What

Merges block/buzz@main into our shared launchpad branch. This is the upstream sync that has been pending since PR #12 (2026-08-11) — 113 commits, 980 files, +108,497/−18,957.

Related issue

Refs #215 — this sync surfaced #215's pre-existing mobile-test failures again (see Verification), and the "Proposed follow-up" below asks for #215 to land before the next sync. No single issue tracks periodic upstream-sync chores themselves, so this PR completes no issue outright.

Issue type

Task

Why now

Notable upstream changes in this window:

Risk analysis

Real conflicts this time, unlike PR #12's zero-conflict merge. Four files had genuine overlap between upstream's changes and this fork's local delta — desktop/src-tauri/src/managed_agents/runtime.rs, desktop/src-tauri/src/managed_agents/runtime.rs's sibling restore.rs, .github/workflows/ci.yml, and AGENTS.md. git merge resolved all four with no conflict markers, and each was individually verified post-merge to still carry the fork's changes:

File Fork's change Verified present after merge
managed_agents/runtime.rs / restore.rs Dial the relay the caller actually configured, not the loopback-normalized key identity (relay_url.to_string(), "Dial the relay the caller actually configured" comments) grep confirms both survive
.github/workflows/ci.yml Fork-added "Changed-paths filter contract" CI step ✅ present
AGENTS.md The <!-- launchpad-26 fork: begin/end --> banner block ✅ present, contiguous

A second fix, made on top of the merge

The merge combined upstream's own growth of managed_agents/runtime.rs with the fork's local patch, pushing the file from 984 to 1008 lines — over the desktop file-size ratchet's 1000-line cap. Fixed in a follow-up commit (43366affa) by extracting persona-drift classification, workspace-pair-key resolution, and the ManagedAgentSummary builder into a new sibling module, runtime/summary.rs, following this file's existing convention of splitting into sibling modules (path, metadata, stop, sweep, process, orphan_sweep, instance_reaper, lifecycle). Purely mechanical — no behavior change.

Verification

Gate Result
Clean merge in an isolated worktree ✅ zero conflict markers (4 files auto-resolved, verified above)
cargo check --workspace ✅ 0 errors (2m33s)
just test-unit ✅ 9/9 suites — buzz-core, buzz-auth, buzz-voice, buzz-cli, buzz-db, buzz-conformance, buzz-push-gateway, buzz-backend-kubernetes, buzz-agent
just desktop-tauri-clippy (-D warnings, --all-targets) ✅ clean
File-size-ratchet fix: cargo check + clippy --all-targets + targeted tests ✅ 123/123 passed in managed_agents::runtime
Full pre-push gate (branch-skew, rust-tests, desktop-check, desktop-typecheck, desktop-test, desktop-tauri-checks) ✅ all six pass clean
mobile-test ⚠️ 4 failures — confirmed pre-existing, see below

mobile-test's 4 failures are pre-existing, not caused by this merge

Ran the same 4 tests against a fresh worktree of origin/launchpad's current tip (before any of this PR's changes) and got the identical failures:

forum_widgets_test.dart:       ForumPostCard constrains an older timestamp at large accessible text sizes
forum_widgets_test.dart:       ForumThreadPage constrains post and reply timestamps at large text sizes
compose_note_page_test.dart:   reply preview constrains its timestamp at large text sizes
note_card_test.dart:           constrains timestamp with agent and follow metadata

Same set PR #12 first documented on 2026-08-10 — all four assert timestamp layout at large accessible text sizes, text-metric/environment sensitive rather than a real regression. Tracked in #215 rather than left undocumented.

This PR was pushed with --no-verify (explicit approval given, since bypassing pre-push hooks otherwise requires it) — every other local gate passed clean, and mobile-test is the only one bypassed, for the reason above.

Local environment note (not a code issue)

This sandbox's cargo/libgit2 couldn't do ssh-agent auth for two pinned git dependencies (rust-s3, mesh-llm) — building locally required CARGO_NET_GIT_FETCH_WITH_CLI=true to shell out to system git, which already had working SSH auth. Anyone with a normal SSH agent won't hit this.

Please do not squash

Merge this with a merge commit. Squashing would flatten 113 upstream commits (plus the local file-size fix) into one opaque blob, destroying the shared history with block/buzz and making every future upstream sync conflict.

Proposed follow-up

atishpatel and others added 30 commits August 10, 2026 07:20
## Why
Selecting or typing a member whose display name extends another member's
name, such as `@Fast Fizz Codex`, could emit p-tags for both identities
and wake the wrong agent.

## What
- Resolve overlapping member-name matches by choosing the longest valid
display name at each mention offset
- Preserve separately typed short-name mentions at different offsets
- Add regression coverage for selected team expansions and manually
typed prefix collisions

## Risk Assessment
Low to medium — this changes Desktop mention routing only. Exact
mentions and distinct offsets remain supported; same-length ambiguous
display names remain conservatively tagged because text alone cannot
disambiguate them.

…hive + P4a aggregation/D6 (block#4000)

## What

Implements Phases 2 and 4a of the Usage v2 plan (plan events
`d0268cd0`/`0e95b035`), extending the archive backend to emit,
transport, archive, and aggregate both cache categories and billing
identity fail-closed.

### P2 — emission, transport, archive

**Tri-state accumulators** (`Unseen`/`Exact`/`Unknown`) for cache-read
and cache-write in `buzz-agent` turn and session state. Absent field =
Unknown (never zero) through the full pipeline. No `unwrap_or(0)` on the
cache path. Both cache folds are gated on usage-bearing responses (same
gate as the total-state and identity folds) — a response with no usage
at all must not poison either accumulator.

**Overflow-aware input token parsing and accumulation** — closed
end-to-end from parse through wire to ACP:
- `sum_usage()` returns `SumUsageResult` (`Exact(u64)` | `Overflow`) —
checked arithmetic, never clamps. `anthropic_input_tokens()` returns
`Option<SumUsageResult>` since it sums three fields (`input_tokens +
cache_read_input_tokens + cache_creation_input_tokens`) that can
collectively overflow. Single-field callers (`prompt_tokens`,
`completion_tokens`, etc.) convert via `.into_exact()` — their
single-field sums cannot overflow.
- `LlmResponse.input_tokens_overflowed: bool` propagates the parse-layer
signal into the run loop. When set, `input_tokens` is `None` (clamped
value discarded), the context-gate baseline
(`last_request_input_tokens`) is frozen at its prior reading, and
`turn_input_tokens` is poisoned to `TurnIOState::Poisoned` before any
emission — including mid-turn `emit_usage_update` calls. A dedicated
enum on `LlmResponse.input_tokens` would ripple into ~20 existing test
assertions on `r.input_tokens == Some(...)`; the bool flag confines the
change to the two call sites that check it.
- `TurnIOState` (`Unseen`/`Exact`/`Poisoned`) for input and output:
per-round fold uses `checked_add`; overflow poisons permanently at turn
and session level, no healing. Absence does not poison (pass-2-cleared
contract unchanged). Wire emission omits
`accumulatedInputTokens`/`accumulatedOutputTokens` when poisoned — never
null, never `u64::MAX`. ACP treats absent = publisher-poisoned:
`delta_reliable: false`, null turn fields, null cumulative for that
category; session cumulative stays unknown for all subsequent turns once
poisoned.

**Conditional wire emission** for `accumulatedCachedInputTokens` and new
`accumulatedCacheWriteTokens`: fields are omitted when the cumulative is
Unseen or Unknown. ACP `_goose/unstable/session/update` contract
documented next to the payload with tests for all absence/zero variants.

**`PricingIdentity` stamping (publisher-side)**:
- `pricing_authority()`: canonical parsed-URL endpoint comparison
against the official allowlist — HTTPS only, exact allowlisted host
(lookalike-safe), default port (omitted or explicit :443), required API
base path, rejects userinfo/query/fragment/path-prefix lookalikes.
- Model: the actually-requested `request_model` after mesh/auto
resolution (not `effective_model_str`).
- Turn discipline: identity retained only while ALL usage in the current
turn carries one identical proven identity; any mismatch,
unproven-usage-bearing response, or unpaired cumulative snapshot poisons
to absent; a later matching notification does not heal a mixed turn.

**ACP `UsageTracker` identity fold**: per-in-flight-turn tri-state
identity accumulator replacing last-update-wins. Any absent identity on
a token-advancing notification or exact mismatch poisons to absent;
poison survives later updates; reset in `begin_turn()`/`take()`; reset
also when a request fails (baseline cleared so preflight gate cannot
stay frozen sub-threshold on retries).

**M3 migration**: adds `turn_cache_write_tokens`,
`cumulative_cache_write_tokens`, `pricing_authority`, `pricing_model`,
`pricing_cache_class` to `agent_metric_index`. Additive, idempotent,
guarded per-column by marker. M2 migration also guarded per-column (turn
and cumulative cache-read columns checked and added independently;
marker commits only after both are present). Fresh-DB schema includes
all columns.

**First-turn baselines**: `seed_zero_baseline` seeds `last_input:
Some(0)`, `last_output: Some(0)`, `last_cached_input: Some(0)`,
`last_cache_write: Some(0)`, and `last_total: Some(0)` — all have the
known-zero-at-spawn argument. Absent fields from incoming snapshots
still produce unknown (tri-state unchanged). Sessions buzz-acp did not
spawn (no seed) remain fail-closed on turn one.

**`ReportedUsage` TS mirror**: `cacheReadTokens`, `cacheWriteTokens`,
`freshInputTokens` added to `tauriArchive.ts` as `UsageField` members,
field-for-field with the Rust struct.

### P4a — aggregation layer

**Extended S-1 ladder** to cache-read and cache-write via the same
`ladder_token` path as the existing token fields.

**`freshInputTokens` derivation**: checked arithmetic, fail-closed —
absent cache fields produce Unknown (not zero), overflow and
`cacheRead+cacheWrite > input` both produce `incomplete: true`.
Aggregated as a `UsageField`.

**D6 comparator**: `sort_value()` = provider total when known, else
`input+output` when both known, else `None` (unknown-last). Replaces the
prior total-only comparator for both agent-level and model-level sort.
Ships a pinned test vector that the TS render layer (P5) must match.

## Test coverage

- `buzz-agent`: 440 lib + 15 integration (golden_transcripts) — includes
13 new `cache_total_state_tests`; 14 new `turn_io_state_tests`; 3 new
`sum_usage_*` tests (exact single-field, exact two-field, overflow
signals correctly); 3 new `parse_anthropic_*` tests (overflow flag set +
value cleared, normal sum no flag, absent usage no flag); end-to-end
golden transcript drives real subprocess with Anthropic-shaped
`input_tokens: u64::MAX, cache_read: 1` response and asserts
`accumulatedInputTokens` absent from the emitted `usage_update` — no
logic duplication; 3 wire pin tests; 4 `fold_pricing_identity_*` tests;
`pricing_authority()` explicit-:443 acceptance
- `buzz-acp`: 700 tests (691 lib + 9 integration) — 4 new usage tests
(absent input → unreliable+null; absent output → unreliable+null;
goose-shaped both present unchanged; poison mid-session); 3 ACP behavior
tests; 7 pool lifecycle tests
- Desktop (Rust): 2259+ tests — 14 new P4a pinned tests; 2 M3 round-trip
tests; 1 serde key-shape test; 2 M2 partial-schema migration tests;
first-turn cache round-trip test

## Summary

- deliver legacy ACP standing context once per live session, committing
delivery state only after a successful turn
- send only new thread/DM event deltas on later turns, with fail-open
behavior for missing IDs and failed/cancelled prompts
- fence native steer delivery acknowledgements by ACP session identity
so stale acks cannot poison replacement sessions
- keep context hints truthful when a fetch contains only the triggering
event versus history delivered earlier

## Validation

The pre-push hook passed on exact pushed head
`6a768f1bc80fe63c686acf8d730f177fff8add3c`:

- `branch-skew`
- `desktop-check`
- `desktop-typecheck`
- `desktop-test`
- `rust-tests`
- `desktop-tauri-checks`

Focused regression tests were also run while iterating:

- `channel_prompt_commits_delivery_state_only_after_acp_success`
- `in_flight_stale_native_steer_ack_cannot_update_replacement_session`
- thread/DM trigger-only versus previously-delivered context hint tests

## Known limitations and follow-ups

A local Goose smoke timed out at `session/new`. This diff does not
change code that executes at or before `session/new`; its earliest
affected runtime behavior is delivery-state insertion after session
creation succeeds. The smoke failure is therefore bounded as
environmental or pre-existing, but no successful live-provider turn was
obtained. Scripted ACP wire/lifecycle tests carry the regression
coverage.

- block#5421 — distinguish post-delta, already-delivered, and fetch-truncated
context counts
- block#5422 — define a standing-context re-delivery policy if a legacy
provider compacts it away

Durable process-restart/session resume remains out of scope for this
slice of block#5342. block#5386 also remains separate pending upstream adapter
support.

## Summary

- prioritize exact whole-lexeme matches within short kind-0 prefix
searches
- preserve the existing prefix result set, pagination, community/channel
scope, hydration, and authorization path
- add a Postgres regression where newer noisy `jm…` profiles saturate
the bounded page

## Why

Desktop mention autocomplete starts searching after one character. The
`jm` profile is indexed and matches both `jm:*` prefix search and
standard full-text search, but production prefix search returns a full
50-result page without it. Raw profile JSON supplies enough unrelated
`jm…` lexemes that newer equal-rank matches fill the bounded page before
the exact short display name.

Changing clients would leave deployed Desktop 0.5.8 installations
broken. This shared search-layer compatibility fix changes ordering only
for `Prefix + kinds:[0] + query length <= 2`; message search, longer
profile typeahead, and agent eligibility are untouched.

## Validation

At commit `ff88761135d5045139aeb3da14d08cbfba203169` with a clean
worktree:

- `BUZZ_TEST_DATABASE_URL=postgres://buzz:buzz_dev@localhost:5432/buzz
cargo test -p buzz-search --tests -- --include-ignored` — 22 passed (3
unit + 19 Postgres integration)
- `cargo clippy -p buzz-search --tests -- -D warnings`
- `cargo fmt --all -- --check`
- mutation check: disabling exact-lexeme priority makes
`short_kind0_prefix_prioritizes_exact_lexeme_on_a_noisy_page` fail
- mandatory pre-push hooks: branch-skew, Rust tests, and Desktop/Tauri
checks passed

## Risk

Low. The extra ordering predicate applies only to one- or two-character
prefix searches restricted exactly to kind 0. It does not add
candidates, bypass filters, or alter access control. Exact matches move
ahead of broader prefix matches; all remaining ordering stays relevance,
recency, then event ID.

## Summary

Pin every GitHub CLI PR operation in the Desktop release helper to
`block/buzz`.

Without an explicit repository, `gh` refuses to create the release PR in
checkouts that have multiple GitHub remotes and no configured default.
This happens after the candidate has already been generated, validated,
committed, and pushed.

Add release-contract assertions covering the list, edit, and create
paths so repository qualification cannot regress.

## Validation

## Summary

Separate OSS desktop artifact publication from fleet-wide auto-update
promotion.

- retain the exact generated updater manifest as `updater-manifest.json`
on each immutable `desktop-vX.Y.Z` release
- stop the tag-triggered build from mutating
`buzz-desktop-latest/latest.json`
- add a `main`-only manual promotion workflow with one global
concurrency group
- validate stable semver, release/tag commit identity, draft/prerelease
state, exact platform set, signatures, version-bound asset URLs, asset
existence, monotonicity, idempotent retries, and a final stale-state
check before writing
- document the operator flow and pin the split with focused contract
tests

## Safety behavior

Publishing a versioned GitHub release no longer exposes it through the
in-app updater. Operators can install and test those exact
signed/notarized artifacts, then manually run **Promote OSS Desktop
Auto-Update** with the stable version.

Promotion rejects downgrades. A same-version retry succeeds only when
the rolling and candidate manifests are byte-identical. The workflow
re-reads the current rolling version immediately before its only write
and records the actor, source tag commit, previous version, manifest
digest, and run URL.

## Verification

Verified at commit `39caf1603be06bb476905225ec55f7bbbe86b237`:

```text
scripts/test-oss-desktop-promotion.sh
OSS desktop promotion contract passed

scripts/test-release-ref-contract.sh
release ref contract passed

git diff --check origin/main...HEAD
(clean)
```

The repository pre-push hook also passed `branch-skew` for the exact
pushed head; package suites were correctly skipped because this change
only touches release workflows, scripts, and documentation.

…5453)

Part of block#5418 (Phase 1, lane B).

## What

Adds a periodic, whitelist-driven TTL sweep for disposable localStorage
caches so a desktop session left open for days converges to the same
storage state as one restarted nightly.

- New `desktop/src/shared/lib/localStorageSweep.ts`: declarative
`LOCAL_STORAGE_SWEEP_RULES` table — six repaintable pure-cache prefixes
(matching `PURE_CACHE_KEY_PREFIXES` in `localStorageQuota.ts`), all
14-day TTL, keyed on each payload's `updatedAt` (user-label buckets use
their newest nested per-profile timestamp).
- Entries with no trustworthy timestamp are retained, never guessed
stale. `buzz-self-profile.v1:` is deliberately excluded — it is the
load-bearing offline identity fallback (guard comment in the table).
- Scheduler: first sweep deferred off the boot critical path via
`requestIdleCallback` (1.5s timeout) with a 250ms timer fallback, then
hourly and on return-to-visible, debounced to 5 minutes. Throw-safe
throughout (failures `console.warn`, never crash — per `safeStorage.ts`
conventions / block#5078).
- Wired in `desktop/src/main.tsx` beside
`recoverLocalStorageQuotaOnStartup()`.

## Validation

- Focused node test 7/7 at HEAD; pre-push gate green (desktop-check,
desktop-typecheck, full desktop-test 4542/4542).
- Manual Playwright (not covered by push hooks):
`relay-connectivity.spec.ts -g "04"` (offline cached identity) passes
1/1 at HEAD — this spec caught and now guards the v1 regression.
- Independent adversarial review: FULL REVIEW (REQUEST CHANGES) then
VERIFIED — PASS at exactly this commit, including whitelist containment
against the 58-site inventory, scheduler tracing, and smoke E2E.

Part of block#5418 (Phase 1, lane A). Companion to block#5453 (TTL sweep).

## What

Nine localStorage stores grew without bound (full 58-call-site audit in
the tracking issue). Each now has an explicit leak-guard cap, applied
wherever the store is parsed, merged, or written, preserving each file's
merge/versioning semantics:

- **Community icons:** 32 entries, 96 KiB/value (aligned with the
relay's `MAX_WORKSPACE_ICON_DATA_URL_LEN`); touched relay becomes
newest.
- **Channel mutes/stars:** newest-500 cap each, bounded by recency
(`updatedAt`, channel-ID lexical tie-breaker), with the just-written
channel unconditionally preserved for that write (cap−1 recency slots +
the mutated key). A bounded LWW store cannot guarantee permanent
deletion history; the guarantee here is that **the just-written mutation
survives its own bounding** and, as the newest entry, defeats an older
remote `true` through the pre-publish `mergeStores`. Known residual
(accepted): `updatedAt` is whole-second, so two distinct mutations
inside the same second at exact capacity can still evict the earlier one
before the debounced publish — same root cause as the merge-path
same-second tie, tracked for the follow-up precision fix rather than
more preservation machinery. Enforced at parse, post-merge, local state,
and persistence.
- **Forced unread:** newest 500 insertion-ordered, touched channels
refreshed.
- **Persistent agent audiences:** 200-scope LRU. An unchanged-audience
touch (including re-initializing an existing scope) refreshes LRU order
and persists without advancing the scope's revision or emitting; an
already-most-recent touch is a pure no-op (no clone, no write), so
render-path re-initialization causes zero storage traffic.
- **Self profiles:** newest 8 per relay / 32 globally by `updatedAt`,
just-written key always preserved; trim count-gates before parsing
payloads so under-cap writes skip the scan entirely.
- **Sections:** newest 100 + newest 1,000 assignments, orphans removed;
`assignChannel` delete/reinserts the touched channel so a reassignment
becomes newest in insertion order and cannot be evicted by the next
assignment. **Sort prefs:** 104 groups (100 sections + 4 fixed).
- **Feature overrides:** `getOverrides()` filters to current-manifest
boolean ids on read only — no write-back from the render-path getter.

## Review-driven revisions

- `237f25e4` — three narrow changes from the first adversarial review
(no render-path storage write, icon cap aligned to relay constant,
count-gated profile trim).
- `d864ffb0` — fixes for the two GitHub review findings on `237f25e4`:
(P1) mute/star bounding switched from false-tombstone-first eviction to
pure recency, with regressions proving an at-capacity unmute/unstar
survives bounding and the pre-publish LWW merge; (P2) unchanged
agent-audience touches now refresh LRU order (no revision advance, no
emit), with a subscriber-mounted regression.
- `3ddbb26d` — MRU guard from the second adversarial VERIFY: the P2
touch path skips clone/persist entirely when the scope is already
most-recently-inserted, eliminating repeat synchronous localStorage
writes from render-path effects. Test proves a non-MRU identical touch
writes exactly once (scope persisted last) and an already-MRU touch
writes zero times.
- `e220ccd9` — fixes for the second GitHub review round (Carl, on Wes's
behalf): (1) mute/star bounders preserve the just-mutated key so a
same-second mutation at capacity survives its own bounding; merge/sync
call sites unchanged; (2) `assignChannel` delete/reinserts the touched
key so an at-capacity reassignment isn't evicted by the next new
assignment. Regressions at storage and hook level for both;
negative-control run of the 7 new tests against the old sources: 7 fail.

## Validation

- Full desktop suite 4555/4555 at both `d864ffb0` and `3ddbb26d`, plus
desktop-check/typecheck via the push gate; focused storage/audience
tests 62/62 at `d864ffb0`, 14/14 audience suite at `3ddbb26d`.
- Independent adversarial review: APPROVE at `88a55aee` (including 100
smoke E2E specs covering every seeded store, run manually since push
hooks exclude Playwright), then a second VERIFY pass: **VERIFIED at
`d864ffb0`** — P1/P2 confirmed closed via negative-control runs of the
new suites against the old sources, plus smoke Playwright on the
mute/star/audience specs (17 passed). That VERIFY requested one
pre-merge change (no localStorage writes from the render path), landed
as the narrow MRU guard in `3ddbb26d` within the reviewer's stated
no-re-review boundary. A third VERIFY pass: **VERIFIED at `e220ccd9`** —
both findings from the second GitHub review confirmed closed by
sensitivity testing (new tests fail on old sources), hostile same-call
section-trim case constructed and passed, full suite 4562/4562 re-run
independently.

## Summary

- add a SHA-pinned sccache action to reuse unchanged Rust compilation
units when the exact relay artifact cache misses
- keep pull requests read-only while preserving cache writes for trusted
`main` and `release` pushes
- stop saving isolated exact relay-artifact caches from PRs, reducing
cache churn
- preserve the exact artifact cache as the zero-build fast path

## Why this is an experiment

The relay artifact job currently misses its exact cache whenever any
file under `crates/**` changes, forcing a full workspace rebuild. PR
block#4975 spent roughly 21 minutes in that job for a one-file `buzz-sdk`
change. sccache targets the relevant reuse boundary—individual compiler
inputs—but the repository cache pool is already under heavy eviction
pressure, so this PR does **not** claim a proven timing win yet.

## Safety

- `Mozilla-Actions/sccache-action` is pinned to commit
`fc920bf0ec8de6ee65d409111f7ec508035751ba`
- `RUSTC_WRAPPER` is scoped only to `Build relay artifacts`
- PRs use `READ_ONLY`; trusted `push` runs (`main` and `release`) use
`READ_WRITE`
- the existing exact finished-artifact cache remains the first/fast path
- finished artifacts are saved only by trusted pushes, preserving the
former trust boundary
- workflow permissions remain `contents: read`; no `pull_request_target`
path is introduced
- the pinned action automatically emits sccache
hit/miss/error/write/duration statistics in its post-job hook

## Validation

- `actionlint .github/workflows/ci.yml`
- `git diff --check`
- desktop release-cache contract test
- release-ref contract test
- independent code-shape reviews from Princess Donut and Mongo: 9/10, no
remaining findings

## Measurement plan

1. purge obsolete PR-scoped `relay-artifacts-*` cache entries before
measurement
2. merge/push a trusted writer to populate sccache
3. run a representative one-crate PR
4. compare relay job duration and automatic sccache statistics against
the 21–22 minute baseline
5. retain this only if the warm run demonstrates material improvement

## Summary

- restore private-channel invitations for every active member
- keep owner/admin-only enforcement for elevated role grants, active
role changes, and removals
- preserve block#4612's unrelated Desktop/mobile failure handling and
hardening
- add relay coverage for the ordinary actor/target role matrix

…ck#5490)

Fixes block#3677.

## Problem

The renderer never quiesces: recurring timers, query polling, and
re-render tickers run at full rate whether the window is visible,
hidden, or minimized. Measured on a live installed app: **27.5% mean
renderer CPU visible vs 28.7% hidden** (60×1s `ps` samples of the
WebContent process; `sample(1)` dominated by
`WebCore::timerFired`/ThreadTimers, microtask checkpoints, JSON parsing,
style matching). Matches all three reproductions in block#3677 (macOS
prerelease, Linux/WebKitGTK A/B/A minimize test, stable macOS).

Per-timer instrumentation (dev build, wrapped
`setInterval`/`setTimeout`/rAF) attributed the recurring work: `useNow`
60 fires/min, 40 active TanStack refetch intervals, agent-turn pruning
12/min, auto-restart ticks, huddle/reminder polls — none
visibility-gated.

## Fix (two-tier gating, standard mechanisms only)

Two separate signals in `desktop/src/shared/lib/useDocumentVisible.ts`,
because they mean different things and (see residuals) are delivered
differently on macOS:

- **`useDocumentVisible`** — true Page Visibility only
(`document.visibilityState`). Gates local UI work that must keep running
on a visible-but-unfocused window: `useNow` relative clocks, agent-turn
pruning, huddle bar state/model-status polling, auto-restart tick.
Hidden ⇒ paused; `useNow` snaps to fresh `Date.now()` on return.
- **`useAppFocused`** — visible AND `document.hasFocus()`. Gates network
refetch polling only (`useFocusedRefetchInterval`, ~15 query families:
forum/home/agents/channels/templates/emoji/user-status/projects/workflows/persona-catalog/pulse/presence-list).
TanStack's `focusManager` is wired to this signal (idempotent, single
install) with `refetchOnWindowFocus: true`, so stale queries refresh
promptly on return. Deliberate side effect, documented in code: query
retries pause on blur; mutations and the presence heartbeat (`retry: 0`)
are unaffected.
- **Never gated:** reminder due-notification poll (fires while
hidden/unfocused — extracted to `reminderNotificationPoll.ts` with
regression test), huddle pipeline hot-start (`check_pipeline_hotstart`
survives backgrounding for the duration of a huddle), relay stall
watchdog, presence heartbeat. Live WebSocket delivery untouched
throughout.
- Huddle model-status indicator now clears only on huddle phase end, not
on visibility/focus changes.

## Validation

- Instrumented dev build, populated channel, fires/min:
**visible+focused** unchanged (`useNow 60 / prune 12 / watchdog 6 /
query 4 / auto-restart 4 / low-rate huddle/reminder/presence`);
**visible+blurred**: query polls 0, UI clocks continue (`useNow 60 /
prune 12`), reminders 2, presence live; **truly hidden**: only watchdog
6, reminders 2, presence ~2 — everything else 0. Return restored
visible+focused, selection preserved, queries refreshed.
- Hide-vs-blur decomposition (instrumented probe instance,
AppleScript-driven): on macOS WKWebView, Cmd-H / minimize / full
occlusion did **not** reliably produce `visibilityState === "hidden"` —
they reliably produced focus loss. The CPU-dominant quiescence path on
macOS is therefore the focus gate; the visibility gate is exercised
fully on platforms that report hidden (e.g. WebKitGTK minimize per the
Linux repro).
- Gate-regression tests: signal separation, `useNow` hidden-pause +
fresh-snap on return, focus-gated interval pause/resume-with-refresh,
reminder delivery while hidden+unfocused (5 new, plus primitive wiring
tests).
- Push gate: desktop check, typecheck, full desktop suite **4549/4549**
at `1237548d1`.

## Known residuals

- **macOS hidden-signal limitation:** because WKWebView rarely reports
`hidden` on app-hide/minimize, hidden-only consumers (`useNow`, prune,
huddle UI polls) may keep ticking on macOS when the app is hidden. These
are cheap local timers; the expensive network polling still quiesces via
focus loss, which is what the measured 28% CPU was attributed to. If the
residual local-timer cost proves measurable, the follow-up is bridging
Tauri window hidden/minimized events into the visibility signal.
- End-to-end CPU confirmation on a packaged build is the post-merge
follow-up (against the 28% idle baseline).
- Visible-state costs (skeleton animation pileups on stuck loading
views, per-poll JSON payload churn) are intentionally out of scope —
separate follow-up issue.

## Why
`buzz channels update` could already change name, description, and TTL,
but the SDK/relay/DB path for channel visibility was unreachable from
the CLI.

## What
- Add `--visibility open|private` to `buzz channels update`
- Pass the visibility value through to `build_update_channel`
- Add guard tests proving empty updates still fail and visibility-only
updates are accepted

## Risk Assessment
Low — this is limited to the buzz-cli update command and uses existing
SDK validation plus existing relay/DB handling.

**Category:** fix
**User Impact:** Buzz pull request, issue, and repository links now show
compact, useful metadata cards in received messages, including messages
sent by agents and the CLI.

**Problem:** Sender-authored snapshots protect recipients from external
preview fetches, but that change also removed recipient-side cards for
trusted Buzz entity links when the sender did not attach snapshots.

**Solution:** Resolve recognized Buzz entities only against the active
relay and show signed repository identity, title, and compact builder
context with the current inline Buzz mark in the favicon slot, but
without avatars, thumbnails, or external image fetches. Entity metadata
wins over conflicting sender snapshots, while unsupported or unavailable
metadata retains a safe text fallback.

<details>
<summary>File changes</summary>

**desktop/playwright.config.ts**
Adds the entity-link regression spec to the smoke test project.

**desktop/src/features/messages/ui/useComposerLinkPreviews.tsx**
Treats recognized Buzz entity cards as complete without generating
snapshot tags and retains fallback cards when relay metadata is absent.

**desktop/src/shared/lib/useResolvedLinkPreviews.test.mjs**
Covers kind-scoped entity detection, trusted relay metadata, root-scoped
lifecycle queries, exact single-repository root binding, image-less
pending state, and fallback behavior.

**desktop/src/shared/lib/useResolvedLinkPreviews.ts**
Resolves signed repository, pull request, and issue metadata from the
active relay. Entity roots fail closed unless they carry exactly one
matching repository tag; lifecycle queries are root-scoped before
limits; successful metadata remains stable until relay/community reset,
and PR commit context uses the immutable root event rather than an
unindexed update query.

**desktop/src/shared/ui/compact-link-preview-attachment.tsx**
Uses Buzz repository identity as the compact card provider and avoids
reserving thumbnail space for image-less entity cards.

**desktop/src/shared/ui/markdown.tsx**
Routes message cards through the combined entity/snapshot preview hook.

**desktop/src/shared/ui/markdown/useMessageLinkPreviews.test.mjs**
Proves relay-authenticated entity metadata beats a forged sender
snapshot while preserving mixed-link content order.

**desktop/src/shared/ui/markdown/useMessageLinkPreviews.ts**
Combines recipient-resolved Buzz entities with sender-authored external
snapshots using explicit trust precedence and first-seen ordering.

**desktop/tests/e2e/entity-link-recipient-cards.spec.ts**
Exercises repository identity, PR workflow context, repository metadata,
image-less rendering, and composer send behavior for agent/CLI-style
entity links.

</details>

## Reproduction steps

1. Open a channel containing a message sent without `link-preview` tags
whose content includes valid `buzz://pr`, `buzz://issue`, or
`buzz://repo` links.
2. Confirm each card shows its repository identity and signed title;
PRs/issues also show compact lifecycle context, and repositories show
description/status/default branch.
3. Confirm the cards use the Buzz mark in the favicon slot with no
avatar, thumbnail, or reserved image area.
4. Compose and send a message containing a Buzz entity link; confirm
sending is not blocked waiting for a snapshot.
5. Send a message containing both a Buzz entity link and a
snapshot-backed HTTPS link; confirm cards follow content order and the
HTTPS link remains sender-snapshot-only.

## Screenshots

### Recipient view — Buzz-branded metadata cards

Repository identity, title, and compact builder context render with the

…olve (block#5245)

## Overview

**Category:** fix  
**User impact:** Link previews no longer disappear when a message is
sent while preview metadata or media is still settling. Fast Enter,
rapid Enter, and confirmed-draft auto-send now preserve the preview
without duplicate sends or stale tags.

**Problem:** The composer could look ready before its sender-authored
snapshot tag existed. Send paths could then race preview
resolution/upload, while debounced preview state could attach a tag for
a URL that had already been removed. The same timing also caused
confirmed-draft auto-send to be consumed without sending.

**Solution:**
- Debounce preview resolution to avoid card flicker while typing, then
disable every submit path while a supported external preview settles. A
2-second escape cap still permits a bare-link send if resolution stalls.
- Keep submit synchronous: acquire a composer-local lock before
asynchronous send work, read ready tags from the live URL set, and
reject Enter/form submits while a snapshot is pending.
- Retry confirmed-draft auto-submit until preview settling clears, then
submit exactly once.
- Upload thumbnail and favicon independently. A failed upload shows a
toast and degrades to the surviving media (or text-only) rather than
leaving the card spinning.
- Exclude message-edit mode from preview resolution, upload, and Save
gating. Edit-time preview snapshots remain follow-up block#5273.
- Canonicalize fragment-bearing URLs for preview lookup/snapshot
identity while preserving the original fragment links in message text.

## Link preview state walkthrough

Captured using PR block#5245's actual public Open Graph metadata and artwork.
The deterministic E2E bridge controls only upload timing so the
transient disabled state can be captured reliably.

| State | Expected behavior | Screenshot |
| --- | --- | --- |
| **1. Snapshot upload pending** | The real PR preview is visible, but
Submit remains disabled until its sendable snapshot tag is ready. Click
and Enter cannot send a bare link during the settling window. | ![PR
5245 pasted with its real preview visible and Submit
disabled](https://d24qwcpro867f5.cloudfront.net/repos/buzz/prs/5245/01-real-pasted-submit-disabled.png)
|
| **2. Snapshot ready** | Once snapshot upload settles and the tag is
ready, the same preview remains and Submit becomes active. | ![PR 5245
preview ready in the composer with Submit
enabled](https://d24qwcpro867f5.cloudfront.net/repos/buzz/prs/5245/02-real-resolved-submit-enabled.png)
|
| **3. Message sent** | The sent event carries the snapshot tag and
renders the PR title, description, and artwork inline instead of
degrading to a bare URL. | ![PR 5245 real link preview rendered inline
in the message
list](https://d24qwcpro867f5.cloudfront.net/repos/buzz/prs/5245/03-real-sent-preview-inline.png)
|

## Regression coverage

- Enter during metadata resolution or snapshot upload cannot send early.
- Paste-and-immediate-Enter sends after settling; rapid Enter submits
exactly once.
- Confirmed-draft auto-send waits for settling and fires exactly once.
- Removed/replaced URLs cannot leak stale snapshot tags or media refs.
- Thumbnail upload failure toasts and sends with the surviving favicon.
- Edit mode does not resolve/upload previews or gate Save.
- Fragment variants share a canonical preview while original fragment
links remain clickable.
- Existing ready-preview, suppression, bare-link fallback, and
multi-preview behavior remains covered.

## Reproduction steps

1. Open a channel and paste a supported external URL into the composer.
2. Press Enter immediately, before preview metadata/media finishes
settling.
3. Before this fix, the event could be sent without its preview snapshot
(or confirmed-draft auto-send could be lost). With this fix, submit
waits behind the disabled state and fires once with the matching
snapshot tag.
4. Remove or replace the URL and press Enter inside the debounce window.
The sent event contains tags only for URLs still present in the
submitted content.

…ock#5534)

Hardens the Databricks PKCE OAuth code in
`crates/buzz-agent/src/auth.rs`. Two fixes.

## Token cache is owner-only across its whole lifecycle, and race-safe

The PKCE cache holds both the access and refresh tokens, but `save()`
wrote it with a bare `fs::write` + `fs::rename`. Under a `022` umask the
file landed world-readable, and the fixed `*.json.tmp` temp name races
across concurrent savers sharing `$HOME` — one writer's `rename` can
fail on another's half-written temp.

**On write**, `write_private_cache()` creates a temp file with
owner-only permissions from the moment it exists — mode `0o600` on Unix
via `OpenOptions::mode` — writes and fsyncs it, then renames over the
destination. The rename swaps the inode wholesale, so a pre-existing
cache file with loose permissions is *replaced* by the new private inode
rather than inheriting its mode. `unique_suffix()` (getrandom, timestamp
fallback) gives each write a distinct temp name, and a drop guard
removes the temp on any failure path.

**On load**, owner-only is enforced as a cache lifecycle invariant, not
just a write-path property. A world-readable cache left by an older
buzz-agent was previously read straight into memory and returned on the
fresh cache-hit path without ever invoking `save()`, so a token file
with no advertised expiry could stay exposed indefinitely.
`read_cache()` now funnels every load — initial and cross-process
re-reads — through `read_private_cache()`, which on Unix opens with
`O_NOFOLLOW` (kernel-level symlink refusal, no stat/open TOCTOU),
requires a regular file, and `fchmod`s the pinned handle to `0o600` when
any group/other bit is set. A cache that cannot be secured is treated as
absent, so callers fail closed to a fresh flow rather than trusting an
exposed file.

## OAuth callback no longer reflects untrusted input

The localhost callback embedded the untrusted `error` query param
straight into the HTML response — an XSS sink on the redirect page — and
routed that same raw value into the error string that reaches the logs.

`callback_outcome()` is now a pure function returning `(result,
static_page)`: the browser always sees a fixed literal page that embeds
no request parameter, and failure detail travels only through the result
channel. `sanitize_callback_detail()` strips control characters (CR/LF
log-line injection) and caps length before that detail enters the error
string bound for the logs.

## Deferred: Windows owner-only ACLs

Windows owner-only protection is out of scope for this change. The
goose-parity route (`CreateFileW` with an owner-only SDDL
`D:P(A;;FA;;;OW)`) requires `unsafe` FFI, which this crate's
`#![forbid(unsafe_code)]` prohibits; reconciling that conflict is a
separate decision. Both platform seams — `create_private_temp_file`
(write) and `read_private_cache` (load) — have a `#[cfg(not(unix))]`
branch that relies on the default per-user ACLs and is the drop-in point
if Windows protection is added later. No new dependency and no `unsafe`
are introduced here.

**User Impact:** YouTube video links now resolve into reliable previews
instead of intermittently appearing as bare links.

**Problem:** Buzz intentionally reads at most **256 KiB** of page HTML
when building a generic link preview. The YouTube response that exposed
this bug was roughly **1.3 MiB**, with its Open Graph metadata beginning
around **686 KiB**—well beyond Buzz's bounded read—so extraction
returned no usable preview. YouTube can move that metadata between
responses, which explains why the same link may appear to work in one
build or request and fail in another; raising the generic cap would
increase bandwidth and allocation for every site while still scraping an
unstable application document.

**Solution:** Route recognized YouTube video URLs through YouTube's
structured oEmbed endpoint instead of parsing raw watch-page HTML. The
provider response is capped at **64 KiB** and retains Buzz's existing
HTTPS validation, pinned DNS/SSRF protection, disabled redirects,
timeouts, metadata bounds, and thumbnail sanitization. Provider failures
return no preview rather than falling back to fragile HTML scraping, and
embed URLs are canonicalized safely, including percent-encoded video
IDs.

<details>
<summary>File changes</summary>

**desktop/src-tauri/src/commands/link_preview.rs**
Recognizes supported YouTube URL forms, fetches bounded JSON metadata
from YouTube oEmbed, canonicalizes embed links, and adds response,
URL-boundary, malformed-data, resource-limit, and encoded-ID
regressions.

**desktop/src-tauri/Cargo.toml**
Declares percent decoding as a direct desktop dependency for safe
embed-ID canonicalization.

**desktop/src-tauri/Cargo.lock**
Records the direct dependency in the desktop package lock entry.

</details>

## Reproduction Steps

1. On the base branch, paste a YouTube URL whose Open Graph metadata
falls beyond the first 256 KiB of the raw watch-page response and
observe that no preview is produced.
2. Run this branch and paste a YouTube watch, mobile, music, `youtu.be`,
Shorts, live, or embed URL into the composer.
3. Confirm the preview resolves with the video's title, creator, and
sanitized thumbnail without downloading the full watch-page HTML.
4. Try an embed URL with a percent-encoded ID, such as
`https://www.youtube.com/embed/%64Qw4w9WgXcQ`, and confirm it resolves
to the same video.
5. Try a YouTube lookalike domain or an embed ID containing encoded
separators and confirm it is not routed through the provider path.

**User Impact:** Previously selected community themes are preserved when
opening a relay through onboarding, while first-time theme migration
still completes for communities with no saved theme.

**Problem:** During community initialization, desktop queried theme
history before establishing live delivery. If a replacement event
arrived while an empty history query was in flight, the client could
incorrectly treat the theme as absent and publish the default over the
user's saved selection.

**Solution:** Subscribe before fetching history, expose whether live
readiness reached EOSE, flush buffered live events before resolving
EOSE, and retain the newest delivered replacement through hydration.
Seed the inherited/default theme only when both live and history
snapshots reach EOSE with no valid or unreadable event; subscription
failures, CLOSED, readiness timeout, relay failure, and unreadable
events fail closed without publishing.

<details>
<summary>File changes</summary>

**desktop/src/shared/api/relayClientSession.ts / relayClientShared.ts /
relayClosedRecovery.ts**
Distinguish EOSE from CLOSED/timeout readiness and flush buffered events
before resolving an EOSE fence.

**desktop/src/shared/theme/CommunityThemeController.tsx**
Seed and complete first-community migration only for confirmed absence;
uncertain hydration remains non-publishing.

**desktop/src/shared/theme/communityThemePreference.ts**
Keep the inherited appearance for the first migrated community and the
stable default for later empty communities.

**desktop/src/shared/theme/communityThemeSync.ts**
Arbitrate live and history results into valid, confirmed-absent,
invalid, or unavailable hydration outcomes.

**Tests**
Cover EOSE/CLOSED readiness, subscription failure, timeout, unreadable
and live-racing events, no-op initialization, and first-to-later
community fallback isolation.

</details>

## Reproduction steps

1. Save a non-default appearance for a community relay.
2. Remove the community locally, then open the same relay again through
onboarding.
3. Arrange for the saved replacement event to arrive live while the
initial history query returns empty.
4. Confirm the saved appearance remains selected and the client does not
publish the default theme over it.
5. On an account with no theme records, open a first empty community and
confirm its inherited appearance is migrated; open a later empty
community and confirm it starts from the stable default.

- **MeshLLM v0.74.0 → v0.75.1.** v0.75.0 added
`degrade_to_single_model`, so a
  `model=mesh` request is answered by one served model when there is no
committee to form, instead of failing. v0.75.1 adds Mesh-LLM#1196, which
skips stale pre-0.75 runtime cache entries rather than aborting startup
on
them — without it, anyone who had run mesh on 0.73/0.74 could not start.
- **Deleted the client-side mesh catalog probe.** buzz-agent used to
poll
`/v1/models` (5s TTL, 30s cooldown, two-observation debounce) to decide
whether `mesh` was safe to send. MeshLLM now decides per request, so the
  polling, its hysteresis, and its 503 fallback are gone.
- **One mapping point.** `relay_mesh_wire_model()` turns the stored
value into
a wire name: `auto` becomes `mesh`, a named model passes through. The
spawn
env, the ACP harness, and the readiness probe all use it, so they cannot
disagree — previously `BUZZ_ACP_MODEL` and the probe both said `auto`, a
name
  the mesh does not advertise.
- **Removed the `nostr-relay-pool` advisory exception.** block#5404 allowed
RUSTSEC-2026-0243 "after mesh-llm migrates to nostr-sdk >= 0.45".
v0.75.1
does, so the retired crate is gone from both lockfiles and the exception
  would only mask a future advisory for it.
- **Deleted `scripts/ensure-mesh-native-runtime.sh`** and its six
justfile call
sites. It built llama.cpp from source into the runtime cache; the app
already
  downloads the signed release runtime itself, and CI never called it.

## Why it is better

**−639 lines of Rust.** Availability is decided by the node that knows
the
answer, per request, instead of by a client cache that could be stale
for up to
30 seconds. A second worker joining now takes effect on the next request
rather
than after two confirming probes.

## Behaviour change

A 503 on an explicit `mesh` request takes the ordinary transport retry
under
the same model instead of failing over to a second one — there is no
second
model to fail over to now. MoA repairs partial committee results
internally
before it reaches that point.

## Validation

`crates/buzz-relay/examples/mesh_agent_e2e.rs` now sends `mesh` where it
previously sent `auto` or the physical model id, so no leg was covering
what
Buzz actually puts on the wire. 4/4 on gemma-4-E4B, gemma-4-26B-A4B, and
Qwen3-8B — including a real ACP tool call through `mesh` into
buzz-dev-mcp,
asserted by reading the written file back off disk.

Hand-tested in the desktop app on both gemma-4 sizes: picked Auto, agent
logged
`model_id=mesh`, replied in channel.

## Not covered

A committee that forms and then loses a worker returns 502, and that
needs two
workers to reproduce — not testable on one machine.

…home-feed (block#5535)

Fixes the 0.5.9 sluggishness Wes reported in app-slowness-mac (channel
list slow, content slow).

## Problem

block#5490 (shipped in 0.5.9) flipped ~20 query sites to
`refetchOnWindowFocus: true` and wired TanStack focusManager to app
focus. Instrumented at that exact commit: regaining focus after >60s
away fires **7 query fetches within 2ms**, including `get_channels`,
which settles at **~3.6s** (production probe: median 3.2s at 1,133
channels — 8 serial round-trips, 1,133-filter last-message batch). In
0.5.8 this burst was zero by configuration. Net: a burst of fetch/parse
contention exactly when the user returns to the app.

Relay ruled out: v0.2.1 small reads are 2–4ms upstream; nothing in
v0.2.0..v0.2.1 degrades the query path. The O(N) `get_channels` design
is a pre-existing issue (June analysis) — this PR fixes the new stampede
that made it user-visible.

## Fix

Raise `staleTime` to 5 minutes on the two expensive focus-refetch
families — `channels` and `home-feed` — so a focus return inside that
window serves cache instead of refetching. `refetchOnWindowFocus: true`
only refetches stale queries, so genuinely old data still refreshes on
return.

Unchanged: focused polling cadence (60s channels / 30s home-feed;
interval refetches ignore staleTime), block#5490 blur quiescence (no changes
to `useDocumentVisible.ts`/`queryClient.ts`), all push-style
invalidation paths (`invalidateQueries` bypasses staleTime), and
channels cold-start revalidate (`initialDataUpdatedAt: 0`).

## Validation

- New regression test
`desktop/src/features/home/focusRefetchPolicy.test.mjs` (4/4): fresh
focus return → 0 fetches; stale → 1; polling constants locked.
- Pre-push gate at the reviewed tree: desktop-check, desktop-typecheck,
full desktop-test **4588/4588**.
- Independent adversarial review (Beth): APPROVE at tree `4e2546ec` —
verified fresh-skip/stale-refetch against query-core 5.100.14 source,
polling-cadence via browser-simulated probe, side-effect sweep of all
invalidation paths clean. Sole CHANGE was commit trailers, fixed by
amend (tree unchanged).

## Known residual

Focus returns after >5min still fire the full burst including the
~3.2–3.6s `get_channels`. This cuts stampede frequency, not magnitude —
the O(N) `get_channels` relay path (RESEARCH/GET_CHANNELS_SLOWNESS.md)
is the follow-up that fixes magnitude.

## Summary

- skip the channel subscription catch-up request when the authoritative
channel window was fetched successfully within the existing five-minute
freshness period
- keep the responsive deferred skeleton for populated channel switches
instead of briefly rendering empty-channel actions
- preserve a real empty-channel intro across the first appended message
only after React has committed that empty state

This is intentionally narrow. It does not claim to solve the separate
sidebar startup cost or general main-thread stalls found during the
investigation.

### Related issue

N/A — no matching open issue or PR found.

### Testing

- pre-push desktop gate on `f1be6beea90b9715e04e5fc65cc5cfbe8210e0d9`:
  - desktop tests: 4,621 passed
  - desktop check: passed
  - desktop typecheck: passed
  - branch-skew: passed
- focused cache/surface/lifecycle tests: 62 passed
- manual diagnostic trace after rollback:
  - 16/16 channel revisits skipped catch-up refresh
  - 0 revisit refresh starts
  - 0 populated-channel empty/intro flashes
  - cached switches retained the deferred skeleton-to-list path

No screenshot: the regression is a transient channel-switch state and
request behavior, covered by lifecycle tests and the diagnostic trace
rather than a stable visual diff.

…lock#5569)

## Problem

Canceling the native macOS file chooser leaves the composer's temporary,
detached `<input type="file">` without a `change` event or an explicit
cleanup path. Opening Finder again immediately creates a second detached
input while WebKit may still be unwinding the first picker. The newly
selected files can therefore fail to reach the upload pipeline. Drag and
drop is unaffected because it bypasses this picker lifecycle.

This does **not** add an automatic retry mechanism. “Retry” means the
user's next attachment attempt after canceling or after a prior
selection.

## Fix

- give each composer hook one hidden, body-mounted file input for its
lifetime instead of creating a detached one per click
- reset and reconfigure that input before every open, replace its
handler rather than stacking handlers, and remove it cleanly on unmount
- preserve normal selection, cancel then reopen, selecting the same file
again, and multi-select behavior
- accept canonical `text/html` attachments while continuing to serve and
render them strictly as inert downloads
- keep XHTML, SVG, JavaScript, and executable MIME types blocked

The picker change fixes the ownership/lifecycle bug at its source; it
does not retry failed uploads, add delays, or mask errors.

## Testing

- mandatory pre-push gate: branch-skew, desktop typecheck/tests/check,
Rust tests, and desktop Tauri checks passed on
`ea5a97adf957803935b28d63d32f9f332cf65287`
- `cargo test -p buzz-media --lib` (110 passed)
- `pnpm --dir desktop typecheck`
- focused Biome check for the three picker files
- picker Playwright regression: cancel/no selection then reopen, select
the same file again, and multiple selection (run on the source commit
before integration)
- HTML live-relay response regression added as ignored E2E because it
requires the S3-backed relay harness

## Manual verification

Playwright models cancellation with Chromium's
`FileChooser.setFiles([])`; it cannot exercise the native macOS Finder
panel/WebKit presentation lifecycle. Before merge, manually verify in
the built macOS app:

1. select a PNG normally
2. cancel, then immediately reopen and select a PNG
3. select the same PNG on a subsequent attempt
4. multi-select two PNGs

## Why
Expose PostgreSQL datastore latency within existing request traces so
slow logical database operations can be identified without recording
tenant data or query arguments.

## What
- Add client spans around logical PostgreSQL operations across the
database facade, search, audit, replica fencing, and command persistence
- Use a dedicated `buzz_datastore` target and `db.system.name =
"postgresql"` for filtering and backend classification
- Exclude health-check database calls and scrub raw identifiers and
errors from newly traced paths

## Risk Assessment
Medium — this instruments frequently used datastore paths and increases
trace volume when enabled, but does not change SQL execution or
datastore behavior. Existing OpenTelemetry filtering controls export.

The HTTP bridge request log recorded route, status, and accepted but not
the event kind, so typing indicators (kind 7) and their deletions (kind
5)
were indistinguishable from real messages (kind 9). Every agent turn
produced
accepted:true lines whether or not a message was actually sent, which
twice
led debuggers to conclude a silent agent had published successfully.

Add kind to the Ok outcome and the tracing::info line so the publish

self-describing without a database query.

## Summary

- let Virtua own the initial visible timeline range instead of passing
every loaded row to `keepMounted`
- populate the existing bounded retention window after the virtualizer
reports its first settled viewport
- cover a 10,000-row timeline to prevent an all-history initial mount
regression

## Why

`useTimelineRetention` initialized its retained-key set with every
loaded timeline key. Those indices were passed to Virtua's
`keepMounted`, effectively defeating virtualization during initial
channel positioning until `onScrollEnd` pruned the set.

On a large real channel this grew WebContent into multiple gigabytes and
blocked the renderer main thread for 20+ seconds while WebKit laid out
and painted the retained rows. Starting with no retained rows restores
Virtua's visible-range mount; the existing reader-neighborhood and
visual-tail retention is populated once the viewport is measured.

## Validation

- `node --import ./test-loader.mjs --experimental-strip-types --test
src/features/messages/ui/useTimelineRetention.test.mjs`
- pre-push hook at `8e86a189de7e9a8f2cb119396c8f912ed9dacd6e`:
branch-skew, desktop-check, desktop-typecheck, and all 4,671 desktop

- manual ablation against PR block#5599 on the affected profile: catastrophic
channel-switch stalls disappeared

A NIP-25 reaction whose target is a project root or project comment
(kind
1621 issue, 1618 PR, or a kind-1 comment on one) carries no h tag, so
channel_id is None on the reaction write path. The conformance-trace
emission asserted a channel was always present:

channel: channel_label(channel_id.expect("reaction path has channel")),

so the worker panicked at ingest.rs:2824. The row was inserted before
the
panic, so the client saw a failed request for a persisted event and
retried,
and the duplicate branch carried the same expect, head-of-line blocking
a
durable publish queue forever.

Mirror the message write's three-way split at the same seam:
(Some, true) -> WriteInsert, (Some, false) -> WriteDuplicate, (None, _)
-> WriteInsertGlobal. The conformance vocabulary already models
channel-less
writes; only the reaction path was missing it.

The upstream sync combined block/buzz's own growth of runtime.rs with this
fork's local relay-dialing patch, pushing the file from 984 to 1008 lines --
over the desktop file-size ratchet's 1000-line cap.

Extract persona-drift classification, workspace-pair-key resolution, and the
ManagedAgentSummary builder into a new sibling module, runtime/summary.rs,
following this file's existing convention of splitting into sibling modules
(path, metadata, stop, sweep, process, orphan_sweep, instance_reaper,
lifecycle). Purely mechanical -- no behavior change.

Reviewed this as what it actually is — a 113-commit upstream sync, not hand-authored logic worth a line-by-line read. The job here is verifying the merge preserved what needs preserving and nothing broke, so I did that independently rather than trusting the PR body's own claims:

  • Pulled the actual file content at this PR's head and confirmed all three claimed fork-specific survivors myself: the <!-- launchpad-26 fork: begin/end --> banner in AGENTS.md (line 626-645), the 'Dial the relay the caller actually configured' comment in managed_agents/runtime.rs (line 234), and the 'Changed-paths filter contract' step in ci.yml (line 96).
  • Checked real CI on the PR directly rather than the locally-pasted results — all 29 checks pass, including adr-boundary, which is the automated check specifically built to catch exactly the kind of fork-boundary damage a bad upstream merge could cause.
  • Mobile shows green in real CI despite the PR noting 4 local pre-existing failures — consistent with the PR's own characterization of them as text-metric/environment-sensitive rather than a real regression, since a different CI runner environment plausibly doesn't hit the same accessible-text-size layout assertions.

The file-size-ratchet fix (extracting persona-drift/workspace-pair-key/summary-builder logic into a new runtime/summary.rs) follows the existing sibling-module convention already used for path/metadata/stop/sweep/etc. in that directory, so it's not introducing a new pattern.

Agreed on not squashing — flattening 113 upstream commits would make every future sync harder to reason about for no benefit.

Review: merge

Recommendation: merge, with a merge commit (not squash), and there's no need to sequence it around the open task PRs.

I reviewed this as a sync rather than 113 individual commits — verifying the merge strategy, fork-change survival, the one hand-authored follow-up commit, and interaction with in-flight work.

Strategy

True merge (523fb9ad9), same as the previous sync (PR #12's e24e960ee/5f5301d5b). Consistent and correct — and the "please do not squash" request is load-bearing: squashing would orphan the shared history with block/buzz and turn the next sync into a conflict storm.

Fork changes survive (verified independently, not from the PR body)

  • AGENTS.md:626-645 — fork banner block intact and contiguous.
  • .github/workflows/ci.yml:96 — fork-added "Changed-paths filter contract" step present.
  • managed_agents/runtime.rs:234 and restore.rs:336-342 — the dial-the-configured-relay fix survives in both files (&relay_url still passed at the spawn_agent_child call site).
  • Broader check: I diffed the fork's full delta vs upstream before and after the merge. Every file whose delta "changed" traces to launchpad PRs #184#195 that landed after this branch was cut — none overlap the sync's changed paths, and GitHub reports the PR mergeable on the current base. Nothing launchpad-local was clobbered.
  • The four overlap files were auto-resolved by git (empty combined diff on the merge commit) — no bespoke hand resolution to second-guess.

Follow-up commit 43366affa

Verified mechanical: the extracted functions land verbatim in runtime/summary.rs and are re-exported from runtime.rs:73-77; runtime.rs drops to 742 lines. Matches the directory's existing sibling-module convention.

CI

All substantive checks green, including adr-boundary (the check designed to catch fork-boundary damage from a bad merge). The two red "PR body check" runs are stale — the 03:59Z re-run after the body edit passes. The 4 local mobile-test failures are pre-existing (#215) and the real CI Mobile job is green.

Interaction with open task PRs (#213/#214/#222, #217, #219)

Zero path overlap — they live entirely under launchpad/project-intelligence/ and launchpad/plans/, which this sync doesn't touch. They can land before or after with no conflicts; I'd still land this promptly since it's the big moving target.

Follow-up

+1 to landing #215 before the next sync so the --no-verify push doesn't have to recur.
