+# Tasks — `@suaveplan/api-db-adapter`
+
+> Every checkbox MUST reflect work actually done in this change.
+
+## 0. Pre-flight (non-negotiable)
+
+- [ ] 0.1 Confirm clean working tree (`git status` reports nothing) and no in-flight worktrees with uncommitted work (`git worktree list` then `git status` in each)
+- [ ] 0.2 If any worktrees exist under `.claude/worktrees/`, account for each one: still-active agent, work-pending-merge, or stale-and-prune. Stale worktrees MUST be removed (`git worktree remove`) before opening a new one — code that has been lost twice on main is the failure mode this guards against.
+- [ ] 0.3 Confirm the package set in `MANIFEST.md` matches `find packages -maxdepth 3 -name package.json` count. Drift here means a prior change archived without regenerating the manifest.
+
+## 1. Spec authoring
+
+- [x] 1.1 Read design doc (§3, §5.1, §5.2a, §13.4)
+- [x] 1.2 Read `openspec/changes/api-db-worker-proxy/`, `@suaveplan/db` README for downstream contract
+- [x] 1.3 Read `openspec/AGENTS.md` Sections 13 and 14
+- [x] 1.4 Draft `proposal.md`
+- [x] 1.5 Draft `specs/api-db-adapter/spec.md`
+- [x] 1.6 Every requirement carries `**Verified by:**`
+
+## 2. Implementation
+
+- [ ] 2.1 Scaffold `packages/api/api-db-adapter/` (deps: api-db, api-types, api-worker-rpc, db, error, zod)
+- [ ] 2.2 `src/options/db-adapter-options.ts` — Zod schema
+- [ ] 2.3 `src/factory/create-db-adapter.ts` — direct surface (admin + scoped)
+- [ ] 2.4 `src/proxy/create-db-adapter-worker-proxy.ts` — proxy with transferable `ReadableStream` cursors
+- [ ] 2.5 `src/tenant-scoping/create-tenant-scoped-wrapper.ts` — `WHERE`/`INSERT` injection + read rejection
+- [ ] 2.6 `src/migrations/run-migrations.ts` — per-engine migration runner with `__plugin_migrations` table
+- [ ] 2.7 `src/engines/postgres-engine.ts`, `src/engines/sqlite-engine.ts`, `src/engines/surrealdb-engine.ts` — per-engine adapters
+- [ ] 2.8 `src/unsafe/unsafe-query-gate.ts` — capability check + `plugin.unsafe_query_total` counter
+- [ ] 2.9 `src/error-codes.ts` — `DB_ADAPTER_*` codes via `defineCodes`
+- [ ] 2.10 `src/index.ts` — explicit named re-exports
+
+## 3. Tests
+
+- [ ] 3.1 `src/factory/create-db-adapter.test.ts` — against in-memory SQLite
+- [ ] 3.2 `src/factory/create-db-adapter.spec-conformance.test.ts` — direct conformance
+- [ ] 3.3 `src/proxy/create-db-adapter-worker-proxy.test.ts` — proxy + ReadableStream cursor
+- [ ] 3.4 `src/proxy/create-db-adapter-worker-proxy.spec-conformance.test.ts` — proxy conformance
+- [ ] 3.5 `src/tenant-scoping/create-tenant-scoped-wrapper.test.ts`
+- [ ] 3.6 `src/migrations/run-migrations.test.ts` — per-engine forward + idempotency
+- [ ] 3.7 `src/unsafe/unsafe-query-gate.test.ts`
+- [ ] 3.8 `tests/integration/postgres.test.ts` — real Postgres
+- [ ] 3.9 `tests/integration/surrealdb.test.ts` — real Surreal
+- [ ] 3.10 Every `it(...)` carries `{ timeout: 5000 }` (30000 for integration)
+
+## 4. Documentation
+
+- [ ] 4.1 Sibling `.md` per implementation `.ts`
+- [ ] 4.2 README documents tenant-scoped wrapper semantics, the unsafe escape hatch, and the per-engine migration directory layout
+
+## 5. Pre-archive verification (5-gate triple)
+
+- [ ] 5.1 `bun run check` — clean
+- [ ] 5.2 `bunx turbo lint typecheck test --filter=@suaveplan/api-db-adapter` — green
+- [ ] 5.3 `bunx turbo test:coverage --filter=@suaveplan/api-db-adapter` — 100/100/100/100
+- [ ] 5.4 `bun scripts/openspec-conformance.ts @suaveplan/api-db-adapter` — exit 0
+- [ ] 5.5 `bunx turbo build --filter=@suaveplan/api-db-adapter` — green
+
+## 6. Pre-archive 7-row checklist
+
+- [ ] 6.1 Generics threaded through `AdminDatabaseLike` / `TenantScopedDatabaseLike`; `expectTypeOf` asserts the two surfaces are not interchangeable
+- [ ] 6.2 Zod schemas at options + manifest boundaries
+- [ ] 6.3 Every `DB_ADAPTER_*` code thrown by at least one production path
+- [ ] 6.4 Strict-mode (auto-inject vs reject on missing tenant column) tested both ways
+- [ ] 6.5 OTel instruments (`api.db.query_duration_ms`, `api.db.migrations_applied_total`, `plugin.unsafe_query_total`) asserted with in-memory `MeterProvider`
+- [ ] 6.6 Migration idempotency tested (running twice = same version state)
+- [ ] 6.7 No retroactive tick
+
+## 7. Archive
+
+- [ ] 7.1 Fold into `openspec/specs/api-db-adapter/spec.md`
+- [ ] 7.2 Move to `openspec/archive/<yyyy-mm-dd>-api-db-adapter/`
+- [ ] 7.3 Tick Stage 4 box in umbrella tasks
+- [ ] 7.4 Refresh `MANIFEST.md`
