# Migrate storage from SQLite to PostgreSQL — full dashboard cutover Migrates Fusion's storage layer to the embedded PostgreSQL `AsyncDataLayer` (the default backend) and **completes the satellite-store + feature cutover** so every dashboard and Command Center surface works in PG mode. ## Status — every surface works in embedded-PG mode Verified live against a running embedded-Postgres dashboard (all **200**, zero 5xx) and gate-tested (**23 files / 99 tests** on embedded PG, plus engine-core 294 and ci-shape 63 in the blocking merge gate; core/engine/cli/dashboard typecheck clean). | Area | Surfaces | State | |---|---|---| | Satellite stores | workflows, todos, insights, research, missions, goals, mailbox | ✅ | | Views | artifacts, documents, evals | ✅ | | Command Center | activity, productivity, team, tokens, tools, **workflows**, **github**, **signals**, **plugin-activations**, **live** (all 10) | ✅ | | Run execution | insight generation, research run execution | ✅ (store-path; AI step needs a provider) | | Live updates | SSE push for mission/research/insight events | ✅ | | Workflow editing | create / update / delete / select (+ id counter) | ✅ | | Engine | mission autopilot, incident-signal ingestion, regression storm-guard, agent wake-on-message | ✅ | | Core | tasks, agents, secrets, automations, memory, chat, usage, PRs, git | ✅ | ## Approach Each satellite store gets an `Async<Store>` wrapper exposing the sync store's method names over the existing `async-*-store.ts` helpers; `get<Store>Store()` returns a `Sync | Async` union; consumers `await` (harmless on sync), and engine/CLI paths that can't convert use `instanceof Sync` graceful fallback. Analytics aggregators branch on `"ping" in dbOrLayer` to run schema-qualified raw SQL over `project.*` (snake_case) in PG. Executors/orchestrators/autopilot are await-converted to drive the union store; the async store wrappers extend `EventEmitter` so SSE live-push fires in both backends. Not-yet-ported capabilities degrade gracefully (never 500) and are individually called out in commits. ## Sync with main The branch is kept continuously merged with `main` (currently through FN-7845, 2026-07-12); the earlier "final rebase deferred" note no longer applies. Use **Create a merge commit** (or squash) to land it — GitHub's rebase-merge cannot replay a merge-maintained branch. ## Residual Review Findings Multi-agent code review of the PostgreSQL satellite-store ports (U1–U5) applied 3 safe fixes (see `fix(review): apply autofix feedback`). The following are **real but gated** — recorded here as follow-up work rather than auto-applied. All are SQLite→PostgreSQL **concurrency/atomicity regressions**: the sync stores were immune only by SQLite's single-writer, single-threaded-handler execution; the async ports open multi-await read-modify-write windows. **Reachability is low today** because the execution engines that generate concurrent same-run mutations (insight run executor, research orchestrator/dispatcher) are `instanceof`-gated to sync mode in PG. No process-crash class survived (all engine fallbacks correctly guard the sync store). - **[P1] Research `appendResearchEvent` dual-write is non-atomic** (`packages/core/src/async-research-store.ts`, corroborated: adversarial + reliability). The `research_run_events` insert (own transaction) and the `run.events` jsonb update are separate writes — a crash between them, or two concurrent appends, splits the table count from the jsonb array. **Fix:** perform the seq-insert and the jsonb update in one `layer.transactionImmediate`. - **[P1] Research run terminal-reversion via stale full-row persist** (`async-research-store.ts` `persistResearchRun`/`updateResearchStatus`). Concurrent `PATCH /runs/:id/status` + `POST /runs/:id/events` can revert a terminal run to `running` by overwriting the whole row, bypassing the transition guard. **Fix:** scoped column `UPDATE`s with a `WHERE status …` guard, or optimistic version column. - **[P2] `updateResearchRun`/`updateInsightRun` read-then-write TOCTOU** — concurrent PATCHes last-writer-wins on the lifecycle merge. **Fix:** `SELECT … FOR UPDATE` / enclosing transaction. - **[P2] `upsertRun`/`createRunOrThrowConflict` check-then-create race** (`async-insight-store.ts`) — two callers can each create an "active" run. **Fix:** partial unique index on `(projectId, trigger) WHERE status IN ('pending','running')`. - **[P3] `createResearchRetryRun` return-value divergence** — sync returns the pre-update `queued` snapshot; async returns the reloaded `retry_waiting` run (persisted state is identical). Pick one side for cross-backend parity. - **[P2/perf] Mission `getMissionWithHierarchy`/`getMissionHealth` N+1 fan-out** — O(milestones×slices) sequential round-trips hold one pool slot per request; can starve the pool for large hierarchies. **Fix:** batched/joined reads. - **Testing gaps:** no PG-mode concurrency tests (interleaved status/event mutations), no sync↔async parity assertion for the lifecycle-error codes, and no mission status/health rollup parity test vs the sync `MissionStore`. ~~Out of scope (deferred): AI run *execution* (insight/research) + mission autopilot + live SSE mission events remain sync-gated/degraded in PG mode.~~ **Since ported** — insight/research run execution, mission autopilot, and SSE live push all run on the async layer now, which also makes the concurrency findings above genuinely reachable; they remain open follow-ups. --- ## Update — 2026-07-12: production-readiness hardening & live acceptance Everything below landed on this branch since the description above was written: **Production blockers from review — fixed** - `recoverStaleTransitionPending` ported to the async layer (backend moves write + clear the crash-safe marker; startup/maintenance sweeps no longer throw). - Lost-update class fixed: `atomicWriteTaskJson`/`WithAudit` write changed columns only (full-row upserts silently resurrected stale fields across concurrent store instances — the "task stuck unplanned forever" bug). - First-boot **auto-migration**: booting the PG backend over a project with a legacy `fusion.db` migrates it automatically (loud failure, SQLite kept as backup), and the dashboard shows a one-time **"your data was migrated" banner** with the backup paths and a Need-help Discord link. - `pg_dump`/`pg_restore` discovered from common install locations for embedded-mode backups. - The PG suite is part of the blocking merge gate (`test:pg-gate`). **Multi-project isolation (PR #2007, merged into this branch)** - `project_id` partition key on tasks / archived tasks / config, `taskProjectScope` threaded through every scan/claim/count, per-project config rows, layer bound to the project at startup. - Review P1 follow-up: the shared cold-storage `archive.archived_tasks` table is also partitioned and all archived-board reads/counts/searches are scoped. - Schema drift self-heal generalized to schema-qualified columns so existing databases upgrade in place. **Other changes** - Node settings sync **removed** in PG mode (409 `settings-sync-disabled-postgres`) — nodes share state by connecting to the same database; auth sync kept (per-machine file). - Perf (review findings): `listTasks` pushes column filter + ORDER BY + LIMIT/OFFSET into SQL; `getConversation` capped to the most recent 200 messages. - Fixed a false "operator action required" pause-abort log fired on every successfully auto-merged task. **Live acceptance — PASSED (2026-07-12)** A sandboxed instance (isolated HOME, embedded PG, real Opus executor) ran a task through the complete cycle: create → triage (AI spec) → execute → in-review → AI squash-merge landed on the project's `main` → done. A write+read sweep of every data surface (settings, comments, documents, attachments + artifact bridge + artifact edit, chat with real generation, goals, missions, agent mail, secrets, workflows, memory, CC analytics) was green on embedded PG. **Known remaining work** - The per-project `config` PK re-key has no upgrade path for pre-isolation embedded-PG databases (needs a real `DROP CONSTRAINT`/re-key migration; fresh databases are fine). - `pg_dump`/`pg_restore` binaries are not yet bundled in release artifacts (PATH/common-location discovery only). - The satellite-store concurrency findings listed above. --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Co-authored-by: Phil Larson <hello@phillarson.xyz> Co-authored-by: fusion-merge <fusion-merge@local>

"$comment": "Flaky-test quarantine ledger (deletion ratchet \u2014 see AGENTS.md 'Flaky tests: quarantine on sight' and docs/testing.md 'Quarantine ledger and the deletion ratchet'). A test observed failing without a corresponding real bug is quarantined ON SIGHT: add an entry here AND a matching one-line `exclude` entry in that package's vitest config, in the same commit. Every entry needs a non-empty `reason` (link the failing run) and a `quarantinedAt` date \u2014 the entry expires 14 days later, at which point the test file is DELETED unless someone rescues it with evidence it catches real regressions plus a root-cause fix (never appeasement). There is deliberately no loader module and no automation around this file: it is a dated record, the vitest config exclude is the mechanism, and the sweep is policy executed by whoever touches the suite.",

"reason": "FN-7530 RESCUE-by-split of the prior extension.test.ts entry: the dist-barrel fn_task_list test timed out at 5000ms in the full-suite shard 4/4 (run https://github.com/Runfusion/Fusion/actions/runs/28697507894) while passing locally in ~1.2s and in 3 of the 4 surrounding CI runs. Root-cause invariant: the test does in-test module recompilation (vi.resetModules + vi.importActual of the full @fusion/core dist barrel + a fresh dynamic import of extension.js) inside the default 5s test timeout; that work is CPU-bound and degrades non-linearly under 4-shard CI contention (same loaded-lane signature as FN-6483/FN-6705/FN-6795/FN-6839). Widening the timeout is forbidden by the flaky-test rule and removing the recompilation removes the test's only purpose. The sibling source-@fusion/core test 'bounds large column-filtered listings' (extension.test.ts) covers the identical truncation invariant, so this test's marginal coverage is dist-resolution only, which has been stable -- it is isolated rather than deleted. Isolating this single test into its own file let the ~68 otherwise-stable tests in extension.test.ts return to the default lane immediately; only this narrowly-scoped file remains quarantined under its own fresh clock.",
