A paused engine with nothing running derived executorState "idle", so the
footer badge was indistinguishable from a healthy engine waiting for work.
That is exactly the state a pause settles into once in-flight tasks drain:
triage and planning stall while the board keeps moving, with the pause only
visible by opening the Engine Control menu. Pause state now dominates run
state; the adjacent counters still report throughput.
In the CLI TUI, the global `t` (Git view) branch returned before the Utilities
dispatch in the same key handler, so the advertised "[t] Toggle Engine Pause"
was unreachable dead UI. It now yields when Utilities owns input, and because
the shortcut can stop the board, pausing takes a second `t` within 5s while
resuming stays single-press.
Tests assert the invariant across the whole state matrix (both pause flags x
0/1/5 running), not just the zero-running repro, plus the TUI routing, the
two-press pause, single-press resume, and re-arm behavior.

Full Suite shard 4 timed out runTaskShow lock-exhaustion at the default 5s
budget (run 30096660913): each case re-imported the heavy task.js graph under
fake timers, so cold CI workers spent the whole budget on transform and left
unhandled store.getTask / process.exit races after the timeout.
Import task.js once per cached-store describe under real timers via a mutable
store holder, and enable fake timers only around the backoff body. Exhaustion
cases now finish in ~1ms locally while keeping the shipped entry path.
The CLI full-package build's nested @fusion/desktop build stages the
production closure via pnpm deploy (~1300+ packages); on cold-store macOS
release runners that exceeded runWorkspaceCommand's default 10-minute
timeout and killed every v0.73.0-beta.* bun-darwin-arm64 release leg with
exit 143. Raise the desktop sub-build budget to 30 minutes and widen the
build-binaries job timeout to 45 minutes to match.

Stale-test drift, no product changes: FN-8424 inbox reply help text and
fn message inbox --user routing, beta-track prerelease suffixes in version
regexes (0.73.0-beta.N), FN-8399 onMigrationProgress in createTaskStoreForBackend,
#2400 workflow-docs heading, and the durable planning-session store mocks for

Binary Release (v0.73.0-beta.5 was fully red):
- bun compile: mark chromium-bidi external — playwright-core@1.60 (feature-video)
optionally requires it and bun fails closed on unresolvable requires.
- Windows desktop EXE: quote -c.publish.channel=beta in release.yml; PowerShell
tokenizes the bare flag into `-c` + a path and electron-builder ENOENTs on it.
Full suite (all 4 shards red from stale-test drift, no product bugs found):
- engine: align mock stores/assertions with atomic store.moveTaskIf dispatch
(#2371), the fail-closed non-empty PROMPT.md artifact gate (#2390), oldest-
first admission (FN-8453), alreadyClaimed graph routing (#2393), startStep
step projection (#2403/FN-8464), structured retry presentation (FN-8503),
provider-lane pause reasons (#2339), typed column-boundary entry (#2378),
Type.Integer in CAS document schemas (#2375), bounded model-registry refresh.
- engine-no-blocking-shellout: re-pin 17 drifted allowlist line numbers and drop
the stale REBASE_HEAD entry whose execSync was removed.
- core: schema-applier expectations track migrations 0033-0035 (96 tables) and
the synthetic 0000 fixture gains workflow_work_items/mission_contract_assertions;
work-item terminal state is "succeeded" post-#2378.
Known follow-up (not addressed here): self-healing starved-refinement escalation
bumps task.priority, which FN-8453 oldest-first admission no longer consults.

Reported bug (screenshot): deleting the task created from a plan left the
session permanently stuck on PLANNING_CREATED_TASK_MISSING — Retry create
replayed the same 409 forever. A linked task absent from the
include-archived scan (task-row authority; a successful scan proves
deletion, not a flaky read) now clears the stale linkage and creates a
fresh task, in both the create-task route and createTaskFromPlanSession;
a still-listed-but-unreadable task keeps failing closed.
Multi-agent review of fdd120232 (correctness/adversarial/reliability):
- P1: CLI planning sessions were memory-only — setAiSessionStore only ran
in the dashboard server, so --resume could never find a session across
invocations. New ensureDurablePlanningSessionStore wires the durable
AiSessionStore over the board store's public asyncLayer in runTaskPlan.
- P1: resume failures now THROW instead of process.exit (fn_task_plan
runs inside the pi host — an exit killed the whole agent session), and
a no-question resume requires an explicit refine focus (the provided
description) so merely resuming never rotates the epoch.
- P2: claim and finalize CAS gained the same expected-epoch WHERE guard
as reconcile, so a stale-epoch creator can no longer finalize an
old-epoch task onto a rotated session.
- Side-effect failures (documents, logEntry, validate, reconcile) are now
logged instead of swallowed; post-insert failures no longer mislabel
the just-created task alreadyCreated:true; the keep-refining readline
closes on thrown prompts and a failed refine after creation returns the
created task id with a resume hint; cross-process generating guard
added to createTaskFromPlanSession.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Closes the P1 agent-native gap from the multi-task review: the CLI and
fn_task_plan pi tool created tasks via a raw store.createTask with no
proposalClaimId — no idempotency, no session linkage, and tasks outside
the epoch sequence, so a later dashboard Proceed would duplicate them.
- New shared createTaskFromPlanSession in @fusion/dashboard/planning:
the agent-surface twin of POST /planning/create-task (epoch-derived
claim key, claim/finalize/reconcile/release CAS lifecycle with the 30s
stale-lease takeover, formatPlanningPlanMd task shape, plan/original-
description documents, validate-on-create, generating guard).
- runTaskPlan creates through it (making the FN-7734 retry wrapper
genuinely safe), prints the session id, and offers an interactive
keep-refining loop that creates further tasks from the evolved plan.
- fn task plan --resume <sessionId> / fn_task_plan resumeSessionId reopen
an existing session — even a validated one whose task exists — and the
no-question resume regenerates the interview via a refine turn, which
rotates the creation epoch server-side.
Tests: CLI suite pins claim-aware creation, the continue prompt, and the
resume flow; dashboard suite pins createTaskFromPlanSession idempotent
replay and epoch-aware second creation.

## Summary
Every PR's blocking checks were dominated by redundant full rebuilds,
not by tests. Measured on recent runs: the Gate job spent ~6 of its ~7.5
min on a cold `pnpm build` (the exact-key dist cache missed on virtually
every PR) for ~45s of actual boot smoke + gate tests; Build ran ~8 min
and Typecheck ~4 min, both fully cold every time. Expected end state
once the warm job has run on main: all four blocking checks in roughly
2–4 min wall-clock.
### Gate job
- New `gate-dist-*` cache namespace with `restore-keys`, additionally
caching `.fusion/cache/plugin-build-cache.json` (build-workspace's
per-package content-hash skip cache) and `packages/cli/dist`. The
always-run `pnpm build` reconciles a near-match restore by content hash
and rebuilds only the packages the PR touched. This is safe *because*
the gate builds after restoring — the shard jobs' "no restore-keys" rule
(FN-4232/FN-4605 stale-dist incidents) still stands there, since they
consume dist without building.
- `FUSION_CLI_FULL_PACKAGE=0` on the gate build: skips the multi-minute
CLI desktop/plugins/DTS packaging tail nothing in the gate consumes
(same shape `pnpm verify:fast` proves locally). Full CLI packaging
coverage stays blocking in the Build job.
### Build job
- Restore-only tap (`actions/cache/restore`) of the same warmed cache.
Restore-only because this job runs FULL CLI packaging (`CI=true`) and
saving that shape would swap the cache's canonical fast-CLI contents out
from under the Gate job. Its distinctive coverage is preserved:
`ensureFullPackageCliPlanned` force-plans the CLI in full mode
regardless of cache state.
### Typecheck job
- Caches per-package tsc incremental buildinfo — self-validating (tsc
hashes every input against it and re-checks whatever changed), so
`restore-keys` is correctness-neutral by construction.
- **Fixes a real incrementality bug:** `tsconfig.json` and
`tsconfig.app.json` in the dashboard both inherited
`${configDir}/dist/.tsbuildinfo` from `tsconfig.base.json`, so the two
typecheck programs clobbered each other's buildinfo and re-checked the
full program every run — incremental typechecking never worked for the
dashboard, in CI or locally. `tsconfig.app.json` now writes
`dist/.tsbuildinfo-app`. Measured: dashboard typecheck 44s cold → 5.6s
warm.
### Warm job (full-suite.yml, push to main)
- New `warm-gate-build-cache` job saves both caches from main on every
push. Caches saved on a PR merge ref are invisible to other PRs, so
without this every PR's *first* run would still build/check cold.
## Guardrails
`ci-workflow.test.ts` pins the coupled invariants so they can't drift
apart silently:
- restore-keys requires the reconciling `pnpm build` after restore,
before boot smoke
- the mtime-defeating seed step stays exact-hit-only
- byte-identical cache path lists between the Gate/Build/warm blocks
(actions/cache versions caches by path list — a drifted list makes
caches mutually invisible)
- Build stays restore-only and must NOT opt out of full CLI packaging
- Typecheck cache shape + the distinct dashboard app buildinfo path
## Notes
- First PR runs after this lands still build cold until the warm job has
run once on main.
- No changeset: CI config + test-only per AGENTS.md.
## Verification
- `ci-workflow.test.ts` + `package-config.test.ts`: 106 tests pass
- Dashboard typecheck run twice locally: 44s cold → 5.6s warm, both
`.tsbuildinfo` and `.tsbuildinfo-app` written, exit 0
- Cache block path/key parity verified programmatically across both
workflow files

## Summary
Fusion npm installs now expose a working `agent-browser` command on
Windows, Linux, and macOS. Fusion publishes a top-level shim backed by
the exact pinned native package, preserving the existing Browser
Verification probe contract on every supported desktop OS.
## Validation
- Added a packed consumer-install matrix for `ubuntu-latest`,
`macos-latest`, and `windows-latest`.
- Each platform executes npm's generated shim, verifies `agent-browser
0.26.0`, and asserts the matching native binary is installed.
- Confirmed the packed Fusion manifest, installed dependency, and
command output all retain the exact declared version pin.
- Passed 101 focused CLI workflow/package tests, full workspace lint and
typecheck, strict changeset validation, and a real macOS ARM64
packed-install smoke.
## Post-Deploy Monitoring & Validation
- Search task logs for `agent-browser not found on PATH`, `Missing
native executable`, and Browser Verification availability warnings.
- Healthy signal: npm installs on Windows, Linux, and macOS resolve
`agent-browser --version` without missing-shim or native-payload errors.
- Failure signal: command resolution errors, version-pin mismatches,
missing native payloads, or increased browser-verification fast-bails.
- Validation window: first release cycle after publish; owner: Fusion
maintainers.
- Mitigation: revert the dependency and top-level shim if install
compatibility regresses.

## Summary
Re-lands the completed Fusion board task FX-005 on current upstream
`main`, stacked on #2374 (FX-004).
- adds a narrowly authorized additive publication path for archived task
documents
- preserves archived task and mission state and keeps ordinary
replacement/deletion writes rejected
- exposes retained archived current/revision reads
- requires project-scoped revision/hash CAS for publication
- maps malformed, unauthorized, missing, inconsistent, and stale states
safely
- rebases preserved dashboard drafts explicitly after CAS conflicts
## Why
Operators need to append a correction or evidence revision to an
archived task without unarchiving it or weakening ordinary archived-task
immutability.
## Dependency
This branch contains #2374 plus the eight FX-005 commits because
cross-fork PRs cannot target a fork-only base branch. After #2374 lands,
this PR should be rebased or refreshed so its diff collapses to FX-005
only.
## Validation
- PostgreSQL task-store and archived-default suites: 33/33
- dashboard route and editor suites: 321/321
- agent document tools: 22/22
- core, dashboard, and engine typechecks pass
<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit
* **New Features**
* Added optimistic concurrency controls for task document creation and
editing using revisions and content hashes.
* Added safe, authenticated append-only corrections for documents
retained on archived tasks.
* Archived documents and revision history remain available for direct
reading.
* Agent and dashboard tools now report conflicts clearly and support
explicit draft rebasing.
* **Bug Fixes**
* Prevented stale updates from overwriting newer document content.
* Preserved archived-task immutability while allowing controlled
corrections.
* **Documentation**
* Updated CLI, dashboard, storage, task-management, and agent guidance
for these workflows.

Post-extension modelRegistry.refresh() had no timeout, so a hung remote
catalog fetch left the TUI on "Loading extensions…" forever. Use a shared
15s-bounded refresh across dashboard/serve/daemon and related registration paths.
## Summary
Fusion can now ship on two release tracks. Betas are cut from `main` as
`vX.Y.Z-beta.N` (npm dist-tag `beta`, GitHub prerelease), stable
releases are promoted to a long-lived `release` branch and published to
`latest`, and users pick their track with the new `updateChannel` global
setting — via **Settings → General → Release channel** or `fn update
--channel <stable|beta>`. Previously everything was single-track: every
publish landed on `latest` and every update surface could only see it.
| | beta | stable |
|---|---|---|
| Cut from | `main` | `release` branch |
| Version | `X.Y.Z-beta.N` (changesets pre-mode) | `X.Y.Z` |
| npm dist-tag | `beta` | `latest` |
| GitHub Release | prerelease | latest |
| Homebrew tap / X draft | skipped | bumped / printed |
## How releasing works now
`pnpm release` prompts for the channel and **defaults to beta**, so
day-to-day releases are betas; stable is always an explicit choice.
Choosing stable from `main` triggers assisted promotion: the script
proposes the newest beta tag reachable from HEAD, verifies `release`
fast-forwards to it, then runs the whole stable release inside a
temporary git worktree on `release` — the primary checkout never leaves
`main`. Changesets pre-mode preserves changeset files across betas, so
the promoted stable release aggregates every changeset since the last
stable into one clean changelog entry.
## Design decisions
- **Every publish path names an explicit `--tag`.** A beta accidentally
landing on `latest` is the one unrecoverable failure of a dual-track
scheme, so nothing relies on npm's implicit default (`release.mjs`,
`version.yml`).
- **Beta channel resolves to semver-max of `latest` and `beta`**, so
beta users are offered each promoted stable once it overtakes their
prerelease. Switching beta → stable never downgrades; `fn update
--channel stable --force` is the explicit escape hatch.
- **One comparator instead of three.** CLI, dashboard, and desktop each
had their own `isRemoteNewer` that ignored prerelease identifiers —
`0.73.0-beta.2`, `-beta.3`, and `0.73.0` all compared equal, which
breaks the moment any beta exists. They now share full SemVer-precedence
helpers (`compareVersions`, `resolveUpdateTargetVersion`) from
`@fusion/core`.
- **Installs pin exact versions** (`@runfusion/fusion@0.73.0-beta.2`),
never a dist-tag, so an install can't silently land on the wrong track.
- **Desktop channels via electron-updater manifests.** Beta tags build
desktop artifacts with `publish.channel=beta` (emitting `beta*.yml`);
the app sets `channel`/`allowPrerelease` from the shared setting,
re-read on every manual check.
- **Update caches are channel-stamped** — a cache written for one
channel is never served to the other, so switching tracks takes effect
on the next check instead of after TTL.
## Test plan
- New unit coverage: SemVer precedence + channel resolution in
`@fusion/core` (30), channel behavior of the dashboard update check (28,
incl. 9 new) and `fn update` (16, incl. 8 new: persist `--channel`,
no-downgrade, `--force`, cache channel mismatch).
- `pnpm verify:fast` green (scoped typecheck, builds, CLI build, boot
smoke); desktop + settings-section suites green.
- `release.mjs` dry-run matrix exercised by hand: channel prompt
(default/override/invalid), branch preflights per channel,
assisted-promotion target selection, fast-forward guard against a
diverged `release` branch, and bootstrap when no `release` branch
exists.
- Not exercised live: an end-to-end publish (needs TTY authorization +
real npm publish). First real run is the first `pnpm release --channel
beta`.

## Summary
Windows installs with slow native dependencies now get five minutes to
finish, and a real timeout is reported as an actionable terminal retry
instead of a wall of preceding npm deprecation warnings. Registry
`ETIMEDOUT` errors keep their network diagnosis, including after the
legacy-bin `--force` retry.
Compound Engineering personas are now included in the published CLI
bundle, with complete source-to-staged coverage for all persona
definitions and a clear startup error if the bundled assets are missing
or empty.
The PostgreSQL statement visible in the report was validated by the
existing real-Postgres schema reapply test. Its actual `caused by`
detail was truncated, so this PR deliberately makes no speculative
database change.
## Validation
- Dashboard updater tests: 22 passed
- CLI updater tests: 16 passed
- CE persona installer tests: 7 passed
- Published bundle persona assertion: passed against every source
persona
- CLI and CE plugin typechecks: passed
- Changed production/config lint and strict changeset validation: passed
- Real PostgreSQL schema reapply integration test: passed

* Persona assets are reliably included in plugin builds and bunded
persona installation now errors clearly when definitions are missing or
empty.
* **Tests**
* Expanded update and bundling coverage for the new 5-minute timeout and
error-handling scenarios.

## Summary
Repeated review and executor sessions could replay a follow-up creation
step and produce another live task whenever the wording changed. In the
incident behind this fix, 21 creation calls for three intended
follow-ups left 18 duplicate tasks.
Agent-created tasks now retain their parent and agent provenance across
step sessions, heartbeats, and the published CLI surface. Same-parent
paraphrases converge on the existing task through a serialized pre-check
and a database-backed intent claim, while distinct sibling actions
remain separate. Candidate lookup is parent-indexed, uniqueness failures
abort creation, and canonical reuse no longer emits misleading creation
audit events or workflow claims.

## Validation
- Core duplicate guard and intake: 24 tests passed
- Engine task creation and heartbeat: 154 tests passed
- CLI extension: 66 tests passed, 95 skipped

* Preserved parent-task and agent context for created follow-ups.
* Concurrent follow-up requests are now serialized/deduplicated so
duplicates link to the existing task instead of showing as newly
created.
* Updated agent follow-up/heartbeat activity so reused follow-ups no
longer appear in run results as fresh creations.
