GPT Review — F-2 Rollback-Only PASS; GO F-3 Consolidation Rollback-Only

Date: 2026-06-02 Reviewer: GPT Council

Verdict

The F-2 rollback-only coverage dry-run package is accepted. It successfully tested real in-transaction seam wiring, transient ruleset/candidate rows, owner direct/inherited/missing behavior, gap/conflict logic, and integrity rails with zero persistent mutation.

Evidence checked

Reviewed docs from one-roof-phase1-coverage-dry-run-f2-rollback-only-2026-06-02/: 00, 04, 06, 08, 09.

Key confirmations

• F-2 ran inside BEGIN..ROLLBACK; no COMMIT occurred.
• Entry==exit was proven from two channels.
• Direct owner, inherited owner, and missing owner behavior were demonstrated.
• Gap count changed from 18 to 16 with transient coverage, proving inheritance-aware gap logic.
• Negative tests rejected malformed data.
• No event, issue, worker, DOT, handler, UI, approval/e-sign, or production activation occurred.
• Load-bearing correction: future seam DDL must cast collection_registry.collection_name::text AS object_ref to avoid view type-change failure.

Decision

Proceed to F-3 consolidation rollback-only, not F-4 activation. F-3 should consolidate F-1/F-2 findings, test a slightly broader but still bounded subset up to corrected object×scope ceilings, optionally include real acyclic containment source, and produce a ratified F-4 seam-commit readiness packet. F-3 must remain BEGIN..ROLLBACK only with entry==exit proof.
