Current state confirmed

Pack 1 is CLOSED — PASS. Production PG has:

• dot_config vocab seeds: 3 keys live.
• information_unit: live, 0 rows.
• unit_version: live, 0 rows.
• fk_iu_version_anchor: deferrable and initially deferred.
• IU triggers active: trg_iu_updated_at, trg_iu_birth_gate_layer1, trg_iu_birth_gate_layer2.
• Smoke tests T1–T14 PASS.
• Test data cleanup complete: both IU tables 0 rows.
• Hard stop remains active: no Pack 2 execution, no outbox, no Qdrant, no Directus integration, no production units.

Review of file 10

Verdict: PASS as Pack 2 readiness / scope decision document.

Criteria:

1. Uses Pack 1 evidence correctly: PASS.
2. Covers F1–F3 clearly: PASS.
3. Keeps hard stop and does not execute Pack 2: PASS.
4. Separates Option A/B/C clearly: PASS.
5. Recommendation is strategically sound: PASS — do Option A first, then decide Option B. Do not jump to vector/outbox.

Important nuance

File 10 says F1 registration may be only metadata INSERT and “not DDL”. This should be treated as a hypothesis until Claude Code inspects the actual TRIGGER-GUARD implementation. The execution prompt for Option A must require a read-only discovery checkpoint before any write.

File 10 says F3 collection_registry registration is tied to Đ13 Live Catalog. It should be done as readiness metadata only, not Directus managed collection exposure, unless explicitly approved.

Recommended next action

Approve Option A only:

• A1: Inspect TRIGGER-GUARD implementation and identify the legitimate registration mechanism.
• A2: Register the 3 IU triggers if and only if a safe registry/whitelist mechanism exists.
• A3: Inspect collection_registry schema and current conventions.
• A4: Register information_unit and unit_version as catalog/readiness entries if schema and conventions are clear.
• A5: Verify no data rows were added to IU tables, no DDL was run, no Directus exposure occurred, no outbox/Qdrant objects were created.

Execution should be via Opus preparing one larger Option A execution pack/prompt for Claude Code, with checkpoints and rollback. User approval required before runtime writes.

Roadmap position

Track 0 DONE. Track A DONE. IU-0 baseline DONE. Pilot Round 1 DONE. Pack 1 DONE. Pack 2 Readiness Pack DONE/PASS. Next: Option A governance cleanup execution pack, then decide Option B Minimal CRUD/API pilot. Pack 3 outbox/vector remains deferred.
