dot-iu-cutter v0.2 — Phase α Production Handoff / Status

Path: knowledge/dev/laws/dieu44-trien-khai/v0.2-execution/dot-iu-cutter-v0.2-phase-alpha-production-handoff-status-2026-05-16.md Date: 2026-05-16 Author: dot-iu-cutter operator (closeout session) Builds on: Phase α production execution report (2026-05-16) + GPT review verdict Scope of this document: CLOSEOUT / HANDOFF ONLY — no migration, no DDL, no manifest design.

---

1. Phase α Final Status

Field	Value
phase_alpha_production_execution_status	PASS (GPT-ratified)
execution_status	success
rollback_executed	false
scope_expansion	false
non_scope_performed	false
State	v0.2 Phase α is LIVE in production

GPT reviewed the Phase α Production Execution Report and returned PASS. The migration applied the frozen revision-2 (r2) DDL verbatim (dot-iu-cutter-v0.2-phase-alpha-r2.sql, sha256 65533e05…893fe3) in a single committed transaction (C-07 psql exit 0, status COMMITTED). No rollback was triggered (C-09 NOT triggered). Scope was exactly the authorized Phase α subset.

2. Production Objects Added

Target DB: directus on container postgres (PostgreSQL 16.13), VPS 38.242.240.89.

2.1 public.tac_logical_unit — new columns

• authority — distribution: draft = 86, enacted = 0, runtime = 0, null = 0
• canonical_address_format_version — distribution: canonical-address-v1 = 86

2.2 sandbox_tac.logical_unit — new columns

• authority — distribution: null = 76
• canonical_address_format_version — distribution: canonical-address-v1 = 76

2.3 cutter_governance.canonical_address_alias — new table

• Rows = 0 (empty, as authorized — no alias writes performed)
• 4 indexes created
• cutter_governance schema now holds 6 tables = 5 v0.1 tables (decision_backlog_entry, dot_pair_signature, cut_change_set, cut_change_set_affected_row, verify_result) + canonical_address_alias

3. Verification Summary (from production execution)

Gate	Result
C-06 preflight	10/10 PASS
C-07 migration	psql exit 0, UPDATE 86, status COMMITTED
C-08 verify (verify_alpha.sql)	PASS — 17 verify-pass lines
Schema DDL diff	added = 6, removed = 0
updated_at rows changed	86 / 86 (BR-4 backfill)
C-09 rollback	NOT triggered

All results match the dry-run (pg-dry-run-v0.2-phase-alpha-2026-05-16) exactly.

4. Accepted updated_at Side Effect

The migration bumped updated_at on all 86 public.tac_logical_unit rows (pre distinct = 3, range 2026-04-29…2026-04-30 → post distinct = 1, 2026-05-16 02:27:27.789235+00). This is accepted as the expected BR-4 backfill side effect: the r2 DDL backfills authority/canonical_address_format_version on existing rows, which touches updated_at. This pattern is the proof that r2 DDL executed, not the rejected r1 pattern. No business data values were altered — only the two new columns were populated and the audit updated_at was bumped.

5. Rollback Status

• rollback_executed = false
• C-09 rollback path NOT triggered — no rollback was needed.
• The pre-migration safety backup (phase_alpha_prod_20260516T022657Z.dump, sha256 e0b178a9…) remains retained for defence-in-depth, but is not a Phase-α-state backup (taken 2 s before C-07). The Phase-α-state backup is documented in the companion post-execution backup verification report.

6. What Remains UNAUTHORIZED

The following are explicitly out of scope and not authorized:

• Production CUT operations (no INSERT into cut_change_set)
• Production VERIFY operations (no INSERT into verify_result)
• Alias writes (no INSERT into cutter_governance.canonical_address_alias)
• P0-2 manifest design — manifest_envelope, manifest_unit_block
• P0-6 review_decision
• Any further migration / DDL
• App / tooling integration (no connector or application wiring against the new columns)

Each requires its own design → dry-run → command-review → GPT ratify → explicit User execution prompt in a separate session. Operator self-advance is PROHIBITED.

7. Dry-Run Environment Status

Both isolated dry-run environments remain UP and are protected (must not be torn down without explicit authorization):

Container	Image	Status	Volume
pg-dry-run-hb05-2026-05-15	postgres:16	UP	pg-dry-run-hb05-2026-05-15-data
pg-dry-run-v0.2-phase-alpha-2026-05-16	postgres:16	UP	pg-dry-run-v0.2-phase-alpha-2026-05-16-data

Confirmed still UP after the post-execution backup/restore verification (the restore test used a separate ephemeral container that was created and destroyed by the verification script — neither protected env was touched).

8. Next Recommended Steps

1. Backup closeout — see companion document dot-iu-cutter-v0.2-phase-alpha-post-execution-backup-verification-2026-05-16.md (status: PASS, restore-tested).
2. Route decision — see knowledge/dev/laws/dieu44-trien-khai/v0.2-planning/dot-iu-cutter-v0.2-next-phase-routing-note-2026-05-16.md. Recommended route: absorb BR-6 (split/merge TD) before starting P0-2 manifest design.
3. Do not self-advance into P0-2 / manifest / further migration. Await GPT + explicit User prompt for the next gated step.
