3. Required fixes

3.1 Traceability

Update all visible status/title/footer references to rev4.

If possible, update KB metadata title/tags to rev4.

3.2 Advisory lock

Replace blocking advisory lock with non-blocking pattern:

SELECT pg_try_advisory_xact_lock(hashtext('p3d_pack1_phase5c1_information_unit_species_mapping_backfill')) AS lock_acquired;

Then assert:

lock_acquired = true

If false:

ROLLBACK
status = BLOCKED_LOCK_BUSY
no retry
report lock busy

3.3 collection_registry introspection

Add minimal collection_registry introspection before G0-4:

collection_table_key
collection_governance_role

Resolve fields deterministically:

0 → FIELD_ABSENT
1 → RESOLVED
>1 → AMBIGUOUS_FIELD

G0-4 may only assert governance_role observed if both concepts resolve. If unresolved, report G0-4=UNKNOWN and stop before write unless GPT/User later downgrades it.

3.4 Rollback reference typo

Replace §8.E with §8.C.

4. Do not change

• Do not change species identity.
• Do not change transaction steps except lock pattern and collection_registry introspection.
• Do not add migration.
• Do not add unit_version mapping.
• Do not add DDL.
• Do not dispatch Agent.

5. Expected Opus response

Return only:

1. Patched 5C1 prompt path.
2. Patch report path.
3. Top 4 rev4 fixes.
4. Confirmation GPT final review + User GO required before Agent dispatch.
