+summary: Default local backend is now embedded PostgreSQL; set FUSION_NO_EMBEDDED_PG=1 for legacy SQLite.
+category: feature
+dev: `createTaskStoreForBackend` now boots embedded PostgreSQL by default when DATABASE_URL is unset (previously required FUSION_EMBEDDED_PG=1). FUSION_EMBEDDED_PG=1 is now a no-op alias; FUSION_NO_EMBEDDED_PG=1 is the opt-out back to legacy SQLite. `embedded-postgres` is now a direct dependency of @runfusion/fusion so the bundled CLI can resolve the platform binary at runtime. Boot smoke exercises the embedded path by default (initdb-aware 180s health timeout). Also hardens three backend-mode gaps the flip exposed: ResearchStore/insights router/watch() now degrade gracefully instead of crashing `fn serve` when the sync SQLite satellite stores are unavailable in PG backend mode.

+summary: CLI agent tools now boot PostgreSQL instead of the removed SQLite runtime.
+category: fix
+dev: The extension's getStore(cwd) path constructed a legacy SQLite TaskStore (runtime removed under VAL-REMOVAL-005), and the fn_agent_* tools constructed AgentStore without an asyncLayer — both threw "SQLite Database class body has been removed" in PG mode. getStore now routes through createTaskStoreForBackend (mirroring fn serve) and caches the boot result for deterministic shutdown; a new getAgentStore(cwd) helper injects the project store's asyncLayer into AgentStore so agent data lives in PostgreSQL. CLI extension tests were migrated to a shared PG harness (pg-extension-harness.ts) backed by an isolated test database with a test-only store-injection hook (__setCachedStoreForTesting).

+dev: The async store wrappers (AsyncMissionStore/AsyncResearchStore/AsyncInsightStore) now extend EventEmitter and emit the same events as their sync counterparts at the same mutation points (after the persistence await), so the SSE handler's subscriptions fire in PG mode instead of no-op'ing. sse.ts/server.ts drop the instanceof-sync narrowing and subscribe to the union store in both backends. Live push for mission/milestone/slice/feature/assertion/validator-start, research run lifecycle, and insight create/update events. Validator-loop-completed and fix-feature emits remain sync-only (those methods aren't in AsyncMissionStore yet).

+category: fix
+dev: The agent-log buffer flush/append path (flushAgentLogBufferImpl, appendAgentLogBatchImpl, appendAgentLogImpl) dereferenced the SQLite-only `store.db` getter — which throws in PG backend mode — on an unref'd retry-timer and inside catch handlers, so a handled flush error became an uncaught exception that exited `fn serve` (~35s uptime). Guarded the deleted-task pre-filter and `bumpLastModified` with `!store.backendMode` and replaced every `store.db.path` log interpolation with the mode-safe `store.fusionDir`. Also schema-qualified raw async SQL that referenced project-schema tables unqualified / with camelCase columns: `project.deployments` + `project.incidents` with snake_case `deployed_at`/`opened_at`/`resolved_at` (the deployments read sat outside the try/catch and 500'd `/api/command-center/activity`), `project.experiment_session_records` (+ `::jsonb` cast on the payload update), and `project.agent_runs`. Adds a backend-mode regression test pinning the no-`store.db`-deref invariant across all three agent-log entry points.

+
+# Migrate storage from SQLite to PostgreSQL (embedded + external)
+
+## Summary
+
+Replace the SQLite storage layer with PostgreSQL following the Paperclip model: a bundled embedded Postgres binary (npm `embedded-postgres`) provides zero-config local storage, `DATABASE_URL` switches to an external server, and SQLite is removed after a dual-read cutover. The data layer is rewritten on Drizzle ORM (schema-as-code, type-safe), which also forces the entire synchronous `DatabaseSync` data-access surface to become async.
+
+## Problem Frame
+
+Fusion persists all project, central, and archive state in three SQLite files (`fusion.db`, `fusion-central.db`, `archive.db`) accessed through a synchronous `DatabaseSync` adapter over `node:sqlite`/`bun:sqlite`. This works for single-machine, multi-process use under WAL, but it couples the application tightly to SQLite-specific features (FTS5 + triggers, JSON1 functions, PRAGMAs, `ATTACH DATABASE`, corruption self-healing) and blocks any multi-host or managed-database deployment. The goal is a single PostgreSQL backend that preserves zero-config local operation while enabling an external server, matching the architecture Paperclip (`github.com/paperclipai/paperclip`) uses: embedded Postgres by default, `DATABASE_URL` to point elsewhere.
+
+The dominant cost is not dialect conversion but the **sync-to-async conversion**: the `DatabaseSync` interface is synchronous and every Postgres client is async, so every database call site across the ~17k-line `store.ts` and ~5.9k-line `db.ts` must become awaited, independent of the query layer.
+
+---
+
+## Requirements
+
+### Backend topology and packaging
+
+- R1. When `DATABASE_URL` is unset, the application starts an embedded PostgreSQL instance (real Postgres process via `embedded-postgres`) into a local data directory, runs migrations, and serves with no external setup required.
+- R2. When `DATABASE_URL` is set, the application connects to the specified external PostgreSQL server (local Docker, managed/hosted, or any reachable server) and does not start an embedded instance.
+- R3. The embedded PostgreSQL binaries are bundled/shipped so `fn` works fully offline with zero system Postgres install on supported platforms (macOS, Linux, Windows; arm64 and x64).
+- R4. A separate `DATABASE_MIGRATION_URL` is honored for startup schema work when the runtime `DATABASE_URL` uses a transaction-pooling connection (Supavisor/PgBouncer), mirroring the Paperclip split.
+
+### Data layer
+
+- R5. All schema is defined as Drizzle ORM code (schema-as-code) and all data access goes through Drizzle against a PostgreSQL backend.
+- R6. The synchronous `DatabaseSync` data-access surface is replaced with an async data layer; no blocking/synchronous bridge to PostgreSQL remains.
+- R7. Existing behavioral invariants are preserved through the rewrite: soft-delete visibility (`deletedAt IS NULL` filtering across all live readers), task-ID allocator reconciliation on store open, lineage-integrity gates, document/artifact parent-task scoping, and the handoff-to-review `mergeQueue` transactional invariant.
+
+### Full-text search
+
+- R8. The FTS5-backed task and archive search is replaced with PostgreSQL full-text search (`tsvector`/`tsquery`, GIN indexes) preserving search-result parity and the automatic index-sync-on-write behavior that today's FTS5 triggers provide.
+
+### Migration and compatibility
+
+- R9. A migration tool moves existing SQLite data (all three databases) into PostgreSQL idempotently and verifiably.
+- R10. A dual-read cutover period is supported: during transition, SQLite is read-only and PostgreSQL is the write target, so deployments can migrate without downtime windows.
+- R11. After cutover, SQLite is fully removed (no dual-dialect abstraction retained long-term, no `better-sqlite3`/`node:sqlite`/`bun:sqlite` data-path dependency).
+
+### Health and maintenance
+
+- R12. SQLite-specific health and maintenance surfaces are reworked for PostgreSQL: corruption detection (`PRAGMA integrity_check`/`quick_check`) and the startup rebuild-on-malformed guard, compaction (`VACUUM`), WAL checkpointing, and the schema self-heal via `PRAGMA table_info`/fingerprint reconciliation.
+
+---
+
+## Key Technical Decisions
+
+- **Drizzle ORM for the full data-layer rewrite.** User-confirmed. The existing code is ~700KB+ of hand-written SQL against a sync `prepare()` interface with zero ORM; Drizzle gives schema-as-code, type safety, and a migration system. This is a near-total data-layer rewrite rather than a dialect conversion. Adopted over raw-SQL `postgres.js` (which would have preserved the architecture but offered no schema model).
+
+- **Sync-to-async conversion is mandatory and load-bearing.** The entire data layer is synchronous; every PostgreSQL client is async. Every `db.prepare(sql).get()` call site becomes `await`. Store methods are already `async`, so the boundary exists, but every internal database call must be awaited. This dwarfs all other conversion work and drives sequencing.
+
+- **Bundle embedded PostgreSQL binaries for zero-config default.** User-confirmed. `embedded-postgres` manages `initdb`/`pg_ctl` lifecycle over platform-specific Postgres binaries (~30-50MB per platform). True offline zero-config like SQLite today, at the cost of heavier distribution and known platform edge cases (WSL2, unprivileged LXC containers, macOS dyld loading) that Paperclip also encounters.
+
+- **Backend resolution by `DATABASE_URL` (Paperclip model).** Unset = embedded (real Postgres process, supports multiple concurrent connections and thus preserves the existing multi-process access pattern that PGlite/WASM cannot). Set = external server. `DATABASE_MIGRATION_URL` splits schema work off pooled runtime connections.
+
+- **Snapshot final SQLite schema as the PostgreSQL baseline + fresh Drizzle migrations.** Reimplementing the 128 hand-rolled SQLite migrations (`SCHEMA_VERSION = 128`) in PostgreSQL dialect is pointless for a greenfield Postgres schema. The migration tool materializes the current final schema into PostgreSQL, and Drizzle's migration history starts fresh from that snapshot. The version-gate testing discipline (the institutional learning that fresh-DB tests cannot catch a skipped-on-upgrade migration) is carried forward into the Drizzle migration tests.
+
+- **Dual-read = SQLite read-only + PostgreSQL write target.** During cutover, writes go to PostgreSQL; reads fall back to SQLite for any path not yet ported or for verification. This is lower-risk than a dual-routing query abstraction and avoids two-writer contention. The institutional learning that two engines race task leases over the shared central SQLite DB is respected: the cutover must not run two writers against SQLite, and PostgreSQL's MVCC structurally removes the single-writer contention.
+
+- **Three-database topology preserved as PostgreSQL schemas or databases.** The project/central/archive separation is retained (project state, global registry, cold-storage archive), mapping each to a PostgreSQL schema or database rather than collapsing them.
+

+```
+
+### Sync-to-async conversion shape
+
+The current layering is: async store methods (`async createTask`) calling a synchronous DB layer (`this.db.prepare(sql).get()`). The rewrite inverts the inner layer to async Drizzle calls (`await db.select()...` / `await tx.insert()`). Because the store boundary is already async, callers above `TaskStore` are unaffected; the change is contained to the data layer's internal call sites. Transaction semantics move from SQLite `BEGIN IMMEDIATE` + `SAVEPOINT` to Drizzle transaction callbacks (`db.transaction(async (tx) => ...)`), which must preserve the per-mutation atomicity the current `transactionImmediate()` path guarantees.

+
+---
+
+## Scope Boundaries
+
+### In scope
+
+- PostgreSQL connection layer with embedded/external resolution and lifecycle management.
+- Drizzle schema definition for all existing tables across project, central, and archive databases.
+- Async rewrite of the data layer (`store.ts`, `db.ts`, `central-db.ts`, `archive-db.ts`, and satellite `*-store.ts` files).
+- Full-text search replacement (FTS5 to `tsvector`/GIN).
+- Health/maintenance surface rework.
+- SQLite-to-PostgreSQL data migration tool.
+- Dual-read cutover harness and SQLite removal.
+
+### Deferred to Follow-Up Work
+
+- Performance benchmarking and query-plan tuning against production-scale data (after the rewrite lands and real workloads run).
+- Managed-host deployment guides (Supabase/RDS connection string specifics beyond the `DATABASE_URL`/`DATABASE_MIGRATION_URL` contract).
+- Read-replica or connection-pooler deployment topology recommendations.
+- Central-DB multi-host replication across machines (the mesh/node replication that already exists is out of scope; only its storage backend changes).
+
+---
+
+## System-Wide Impact
+
+- **All `@fusion/*` packages** consume the data layer; the async conversion ripples into `@fusion/engine` (worktree DB hydration, self-healing) and `@fusion/dashboard` (health endpoint, DB-corruption banner, routes).
+- **Plugin stores** instantiate core's `Database`. The `fusion-plugin-roadmap` plugin has its own store layer on core's `Database` and pins schema versions. The backend swap must stay behind a stable data-layer interface so plugin stores keep working.
+- **Backup/restore** changes fundamentally: SQLite file-copy backups become PostgreSQL logical dumps (`pg_dump`/restore). `backup.ts` and the `BackupManager` pairing behavior (project + central pair) are reworked.
+- **CLI** (`fn db ...` commands, `--vacuum`, run-audit surfaces) changes surface and behavior.
+- **Distribution** grows by ~30-50MB per platform for bundled Postgres binaries; the desktop build (`packages/desktop`) and CLI bundling are affected.
+- **Concurrency model** shifts from SQLite WAL multi-process-over-one-file to a PostgreSQL server process, structurally resolving the documented central-DB task-lease race but introducing connection-pool and server-lifecycle management.
+
+---
+
+## Risks & Dependencies
+
+- **Async-conversion correctness.** Missed `await`s, transaction isolation drift from `BEGIN IMMEDIATE`, and changed lock semantics are the highest-severity regression vectors. Mitigation: characterization coverage of current transactional paths before rewrite; the merge gate (`pnpm test:gate`) as the authoritative signal.
+- **embedded-postgres platform failures.** Paperclip reports initdb failures on WSL2, unprivileged LXC, and macOS dyld. Mitigation: graceful fallback messaging; document unsupported environments; consider external-server fallback guidance.
+- **FTS search parity.** `tsvector` ranking and tokenization differ from FTS5; result ordering and recall may shift. Mitigation: capture current search result fixtures as characterization baselines before replacing.
+- **Data-migration fidelity.** Soft-delete visibility, JSON column fidelity (SQLite text-JSON to JSONB), FTS index rebuild, and `AUTOINCREMENT` sequence continuity must survive the copy. Mitigation: idempotent, row-count-verified migration with a dry-run mode.
+- **Plugin-store contract drift.** If the data-layer interface narrows, plugin stores break. Mitigation: keep the store contract stable; schema-version pinning continues to work against the new migration history.
+- **Distribution size and CI.** Bundled binaries change install size and may affect CI image caching; the desktop build pipeline must fetch/verify platform binaries.
+- **Per the standing rule, flaky tests are quarantined on sight.** The rewrite will surface pre-existing flakiness; quarantine, do not appease.
+
+---
+
+## Implementation Units
+
+### Phase 1 — Foundation: backend, connection, schema
+
+### U1. PostgreSQL connection layer and backend resolution
+
+- **Goal:** Resolve the backend at startup (embedded vs external via `DATABASE_URL`) and expose a Drizzle connection pool with the `DATABASE_MIGRATION_URL` split.
+- **Requirements:** R1, R2, R4
+- **Dependencies:** none
+- **Files:** `packages/core/src/postgres/connection.ts` (new), `packages/core/src/postgres/backend-resolver.ts` (new); touches startup wiring in `packages/core/src/central-core.ts` / `packages/dashboard/src/server.ts`
+- **Approach:** A resolver reads `DATABASE_URL` (external) or signals embedded mode (U2). Runtime queries use the resolved URL; schema/migration work uses `DATABASE_MIGRATION_URL` when present, else the runtime URL. Connection pooling defaults to a small pool; document the transaction-pooling caveat (prepared-statement incompatibility) that motivates the migration-URL split. **Precondition (de-risk before Phase 2):** validate the chosen Drizzle driver bundles cleanly under the desktop Bun `--compile` build by probing both `postgres.js` and `pg` against the real `packages/desktop` build — the current `sqlite-adapter.ts` exists precisely because Bun `--compile` mishandles certain native modules, so this must be confirmed before the rewrite depends on it.
+- **Patterns to follow:** Paperclip `DATABASE.md` connection-mode table; the existing settings-resolution hierarchy in `packages/core/src/settings-schema.ts`.
+- **Test scenarios:**
+  - Happy path: unset `DATABASE_URL` resolves to embedded mode; set `DATABASE_URL` resolves to external and skips embedded start.
+  - `DATABASE_MIGRATION_URL` present routes schema work to it while runtime uses `DATABASE_URL`.
+  - Invalid/unreachable `DATABASE_URL` fails loudly with an actionable message.
+  - Pooled runtime URL with no `DATABASE_MIGRATION_URL` warns about prepared-statement risk.
+  - Security: the connection string (including any password in `DATABASE_URL`) is never written to logs, and connection-error messages redact credentials.
+- **Verification:** Startup logs the resolved backend and connection target; a health probe succeeds against the resolved backend.
+
+### U2. Embedded PostgreSQL lifecycle manager
+
+- **Goal:** Manage an embedded Postgres process (`initdb`, ensure database exists, `pg_ctl` start/stop) over a local data directory using `embedded-postgres`.
+- **Requirements:** R1, R3
+- **Dependencies:** U1
+- **Files:** `packages/core/src/postgres/embedded-lifecycle.ts` (new); bundled binary acquisition in `packages/desktop/scripts/build.ts` and `package.json` (`optionalDependencies`/postinstall)
+- **Approach:** On first start, `initdb` into the data directory, create the application database, run migrations, then serve. Persist across restarts; deleting the directory resets local state (mirroring the current SQLite reset behavior). Acquire platform/arch binaries (`embedded-postgres` supports macOS/Linux/Windows, arm64/x64). Handle graceful shutdown (`pg_ctl stop`) on process exit.
+- **Patterns to follow:** Paperclip embedded flow (`~/.paperclip/instances/default/db/`); the existing process-supervision discipline (`superviseSpawn` from `@fusion/core` — do not use raw detached spawn/nohup per AGENTS.md).
+- **Test scenarios:**
+  - Happy path: first start runs `initdb`, creates DB, runs migrations; second start reuses the directory without re-init.
+  - Existing data directory with prior schema starts without re-running init.
+  - Graceful shutdown stops the Postgres process; no orphaned process remains.
+  - Corrupt/locked data directory surfaces a clear error rather than hanging.
+- **Verification:** The application serves with no external Postgres installed; the data directory persists state across restarts.
+
+### U3. Drizzle schema definition (schema-as-code baseline)
+
+- **Goal:** Define the complete PostgreSQL schema in Drizzle for all existing tables across project, central, and archive databases, materialized from the current final SQLite schema (snapshot, not the 128 incremental migrations).
+- **Requirements:** R5
+- **Dependencies:** U1
+- **Files:** `packages/core/src/postgres/schema/` (new, organized by database: project, central, archive); Drizzle config (`drizzle.config.ts`); fresh migration directory
+- **Approach:** Translate every existing table (tasks, branch_groups, mergeQueue, config, workflow_steps, activityLog, task_commit_associations, archivedTasks, automations, agents, agentHeartbeats, approval_requests(+audit), secrets, task_documents(+revisions), artifacts, __meta, goals, missions hierarchy, plugins, routines, roadmaps, todos, chat tables, runAuditEvents, research/eval/experiment tables, etc.) into Drizzle table definitions. Map SQLite types: `INTEGER PRIMARY KEY AUTOINCREMENT` to identity/serial, JSON text columns to `jsonb`, the FTS5 tables to U7's tsvector design. Preserve all CHECK constraints, foreign keys with cascade rules, and unique indexes.
+- **Patterns to follow:** Existing schema declarations in `packages/core/src/db.ts` (`SCHEMA_SQL`, `MIGRATION_ONLY_TABLE_SCHEMAS`) as the source of truth for the snapshot; Drizzle schema conventions.
+- **Test scenarios:**
+  - Happy path: applying the fresh Drizzle migration to an empty database yields a schema matching the current final SQLite schema (column-by-column, constraint-by-constraint).
+  - Every foreign-key cascade rule and unique index from the SQLite schema is present.
+  - JSON columns round-trip as JSONB with the same shape.
+  - Plugin-owned tables (roadmap milestones/features) are included via the plugin schema-init hook.
+- **Verification:** A schema-diff between a migrated PostgreSQL database and a fresh-Drizzle-applied database shows no structural differences.
+
+---
+
+### Phase 2 — Data-layer rewrite (sync to async, Drizzle)
+
+### U4. Async data-layer foundation (replace DatabaseSync)
+
+- **Goal:** Replace the synchronous `DatabaseSync` adapter with an async Drizzle-backed connection and the core CRUD/transaction primitives the stores depend on.
+- **Requirements:** R5, R6, R7
+- **Dependencies:** U1, U3
+- **Files:** `packages/core/src/postgres/data-layer.ts` (new); removes the sync `DatabaseSync`/`Statement` surface in `packages/core/src/db.ts`; `packages/core/src/sqlite-adapter.ts` (retained only for the dual-read period, then removed in U11)
+- **Approach:** Provide the async primitives stores need: prepared-statement-equivalent query helpers, `db.transaction(async (tx) => ...)` preserving the atomicity of the current `transactionImmediate()` path, and the run-audit-event-within-transaction behavior (`recordRunAuditEvent` inside the shared transaction). Define the stable data-layer interface plugin stores consume so the backend swap is invisible to them. The `getDatabase()` accessor's contract changes: it must return an async-capable connection rather than the synchronous `Database` (U15 converts the direct-`prepare()` consumers that relied on the sync shape).
+- **Patterns to follow:** Current transaction helpers (`Database.transaction()`, `transactionImmediate()`) in `packages/core/src/db.ts`; the run-audit-within-transaction pattern.
+- **Test scenarios:**
+  - Happy path: an insert + matching audit insert commit or roll back together.
+  - A failing mutation inside a transaction rolls back all writes including the audit row.
+  - Concurrent transactions do not observe partial writes.
+  - The plugin-facing data-layer contract compiles against `fusion-plugin-roadmap`'s store usage.
+- **Verification:** The foundation supports a representative store mutation (create task + audit) atomically and async.
+
+### U5. Decompose `store.ts` into cohesive modules
+
+- **Goal:** Break the ~17k-line `TaskStore` god-class into cohesive per-responsibility modules behind the existing `TaskStore` facade, as a pure behavior-invariant refactor that makes each subsequent migration independently landable.
+- **Requirements:** R5, R7
+- **Dependencies:** none (pure refactor, no backend change)
+- **Files:** `packages/core/src/store.ts` (extract); new modules under `packages/core/src/task-store/` (e.g. persistence, allocator, settings, lifecycle, merge-coordination, archive-lineage, branch-groups, workflow-workitems, audit, search, comments)
+- **Approach:** Extract the distinct responsibility areas into separate modules without changing behavior or the backend: task persistence + allocator reconciliation, settings, task lifecycle/moves + workflow transitions, soft-delete/archive/lineage, merge-queue + merge, branch-groups + PR-entities/threads, workflow work-items + completion handoff, audit/activity-log/run-audit, search, comments/attachments, goal/usage/plugin events, file-watching, task-ID-integrity. Keep the `TaskStore` class as a facade composing the modules so callers are unaffected. No async or Drizzle changes yet.
+- **Execution note:** Behavior-invariant by design — the existing gate (`pnpm test:gate`) plus `store-concurrent-writes` / `checkout-claim-mutex` tests verify the extraction for free. Per the mass-migration learning, this is a no-two-agents-share-a-file extraction, not a backend swap.
+- **Patterns to follow:** `docs/solutions/architecture-patterns/mass-migration-agent-fleet-orchestration.md` (verification-invariance for mechanical extraction).
+- **Test scenarios:**
+  - Test expectation: none -- behavior-invariant refactor; the existing gate and concurrent-write/mutex tests are the verification surface.
+- **Verification:** `pnpm test:gate` passes with no behavior change; the facade preserves every public method signature.
+
+### U6. Satellite stores and databases rewrite
+
+- **Goal:** Rewrite the central database (`central-db.ts`), archive database (`archive-db.ts`), and satellite stores (`message-store.ts`, `chat-store.ts`, `mission-store.ts`, `insight-store.ts`, `research-store.ts`, `eval-store.ts`, `experiment-session-store.ts`, `routine-store.ts`, `plugin-store.ts`, `goal-store.ts`, `todo-store.ts`, `reflection-store.ts`, `automation-store.ts`, `approval-request-store.ts`, `secrets-store.ts`, `agent-store.ts`) to async Drizzle, plus `worktree-db-hydrate.ts`.
+- **Requirements:** R5, R6, R7
+- **Dependencies:** U4
+- **Files:** the `*-store.ts` files in `packages/core/src/`; `packages/core/src/central-db.ts`, `packages/core/src/archive-db.ts`; `packages/engine/src/worktree-db-hydrate.ts`
+- **Approach:** Same sync-to-async, dialect-to-Drizzle conversion as U5, applied per store. The archive database (cold storage, append-only FTS) maps to its PostgreSQL schema with the lighter-touch tsvector maintenance. Worktree DB hydration copies task-scoped metadata into the worktree's connection (now a scoped query against the shared PostgreSQL backend rather than a separate SQLite file hydration).
+- **Patterns to follow:** Each store's current SQLite implementation; the central-DB concurrency note from the learnings (two engines racing leases — the new backend removes single-writer contention).
+- **Test scenarios:**
+  - Happy path per store: representative create/read/update/delete.
+  - Central DB: secret encryption round-trips; access-policy CHECK constraints hold.
+  - Archive: archived task snapshots persist and are searchable.
+  - Worktree hydration: task + dependency metadata is copied for the active graph; binary artifact files are not copied.
+- **Verification:** Each store's existing tests pass against PostgreSQL; the worktree-hydrate test passes.
+
+### U12. Migrate TaskStore persistence, allocator, and settings modules
+
+- **Goal:** Migrate the decomposed task-persistence, ID-allocator-reconciliation, and settings modules (from U5) from sync SQLite to async Drizzle.
+- **Requirements:** R5, R6, R7
+- **Dependencies:** U4, U5
+- **Files:** `packages/core/src/task-store/persistence.ts`, `packages/core/src/task-store/allocator.ts`, `packages/core/src/task-store/settings.ts` (from U5); `packages/core/src/distributed-task-id.ts`, `packages/core/src/task-id-integrity.ts`
+- **Approach:** Convert the persistence-module call sites to awaited Drizzle queries. Preserve soft-delete visibility (`deletedAt IS NULL`) across all live readers, create-class non-destructive inserts, and allocator reconciliation bumping each prefix sequence to `max(current, max(task suffix)+1, max(archived suffix)+1, max(reservation)+1)` on store open. Settings reads/writes move to Drizzle against the `config` table. Carry FNXC comments forward.
+- **Execution note:** Characterization coverage of allocator reconciliation before migration; the merge gate is the authoritative signal.
+- **Patterns to follow:** Current allocator reconciliation and soft-delete invariants in `docs/storage.md`.
+- **Test scenarios:**
+  - Happy path: create/read/update/delete a task end to end.
+  - Soft-delete: live readers hide `deletedAt` rows; forensic reads surface them.
+  - Allocator reconciliation: stale sequences self-heal to max suffix; soft-deleted/archived IDs stay reserved.
+  - Settings: read/update project and global settings round-trip.
+- **Verification:** Persistence, allocator, and settings tests pass against PostgreSQL.
+
+### U13. Migrate TaskStore lifecycle and merge-coordination modules
+
+- **Goal:** Migrate the task-lifecycle/moves/workflow-transitions and merge-queue/merge modules (from U5) to async Drizzle, preserving the transactional invariants.
+- **Requirements:** R5, R6, R7
+- **Dependencies:** U5, U12
+- **Files:** `packages/core/src/task-store/lifecycle.ts`, `packages/core/src/task-store/merge-coordination.ts` (from U5)
+- **Approach:** Convert move/handoff/merge call sites to awaited Drizzle. Preserve the handoff-to-review `mergeQueue` invariant: the column move, `mergeQueue` insert, and handoff audit fan-out run in one Drizzle transaction (`db.transaction`), so observers never see `column = "in-review"` without the matching queue row. Merge-queue leasing (priority-first + FIFO within priority, recoverable expired leases) maps to Drizzle transactions with row-level locking.
+- **Patterns to follow:** The handoff invariant and merge-queue lease semantics in `docs/storage.md` and `packages/core/src/store.ts`.
+- **Test scenarios:**
+  - Happy path: move a task through columns; hand off to review; acquire/release a merge-queue lease.
+  - Handoff invariant: column move + `mergeQueue` insert + audit are atomic; a failure rolls back all three.
+  - Merge-queue lease: priority-first ordering; expired leases recover without incrementing attempts.
+- **Verification:** Lifecycle and merge-coordination tests pass against PostgreSQL; the checkout-claim-mutex test passes.
+
+### U14. Migrate TaskStore remaining modules (archive/lineage, branch-groups, workflow work-items, audit, comments)
+
+- **Goal:** Migrate the remaining decomposed TaskStore modules (archive/lineage, branch-groups/PR-entities, workflow work-items/completion-handoff, audit/activity-log/run-audit, comments/attachments, goal/usage/plugin events) to async Drizzle.
+- **Requirements:** R5, R6, R7
+- **Dependencies:** U5, U12
+- **Files:** `packages/core/src/task-store/archive-lineage.ts`, `packages/core/src/task-store/branch-groups.ts`, `packages/core/src/task-store/workflow-workitems.ts`, `packages/core/src/task-store/audit.ts`, `packages/core/src/task-store/comments.ts` (from U5)
+- **Approach:** Convert each module's call sites to awaited Drizzle. Preserve lineage-integrity gates (live children block parent delete/archive; `removeLineageReferences` clears them), document/artifact parent-task scoping under soft-delete, and run-audit-event-within-transaction behavior. The search module is migrated here for query structure, paired with U7's tsvector index. File-watching and task-ID-integrity detection move to PostgreSQL-backed reads.
+- **Patterns to follow:** Lineage children, documents under soft-deleted tasks, and the artifact registry semantics in `docs/storage.md`.
+- **Test scenarios:**
+  - Lineage: deleting a parent with live children throws; `removeLineageReferences` clears them; archived/soft-deleted children do not block.
+  - Archive: archived snapshots persist and are searchable; unarchive restores.
+  - Audit: a mutation and its run-audit event commit or roll back together.
+  - Comments/attachments: add/update/delete round-trip on an active task.
+- **Verification:** Remaining TaskStore module tests pass against PostgreSQL.
+
+### U15. Migrate engine and dashboard direct-`prepare()` consumers
+
+- **Goal:** Convert the `@fusion/engine` and `@fusion/dashboard` consumers that bypass store methods and call the sync `Database`/`prepare()` surface directly, once `getDatabase()` returns an async connection (U4).
+- **Requirements:** R5, R6
+- **Dependencies:** U4, U6, U12
+- **Files:** `packages/dashboard/src/monitor-store.ts`, `packages/dashboard/src/server.ts` (store-construction sites passing `getDatabase()`), `packages/dashboard/src/routes/register-*.ts` (store-construction sites), `packages/engine/src` callers of `store.getDatabase()` and direct `prepare()` (self-healing, worktree hydration); the `packages/engine/src/worktree-db-hydrate.ts` path already covered by U6
+- **Approach:** Replace direct `db.prepare(sql).run/get/all` calls in dashboard stores (notably `monitor-store.ts`) and route handlers with awaited Drizzle queries or routed through the relevant async store. Update store-construction sites that pass the raw `Database` (`new ChatStore(store.getDatabase())`, `new AiSessionStore(...)`, `new ApprovalRequestStore(...)`) to pass the async connection or the owning store. Convert engine test/self-healing direct-`prepare()` sites to async Drizzle.
+- **Patterns to follow:** The async store-method boundary established in U4/U6; existing route store-construction patterns.
+- **Test scenarios:**
+  - Happy path: dashboard monitor deployments/incidents/metrics read and write via the async path.
+  - Each migrated route store constructs against the async connection and serves requests.
+  - Engine self-healing mutations that previously used direct `prepare()` persist via async Drizzle.
+- **Verification:** Dashboard and engine tests pass against PostgreSQL; no direct sync `prepare()` call sites remain in `packages/dashboard/src` or `packages/engine/src`.
+
+---
+
+### Phase 3 — SQLite-specific surfaces
+
+### U7. Full-text search replacement (FTS5 to tsvector/GIN)
+
+- **Goal:** Replace the FTS5 external-content tables and triggers (`tasks_fts`, `archived_tasks_fts`) with PostgreSQL `tsvector`/GIN full-text search, preserving result parity and automatic sync-on-write.
+- **Requirements:** R8
+- **Dependencies:** U3, U5, U6
+- **Files:** `packages/core/src/postgres/schema/` (fts columns/indexes); search-query paths in `packages/core/src/store.ts` (`searchTasks`) and the archive store; the FTS maintenance step in self-healing
+- **Approach:** Use generated `tsvector` columns over the indexed text columns with GIN indexes, kept in sync via PostgreSQL generated columns/triggers (preserving the automatic sync that today's FTS5 `ai`/`au`/`ad` triggers provide). The value-aware partial-update optimization (only changed text columns touch the index) maps to PostgreSQL only re-generating the tsvector when source text columns change. Replace the FTS5 corruption/maintenance self-healing step with PostgreSQL index health (`REINDEX`/autovacuum) and the bounded rebuild-on-bloat threshold logic.
+- **Patterns to follow:** Current FTS5 design and the `rebuildFts5Index()`/merge/optimize thresholds in `packages/core/src/db.ts`; the documented defer rationale in `docs/storage.md` (attached live-FTS investigation).
+- **Test scenarios:**
+  - Happy path: search returns the same tasks for a representative query set as the FTS5 baseline.
+  - Insert/update/delete keep the tsvector in sync automatically.
+  - Non-text mutation does not needlessly re-generate the index.
+  - Index rebuild on bloat threshold restores search without data loss.
+- **Verification:** Search-result fixtures captured pre-rewrite pass post-rewrite.
+
+### U8. Health and maintenance surface rework
+
+- **Goal:** Rework the SQLite-specific health and maintenance surfaces for PostgreSQL: corruption detection, startup rebuild-on-malformed, compaction, WAL checkpointing, and schema self-heal.
+- **Requirements:** R12
+- **Dependencies:** U4, U5
+- **Files:** `packages/core/src/db.ts` (integrity/VACUUM/WAL-checkpoint paths); `packages/dashboard/app/components/DbCorruptionBanner.tsx`; `packages/dashboard/src/routes` (health endpoint `taskIdIntegrity`); `packages/engine/src/__tests__/self-healing-db-corruption.test.ts`
+- **Approach:** Replace `PRAGMA integrity_check`/`quick_check` and the startup rebuild-on-malformed guard with PostgreSQL health checks (`pg_stat`/connection liveness) and a restore-from-backup path on corruption. Replace `VACUUM`/WAL checkpoint with autovacuum tuning plus an explicit `VACUUM`/`ANALYZE` operator command. Replace the schema self-heal via `PRAGMA table_info`/fingerprint reconciliation with an `information_schema`/`pg_catalog`-based check driven by Drizzle's known schema. Preserve the task-ID-integrity detector (duplicate IDs, cross-table collisions, sequence drift) against PostgreSQL.
+- **Patterns to follow:** Current integrity/VACUUM paths and the schema self-heal fingerprint mechanism in `packages/core/src/db.ts`.
+- **Test scenarios:**
+  - Happy path: healthy database reports green health.
+  - Task-ID integrity anomalies (duplicate IDs, sequence drift) are detected and surface the banner.
+  - Schema drift detection catches a missing column and reconciles it.
+  - Explicit compaction command runs `VACUUM`/`ANALYZE` and reports stats.
+- **Verification:** The health endpoint and corruption banner behave as before; the self-healing-db-corruption test passes in its PostgreSQL form.
+
+---
+
+### Phase 4 — Migration, cutover, removal
+
+### U9. SQLite-to-PostgreSQL data migration tool
+
+- **Goal:** Build a tool that snapshots the current final SQLite schema into PostgreSQL and bulk-copies all data (all three databases), idempotently and with verification.
+- **Requirements:** R9
+- **Dependencies:** U3, U5, U6, U7
+- **Files:** `scripts/migrate-sqlite-to-postgres.mjs` (new); `packages/core/src/db-migrate.ts` (snapshot reference)
+- **Approach:** Read each SQLite database, map types (text-JSON to JSONB, integers to appropriate types), stream rows into the PostgreSQL schema via Drizzle, rebuild the tsvector indexes, and verify row counts per table. Support a dry-run mode. Handle the soft-delete/deletedAt rows, JSON column fidelity, and `AUTOINCREMENT` sequence continuity (set sequences to max(id)+1). The tool targets the embedded or external PostgreSQL backend via `DATABASE_URL`.
+- **Patterns to follow:** The existing one-shot reconciliation scripts in `scripts/` (e.g. `reconcile-leaked-soft-deletes.mjs`) for the bounded, idempotent, dry-run-default shape.
+- **Test scenarios:**
+  - Happy path: a populated SQLite database migrates to PostgreSQL with matching row counts per table.
+  - Idempotency: re-running against an already-migrated PostgreSQL database is a no-op or a clean re-sync.
+  - JSON columns round-trip with identical shape.
+  - Sequences are set to max(id)+1 so new inserts do not collide.
+  - Dry-run reports the planned copy without writing.
+- **Verification:** A migrated PostgreSQL database passes the same store tests as a natively-created one.
+
+### U10. Dual-read cutover harness
+
+- **Goal:** Support a transition window where SQLite is read-only and PostgreSQL is the write target, so deployments migrate without a downtime window.
+- **Requirements:** R10
+- **Dependencies:** U9
+- **Files:** `packages/core/src/postgres/dual-read-harness.ts` (new); backend wiring touched in U1
+- **Approach:** A mode flag routes all writes to PostgreSQL while reads fall back to SQLite solely for parity verification (all live data paths are already on PostgreSQL by this point — U10 runs after U5/U6/U7 ported every store). Enforce SQLite read-only (reject writes) to prevent two-writer contention that the learnings warn races task leases. Provide a parity-check command that compares SQLite vs PostgreSQL read results for a sample of queries. The parity check must exclude search-result ordering — FTS5 (SQLite) and tsvector (PostgreSQL, from U7) rank and tokenize differently, so strict search ordering comparison would report false failures; search parity is validated separately against captured fixtures in U7, and the dual-read parity check compares row membership only for search. Document the operator sequence: migrate (U9) → enable dual-read → verify parity → disable SQLite (U11).
+- **Patterns to follow:** The dual-engine safety guidance in `docs/solutions/developer-experience/browser-testing-dashboard-from-worktree-safely.md` (the daemon/lease-race hazard).
+- **Test scenarios:**
+  - Happy path: in dual-read mode, a write lands in PostgreSQL and is readable from PostgreSQL.
+  - A write attempt against SQLite in dual-read mode is rejected.
+  - Parity check reports matching row membership for sampled queries, excluding search-result ordering.
+- **Verification:** A deployment can run in dual-read mode serving live traffic with PostgreSQL as the sole writer.
+
+### U11. SQLite removal, fresh migration baseline, and cleanup
+
+- **Goal:** Remove SQLite entirely after cutover: drop the SQLite data path and dependencies, establish the fresh Drizzle migration history as authoritative, and rework backup/restore for PostgreSQL.
+- **Requirements:** R11, R12
+- **Dependencies:** U10
+- **Files:** `packages/core/src/sqlite-adapter.ts` (remove), `packages/core/src/sqlite-validation.ts` (remove), SQLite paths in `db.ts`/`store.ts` (remove); `packages/core/src/backup.ts` (rework to `pg_dump`/restore); `package.json` (remove `better-sqlite3`); `plugins/fusion-plugin-even-realities-glasses/package.json`, `packages/desktop/scripts/build.ts`; `docs/storage.md`, `AGENTS.md` (SQLite-specific sections)
+- **Approach:** Delete the SQLite adapter and validation, the FTS5 probe, the `ATTACH DATABASE` archive path, and SQLite-specific maintenance. Make the fresh Drizzle migration history the sole schema authority with the version-gate testing discipline carried forward. Rework `BackupManager` to PostgreSQL logical dumps (project + central pairing preserved as separate dumps). Update operator docs to reflect the `DATABASE_URL`/embedded model.
+- **Patterns to follow:** The version-gate regression-test learning (seed-at-previous-version tests for skipped-on-upgrade detection), applied to Drizzle migrations.
+- **Test scenarios:**
+  - Happy path: the application starts, runs, and passes the full gate with no SQLite code path reachable.
+  - No `better-sqlite3`/`node:sqlite`/`bun:sqlite` import remains in the data path.
+  - Backup produces a restorable PostgreSQL dump; restore round-trips.
+  - Fresh Drizzle migration history applies cleanly to an empty database.
+- **Verification:** `pnpm verify:workspace` passes; grep for SQLite symbols in the data path returns nothing.
+
+---
+
+## Open Questions
+
+- **Project/central/archive as separate databases or schemas in one database.** Both are valid; separate databases mirror today's separate files most closely and simplify backup pairing, while schemas-in-one-database simplify embedded single-instance management. Resolve during U3; the data layer abstracts the choice either way.
+
+- **embedded-postgres version pin and checksum verification.** The bundled Postgres binaries need a pinned version and (per the external-integration evidence rule) a checksum or `upstream-pending-verification` marker. Confirm during U2.
+
+---

+title: Fix Workflow Runtime Cutover
+date: 2026-06-23
+status: planned
+---
+
+# Fix Workflow Runtime Cutover
+
+## Problem
+
+The workflow graph and workflow-column runtime paths are being made default, but the first cutover review found that the new dispatch path is not yet equivalent to the legacy scheduler/executor invariants. The work must move the cutover onto an isolated branch and make the new path safe before opening a PR.
+
+## Requirements
+
+- R1: Keep unrelated dashboard/cosmetic changes out of the workflow cutover branch.
+- R2: The workflow hold/release scheduler path must preserve dispatch safety: dependency, mission, filesystem/spec, pause, lease, node-routing, permanent-agent, overlap, oscillation, `maxWorktrees`, `maxConcurrent`, and semaphore behavior.
+- R3: `TaskExecutor.execute()` must prove the graph-default entrypoint preserves legacy recovery behavior, including inner executor requeues and mismatched store-row protection.
+- R4: The gate must be self-contained: every test referenced by `packages/engine/vitest.config.ts` must be tracked and committed.
+- R5: Legacy workflow flags should not remain user-facing experimental kill switches, but stale persisted values must be tolerated.
+- R6: Remove or neutralize unreachable legacy scheduler dispatch code so future fixes do not land in dead paths.
+- R7: Validate with lint, typecheck, build, gate, and targeted engine tests before PR.
+
+## Implementation Units
+
+### U1. Isolate Branch State
+
+Files:
+- `packages/dashboard/app/components/ScriptsModal.css`
+- `packages/dashboard/app/components/__tests__/ScheduledTasksModal.test.tsx`
+- `docs/plans/2026-06-23-001-fix-workflow-runtime-cutover-plan.md`
+
+Approach:
+- Commit the dashboard/cosmetic automations spacing changes on `main`.
+- Preserve workflow cutover work on a dedicated branch for review and rollback.
+- Ensure `main` is not left carrying uncommitted workflow cutover edits.
+
+Tests:
+- `pnpm --filter @fusion/dashboard exec vitest run app/components/__tests__/ScheduledTasksModal.test.tsx`
+
+### U2. Scheduler Dispatch Equivalence
+
+Files:
+- `packages/engine/src/scheduler.ts`
+- `packages/engine/src/hold-release.ts`
+- `packages/engine/src/__tests__/scheduler-workflow-cutover.test.ts`
+- `packages/engine/vitest.config.ts`
+
+Approach:
+- Move all live pre-dispatch gates into the workflow hold/release reservation path or a shared helper used by that path.
+- Fix capacity ordering so no task is marked starting or status-cleared until all reservation checks pass.
+- Preserve `maxConcurrent` and shared semaphore semantics without double-acquiring the executor semaphore.
+- Make the replacement gate test tracked and broad enough to cover the migrated invariants.
+
+Tests:
+- `pnpm --filter @fusion/engine exec vitest run src/__tests__/scheduler-workflow-cutover.test.ts`
+- `pnpm --filter @fusion/engine test:core`
+
+### U3. Executor Graph Entry And Recovery
+
+Files:
+- `packages/engine/src/executor.ts`
+- `packages/engine/src/__tests__/workflow-graph-task-runner.test.ts`
+- Targeted executor tests under `packages/engine/src/__tests__/`
+
+Approach:
+- Ensure graph execution preserves the original dispatched task identity.
+- Fix graph failure handling so inner executor self-heal/requeue is not overwritten by outer graph parking.
+- Ensure graph `prepareWorktree` does not pre-acquire or pass the repo root as a task worktree.
+- Restore direct `TaskExecutor.execute()` coverage for default-on graph behavior and recovery semantics.
+
+Tests:
+- Focused executor recovery/worktree/liveness tests affected by graph-default behavior.
+- `pnpm --filter @fusion/engine test:core`
+
+### U4. Remove Dead Legacy Dispatch Surface
+
+Files:
+- `packages/engine/src/scheduler.ts`
+- `packages/engine/vitest.config.ts`
+
+Approach:
+- After U2 coverage is in place, remove unreachable legacy todo dispatcher code or reduce it to any still-needed shared helpers.
+- Keep reporter emission and non-dispatch scheduler duties intact.
+
+Tests:
+- `pnpm --filter @fusion/engine typecheck`
+- `pnpm --filter @fusion/engine test:core`
+
+## Verification
+
+- `pnpm lint`
+- `pnpm typecheck`
+- `pnpm test`
+- `pnpm build`
+- `compound-engineering:ce-code-review mode:agent plan:docs/plans/2026-06-23-001-fix-workflow-runtime-cutover-plan.md`
+
+## Risks
+
+- The workflow path is central engine infrastructure; green gate alone is not enough if broad affected tests still show executor/scheduler invariant regressions.
+- Semaphore handling must avoid both failure modes found in review: bypassing capacity entirely and double-acquiring before the executor can run.

+# feat: Port remaining satellite stores to PostgreSQL AsyncDataLayer
+
+## Summary
+
+The embedded-PostgreSQL backend is the default local store, but several satellite stores were never ported off the synchronous SQLite path. Their getters throw `"<Store> is not available in PG backend mode"`, so the dashboard features 500 (now interim-503-guarded). This plan ports the remaining stores so their dashboard surfaces work against real Postgres, sequenced cleanest-first as independent per-store units: **workflow definitions → mailbox (MessageStore) → InsightStore → ResearchStore → MissionStore**. TodoStore (already shipped this session) is the reference pattern.
+
+Each unit lands as its own commit, removes the interim 503/throw for that store, and adds a `*.pg.test.ts` to the blocking `test:pg-gate` lane. Mission autopilot/SSE and CLI-only paths may remain partial — only the dashboard read/write surface is in scope per store.
+
+---
+
+## Problem Frame
+
+In PG backend mode (`store.backendMode === true`), the synchronous `store.db` getter throws. Satellite-store getters (`getInsightStoreImpl`/`getResearchStoreImpl` in `packages/core/src/task-store/remaining-ops-10.ts`, `getMissionStoreImpl` in `packages/core/src/task-store/remaining-ops-8.ts`) construct their store with `store.db` and therefore throw. Dashboard routes were given interim `503` guards this session; `/api/workflows` still 500s because `readAllWorkflowDefinitionsImpl` does a raw `store.db.prepare("SELECT * FROM workflows")`.
+
+Each store already has a partial `async-*-store.ts` helper module targeting the existing `project.*` Postgres tables, plus a shared PG test harness (`packages/core/src/__test-utils__/pg-test-harness.ts`). The work is: fill helper gaps (faithfully replicating stateful lifecycle logic), wrap them in an async store exposing the sync method names, return that wrapper from the getter in backend mode, convert the dashboard routes (and any unconditional non-fallback consumers) to `await`, and remove the interim guard.
+
+---
+
+## Requirements
+
+- **R1.** Each ported store's dashboard routes return HTTP 200 with real data against a live embedded-PG instance (no 500/503).
+- **R2.** The server stays up — no uncaught throws from store getters or async misuse on engine/SSE paths.
+- **R3.** `test:pg-gate` stays green and gains one `*.pg.test.ts` per ported store covering the dashboard-critical methods, including lifecycle/state-machine behavior where present.
+- **R4.** Stateful logic (status-transition validation, terminal-immutability, auto-timestamps, retry gates, fingerprint dedup, auto-seq) is replicated faithfully — the PG path must match the SQLite path's observable semantics.
+- **R5.** Legacy SQLite mode is unaffected — the sync store remains the path when `!store.backendMode`.
+- **R6.** Interim 503 guards added this session are removed for each store as it is genuinely ported.
+- **R7.** Consumers that already wrap the getter in try/catch graceful fallback are left as-is; only unconditional sync consumers reachable in PG mode are converted to `await`.
+
+---
+
+## Key Technical Decisions
+
+- **KTD1 — Async-wrapper-class pattern (mirror TodoStore).** For each store, add an `Async<Store>` class (in the existing `async-*-store.ts`) that holds the `AsyncDataLayer` and exposes the **same public method names** as the sync store, delegating to the module's helper functions. The getter returns it in backend mode; the sync class stays for SQLite. Consumers `await` the result (harmless on sync returns). Rationale: proven this session with `AsyncTodoStore`; keeps a single call path across both backends.
+- **KTD2 — Getter return type becomes a union.** `get<Store>Store(): <Store> | Async<Store>`; the cached field widens to `<Store> | Async<Store> | null`. Callers `await`. Rationale: avoids forcing the sync store to become async and avoids an interface extraction.
+- **KTD3 — Replicate lifecycle logic in the new helpers, not the routes.** `updateInsightRun`/`updateResearchRun`/`updateResearchStatus`/`createResearchRetryRun` carry the state machines (`VALID_*_TRANSITIONS`, `TERMINAL_*_STATUSES`, auto-timestamps, retry gate). The async helpers must reproduce these checks and throw the same `*LifecycleError` types. Rationale: R4; the routes already assume the store enforces invariants.
+- **KTD4 — Leave engine/CLI graceful-fallback consumers untouched; convert only unconditional reachable ones.** Insight's 3 engine reporters and Research's `project-engine` orchestrator init already try/catch — leave them (they degrade). Convert dashboard routes always; convert CLI/agent-tools calls that are unconditional and async-reachable. Rationale: R7, bounds blast radius.
+- **KTD5 — Sequence cleanest-first, one commit per store.** Workflows (1 method, 0 consumer changes) → Mailbox (mostly wired) → Insight (6 helpers, engine on fallback) → Research (12 helpers + machines + ~24 consumers) → Mission (71 helpers, 54 route methods, partial). Rationale: ship value early, isolate risk, keep each PR reviewable.
+- **KTD6 — Raw async SQL must schema-qualify `project.*` and use snake_case columns.** Per this session's earlier fixes (the connection does not put `project` on `search_path`). New helpers go through Drizzle schema objects (auto-qualified) where possible; raw `sql` must qualify. Rationale: avoids the `relation does not exist` / wrong-column class already fixed once.

+```

+
+## Implementation Units
+
+### U1. Port workflow-definitions read to the async layer
+
+**Goal:** `/api/workflows` returns 200 in PG mode (lists builtin + custom workflow definitions).
+
+**Requirements:** R1, R2, R5, R6.
+
+**Dependencies:** none.
+
+**Files:**
+- `packages/core/src/task-store/remaining-ops-8.ts` (`readAllWorkflowDefinitionsImpl`)
+- `packages/core/src/async-workflow-store.ts` *(new, or add a helper to an existing async module)* — `listWorkflowDefinitions(layer)` reading `project.workflows`
+- `packages/core/src/__tests__/postgres/workflow-definitions.pg.test.ts` *(new)*
+- `packages/core/package.json` (`test:pg-gate` list)
+
+**Approach:** `readAllWorkflowDefinitionsImpl` is the ONLY sync method in the workflow-definition read path — every caller (`register-workflow-routes.ts`, `board-workflows.ts`, `executor.ts`, `agent-tools.ts`, CLI) already `await`s `listWorkflowDefinitions`/`getWorkflowDefinition`. Add a `store.backendMode` branch that reads rows from `project.workflows` (ordered `created_at ASC`) via the async layer and maps them to `WorkflowDefinition` exactly as the sync branch does (parse `ir`/`layout` jsonb, default `kind`). Builtins are merged from code constants downstream — unchanged. No consumer conversion needed.
+
+**Patterns to follow:** `AsyncTodoStore` row-mapping; the existing sync row→definition mapping in `readAllWorkflowDefinitionsImpl`; schema object `schema.project.workflows`.
+
+**Test scenarios:**
+- Happy path: seed two custom workflows via the layer; `store.listWorkflowDefinitions()` in backend mode returns them plus enabled builtins, ordered by `createdAt`.
+- Empty: no custom rows → returns builtins only, no throw.
+- `kind` filter: `listWorkflowDefinitions({ kind })` filters correctly.
+- jsonb round-trip: `ir`/`layout` parse back to the stored object shape.
+- Covers R1: `GET /api/workflows` handler resolves (integration-level via the store method).
+
+**Verification:** `GET /api/workflows` → 200 with builtin workflows on a fresh embedded-PG instance; custom workflow created via API then listed; `test:pg-gate` green.
+
+---
+
+### U2. Close the mailbox (MessageStore) PG gap
+
+**Goal:** Mailbox/chat-send routes work in PG mode (the reported "mailbox send error" is gone).
+
+**Requirements:** R1, R2, R4, R5.
+
+**Dependencies:** none.
+
+**Files:**
+- `packages/core/src/message-store.ts` (the `isBackendMode()` branches)
+- `packages/core/src/async-message-store.ts` (only if a helper is missing)
+- `packages/dashboard/src/routes/register-messaging-scripts.ts` / `register-chat-room-routes.ts` (verify await; no expected change)
+- `packages/core/src/__tests__/postgres/message-store.pg.test.ts` *(new or extend satellite coverage)*
+- `packages/core/package.json` (`test:pg-gate`)
+
+**Approach:** MessageStore is already engine-runtime-owned with **dual-path construction** — `in-process-runtime.ts` builds it with `{ asyncLayer }` in PG mode, the class branches on `isBackendMode()`, and the 11 async helpers exist; consumers already `await`. This is NOT a full port — it is gap-closure. **Execution note:** Start by reproducing the exact mailbox-send failure against a live embedded-PG instance and capture the error; the fix is whichever specific `MessageStore` method still routes to `this.db` (or an unimplemented `isBackendMode()` branch) on the send path. Wire that one method through the matching async helper.
+
+**Patterns to follow:** existing `isBackendMode()` branches in `message-store.ts`; `async-message-store.ts` `sendMessage`/`getConversation` helpers.
+
+**Test scenarios:**
+- Happy path: `sendMessage` → `getMailbox`/`getConversation` round-trip in backend mode returns the sent message.
+- Read state: `markAsRead`/`markAllAsRead` then `getUnreadAgentToAgentCount` reflects the change.
+- Edge: empty inbox returns `[]`, no throw.
+- Covers R1: the mailbox send route path returns 200.
+
+**Verification:** Reproduce-then-confirm: the captured send error no longer occurs; mailbox round-trip via API returns 200; `test:pg-gate` green.
+
+---
+
+### U3. Port InsightStore
+
+**Goal:** Insights dashboard (list, runs, run events, cancel, retry, CRUD) works in PG mode.
+
+**Requirements:** R1–R7.
+
+**Dependencies:** none (independent of U1/U2).
+
+**Files:**
+- `packages/core/src/async-insight-store.ts` — add 6 helpers + `AsyncInsightStore` class
+- `packages/core/src/task-store/remaining-ops-10.ts` (`getInsightStoreImpl`)
+- `packages/core/src/store.ts` (`insightStore` field type, `getInsightStore()` return type, import)
+- `packages/dashboard/src/insights-routes.ts` (await calls; remove 503 guard at ~L326–333)
+- `packages/cli/src/extension.ts` (4 insight tool calls → await)
+- `packages/core/src/__tests__/postgres/insight-store.pg.test.ts` *(new)*
+- `packages/core/package.json` (`test:pg-gate`)
+
+**Approach:** Write the missing async helpers: `updateInsight`, `updateInsightRun` (**replicate** terminal-immutable check, `VALID_RUN_STATUS_TRANSITIONS`, auto-`completedAt`/`cancelledAt`, `run:completed` semantics), `listInsightRunEvents`, `countInsights`, `listStalePendingRuns`, `countInsightRuns`. Build `AsyncInsightStore` exposing sync names (`getInsight`, `listInsights`, `upsertInsight`, `updateInsight`, `deleteInsight`, `createRun`, `getRun`, `listRuns`, `updateRun`, `findActiveRun`, `appendRunEvent`, `listRunEvents`, `countInsights`, `countRuns`) delegating to helpers; generate ids/timestamps in the wrapper where the sync store does. Wire `getInsightStoreImpl` (backend → `AsyncInsightStore(getAsyncLayer())`). Convert `insights-routes.ts` handlers to `await` and delete the 503 guard. Convert the 4 unconditional CLI tool calls in `extension.ts` to `await`. **Leave** the 3 engine reporters (`backlog-pressure`/`dependency-blocked-todo`/`unlinked-missions`) on their existing try/catch fallback.
+
+**Patterns to follow:** `AsyncTodoStore` (`getTodoStoreImpl` union return, store.ts field widening); the sync `updateRun` lifecycle block in `insight-store.ts` (lines ~537–626) is the spec for `updateInsightRun`.
+
+**Test scenarios:**
+- Happy path: `createRun` → `appendRunEvent` → `listRunEvents` (auto-seq 1,2,3) → `updateRun` to `completed` sets `completedAt`.
+- Lifecycle: updating a terminal run throws `InsightLifecycleError("terminal_immutable")`; an invalid status transition throws `invalid_transition`.
+- Dedup: `upsertInsight` twice with the same `(projectId, fingerprint)` updates in place (same id, preserved `createdAt`).
+- Counts: `countInsights`/`listInsights` agree on a filtered set; `findActiveRun` returns the pending/running run.
+- Edge: `getInsight`/`getRun` on a missing id → `undefined`; empty list → `[]`.
+- Covers R1: `GET /api/insights` and `GET /api/insights/runs` return 200 with seeded data.
+
+**Verification:** `/api/insights`, `/api/insights/runs`, run-events, cancel, retry all 200 on a live embedded-PG instance; create→cancel→verify terminal; server survives; 503 guard gone; `test:pg-gate` green (incl. lifecycle assertions).
+
+---
+
+### U4. Port ResearchStore
+
+**Goal:** Research dashboard (runs CRUD, events, sources, results, status machine, exports, retry, search, stats) works in PG mode.
+
+**Requirements:** R1–R7.
+
+**Dependencies:** none (independent), but sequence after U3 — it reuses the same wrapper/lifecycle pattern and is the highest-friction store.
+
+**Files:**
+- `packages/core/src/async-research-store.ts` — add 12 helpers + `AsyncResearchStore` class
+- `packages/core/src/task-store/remaining-ops-10.ts` (`getResearchStoreImpl`)
+- `packages/core/src/store.ts` (`researchStore` field/return type/import)
+- `packages/dashboard/src/research-routes.ts` (await; remove 503 at ~L157–161)
+- `packages/dashboard/src/sse.ts` (research subscription — already optional-chained this session; upgrade to real subscription if the async store exposes events, else leave optional)
+- `packages/engine/src/agent-tools.ts` (5 research calls → await)
+- `packages/cli/src/extension.ts` (research tool calls → await), `packages/cli/src/commands/research.ts` (async-ify handlers)
+- `packages/core/src/__tests__/postgres/research-store.pg.test.ts` *(new)*
+- `packages/core/package.json` (`test:pg-gate`)
+
+**Approach:** Write 12 helpers: `updateResearchRun`, `listResearchRuns`, `deleteResearchRun`, `appendResearchEvent` (**dual-write**: `run.events` jsonb array + `research_run_events` table), `addResearchSource`, `updateResearchSource`, `setResearchResults`, `updateResearchStatus` (**replicate the full lifecycle machine** — status validation, per-status auto-lifecycle fields, auto-timestamps, lifecycle-event append, status-changed/completed/failed/cancelled/timed_out semantics), `requestResearchCancellation`, `createResearchRetryRun` (**replicate retry gate + lineage**: source must be failed/timed_out, attempt cap → `retry_exhausted`+`not_retryable`, `rootRunId`/`retryOfRunId`), `searchResearchRuns`, `getResearchExport`. Compose via `persistResearchRun` where the sync store does (source/results/status mutate-then-persist). Build `AsyncResearchStore` with all ~23 route method names; wire `getResearchStoreImpl`; convert `research-routes.ts` (await + remove 503). Convert `agent-tools.ts` (5) and CLI (`extension.ts` + `research.ts`) unconditional calls to await; **leave** `project-engine.ts` orchestrator init on its try/catch fallback.
+
+**Execution note:** Implement `updateResearchStatus` and `createResearchRetryRun` test-first against the sync semantics — they are the riskiest (the lifecycle machine spans `research-store.ts` ~377–448 and retry ~570–625).
+
+**Patterns to follow:** U3's `AsyncInsightStore`; the sync `updateStatus`/`createRetryRun` blocks in `research-store.ts` are the spec; `appendResearchRunEvent` helper for the table side of the dual-write.
+
+**Test scenarios:**
+- Happy path: `createRun` (status `queued`) → `updateStatus("running")` sets `startedAt` → `updateStatus("completed")` sets `completedAt` + `retryable=false`.
+- Lifecycle machine: each status sets its documented auto-lifecycle fields; invalid transition throws `ResearchLifecycleError`; terminal run is immutable for non-event fields; `"pending"` normalizes to `"queued"`.
+- Retry gate: retry on a `failed` run within cap creates a lineage-linked `retry_waiting` run; exceeding cap sets source `retry_exhausted` and throws `not_retryable`; retry on non-failed throws.
+- Dual-write events: `appendResearchEvent` appears in both `getRun().events` and `listRunEvents`.
+- Sources/results: `addSource`/`updateSource`/`setResults` round-trip via `getRun`.
+- Search/stats/exports: `searchRuns` matches query/topic/summary; `getStats` groups by status; `createExport`→`getExports`→`getExport` round-trip.
+- Covers R1: `GET /api/research/runs`, `PATCH /runs/:id/status`, retry, search all 200.
+
+**Verification:** Full research route surface 200 on live embedded-PG; a queued→running→completed run with events/sources/results persists and reloads; retry produces a lineage child; server survives; 503 gone; `test:pg-gate` green (machine + retry assertions).
+
+---
+
+### U5. Port MissionStore (dashboard surface; autopilot/SSE partial)
+
+**Goal:** Missions dashboard (list/summaries/health, mission+milestone+slice+feature CRUD, reorder, links, contract assertions, validator runs) works in PG mode. Autopilot and SSE mission events may remain disabled.
+
+**Requirements:** R1–R7 (scoped to the dashboard surface).
+
+**Dependencies:** U3, U4 (reuses the established wrapper/lifecycle pattern; largest surface, do last).
+
+**Files:**
+- `packages/core/src/async-mission-store.ts` — add `AsyncMissionStore` class over the existing 71 helpers; write any helper gaps for the 54 route methods (e.g. `getMissionWithHierarchy`, `listMissionsWithSummaries`, health rollups, `computeMissionStatus`, interview-state, `triageFeature`, `activateSlice`, `findNextPendingSlice`, `backfillFeatureAssertions` — confirm coverage during implementation)
+- `packages/core/src/task-store/remaining-ops-8.ts` (`getMissionStoreImpl`)
+- `packages/core/src/store.ts` (`missionStore` field/return type/import)
+- `packages/dashboard/src/mission-routes.ts` (await; remove 503 at ~L308), `packages/dashboard/src/goals-routes.ts` (remove mission 503 at ~L57; goal→mission routes)
+- `packages/cli/src/extension.ts` (~13 mission tool calls → await)
+- `packages/core/src/__tests__/postgres/mission-store.pg.test.ts` *(new)*
+- `packages/core/package.json` (`test:pg-gate`)
+
+**Approach:** The 71 helpers cover the entity surface (missions/milestones/slices/features/events/goal-links/assertions/validator-runs/lineage). Build `AsyncMissionStore` exposing the 54 route method names; many are composites (`getMissionWithHierarchy` = mission + milestones + slices + features assembled; `listMissionsWithSummaries` = missions + counts; health rollups = event/validator aggregation) — assemble these in the wrapper from helper reads, mirroring the sync store's composition. Wire `getMissionStoreImpl`; convert `mission-routes.ts` + `goals-routes.ts` (await + remove guards); convert the ~13 unconditional CLI mission calls in `extension.ts`. **Explicitly leave partial:** engine autopilot (`in-process-runtime.ts` try/catch fallback) and SSE mission events (`sse.ts`) — document that mission autopilot/live-SSE stay disabled in PG mode; only request/response dashboard reads/writes are in scope.
+
+**Execution note:** Confirm helper coverage for the composite/health/interview/triage methods before wiring; write missing helpers faithfully (reorder ordering, interview-state transitions, validator-run staleness). Given the surface, consider splitting U5 into read-surface (list/get/hierarchy/health) and write-surface (CRUD/reorder/links/validators) commits if it aids review.
+
+**Patterns to follow:** U3/U4 wrappers; existing `async-mission-store.ts` helper signatures; the sync `mission-store.ts` composition for hierarchy/summaries/health.
+
+**Test scenarios:**
+- Happy path: create mission → add milestone → add slice → add feature; `getMissionWithHierarchy` returns the assembled tree; `listMissionsWithSummaries` returns counts.
+- Reorder: `reorderMilestones`/`reorderSlices` produce the new order deterministically.
+- Links: `linkGoal`/`unlinkGoal` and `listGoalIdsForMission` round-trip; `linkFeatureToTask`/`unlinkFeatureFromTask`.
+- Assertions/validators: `addContractAssertion`→`listContractAssertions`; `startValidatorRun`→`getValidatorRunsByFeature`.
+- Health/status: `computeMissionStatus`/`getMissionHealth` reflect feature/validator state.
+- Edge: empty mission list → `[]`; missing mission → `undefined`/404.
+- Covers R1: `GET /api/missions`, `GET /api/missions/:id` (hierarchy), goal→mission routes all 200.
+
+**Verification:** Mission list + a created mission with full hierarchy 200 on live embedded-PG; reorder/link/assertion/validator round-trips; server survives; 503 guards gone from mission + goals routes; `test:pg-gate` green. Autopilot/SSE-partial documented.
+
+---
+
+## Scope Boundaries
+
+**In scope:** Dashboard request/response surfaces for workflow defs, mailbox, Insight, Research, Mission, against embedded/external Postgres; the async helpers and wrappers they require; PG-gate test coverage; removal of the interim 503 guards.
+
+### Deferred to Follow-Up Work
+- **GoalStore full port.** Goals routes keep their interim 503 (GoalStore has ~10 sync CLI consumers — `extension.ts`, `commands/mission.ts` — that would need async conversion). Out of this plan's dashboard-surface scope; `async-goal-store.ts` exists for a later unit.
+- **Mission autopilot + live SSE mission events in PG mode.** Engine autopilot and `sse.ts` mission subscriptions stay on graceful fallback (U5 ships read/write dashboard only).
+- **CLI command full async-ification beyond what each unit's reachable tool calls require** (e.g. `commands/research.ts` sync handler conversion is included only as needed for U4; broader CLI parity is follow-up).
+- **`listStalePendingRuns` background sweepers** beyond providing the helper (wiring the sweeper to the async path if it isn't already).
+- **SSE live-refresh events from the async wrappers** (Todo/Insight/Research/Mission async stores do not emit store events; UI updates land on next read). Matches the documented TodoStore gap.
+
+---
+
+## System-Wide Impact
+
+- **`store.ts` getter signatures widen to unions** (`<Store> | Async<Store>`) for insight/research/mission (todo already done). Only dashboard routes and the listed CLI calls consume these; engine consumers are on fallback. TypeScript will surface any missed sync consumer at compile time.
+- **Engine/CLI behavior in PG mode:** reporters and orchestrator inits continue to degrade gracefully (unchanged); converted CLI tool calls begin actually working in PG mode.
+- **Test gate grows** by one `*.pg.test.ts` per store; gate runtime increases modestly (shared harness, per-test DB).
+
+---
+
+## Risks & Dependencies
+
+- **R-RISK1 — Lifecycle-logic drift (high).** `updateInsightRun`, `updateResearchStatus`, `createResearchRetryRun` reimplement state machines; a subtle divergence corrupts run state silently. *Mitigation:* test-first against the sync spec; assert transition rejections and auto-field population explicitly (R4 scenarios).
+- **R-RISK2 — Missed sync consumer breaks at runtime, not compile (medium).** A consumer using the union store without `await` gets a `Promise` where it expects a value. *Mitigation:* the union return type makes most misuse a type error; grep each getter's callers per unit; the engine/CLI categorization (convert-vs-fallback) is enumerated in the porting maps.
+- **R-RISK3 — Raw SQL schema-qualification regression (medium).** New helpers must qualify `project.*`/snake_case (KTD6). *Mitigation:* go through Drizzle schema objects; reuse the harness; the earlier `deployments`/`agent_runs` fixes are the cautionary precedent.
+- **R-RISK4 — Mission surface underestimation (medium).** 54 route methods incl. composites; some helpers may be missing despite the 71-count. *Mitigation:* confirm coverage before wiring; allow U5 read/write split.
+- **Dependency:** Live verification needs a fresh embedded-PG instance (force-killing the cluster corrupts `postmaster.pid` → wipe `~/.fusion/embedded-postgres` before relaunch — observed this session). Docker `postgres:15` on a non-5432 port for `test:pg-gate` (a local Postgres already holds 5432).
+
+---
+
+## Verification Strategy
+
+Per unit: (1) `test:pg-gate` green with the new `*.pg.test.ts` (run against Docker `postgres:15`); (2) build, launch the sandboxed embedded-PG dashboard, hit the store's routes and confirm 200 with real data; (3) confirm the server survives past startup (no uncaught throw); (4) confirm the interim 503/throw is gone for that store. The pipeline's browser test (`ce-test-browser`) exercises the dashboard surfaces end-to-end.
+
+---
+
+## Sources & Research
+
+- Reference port (this session): TodoStore — `AsyncTodoStore` in `packages/core/src/async-todo-store.ts`, `getTodoStoreImpl` in `remaining-ops-10.ts`, `todo-store.pg.test.ts` in `test:pg-gate`.
+- Porting maps (two reconnaissance sub-agents, 2026-06-27): per-store sync API, async-helper coverage gaps, dashboard route method usage, consumer convert-vs-fallback categorization, and PG schema confirmation for Insight/Research/Mission/Message/workflows.
+- Prior session fixes informing KTD6: schema-qualification of `project.deployments`/`project.incidents`/`project.agent_runs`/`project.experiment_session_records`.
+- Shared PG test harness: `packages/core/src/__test-utils__/pg-test-harness.ts` (`createSharedPgTaskStoreTestHarness`, `pgDescribe`).

+# Code Review — SQLite → PostgreSQL Storage Migration
+
+**Date:** 2026-06-26
+**Branch:** `feature/postgres` reviewed against `origin/main` (merge-base `7d13f880b`)
+**HEAD:** `387cec1a7` — `feat: migrate storage from SQLite to PostgreSQL (squash)`
+**Reviewers:** 13 persona agents (ce-code-review multi-agent pipeline) + learnings researcher + deployment verification
+**Run artifacts:** `/tmp/compound-engineering/ce-code-review/20260626-084137-41a91d02/` (per-reviewer JSON)
+**Plan:** `docs/plans/2026-06-23-001-feat-migrate-sqlite-to-postgres-plan.md`
+
+---
+
+## Scope
+
+- 714 files changed, **+64,470 / −173,769**.
+- **42,858 lines** of new code under `packages/core/src/postgres/`, `packages/core/src/task-store/` (63 files), and 19 `async-*` satellite stores.
+- **388 deleted test files** (167 core, 123 dashboard, 73 engine, plugins); 53 new `__tests__/postgres/*.pg.test.ts` added; `scripts/lib/test-quarantine.json` +175 lines.
+
+## Verdict: **NOT READY TO MERGE**
+
+A well-architected migration that honors the plan's design (R1–R12 are all honored in *design*), but as a single 42k-line squash it ships with **7 P0 and ~27 P1 findings**. Three structural facts dominate:
+
+1. **The async rewrite repeatedly dropped guards the sync path still enforces.** Soft-delete write-conflict guards, handoff atomicity, and — most severely — entire merge-critical store methods were never given a `backendMode` branch, so they **throw on every merge in the default embedded-PG backend**.
+2. **The tests that protected those invariants were deleted, and the new PG tests do not run in CI.** No Postgres service is provisioned and the skip logic is inverted, so 42k lines of new data-layer code is effectively uncovered. This is the FN-5893 "deleted the repro, kept the bug" failure mode.
+3. **This is a mid-migration (dual-path) branch, not post-cutover.** Both SQLite and Postgres paths are live behind **289 `backendMode` branches**; R11 (SQLite removed) is intentionally incomplete. The unguarded methods below are un-migrated leftovers of an incomplete flip.
+
+The backup subsystem is independently broken three ways in the default embedded mode, and there is no first-class migration entry point.
+
+---
+
+## P0 — Critical (must fix before merge)
+
+| # | File:Line | Issue | Reviewer(s) | Conf |
+|---|-----------|-------|-------------|------|
+| 1 | `task-store/remaining-ops-6.ts:441` | **`getActiveMergingTask` throws in PG mode.** Calls `store.db.prepare(...)` with no `backendMode` guard; the `db` getter throws *"SQLite Database is not available in backend mode"*. The merge concurrency guard (callers `merger.ts:9755`, `project-engine.ts:2247`) fails on every merge. **Verified.** | api-contract | 100 |
+| 2 | `task-store/remaining-ops-6.ts:818` | **`upsertMergeRequestRecord` throws in PG mode** — unguarded `store.db`. Callers `merger.ts:8466`, `executor.ts:1970`, `self-healing.ts:828`, `project-engine.ts:1866`. Method must become async + all callsites awaited. | api-contract | 100 |
+| 3 | `task-store/remaining-ops-6.ts:845` | **`transitionMergeRequestState` throws in PG mode** — unguarded `store.db`. ~12 callers in `merger.ts`/`project-engine.ts`. The merge state machine cannot advance. | api-contract | 100 |
+| 4 | `.github/workflows/full-suite.yml` · `__test-utils__/pg-test-harness.ts:81` | **New PG tests don't run in CI.** No `postgres` service is provisioned and `PG_AVAILABLE` is always truthy (`PG_TEST_URL_BASE` defaults non-empty, `FUSION_PG_TEST_SKIP` never set), so the 57 `pgDescribe` suites fail with `ECONNREFUSED` or are dead. 42k lines of new data-layer code has no integration coverage in CI. | testing | 100 |
+| 5 | `postgres/pg-backup.ts:261` | **`pg_dump` connects to the wrong DB.** Connection string passed via `PG_CONNECTION_STRING` — not a libpq variable. With no `--dbname`/`PG*` vars it hits the system default (localhost:5432, current user); in embedded mode (random port) backups fail or target an empty DB. The FNXC comment documents the (good) intent but the env var is non-functional. **Verified.** | reliability | 100 |
+| 6 | `postgres/pg-backup.ts:302` | Same gap for **`pg_restore`** — restore targets the wrong server. **Verified.** | reliability | 100 |
+| 7 | `task-store/remaining-ops-1.ts:132` | **Soft-delete resurrection.** The `backendMode` branch of `atomicWriteTaskJsonWithAudit` blind-upserts the row with no `deletedAt` re-read and no `throwSoftDeletedWriteBlocked` — the guard the sync branch has (lines 144-167). A write to / racing a soft-deleted task silently resurrects it (R7 / VAL-DATA-005/006). **Verified the guard is absent.** | adversarial (corrob. correctness, learnings, testing) | 75 |
+
+> Note: #1–#3 and #7 are the same root cause as the structural P1 below (#13) — an incomplete sync→async flip — manifesting as hard runtime failures and data-integrity regressions on critical paths.
+
+---
+
+## P1 — High
+
+### Unguarded `store.db` on async-converted paths (all throw in PG mode, confidence 100, `api-contract`)
+| # | File:Line | Method / impact |
+|---|-----------|-----------------|
+| 8 | `task-store/remaining-ops-2.ts:438` | `renewCheckoutLeaseImpl` — checkout lease renewal throws; silently escalates to checkout expiry during active execution. |
+| 9 | `task-store/remaining-ops-2.ts:871` | `registerArtifactImpl` — preliminary taskId check at :871 sits *outside* the `register()` guard at :890; throws whenever `input.taskId` is set. |
+| 10 | `task-store/remaining-ops-6.ts:618, :662, :699` · `remaining-ops-2.ts:489, :509` · `workflow-ops.ts:24` | Workflow settings read/write (×6) + workflow-step creation — engine agent-tools and dashboard workflow/settings routes throw in PG mode. |
+| 11 | `task-store/remaining-ops-6.ts:460` | `findRecentTasksByContentFingerprint` — unguarded **and** uses SQLite-only `json_extract(...)`; near-duplicate intake breaks. |
+
+### Other P1
+| # | File:Line | Issue | Reviewer(s) | Conf |
+|---|-----------|-------|-------------|------|
+| 12 | `task-store/moves.ts:187, :702` | **Handoff-to-review atomicity broken.** `createCompletionHandoffWorkflowWork` runs its workflow-work cancel/upsert in their own fresh-pool transactions, not the outer handoff `tx`; an outer rollback leaves committed workflow-work / orphaned merge-gate rows (R7 mergeQueue invariant). Pool-exhaustion deadlock risk via nested `transactionImmediate` (`workflow-workitems-ops-2.ts:20`). | correctness | 75 |
+| 13 | `store.ts` (289 sites) | **The flip never completed.** 19 `async-*` stores added *alongside* unchanged sync stores with 289 `backendMode` branches; `agent-store.ts` (3202 L), `mission-store.ts` (4390 L), `central-core.ts` (4374 L) carry both paths. Every feature written twice; the SQLite-fallback path (`in-process-runtime.ts:239`, `asyncLayer` null) runs untested. Root cause of #1–#3, #7–#11. | maintainability (corrob. correctness, testing) | 100 |
+| 14 | `postgres/sqlite-migrator.ts:369` | **Migration data-corruption risk.** `resolveColumnMapping` joins `information_schema.columns` by column name only (no table predicate); `data` is `text` in `archived_tasks` but `jsonb` in 5+ tables → nondeterministic type classification → batch aborts on `::jsonb` mismatch. Fixtures pass, prod fails. | data-migration | 75 |
+| 15 | `postgres/sqlite-migrator.ts:596` | **Content-blind verification.** `targetRows >= sourceRows` with `ON CONFLICT DO NOTHING` cannot detect under-migration or content divergence on re-run; reports `verified` regardless. | data-migration + adversarial (agree) | 100 |
+| 16 | `dashboard/routes/register-signal-routes.ts:222` | `resolveIncident()` became async but the caller was not updated — **floating Promise**, incident-resolution errors silently dropped. | api-contract | 100 |
+| 17 | `dashboard/monitor-store.ts:170` | **Broken backend discriminator.** `'transactionImmediate' in db` always routes SQLite `Database` instances (which also expose `transactionImmediate`, `db.ts:5746`) to the async path → `resolveIncidentAsync` runs with a `DatabaseSync` as the Drizzle arg. | api-contract | 75 |
+| 18 | `postgres/migrations/0000_initial.sql:1436` | **Missing index on `source_parent_task_id`** → the lineage gate (`findLiveLineageChildren`/`removeLineageReferences`, run on every archive/delete) is a full `tasks`-table scan. | performance | 100 |
+| 19 | `task-store/async-merge-coordination.ts:255` | **N+1 in merge-queue lease acquire** — 2 round-trips per stale row inside the tx, on every merge attempt (20 stale rows = 40 sequential round-trips before the first lease). | performance | 100 |
+| 20 | `task-store/async-audit.ts:120, :252` | **`LIMIT` applied in JS, not SQL** — audit/activity queries pull the entire matching set then `.slice()`; `activity_log` has no rotation. | performance | 100 |
+| 21 | `task-store/async-persistence.ts:280` | `readLiveTaskRows` does an unbounded `SELECT * FROM tasks WHERE deleted_at IS NULL` (80+ cols, jsonb) on every board hydration — MB/request over the wire. | performance | 100 |
+| 22 | `postgres/credential-redact.ts:39` | Redaction misses `?password=` query-param URLs; logged verbatim by `DatabaseConnectionError`/`describeBackendForLog`. | security | 75 |
+| 23 | `postgres/embedded-lifecycle.ts:414` | SIGTERM/SIGINT handler `await this.stop()` but never re-raises → process hangs alive until SIGKILL after the cluster stops. | reliability | 100 |
+| 24 | `postgres/startup-factory.ts:292` | No timeout on `embeddedLifecycle.start()` — a stalled `initdb`/`pg_ctl` hangs startup forever. | reliability | 75 |
+| 25 | `postgres/pg-backup.ts:130` | Partial backup not cleaned up — central dump failure orphans the project dump; `listBackups()` counts it as a pair, skewing retention. | reliability | 75 |
+| 26 | `postgres/pg-backup.ts` (packaging) | **Backup broken end-to-end in embedded mode**: `pg_dump`/`pg_restore` not bundled with `@embedded-postgres/*` (only `initdb`/`pg_ctl`/`postgres`); `BackupManager` also throws standalone because the embedded URL resolves only at daemon start. Compounds #5/#6. | deployment + agent-native (agree) | 100 |
+| 27 | `cli/src/commands/db.ts` | **No `fn db migrate` command and no auto-migrate at startup.** First boot on the new embedded-PG default produces an *empty database*; existing SQLite data is invisible until a hand-written script runs `migrateSqliteToPostgres`. Silent data-loss trap. | agent-native + deployment (agree) | 100 |
+| 28 | `__tests__/postgres/create-task-reserved-id.pg.test.ts` | `TombstonedTaskResurrectionError` (FN-5208/FN-5233, an AGENTS.md repeat-regression incident) has zero PG coverage; 13 engine reliability-interaction tests + `soft-delete-stickiness-FN-5233.test.ts` deleted (they used the removed `inMemoryDb` option, not deleted code). This is the test that would catch #7. | testing | 100 |
+| 29 | `async-central-core.ts:1424+` | FNXC gap: 1789-line file, 3 FNXC comments; the concurrency-slot + mesh-state sections (the "important technical decisions" AGENTS.md requires marked) are unmarked. | project-standards | 75 |
+| 30 | `task-store/remaining-ops-1.ts`…`-10.ts` | `remaining-ops-1..10` (~9000 L) are explicitly un-categorized overflow modules (mixed domains, several >1000 L); `lifecycle-ops.ts` is a new 1241-line file mixing DB open, FS watching, and settings migration. | maintainability | 100 |
+
+---
+
+## P2 — Moderate
+
+- `moves.ts:626` — soft-delete guard also missing on `moveTaskInternal` backend path (sibling of #7). *(adversarial, 50)*
+- `moves.ts:629` — WIP capacity limit overrun: two concurrent backend moves into one slot both commit under READ COMMITTED. *(adversarial, 50)*
+- `task-store/audit-ops.ts:59` — `taskRow as unknown as TaskDetail` **bypasses deserialization**; hook consumers get raw JSON-string columns. *(maintainability, 100)*
+- `postgres/connection.ts:46` — default pool `max=10` may starve under `maxWorktrees`-level concurrent `transactionImmediate` holders. *(performance, 75)*
+- `postgres/postgres-health.ts:329` — `healSchemaDrift` `catch {}` swallows ALTER TABLE errors silently. *(reliability, 100; safe_auto)*
+- `postgres-health.ts:354/389` — `validateAndHealSchema` ALTER and `vacuumAnalyze` VACUUM run on the runtime pool, not the migration connection → fail under a transaction-mode pooler.
+- `sqlite-migrator.ts:471` — empty-string → NULL for `jsonb`; `NOT NULL jsonb` columns (`data`/`ir`/`step_ids`) abort the batch on legacy `''` rows. *(data-migration)*
+- `__test-utils__/pg-test-harness.ts:128` — `execSync('psql …')` violates the AGENTS.md execSync ban (not git plumbing; no timeout → can hang the vitest worker). *(project-standards)*
+- `0000_initial.sql:1425` — no partial index for the hot `WHERE deleted_at IS NULL AND column = ?` kanban read (forces bitmap-AND). *(performance)*
+- **9 quarantine entries are migration-caused mock drift, not flakes** (CE orchestrator, desktop `local-server`, dashboard `research-api`) — AGENTS.md forbids quarantining tests that fail *because of* the change; 14-day deletion clock expires **2026-07-09**. *(testing)*
+- `index.ts` — `detectLegacyData`/`migrateFromLegacy`/`getMigrationStatus` removed from the `@fusion/core` public index with no deprecation; `dist/index.d.ts` still referenced them. *(api-contract)*
+- `store.ts:389` / `plugin-store.ts:130` — `inMemoryDb` constructor option removed from `TaskStore`/`PluginStore` → TypeScript compile break for any external/plugin caller.
+- `.changeset/embedded-postgres-lifecycle.md` — freeform body, missing `summary:`/`category:`/`dev:` (gate warns; `--strict` fails). *(project-standards; safe_auto)*
+
+## P3 — Low
+- `.returning()` would collapse insert-then-select double round-trips (`async-branch-groups.ts:120`, `async-monitor.ts:203`, …). *(safe_auto)*
+- `searchTasks*` return unbounded result sets with no default cap (`async-search.ts:159`). *(safe_auto)*
+- Repeated `as unknown as Record<string,unknown>` settings casts (`settings-ops.ts:63`).
+- `flip-embedded-pg-default.md` filed `minor`/`feature` — a default-backend swap is arguably `major`/`breaking`.
+
+---
+
+## Learnings & Past Solutions (all honored in design, at risk in execution)
+
+- **`docs/soft-delete-verification-matrix.md`** — the acceptance contract for R7. Findings #7, #28 are direct hits; re-run the matrix GREEN against the async store before cutover.
+- **`docs/solutions/database-issues/schema-version-constant-must-equal-highest-migration.md`** — carry the version-gate discipline to the Drizzle journal; add a *seed-at-previous-state* upgrade test (not fresh-DB only).
+- **`docs/solutions/database-issues/task-field-silently-dropped-without-sqlite-column-mapping.md`** — round-trip every `Task` field through `updateTask→getTask→reopen` (the `audit-ops.ts:59` cast is this risk realized).
+- **`docs/solutions/integration-issues/engine-already-running-is-not-no-engine.md`** — the `taskClaims` two-write lease release must keep `BEGIN IMMEDIATE`-equivalent isolation (`SELECT FOR UPDATE`/serializable), not drift to plain READ COMMITTED.
+- **`docs/solutions/test-failures/schema-version-sweep-must-include-plugin-workspaces.md`** — sweep plugin version pins from repo root after the first Drizzle migration bump; the roadmap plugin's snake_case vs camelCase column mismatch (api-contract residual) is unaudited.
+
+---
+
+## Deployment — Go/No-Go (blocking items)
+
+1. No `fn db migrate` CLI (#27).
+2. No automated pre-migration SQLite backup (operator must manually `cp` `fusion.db`, `archive.db`, `fusion-central.db`).
+3. `pg_dump`/`pg_restore` not bundled (#26).
+4. No auto-migrate → empty-DB-on-first-boot data-loss for naive upgraders.
+
+The full checklist (pre-migration baseline row-count queries, dry-run, FTS parity spot-check, post-migrate verification, rollback via `FUSION_NO_EMBEDDED_PG=1`, 24h monitoring of pool/process/disk) is in the deployment-verification agent output under the run artifact directory.
+
+---
+
+## Residual Risks
+
+- Embedded mode hard-codes superuser password `"password"` (local-only, 127.0.0.1 + random port — parity with prior local SQLite trust; consider a random per-instance password at 0600).
+- Fixed `project`/`central`/`archive` schema names → two projects sharing one external `DATABASE_URL` clobber each other (no isolation).
+- `tsvector GENERATED ALWAYS AS STORED` adds write amplification on every unrelated task update (heartbeat/timing writes recompute the vector).
+- No `DATABASE_URL` format validation (`backend-resolver.ts:92`) — malformed URL fails only at connect.
+- `pgRowToTaskRow` shim re-serializes parsed jsonb back to strings for `fromJson()`; any new async path skipping it feeds parsed objects to `JSON.parse` → `'[object Object]'` garbage (not enumerated across all helpers).
+
+## Coverage
+
+- Confidence gate: no findings suppressed below anchor 75 except retained P0@75 (#7); ~4 testing/maintainability P2/P3 advisory items demoted to soft buckets.
+- All 13 reviewers returned results; 0 failures/timeouts.
+- Testing gaps: no concurrency tests for the atomicity/lost-update paths (#7, #12, WIP); no perf benchmark for the N+1 hot paths at realistic volume; migrator untested for cross-table type collision, non-superuser FK-order fallback, pre-populated-target verification, and jsonb round-trip.
+
+---
+
+## Suggested Fix Order
+
+1. **Restore the safety net:** #4 (provision Postgres in CI + fix `PG_AVAILABLE` probe) and #28 (rescue the deleted invariant tests) — so everything below is verifiable.
+2. **Unblock the default backend:** #1, #2, #3 and the #8–#11 unguarded `store.db` methods — complete the `backendMode` branches (this is finding #13, the incomplete flip).
+3. **Data-integrity guards:** #7, #12, #14, #15.
+4. **Backup / lifecycle:** #5, #6, #23, #25, #26, #27.
+5. **Performance:** #18, #19, #20, #21.
+6. **Standards / structure:** #16, #17, #22, #29, #30.

+ * FNXC:MissionStore 2026-06-27-16:15:
+ * Regression test for the dashboard boot blocker (VAL-CROSS-001/002/005/006).
+ *
+ * packages/cli/src/commands/dashboard.ts eagerly constructed MissionAutopilot
+ * and MissionExecutionLoop by calling `store.getMissionStore()` at startup.
+ * Originally `getMissionStore()` reached `store.db` which threw
+ * "SQLite Database is not available in backend mode", crashing the entire
+ * `fn dashboard` / `fn serve` boot before the HTTP server could serve.
+ *
+ * After the MissionStore async migration (getMissionStoreImpl now returns the
+ * AsyncDataLayer-backed AsyncMissionStore in backend mode), the call no longer
+ * throws. The dashboard guard was updated to key off `instanceof MissionStore`:
+ * in backend mode the returned AsyncMissionStore is CRUD-only and is NOT the
+ * sync EventEmitter MissionStore that MissionAutopilot/MissionExecutionLoop are
+ * coupled to, so the guard degrades missionAutopilotImpl /
+ * missionExecutionLoopImpl to undefined. The createServer proxy objects already
+ * route through optional chaining, so undefined disables mission lifecycle
+ * features without breaking dashboard boot.
+ *
+ * This test asserts the invariant the guard relies on: a backend-mode store's
+ * getMissionStore() returns an AsyncMissionStore (not a sync MissionStore) AND
+ * isBackendMode() returns true, so the `instanceof MissionStore` guard is both
+ * necessary (without it, autopilot would be constructed against the wrong store
+ * shape) and sufficient (the ternary yields undefined rather than a crash).
+ *
+ * Note (VAL-REMOVAL-005): this test deliberately does NOT call the removed sync
+ * `new TaskStore().init()` SQLite path. It stubs `asyncLayer` to flip the store
+ * into backend mode — a pure construction-time property that does not require a
+ * live PostgreSQL connection or allocator reconciliation.

+ * PostgreSQL extension harness. The agent tools now resolve a PG-backed store
+ * via `getStore(cwd)` (injected by the harness), so worktree project-root
+ * resolution is preserved end-to-end:
+ *  - A `.worktrees/<name>` cwd is resolved by the regex in
+ *    `getProjectRootFromWorktree` back to `h.rootDir()`, where the harness
+ *    injects the shared PG store.
+ *  - A real git-linked merge worktree is resolved via
+ *    `git rev-parse --git-common-dir`; a separate repoRoot is created and the
+ *    shared PG store is injected under it with `__setCachedStoreForTesting` so
+ *    the tool resolves the SAME backend (task data is rootDir-independent in PG
+ *    mode).
+ *  - The filesystem-walk fallback (`getProjectRootFromWorktree` returns null)
+ *    is exercised from a plain project subdir.
+ *
+ * The previous SQLite-only `vi.doMock("@fusion/core")` branch asserted the
+ * "warn once when getProjectRootFromWorktree is unavailable" path. That path is
+ * unreachable under the static-import rule (the binding is always a function),
+ * so it cannot be exercised without a forbidden dynamic module reload; the
+ * fallback resolution it gated is still covered by the third case below. The
+ * FN-6430/6486/6626/6839 SQLite store-closing rescue comments are obsolete
+ * under the harness (it owns store lifecycle) and were removed.

+ * FNXC:PostgresCutover 2026-07-04-00:00:

+ *
+ * The CLI extension's agent tools resolve their store via `getStore(cwd)`, which
+ * the SQLite→PostgreSQL cutover rewired to boot the backend through
+ * `createTaskStoreForBackend`. These tests can no longer construct a legacy
+ * SQLite `new TaskStore(rootDir)` — that runtime was removed (VAL-REMOVAL-005).
+ *
+ * This harness reuses core's `createSharedPgTaskStoreTestHarness` (one isolated
+ * PG database per describe block, truncated between tests) and injects the
+ * resulting store into the extension's per-root cache via
+ * `__setCachedStoreForTesting`, so every tool call for the harness rootDir
+ * resolves to the SAME PostgreSQL-backed store the test seeds against. No
+ * embedded PostgreSQL is started in the test process — the shared external test
+ * server (localhost:5432, or FUSION_PG_TEST_URL_BASE) is used, and the whole
+ * describe is skipped when PostgreSQL is unreachable (pgDescribe contract).
+ *
+ * Assert against task state through `store().getTask(id, { includeDeleted: true })`
+ * — it returns `deletedAt` and `allowResurrection` for soft-deleted rows in
+ * backend mode, so no raw drizzle handle is needed at the CLI layer.

+ * FNXC:PostgresMigration 2026-06-26-17:00 (fix migration-review P1 #27):
+ * `fn db migrate` — the first-class cutover entry point that migrates legacy
+ * SQLite data into the configured PostgreSQL backend (embedded or external).
+ *
+ * Without this command, the first boot on the new embedded-PG default produces
+ * an EMPTY database; existing SQLite data is invisible until a hand-written
+ * script runs migrateSqliteToPostgres. This is the silent data-loss trap the
+ * migration review flagged (#27).
+ *
+ * What the command does, end to end:
+ *   1. Resolve the target PostgreSQL backend (DATABASE_URL set → external;
+ *      unset → embedded). Refuses to run if no backend is resolved.
+ *   2. Locate the legacy SQLite files (fusion.db, archive.db in the project
+ *      .fusion dir; fusion-central.db in the global ~/.fusion dir).
+ *   3. Create a pre-migration backup by COPYING the SQLite files into a
+ *      timestamped sibling directory. This is the operator safety net: if the
+ *      migration corrupts anything, the original SQLite files are intact.
+ *      (pg_dump of the PG side is not useful pre-migration because the PG side
+ *      is typically empty; the SQLite files ARE the source of truth.)
+ *   4. Open a migration Drizzle connection to the target PostgreSQL cluster.
+ *   5. Run migrateSqliteToPostgres (idempotent: ON CONFLICT DO NOTHING;
+ *      applies the schema baseline if needed; bumps identity sequences).
+ *   6. Print a per-table report (source rows, inserted rows, target rows,
+ *      verified flag) and a summary. Exits non-zero if ANY table failed
+ *      verification so CI/scripts can detect a partial migration.
+ *
+ * Usage:
+ *   fn db migrate [--dry-run] [--project <name>]
+ *
+ * --dry-run reports the planned copy (which tables, how many rows) WITHOUT
+ * modifying the PostgreSQL target. No backup is created in dry-run mode.

+/**
+ * FNXC:TestMigrationTail 2026-06-24-16:00:
+ * Reusable PostgreSQL test fixture for the SQLite→PostgreSQL migration.
+ *
+ * `createTaskStoreForTest()` is the canonical helper that test files use to
+ * obtain a PG-backed TaskStore (or any store) connected to a fresh, isolated
+ * PostgreSQL database. It eliminates the ~60 lines of boilerplate (adminExec,
+ * CREATE/DROP DATABASE, connection set, schema baseline, AsyncDataLayer) that
+ * every postgres/*.test.ts file previously duplicated.
+ *
+ * Design:
+ *   - Each call creates a uniquely-named test database (DB-per-test isolation).
+ *   - The schema baseline is applied via the schema applier.
+ *   - The returned `PgTestHarness` exposes the ready `TaskStore`, the raw
+ *     `AsyncDataLayer` (for direct row seeding), and a `teardown()` that drops
+ *     the database and closes all connections.
+ *   - When PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1), the describe
+ *     blocks that use `pgDescribe` are skipped so the merge gate stays green.
+ *
+ * Usage pattern:
+ * ```ts
+ * import { pgDescribe, createTaskStoreForTest } from "@fusion/test-utils/pg-test-harness";
+ *
+ * const pgTest = pgDescribe("my PG integration test");
+ *
+ * pgTest("creates a task and reads it back", async () => {
+ *   const h = await createTaskStoreForTest();
+ *   try {
+ *     const task = await h.store.createTask({ description: "hello" });
+ *     expect(task.id).toBeTruthy();
+ *   } finally {
+ *     await h.teardown();
+ *   }
+ * });
+ * ```
+ *
+ * The gate-safe contract: tests using this helper are auto-skipped when PG is
+ * not available, so they never break the merge gate in CI environments without
+ * PostgreSQL. Run locally with PG on 5432 to exercise the PG paths.

+ * Shared PostgreSQL test harness mirroring `createSharedTaskStoreTestHarness`
+ * from store-test-helpers.ts, but backed by PostgreSQL. This is the migration
+ * target for the ~53 core test files that today use the SQLite shared harness.
+ *
+ * Design — one PG database is created in `beforeAll` and reused across every
+ * test in the describe block. `beforeEach` resets state by:
+ *   1. TRUNCATE-ing every application table (project/central/archive schemas)
+ *      with RESTART IDENTITY CASCADE, so sequences reset and FK chains clear.
+ *   2. Resetting the singleton `config` row to DEFAULT_PROJECT_SETTINGS.
+ *   3. Clearing the TaskStore's in-memory caches so no cross-test state leaks.
+ *
+ * This is dramatically faster than `createTaskStoreForTest()` (which creates a
+ * fresh database per test) because the expensive CREATE DATABASE + schema apply
+ * happens once per file, not once per test.
+ *
+ * The harness is only usable under `pgDescribe` (auto-skipped when PG is
+ * unavailable), so it never breaks the merge gate in CI.
+ *
+ * Usage (mirrors the SQLite shared harness shape):
+ * ```ts
+ * import { pgDescribe, createSharedPgTaskStoreTestHarness } from "@fusion/test-utils/pg-test-harness";
+ *
+ * const pgTest = pgDescribe("my feature (PostgreSQL)");
+ *
+ * pgTest("does a thing", async () => {
+ *   const h = createSharedPgTaskStoreTestHarness();
+ *   await h.beforeAll();
+ *   try {
+ *     await h.beforeEach();
+ *     const store = h.store();
+ *     // ... exercise the store ...
+ *   } finally {
+ *     await h.afterEach();
+ *   }
+ * });
+ * ```
+ *
+ * For the common `describe` + `beforeAll/beforeEach/afterEach/afterAll` shape
+ * that the existing SQLite shared harness uses, the lifecycle hooks wire up
+ * directly.

+ * is an UNCAUGHT throw that exits the process — observed as `fn serve` exit(1)

+ *
+ * Surface enumeration: the buffer path has three entry points that all touched
+ * `store.db` unguarded — flushAgentLogBufferImpl (single-append flush + retry
+ * timer), appendAgentLogImpl (producer: backlog-cap warning + size/timer flush
+ * catch handlers), and appendAgentLogBatchImpl (batch append). The invariant

-/**
- * U8 (R9): entry-point half of the end-to-end single managed-PR flow.
- *
- * Composition choice (stated honestly): a single test that drives planning →
- * engine → GitHub across the dashboard↔engine↔core package boundaries is
- * impractical. So the flow is composed:
- *   - This core test proves the ENTRY-POINT contract with REAL core objects
- *     (TaskStore + MissionStore) and a real temp-dir SQLite store: mission triage
- *     stamps the real `BG-` group id into `branchContext.groupId`, members never
- *     take the shared branch as their own working branch, and
- *     `listTasksByBranchGroup(group.id)` enumerates exactly those members — which
- *     is what completion gating and PR rollup depend on.
- *   - The engine half (land on shared branch → ONE PR → sync/idempotency/abandon
- *     → safe self-heal routing) is proven with real git + real merger/coordinator
- *     in `packages/engine/src/__tests__/reliability-interactions/branch-group-single-pr-e2e.test.ts`,
- *     using a group created the same way (same sourceType/branchName shape).
- *   - The planning route entry point's group + branchContext shape is proven by
- *     the route-level planning tests; this file covers the mission entry point at
- *     the core level (where mission triage lives).
- *
- * No network and no GitHub: PR creation is the engine-side concern; here we only
- * assert the membership identity the PR flow consumes.
- *
- * ## Surface Enumeration
- * Surfaces this regression spec asserts the membership-identity invariant across:
- * - Providers / execution paths: mission triage entry point (MissionStore →
- *   TaskStore) stamping the real `BG-` group id into `branchContext.groupId`;
- *   `listTasksByBranchGroup(group.id)` membership enumeration consumed by
- *   completion gating and PR rollup. The dashboard planning-route entry point is
- *   covered by the route-level planning tests; the engine land→PR→sync→abandon
- *   half is covered by branch-group-single-pr-e2e.test.ts.
- * - Data states: members that have/have not landed (drives
- *   `isBranchGroupComplete`), and the empty-group case before triage.
- * - Shared modules/helpers reusing the logic: `branchContext.groupId`
- *   propagation, `filterTasksByBranchGroup` semantics behind
- *   `listTasksByBranchGroup`, and per-task working-branch derivation (members
- *   never adopt the shared branch as their own working branch).
- * - Breakpoints/platforms: N/A — this is a core/persistence invariant with no UI.

- *     unref'd (`Timeout#hasRef()`) immediately after `init()` schedules it —

- *  2. An end-to-end symptom test: a fixture Node process fires

-FNXC:CoreDB-LockTest 2026-06-25-21:55:
-The write-lock contention helper spawns a real child process that takes a real
-SQLite EXCLUSIVE/RESERVED lock — that real OS lock IS the thing under test, so it
-must NOT be mocked. The child releases the lock ONLY on an explicit `RELEASE`
-stdin message (signal release); there is no fixed wall-clock hold.
-
-History: a `releaseMode: "timer"` variant fired `setTimeout(release, holdMs)` in
-the child to drop the lock after a FIXED real duration (150ms per test). Two
-recovery tests used it to release the lock mid-retry, paying ~150ms of dead
-wall-clock wait each. That timer was removed: the recovery path retries via
-synchronous `sleepSync` (Atomics.wait) on the main thread, so the test cannot
-release the lock from its own event loop while blocked. Instead the test sends
-`signalRelease()` (a bare stdin write, no await) in the SAME synchronous tick
-immediately before `transactionImmediate(...)`. The parent reaches its first
-`BEGIN IMMEDIATE` before the child can schedule + read the pipe + COMMIT (a
-cross-process IPC+WAL round trip), so attempt 0 deterministically contends with
-the still-held lock; the child then commits during the parent's first
-`sleepSync` window and the retry recovers. Lock held only as long as needed,
-released deterministically, zero fixed sleeps.

- * Regression tests for the FTS5 runtime guard.
- *
- * On Node builds whose bundled SQLite lacks FTS5 (older 22.x LTS),
- * `CREATE VIRTUAL TABLE … USING fts5(…)` throws `no such module: fts5`
- * and the dashboard crashes on first-run DB migration. These tests lock in
- * the fallback path: init() must succeed, and search() must route through
- * LIKE-based SQL.
- *
- * The `FUSION_DISABLE_FTS5=1` env var forces the probe to report FTS5 as
- * unavailable even on runtimes that support it — so the CI machine can
- * exercise the same code path a fresh install on an old Node would hit.

-// U12: workflow-columns migration / integrity / graduation + rollback safety.
-//
-// Proves the U12 plan scenarios:
-//   - Migration rewrites ZERO task rows (KTD-1): fresh DB and an aged fixture DB
-//     (tasks in every legacy column, some with workflow selections) resolve every
-//     task to a valid (workflow, column) pair.
-//   - The integrity pass re-homes a task whose stored column is invalid in its
-//     resolved workflow, and is IDEMPOTENT (a second run is a no-op).
-//   - done/archived (terminal) cards are left untouched by the integrity pass.
-//   - Flag OFF after running flag-ON: legacy board + engine behavior intact.
-//   - Deliberate parity-drift injection (altered default-workflow adjacency) is
-//     CAUGHT by the graduation report's transition-parity gate.

+ *     path imposed.
+ *   - Archive DB (upsert / list / get / filterArchived / delete / rowCount /
+ *     search): the cold-storage archived-task log. Proves the jsonb comments
+ *     column and the task_json text snapshot round-trip.
+ *   - SecretsStore (create / get / list / update / reveal / delete for both
+ *     project and global scope, duplicate-key, access-policy CHECK, env
+ *     exportable): VAL-CROSS-011 (secrets encryption round-trips against the

+ * Skipped when PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1) so the merge

+ * PostgreSQL backend-mode CentralCore integration test
+ * (migrate-central-core-to-postgres).
+ *
+ * FNXC:CentralCore 2026-06-26-14:00:
+ * Integration tests proving CentralCore operates correctly in backend mode
+ * (asyncLayer injected) against real PostgreSQL. Verifies the dual-path
+ * delegation: when an AsyncDataLayer is provided, CentralCore does NOT
+ * construct a SQLite CentralDatabase, and all methods (project registry, node
+ * registry, project health, activity feed, global concurrency, mesh snapshots,
+ * project/node path mappings) round-trip through the shared connection pool.
+ *
+ * This covers the load-bearing expected behaviors:
+ *   - "CentralCore does not construct CentralDatabase when asyncLayer is provided"
+ *   - "All CentralCore methods work in backend mode via PostgreSQL"
+ *   - "Project registry, node registry, activity feed work against PG"
+ *
+ * Skipped when PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1) so the merge
+ * gate stays green without a running server.

+ * this branch (Database.init throws — SqliteFinalRemoval), so these exercise the async
+ * Drizzle helpers directly against a real PostgreSQL database:
+ *   - searchChatSessionsByMessageContent: content match, dedup to most-recent match,
+ *     wildcard escaping (%/_ literal), scope filtering, empty-query/empty-scope no-ops.
+ *   - deleteChatMessagesFrom: truncation from a target message (inclusive), retained
+ *     ordering, wrong-session/not-found no-op.
+ *   - updateChatMessageMetadata: merge (default) vs replace, missing-message error.
+ *
+ * Skipped when PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1) so the merge gate stays
+ * green without a running server. Mirrors the satellite-db-injected-stores harness.

+ *   - composeLiveSnapshot          (active sessions/runs/nodes + per-column counts)
+ *
+ * Each is exercised against an EMPTY project (proving it resolves with a

+ * seeded rows (proving the PG queries hit the real project.* tables with the

+ *
+ * FNXC:AsyncDataLayer 2026-06-24-10:00:
+ * Integration tests against a real PostgreSQL instance for the async
+ * data-layer foundation that replaces the synchronous DatabaseSync adapter.
+ * Each test creates a uniquely-named fresh database, applies the baseline
+ * migration, and exercises the transaction primitives that the migrating
+ * stores (U12-U14) will depend on.
+ *
+ * Coverage targets:
+ *   VAL-DATA-001 — async data layer has no synchronous bridge (verified by
+ *     grep in a separate static check; these tests confirm the async path works)
+ *   VAL-DATA-002 — transaction atomicity (commit): a multi-statement mutation
+ *     commits all writes together
+ *   VAL-DATA-003 — transaction atomicity (rollback): a failing mutation rolls
+ *     back all writes including the audit row
+ *   VAL-DATA-004 — concurrent transactions do not observe partial writes
+ *
+ * Also verifies:
+ *   - transactionImmediate() preserves the SQLite BEGIN IMMEDIATE atomicity
+ *     contract (multi-statement mutations commit/rollback together)
+ *   - recordRunAuditEventWithinTransaction writes the audit row inside the
+ *     shared transaction (run-audit-event-within-transaction behavior)
+ *   - the AsyncDataLayer interface compiles against the stable contract
+ *
+ * Skipped when PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1) so the merge
+ * gate stays green without a running server.

+ *
+ * FNXC:PostgresEmbedded 2026-06-24-09:10:
+ * These are real-process integration tests against the bundled embedded-postgres
+ * binary. They are gated behind FUSION_EMBEDDED_TEST_SKIP so CI / cold caches
+ * can opt out, but run by default because the embedded lifecycle is the
+ * zero-config default that must work out of the box. Each test uses a unique
+ * temp data directory so runs are hermetic.
+ *
+ * Coverage targets:
+ *   - VAL-CONN-001: first start runs initdb + ensures DB exists + serves.
+ *   - VAL-CONN-006: second start reuses the data dir without re-initdb; data persists.
+ *   - VAL-CONN-007: graceful shutdown stops the Postgres process; no orphan.

+ * Full-text search replacement (FTS5 → tsvector/GIN) PostgreSQL integration
+ * tests (fts-replacement feature, U7).
+ *
+ * FNXC:TaskStoreSearch 2026-06-24-14:00:
+ * Integration tests proving the PostgreSQL tsvector/GIN full-text search path
+ * produces correct results and sync-on-write semantics, replacing the SQLite
+ * FTS5 external-content tables (tasks_fts, archived_tasks_fts). Each test
+ * creates a uniquely-named fresh database, applies the baseline schema
+ * (which now includes the search_vector generated columns + GIN indexes), and
+ * exercises the tsvector search helpers in async-search.ts.
+ *
+ * Coverage targets (the assertions fts-replacement fulfills):
+ *   VAL-SEARCH-001 — Search parity with FTS5 baseline (row membership).
+ *   VAL-SEARCH-002 — tsvector sync-on-write (insert): new task immediately searchable.
+ *   VAL-SEARCH-003 — tsvector sync-on-write (update): text changes reflected immediately.
+ *   VAL-SEARCH-004 — tsvector sync-on-write (delete): deleted task gone from search.
+ *   VAL-SEARCH-005 — Archive search parity (row membership).
+ *   VAL-SEARCH-006 — Non-text mutation does not regenerate the tsvector.
+ *   VAL-SEARCH-007 — Index rebuild (REINDEX) restores search without data loss.
+ *
+ * Skipped when PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1) so the merge
+ * gate stays green without a running server.

+ * Mission autopilot was previously instanceof-gated OFF in PG backend mode because it

+ * and `await`s every store call (mirrors the ResearchOrchestrator union+await port), so

+ * NO real AI / scheduler / network. Slice EXECUTION (creating tasks for the next slice)
+ * is delegated to `scheduler.activateNextPendingSlice` and needs runtime providers — out
+ * of scope here — so the autopilot is constructed WITHOUT a scheduler and only its
+ * store-driven sub-operations are exercised. It asserts:
+ *   - watchMission persists autopilotState="watching" through AsyncMissionStore, and
+ *     getAutopilotStatus (now async) reflects enabled/state/watched.
+ *   - checkMissionCompletion: marking the only feature done cascades slice→milestone→

+ *     `inactive`, persisted through AsyncMissionStore, and stops watching it.

+ * PostgreSQL satellite fusion-dir stores integration test (U6).
+ *
+ * FNXC:SatelliteFusionDirStores 2026-06-24-16:00:
+ * Integration tests proving the async Drizzle helper modules for the
+ * fusion-dir-owned satellite stores (AgentStore, PluginStore, AutomationStore,
+ * RoutineStore) round-trip correctly against real PostgreSQL.
+ *
+ * VAL-DATA-015 (document/artifact parent-task scoping under soft-delete) is
+ * preserved because these stores use the same project/central schema tables
+ * and the same deletedAt-filtering invariants the task-store modules enforce;
+ * the helper round-trips here prove the jsonb/integer columns the stores depend
+ * on survive the backend swap.
+ *
+ * VAL-DATA-016 (plugin store contract stability) is directly exercised by the
+ * PluginStore section: the central.plugin_installs and
+ * central.project_plugin_states tables are the contract surface
+ * fusion-plugin-roadmap depends on.
+ *
+ * ReflectionStore is NOT covered here because it is JSONL-file based (no SQLite
+ * / PostgreSQL data path); its persistence layer does not change in this
+ * migration. It is documented in the library note.
+ *
+ * Skipped when PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1) so the merge
+ * gate stays green without a running server.

+ * PostgreSQL satellite MissionStore integration test (U6 satellite-mission-store).
+ *
+ * FNXC:MissionStore 2026-06-24-11:00:
+ * Integration tests proving the async Drizzle MissionStore helpers
+ * (async-mission-store.ts) round-trip correctly against real PostgreSQL across
+ * the full mission/milestone/slice/feature lifecycle.
+ *
+ * Coverage:
+ *   - Mission CRUD (create → get → list → update → delete) with branchStrategy
+ *     JSON serialization and autopilot columns (VAL-SCHEMA-001 parity).
+ *   - Milestone CRUD with jsonb dependencies, text acceptanceCriteria,
+ *     planningNotes/verification/validationState (the columns missing from the
+ *     initial U3 snapshot, added by this feature's schema fix).
+ *   - Slice CRUD with planState/planningNotes/verification.
+ *   - Feature CRUD with loop state machine, attempt counters, validator linkage,
+ *     generated-fix lineage columns.
+ *   - Mission events (jsonb metadata, seq ordering, count queries).
+ *   - Mission-goal links (idempotent insert, list, delete).
+ *   - Contract assertions (CRUD, reorder transactional).
+ *   - Feature-assertion links (idempotent link, unlink, list).
+ *   - Validator runs + failures + fix-feature lineage.
+ *   - Snapshot upsert (ON CONFLICT DO UPDATE) for missions/milestones/slices/
+ *     features/assertions.
+ *
+ * Skipped when PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1) so the merge
+ * gate stays green without a running server.

+/**
+ * Schema-applier + Drizzle schema parity tests (U3 / VAL-SCHEMA-001..008).
+ *
+ * FNXC:PostgresSchema 2026-06-24-04:00:
+ * Integration tests against a real PostgreSQL instance. Each test creates a
+ * uniquely-named fresh database, applies the baseline migration, and asserts
+ * the schema matches the final SQLite snapshot column-by-column and
+ * constraint-by-constraint. Skipped when PostgreSQL is unreachable so the
+ * merge gate stays green without a running server (set FUSION_PG_TEST_SKIP=1
+ * to force-skip, or FUSION_PG_TEST_URL to point elsewhere).
+ *
+ * Coverage targets:
+ *   VAL-SCHEMA-001 — fresh migration yields final-schema parity (table count
+ *     + key columns match the SQLite source of truth)
+ *   VAL-SCHEMA-002 — foreign-key cascade rules preserved (CASCADE / SET NULL)
+ *   VAL-SCHEMA-003 — unique indexes preserved
+ *   VAL-SCHEMA-004 — JSON columns are jsonb and round-trip
+ *   VAL-SCHEMA-005 — CHECK constraints preserved and enforced
+ *   VAL-SCHEMA-006 — AUTOINCREMENT maps to identity with sequence continuity
+ *   VAL-SCHEMA-007 — plugin-owned tables materialize via schema-init hook
+ *   VAL-SCHEMA-008 — three-database topology (project/central/archive schemas)

+/**
+ * PostgreSQL secrets round-trip integration test (U6 / VAL-CROSS-011).
+ *
+ * FNXC:SecretsStore 2026-06-24-12:00:
+ * Secrets must encrypt and decrypt correctly against the central PostgreSQL
+ * database. This test proves the at-rest encryption path (AES-256-GCM via
+ * createSecretCipher) round-trips through the PostgreSQL `secrets` (project
+ * schema) and `secrets_global` (central schema) `bytea` columns — the columns
+ * that the async satellite-store migration targets.
+ *
+ * Why this test exists:
+ *   The SQLite BLOB columns for `value_ciphertext` / `nonce` map to PostgreSQL
+ *   `bytea` (see schema/_shared.ts). A naive conversion could corrupt the
+ *   ciphertext/auth-tag bytes (e.g. via Buffer-vs-Uint8Array drift, hex
+ *   encoding, or truncation), which would only surface at decrypt time. This
+ *   test exercises the full encrypt → INSERT → SELECT → decrypt cycle against
+ *   both schemas so any byte-level corruption fails loudly.
+ *
+ * Coverage:
+ *   VAL-CROSS-011 — Secrets encryption round-trips against the central
+ *     PostgreSQL database (project + global scope).
+ *   VAL-DATA-016 prerequisite — the bytea-backed secret storage the plugin
+ *     store contract depends on is correct under PostgreSQL.
+ *
+ * Skipped when PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1) so the merge
+ * gate stays green without a running server.

+ *   VAL-MIGRATE-002 — idempotent re-run (no-op / clean re-sync)

+ * TaskStore lifecycle / merge-coordination PostgreSQL integration tests (U13).
+ *
+ * FNXC:TaskStoreLifecycle 2026-06-24-06:00:
+ * Integration tests proving the async lifecycle (lineage-integrity) and
+ * merge-coordination helpers preserve the load-bearing invariants against a
+ * real PostgreSQL instance. Each test creates a uniquely-named fresh database,
+ * applies the baseline schema, and exercises the async helpers that the
+ * migrating TaskStore modules consume.
+ *
+ * Coverage targets (the assertions U13 fulfills):
+ *   VAL-DATA-010 — Lineage-integrity gate blocks parent delete with live children.
+ *   VAL-DATA-011 — removeLineageReferences clears children so a parent can be deleted.
+ *   VAL-DATA-012 — Archived/soft-deleted children do not block parent delete.
+ *   VAL-DATA-013 — Handoff-to-review: column move + mergeQueue insert + audit are atomic.
+ *   VAL-DATA-014 — Merge-queue lease: priority-first, FIFO within priority,
+ *                  expired leases recover without incrementing attempts.
+ *
+ * Skipped when PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1) so the merge
+ * gate stays green without a running server.

+ * TaskStore persistence/allocator/settings PostgreSQL integration tests (U12).
+ *
+ * FNXC:TaskStorePersistence 2026-06-24-16:00:
+ * Integration tests proving the async persistence, allocator reconciliation,
+ * and settings helpers round-trip correctly against a real PostgreSQL instance.
+ * Each test creates a uniquely-named fresh database, applies the baseline
+ * schema, and exercises the async helpers that the migrating TaskStore modules
+ * consume.
+ *
+ * Coverage targets (the assertions U12 fulfills):
+ *   VAL-DATA-005 — Soft-delete visibility: live readers hide deletedAt rows.
+ *   VAL-DATA-006 — Forensic reads surface soft-deleted rows.
+ *   VAL-DATA-007 — Allocator reconciliation bumps sequences on store open.
+ *   VAL-DATA-008 — Soft-deleted/archived IDs stay reserved.
+ *   VAL-DATA-009 — Create-class inserts are non-destructive.
+ *   VAL-SCHEMA-004 — JSON columns round-trip as JSONB.
+ *
+ * Skipped when PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1) so the merge
+ * gate stays green without a running server.

+ * TaskStore remaining modules PostgreSQL integration tests (U14).
+ *
+ * FNXC:TaskStoreRemaining 2026-06-24-11:10:
+ * Integration tests proving the async archive/lineage, branch-groups,
+ * workflow-workitems, audit, comments/attachments, events, and search helpers
+ * preserve the load-bearing invariants against a real PostgreSQL instance.
+ * Each test creates a uniquely-named fresh database, applies the baseline
+ * schema, and exercises the async helpers that the migrating TaskStore
+ * modules consume.
+ *
+ * Coverage targets (the assertions U14 fulfills):
+ *   VAL-CROSS-014 — Soft-deleting a child task allows parent deletion.
+ *   VAL-CROSS-015 — Archiving a parent scopes documents/artifacts out of live
+ *     views but preserves them for restore.
+ *   Comments/attachments round-trip on active tasks.
+ *   Audit mutations and run-audit events commit or roll back together.
+ *
+ * Skipped when PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1) so the merge
+ * gate stays green without a running server.

+/**
+ * U15 engine + dashboard consumers PostgreSQL integration tests.
+ *
+ * FNXC:EngineDashboardConsumers 2026-06-24-14:30:
+ * Integration tests proving the async monitor-store and self-healing helpers
+ * (U15) preserve the monitor-stage and soft-delete-column-drift semantics
+ * against a real PostgreSQL instance. These helpers replace the direct sync
+ * `Database`/`prepare()` call sites in `packages/dashboard/src/monitor-store.ts`
+ * and `packages/engine/src/self-healing.ts`.
+ *
+ * Coverage targets:
+ *   - Dashboard monitor deployments/incidents read and write via the async path.
+ *   - The storm-guard atomic fix-task claim closes the create-then-link race
+ *     (exactly one concurrent caller wins).
+ *   - The circuit-breaker count ignores stranded sentinel placeholders.
+ *   - Engine self-healing reconcileSoftDeletedColumnDrift reconciles soft-deleted
+ *     non-archived tasks to archived, recording a per-row audit, and never moves
+ *     live tasks (FN-5147 invariant).
+ *
+ * Skipped when PostgreSQL is unreachable (FUSION_PG_TEST_SKIP=1) so the merge
+ * gate stays green without a running server.

- * - Multi-domain event correlation under a single runId
- * - Complete event shape verification
- * - Absent run context handling (backward compatibility)
- * - Partial metadata normalization
- * - Deterministic duplicate-timestamp ordering
- *
- * Run with: pnpm --filter @fusion/core exec vitest run src/run-audit.integration.test.ts

+ *   - Settings methods (getSettings, getSettingsFast, getSettingsByScope,
+ *     getSettingsByScopeFast, updateSettings) delegate to the async helpers.
+ *   - getTask reads via the async persistence helper (readTaskRow).
+ *   - listTasks reads via the async persistence helper (readLiveTaskRows).
+ *   - searchTasks delegates to the async search helpers.
+ *   - getDistributedTaskIdAllocator throws (not yet wired for full createTask).
+ *   - healthCheck returns true (async health is via /api/health).
+ *   - init() runs the async allocator reconciliation.
+ *
+ * The tests use a mock AsyncDataLayer with stubbed Drizzle queries so they

-/**
- * U4 — One-time hard-move migration of MOVED_SETTINGS_KEYS into workflow setting
- * values (R6, R8, KTD-5). The load-bearing gate is the default re-injection
- * regression: post-migration, saving an unrelated setting must NOT re-materialize
- * any moved key in raw storage.
- *
- * Strategy: the migration runs at store init. To exercise a *pre-migration
- * customized project* deterministically, we (a) init a store, (b) seed the RAW
- * `config.settings` row + global settings file with customized moved keys and
- * clear the `__meta` marker (simulating a project written by an older binary),
- * then (c) invoke the migration directly and assert the end state. This mirrors
- * the real flow (a fresh `init()` on a legacy DB) without depending on a binary
- * downgrade.

-Regression tests for in-place healing of a wedged SQLite connection.
-Incident 2026-07-10: the live dashboard's fusion.db connection went SQLITE_NOTADB
-("file is not a database" on every query) while the on-disk file stayed intact,
-and the only recovery was restarting the whole process. The adapter must reopen
-the connection in place, replay connection-scoped PRAGMAs, re-prepare cached
-statements, retry the failed operation once outside transactions, and absorb the
-unwind of a transaction that died with the old connection.
-
-The wedge is simulated by swapping the adapter's private `impl` for a stub whose
-every call throws the corruption error — exactly the observable behavior of the
-real wedged handle (the real trigger, an inconsistent pager/WAL-index view, is
-not reproducible deterministically in-process).

@@ -12,30 +12,41 @@ Original symptom: getTask throws on an unreadable PROMPT.md, 500ing all per-task
 Exact reproduction: replace a task's PROMPT.md with a directory so readFile raises EISDIR.
 Assertion it is gone: getTask resolves with the row (prompt degraded to ""), and a
 representative mutation still succeeds — the per-task API is no longer bricked.
+
+Migrated from the removed SQLite `new TaskStore(root)` path (VAL-REMOVAL-005) to the
+PostgreSQL test harness via `createTaskStoreForTest`. The harness provides a
+backend-mode TaskStore (`asyncLayer` injected) backed by an isolated PG database plus a
+real temp `rootDir` where `.fusion/tasks/{id}/PROMPT.md` lives, so the filesystem
+resilience assertions are unchanged.

-//       to a legacy column, the board stays listable, and legacy moves work.

-/**
- * U10 — End-to-end characterization of the workflow-settings hard-move (R3, R6, R7).
- *
- * This is the parity-closure suite: it proves the whole move is behavior-preserving
- * across one deterministic journey, with NO real polling and NO slow work (in-memory
- * timers are unnecessary — every step is synchronous store/resolver work; the store
- * is opened on a temp dir with a disk-backed DB so the raw `config.settings` row and
- * the global settings file survive across the seeding/migration steps, exactly as the
- * settings-migration suite does).
- *
- * The journey (single test):
- *   a. Build a PRE-migration store state: a project with customized MOVED keys
- *      (`workflowStepTimeoutMs`, `requirePrApproval`, `executionProvider`) written
- *      into the RAW `config.settings` row the way a v108-era store would hold them —
- *      BEFORE the migration runner fires (marker cleared, raw seeded). Pattern reused
- *      from settings-migration.test.ts (`seedRawProjectSettings` + `clearMarker`).
- *   b. Run the migration → assert effective values via `resolveEffectiveSettingsById`
- *      equal the customized values (engine-parity anchor).
- *   c. Edit a value via `store.updateWorkflowSettingValues` (the panel/tool write
- *      path) → assert `resolveEffectiveSettingsById` reflects it.
- *   d. Export via `exportSettings` (v2) → wipe (fresh store/project) → `importSettings`
- *      → assert identical effective values, including the `workflowSettings` section
- *      round-trip.
- *   e. Assert NO moved key exists in raw project settings at any point post-migration,
- *      and an unrelated settings save does not resurrect them.
- *
- * ── Surface-enumeration checklist (FN-5893 discipline) ────────────────────────────
- * Every surface that touches workflow settings carries at least one assertion in a
- * dedicated suite. The `surface-enumeration` describe block below asserts each of
- * these files exists (cheap meta-test) so the parity coverage cannot silently rot:
- *
- *   - engine (effective-settings):
- *       packages/engine/src/__tests__/effective-settings-merge.test.ts
- *       packages/engine/src/__tests__/effective-settings-model-lane.test.ts

+/**
+ * Async Drizzle AgentStore helpers (U6 satellite-fusiondir-stores).
+ *
+ * FNXC:AgentStore 2026-06-24-14:00:
+ * Async equivalents of the sync SQLite AgentStore call sites in
+ * agent-store.ts. AgentStore is a fusion-dir-owned satellite store: it takes a
+ * `rootDir`, constructs its own `new Database(rootDir)` internally (with a
+ * process-wide cache keyed by rootDir), and uses `db.prepare(sql).get/run/all()`
+ * + `db.transactionImmediate()` + `db.bumpLastModified()`. These helpers target
+ * the PostgreSQL project-schema tables via Drizzle and preserve the agent
+ * lifecycle, heartbeat, run, task-session, API-key, config-revision, rating,
+ * and blocked-state semantics.
+ *
+ * Tables covered (all under the `project` schema):
+ *   - `agents`                 — agent records (data + metadata stored as jsonb)
+ *   - `agent_heartbeats`       — heartbeat events (id is generated identity)
+ *   - `agent_runs`             — structured heartbeat run records (data jsonb)
+ *   - `agent_task_sessions`    — per (agentId, taskId) session data (jsonb)
+ *   - `agent_api_keys`         — API key records (data jsonb, revokedAt)
+ *   - `agent_config_revisions` — config revision history (data jsonb)
+ *   - `agent_blocked_states`   — blocked-task dedup snapshots (data jsonb)
+ *   - `agent_ratings`          — agent ratings (score CHECK 1..5)
+ *
+ * SQLite → PostgreSQL notes (VAL-SCHEMA-004):
+ *   - The `data` and `metadata` columns on `agents` (and the `data` columns on
+ *     the satellite tables) are `jsonb` in PostgreSQL, so Drizzle returns them
+ *     already-parsed as JS values. The sync store used TEXT + JSON.stringify/
+ *     parse; the helpers pass/read objects directly.
+ *   - `agent_heartbeats.id` is an identity-generated integer primary key
+ *     (AUTOINCREMENT equivalent). Inserts omit the `id` column.
+ *   - The `agent_ratings.score` column has a CHECK constraint (BETWEEN 1 AND 5)
+ *     preserved on PostgreSQL (VAL-SCHEMA-005).
+ *   - The SQLite `INSERT ... ON CONFLICT(id) DO UPDATE` upserts map directly to
+ *     Drizzle `insert().onConflictDoUpdate()`.
+ *
+ * Transition context (see library/satellite-store-migration-pattern.md):
+ *   `getDatabase()` still returns the sync `Database` until the coordinated
+ *   flip. The sync AgentStore keeps its sync path (the gate depends on it).
+ *   These helpers are the async target the PostgreSQL integration tests
+ *   consume. They program against the stable `AsyncDataLayer` interface (U4).
+ *
+ * Managed instruction bundle markdown files and run-scoped JSONL logs remain
+ * on disk (they are edited as normal project files / append-only logs) and are
+ * NOT part of this DB-layer migration.

+ * FNXC:AiSessionStore 2026-06-24-23:00:
+ * Async equivalents of the sync SQLite AiSessionStore call sites in
+ * packages/dashboard/src/ai-session-store.ts. These helpers target the
+ * PostgreSQL `project.ai_sessions` table via Drizzle, using the schema
+ * defined in schema/project.ts.
+ *
+ * The AiSessionStore persists long-running AI session state (planning, subtask
+ * breakdown, mission interview) so users can dismiss modals and return later.
+ * In backend mode (PostgreSQL), the store delegates all CRUD to these helpers
+ * via the dual-path pattern. The sync SQLite path remains for the gate suite.
+ *
+ * SQLite -> PostgreSQL notes:
+ *   - `db.prepare(sql).get/run/all()` -> awaited Drizzle queries.
+ *   - JSON columns (inputPayload, conversationHistory, result) are jsonb in
+ *     PostgreSQL, so Drizzle returns them already-parsed.
+ *   - `INSERT ... ON CONFLICT(id) DO UPDATE` upsert maps to Drizzle
+ *     `insert().onConflictDoUpdate()`.
+ *   - SQLite `changes` for detecting row existence -> Drizzle
+ *     `.returning({...})` + `.length > 0`.
+ *
+ * Transition context: these helpers live in @fusion/core (where the schema is
+ * defined) and are exported so the dashboard's AiSessionStore can import them.

+ * Async equivalents of the sync SQLite ApprovalRequestStore call sites in

+ * `project.approval_requests` and `project.approval_request_audit_events`
+ * tables via Drizzle.
+ *
+ * SQLite → PostgreSQL notes (VAL-SCHEMA-004):
+ *   The `targetContext` column is jsonb in PostgreSQL, so Drizzle returns it
+ *   already-parsed as a JS value. The audit-event insert and the status update
+ *   run in a single transaction so the audit row commits/rolls back atomically
+ *   with the state transition (matching the sync transactionImmediate pattern).
+ *
+ * Transition context (see library/satellite-store-migration-pattern.md):
+ *   `getDatabase()` still returns the sync `Database` until the coordinated
+ *   flip. These helpers are the async target the PostgreSQL integration tests
+ *   consume.

+/**
+ * Async Drizzle ArchiveDatabase helpers (U6 satellite-central-archive-db).
+ *
+ * FNXC:ArchiveDatabase 2026-06-24-19:00:
+ * Async equivalents of the sync SQLite ArchiveDatabase call sites in
+ * archive-db.ts. The archive database is the cold-storage log of archived
+ * task snapshots (`archive.archived_tasks`), append-only and queryable by
+ * archivedAt/createdAt and (in the SQLite build) FTS5. Under PostgreSQL the
+ * relational snapshot lives in the `archive` schema; the FTS5 virtual table is
+ * replaced by a tsvector/GIN index in the fts-replacement feature (U7), so
+ * this helper programs the relational table and provides an ILIKE-based
+ * search fallback that mirrors the sync `search()` LIKE path. The tsvector
+ * search path slots in here once U7 lands.
+ *
+ * SQLite → PostgreSQL notes (see library/satellite-store-migration-pattern.md):
+ *   - `db.prepare(sql).get/run/all()` → awaited Drizzle queries against
+ *     `schema.archive.archivedTasks`.
+ *   - The `comments` column is `jsonb` in PostgreSQL (VAL-SCHEMA-004), so
+ *     Drizzle returns it already-parsed. The sync store wrote it as a
+ *     TEXT-serialized `JSON.stringify(entry.comments ?? [])`; under jsonb the
+ *     value is an array. On write we pass the array directly; on read it is
+ *     already an array.
+ *   - The whole archived task is also persisted in the `task_json` text column
+ *     (a serialized ArchivedTaskEntry), matching the SQLite design where
+ *     taskJson is the canonical restore payload. `taskJson` stays TEXT in
+ *     PostgreSQL (it is a freeze-frame snapshot, not a query target), so it
+ *     is `JSON.stringify()`'d on write and `JSON.parse()`'d on read.
+ *   - The SQLite `INSERT OR REPLACE` upsert maps to Drizzle
+ *     `insert().onConflictDoUpdate()` on the primary key (id).
+ *   - FTS5-specific helpers (`rebuildFts5Index`, `optimizeFts5`,
+ *     `getFtsIndexBytes`) have no PostgreSQL equivalent in this feature —
+ *     they are reworked in U7 (tsvector/GIN). The relational CRUD and the
+ *     ILIKE search path are migrated here.
+ *
+ * Transition context (see library/satellite-store-migration-pattern.md):
+ *   `getDatabase()` still returns the sync `ArchiveDatabase` until the
+ *   coordinated `getDatabase()` flip. The sync ArchiveDatabase keeps its sync
+ *   path (the gate depends on it). These helpers are the async target the
+ *   PostgreSQL integration tests consume. They target the stable
+ *   `AsyncDataLayer` interface (U4), not the underlying driver.

+/**
+ * Async Drizzle CentralCore helpers (migrate-central-core-to-postgres).
+ *
+ * FNXC:CentralCore 2026-06-26-12:00:
+ * Async equivalents of the sync SQLite CentralCore call sites in
+ * central-core.ts. In the new single-database topology ALL central data
+ * (project registry, node registry, project health, unified activity feed,
+ * global concurrency, peer nodes, mesh shared state, managed docker nodes,
+ * settings sync, project/node path mappings) lives in the SAME embedded
+ * PostgreSQL database as the project + archive data, addressed via the
+ * `central` Drizzle schema namespace. CentralCore receives the SAME
+ * AsyncDataLayer/connection that TaskStore and the satellite stores use — NOT
+ * a separate connection. When backendMode is active, CentralCore delegates to
+ * these helpers via the shared connection pool.
+ *
+ * SQLite → PostgreSQL notes (see library/satellite-store-migration-pattern.md):
+ *   - `db.prepare(sql).get/run/all()` → awaited Drizzle queries against
+ *     `schema.central.*` table refs.
+ *   - `db.transaction(fn)` (BEGIN IMMEDIATE + SAVEPOINT nesting) →
+ *     `layer.transactionImmediate(async (tx) => ...)` (READ WRITE access mode;
+ *     PostgreSQL uses MVCC, no BEGIN IMMEDIATE). All writes inside the callback
+ *     commit atomically; a thrown error rolls back every write (VAL-DATA-002,
+ *     VAL-DATA-003).
+ *   - JSON columns (`settings`, `capabilities`, `systemMetrics`, `knownPeers`,
+ *     `versionInfo`, `pluginVersions`, `dockerConfig`, `metadata`, `payload`)
+ *     are `jsonb` in PostgreSQL, so Drizzle returns them already-parsed as JS
+ *     values. On write, pass the JS value directly. The sync store used
+ *     `toJson()`/`fromJson()` against TEXT columns; the helpers pass objects
+ *     and use `null` for absent values.
+ *   - The integer-as-boolean columns (`enabled`, `aiScanOnLoad`,
+ *     `persistentStorage`) stay integer (0/1); `row.persistentStorage === 1`
+ *     checks still work.
+ *   - `INSERT ... ON CONFLICT(...) DO UPDATE` upserts map directly to
+ *     Drizzle `insert().onConflictDoUpdate()`.
+ *   - Composite-key upserts map to `onConflictDoUpdate({ target: [...] })`.
+ *
+ * Single-database topology (architecture.md "Single-database topology"):
+ *   The central schema and the project/archive schemas share one PostgreSQL
+ *   cluster. Cross-table foreign keys (project_node_path_mappings → projects,
+ *   project_health → projects, central_activity_log → projects) reference the
+ *   central.projects table and cascade correctly.
+ *
+ * These helpers program against the stable `AsyncDataLayer` interface so the
+ * backend swap is invisible to the CentralCore contract. The sync SQLite path
+ * remains as the legacy fallback for `FUSION_NO_EMBEDDED_PG` mode.

+ * Async equivalents of the sync SQLite CentralDatabase call sites in
+ * central-db.ts. The CentralDatabase lives at `~/.fusion/fusion-central.db`
+ * and is the coordination hub for all projects: the project registry, unified
+ * activity feed, global concurrency limits, node mesh state, plugin install
+ * registry, durable mesh shared-state snapshots, offline write queue, global
+ * secrets, and the authoritative cross-node task claims table.
+ *
+ * This helper covers the load-bearing contract surface that consumers depend
+ * on: the `CentralClaimStore` interface (tryClaimTask / renewTaskClaim /
+ * releaseTaskClaim / getTaskClaim). These cross-node task claims are how the
+ * engine coordinates lease ownership when multiple nodes could race to run the
+ * same task. The remaining central tables (projects, nodes, projectHealth,
+ * centralActivityLog, globalConcurrency, centralSettings, peerNodes,
+ * settingsSyncState, managedDockerNodes, pluginInstalls, projectPluginStates,
+ * meshSharedSnapshots, meshWriteQueue, secretsGlobal) are covered by their
+ * dedicated async helpers (async-plugin-store.ts for the plugin tables; the
+ * secrets round-trip test + async-secrets-store.ts for secrets_global) or are
+ * addressable via the same schema.central.* table refs when their consumers
+ * are converted at the coordinated getDatabase() flip.
+ *
+ * SQLite → PostgreSQL notes (see library/satellite-store-migration-pattern.md):
+ *   - `db.prepare(sql).get/run/all()` → awaited Drizzle queries against
+ *     `schema.central.*` table refs.
+ *   - `db.transaction(fn)` (BEGIN IMMEDIATE + SAVEPOINT nesting) →
+ *     `layer.transactionImmediate(async (tx) => ...)` (READ WRITE access mode;
+ *     PostgreSQL uses MVCC, no BEGIN IMMEDIATE). All writes inside the callback
+ *     commit atomically; a thrown error rolls back every write (VAL-DATA-002,
+ *     VAL-DATA-003).
+ *   - The composite PRIMARY KEY (projectId, taskId) on task_claims maps
+ *     directly to the Drizzle primaryKey declaration in schema/central.ts.
+ *   - DELETE results: postgres.js does not expose rowCount; use
+ *     `.returning({...})` and check `.length`.
+ *
+ * Transition context (see library/satellite-store-migration-pattern.md):
+ *   `getDatabase()` still returns the sync `Database`/`CentralDatabase` until
+ *   the coordinated `getDatabase()` flip. The sync CentralDatabase keeps its
+ *   sync path (the gate depends on it). These helpers are the async target the
+ *   PostgreSQL integration tests consume, and the surface the engine will
+ *   program against once the connection model flips. They target the stable
+ *   `AsyncDataLayer` interface (U4), not the underlying driver.

+ *
+ * SQLite → PostgreSQL notes (VAL-SCHEMA-004):
+ *   All JSON columns (window, requestedTaskIds, evaluatedTaskIds, counts,
+ *   aggregateScores, provenance, metadata, taskSnapshot, categoryScores,
+ *   evidence, deterministicSignals, aiSignals, followUps) are jsonb in
+ *   PostgreSQL, so Drizzle returns them already-parsed as JS values. On write,
+ *   pass the JS value directly (Drizzle serializes it).
+ *
+ * Transition context (see library/satellite-store-migration-pattern.md):
+ *   `getDatabase()` still returns the sync `Database` until the coordinated
+ *   flip. These helpers are the async target the PostgreSQL integration tests
+ *   consume.

+ * Async Drizzle MissionStore helpers (U6 satellite-mission-store).
+ *
+ * FNXC:MissionStore 2026-06-24-09:00:
+ * Async equivalents of the sync SQLite MissionStore call sites in
+ * mission-store.ts (~4382 lines, 84 prepare() calls). These helpers target
+ * the PostgreSQL `project` schema tables (missions, milestones, slices,
+ * mission_features, mission_events, mission_goals, mission_contract_assertions,
+ * mission_feature_assertions, mission_validator_runs, mission_validator_failures,
+ * mission_fix_feature_lineage) via Drizzle.
+ *
+ * SQLite → PostgreSQL notes (see library/satellite-store-migration-pattern.md):
+ *   - jsonb columns (milestones.dependencies, mission_events.metadata,
+ *     mission_fix_feature_lineage.failed_assertion_ids) return already-parsed
+ *     JS values, so fromJson() is replaced by direct field access. On write,
+ *     pass the JS value directly (Drizzle serializes it).
+ *   - text columns (milestones.acceptanceCriteria, mission_features.acceptanceCriteria,
+ *     slices.planningNotes/verification, milestones.planningNotes/verification)
+ *     stay as plain strings — the U3 snapshot incorrectly mapped acceptanceCriteria
+ *     as jsonb but it is plain text (derived criteria bullet list). Fixed in this
+ *     feature's schema updates.
+ *   - boolean 0/1 integer columns (missions.autoAdvance/autoMerge/autopilotEnabled)
+ *     are kept as integer in PostgreSQL, so `row.autoAdvance === 1` checks work.
+ *   - DELETE results: postgres.js does not expose rowCount on delete. Use
+ *     .returning({ id }) and check .length (see async-todo-store.ts precedent).
+ *   - ON CONFLICT: insert().onConflictDoUpdate() for upserts (snapshot apply),
+ *     insert().onConflictDoNothing() for INSERT OR IGNORE semantics (mission_goals,
+ *     mission_events snapshot, mission_feature_assertions snapshot).
+ *   - Transactions: layer.transactionImmediate(async (tx) => ...) for multi-statement
+ *     mutations (linkGoal existence checks + insert, startValidatorRun insert + update,
+ *     deleteMilestone force-clear + delete, reorder operations).
+ *
+ * Transition context (see library/satellite-store-migration-pattern.md):
+ *   `getDatabase()` still returns the sync `Database` until the coordinated flip.
+ *   The sync MissionStore keeps its sync path (the gate depends on it). These
+ *   helpers are the async target the PostgreSQL integration tests consume and
+ *   that the MissionStore facade will delegate to after the getDatabase() flip.
+ *   They program against the stable `AsyncDataLayer` interface (U4), not the

+// PostgreSQL-backed MissionStore — the AsyncDataLayer counterpart of the sync
+// SQLite `MissionStore` (mission-store.ts). Exposes the SAME public method names
+// the dashboard mission routes + goal→mission routes + CLI mission tools call,
+// so callers `await` either implementation. `getMissionStoreImpl` returns this in
+// backend mode instead of throwing "MissionStore is not available in PG backend
+// mode". Id/timestamp generation mirrors the sync store (M-/MS-/SL-/F-/ME-/CA-/VR-
+// prefixes via generateId), as do the status-rollup recompute cascades
+// (feature→slice→milestone→mission) and the milestone validation-state recompute.
+//
+// Known gap vs the sync store: the sync MissionStore is an EventEmitter
+// (mission:created/feature:linked/validator-run:completed/…) consumed by the
+// engine MissionAutopilot + dashboard SSE. This wrapper performs CRUD + rollups +
+// triage only; mission AUTOPILOT and live SSE mission events stay degraded in PG
+// mode (the engine guards init with `instanceof MissionStore`). The engine-only
+// loop helpers (completeValidatorRun/recordValidatorFailures/reapValidatorRun/
+// createGeneratedFixFeature/transitionLoopState/getMissionHierarchySnapshot/
+// applyMissionHierarchySnapshot/listGoalIdsForTask) are NOT ported here — their
+// sync consumers are instanceof-guarded.

+/**
+ * FNXC:MissionStore 2026-06-28-13:00:
+ * SSE live-push parity — AsyncMissionStore extends EventEmitter<MissionStoreEvents>
+ * and emits the SAME events at the SAME mutation points as the sync MissionStore
+ * (mission-store.ts) so the dashboard SSE handler live-refreshes mission/milestone/
+ * slice/feature/assertion changes in PG backend mode (previously only manual reload
+ * updated them). Emit sites are mirrored method-by-method from the sync store's
+ * `this.emit(` call sites; each emit fires AFTER the persistence await succeeds with
+ * the same payload (the persisted entity) the sync store emits. The status-cascade
+ * recompute helpers (recomputeSliceStatus/MilestoneStatus/MissionStatus/MilestoneValidation)
+ * route through the emitting update* methods, so cascade-driven updates emit exactly as
+ * in the sync store. The instance is cached on the TaskStore, so SSE subscribes to the
+ * same object the mission routes mutate.
+ *
+ * Known gap vs the sync store: completeValidatorRun / reapValidatorRun /
+ * createGeneratedFixFeature (validator-run:completed, fix-feature:created) are not ported
+ * into the async wrapper, so those two events never fire in PG mode (validator-run loop
+ * execution stays a sync-mode capability).

+/**
+ * Async Drizzle PluginStore helpers (U6 satellite-fusiondir-stores).
+ *
+ * FNXC:PluginStore 2026-06-24-13:00:
+ * Async equivalents of the sync SQLite PluginStore call sites in
+ * plugin-store.ts. PluginStore is a fusion-dir-owned satellite store with a
+ * dual-scope persistence model: global install metadata lives in the central
+ * database (`central.plugin_installs`) while per-project enablement/runtime
+ * state lives in the central database (`central.project_plugin_states`). The
+ * sync store opens both a local `Database(rootDir/.fusion)` (now only for the
+ * legacy migration marker) and a `CentralDatabase`. Under the shared PostgreSQL
+ * backend both scopes are served by the same connection set, so these helpers
+ * take a single `AsyncDataLayer` and address the central-schema tables via
+ * `schema.central.*`.
+ *
+ * VAL-DATA-016 (plugin store contract stability) is the load-bearing
+ * constraint for this store: the `fusion-plugin-roadmap` plugin consumes the
+ * store layer and must keep working. The async helpers program against the
+ * stable `AsyncDataLayer` interface so the backend swap is invisible to the
+ * plugin contract.
+ *
+ * SQLite → PostgreSQL notes (VAL-SCHEMA-004):
+ *   - The `settings`, `settingsSchema`, `dependencies`, and `lastSecurityScan`
+ *     columns are `jsonb` in PostgreSQL, so Drizzle returns them already-parsed
+ *     as JS values. On write, pass the JS value directly. The sync store used
+ *     `toJson()`/`fromJson()` against TEXT columns; the helpers pass objects.
+ *     Note: `lastSecurityScan` is a `text` column in the PostgreSQL central
+ *     schema (stores serialized JSON), so it must be `JSON.stringify()`'d on
+ *     write and `JSON.parse()`'d on read to match the sync behavior.
+ *   - The boolean `enabled` and `aiScanOnLoad` columns are kept as integer
+ *     (0/1), so `row.enabled === 1` checks still work.
+ *   - The `INSERT ... ON CONFLICT(id) DO UPDATE` upsert maps directly to
+ *     Drizzle `insert().onConflictDoUpdate()`.
+ *   - The composite-key upsert on `project_plugin_states`
+ *     (projectPath, pluginId) maps to `onConflictDoUpdate({ target: [projectPath, pluginId] })`.
+ *
+ * Transition context (see library/satellite-store-migration-pattern.md):
+ *   `getDatabase()` still returns the sync `Database` until the coordinated
+ *   flip. The sync PluginStore keeps its sync path (the gate depends on it).
+ *   These helpers are the async target the PostgreSQL integration tests
+ *   consume.

+ * (research-store.ts) so the dashboard SSE handler live-refreshes in PG backend mode
+ * instead of only on manual reload. Emit sites are mirrored method-by-method from the
+ * sync store's `this.emit(` call sites: createRun→run:created, updateRun→run:updated,
+ * deleteRun→run:deleted, addEvent→event:added, addSource→source:added, updateStatus→
+ * run:status_changed (+run:completed/failed/cancelled/timed_out). Each emit fires AFTER

+ * store emits. The instance is cached on the TaskStore, so SSE subscribes to the same
+ * object the routes mutate.
+ *
+ * Known gap vs the sync store: AI research EXECUTION (orchestrator dispatch) stays
+ * degraded in PG mode — the dashboard CRUD/lifecycle surface is in scope. requestCancellation/
+ * createRetryRun mirror the sync helpers (which emit only indirectly via the sync
+ * updateRun/updateStatus); the async variants call the helpers directly, so their

+ * Async Drizzle RoutineStore helpers (U6 satellite-fusiondir-stores).
+ *
+ * FNXC:RoutineStore 2026-06-24-12:30:
+ * Async equivalents of the sync SQLite RoutineStore call sites in
+ * routine-store.ts. RoutineStore is a fusion-dir-owned satellite store: it
+ * takes a `rootDir`, constructs its own `new Database(rootDir/.fusion)`
+ * internally, and uses `db.prepare(sql).get/run/all()` + `db.bumpLastModified()`.
+ * These helpers target the PostgreSQL `project.routines` table via Drizzle and
+ * preserve the create/read/update/delete, run-tracking, and due-query semantics.
+ *
+ * SQLite → PostgreSQL notes (VAL-SCHEMA-004):
+ *   - The boolean `enabled` column is kept as integer (0/1) in PostgreSQL, so
+ *     `row.enabled === 1` checks still work.
+ *   - The `triggerConfig`, `steps`, `lastRunResult`, and `runHistory` columns
+ *     are `jsonb` in PostgreSQL, so Drizzle returns them already-parsed as JS
+ *     values. On write, pass the JS value directly. The sync store
+ *     JSON.stringified triggerConfig into a TEXT column; the PostgreSQL schema
+ *     stores it as jsonb, so the helper passes the object directly.
+ *   - The SQLite `INSERT OR REPLACE` upsert maps to Drizzle
+ *     `insert().onConflictDoUpdate()` on the primary key.
+ *
+ * Transition context (see library/satellite-store-migration-pattern.md):
+ *   `getDatabase()` still returns the sync `Database` until the coordinated
+ *   flip. The sync RoutineStore keeps its sync path (the gate depends on it).
+ *   These helpers are the async target the PostgreSQL integration tests
+ *   consume.

+/**
+ * Async Drizzle SecretsStore helpers (U6 satellite-central-archive-db).
+ *
+ * FNXC:SecretsStore 2026-06-24-20:00:
+ * Async equivalents of the sync SQLite SecretsStore call sites in
+ * secrets-store.ts. SecretsStore is dual-scope: it writes project-scoped
+ * secrets to `project.secrets` and global-scoped secrets to
+ * `central.secrets_global`. Under the shared PostgreSQL backend both scopes
+ * are served by the single `AsyncDataLayer` (the connection serves all
+ * schemas), so the dual-database injection (projectDb + centralDb) collapses
+ * to one layer and the scope selects the table.
+ *
+ * This is the "SecretsStore async injection against central PostgreSQL" the
+ * feature requires. The sync store keeps its sync path until the coordinated
+ * `getDatabase()` flip (the gate depends on it); these helpers are the async
+ * target the PostgreSQL integration tests consume and the surface the
+ * dashboard/engine will program against once the connection model flips.
+ *
+ * SQLite → PostgreSQL notes (see library/satellite-store-migration-pattern.md
+ * and library/satellite-fusiondir-stores-notes.md):
+ *   - The BLOB `value_ciphertext` / `nonce` columns are `bytea` in PostgreSQL
+ *     (VAL-SCHEMA-004 / VAL-CROSS-011). The secrets-roundtrip test proves the
+ *     bytes survive byte-identical; the cipher is driver-agnostic.
+ *   - The boolean `env_exportable` integer 0/1 column is kept as integer in
+ *     PostgreSQL ("kept as integer to preserve exact behavior"), so
+ *     `row.envExportable === 1` checks still work.
+ *   - SQLite `UNIQUE constraint failed` → PostgreSQL unique_violation
+ *     (error code 23505). The code may be on the error directly (raw
+ *     postgres.js) or on the `cause` (Drizzle wraps postgres errors).
+ *   - `db.bumpLastModified()` (an in-memory change-notification timestamp) has
+ *     no PostgreSQL equivalent at this layer; change notification moves to
+ *     LISTEN/NOTIFY at the consumer layer. It is a no-op on the async path.
+ *
+ * Transition context:
+ *   The sync SecretsStore constructor takes `projectDb` + `centralDb` (both the
+ *   sync `Database`/`CentralDatabase`). The async target takes the single
+ *   `AsyncDataLayer` plus a `MasterKeyProvider`. The helpers below are the
+ *   async data path; a thin async wrapper class (`AsyncSecretsStore`) wires
+ *   them together with the cipher and the audit emitter so consumers can drop
+ *   it in place of the sync store at the flip.

+ * Async Drizzle TodoStore helpers (U6 satellite-db-injected-stores).
+ *
+ * FNXC:TodoStore 2026-06-24-06:00:
+ * Async equivalents of the sync SQLite TodoStore call sites in todo-store.ts.
+ * These helpers target the PostgreSQL `project.todo_lists` and
+ * `project.todo_items` tables via Drizzle and preserve the list/item CRUD
+ * round-trip, ordering, and toggle semantics.
+ *
+ * SQLite → PostgreSQL notes (VAL-SCHEMA-004):
+ *   The boolean `completed` column is kept as integer (0/1) in PostgreSQL
+ *   (per _shared.ts: "kept as integer to preserve exact behavior"), so
+ *   `row.completed === 1` checks still work. There are no JSON columns on
+ *   these tables.
+ *
+ * Transition context (see library/satellite-store-migration-pattern.md):
+ *   `getDatabase()` still returns the sync `Database` until the coordinated
+ *   `getDatabase()` flip. The sync TodoStore keeps its sync path (the gate
+ *   depends on it). These helpers are the async target the PostgreSQL
+ *   integration tests consume. They program against the stable
+ *   `AsyncDataLayer` interface (U4), not the underlying driver.

+ * FNXC:SqliteFinalRemoval 2026-06-26-09:45:
+ * SQLite CentralDatabase class body DELETED (VAL-REMOVAL-005).
  *
- * Uses Node.js built-in `node:sqlite` (DatabaseSync) for simplified
- * synchronous transaction handling. The database runs in WAL mode
- * for concurrent reader/writer access.
+ * The ~1090-line legacy sync `CentralDatabase` class (central schema SQL, 13
+ * migrations, PRAGMA busy_timeout/journal_mode=DELETE/synchronous=foreign_keys,
+ * BEGIN IMMEDIATE + SAVEPOINT nested transactions, task-claim mutex) was the
+ * central-project-registry data layer. The runtime CentralCore now delegates
+ * ALL central data access to PostgreSQL via the async `AsyncDataLayer`
+ * (Drizzle, central schema) — see `async-central-core.ts`. The SQLite path is
+ * only reachable in non-backend mode (FUSION_NO_EMBEDDED_PG test/migrator
+ * fallback), and the mesh lease recovery path that constructed it in
+ * `in-process-runtime.ts` now skips construction in backend mode.
  *
- * This database is stored at `~/.fusion/fusion-central.db` and serves as the
- * coordination hub for all projects, storing the project registry,
- * unified activity feed, global concurrency limits, and project health.
+ * This module now re-exports the JSON utilities and `getDefaultCentralDbPath`
+ * (still used by backup.ts and the onboard CLI), and provides a stub
+ * `CentralDatabase` class whose methods throw. The stub preserves the public
+ * type shape (including the `CentralClaimStore` interface) so consumers
+ * continue to type-check under `tsc --noEmit` while the SQLite runtime is
+ * removed.

 /**
- * SQLite database module for fn task board storage.
+ * FNXC:SqliteFinalRemoval 2026-06-26-09:30:
+ * SQLite Database class body DELETED (VAL-REMOVAL-005).
  *
- * Uses Node.js built-in `node:sqlite` (DatabaseSync) for simplified
- * synchronous transaction handling. The database runs in WAL mode
- * for concurrent reader/writer access.
+ * The full ~5900-line SQLite `Database` class (schema SQL, 130 migrations,
+ * PRAGMA configuration, FTS5 virtual tables/triggers, VACUUM/WAL-checkpoint
+ * maintenance, integrity-check offload, schema-compat fingerprinting) was the
+ * legacy synchronous data layer. The runtime now uses PostgreSQL via the
+ * async `AsyncDataLayer` (Drizzle) for ALL production data access. The SQLite
+ * path was only reachable in non-backend mode (test fixtures / one-time
+ * migrator), and the migrator uses the low-level `DatabaseSync` from
+ * `sqlite-adapter.ts` directly — it never needed this class.
  *
- * Schema version tracking is managed via a `__meta` table.
+ * This module now re-exports the pure JSON/schema utilities that ~55 production
+ * files import (extracted to `db-helpers.ts`) and provides a stub `Database`
+ * class whose methods throw. The stub preserves the public type shape so the
+ * satellite stores' sync else-branches (dead in backend mode) and the
+ * quarantined test files continue to type-check under `tsc --noEmit` while
+ * their SQLite runtime code is removed in lockstep.
+ *
+ * What is KEPT for the one-time SQLite→PostgreSQL migration tool:
+ *   - `sqlite-adapter.ts` (`DatabaseSync`)
+ *   - `sqlite-validation.ts`
+ *   - `sqlite-migrator.ts` (migration tool; lives in the migrator package)
+ *
+ * What is GONE: every PRAGMA, ATTACH DATABASE, FTS5 probe, VACUUM, WAL
+ * checkpoint, integrity_check, and `sqlite3` CLI offload code path.

--- Command Center tool analytics (aggregateToolAnalytics in tool-analytics.ts) filters usage_events by 'kind' (e.g. 'tool_call', 'session_start') with optional 'ts' bounds on every tool/session count. The (kind, ts) composite index keeps that path from scanning unrelated event kinds as telemetry grows. Added in the same unreleased PR (#1683) that introduces usage_events, so it ships inside migration 118 rather than a new version bump; mirrored there so fresh-init and migrated DBs converge.

- * not be pinned alive by this child's stdio pipes. Unref the child (+ stdio)
- * immediately after spawn via the shared `unrefQmdChildProcess` helper — see its

- * Test-only migrated-schema snapshot. db.init() replays the full schema plus
- * ~129 migrations on every fresh in-memory DB (~30-90ms each), which is minutes
- * of pure setup across thousands of DB-backed tests. The snapshot harness
- * (store-test-helpers.ts → installInMemoryDbSnapshot) builds ONE migrated
- * in-memory DB per test file, serializes it, and registers the bytes here.
- * Any subsequent in-memory Database deserializes the snapshot at open time, so
- * init() finds schemaVersion === SCHEMA_VERSION and the matching compat
- * fingerprint and short-circuits all migration/backfill work. Each test still
- * gets a brand-new, fully-isolated in-memory DB — only the migration cost is
- * amortized. Never consulted for disk-backed (production) databases.
+ * Stub `Database` class.
+ *
+ * FNXC:SqliteFinalRemoval 2026-06-26-09:30:
+ * The ~5900-line SQLite `Database` class body (constructor, schema SQL, 130
+ * migrations, PRAGMA/FTS5/VACUUM/WAL/integrity-check code) is DELETED. This
+ * stub preserves the public method signatures so the satellite stores' sync
+ * else-branches and quarantined test files continue to type-check under
+ * `tsc --noEmit`. Every method throws because the SQLite runtime is gone;
+ * production runs in backend mode (PostgreSQL) and never reaches these.

+/**
+ * Async data-layer foundation (U4) — replaces the synchronous DatabaseSync adapter.
+ *
+ * FNXC:AsyncDataLayer 2026-06-24-09:00:
+ * The synchronous `DatabaseSync` surface (`db.prepare(sql).get/run/all`,
+ * `db.transaction(fn)`, `db.transactionImmediate(fn)`) is replaced by an async
+ * Drizzle-backed connection. This module defines the stable data-layer
+ * interface (the "AsyncDataLayer") that plugin stores and the decomposed
+ * task-store modules consume, and provides the core CRUD/transaction
+ * primitives they depend on.
+ *
+ * Why this module exists:
+ *   R6 — the sync DatabaseSync data-access surface is replaced with an async
+ *   data layer; no blocking/synchronous bridge to PostgreSQL remains
+ *   (VAL-DATA-001). Every PostgreSQL client is async, so every data call site
+ *   must be awaited. Store methods are already `async`, so the boundary exists;
+ *   this module is the inner layer they call into.
+ *
+ * What this module provides (the foundation; U12-U15 migrate the actual stores):
+ *   1. `AsyncDataLayer` — the stable interface plugin stores consume. It exposes
+ *      the runtime Drizzle instance, a `transaction()` primitive, and
+ *      `transactionImmediate()` for write-heavy paths.
+ *   2. `transactionImmediate(async (tx) => ...)` — the async equivalent of the
+ *      SQLite `BEGIN IMMEDIATE` path. In SQLite this acquired the RESERVED lock
+ *      before user code ran so writers fail/retry before the callback executes.
+ *      PostgreSQL uses MVCC (no BEGIN IMMEDIATE), so the closest equivalent for
+ *      write-heavy paths is a transaction with READ WRITE access mode. All
+ *      writes inside the callback commit atomically; a thrown error rolls back
+ *      every write including audit rows (VAL-DATA-002, VAL-DATA-003).
+ *   3. `recordRunAuditEventWithinTransaction(tx, input)` — the run-audit-event
+ *      insertion that runs *inside* a shared transaction so the audit row
+ *      commits or rolls back atomically with the mutation it accompanies
+ *      (the run-audit-event-within-transaction behavior).
+ *   4. The `getDatabase()` accessor contract changes to return this async-capable
+ *      connection rather than the synchronous `Database` (U15 converts the
+ *      direct-`prepare()` consumers that relied on the sync shape).
+ *
+ * Transaction isolation (VAL-DATA-004):
+ *   Concurrent transactions do not observe each other's uncommitted writes.
+ *   PostgreSQL's default `READ COMMITTED` isolation already guarantees this —
+ *   a transaction never sees another transaction's uncommitted rows.
+ *   `transactionImmediate()` defaults to `READ COMMITTED` (matching the SQLite
+ *   behavioral contract: SQLite's default is also a read-committed-equivalent
+ *   under WAL). Callers needing stricter guarantees can pass an isolation level.
+ *
+ * Concurrency model change:
+ *   SQLite used WAL multi-process-over-one-file with BEGIN IMMEDIATE for
+ *   write serialization. PostgreSQL uses a server process with MVCC, which
+ *   structurally removes single-writer contention. The atomicity contract
+ *   (multi-statement mutations commit/rollback together) is preserved by the
+ *   Drizzle transaction callback wrapper.

+ * Embedded PostgreSQL lifecycle manager (U2).
+ *
+ * FNXC:PostgresEmbedded 2026-06-24-09:05:
+ * Manages a bundled embedded PostgreSQL process over a local data directory so
+ * the full Fusion package works with zero system Postgres install when
+ * DATABASE_URL is unset (the zero-config default, mirroring SQLite today).
+ *
+ * Lifecycle:
+ *   1. `start()` — allocates a free port (if none configured), runs `initdb`
+ *      ONLY when the data directory is not yet initialized (PG_VERSION absent),
+ *      starts the postgres process, and ensures the application database
+ *      exists (idempotent). Returns a `ResolvedBackend` (embedded mode) with the
+ *      connection URL so the connection layer (U1) can build the Drizzle pool.
+ *   2. `stop()` — stops the postgres process via SIGINT (pg_ctl semantics) so
+ *      no orphaned process remains (VAL-CONN-007).
+ *   3. A process-exit shutdown hook is registered automatically so SIGTERM /
+ *      SIGINT cleanly stop the embedded process even if the caller forgets.
+ *
+ * Idempotency notes (critical for VAL-CONN-006 — data persists across restarts):
+ *   - `embedded-postgres`'s `.initialise()` ALWAYS runs `initdb`, which FAILS if
+ *     the data directory already exists ("directory exists but is not empty").
+ *     This manager guards `initialise()` behind a `PG_VERSION` existence check so
+ *     a second start reuses the existing cluster without re-initializing.
+ *   - `embedded-postgres`'s `.createDatabase()` issues a raw `CREATE DATABASE`
+ *     which errors if the DB exists. This manager queries `pg_database` first and
+ *     only creates when missing, so re-starts are safe.
+ *
+ * Credential safety:
+ *   - The connection URL contains the password (needed to connect). It is never
+ *     logged; `getRedactedConnectionUrl()` provides a log-safe variant.
+ *   - The `onLog`/`onError` callbacks are the only logging surfaces; callers
+ *     must not embed credentials in log messages.

+-- snapshot of the final SQLite schema (SCHEMA_VERSION=128) translated to
+-- PostgreSQL. The 128 hand-rolled SQLite migrations are NOT reimplemented;
+-- this file materializes their final result.
+--
+-- Three-database topology (VAL-SCHEMA-008): project/central/archive are three
+-- distinct PostgreSQL schemas in one cluster, mirroring the three SQLite files
+-- (fusion.db / fusion-central.db / archive.db).
+--
+-- Type mapping (binding):
+--   INTEGER PRIMARY KEY AUTOINCREMENT → integer GENERATED ALWAYS AS IDENTITY
+--     (sequence continuity: VAL-SCHEMA-006)
+--   JSON-encoded TEXT → jsonb (round-trip shape parity: VAL-SCHEMA-004)
+--   BLOB → bytea (secrets ciphertext/nonce)
+--   INTEGER 0/1 flags → integer (preserved verbatim, no boolean coercion)
+--   TEXT timestamps → text (ISO-8601 strings preserved)
+--   REAL → real
+--
+-- CHECK constraints, FK cascade rules, and unique indexes preserved one-for-one
+-- (VAL-SCHEMA-002, VAL-SCHEMA-003, VAL-SCHEMA-005).
+--
+-- FTS5 tables (tasks_fts, archived_tasks_fts) are replaced by tsvector/GIN
+-- generated columns (search_vector) on the tasks and archived_tasks tables

+/**
+ * PostgreSQL backup and restore via pg_dump / pg_restore.
+ *
+ * FNXC:PostgresBackup 2026-06-24-21:00:
+ * After the SQLite→PostgreSQL cutover, backups are PostgreSQL logical dumps
+ * (`pg_dump`) instead of SQLite file copies. This module reworks the
+ * `BackupManager` contract for PostgreSQL: it produces restorable dumps and
+ * restores them via `pg_restore`, preserving the project + central pairing
+ * that the SQLite BackupManager maintained (VAL-REMOVAL-003).
+ *
+ * The three Fusion databases (project, central, archive) are PostgreSQL
+ * schemas within a single cluster. A backup therefore dumps the application
+ * schemas (not the whole cluster, which may contain unrelated databases).
+ * The project + central pair is preserved as two timestamped dump files in
+ * the same backup directory, mirroring the SQLite `fusion-*.db` +
+ * `fusion-central-*.db` pairing.
+ *
+ * The dump format is `--format=custom` (pg_dump's native compressed format)
+ * because it supports parallel restore, selective restore, and is restorable
+ * via `pg_restore`. This is the standard PostgreSQL backup format.
+ *
+ * FNXC:PostgresBackup 2026-06-26-15:00 (fix migration-review P0 #5/#6):
+ * Security: the connection components (host/port/user/password/dbname) are
+ * passed to pg_dump/pg_restore via the libpq environment variables
+ * (PGHOST/PGPORT/PGUSER/PGPASSWORD/PGDATABASE), not as CLI arguments, so the
+ * password never appears in the process argument list (visible via `ps`). The
+ * PREVIOUS implementation used `PG_CONNECTION_STRING`, which is NOT a libpq
+ * variable — pg_dump/pg_restore ignored it and fell back to the libpq defaults
+ * (localhost:5432, current OS user). In embedded mode (random high port) the
+ * dump/restore silently targeted the wrong server (an empty system default DB
+ * or no server at all). Parsing the URL into the real PG* variables fixes both
+ * the embedded-mode correctness and the credential-safety contract.

+/**
+ * SQLite-to-PostgreSQL data migration tool (U9 / VAL-MIGRATE-001..006).
+ *
+ * FNXC:PostgresMigration 2026-06-24-08:00:
+ * Snapshots the current final SQLite schema into PostgreSQL and bulk-copies
+ * all data across the three Fusion databases (project/central/archive),
+ * idempotently and with verification. This is the cutover migration tool: it
+ * takes a populated set of SQLite files (fusion.db, fusion-central.db,
+ * archive.db) and lands their contents into the PostgreSQL schemas
+ * (project/central/archive) so the application can switch its read/write path
+ * to PostgreSQL.
+ *
+ * What the tool does, end to end:
+ *   1. Applies the fresh PostgreSQL schema baseline (via applySchemaBaseline)
+ *      so the target tables exist. The baseline is idempotent; re-running is
+ *      safe.
+ *   2. For each of the three source SQLite databases, enumerates the user
+ *      tables and introspects each table's columns from both SQLite
+ *      (PRAGMA table_info, camelCase names) and PostgreSQL
+ *      (information_schema + pg_attribute, snake_case names). The two column
+ *      sets are matched by a verified camelCase→snake_case transformation, so
+ *      the tool is schema-driven rather than hand-coded per-table.
+ *   3. Streams rows from SQLite and batches INSERTs into PostgreSQL with
+ *      type-aware value conversion:
+ *        - SQLite TEXT holding JSON  → PostgreSQL jsonb (parsed)
+ *        - SQLite BLOB               → PostgreSQL bytea (Buffer)
+ *        - identity columns          → omitted from INSERT (let the sequence
+ *          assign), then the sequence is bumped to max(id)+1 afterwards so new
+ *          inserts do not collide (VAL-MIGRATE-004).
+ *        - GENERATED ALWAYS columns  → omitted from INSERT (auto-populated).
+ *   4. Uses INSERT ... ON CONFLICT DO NOTHING for idempotency on the primary
+ *      key, so re-running against an already-migrated database is a clean
+ *      re-sync / no-op (VAL-MIGRATE-002).
+ *   5. Verifies per-table row counts (SQLite vs PostgreSQL) after the copy
+ *      (VAL-MIGRATE-001).
+ *
+ * Dry-run mode (VAL-MIGRATE-005): reports the planned copy (which tables, how
+ * many rows, the column mapping) WITHOUT modifying the PostgreSQL target.
+ *
+ * Soft-delete/deletedAt handling: rows are copied verbatim, including
+ * soft-deleted rows (deletedAt IS NOT NULL). The soft-delete visibility
+ * invariant is a query-time filter, not a copy-time filter — migrating the
+ * rows preserves the forensic/restore surface (VAL-DATA-006).
+ *
+ * JSON column fidelity (VAL-MIGRATE-003): text-JSON is parsed to a JS value
+ * and re-inserted into the jsonb column, so objects/arrays/nested values/null
+ * round-trip with identical shape. The jsonb type detection is driven by the
+ * materialized PostgreSQL column type (information_schema.data_type = 'jsonb').
+ *
+ * AUTOINCREMENT sequence continuity (VAL-MIGRATE-004): every PostgreSQL
+ * identity sequence is bumped to max(id)+1 after the copy so new inserts do
+ * not collide with migrated rows.

+/**
+ * Runtime startup factory: construct a PostgreSQL-backed TaskStore.
+ *
+ * FNXC:RuntimeStartupWiring 2026-06-26-14:00:
+ * This is the single startup entry point that production construction sites
+ * (engine InProcessRuntime, dashboard project-store-resolver, CLI serve/
+ * dashboard commands, desktop local-server/local-runtime) consult to decide
+ * whether to boot against PostgreSQL or fall back to the legacy SQLite path.
+ *
+ * The factory encapsulates the five-step backend boot sequence so individual
+ * call sites do not each re-implement backend resolution, connection opening,
+ * schema application, AsyncDataLayer construction, and dual-read harness
+ * integration. A call site asks: "given the current environment, do I get a
+ * PostgreSQL-backed TaskStore, or do I keep the SQLite default?" The factory
+ * answers with either a ready {@link BackendBootResult} or `null` (meaning:
+ * use the legacy SQLite construction — byte-identical to the pre-migration
+ * path).
+ *
+ * Resolution rules (matching the mission architecture):
+ *   - DATABASE_URL set (external mode): connect to the external PostgreSQL
+ *     server, apply the schema baseline, construct the AsyncDataLayer. Returns
+ *     a backend boot result.
+ *   - DATABASE_URL unset (embedded mode): start the bundled embedded
+ *     PostgreSQL, then proceed like external mode against the embedded URL.
+ *     This is the DEFAULT production path — embedded PG is the zero-config
+ *     backend, mirroring the zero-config SQLite experience it replaces.
+ *   - DATABASE_URL unset AND FUSION_NO_EMBEDDED_PG=1: return `null`. The caller
+ *     constructs the legacy SQLite-backed TaskStore. This is the explicit
+ *     opt-out for the legacy SQLite path, available for backward compatibility
+ *     during the cutover window.
+ *
+ * FNXC:BackendFlip 2026-06-26-14:05:
+ * The default backend was flipped from SQLite to embedded PostgreSQL in this
+ * change (feature flip-embedded-pg-default, cutover milestone). Previously
+ * embedded PG required an explicit opt-in via FUSION_EMBEDDED_PG=1; now it is
+ * the default and FUSION_NO_EMBEDDED_PG=1 is the opt-out back to legacy
+ * SQLite. FUSION_EMBEDDED_PG=1 is still honored as a no-op alias for backward
+ * compatibility (it cannot force embedded when DATABASE_URL is set, since
+ * external mode always wins). The flip is safe because the embedded-postgres
+ * platform binaries are now bundled for macOS/Linux/Windows (arm64/x64) and
+ * the boot smoke has been updated to exercise the embedded path by default
+ * with an initdb-aware health-check timeout. Tests that need the fast SQLite
+ * default (no initdb, no binary) set FUSION_NO_EMBEDDED_PG=1 explicitly.

-FNXC:SqliteConnectionReopen 2026-07-10-22:50:
-A long-lived connection can wedge in-process: SQLite's pager/WAL-index view goes
-inconsistent (observed 2026-07-10 during checkpoint activity on the 293MB WAL-mode
-fusion.db), one query fails "database disk image is malformed", and every query
-after that returns SQLITE_NOTADB ("file is not a database") forever — while the
-on-disk file stays fully intact. Before this fix the only recovery was restarting
-the whole dashboard/engine process, because all corruption-recovery machinery runs
-at connection-OPEN time only.
-
-The adapter now heals in place: on a connection-corruption error it closes the dead
-handle, opens a fresh one on the same path, replays recorded assignment-style
-PRAGMAs (connection-scoped settings like busy_timeout/foreign_keys/synchronous),
-verifies the file with PRAGMA quick_check, and retries the failed operation once.
-Statements returned by prepare() are generation-tracked so ones created before the
-reopen transparently re-prepare on the new connection.
-
-Safety rules:
-- Retry only outside an explicit transaction. A statement inside a broken
-  transaction must NOT be retried on the fresh connection (it would commit as an
-  orphan autocommit write); the connection is still healed but the original error
-  is rethrown so the caller's transaction fails loudly.
-- After a mid-transaction reopen, the caller's unwind statements
-  (ROLLBACK/ROLLBACK TO/RELEASE/COMMIT) are absorbed as no-ops — the fresh
-  connection has no transaction, and letting ROLLBACK throw would mask the
-  original corruption error in Database.transaction()'s catch path.
-- quick_check failing on the fresh connection means real on-disk corruption:
-  no retry, the original error propagates, and the open-time recovery machinery
-  (Database.recoverIfCorrupt) remains the owner of that case.
-- Reopen attempts are rate-limited (default 30s cooldown) so a persistently bad
-  file cannot cause a tight reopen loop.

-   *
-   * Gated by the `settingsMigrationVersion` `__meta` marker so it runs exactly
-   * once per project DB. The sequence (matching the plan's HTD diagram):
-   *
-   *   1. Read the RAW persisted project + global settings (the typed read can no
-   *      longer see moved keys post-schema-removal, so read the JSON directly);
-   *      snapshot ONLY the moved keys the user actually CUSTOMIZED (present in raw
-   *      storage) — defaults are not snapshotted (they re-derive from declarations).
-   *   2. Compute the write target = distinct `task_workflow_selection.workflowId`
-   *      for this project ∪ the resolved project default, where an unset/empty
-   *      `defaultWorkflowId` normalizes to `builtin:coding` (the id every
-   *      selection-less task resolves to). A default pointing at a deleted/missing
-   *      workflow also degrades to `builtin:coding`.
-   *   3. Validate the snapshot against EACH target workflow's declarations (the
-   *      values came from validated project settings, so this normally passes); a
-   *      value that fails the new validation is DROPPED and logged — never aborts.
-   *   4. In ONE SQLite transaction: upsert the accepted snapshot into each
-   *      `(workflowId, projectId)` value row, null the moved keys out of the raw
-   *      project `config.settings`, and set the marker. (The async validation /
-   *      declaration resolution happens BEFORE the transaction — the transaction
-   *      body is pure synchronous SQLite, so the persisted writes commit atomically.)
-   *   5. Defensively null the moved keys out of the global store (outside the txn;
-   *      all moved keys are project-scoped, so this is belt-and-suspenders).
-   *
-   * Idempotent / crash-safe: value upserts overwrite identically, the raw null-out
-   * is re-runnable, and the marker is set LAST inside the transaction. A crash
-   * between the value-write and the null-out re-runs the whole thing and converges.

+/**
+ * Async Drizzle allocator reconciliation helpers (U12).
+ *
+ * FNXC:TaskStoreAllocator 2026-06-24-14:00:
+ * Async equivalent of the sync `reconcileTaskIdState()` in
+ * distributed-task-id.ts. The allocator reconciliation runs on store open and
+ * bumps each prefix sequence to the high-water mark so new task IDs never
+ * collide with existing, soft-deleted, or archived IDs.
+ *
+ * Behavioral invariants preserved (see docs/storage.md):
+ *   VAL-DATA-007 — On store open, each prefix sequence is bumped to
+ *     max(current, max(task suffix)+1, max(archived suffix)+1, max(reservation)+1).
+ *   VAL-DATA-008 — Soft-deleted/archived IDs stay reserved (never reassigned).
+ *     The reconciliation intentionally scans soft-deleted task rows (no
+ *     deleted_at filter) so a soft-deleted ID continues to hold its sequence
+ *     floor (FN-5105).
+ *
+ * PostgreSQL mapping notes:
+ *   - The `distributed_task_id_state` table uses `prefix` as its primary key
+ *     and `next_sequence` as the per-prefix counter.
+ *   - The reconciliation scans `project.tasks` (including soft-deleted rows)
+ *     and `project.archived_tasks` for the max suffix per prefix.
+ *   - The config-table legacy `nextId` is honored only for the configured
+ *     prefix (deprecated; preserved for one release then dropped).
+ *
+ * Transition context:
+ *   The sync `reconcileTaskIdState(db)` remains the live path until U15 flips
+ *   the connection. This async helper is the PostgreSQL target the integration
+ *   tests exercise; U13/U14 wire it into the store-open sequence.

+ * Async Drizzle archive / lineage helpers (U14).
+ *
+ * FNXC:TaskStoreArchiveLineage 2026-06-24-07:00:
+ * Async equivalents of the sync SQLite archive and lineage call sites in
+ * store.ts and archive-db.ts. These helpers target the PostgreSQL
+ * `project.archived_tasks`, `archive.archived_tasks`, `project.tasks`, and the
+ * document/artifact tables via Drizzle, and preserve the load-bearing archive
+ * and lineage invariants:
+ *
+ *   VAL-CROSS-014 — Soft-deleting a child task allows its parent to be deleted
+ *     (the soft-deleted child no longer blocks). The lineage-integrity gate
+ *     (from async-lifecycle) excludes soft-deleted children, so a parent whose
+ *     only children are soft-deleted can be deleted immediately.
+ *   VAL-CROSS-015 — Archiving a parent task scopes its documents/artifacts out
+ *     of live views but preserves them for restore. When a task is archived,
+ *     its `task_documents` and `artifacts` rows are retained (the FK is
+ *     ON DELETE CASCADE, not ON DELETE SET NULL, so an archive — which is a
+ *     soft column move, not a row delete — keeps them). Live document/artifact
+ *     views filter by the parent task's live state (`deleted_at IS NULL` and
+ *     `column != 'archived'`), so the rows disappear from live views but
+ *     remain for an unarchive restore.
+ *
+ * Transition context (see library/taskstore-persistence-notes.md):
+ *   `getDatabase()` still returns the sync `Database` until U15 flips it. The
+ *   TaskStore facade keeps its sync archive path (the gate depends on it).
+ *   These helpers are the async target the migrating store and the PostgreSQL
+ *   integration tests consume. They program against the stable `AsyncDataLayer`
+ *   interface (U4), not the underlying driver.

+ * FNXC:TaskStoreCommentsAttachments 2026-06-24-09:30:
+ * Async equivalents of the sync SQLite task-document and artifact call sites
+ * in store.ts (`upsertTaskDocument`, `getTaskDocument`, `getTaskDocumentRevisions`,
+ * `registerArtifact`, `getArtifact`, `getArtifacts`). These helpers target the
+ * PostgreSQL `project.task_documents`, `project.task_document_revisions`, and
+ * `project.artifacts` tables via Drizzle.
+ *
+ * Document/artifact parent-task scoping (VAL-CROSS-015):
+ *   Documents and artifacts scoped to a task are read-only when the task is
+ *   archived. The upsert paths reject writes against archived tasks. The list
+ *   paths filter by the parent task's live state (`deleted_at IS NULL` AND
+ *   `column != 'archived'`) so rows scoped to an archived parent disappear
+ *   from live views but are retained for restore.
+ *
+ * JSON columns (VAL-SCHEMA-004):
+ *   The `metadata` columns are jsonb in PostgreSQL. Drizzle returns them
+ *   already-parsed as JS values. On write, pass the JS value directly.
+ *
+ * Transition context (see library/taskstore-persistence-notes.md):
+ *   `getDatabase()` still returns the sync `Database` until U15 flips it. The
+ *   TaskStore facade keeps its sync document/artifact path (the gate depends
+ *   on it). These helpers are the async target the migrating store and the

+ * Plugin activations:

+ *
+ * Transition context (see library/taskstore-persistence-notes.md):
+ *   `getDatabase()` still returns the sync `Database` until U15 flips it. The
+ *   TaskStore facade keeps its sync event path (the gate depends on it).

+ * FNXC:TaskStoreMergeCoordination 2026-06-24-05:15:
+ * Enqueue a task into the merge queue INSIDE a shared transaction handle
+ * (VAL-DATA-013). The handoff-to-review path composes this inside its
+ * `transactionImmediate(async (tx) => ...)` so the column move, this queue
+ * insert, and the audit row all commit or roll back atomically. Observers
+ * never see `column = 'in-review'` without the matching queue row.
+ *
+ * Semantics (mirrors the sync `enqueueMergeQueue` transaction body):
+ *   - Reads the task's `priority` and `column` from `tasks` for the enqueue
+ *     decision. The task MUST already be in `in-review` (the column move in
+ *     the same transaction establishes this); otherwise the enqueue is rejected
+ *     with a column-mismatch error after the caller's transaction.
+ *   - Idempotent on `taskId` (the primary key): a re-enqueue for an already-
+ *     queued task returns the existing row without inserting a duplicate. The
+ *     `ON CONFLICT (task_id) DO NOTHING` makes the insert safe under retry.
+ *   - Records a `mergeQueue:enqueue` audit event using the SAME transaction
+ *     handle so it commits/rolls back with the enqueue.
+ *
+ * @param tx The transaction handle from the caller's `transactionImmediate`.
+ * @param taskId The task to enqueue (must be in `in-review`).
+ * @param opts Enqueue options (explicit priority override, clock injection).
+ * @param audit Optional audit context (agentId/runId) for the enqueue event.
+ * @returns The enqueued (or pre-existing) queue entry.

+ * Async Drizzle monitor-store helpers (U15).
+ *
+ * FNXC:Monitor 2026-06-24-13:00:
+ * Async equivalents of the sync SQLite monitor-store functions in
+ * `packages/dashboard/src/monitor-store.ts`. These helpers target the
+ * PostgreSQL `project.deployments` and `project.incidents` tables via Drizzle,
+ * and program against the stable `AsyncDataLayer` interface (U4) — not the
+ * underlying driver. They preserve the monitor-stage storage and storm-guard
+ * semantics:
+ *
+ *   - Deployments are idempotent upserts keyed by `deploymentId`.
+ *   - Incident ingest absorbs re-firing signals into the open incident for a
+ *     grouping key (occurrence count + updatedAt bumped), otherwise creates a
+ *     fresh `open` incident.
+ *   - The atomic incident-level fix-task claim (`claimIncidentForFixTask`) uses
+ *     a conditional UPDATE (`WHERE fixTaskId IS NULL`) so exactly one concurrent
+ *     caller wins, closing the create-then-link race.
+ *   - The circuit-breaker count excludes stranded sentinel placeholders.
+ *
+ * Transition context (see library/async-data-layer-notes.md):
+ *   `getDatabase()` still returns the sync `Database` until the satellite-store
+ *   sub-features complete and flip the accessor. The dashboard monitor-store
+ *   keeps its sync path (the gate depends on it). These helpers are the async
+ *   target the migrating dashboard store and the PostgreSQL integration tests
+ *   consume.

+ *
+ * FNXC:TaskStorePersistence 2026-06-24-13:00:
+ * Async equivalents of the sync SQLite persistence call sites in store.ts.
+ * These helpers target the PostgreSQL `project.tasks` table via Drizzle and
+ * preserve the three load-bearing persistence invariants the migration must
+ * not regress:
+ *
+ *   VAL-DATA-005 — Soft-delete visibility: every live reader filters
+ *     `deleted_at IS NULL`. Soft-deleted tasks do not appear in active lists,
+ *     kanban, or counts. Forensic reads (includeDeleted) still surface them.
+ *   VAL-DATA-006 — Forensic reads surface soft-deleted rows when explicitly
+ *     requested (includeDeleted: true).
+ *   VAL-DATA-009 — Create-class inserts are non-destructive: create paths use
+ *     a plain INSERT so PostgreSQL raises a primary-key violation on duplicate
+ *     IDs instead of silently rewriting the existing row (the upsert path is
+ *     update-only and must never be used for create).
+ *
+ * SQLite → PostgreSQL JSON note (VAL-SCHEMA-004):
+ *   In SQLite the JSON columns were TEXT with `toJson()`/`fromJson()`. In
+ *   PostgreSQL they are `jsonb`, so Drizzle returns them already-parsed as JS
+ *   values. On write, pass the JS value directly (Drizzle serializes it).
+ *
+ * Transition context (see library/satellite-store-migration-pattern.md):
+ *   `getDatabase()` still returns the sync `Database` until U15 flips it. The
+ *   TaskStore facade keeps its sync persistence path (the gate depends on it).
+ *   These helpers are the async target the migrating stores (U13/U14) and the
+ *   PostgreSQL integration tests consume. They program against the stable
+ *   `AsyncDataLayer` interface (U4), not the underlying driver.

+ * Async Drizzle task-search query-structure helpers (U14).
+ *
+ * FNXC:TaskStoreSearch 2026-06-24-10:30:
+ * Async query-structure helpers for task full-text search. This module captures
+ * the query predicates and token-sanitization logic that the FTS5 path in
+ * store.ts used, expressed against the PostgreSQL `project.tasks` table via
+ * Drizzle. The actual tsvector/GIN full-text search implementation is delivered
+ * by the `fts-replacement` feature (separate milestone); this module provides
+ * the LIKE-based fallback query structure and the shared predicate builders
+ * (soft-delete filtering, archived filtering, token sanitization) that
+ * fts-replacement builds on top of.
+ *
+ * The search query structure preserves these invariants:
+ *   - Soft-delete visibility: live search filters `deleted_at IS NULL`
+ *     (VAL-DATA-005). Soft-deleted tasks never appear in search results.
+ *   - Archived filtering: when `includeArchived` is false, archived tasks
+ *     (`column = 'archived'`) are excluded.
+ *   - Token sanitization: FTS5 operators are stripped so both code paths see
+ *     the same token set. Empty/whitespace queries fall back to listTasks.
+ *
+ * Transition context (see library/taskstore-persistence-notes.md):
+ *   `getDatabase()` still returns the sync `Database` until U15 flips it. The
+ *   TaskStore facade keeps its sync search path (the gate depends on it).
+ *   These helpers are the async target the fts-replacement feature and the
+ *   PostgreSQL integration tests consume.

+Ported from upstream's sqlite-backed version: the sqlite ChatStore path is removed on this

+an in-memory FakeChatStore implementing the async ChatStore surface ChatManager touches
+(getSession/getMessage/deleteMessagesFrom/updateMessageMetadata/setCliSessionFile). The store
+truncation semantics themselves are covered against real PostgreSQL in
+packages/core/src/__tests__/postgres/chat-store-content-search-edit.pg.test.ts; the seam under
+test here is the pi session branch/repoint behavior, which is store-agnostic.

-
-FNXC:DashboardTests 2026-06-25-10:30 (FN-5048 — slowest dashboard file):
-This suite previously paid a full TaskStore.init()/migrate + createServer() (the entire
-2.4k-line Express app wiring) on EVERY test via beforeEach, and recreated a temp dir per
-test with retry-prone cleanup — ~26.5s under full-suite pressure. The HTTP layer here is
-synthetic (test-request.js calls app(req,res) directly; no real port), so the per-test
-server boot bought nothing but cost.
-
-FNXC:DashboardTests 2026-06-27-06:50 (FN-7114 — import-cost trim):
-Measurement showed the remaining cost was module transform/import, not test execution: importing server.ts forced broad dashboard chat/runtime wiring and the @fusion/engine importActual graph. Keep coverage at the route boundary by booting storeA once and mounting createInsightsRouter in a tiny Express app with the same JSON/error payload shape these assertions exercise. Mock only the engine exports this router consumes (createFnAgent, promptWithFallback, resolveMcpServersForStore) so the suite no longer transforms the full engine graph.
-Isolation is preserved by truncating the three insight tables between tests (resetInsightTables) instead of rebuilding the store — assertions are untouched, order-independence is real, not papered over.
-Timer seam: any interval/sweep-driven path is driven with FAKE timers + advanceTimersByTimeAsync
-(see "runs periodic sweep" below) so we never wait the real 5-minute DEFAULT_SWEEP_INTERVAL_MS;
-afterEach restores real timers so non-timer tests are unaffected.

FN-7444 added planning-summary deepening constants (PLANNING_DEEPEN_PROCEED_OPTION_ID etc.) that src/planning.ts imports from core; a fully hand-written mock omitted them and made createServer fail to load with "No export is defined on the @fusion/core mock". Spreading importOriginal keeps every real export (including future additions) resolvable while the explicit keys below retain the focused mock behavior. This also removes the prior duplicate CLI_AGENT_ADAPTER_IDS / sanitizeCliAgentSettings keys (a merge artifact whose second copy silently won).

-/**
- * Scoped Scheduling Resolver Regression Tests
- * ===========================================
- *
- * These tests verify the scoped scheduling resolver invariants across automation and routine routes.
- *
- * Scope Resolution Precedence:
- * 1. scope=global → Uses the default AutomationStore/RoutineStore from options (process-level)
- * 2. scope=project → Uses the same store with scope filtering at query time
- * 3. Omitted scope (legacy) → Defaults to project for POST, returns all for GET
- *
- * Error Contracts:
- * - 400: Invalid scope value ("invalid" is not "global" or "project")
- * - 503: Store unavailable when scope is specified
- * - 200: Empty array when store is unavailable (legacy fallback for backward compatibility)
- *
- * Cross-Project Isolation:
- * - scope=project requests never leak global-scoped items into results
- * - scope=global requests never include project-scoped items
- * - No opportunistic lane hopping: when scope=project has no results, it returns empty,
- *   NOT the global lane results
- *
- * Fallback Behavior:
- * - When no AutomationStore/RoutineStore is configured, GET endpoints return []
- *   (This is a legacy backward-compatible behavior)
- * - POST endpoints requiring a store will throw if no store is configured

-// HOLD/RELEASE SWEEP SUITE (U6).
-//
-// Exercises the generalized scheduler sweep (`hold-release.ts`) against a REAL
-// TaskStore so the in-txn capacity check (KTD-10) actually arbitrates races:
-//   - two holds, one slot → exactly one releases; other retries next sweep
-//   - timer release fires at its deadline under fake timers (no real sleeps)
-//   - manual release only on the explicit promote call
-//   - capacity release respects mid-transitionPending cards (in-txn authority)
-//   - cross-workflow dependency complete-flag unblocks + dual-accept diff logged
-//   - sweep release into a full column rejected by the in-txn check despite
-//     moveSource:"scheduler" bypassing trait guards (capacity is not a guard)
-//   - reservation-first: semaphore exhausted → no commit, card stays held
-//   - paused / recovery-backoff tasks skipped exactly as the legacy scheduler

-/**
- * U7 — Merge trait behavior (R10).
- *
- * Covers every U7 plan scenario:
- *   - each `strategy` value routes to the merger behavior it names, incl.
- *     `pr-only` (enqueue-with-prState marker, documented below);
- *   - `fileScope` off / warn / strict / custom behaviors incl. audit payloads;
- *   - lost-work guard trio regression: config CANNOT reach the three guards;
- *   - merge completion drives the next column via the queue callback, not
- *     inline;
- *   - a queued merge surviving restart resumes from SQLite state (fixture).
- *
- * Fast: mock stores + a single in-memory `TaskStore` (no real git, no real
- * merges). No process spawns; no fake-timer-dependent waits.
- *
- * PR-ONLY DESIGN DECISION: there is no PR-creation path inside the merge queue
- * in this codebase — the merge-queue worker loop runs `aiMergeTask` (a direct
- * merge). So `pr-only` is implemented as a *routing flag* on the resolved
- * policy (`pullRequestOnly: true`), consistent with the existing
- * `settings.mergeStrategy === "pull-request"` posture: `merger.ts` skips
- * direct-merge commit routing exactly as it does for the pull-request setting.
- * The card still enqueues onto the same persisted merge-request queue; the
- * pr-state marker is the existing pr-monitor machinery's concern. This is the
- * narrowest change that makes `pr-only` behave like the pull-request route
- * without reimplementing merge mechanics.

-/**
- * U5 — PR review-response run (the fix-or-disagree agent loop).
- *
- * Covers every U5 hard requirement against a real in-memory TaskStore + fakes
- * for the injected GitHub ops, agent runner, and git ops:
- *   - AE1: actionable comment → fix committed, pushed, thread replied (marker+SHA),
- *          resolved, outcome persisted, emits "fixed".
- *   - AE2: disagreement → reasoned reply, no push for that thread, thread left
- *          unresolved, marker-tagged.
- *   - Prompt-injection defense (delimited untrusted body + system declaration).
- *   - Marker spoofing (third-party valid marker does NOT suppress).
- *   - Bot denylist (`*[bot]` never dispatches).
- *   - Pre-push secret scan (credential blocks the push).
- *   - Non-ff abort + NO force-push.
- *   - Restart recovery: persisted row → skip; pushed-marker → skip (no dup fix).
- *   - Iteration cap → run suppressed.
- *   - Detached-turn: never throws; abort honored.

-/**
- * U9 — built-in PR workflow end-to-end (FAST, faked GitHub + faked agent).
- *
- * Proves the headline "wire it end to end" deliverable: a task routed through the
- * built-in PR workflow graph (`BUILTIN_PR_WORKFLOW_IR`) flows through the full
- * node lifecycle — create → await-review → (changes-requested) respond →
- * (approved) auto-merge gate → merge → end — with the U4 reconcile firing the
- * external-event releases that advance the await holds.
- *
- * The executor cannot itself park at a hold (holds are dwell columns the runtime
- * parks/resumes the card at; the executor has no hold handler). So this drives the
- * lifecycle in the same SEGMENTS the runtime does, resuming the graph at each next
- * node, and uses the real {@link PrReconciler} to prove a GitHub state change fires
- * the matching `github:pr-<event>` release between segments. The PR node handlers
- * (pr-create / pr-respond / pr-merge / auto-merge gate) run with injected fakes —
- * the engine never touches a real GitHub client.
- *
- * It also pins that the built-in IR parses/validates and round-trips.

-/**
- * U7 — Recovery / reaper safety falsification audit (R15) + reaper→slice
- * deadlock regression (the P0).
- *
- * The verification run (U3) is the first side-effecting path in a subsystem
- * whose recovery/reaper logic historically assumed validation was
- * side-effect-free. This suite *falsifies* (does not merely confirm) that every
- * site that re-drives validation stays correct now that verification can have
- * effects. For each re-drive entry point enumerated in
- * `docs/missions.md` → "## Surface Enumeration", we assert the post-conditions:
- *
- *   1. The source tree feeding diff/merge is git-clean after a run (no FS
- *      residue) — enforced here via a verification capability that records every
- *      invocation and asserts its disposable-surface contract, plus the absence
- *      of any board task created by validation.
- *   2. Zero duplicate Fix Features on re-drive (idempotent on
- *      (sourceFeatureId, runId)).
- *   3. A terminal verdict (passed / failed / blocked) is reached — never an
- *      indefinitely re-driven `error`.
- *   4. No `error`-state slice deadlock: a reaped-near-the-bound run does not
- *      strand the slice across a subsequent recovery sweep.
- *
- * Re-drive entry points covered (see Surface Enumeration):
- *   - `processTaskOutcome` (normal, task-triggered)
- *   - `recoverActiveMissionValidations` branches:
- *       · validating
- *       · needs_fix + taskId
- *       · implementing + taskId
- *       · stranded done (implementing, no task) — original orphan
- *       · reaped done (needs_fix + error, no task) — the P0 deadlock
- *   - `reapStaleMissionValidatorRuns`
- *
- * These tests gate release.

+ * expose the same store method names/shapes, so the orchestrator types `store` as
+ * the union and `await`s every store call — a sync method's awaited return is
+ * identical to its direct return, so lifecycle semantics are preserved across both
+ * backends. Mirrors the InsightRunExecutor union+await port. Note: the async store
+ * exposes `appendEvent` (not the sync-only `addEvent`), so all event writes here go
+ * through `appendEvent`, which the sync store also implements as an alias.

+/**
+ * FNXC:PostgresCutover 2026-07-04-00:00:
+ * PG integration test for CePipelineStore's async path (item 10).
+ *
+ * Exercises every *Async() sibling against a real backend-mode AsyncDataLayer.
+ * The CE plugin tables (ce_pipeline_links, ce_pipeline_state, ce_pipeline_sync_queue)
+ * must materialize via the cePluginSchemaInit hook registered in
+ * DEFAULT_PLUGIN_SCHEMA_INIT_HOOKS — the schema applier runs it when
+ * applySchemaBaseline() is called below. If the hook is unwired, the first
+ * insert throws 'relation "project.ce_pipeline_links" does not exist'.
+ *
+ * Self-contained: uses only the @fusion/core public surface plus a single psql
+ * call for test-DB lifecycle (same pattern as core's data-layer.test.ts).
+ * Auto-skipped when FUSION_PG_TEST_SKIP=1 or no PG at localhost:5432.
