+# Task: Finalize RDS PostgreSQL integration into main
+
+## Identity
+
+- Task ID: 20260812-integrate-rds-postgres-a91f4d
+- Mode: Integration
+- Branch: codex/20260812-integrate-rds-postgres-4e61c2-integrate-rds-postgres-4e61c2
+- Worktree: D:\Datas\OthersProjects\NianAIGC-integration-rds-4e61c2
+- Base commit: 79d29bbf31f04f3fba1ba57d5df29a3d169e7163
+- Owner: codex
+- Status: Ready for Integration
+
+## Scope
+
+- Finalize the already-reviewed RDS/ACK implementation and canonical project-memory integration on top of `main`.
+- Correct canonical commit references after the feature patch was rebased onto the document-initialized main history.
+- Verify the clean integration head and fast-forward `main` without rewriting history.
+
+## Intent And Constraints
+
+- Treat the completed Docker and RDS task records as read-only source records.
+- Preserve the exact reviewed RDS/ACK patch; use `git range-diff` to verify equivalence after rebase.
+- Do not claim live RDS, Docker daemon, or ACK rollout validation.
+
+## Outcome
+
+- Source feature patch `84d84ba` was rebased without semantic changes as `c44274f` on top of main commits `4177570` and `d019208`.
+- Canonical backend, migration, workload, and deployment boundaries are integrated in project memory.
+- ACK manifest validation now normalizes CRLF and passes on Windows.
+- Integration is ready for a fast-forward update of `main` to the final integration head.
+
+## Verification
+
+- `git range-diff 0bcb149..84d84ba d019208..c44274f` reported the feature patch as equivalent.
+- `npm ci --ignore-scripts` passed.
+- `npm test -- --run` passed: 31 files / 119 tests.
+- `npx tsc --noEmit --pretty false --incremental false` passed.
+- `npm run deploy:check` passed: 8 ACK manifests.
+- `pnpm install --lockfile-only --frozen-lockfile` passed.
+- `npm run build` passed and includes `/api/ready`.
+- Source task final and incremental Sol reviews returned `PASS`.
+
+## Follow-ups
+
+- Validate migrations, TLS, permissions, image runtime, and rollout against the real RDS/ACK environment before production cutover.
+
+## Promotion Candidates
+
+- None recorded.
