurrency.
  • Detects corrupt records and rejects invalid scope, project, revision, timestamp, and archive data.

• Source of truth

  • Extends the existing packages/core contract and packages/storage SQLite workflow schema.
  • Does not create a parallel linked-session path. linkedSessions and linked-session projection remain deferred to Phase 3.

• Implementation scope

  • Provides the smallest coherent Phase 0 solution.
  • BEGIN IMMEDIATE transactions and the process-local write queue are necessary for serialized mutations and revision checks.
  • Schema migration 8→9 and active, scoped, cursor, and archive indexes support compatibility and query performance.

• Simplification

  • The removed linked-session projection does not reduce Phase 0 behavior or regression coverage.
  • Task Ledger, Runtime Host, model-visible tools, recovery state, result references, and automatic completion remain outside this change.
  • No further deletion or simplification is apparent without weakening behavior or regression coverage.

• Risks and validation

  • Main risks include migration compatibility, concurrent revision conflicts, pagination correctness, SQLite constraint enforcement, timestamp ordering, cursor scope binding, and corrupt-record detection.
  • Tests cover contract behavior, storage operations, worker-thread and cross-process CAS races, pagination, query plans, corruption, constraints, migration, and backup/restore.
  • Reported validation includes passing focused tests, successful builds and typechecks for both packages, and clean Biome checks.
  • Required-check status remains unverified because no direct repository check result is available.

Review-relevant risks

• The PR changes public packages/core and packages/storage exports and adds a durable SQLite schema migration. These are public-contract and release-affecting changes. Material changes in these areas require independent human review under repository policy.
• The PR changes persisted data behavior, including archive-before-delete enforcement, scope/project constraints, migrations, and corruption handling. These changes can affect user data and operational recovery. Material changes in these areas require independent human review under repository policy.
• No security, licensing, or governance effect was identified in the current diff.
• The person performing the merge reviews the final diff. A maintainer makes the final determination.

Thanks for the maintainer decisions. I've applied them in 833481e64:

• linkedSessions is removed from the Phase 0 contract, create input, store, and tests. The Phase 0 normalizer and decoder now reject the field (fail-closed), and the contract doc records it as a Phase 3 addition.
• The linked-session projection stays deferred to Phase 3, documented in the contract and the PR description.
• Active-row partial indexes were added for both default query shapes: workflow_work_board_items_active_order and workflow_work_board_items_active_scope_order (both WHERE archived = 0). The existing full ordering indexes remain for includeArchived queries.
• Archive-heavy coverage: the new storage test creates 120 archived + 6 active items, asserts list behavior, and verifies via EXPLAIN QUERY PLAN that default unscoped and scoped queries use the partial indexes without a temporary sort. The migration test also asserts both partial indexes exist after the 8→9 upgrade.

Verification: core + storage focused tests pass (26 tests), both packages build/typecheck, Biome is clean.

The PR is now ready for review. Let me know if you'd like any further adjustments.

感谢 maintainer 的决定。我已在 833481e64 全部落地：

• linkedSessions 已从 Phase 0 契约、create input、store 和测试中移除；Phase 0 的 normalizer 和 decoder 现在会拒绝该字段（fail-closed），契约文档记录为 Phase 3 加入。
• linked-session projection 保持推迟到 Phase 3，已写入契约文档和 PR description。
• 为两种默认查询形态新增 active-row partial index：workflow_work_board_items_active_order 和 workflow_work_board_items_active_scope_order（均为 WHERE archived = 0）；原有全量排序索引保留给 includeArchived 查询。
• Archive-heavy 覆盖：新增 storage 测试构造 120 条 archived + 6 条 active，断言 list 行为，并用 EXPLAIN QUERY PLAN 验证默认 unscoped/scoped 查询使用 partial index、无临时排序；migration 测试同时断言 8→9 升级后两个 partial index 存在。

验证：core + storage focused tests 全部通过（26 个），两个包 build/typecheck 通过，Biome 干净。

A corrupt row can never be deleted.

remove calls #requireItem, which decodes the row and throws corrupt_record when record_json is unparseable or disagrees with the indexed columns. The fail-closed read is correct, but it also blocks the only removal path. A user who hits a corrupt item cannot repair the board.

Add a repair path. One option is to allow deletion when expectedRevision matches the indexed revision column, without decoding record_json.

The cursor does not bind to the query filters.

encodeCursor stores only updatedAt and itemId. A cursor returned by an inbox-scoped page decodes successfully and applies without complaint to a project-scoped query or to an includeArchived: true query. The caller then receives a page that looks coherent but silently starts from an unrelated position in a different result set.

Include a filter fingerprint in the cursor payload, and reject a cursor whose fingerprint does not match the current query.

Bind the query-plan assertions to the store's own SQL.

The test hand-writes the list SQL. The store builds its list SQL internally. The assertions therefore prove only that the indexes serve this copy of the query. If the store query later changes its filter shape, ORDER BY, or limit, this test stays green while the production path falls back to a scan or a temp sort.

Export the query text (or a small explainListPlan helper) from work-board-store.ts and assert the plan for that exact string.

packages/core/src/work-board.ts:494

• Unarchive can currently decrease updatedAt if now is earlier than the stored updatedAt (e.g. wall clock skew). Because list ordering/pagination uses updatedAt, clamp this to keep timestamps monotonic (see e.g. sqlite-long-term-memory-store.ts:953).

 item: {
...activeFields,
archived: false,
updatedAt: now,
revision: item.revision + 1,
},

packages/core/src/work-board.ts:476

• Archive timestamps should be monotonic even if the wall clock moves backwards; otherwise an archive mutation can decrease updatedAt and break ordering/pagination. Consider clamping both archivedAt and updatedAt to at least the current item.updatedAt (consistent with other storage authorities).

 ...item,
archived: true,
archivedAt: now,
updatedAt: now,
revision: item.revision + 1,

packages/core/src/work-board.ts:460

• updatedAt can move backwards if the caller clock moves backwards (or a test/consumer passes an older now). Since list pagination/orders are keyed on updatedAt, a decreasing timestamp can cause incorrect ordering and cursor paging anomalies. Other stores clamp mutation timestamps to be monotonic (e.g. packages/storage/src/sqlite-long-term-memory-store.ts:953, packages/storage/src/managed-secret-store.ts:430-432).

This issue also appears in the following locations of the same file:

 ...(notes === undefined ? {} : { notes }),
scope,

updatedAt: now,
revision: item.revision + 1,

Thanks for working through the earlier review rounds. I rechecked the current head, including the Core contract, SQLite lifecycle, migration, indexes, existing feedback, and focused store tests. The earlier CAS, linked-session projection, indexing, notes-patch, and migration-fixture findings are resolved.

I left three inline P2 comments covering exact-shape validation, monotonic mutation timestamps, and cursor/filter binding. None is a P0/P1, and I do not think this needs a broader redesign or PR split.

Two non-blocking test-truth follow-ups:

• The concurrent-mutation test uses one store, so it proves process-local serialization but would still pass without the cross-process BEGIN IMMEDIATE fix. I would keep it and name it accordingly; a worker/barrier test can cover cross-process CAS if that guarantee needs executable protection.
• The query-plan test is valuable, but it explains a handwritten copy of the list SQL rather than the SQL produced by list(). Sharing an internal query builder would keep the regression test tied to production without adding a public API.

I would keep the remaining contract, persistence, migration, archive, backup, and index tests; they cover distinct lifecycle seams rather than duplicating one another. Overall, the Work Board / SessionTodo authority split is sound, and the current Phase 0 scope is appropriately reduced.

中文对照

感谢持续处理前几轮 review。我重新检查了当前 head，包括 Core 契约、SQLite 生命周期、migration、索引、已有反馈和聚焦的 store 测试。之前的 CAS、linked-session projection、索引、notes patch 和 migration fixture 问题都已经解决。

我留下了三条 inline P2，分别涉及：

• 对 Work Board item 和 mutation input 进行 exact-shape 校验，避免未知字段被静默接受或在下一次写入时丢失；
• 在持久化事务中保持 mutation timestamp 单调，避免系统时钟回拨破坏 keyset pagination；
• 将 opaque cursor 与规范化后的 scope / includeArchived filters 绑定，避免跨结果集复用时静默漏项。

它们都不是 P0/P1，也不需要扩大成整体重构或拆分 PR。

另外有两项非阻塞的测试真实性建议：

• 当前并发 mutation 测试使用同一个 store，因此证明的是进程内串行化；即使没有跨进程 BEGIN IMMEDIATE 修复，它仍会通过。建议保留并让测试名称准确表达该范围；如需可执行地保护跨进程 CAS，再补 worker/barrier 测试。
• Query-plan 测试有价值，但它解释的是手写的 list SQL 副本，而不是 list() 实际生成的 SQL。共享内部 query builder 可以防止测试与生产查询逐渐漂移，同时不需要扩大公共 API。

其余 contract、persistence、migration、archive、backup 和 index 测试覆盖不同生命周期，不建议删除。总体而言，Work Board 与 SessionTodo 的权威边界正确，Phase 0 的当前范围也已经合理收缩。

AI-assisted review disclosure: Codex performed the primary lifecycle review and executable reproductions; three independent Codex reviewers covered contract scope, SQLite behavior, and test truthfulness; Claude performed a focused adversarial adjudication. The final findings were verified against the current PR head.

packages/storage/src/work-board-store.ts:358

• workBoardFilterFingerprint embeds the full projectId (max 160 chars) into filterFingerprint, but decodeCursor rejects fingerprints longer than 128 and the contract bounds cursor strings to 256 chars. For long project IDs this will produce an overlong cursor (and/or an undecodable cursor), causing pagination to fail after the first page with "cursor does not match the list filters".

@somewan820 Verified.

• The cursor test now confirms that the second page has a different item ID.
• WorkBoardStore.list() and the query-plan test both use buildWorkBoardListStatement.
• The migration guard returns before migrateSqliteWorkflowDatabase on a current target schema. The DROP INDEX does not run on normal opens.

The remaining implementation findings are addressed. The index-rebuild finding remains withdrawn.

Learning: In `packages/storage/src/sqlite-workflow-schema.ts`, `migrateSqliteWorkflowDatabase` intentionally drops and recreates `workflow_work_board_items_scope_order`. An intermediate Phase 0 development build created the same index name with `item_id ASC` while registering schema version 9. `inspectAndMigrateOperationalState` only runs this migration when the schema registry or target schema does not match, so the drop executes only during migration. SQLite `CREATE INDEX IF NOT EXISTS` cannot replace the old same-name index definition.

• This test name says “cross-process”, but it uses Worker from node:worker_threads, which is cross-thread (same process) rather than cross-process. Either rename the test to match what it actually exercises, or switch to a child-process based worker if you truly need a cross-process regression.

• If you keep using worker threads here, process.pid is the same across all workers, which makes the “winner” update harder to distinguish when debugging. Importing and using threadId gives each worker a unique identifier within the process.

Follow-up: I reviewed the current head (688051767). The requested Phase 0 scope changes, active-row partial indexes with archive-heavy coverage, and Astro-Han’s subsequent P2 findings are resolved. The remaining test-truth caveat is non-blocking. This PR is ready to merge.

[liugddx]

Approved. The current head satisfies the approved Phase 0 contract and resolves the outstanding review findings.

[Astro-Han]

Thanks for carrying the earlier review rounds through to a coherent Phase 0 boundary. I rechecked the current head after the maintainer approval, including the Core contract, SQLite lifecycle, migration/index paths, prior feedback, and focused tests.

The previous CAS transaction, linked-session deferral, active-row indexes, monotonic mutation timestamps, filter-bound cursors, and cursor-size fixes all hold. I found two remaining runtime-boundary gaps and left them inline:

• create/stored notes still accepts null even though that clear signal belongs only to update patches;
• unknown mutation-option keys can silently disable expectedRevision CAS.

Both are narrow exact-validation fixes at the existing owners. They do not call for reopening the product scope, redesigning the store, or splitting this PR.

Focused verification on 688051767:

• @maka/core build: passed
• @maka/storage build: passed
• Work Board storage test file: 17/17 passed
• visible GitHub checks: green

Once the two inline issues are addressed, this should only need a quick final pass.

中文版

感谢把前几轮 review 收敛成连贯的 Phase 0 边界。我在 maintainer Approve 之后重新检查了同一个当前 head，包括 Core 契约、SQLite 生命周期、migration/index、已有反馈和聚焦测试。

此前的 CAS 事务、linked-session 推迟、active partial indexes、mutation 时间戳单调性、游标与过滤条件绑定，以及游标长度问题都已经正确解决。

目前还剩两个运行时边界缺口，已分别留下 inline comment：create/持久化记录仍会接受 notes: null；mutation options 的未知字段可能静默关闭 expectedRevision CAS。两者都只需要在现有 owner 上补齐精确校验，不需要重新讨论产品范围、重构 store 或拆分 PR。

当前 head 的 Core/Storage 构建通过，Work Board storage 聚焦测试 17/17 通过，GitHub 可见检查全绿。处理完两条 inline 后，快速复核即可。

Astro-Han — both P2 inline comments are fixed in cbf2dc64a (details in the threads):

• notes: null is now rejected in create input and stored records; null remains the explicit clear signal only in update patches.
• Mutation options are validated as an exact-shape object, so unknown keys like expectedRevison or extra fields throw invalid_input instead of silently disabling expectedRevision CAS.

Verification: core + storage focused tests pass (33 tests), both packages build/typecheck, Biome clean. liugddx already approved the prior head; the new commit only contains these two narrow validation fixes.

Could you take the quick final pass? If everything looks good, this PR is ready to merge. @liugddx — happy to merge once Astro-Han confirms.

简体中文

Astro-Han —— 两条 P2 代码评论已在 cbf2dc64a 修复（详见对应线程）：

• create input 和已存记录现在拒绝 notes: null；null 只保留为 update patch 的显式清除信号。
• mutation options 改为精确形状校验，expectedRevison 这类拼写错误或多余字段会直接 invalid_input，不会再静默关闭 expectedRevision CAS。

验证：core + storage focused tests 全部通过（33 个），两个包 build/typecheck 通过，Biome 干净。liugddx 已对前一版 head 表示 approve；本次新 commit 只包含这两处窄校验修复。

能否做最后一次快速复核？如果没问题，这个 PR 就可以合并了。@liugddx —— Astro-Han 确认后就可以 merge。

[Astro-Han]

Thanks for the quick follow-up. I rechecked the current head (cbf2dc64a) and both remaining P2 findings are resolved:

• create input and durable records now reject notes: null, while update patches retain null as the explicit clear signal;
• mutation options now fail closed on unknown keys, so a misspelled or extra field cannot silently disable expectedRevision CAS.

The regression tests exercise the real contract/store boundaries and verify that rejected mutation options leave the stored revision and state unchanged. I found no remaining P0–P3 issues.

The Phase 0 authority boundary remains intact: Core owns the item contract, Storage owns durable mutation and CAS, and no Runtime execution state or parallel authority has been introduced. The current solution is the smallest complete implementation of the approved scope; it does not need further restructuring or a PR split.

Verification on cbf2dc64a:

• @maka/core build and focused Work Board tests: 15/15 passed
• @maka/storage build and focused Work Board tests: 18/18 passed
• Biome formatting check on the four changed files: passed
• git diff --check: passed
• visible GitHub checks: green
• merge state: clean

Approved from my side.

感谢快速处理。我重新检查了当前 head（cbf2dc64a），最后两条 P2 都已解决：

• create input 和持久化记录现在拒绝 notes: null，同时 update patch 仍保留 null 作为显式清除信号；
• mutation options 现在会拒绝未知字段，因此拼错或多余字段不会再静默关闭 expectedRevision CAS。

回归测试覆盖了真实的契约和 store 边界，并验证 mutation options 被拒绝后，持久化 revision 和 state 都不会变化。目前没有剩余 P0–P3。

Phase 0 的权威边界保持清晰：Core 负责 item contract，Storage 负责持久化 mutation 与 CAS，没有引入 Runtime 执行状态副本或平行 authority。当前方案已经是已批准范围内的最小完整实现，不需要继续重构或拆分 PR。

当前 head 的 Core/Storage build 通过，聚焦测试分别为 15/15 与 18/18，Biome、git diff --check 和 GitHub checks 均通过，merge state 为 clean。

我这边 approve。

Work Board Phase 0

This PR implements the maintainer-approved Phase 0 Work Board contract (see the 7-point review and accepted revision in #2560).

Key points:

• durable Work Board items with no total item cap
• bounded pagination (default 50, max 100)
• explicit todo/in_progress/done lifecycle
• strict provenance union (manual / main_conversation / side_conversation)
• SQLite scope/project invariant
• semantic patch mutation semantics
• monotonic revision + optional expectedRevision CAS
• serialized transactional writes (BEGIN IMMEDIATE)
• archive-before-delete semantics
• active-row partial indexes so default list queries stay bounded under archive-heavy data
• schema 8 -> 9 additive migration
• fail-closed corruption detection

Maintainer-confirmed deferrals (liugddx, #2560):

• linkedSessions moves to Phase 3; Phase 0 rejects the field in create input and stored records
• linked-session projection is deferred to Phase 3; it will be implemented beside the canonical Runtime Host / Desktop continuity adapter against SessionContinuitySnapshot / TurnSnapshot

Intentionally deferred:

• Task Ledger integration
• Runtime Host integration
• model-visible Work Board tools
• recovery/graph state
• resultRefs
• automatic completion

Verification

• core + storage focused tests pass (30 tests)
• @maka/core and @maka/storage build/typecheck
• Biome clean
• migration: v0.1.6 fixture + exact v8 DDL -> real 8->9 path; old schema objects retained; partial indexes present
• archive-heavy list queries covered by EXPLAIN QUERY PLAN regression test against the production query builder
• cross-process CAS covered by a worker-thread test (one winner, one operation_conflict)

Checklist

• Phase 0 contract matches the maintainer-approved scope and deferrals
• Migration is additive (8 -> 9) with no user-data DROP
• Tests updated and passing
• Docs and PR description current

Refs #2560

[Astro-Han]

Thanks for defining the Work Board authority boundary before adding UI or Runtime integration.

Before getting into the implementation details, I think the product scope should be reconciled with the more recent decision in #2290. That discussion deliberately reduced the Session Task Ledger to a narrow Session-local Todo snapshot: no stable item identity, per-item CRUD, hierarchy, evidence, pagination, or workflow UI.

I understand that #2560 describes a different owner: Work Board items are user-owned, cross-Session deferred intentions, while SessionTodo is a model-authored progress snapshot. I am not suggesting that Work Board should reuse SessionTodo or the Task Ledger.

The remaining question is whether this distinct product surface needs a full Work Board domain yet. This PR introduces another durable task-like entity with stable IDs, per-item mutations, scopes, provenance variants, a state machine, archive/delete behavior, pagination, revisions, and future Session links—before there is a UI or production caller. That appears to reintroduce much of the product and maintenance complexity that #2290 has just removed from the existing task system.

Could we first establish why a minimal user-owned Todo list is insufficient for the actual problem of “remember this for later without interrupting the current Session”? A small vertical slice—capture, list, complete, and delete, with optional project/source context—would validate the user need without fixing the larger Board contract in schema v1. Session linking and execution projection could then be added when “start as task” has a real consumer.

If the broader Work Board scope remains intentional after that reconciliation, I found three implementation issues that seem worth resolving before the Phase 0 schema is published:

1. The revision check is outside the SQLite write transaction. Two processes can both read revision 1, both pass expectedRevision: 1, both write revision 2, and the later write silently overwrites the earlier semantic patch. Please make the read/check/write sequence one BEGIN IMMEDIATE transaction, or use conditional UPDATE/DELETE ... WHERE revision = ? statements and treat zero affected rows as a conflict.

2. The linked-session projector validates a new DTO rather than the canonical SessionContinuitySnapshot. It also uses Core TurnStatus, which rejects valid continuity states such as waiting_for_user and cancelled. Since there is no production consumer yet, the simplest option may be to defer this projector until it can live beside the real Runtime Host/Desktop continuity adapter instead of introducing a parallel contract now.

3. The new index does not satisfy the list ordering. The default unscoped query performs a full-table scan and temporary sort, while scoped queries still require a temporary sort for the final key because item_id has the opposite direction. Since the contract intentionally has no total item cap, pagination currently bounds returned rows but not query work. Please align the indexes with the actual scoped/unscoped query shapes before schema v9 is released.

The focused tests and current CI are green. I would also replace the fresh-database “migration” test with a real schema-8 upgrade fixture, but I see that as a verification improvement rather than a separate production finding.

简体中文

感谢你在增加 UI 或 Runtime 集成前，先明确 Work Board 的权威边界。

在讨论具体实现前，我认为这里的产品范围需要先与 #2290 中较新的决定重新对齐。该讨论刚刚把 Session Task Ledger 明确收缩为一个很窄的 Session-local Todo 快照：没有稳定的事项身份、逐项 CRUD、层级、证据、分页或 workflow UI。

我理解 #2560 定义的是另一个 owner：Work Board 是用户拥有的、跨 Session 的暂缓事项；SessionTodo 则是模型写入的进度快照。我并不是建议 Work Board 复用 SessionTodo 或 Task Ledger。

真正需要确认的是：这个独立的产品界面现在是否已经需要一套完整的 Work Board 领域模型。本 PR 在还没有 UI 和生产调用方时，就引入了另一个持久化的 task-like 实体，包括稳定 ID、逐项 mutation、scope、多种 provenance、状态机、归档/删除、分页、revision，以及未来的 Session 关联。这似乎重新引入了 #2290 刚从现有任务系统中删除的大量产品与维护复杂度。

我们是否应该先说明：对于“记住这个后续事项，但不要打断当前 Session”这一真实问题，为什么一个最小的、用户拥有的 Todo 列表还不够？先交付一条较小的纵向链路——保存、列出、完成和删除，并按需携带项目或来源上下文——就可以验证用户需求，而不必现在把更大的 Board contract 固化进 schema v1。等“启动为任务”出现真实消费者时，再增加 Session 关联和执行状态投影也不迟。

如果重新对齐后，完整的 Work Board 范围仍然是有意保留的，我还发现三个建议在发布 Phase 0 schema 前解决的实现问题：

1. revision 检查发生在 SQLite 写事务之外。两个进程可以同时读到 revision 1，都通过 expectedRevision: 1，然后分别写入 revision 2；后写入的 semantic patch 会静默覆盖前一次修改。建议把读取、检查和写入放进同一个 BEGIN IMMEDIATE 事务，或者使用带 WHERE revision = ? 条件的 UPDATE/DELETE，并将影响行数为零视为冲突。

2. linked-session projector 校验的是一套新定义的 DTO，而不是权威的 SessionContinuitySnapshot。它还使用了 Core TurnStatus，因此会拒绝 waiting_for_user、cancelled 等合法的 continuity 状态。当前还没有生产调用方，最简单的方案可能是先推迟这个 projector，等真实的 Runtime Host/Desktop continuity adapter 出现时再贴近实际 owner 实现，避免现在引入一份平行契约。

3. 新增索引不能满足 list 的实际排序。默认的无 scope 查询会全表扫描并临时排序；scoped 查询也会因为 item_id 的索引方向与查询相反，对最后一个排序键进行临时排序。由于契约明确不设置事项总量上限，目前分页只限制了返回行数，并没有限制每页查询的工作量。建议在 schema v9 发布前，让索引与 scoped/unscoped 查询的真实形态一致。

Focused tests 和当前 CI 均已通过。我还建议把“从空数据库创建 v9”的 migration 测试替换成真实的 schema 8 升级 fixture，不过这属于验证改进，不是独立的生产 finding。

AI-assisted review disclosure: Codex and Claude Opus were used to inspect the change and challenge the findings. I reproduced and adjudicated the issues above against the current source and own this review.

[somewan820]

Thanks for the review. I have verified all three implementation findings and fixed them in 476eb218b:

1. Revision CAS — update / archive / unarchive / remove now run the full read → revision check → write sequence inside one BEGIN IMMEDIATE transaction. The in-process write queue is retained for process-local serialization; the transaction closes the cross-process race. I confirmed the shared transaction helper flattens the nested #writeItem call, so there is no premature commit.

2. Linked-session projection — work-board-session-projection.ts (module, test, and package export) is removed. It was a parallel DTO validated with Core TurnStatus, which cannot represent waiting_for_user / cancelled from the canonical continuity contract. With no production consumer in Phase 0, I agree the projector should wait until Phase 3 and live beside the real Runtime Host / Desktop continuity adapter.

3. Indexes — schema v9 now ships (scope_kind, project_id, updated_at DESC, item_id DESC) and (updated_at DESC, item_id DESC). I verified against populated data with EXPLAIN QUERY PLAN: the default unscoped query, scoped queries (project and inbox), and both cursor forms use the indexes and no longer perform a full-table scan or temporary sort.

The migration test now builds a real schema-8 database from the released v0.1.6 operational-state fixture plus the exact v8 workflow DDL, then runs the actual 8→9 migration path and checks that the board table exists and the old schema objects remain.

On the product-scope question, I would like to separate PR fidelity from contract re-scoping:

• Fidelity to product(desktop): capture deferred work in a project-aware Work Board #2560: every semantic in this PR maps to the maintainer-approved Phase 0 contract from liugddx's review (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)) and the accepted revision (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)). Most of the surface you listed is load-bearing for that contract: pagination and archive/delete replaced the total-item cap the maintainer removed; revision/CAS was explicitly requested for concurrent renderer writes; provenance variants are required for side-chat capture to survive fork deletion; stable identity is the reference point Phase 3 "start as task" will need.

• RFC: Radically slim the Session Task Ledger #2290's Option 2 governs SessionTodo, not Work Board: the explicit-absent list in RFC: Radically slim the Session Task Ledger #2290 applies to the model-authored, Session-local progress snapshot. Work Board is a different owner (user-owned, cross-Session). Your own acceptance comment in RFC: Radically slim the Session Task Ledger #2290 states that product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 may proceed independently and should not become a P3 integration dependency of RFC: Radically slim the Session Task Ledger #2290 (RFC: Radically slim the Session Task Ledger #2290 (comment)).

The one item I agree has no Phase 0 consumer today is linkedSessions: the field exists in the schema, but Phase 0 has no mutation path that writes it and no UI or runtime caller reads it; Phase 3 "start as task" is the intended consumer. Rather than removing a maintainer-approved field unilaterally, I would like a decision.

@liugddx, could you please confirm:

(a) Does Phase 0 remain the approved contract after #2290 Option 2, or should it be re-scoped to capture / list / complete / delete with optional project and source context?

(b) Should linkedSessions stay in schema v1, or move to Phase 3 via a future additive migration?

(c) Is the linked-session projection formally deferred (removed from the Phase 0 deliverables), or do you want it implemented in Phase 0 against the canonical SessionContinuitySnapshot / TurnSnapshot?

I will not push further commits until these are resolved.

简体中文

感谢 review。三个实现问题我都已核验并在 476eb218b 修复：

1. Revision CAS：update / archive / unarchive / remove 现在把“读取 → revision 校验 → 写入”完整放进同一个 BEGIN IMMEDIATE 事务。进程内 write queue 保留用于单进程串行化；事务关闭跨进程竞争窗口。我已确认共享事务助手会扁平化嵌套的 #writeItem 调用，不会提前提交。

2. Linked-session projection：work-board-session-projection.ts（模块、测试、package export）已删除。它是一套平行 DTO，用 Core TurnStatus 校验，无法表达 canonical continuity 中的 waiting_for_user / cancelled。Phase 0 没有生产消费者，我同意推迟到 Phase 3，并放到真实 Runtime Host / Desktop continuity adapter 旁边实现。

3. 索引：schema v9 现在包含 (scope_kind, project_id, updated_at DESC, item_id DESC) 和 (updated_at DESC, item_id DESC)。我用真实填充数据跑了 EXPLAIN QUERY PLAN：默认 unscoped 查询、scoped 查询（project 与 inbox）以及两种 cursor 形态都使用索引，不再全表扫描或临时排序。

Migration 测试现在用发布的 v0.1.6 operational-state fixture + 精确的 v8 workflow DDL 构造真实 schema-8 库，走完整 8→9 迁移路径，并断言新表存在、旧 schema 对象保留。

关于产品范围问题，我想把“PR 是否忠实”和“契约是否要重新收缩”分开：

• 对 product(desktop): capture deferred work in a project-aware Work Board #2560 的忠实度：本 PR 的每个 semantic 都能对应 liugddx 的 maintainer review（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294753604）和已接受的修订版（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294956443）。你点名的多数复杂度都是该契约的承重结构：分页和 archive/delete 替代了 maintainer 移除的总上限；revision/CAS 是并发 renderer 写入的明确要求；provenance variants 是 side-chat 捕获在 fork 删除后仍可追溯的验收条件；stable identity 是 Phase 3 “start as task” 需要的引用点。

• RFC: Radically slim the Session Task Ledger #2290 Option 2 约束的是 SessionTodo，不是 Work Board：RFC: Radically slim the Session Task Ledger #2290 的 explicitly-absent 列表针对 model-authored、Session-local 的进度快照。Work Board 是不同的 owner（user-owned、cross-Session）。你在 RFC: Radically slim the Session Task Ledger #2290 的接受评论里也明确写了 product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 可以独立推进，不应成为 RFC: Radically slim the Session Task Ledger #2290 的 P3 集成依赖（https://github.com/maka-agent/maka-agent/issues/2290#issuecomment-5298957426）。

我唯一同意“Phase 0 没有消费者”的是 linkedSessions：字段在 schema 里，但 Phase 0 没有任何 mutation 路径写入它，也没有 UI 或 runtime 调用方读取；Phase 3 “start as task” 才是消费者。与其单方面删除 maintainer 已批准的字段，我希望得到一个明确决定。

@liugddx 能否确认：

(a) #2290 Option 2 之后，Phase 0 是否仍然以已批准契约为准，还是收缩为 capture / list / complete / delete + 可选的 project/source context？

(b) linkedSessions 留在 schema v1，还是移到 Phase 3（未来 additive migration）？

(c) linked-session projection 是否正式推迟（从 Phase 0 交付物移除），还是要求在 Phase 0 基于 canonical SessionContinuitySnapshot / TurnSnapshot 实现？

在得到答复前我不会再 push 新 commit。

[liugddx]

Thanks for addressing Astro-Han's review carefully. I rechecked the updated implementation against the approved #2560 Phase 0 contract and the later #2290 Option 2 boundary.

My maintainer decisions are:

1. Phase 0 remains an independently approved Work Board contract.#2290 Option 2 narrows the model-authored, Session-local SessionTodo; it does not re-scope the user-owned, cross-Session Work Board into the same domain. The broader Phase 0 contract therefore does not need to be reduced to a generic Todo list solely because of #2290.
2. Move linkedSessions to Phase 3. It has no Phase 0 consumer, and it is already exposed as writable input through CreateWorkBoardItemInput and persisted by the create normalizer, so it is not merely a harmless reserved field. An additive migration when “start as task” has a real caller is the smaller and safer compatibility commitment.
3. The linked-session projection is formally deferred to Phase 3. Removing the parallel DTO was correct. Implement it beside the real Runtime Host/Desktop continuity adapter against canonical SessionContinuitySnapshot / TurnSnapshot facts when the consumer exists.

The CAS fix is correct: the read, revision check, and write now share one BEGIN IMMEDIATE transaction. The schema-8 upgrade fixture is also a meaningful improvement.

One implementation issue remains before merge: the index fix removes the temporary sort but does not bound filtering work for the default query. list() adds archived = 0, while neither ordering index contains archived. With an unbounded number of archived rows and few active rows, SQLite may still walk most of the ordering index to produce one active page. EXPLAIN QUERY PLAN reporting an index scan and no temporary B-tree does not disprove that scan cost.

Please add active-row partial indexes for both unscoped and scoped query shapes (or an equivalent design), and cover the archive-heavy case. After removing linkedSessions from the Phase 0 contract/store/tests and closing this remaining query-cost hole, the PR will match the approved authority boundary and be ready for another pass.

简体中文

感谢你认真处理 Astro-Han 的评审。我重新对照了已批准的 #2560 Phase 0 契约和后续 #2290 Option 2 的权威边界。

我的 maintainer 决策如下：

1. Phase 0 继续作为独立批准的 Work Board 契约推进。#2290 Option 2 收缩的是模型写入、Session-local 的 SessionTodo，并没有把用户拥有、跨 Session 的 Work Board 收缩进同一个领域。因此，不能仅因为 #2290 就把完整 Phase 0 再缩成普通 Todo 列表。
2. linkedSessions 移到 Phase 3。 Phase 0 没有消费者，而且它已经通过 CreateWorkBoardItemInput 暴露为可写输入，并由 create normalizer 持久化，所以它并不是一个无害的预留字段。等“启动为任务”出现真实调用方时，通过增量迁移增加，是更小、更安全的兼容性承诺。
3. linked-session projection 正式推迟到 Phase 3。 删除平行 DTO 是正确的。等真实消费者出现时，再放到 Runtime Host/Desktop continuity adapter 旁，基于规范的 SessionContinuitySnapshot / TurnSnapshot 事实实现。

CAS 修复成立：读取、revision 校验和写入现在位于同一个 BEGIN IMMEDIATE 事务中。真实 schema-8 升级 fixture 也是有意义的改进。

合并前还剩一个实现问题：索引修复消除了临时排序，但没有限制默认查询的过滤工作量。list() 会添加 archived = 0，但两个排序索引都不包含 archived。当归档记录无上限、活动记录很少时，SQLite 为返回一页活动事项仍可能遍历排序索引中的大多数记录。EXPLAIN QUERY PLAN 显示使用索引且没有临时 B-tree，并不能证明扫描成本受限。

请为 scoped 和 unscoped 的活动项查询增加 partial indexes（或等价设计），并覆盖“绝大多数记录已归档”的情况。删除 Phase 0 contract/store/tests 中的 linkedSessions，并补齐这个查询成本缺口后，本 PR 就能符合已批准的权威边界，可以进入下一轮评审。

📝 Walkthrough

Summary

• Problem solved

  • Adds the Phase 0 Work Board contract and durable SQLite storage.
  • Supports validated item creation, updates, listing, archiving, restoring, and removal.
  • Adds bounded cursor pagination, provenance checks, lifecycle invariants, semantic patches, and revision-based optimistic concurrency.
  • Detects corrupt records and rejects invalid scope, project, revision, timestamp, and archive data.

• Source of truth

  • Extends the existing packages/core contract and packages/storage SQLite workflow schema.
  • Does not create a parallel linked-session path. linkedSessions and linked-session projection remain deferred to Phase 3.

• Implementation scope

  • Provides the smallest coherent Phase 0 solution.
  • BEGIN IMMEDIATE transactions and the process-local write queue are necessary for serialized mutations and revision checks.
  • Schema migration 8→9 and active, scoped, cursor, and archive indexes support compatibility and query performance.

• Simplification

  • The removed linked-session projection does not reduce Phase 0 behavior or regression coverage.
  • Task Ledger, Runtime Host, model-visible tools, recovery state, result references, and automatic completion remain outside this change.
  • No further deletion or simplification is apparent without weakening behavior or regression coverage.

• Risks and validation

  • Main risks include migration compatibility, concurrent revision conflicts, pagination correctness, SQLite constraint enforcement, timestamp ordering, cursor scope binding, and corrupt-record detection.
  • Tests cover contract behavior, storage operations, worker-thread and cross-process CAS races, pagination, query plans, corruption, constraints, migration, and backup/restore.
  • Reported validation includes passing focused tests, successful builds and typechecks for both packages, and clean Biome checks.
  • Required-check status remains unverified because no direct repository check result is available.

Review-relevant risks

• The PR changes public packages/core and packages/storage exports and adds a durable SQLite schema migration. These are public-contract and release-affecting changes. Material changes in these areas require independent human review under repository policy.
• The PR changes persisted data behavior, including archive-before-delete enforcement, scope/project constraints, migrations, and corruption handling. These changes can affect user data and operational recovery. Material changes in these areas require independent human review under repository policy.
• No security, licensing, or governance effect was identified in the current diff.
• The person performing the merge reviews the final diff. A maintainer makes the final determination.

Thanks for the maintainer decisions. I've applied them in 833481e64:

• linkedSessions is removed from the Phase 0 contract, create input, store, and tests. The Phase 0 normalizer and decoder now reject the field (fail-closed), and the contract doc records it as a Phase 3 addition.
• The linked-session projection stays deferred to Phase 3, documented in the contract and the PR description.
• Active-row partial indexes were added for both default query shapes: workflow_work_board_items_active_order and workflow_work_board_items_active_scope_order (both WHERE archived = 0). The existing full ordering indexes remain for includeArchived queries.
• Archive-heavy coverage: the new storage test creates 120 archived + 6 active items, asserts list behavior, and verifies via EXPLAIN QUERY PLAN that default unscoped and scoped queries use the partial indexes without a temporary sort. The migration test also asserts both partial indexes exist after the 8→9 upgrade.

Verification: core + storage focused tests pass (26 tests), both packages build/typecheck, Biome is clean.

The PR is now ready for review. Let me know if you'd like any further adjustments.

感谢 maintainer 的决定。我已在 833481e64 全部落地：

• linkedSessions 已从 Phase 0 契约、create input、store 和测试中移除；Phase 0 的 normalizer 和 decoder 现在会拒绝该字段（fail-closed），契约文档记录为 Phase 3 加入。
• linked-session projection 保持推迟到 Phase 3，已写入契约文档和 PR description。
• 为两种默认查询形态新增 active-row partial index：workflow_work_board_items_active_order 和 workflow_work_board_items_active_scope_order（均为 WHERE archived = 0）；原有全量排序索引保留给 includeArchived 查询。
• Archive-heavy 覆盖：新增 storage 测试构造 120 条 archived + 6 条 active，断言 list 行为，并用 EXPLAIN QUERY PLAN 验证默认 unscoped/scoped 查询使用 partial index、无临时排序；migration 测试同时断言 8→9 升级后两个 partial index 存在。

验证：core + storage focused tests 全部通过（26 个），两个包 build/typecheck 通过，Biome 干净。

A corrupt row can never be deleted.

remove calls #requireItem, which decodes the row and throws corrupt_record when record_json is unparseable or disagrees with the indexed columns. The fail-closed read is correct, but it also blocks the only removal path. A user who hits a corrupt item cannot repair the board.

Add a repair path. One option is to allow deletion when expectedRevision matches the indexed revision column, without decoding record_json.

The cursor does not bind to the query filters.

encodeCursor stores only updatedAt and itemId. A cursor returned by an inbox-scoped page decodes successfully and applies without complaint to a project-scoped query or to an includeArchived: true query. The caller then receives a page that looks coherent but silently starts from an unrelated position in a different result set.

Include a filter fingerprint in the cursor payload, and reject a cursor whose fingerprint does not match the current query.

Bind the query-plan assertions to the store's own SQL.

The test hand-writes the list SQL. The store builds its list SQL internally. The assertions therefore prove only that the indexes serve this copy of the query. If the store query later changes its filter shape, ORDER BY, or limit, this test stays green while the production path falls back to a scan or a temp sort.

Export the query text (or a small explainListPlan helper) from work-board-store.ts and assert the plan for that exact string.

packages/core/src/work-board.ts:494

• Unarchive can currently decrease updatedAt if now is earlier than the stored updatedAt (e.g. wall clock skew). Because list ordering/pagination uses updatedAt, clamp this to keep timestamps monotonic (see e.g. sqlite-long-term-memory-store.ts:953).

 item: {
...activeFields,
archived: false,
updatedAt: now,
revision: item.revision + 1,
},

packages/core/src/work-board.ts:476

• Archive timestamps should be monotonic even if the wall clock moves backwards; otherwise an archive mutation can decrease updatedAt and break ordering/pagination. Consider clamping both archivedAt and updatedAt to at least the current item.updatedAt (consistent with other storage authorities).

 ...item,
archived: true,
archivedAt: now,
updatedAt: now,
revision: item.revision + 1,

packages/core/src/work-board.ts:460

• updatedAt can move backwards if the caller clock moves backwards (or a test/consumer passes an older now). Since list pagination/orders are keyed on updatedAt, a decreasing timestamp can cause incorrect ordering and cursor paging anomalies. Other stores clamp mutation timestamps to be monotonic (e.g. packages/storage/src/sqlite-long-term-memory-store.ts:953, packages/storage/src/managed-secret-store.ts:430-432).

This issue also appears in the following locations of the same file:

• line 472
• line 489

 ...(notes === undefined ? {} : { notes }),
scope,
state,
updatedAt: now,
revision: item.revision + 1,

Thanks for working through the earlier review rounds. I rechecked the current head, including the Core contract, SQLite lifecycle, migration, indexes, existing feedback, and focused store tests. The earlier CAS, linked-session projection, indexing, notes-patch, and migration-fixture findings are resolved.

I left three inline P2 comments covering exact-shape validation, monotonic mutation timestamps, and cursor/filter binding. None is a P0/P1, and I do not think this needs a broader redesign or PR split.

Two non-blocking test-truth follow-ups:

• The concurrent-mutation test uses one store, so it proves process-local serialization but would still pass without the cross-process BEGIN IMMEDIATE fix. I would keep it and name it accordingly; a worker/barrier test can cover cross-process CAS if that guarantee needs executable protection.
• The query-plan test is valuable, but it explains a handwritten copy of the list SQL rather than the SQL produced by list(). Sharing an internal query builder would keep the regression test tied to production without adding a public API.

I would keep the remaining contract, persistence, migration, archive, backup, and index tests; they cover distinct lifecycle seams rather than duplicating one another. Overall, the Work Board / SessionTodo authority split is sound, and the current Phase 0 scope is appropriately reduced.

中文对照

感谢持续处理前几轮 review。我重新检查了当前 head，包括 Core 契约、SQLite 生命周期、migration、索引、已有反馈和聚焦的 store 测试。之前的 CAS、linked-session projection、索引、notes patch 和 migration fixture 问题都已经解决。

我留下了三条 inline P2，分别涉及：

• 对 Work Board item 和 mutation input 进行 exact-shape 校验，避免未知字段被静默接受或在下一次写入时丢失；
• 在持久化事务中保持 mutation timestamp 单调，避免系统时钟回拨破坏 keyset pagination；
• 将 opaque cursor 与规范化后的 scope / includeArchived filters 绑定，避免跨结果集复用时静默漏项。

它们都不是 P0/P1，也不需要扩大成整体重构或拆分 PR。

另外有两项非阻塞的测试真实性建议：

• 当前并发 mutation 测试使用同一个 store，因此证明的是进程内串行化；即使没有跨进程 BEGIN IMMEDIATE 修复，它仍会通过。建议保留并让测试名称准确表达该范围；如需可执行地保护跨进程 CAS，再补 worker/barrier 测试。
• Query-plan 测试有价值，但它解释的是手写的 list SQL 副本，而不是 list() 实际生成的 SQL。共享内部 query builder 可以防止测试与生产查询逐渐漂移，同时不需要扩大公共 API。

其余 contract、persistence、migration、archive、backup 和 index 测试覆盖不同生命周期，不建议删除。总体而言，Work Board 与 SessionTodo 的权威边界正确，Phase 0 的当前范围也已经合理收缩。

AI-assisted review disclosure: Codex performed the primary lifecycle review and executable reproductions; three independent Codex reviewers covered contract scope, SQLite behavior, and test truthfulness; Claude performed a focused adversarial adjudication. The final findings were verified against the current PR head.

packages/storage/src/work-board-store.ts:358

• workBoardFilterFingerprint embeds the full projectId (max 160 chars) into filterFingerprint, but decodeCursor rejects fingerprints longer than 128 and the contract bounds cursor strings to 256 chars. For long project IDs this will produce an overlong cursor (and/or an undecodable cursor), causing pagination to fail after the first page with "cursor does not match the list filters".

@somewan820 Verified.

• The cursor test now confirms that the second page has a different item ID.
• WorkBoardStore.list() and the query-plan test both use buildWorkBoardListStatement.
• The migration guard returns before migrateSqliteWorkflowDatabase on a current target schema. The DROP INDEX does not run on normal opens.

The remaining implementation findings are addressed. The index-rebuild finding remains withdrawn.

Learning: In `packages/storage/src/sqlite-workflow-schema.ts`, `migrateSqliteWorkflowDatabase` intentionally drops and recreates `workflow_work_board_items_scope_order`. An intermediate Phase 0 development build created the same index name with `item_id ASC` while registering schema version 9. `inspectAndMigrateOperationalState` only runs this migration when the schema registry or target schema does not match, so the drop executes only during migration. SQLite `CREATE INDEX IF NOT EXISTS` cannot replace the old same-name index definition.

• This test name says “cross-process”, but it uses Worker from node:worker_threads, which is cross-thread (same process) rather than cross-process. Either rename the test to match what it actually exercises, or switch to a child-process based worker if you truly need a cross-process regression.

• If you keep using worker threads here, process.pid is the same across all workers, which makes the “winner” update harder to distinguish when debugging. Importing and using threadId gives each worker a unique identifier within the process.

Follow-up: I reviewed the current head (688051767). The requested Phase 0 scope changes, active-row partial indexes with archive-heavy coverage, and Astro-Han’s subsequent P2 findings are resolved. The remaining test-truth caveat is non-blocking. This PR is ready to merge.

[liugddx]

Approved. The current head satisfies the approved Phase 0 contract and resolves the outstanding review findings.

[Astro-Han]

Thanks for carrying the earlier review rounds through to a coherent Phase 0 boundary. I rechecked the current head after the maintainer approval, including the Core contract, SQLite lifecycle, migration/index paths, prior feedback, and focused tests.

The previous CAS transaction, linked-session deferral, active-row indexes, monotonic mutation timestamps, filter-bound cursors, and cursor-size fixes all hold. I found two remaining runtime-boundary gaps and left them inline:

• create/stored notes still accepts null even though that clear signal belongs only to update patches;
• unknown mutation-option keys can silently disable expectedRevision CAS.

Both are narrow exact-validation fixes at the existing owners. They do not call for reopening the product scope, redesigning the store, or splitting this PR.

Focused verification on 688051767:

• @maka/core build: passed
• @maka/storage build: passed
• Work Board storage test file: 17/17 passed
• visible GitHub checks: green

Once the two inline issues are addressed, this should only need a quick final pass.

中文版

感谢把前几轮 review 收敛成连贯的 Phase 0 边界。我在 maintainer Approve 之后重新检查了同一个当前 head，包括 Core 契约、SQLite 生命周期、migration/index、已有反馈和聚焦测试。

此前的 CAS 事务、linked-session 推迟、active partial indexes、mutation 时间戳单调性、游标与过滤条件绑定，以及游标长度问题都已经正确解决。

目前还剩两个运行时边界缺口，已分别留下 inline comment：create/持久化记录仍会接受 notes: null；mutation options 的未知字段可能静默关闭 expectedRevision CAS。两者都只需要在现有 owner 上补齐精确校验，不需要重新讨论产品范围、重构 store 或拆分 PR。

当前 head 的 Core/Storage 构建通过，Work Board storage 聚焦测试 17/17 通过，GitHub 可见检查全绿。处理完两条 inline 后，快速复核即可。

AI-assisted review: Codex performed the primary review and executable reproductions; four independent Codex reviewers adversarially checked the Core contract, SQLite lifecycle, migration/test evidence, and overall architecture.

Astro-Han — both P2 inline comments are fixed in cbf2dc64a (details in the threads):

• notes: null is now rejected in create input and stored records; null remains the explicit clear signal only in update patches.
• Mutation options are validated as an exact-shape object, so unknown keys like expectedRevison or extra fields throw invalid_input instead of silently disabling expectedRevision CAS.

Verification: core + storage focused tests pass (33 tests), both packages build/typecheck, Biome clean. liugddx already approved the prior head; the new commit only contains these two narrow validation fixes.

Could you take the quick final pass? If everything looks good, this PR is ready to merge. @liugddx — happy to merge once Astro-Han confirms.

简体中文

Astro-Han —— 两条 P2 代码评论已在 cbf2dc64a 修复（详见对应线程）：

• create input 和已存记录现在拒绝 notes: null；null 只保留为 update patch 的显式清除信号。
• mutation options 改为精确形状校验，expectedRevison 这类拼写错误或多余字段会直接 invalid_input，不会再静默关闭 expectedRevision CAS。

验证：core + storage focused tests 全部通过（33 个），两个包 build/typecheck 通过，Biome 干净。liugddx 已对前一版 head 表示 approve；本次新 commit 只包含这两处窄校验修复。

能否做最后一次快速复核？如果没问题，这个 PR 就可以合并了。@liugddx —— Astro-Han 确认后就可以 merge。

[Astro-Han]

Thanks for the quick follow-up. I rechecked the current head (cbf2dc64a) and both remaining P2 findings are resolved:

• create input and durable records now reject notes: null, while update patches retain null as the explicit clear signal;
• mutation options now fail closed on unknown keys, so a misspelled or extra field cannot silently disable expectedRevision CAS.

The regression tests exercise the real contract/store boundaries and verify that rejected mutation options leave the stored revision and state unchanged. I found no remaining P0–P3 issues.

The Phase 0 authority boundary remains intact: Core owns the item contract, Storage owns durable mutation and CAS, and no Runtime execution state or parallel authority has been introduced. The current solution is the smallest complete implementation of the approved scope; it does not need further restructuring or a PR split.

Verification on cbf2dc64a:

• @maka/core build and focused Work Board tests: 15/15 passed
• @maka/storage build and focused Work Board tests: 18/18 passed
• Biome formatting check on the four changed files: passed
• git diff --check: passed
• visible GitHub checks: green
• merge state: clean

Approved from my side.

感谢快速处理。我重新检查了当前 head（cbf2dc64a），最后两条 P2 都已解决：

• create input 和持久化记录现在拒绝 notes: null，同时 update patch 仍保留 null 作为显式清除信号；
• mutation options 现在会拒绝未知字段，因此拼错或多余字段不会再静默关闭 expectedRevision CAS。

回归测试覆盖了真实的契约和 store 边界，并验证 mutation options 被拒绝后，持久化 revision 和 state 都不会变化。目前没有剩余 P0–P3。

Phase 0 的权威边界保持清晰：Core 负责 item contract，Storage 负责持久化 mutation 与 CAS，没有引入 Runtime 执行状态副本或平行 authority。当前方案已经是已批准范围内的最小完整实现，不需要继续重构或拆分 PR。

当前 head 的 Core/Storage build 通过，聚焦测试分别为 15/15 与 18/18，Biome、git diff --check 和 GitHub checks 均通过，merge state 为 clean。

我这边 approve。

Work Board Phase 0

This PR implements the maintainer-approved Phase 0 Work Board contract (see the 7-point review and accepted revision in #2560).

Key points:

• durable Work Board items with no total item cap
• bounded pagination (default 50, max 100)
• explicit todo/in_progress/done lifecycle
• strict provenance union (manual / main_conversation / side_conversation)
• SQLite scope/project invariant
• semantic patch mutation semantics
• monotonic revision + optional expectedRevision CAS
• serialized transactional writes (BEGIN IMMEDIATE)
• archive-before-delete semantics
• active-row partial indexes so default list queries stay bounded under archive-heavy data
• schema 8 -> 9 additive migration
• fail-closed corruption detection

Maintainer-confirmed deferrals (liugddx, #2560):

• linkedSessions moves to Phase 3; Phase 0 rejects the field in create input and stored records
• linked-session projection is deferred to Phase 3; it will be implemented beside the canonical Runtime Host / Desktop continuity adapter against SessionContinuitySnapshot / TurnSnapshot

Intentionally deferred:

• Task Ledger integration
• Runtime Host integration
• model-visible Work Board tools
• recovery/graph state
• resultRefs
• automatic completion

Verification

• core + storage focused tests pass (30 tests)
• @maka/core and @maka/storage build/typecheck
• Biome clean
• migration: v0.1.6 fixture + exact v8 DDL -> real 8->9 path; old schema objects retained; partial indexes present
• archive-heavy list queries covered by EXPLAIN QUERY PLAN regression test against the production query builder
• cross-process CAS covered by a worker-thread test (one winner, one operation_conflict)

Checklist

• Phase 0 contract matches the maintainer-approved scope and deferrals
• Migration is additive (8 -> 9) with no user-data DROP
• Tests updated and passing
• Docs and PR description current

Refs #2560

[Astro-Han]

Thanks for defining the Work Board authority boundary before adding UI or Runtime integration.

Before getting into the implementation details, I think the product scope should be reconciled with the more recent decision in #2290. That discussion deliberately reduced the Session Task Ledger to a narrow Session-local Todo snapshot: no stable item identity, per-item CRUD, hierarchy, evidence, pagination, or workflow UI.

I understand that #2560 describes a different owner: Work Board items are user-owned, cross-Session deferred intentions, while SessionTodo is a model-authored progress snapshot. I am not suggesting that Work Board should reuse SessionTodo or the Task Ledger.

The remaining question is whether this distinct product surface needs a full Work Board domain yet. This PR introduces another durable task-like entity with stable IDs, per-item mutations, scopes, provenance variants, a state machine, archive/delete behavior, pagination, revisions, and future Session links—before there is a UI or production caller. That appears to reintroduce much of the product and maintenance complexity that #2290 has just removed from the existing task system.

Could we first establish why a minimal user-owned Todo list is insufficient for the actual problem of “remember this for later without interrupting the current Session”? A small vertical slice—capture, list, complete, and delete, with optional project/source context—would validate the user need without fixing the larger Board contract in schema v1. Session linking and execution projection could then be added when “start as task” has a real consumer.

If the broader Work Board scope remains intentional after that reconciliation, I found three implementation issues that seem worth resolving before the Phase 0 schema is published:

1. The revision check is outside the SQLite write transaction. Two processes can both read revision 1, both pass expectedRevision: 1, both write revision 2, and the later write silently overwrites the earlier semantic patch. Please make the read/check/write sequence one BEGIN IMMEDIATE transaction, or use conditional UPDATE/DELETE ... WHERE revision = ? statements and treat zero affected rows as a conflict.

2. The linked-session projector validates a new DTO rather than the canonical SessionContinuitySnapshot. It also uses Core TurnStatus, which rejects valid continuity states such as waiting_for_user and cancelled. Since there is no production consumer yet, the simplest option may be to defer this projector until it can live beside the real Runtime Host/Desktop continuity adapter instead of introducing a parallel contract now.

3. The new index does not satisfy the list ordering. The default unscoped query performs a full-table scan and temporary sort, while scoped queries still require a temporary sort for the final key because item_id has the opposite direction. Since the contract intentionally has no total item cap, pagination currently bounds returned rows but not query work. Please align the indexes with the actual scoped/unscoped query shapes before schema v9 is released.

The focused tests and current CI are green. I would also replace the fresh-database “migration” test with a real schema-8 upgrade fixture, but I see that as a verification improvement rather than a separate production finding.

简体中文

感谢你在增加 UI 或 Runtime 集成前，先明确 Work Board 的权威边界。

在讨论具体实现前，我认为这里的产品范围需要先与 #2290 中较新的决定重新对齐。该讨论刚刚把 Session Task Ledger 明确收缩为一个很窄的 Session-local Todo 快照：没有稳定的事项身份、逐项 CRUD、层级、证据、分页或 workflow UI。

我理解 #2560 定义的是另一个 owner：Work Board 是用户拥有的、跨 Session 的暂缓事项；SessionTodo 则是模型写入的进度快照。我并不是建议 Work Board 复用 SessionTodo 或 Task Ledger。

真正需要确认的是：这个独立的产品界面现在是否已经需要一套完整的 Work Board 领域模型。本 PR 在还没有 UI 和生产调用方时，就引入了另一个持久化的 task-like 实体，包括稳定 ID、逐项 mutation、scope、多种 provenance、状态机、归档/删除、分页、revision，以及未来的 Session 关联。这似乎重新引入了 #2290 刚从现有任务系统中删除的大量产品与维护复杂度。

我们是否应该先说明：对于“记住这个后续事项，但不要打断当前 Session”这一真实问题，为什么一个最小的、用户拥有的 Todo 列表还不够？先交付一条较小的纵向链路——保存、列出、完成和删除，并按需携带项目或来源上下文——就可以验证用户需求，而不必现在把更大的 Board contract 固化进 schema v1。等“启动为任务”出现真实消费者时，再增加 Session 关联和执行状态投影也不迟。

如果重新对齐后，完整的 Work Board 范围仍然是有意保留的，我还发现三个建议在发布 Phase 0 schema 前解决的实现问题：

1. revision 检查发生在 SQLite 写事务之外。两个进程可以同时读到 revision 1，都通过 expectedRevision: 1，然后分别写入 revision 2；后写入的 semantic patch 会静默覆盖前一次修改。建议把读取、检查和写入放进同一个 BEGIN IMMEDIATE 事务，或者使用带 WHERE revision = ? 条件的 UPDATE/DELETE，并将影响行数为零视为冲突。

2. linked-session projector 校验的是一套新定义的 DTO，而不是权威的 SessionContinuitySnapshot。它还使用了 Core TurnStatus，因此会拒绝 waiting_for_user、cancelled 等合法的 continuity 状态。当前还没有生产调用方，最简单的方案可能是先推迟这个 projector，等真实的 Runtime Host/Desktop continuity adapter 出现时再贴近实际 owner 实现，避免现在引入一份平行契约。

3. 新增索引不能满足 list 的实际排序。默认的无 scope 查询会全表扫描并临时排序；scoped 查询也会因为 item_id 的索引方向与查询相反，对最后一个排序键进行临时排序。由于契约明确不设置事项总量上限，目前分页只限制了返回行数，并没有限制每页查询的工作量。建议在 schema v9 发布前，让索引与 scoped/unscoped 查询的真实形态一致。

Focused tests 和当前 CI 均已通过。我还建议把“从空数据库创建 v9”的 migration 测试替换成真实的 schema 8 升级 fixture，不过这属于验证改进，不是独立的生产 finding。

AI-assisted review disclosure: Codex and Claude Opus were used to inspect the change and challenge the findings. I reproduced and adjudicated the issues above against the current source and own this review.

[somewan820]

Thanks for the review. I have verified all three implementation findings and fixed them in 476eb218b:

1. Revision CAS — update / archive / unarchive / remove now run the full read → revision check → write sequence inside one BEGIN IMMEDIATE transaction. The in-process write queue is retained for process-local serialization; the transaction closes the cross-process race. I confirmed the shared transaction helper flattens the nested #writeItem call, so there is no premature commit.

2. Linked-session projection — work-board-session-projection.ts (module, test, and package export) is removed. It was a parallel DTO validated with Core TurnStatus, which cannot represent waiting_for_user / cancelled from the canonical continuity contract. With no production consumer in Phase 0, I agree the projector should wait until Phase 3 and live beside the real Runtime Host / Desktop continuity adapter.

3. Indexes — schema v9 now ships (scope_kind, project_id, updated_at DESC, item_id DESC) and (updated_at DESC, item_id DESC). I verified against populated data with EXPLAIN QUERY PLAN: the default unscoped query, scoped queries (project and inbox), and both cursor forms use the indexes and no longer perform a full-table scan or temporary sort.

The migration test now builds a real schema-8 database from the released v0.1.6 operational-state fixture plus the exact v8 workflow DDL, then runs the actual 8→9 migration path and checks that the board table exists and the old schema objects remain.

On the product-scope question, I would like to separate PR fidelity from contract re-scoping:

• Fidelity to product(desktop): capture deferred work in a project-aware Work Board #2560: every semantic in this PR maps to the maintainer-approved Phase 0 contract from liugddx's review (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)) and the accepted revision (product(desktop): capture deferred work in a project-aware Work Board #2560 (comment)). Most of the surface you listed is load-bearing for that contract: pagination and archive/delete replaced the total-item cap the maintainer removed; revision/CAS was explicitly requested for concurrent renderer writes; provenance variants are required for side-chat capture to survive fork deletion; stable identity is the reference point Phase 3 "start as task" will need.

• RFC: Radically slim the Session Task Ledger #2290's Option 2 governs SessionTodo, not Work Board: the explicit-absent list in RFC: Radically slim the Session Task Ledger #2290 applies to the model-authored, Session-local progress snapshot. Work Board is a different owner (user-owned, cross-Session). Your own acceptance comment in RFC: Radically slim the Session Task Ledger #2290 states that product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 may proceed independently and should not become a P3 integration dependency of RFC: Radically slim the Session Task Ledger #2290 (RFC: Radically slim the Session Task Ledger #2290 (comment)).

The one item I agree has no Phase 0 consumer today is linkedSessions: the field exists in the schema, but Phase 0 has no mutation path that writes it and no UI or runtime caller reads it; Phase 3 "start as task" is the intended consumer. Rather than removing a maintainer-approved field unilaterally, I would like a decision.

@liugddx, could you please confirm:

(a) Does Phase 0 remain the approved contract after #2290 Option 2, or should it be re-scoped to capture / list / complete / delete with optional project and source context?

(b) Should linkedSessions stay in schema v1, or move to Phase 3 via a future additive migration?

(c) Is the linked-session projection formally deferred (removed from the Phase 0 deliverables), or do you want it implemented in Phase 0 against the canonical SessionContinuitySnapshot / TurnSnapshot?

I will not push further commits until these are resolved.

简体中文

感谢 review。三个实现问题我都已核验并在 476eb218b 修复：

1. Revision CAS：update / archive / unarchive / remove 现在把“读取 → revision 校验 → 写入”完整放进同一个 BEGIN IMMEDIATE 事务。进程内 write queue 保留用于单进程串行化；事务关闭跨进程竞争窗口。我已确认共享事务助手会扁平化嵌套的 #writeItem 调用，不会提前提交。

2. Linked-session projection：work-board-session-projection.ts（模块、测试、package export）已删除。它是一套平行 DTO，用 Core TurnStatus 校验，无法表达 canonical continuity 中的 waiting_for_user / cancelled。Phase 0 没有生产消费者，我同意推迟到 Phase 3，并放到真实 Runtime Host / Desktop continuity adapter 旁边实现。

3. 索引：schema v9 现在包含 (scope_kind, project_id, updated_at DESC, item_id DESC) 和 (updated_at DESC, item_id DESC)。我用真实填充数据跑了 EXPLAIN QUERY PLAN：默认 unscoped 查询、scoped 查询（project 与 inbox）以及两种 cursor 形态都使用索引，不再全表扫描或临时排序。

Migration 测试现在用发布的 v0.1.6 operational-state fixture + 精确的 v8 workflow DDL 构造真实 schema-8 库，走完整 8→9 迁移路径，并断言新表存在、旧 schema 对象保留。

关于产品范围问题，我想把“PR 是否忠实”和“契约是否要重新收缩”分开：

• 对 product(desktop): capture deferred work in a project-aware Work Board #2560 的忠实度：本 PR 的每个 semantic 都能对应 liugddx 的 maintainer review（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294753604）和已接受的修订版（https://github.com/maka-agent/maka-agent/issues/2560#issuecomment-5294956443）。你点名的多数复杂度都是该契约的承重结构：分页和 archive/delete 替代了 maintainer 移除的总上限；revision/CAS 是并发 renderer 写入的明确要求；provenance variants 是 side-chat 捕获在 fork 删除后仍可追溯的验收条件；stable identity 是 Phase 3 “start as task” 需要的引用点。

• RFC: Radically slim the Session Task Ledger #2290 Option 2 约束的是 SessionTodo，不是 Work Board：RFC: Radically slim the Session Task Ledger #2290 的 explicitly-absent 列表针对 model-authored、Session-local 的进度快照。Work Board 是不同的 owner（user-owned、cross-Session）。你在 RFC: Radically slim the Session Task Ledger #2290 的接受评论里也明确写了 product(desktop): capture deferred work in a project-aware Work Board #2560 Phase 0 可以独立推进，不应成为 RFC: Radically slim the Session Task Ledger #2290 的 P3 集成依赖（https://github.com/maka-agent/maka-agent/issues/2290#issuecomment-5298957426）。

我唯一同意“Phase 0 没有消费者”的是 linkedSessions：字段在 schema 里，但 Phase 0 没有任何 mutation 路径写入它，也没有 UI 或 runtime 调用方读取；Phase 3 “start as task” 才是消费者。与其单方面删除 maintainer 已批准的字段，我希望得到一个明确决定。

@liugddx 能否确认：

(a) #2290 Option 2 之后，Phase 0 是否仍然以已批准契约为准，还是收缩为 capture / list / complete / delete + 可选的 project/source context？

(b) linkedSessions 留在 schema v1，还是移到 Phase 3（未来 additive migration）？

(c) linked-session projection 是否正式推迟（从 Phase 0 交付物移除），还是要求在 Phase 0 基于 canonical SessionContinuitySnapshot / TurnSnapshot 实现？

在得到答复前我不会再 push 新 commit。

[liugddx]

Thanks for addressing Astro-Han's review carefully. I rechecked the updated implementation against the approved #2560 Phase 0 contract and the later #2290 Option 2 boundary.

My maintainer decisions are:

1. Phase 0 remains an independently approved Work Board contract.#2290 Option 2 narrows the model-authored, Session-local SessionTodo; it does not re-scope the user-owned, cross-Session Work Board into the same domain. The broader Phase 0 contract therefore does not need to be reduced to a generic Todo list solely because of #2290.
2. Move linkedSessions to Phase 3. It has no Phase 0 consumer, and it is already exposed as writable input through CreateWorkBoardItemInput and persisted by the create normalizer, so it is not merely a harmless reserved field. An additive migration when “start as task” has a real caller is the smaller and safer compatibility commitment.
3. The linked-session projection is formally deferred to Phase 3. Removing the parallel DTO was correct. Implement it beside the real Runtime Host/Desktop continuity adapter against canonical SessionContinuitySnapshot / TurnSnapshot facts when the consumer exists.

The CAS fix is correct: the read, revision check, and write now share one BEGIN IMMEDIATE transaction. The schema-8 upgrade fixture is also a meaningful improvement.

One implementation issue remains before merge: the index fix removes the temporary sort but does not bound filtering work for the default query. list() adds archived = 0, while neither ordering index contains archived. With an unbounded number of archived rows and few active rows, SQLite may still walk most of the ordering index to produce one active page. EXPLAIN QUERY PLAN reporting an index scan and no temporary B-tree does not disprove that scan cost.

Please add active-row partial indexes for both unscoped and scoped query shapes (or an equivalent design), and cover the archive-heavy case. After removing linkedSessions from the Phase 0 contract/store/tests and closing this remaining query-cost hole, the PR will match the approved authority boundary and be ready for another pass.

简体中文

感谢你认真处理 Astro-Han 的评审。我重新对照了已批准的 #2560 Phase 0 契约和后续 #2290 Option 2 的权威边界。

我的 maintainer 决策如下：

1. Phase 0 继续作为独立批准的 Work Board 契约推进。#2290 Option 2 收缩的是模型写入、Session-local 的 SessionTodo，并没有把用户拥有、跨 Session 的 Work Board 收缩进同一个领域。因此，不能仅因为 #2290 就把完整 Phase 0 再缩成普通 Todo 列表。
2. linkedSessions 移到 Phase 3。 Phase 0 没有消费者，而且它已经通过 CreateWorkBoardItemInput 暴露为可写输入，并由 create normalizer 持久化，所以它并不是一个无害的预留字段。等“启动为任务”出现真实调用方时，通过增量迁移增加，是更小、更安全的兼容性承诺。
3. linked-session projection 正式推迟到 Phase 3。 删除平行 DTO 是正确的。等真实消费者出现时，再放到 Runtime Host/Desktop continuity adapter 旁，基于规范的 SessionContinuitySnapshot / TurnSnapshot 事实实现。

CAS 修复成立：读取、revision 校验和写入现在位于同一个 BEGIN IMMEDIATE 事务中。真实 schema-8 升级 fixture 也是有意义的改进。

合并前还剩一个实现问题：索引修复消除了临时排序，但没有限制默认查询的过滤工作量。list() 会添加 archived = 0，但两个排序索引都不包含 archived。当归档记录无上限、活动记录很少时，SQLite 为返回一页活动事项仍可能遍历排序索引中的大多数记录。EXPLAIN QUERY PLAN 显示使用索引且没有临时 B-tree，并不能证明扫描成本受限。

请为 scoped 和 unscoped 的活动项查询增加 partial indexes（或等价设计），并覆盖“绝大多数记录已归档”的情况。删除 Phase 0 contract/store/tests 中的 linkedSessions，并补齐这个查询成本缺口后，本 PR 就能符合已批准的权威边界，可以进入下一轮评审。

📝 Walkthrough

Summary

• Problem solved

  • Adds the Phase 0 Work Board contract and durable SQLite storage.
  • Supports validated item creation, updates, listing, archiving, restoring, and removal.
  • Adds bounded cursor pagination, provenance checks, lifecycle invariants, semantic patches, and revision-based optimistic concurrency.
  • Detects corrupt records and rejects invalid scope, project, revision, timestamp, and archive data.

• Source of truth

  • Extends the existing packages/core contract and packages/storage SQLite workflow schema.
  • Does not create a parallel linked-session path. linkedSessions and linked-session projection remain deferred to Phase 3.

• Implementation scope

  • Provides the smallest coherent Phase 0 solution.
  • BEGIN IMMEDIATE transactions and the process-local write queue are necessary for serialized mutations and revision checks.
  • Schema migration 8→9 and active, scoped, cursor, and archive indexes support compatibility and query performance.

• Simplification

  • The removed linked-session projection does not reduce Phase 0 behavior or regression coverage.
  • Task Ledger, Runtime Host, model-visible tools, recovery state, result references, and automatic completion remain outside this change.
  • No further deletion or simplification is apparent without weakening behavior or regression coverage.

• Risks and validation

  • Main risks include migration compatibility, concurrent revision conflicts, pagination correctness, SQLite constraint enforcement, timestamp ordering, cursor scope binding, and corrupt-record detection.
  • Tests cover contract behavior, storage operations, worker-thread and cross-process CAS races, pagination, query plans, corruption, constraints, migration, and backup/restore.
  • Reported validation includes passing focused tests, successful builds and typechecks for both packages, and clean Biome checks.
  • Required-check status remains unverified because no direct repository check result is available.

Review-relevant risks

• The PR changes public packages/core and packages/storage exports and adds a durable SQLite schema migration. These are public-contract and release-affecting changes. Material changes in these areas require independent human review under repository policy.
• The PR changes persisted data behavior, including archive-before-delete enforcement, scope/project constraints, migrations, and corruption handling. These changes can affect user data and operational recovery. Material changes in these areas require independent human review under repository policy.
• No security, licensing, or governance effect was identified in the current diff.
• The person performing the merge reviews the final diff. A maintainer makes the final determination.

Thanks for the maintainer decisions. I've applied them in 833481e64:

• linkedSessions is removed from the Phase 0 contract, create input, store, and tests. The Phase 0 normalizer and decoder now reject the field (fail-closed), and the contract doc records it as a Phase 3 addition.
• The linked-session projection stays deferred to Phase 3, documented in the contract and the PR description.
• Active-row partial indexes were added for both default query shapes: workflow_work_board_items_active_order and workflow_work_board_items_active_scope_order (both WHERE archived = 0). The existing full ordering indexes remain for includeArchived queries.
• Archive-heavy coverage: the new storage test creates 120 archived + 6 active items, asserts list behavior, and verifies via EXPLAIN QUERY PLAN that default unscoped and scoped queries use the partial indexes without a temporary sort. The migration test also asserts both partial indexes exist after the 8→9 upgrade.

Verification: core + storage focused tests pass (26 tests), both packages build/typecheck, Biome is clean.

The PR is now ready for review. Let me know if you'd like any further adjustments.

感谢 maintainer 的决定。我已在 833481e64 全部落地：

• linkedSessions 已从 Phase 0 契约、create input、store 和测试中移除；Phase 0 的 normalizer 和 decoder 现在会拒绝该字段（fail-closed），契约文档记录为 Phase 3 加入。
• linked-session projection 保持推迟到 Phase 3，已写入契约文档和 PR description。
• 为两种默认查询形态新增 active-row partial index：workflow_work_board_items_active_order 和 workflow_work_board_items_active_scope_order（均为 WHERE archived = 0）；原有全量排序索引保留给 includeArchived 查询。
• Archive-heavy 覆盖：新增 storage 测试构造 120 条 archived + 6 条 active，断言 list 行为，并用 EXPLAIN QUERY PLAN 验证默认 unscoped/scoped 查询使用 partial index、无临时排序；migration 测试同时断言 8→9 升级后两个 partial index 存在。

验证：core + storage focused tests 全部通过（26 个），两个包 build/typecheck 通过，Biome 干净。

A corrupt row can never be deleted.

remove calls #requireItem, which decodes the row and throws corrupt_record when record_json is unparseable or disagrees with the indexed columns. The fail-closed read is correct, but it also blocks the only removal path. A user who hits a corrupt item cannot repair the board.

Add a repair path. One option is to allow deletion when expectedRevision matches the indexed revision column, without decoding record_json.

The cursor does not bind to the query filters.

encodeCursor stores only updatedAt and itemId. A cursor returned by an inbox-scoped page decodes successfully and applies without complaint to a project-scoped query or to an includeArchived: true query. The caller then receives a page that looks coherent but silently starts from an unrelated position in a different result set.

Include a filter fingerprint in the cursor payload, and reject a cursor whose fingerprint does not match the current query.

Bind the query-plan assertions to the store's own SQL.

The test hand-writes the list SQL. The store builds its list SQL internally. The assertions therefore prove only that the indexes serve this copy of the query. If the store query later changes its filter shape, ORDER BY, or limit, this test stays green while the production path falls back to a scan or a temp sort.

Export the query text (or a small explainListPlan helper) from work-board-store.ts and assert the plan for that exact string.

packages/core/src/work-board.ts:494

• Unarchive can currently decrease updatedAt if now is earlier than the stored updatedAt (e.g. wall clock skew). Because list ordering/pagination uses updatedAt, clamp this to keep timestamps monotonic (see e.g. sqlite-long-term-memory-store.ts:953).

 item: {
...activeFields,
archived: false,
updatedAt: now,
revision: item.revision + 1,
},

packages/core/src/work-board.ts:476

• Archive timestamps should be monotonic even if the wall clock moves backwards; otherwise an archive mutation can decrease updatedAt and break ordering/pagination. Consider clamping both archivedAt and updatedAt to at least the current item.updatedAt (consistent with other storage authorities).

 ...item,
archived: true,
archivedAt: now,
updatedAt: now,
revision: item.revision + 1,

packages/core/src/work-board.ts:460

• updatedAt can move backwards if the caller clock moves backwards (or a test/consumer passes an older now). Since list pagination/orders are keyed on updatedAt, a decreasing timestamp can cause incorrect ordering and cursor paging anomalies. Other stores clamp mutation timestamps to be monotonic (e.g. packages/storage/src/sqlite-long-term-memory-store.ts:953, packages/storage/src/managed-secret-store.ts:430-432).

This issue also appears in the following locations of the same file:

• line 472
• line 489

 ...(notes === undefined ? {} : { notes }),
scope,
state,
updatedAt: now,
revision: item.revision + 1,
},

Thanks for working through the earlier review rounds. I rechecked the current head, including the Core contract, SQLite lifecycle, migration, indexes, existing feedback, and focused store tests. The earlier CAS, linked-session projection, indexing, notes-patch, and migration-fixture findings are resolved.

I left three inline P2 comments covering exact-shape validation, monotonic mutation timestamps, and cursor/filter binding. None is a P0/P1, and I do not think this needs a broader redesign or PR split.

Two non-blocking test-truth follow-ups:

• The concurrent-mutation test uses one store, so it proves process-local serialization but would still pass without the cross-process BEGIN IMMEDIATE fix. I would keep it and name it accordingly; a worker/barrier test can cover cross-process CAS if that guarantee needs executable protection.
• The query-plan test is valuable, but it explains a handwritten copy of the list SQL rather than the SQL produced by list(). Sharing an internal query builder would keep the regression test tied to production without adding a public API.

I would keep the remaining contract, persistence, migration, archive, backup, and index tests; they cover distinct lifecycle seams rather than duplicating one another. Overall, the Work Board / SessionTodo authority split is sound, and the current Phase 0 scope is appropriately reduced.

中文对照

感谢持续处理前几轮 review。我重新检查了当前 head，包括 Core 契约、SQLite 生命周期、migration、索引、已有反馈和聚焦的 store 测试。之前的 CAS、linked-session projection、索引、notes patch 和 migration fixture 问题都已经解决。

我留下了三条 inline P2，分别涉及：

• 对 Work Board item 和 mutation input 进行 exact-shape 校验，避免未知字段被静默接受或在下一次写入时丢失；
• 在持久化事务中保持 mutation timestamp 单调，避免系统时钟回拨破坏 keyset pagination；
• 将 opaque cursor 与规范化后的 scope / includeArchived filters 绑定，避免跨结果集复用时静默漏项。

它们都不是 P0/P1，也不需要扩大成整体重构或拆分 PR。

另外有两项非阻塞的测试真实性建议：

• 当前并发 mutation 测试使用同一个 store，因此证明的是进程内串行化；即使没有跨进程 BEGIN IMMEDIATE 修复，它仍会通过。建议保留并让测试名称准确表达该范围；如需可执行地保护跨进程 CAS，再补 worker/barrier 测试。
• Query-plan 测试有价值，但它解释的是手写的 list SQL 副本，而不是 list() 实际生成的 SQL。共享内部 query builder 可以防止测试与生产查询逐渐漂移，同时不需要扩大公共 API。

其余 contract、persistence、migration、archive、backup 和 index 测试覆盖不同生命周期，不建议删除。总体而言，Work Board 与 SessionTodo 的权威边界正确，Phase 0 的当前范围也已经合理收缩。

The final findings were verified against the current PR head.

packages/storage/src/work-board-store.ts:358

• workBoardFilterFingerprint embeds the full projectId (max 160 chars) into filterFingerprint, but decodeCursor rejects fingerprints longer than 128 and the contract bounds cursor strings to 256 chars. For long project IDs this will produce an overlong cursor (and/or an undecodable cursor), causing pagination to fail after the first page with "cursor does not match the list filters".

@somewan820 Verified.

• The cursor test now confirms that the second page has a different item ID.
• WorkBoardStore.list() and the query-plan test both use buildWorkBoardListStatement.
• The migration guard returns before migrateSqliteWorkflowDatabase on a current target schema. The DROP INDEX does not run on normal opens.

The remaining implementation findings are addressed. The index-rebuild finding remains withdrawn.
🐇 ✅

Timestamp: 2026-08-15T09:42:04.215Z
Learning: In `packages/storage/src/sqlite-workflow-schema.ts`, `migrateSqliteWorkflowDatabase` intentionally drops and recreates `workflow_work_board_items_scope_order`. An intermediate Phase 0 development build created the same index name with `item_id ASC` while registering schema version 9. `inspectAndMigrateOperationalState` only runs this migration when the schema registry or target schema does not match, so the drop executes only during migration. SQLite `CREATE INDEX IF NOT EXISTS` cannot replace the old same-name index definition.

packages/storage/src/tests/fixtures/work-board-cas-worker.ts:15

• With threadId imported, prefer it over process.pid for the per-worker title suffix (worker threads share a PID).

 { title: `worker-${process.pid}` },

packages/storage/src/tests/work-board-store.test.ts:352

• This test name says “cross-process”, but it uses Worker from node:worker_threads, which is cross-thread (same process) rather than cross-process. Either rename the test to match what it actually exercises, or switch to a child-process based worker if you truly need a cross-process regression.

 test('cross-process CAS produces exactly one winner and one conflict', async () => {

packages/storage/src/tests/fixtures/work-board-cas-worker.ts:1

• If you keep using worker threads here, process.pid is the same across all workers, which makes the “winner” update harder to distinguish when debugging. Importing and using threadId gives each worker a unique identifier within the process.

This issue also appears on line 15 of the same file.

import { parentPort, workerData } from 'node:worker_threads';

Follow-up: I reviewed the current head (688051767). The requested Phase 0 scope changes, active-row partial indexes with archive-heavy coverage, and Astro-Han’s subsequent P2 findings are resolved. The remaining test-truth caveat is non-blocking. This PR is ready to merge.

[liugddx]

Approved. The current head satisfies the approved Phase 0 contract and resolves the outstanding review findings.

[Astro-Han]

Thanks for carrying the earlier review rounds through to a coherent Phase 0 boundary. I rechecked the current head after the maintainer approval, including the Core contract, SQLite lifecycle, migration/index paths, prior feedback, and focused tests.

The previous CAS transaction, linked-session deferral, active-row indexes, monotonic mutation timestamps, filter-bound cursors, and cursor-size fixes all hold. I found two remaining runtime-boundary gaps and left them inline:

• create/stored notes still accepts null even though that clear signal belongs only to update patches;
• unknown mutation-option keys can silently disable expectedRevision CAS.

Both are narrow exact-validation fixes at the existing owners. They do not call for reopening the product scope, redesigning the store, or splitting this PR.

Focused verification on 688051767:

• @maka/core build: passed
• @maka/storage build: passed
• Work Board storage test file: 17/17 passed
• visible GitHub checks: green

Once the two inline issues are addressed, this should only need a quick final pass.

感谢把前几轮 review 收敛成连贯的 Phase 0 边界。我在 maintainer Approve 之后重新检查了同一个当前 head，包括 Core 契约、SQLite 生命周期、migration/index、已有反馈和聚焦测试。

此前的 CAS 事务、linked-session 推迟、active partial indexes、mutation 时间戳单调性、游标与过滤条件绑定，以及游标长度问题都已经正确解决。

目前还剩两个运行时边界缺口，已分别留下 inline comment：create/持久化记录仍会接受 notes: null；mutation options 的未知字段可能静默关闭 expectedRevision CAS。两者都只需要在现有 owner 上补齐精确校验，不需要重新讨论产品范围、重构 store 或拆分 PR。

当前 head 的 Core/Storage 构建通过，Work Board storage 聚焦测试 17/17 通过，GitHub 可见检查全绿。处理完两条 inline 后，快速复核即可。

AI-assisted review: Codex performed the primary review and executable reproductions; four independent Codex reviewers adversarially checked the Core contract, SQLite lifecycle, migration/test evidence, and overall architecture. The findings above were adjudicated against the current PR head. The human reviewer remains responsible for the final review and merge decision.

Astro-Han — both P2 inline comments are fixed in cbf2dc64a (details in the threads):

• notes: null is now rejected in create input and stored records; null remains the explicit clear signal only in update patches.
• Mutation options are validated as an exact-shape object, so unknown keys like expectedRevison or extra fields throw invalid_input instead of silently disabling expectedRevision CAS.

Verification: core + storage focused tests pass (33 tests), both packages build/typecheck, Biome clean. liugddx already approved the prior head; the new commit only contains these two narrow validation fixes.

Could you take the quick final pass? If everything looks good, this PR is ready to merge. @liugddx — happy to merge once Astro-Han confirms.

简体中文

Astro-Han —— 两条 P2 代码评论已在 cbf2dc64a 修复（详见对应线程）：

• create input 和已存记录现在拒绝 notes: null；null 只保留为 update patch 的显式清除信号。
• mutation options 改为精确形状校验，expectedRevison 这类拼写错误或多余字段会直接 invalid_input，不会再静默关闭 expectedRevision CAS。

验证：core + storage focused tests 全部通过（33 个），两个包 build/typecheck 通过，Biome 干净。liugddx 已对前一版 head 表示 approve；本次新 commit 只包含这两处窄校验修复。

能否做最后一次快速复核？如果没问题，这个 PR 就可以合并了。@liugddx —— Astro-Han 确认后就可以 merge。

[Astro-Han]

Thanks for the quick follow-up. I rechecked the current head (cbf2dc64a) and both remaining P2 findings are resolved:

• create input and durable records now reject notes: null, while update patches retain null as the explicit clear signal;
• mutation options now fail closed on unknown keys, so a misspelled or extra field cannot silently disable expectedRevision CAS.

The regression tests exercise the real contract/store boundaries and verify that rejected mutation options leave the stored revision and state unchanged. I found no remaining P0–P3 issues.

The Phase 0 authority boundary remains intact: Core owns the item contract, Storage owns durable mutation and CAS, and no Runtime execution state or parallel authority has been introduced. The current solution is the smallest complete implementation of the approved scope; it does not need further restructuring or a PR split.

Verification on cbf2dc64a:

• @maka/core build and focused Work Board tests: 15/15 passed
• @maka/storage build and focused Work Board tests: 18/18 passed
• Biome formatting check on the four changed files: passed
• git diff --check: passed
• visible GitHub checks: green
• merge state: clean

Approved from my side.

感谢快速处理。我重新检查了当前 head（cbf2dc64a），最后两条 P2 都已解决：

• create input 和持久化记录现在拒绝 notes: null，同时 update patch 仍保留 null 作为显式清除信号；
• mutation options 现在会拒绝未知字段，因此拼错或多余字段不会再静默关闭 expectedRevision CAS。

回归测试覆盖了真实的契约和 store 边界，并验证 mutation options 被拒绝后，持久化 revision 和 state 都不会变化。目前没有剩余 P0–P3。

Phase 0 的权威边界保持清晰：Core 负责 item contract，Storage 负责持久化 mutation 与 CAS，没有引入 Runtime 执行状态副本或平行 authority。当前方案已经是已批准范围内的最小完整实现，不需要继续重构或拆分 PR。

当前 head 的 Core/Storage build 通过，聚焦测试分别为 15/15 与 18/18，Biome、git diff --check 和 GitHub checks 均通过，merge state 为 clean。

我这边 approve。
