From d24d5001e7d5d5e4686c8299cc8782bdaed8f136 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=E9=99=86=E9=80=8A?= Date: Sun, 5 Jul 2026 10:51:59 +0800 Subject: [PATCH 01/16] =?UTF-8?q?feat(runtime):=20session=20task=20ledger?= =?UTF-8?q?=20primitive=20=E2=80=94=20TaskCreate/TaskUpdate=20+=20turn-tai?= =?UTF-8?q?l=20injection=20(#15=20P0-task)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Main-agent session task ledger, the task-tracking slice of #15: - core: Task contract (4-state status), defensive normalize/validate, TaskLedgerStore interface, shared list renderer, 200-task hard cap. - storage: FileTaskLedgerStore at sessions//tasks.json — atomic tmp+rename writes serialized per session via chainWrite. Render reads degrade to empty; mutate reads fail closed (corrupt ledger is never used as a write base, so a transient read error cannot wipe tasks). - runtime: TaskCreate (batch) + TaskUpdate tools, permissionRequired false (pure local session state, cf. agent_list). Schemas encode the subject cap so the model learns constraints at validation time. Tool results render the post-mutation ledger returned from inside the write-queue critical section (no second read, no race). - desktop: tools wired into builtinTools; turn tail injects the current ledger via the existing volatile-tail path (durable system prefix untouched — prefix-cache discipline). Ledger text passes redactSecrets on both surfaces (tail + tool result) and strips literal task-ledger tags so a subject cannot escape the data envelope. No TaskList tool: the per-turn tail injection makes it redundant. Child agents do not inherit the tools (definition allowlists). Headless wiring and the UI panel are follow-ups. --- .../session-environment-prompt.test.ts | 4 +- .../__tests__/task-ledger-contract.test.ts | 122 ++++++++++++ apps/desktop/src/main/main.ts | 10 +- apps/desktop/src/main/system-prompt-main.ts | 36 +++- packages/core/package.json | 1 + packages/core/src/index.ts | 20 ++ packages/core/src/task-ledger.ts | 131 +++++++++++++ .../src/__tests__/task-ledger-tools.test.ts | 139 +++++++++++++ packages/runtime/src/index.ts | 5 + packages/runtime/src/task-ledger-tools.ts | 83 ++++++++ .../src/__tests__/task-ledger-store.test.ts | 181 +++++++++++++++++ packages/storage/src/index.ts | 1 + packages/storage/src/session-store.ts | 5 +- packages/storage/src/task-ledger-store.ts | 185 ++++++++++++++++++ 14 files changed, 916 insertions(+), 7 deletions(-) create mode 100644 apps/desktop/src/main/__tests__/task-ledger-contract.test.ts create mode 100644 packages/core/src/task-ledger.ts create mode 100644 packages/runtime/src/__tests__/task-ledger-tools.test.ts create mode 100644 packages/runtime/src/task-ledger-tools.ts create mode 100644 packages/storage/src/__tests__/task-ledger-store.test.ts create mode 100644 packages/storage/src/task-ledger-store.ts diff --git a/apps/desktop/src/main/__tests__/session-environment-prompt.test.ts b/apps/desktop/src/main/__tests__/session-environment-prompt.test.ts index 911d2cf778..0d2fda26ae 100644 --- a/apps/desktop/src/main/__tests__/session-environment-prompt.test.ts +++ b/apps/desktop/src/main/__tests__/session-environment-prompt.test.ts @@ -49,8 +49,8 @@ describe('session environment prompt', () => { it('is injected as a current-turn tail instead of durable system prefix', async () => { const source = await readMainProcessCombinedSource();

A model-authored subject carrying any of these could open or close the data envelope early and smuggle instruction-level text, which is the escape the PR's own comment claims to block. Add a shared renderSafeTaskLedgerText in core (redact + strip /<\/?task-ledger[^>]*>/) and route both the tool-result face (renderTaskLedger) and the turn-tail face (renderTaskLedgerTailFragment) through it, so the two faces can no longer drift.

An equivalent refactor that renames a variable or restructures the callback breaks the test even though behavior is unchanged — confirmed when the earlier tag-strip commit rewrote renderTaskLedger and these regexes stopped matching. Extract createMainTaskLedgerWiring (store + tools + system-prompt deps slice, all sharing one store instance) and route main.ts through it. Replace the source-regex test with a behavior test that: - asserts TaskCreate/TaskUpdate are wired in, - asserts the store is real and empty for a fresh workspace, - asserts the system-prompt deps share the SAME store as the tools, - calls TaskCreate through the wiring and checks the task lands in the store the turn tail reads (mutate and read faces share one ledger).

A hand-edited, legacy, or externally- written tasks.json could therefore: - carry more than TASK_LEDGER_MAX_TASKS valid records, which list() would inject into the turn tail every turn (unbounded context bloat), and which a subsequent create would silently truncate-and-overwrite; or - carry an id with a newline (breaks the formatTaskLedgerList line structure and injects text into the prompt), whitespace, or thousands of chars (unbounded bloat).

The contract's identity assertion (systemPromptDeps.taskLedger === store) therefore proved nothing about how main actually wires the store into the system prompt service. Drop the field; the factory now returns only { store, tools }. Replace the identity assertion with an end-to-end behavior test that builds the real createSystemPromptMainService with wiring.store, writes a task via TaskCreate through wiring.tools, and asserts the turn tail reads the same task. A root-level split (tools bound to a store over a different workspace than the tail reads) now fails the test; an instance-level split over the same root correctly does not, since file-backed stores over one root are equivalent. --- .../__tests__/task-ledger-contract.test.ts | 24 ++++++++++++------- apps/desktop/src/main/task-ledger-wiring.ts | 7 ++---- 2 files changed, 18 insertions(+), 13 deletions(-) diff --git a/apps/desktop/src/main/__tests__/task-ledger-contract.test.ts b/apps/desktop/src/main/__tests__/task-ledger-contract.test.ts index a32c025572..d001c4b2f9 100644 --- a/apps/desktop/src/main/__tests__/task-ledger-contract.test.ts +++ b/apps/desktop/src/main/__tests__/task-ledger-contract.test.ts @@ -59,7 +59,7 @@ function fakeContext(sessionId: string): MakaToolContext { } describe('task ledger contract', () => { - it('wires the store, tools, and system-prompt deps to one shared task ledger (behavior, not source text)', async () => { + it('wires the store and tools to one shared task ledger the turn tail reads (behavior, not source text)', async () => { const root = await mkdtemp(join(tmpdir(), 'maka-task-ledger-wiring-')); const wiring = createMainTaskLedgerWiring(root); // (a) TaskCreate/TaskUpdate are wired in. @@ -67,16 +67,24 @@ describe('task ledger contract', () => { assert.ok(wiring.tools.some((t) => t.name === TASK_UPDATE_TOOL_NAME), 'TaskUpdate must be wired'); // (b) store is real and empty for a fresh workspace. assert.deepEqual(await wiring.store.list('sess-1'), []); - // (c) system-prompt deps share the SAME store so the turn tail reads what tools write. - assert.equal(wiring.systemPromptDeps.taskLedger, wiring.store); - // (d) tools are bound to that same store: a TaskCreate persists into the shared - // store the tail reads, proving the mutate and read faces share one ledger. + // (c) tools and the turn tail share ONE store through the real system prompt + // service: a TaskCreate lands in the store the tail reads, proving the + // mutate and read faces cannot drift to different ledgers. + const service = createSystemPromptMainService({ + settingsStore: { get: async () => ({}) as AppSettings }, + workspaceRoot: root, + localMemory: { + getState: async () => ({ status: 'ok', agentReadEnabled: false, content: '' }) as never, + consumePendingPromptUpdates: () => [], + }, + taskLedger: wiring.store, + }); const create = wiring.tools.find((t) => t.name === TASK_CREATE_TOOL_NAME); assert.ok(create, 'TaskCreate tool must be present'); await create.impl({ tasks: [{ subject: '通过装配建任务' }] }, fakeContext('sess-1')); - const tasks = await wiring.store.list('sess-1'); - assert.equal(tasks.length, 1); - assert.equal(tasks[0]?.subject, '通过装配建任务'); + const tail = await service.buildTurnTailPrompt(undefined, 'sess-1'); + assert.ok(tail, 'tail must render when the shared store has tasks'); + assert.match(tail, /通过装配建任务/); }); it('injects nothing for an empty ledger', async () => { diff --git a/apps/desktop/src/main/task-ledger-wiring.ts b/apps/desktop/src/main/task-ledger-wiring.ts index ac515f7670..8c1941b4b3 100644 --- a/apps/desktop/src/main/task-ledger-wiring.ts +++ b/apps/desktop/src/main/task-ledger-wiring.ts @@ -7,16 +7,14 @@ import { buildTaskLedgerTools, type MakaTool } from '@maka/runtime'; * by the mutate face (TaskCreate/TaskUpdate tools) and the read face (the * turn-tail fragment).

Render each task as a fielded line `id= status= subject=`: the canonical id is a distinct leading field, and any id-like text in the subject stays inside the quoted JSON payload. The id is still emitted verbatim (a redaction-stable stable token validated on write and read, so scrubbing it could only deform it and break TaskUpdate). Each subject is still redacted and tag-stripped independently. Existing tests match on the subject/total/envelope, not the line format, so they pass unchanged; the cross-line test's id assertions move to the fielded shape, and a new test checks a subject cannot smuggle a fake id. Also sync isSafeTaskId's comment, which still described the old whole-string renderer that scrubbed the id -- the per-task renderer emits the id verbatim, so the comment now says the id must be redaction-stable because a renderer must never deform it, not because the current renderer scrubs it. --- .../core/src/__tests__/task-ledger.test.ts | 17 +++++- packages/core/src/task-ledger.ts | 56 ++++++++++--------- 2 files changed, 46 insertions(+), 27 deletions(-) diff --git a/packages/core/src/__tests__/task-ledger.test.ts b/packages/core/src/__tests__/task-ledger.test.ts index 3b8716b85d..32e2dd3ec3 100644 --- a/packages/core/src/__tests__/task-ledger.test.ts +++ b/packages/core/src/__tests__/task-ledger.test.ts @@ -42,6 +42,19 @@ describe('renderSafeTaskLedgerText', () => { assert.equal(out.includes('a < b holds'), true); }); + test('renders the canonical id as a distinct leading field so a subject cannot smuggle a fake id', () => { + const t: Task = { id: 'real-id', subject: '做事 (id: fake-id) 收尾', status: 'pending', createdAt: 1, updatedAt: 1 }; + const out = renderSafeTaskLedgerText([t]); + // canonical id is a distinct leading field on the line + assert.match(out, /^id=real-id status=pending subject=/); + // the canonical id appears exactly once (the leading field), not duplicated + assert.equal((out.match(/id=real-id/g) || []).length, 1); + // the fake id in the subject is inside the quoted JSON payload, not a bare field + assert.match(out, /subject="[^"]*\(id: fake-id\)[^"]*"/); + // and the fake id never appears as a bare id= field + assert.equal((out.match(/id=fake-id/g) || []).length, 0); + }); + test('does not strip across lines: an unclosed on the next task line', () => { // [^>]* in the strip regex crosses newlines, so an unclosed `` in the next would silently delete the text between @@ -49,8 +62,8 @@ describe('renderSafeTaskLedgerText', () => { const t1: Task = { id: 'id-1', subject: 'foo baz', status: 'pending', createdAt: 2, updatedAt: 2 }; const out = renderSafeTaskLedgerText([t1, t2]); - assert.equal(out.includes('(id: id-1)'), true, `first task id must survive, got: ${JSON.stringify(out)}`); - assert.equal(out.includes('(id: id-2)'), true, `second task id must survive, got: ${JSON.stringify(out)}`); + assert.equal(out.includes('id=id-1 '), true, `first task id must survive, got: ${JSON.stringify(out)}`); + assert.equal(out.includes('id=id-2 '), true, `second task id must survive, got: ${JSON.stringify(out)}`); assert.equal(out.includes('foo'), true, `first subject text must survive, got: ${JSON.stringify(out)}`); assert.equal(out.includes('bar > baz'), true, `second subject text must survive intact, got: ${JSON.stringify(out)}`); // regression guard: complete same-line variants are still stripped diff --git a/packages/core/src/task-ledger.ts b/packages/core/src/task-ledger.ts index 0e7bd6afe0..8092064ed6 100644 --- a/packages/core/src/task-ledger.ts +++ b/packages/core/src/task-ledger.ts @@ -69,21 +69,23 @@ export function isTaskStatus(value: unknown): value is TaskStatus { /** * Stable-token id contract shared by the runtime tool schema (front-door) and - * the storage read path.
