GPT Review — P9 Tier 3 Readiness Package

Date: 2026-04-27
Scope: Review knowledge/dev/laws/dieu38-trien-khai/P9-tier3-readiness-package.md rev 1 and index.md rev 39.

Verdict

PASS. Tier 3 readiness package is accepted. Proceed to G6 migration dry-run as the next bundled execution block.

Evidence checked

• knowledge/dev/laws/dieu38-trien-khai/P9-tier3-readiness-package.md rev 1 — G6/G8/G11 readiness package.
• knowledge/dev/laws/dieu38-trien-khai/index.md rev 39 — E6 PASS, P9 Gate 9/12 PASS, remaining G6/G8/G11.
• knowledge/dev/reports/gpt-review-e6-post-remediation-pass-2026-04-27.md — GPT PASS for E6 and direction to Tier 3.

Review findings

1. Ledger update PASS. Index now records E6 PASS and P9 Gate progress 9/12.
2. G6 readiness PASS. The package correctly identifies the migration dry-run surface: DDL compile, 14 tables, FK/constraints/indexes, seed authority/SHA-256, verification, rollback.
3. G8 readiness PASS with dependency. The package correctly states G8 depends on G6 because Directus role permissions require collections to exist.
4. G11 readiness PASS. User approval is correctly kept inactive until G6 and G8 are PASS.
5. No mutation performed. The readiness package is doc-only and respects current gates.

Law / constitutional check

Rule	Result	Finding
Hiến pháp / 100% DOT	PASS	Readiness only; execution remains agent/DOT-governed.
Đ33 API/DB governance	PASS	Future dry-run must be isolated/non-production; production DDL/DML remains forbidden.
Đ35 DOT governance	PASS	G8 must use DOT/Directus-governed path after G6.
Đ32 approval discipline	PASS	G11 approval remains final gate, not active now.
Đ24	PASS	No label/entity_label mutation.
Zero Trust	PASS	Remaining gates and dependencies are explicit.

Guardrails for next block

G6 dry-run may use VPS/DB through Opus/agent, but must be isolated from production:

• Use a disposable test schema, e.g. p9_g6_dryrun_*, or a clearly non-production sandbox schema.
• Do not write to production public.tac_*, Directus production collections, roles, permissions, taxonomy, entity_labels, or system_issues.
• No P9 migration execution.
• Any production mutation discovered as necessary must stop and become a separate gate.

Direction

Proceed to G6 Migration Dry-run block. Opus should run it as a substantial single milestone, not micro-patches:

1. Generate the migration DDL/API plan from P8/P5 design.
2. Run the dry-run in isolated non-production schema only.
3. Verify table count, constraints, FK, indexes, functions/triggers, seed SHA plan, and rollback cleanly removes the test objects.
4. Produce a single G6 dry-run report with PASS/FAIL, blockers, exact artifacts, and rollback evidence.
5. In parallel, keep G8/G11 as doc-only readiness notes only; do not create roles/permissions or request G11 approval yet.

If G6 PASS, next block should be G8 Directus collections/roles execution design + gate. If G6 FAIL, report the blocker and proposed fix without mutating production.
