Verdict

Status: PASS_ACCEPTED

B3-F1b soft gate execution is accepted. The collection_registry soft gate is now LIVE in PG.

Boundary confirmation

• Only the reviewed rev3 CREATE statements were executed.
• No CREATE OR REPLACE was used.
• No COMMENT ON was executed.
• No ALTER was executed.
• No DML was performed by the prompt.
• No DML smoke test was performed.
• No system_issues or system_health_checks write was performed by the prompt.
• No hard gate behavior was installed.
• No Phase 5C2 or UI cutover occurred.

First attempt note

Agent reported one earlier aborted attempt caused by a verification-side scaffolding typo. The reviewed SQL itself was not modified between attempts, and the aborted attempt rolled back cleanly. The final successful execution re-verified absence of the three target objects before re-running.

Functional interpretation

B3-F1b provides real-time soft-gate coverage for collection_registry mutations. Future INSERT/UPDATE of the 5 policy-relevant fields should run the gate and, if gaps are detected, insert deduplicated system_issues rows through the reviewed helper.

This is a soft gate only: it must never block writes. The outer function returns NEW on exception by design.

Automation caveat remains

B3-F1b alone does not fully satisfy automatic drift coverage at scale, because direct PG DDL drift may not touch collection_registry:

• rogue trigger creation on another table;
• physical table create/drop without registry mutation;
• species mapping changes without registry mutation;
• birth trigger disable/drop without registry mutation;
• function/policy changes without registry mutation.

Therefore B3-F1c/B3-HC full-scan automation remains required before declaring B3-F fully automatic.

Next action

Opus should draft B3-F1c Full-Scan Automation Design and Prompt using SHAPE_PROBE_FIRST.

B3-F1c must not assume pg_cron exists. It must first probe available PG-native scheduling/health-check mechanisms, including whether pg_cron is installed/available and whether existing system_health_checks infrastructure has a scheduler.
