+# RMGR-WP-0005 batch 0003 Markitect cutover
+
+**Completed at:** `2026-08-22T14:47:56Z`
+
+**Scope:** `markitect-main` only
+
+**Decision:** `RMGR-DEC-2026-002` (`approved`)
+
+## Outcome
+
+The approved repository-atomic batch completed in both current State Hub
+projections and the authoritative repository. No other identifier mapping was
+applied.
+
+| Kind | Record | Previous UUID | Derived UUID |
+| --- | --- | --- | --- |
+| Workplan | `MARKITECT-WP-0002` | `e203d487-01f1-494a-b14d-a436241a4c01` | `e03ef262-5284-5dd3-92d2-dbd85c6b6159` |
+| Task | `MARKITECT-WP-0002-T01` | `88b3c206-4d45-4bb3-bbb3-47443cdf2123` | `1852eca1-92e2-518e-bb21-9dffbeb32a4f` |
+
+The source plan seal was
+`ac97f6e4f0b35db63a0dc1b4a439f0a39738d13c1407f18419f706d780d4eea0`.
+The approved batch seal was
+`494db8e101aeae7f8488082565dec3b4dd5c9c6ccb5f8812aaf233f813768f67`.
+The no-drift gate was repeated after approval and passed against pinned source
+HEAD `3a45d51bbad49512d2610950eccaa3c2782a8523`.
+
+## Restore points
+
+Fresh PostgreSQL custom-format archives were retained before mutation and
+successfully enumerated by `pg_restore --list`.
+
+| Projection | Archive | Bytes | SHA-256 | Archive entries |
+| --- | --- | ---: | --- | ---: |
+| Workstation | `/tmp/state-hub-markitect-batch-0003-workstation-preapply.dump` | 4,644,612 | `4c18f737c0d2711f0c08fb9d33eaba1b02ccbd4609e51d915ee91fc22a7a2032` | 423 |
+| Production | `/tmp/state-hub-markitect-batch-0003-production-preapply.dump` | 4,801,559 | `7333bd89ac8f3dc75ae9228918da85a4472ca29e7013973d18c0a8efa02c9ae6` | 425 |
+
+The durable alias reverse executor remains available in each projection; the
+restore archives are the database-level fallback.
+
+## Projection transaction
+
+The State Hub repository transaction ran first on the workstation projection
+and then inside the production State Hub runtime. Both executions reported two
+replacements, zero deferred assignments, direction `forward`, and the exact
+source-plan seal above.
+
+Final direct database and API checks agree:
+
+| Check | Workstation | Production |
+| --- | ---: | ---: |
+| Previous workplan UUID rows | 0 | 0 |
+| Derived workplan UUID rows | 1 | 1 |
+| Previous task UUID rows | 0 | 0 |
+| Derived task UUID rows | 1 | 1 |
+| Tasks linked to derived workplan | 10 | 10 |
+| Progress events linked to derived workplan | 9 | 9 |
+| Progress events linked to derived task | 0 | 0 |
+| Applied aliases for the batch mappings | 2 | 2 |
+| Previous UUID API lookups | 404/404 | 404/404 |
+| Derived UUID API lookups | 200/200 | 200/200 |
+
+## Authoritative file transaction
+
+`rmgr identifier migration-files` changed only
+`workplans/MARKITECT-WP-0002-testdrive-jsui-publication.md`, replacing the two
+mapped frontmatter values. The reviewed diff passed `git diff --check` and was
+pushed as `markitect-main` commit
+`e26bd8b7eb8531be222edf42ba0604b1b05250e3`.
+
+Two consistency passes ran against each projection. They were identifier- and
+status-idempotent and produced no source change. The checkout remains clean and
+synchronized at the migration commit.
+
+## Existing conformance warnings
+
+The consistency passes retained pre-existing, non-identifier warnings:
+`markitect-main` lacks the product-flavor `INTENT.md` and `README.md`; nine
+database tasks have no file backing; and `MARKITECT-WP-0001`/`0002` logical ids
+also occur in `markitect-project`. These findings did not change during the
+cutover and were outside the UUID-only approval.
+
+## Rollback posture
+
+Rollback was not invoked. If later required, reverse the authoritative file
+transaction first, then reverse production and workstation projection
+transactions through the durable aliases. Restore from the archives only after
+an isolated restore rehearsal.

+**Batch 0003 completed (2026-08-22):** `RMGR-DEC-2026-002` approved the exact
+sealed `markitect-main` package. Fresh workstation and production restore
+points were created and verified before both projection transactions replaced
+the workplan and task UUIDs. The authoritative two-line file transaction was
+pushed in `markitect-main` commit `e26bd8b7`. Both projections now return
+old/new API lookups 404/200 for both records, retain 10 tasks and 9 progress
+events under the derived workplan, retain zero references to the mapped task,
+and carry two applied aliases. Two consistency passes against each projection
+were identifier- and status-idempotent. Full restore hashes, commits, checks,
+and pre-existing conformance warnings are in
+`docs/evidence/RMGR-WP-0005-batch-0003-markitect-cutover-2026-08-22.md`. T04
+remains in progress for separately sealed and approved fleet batches.
