GPT Direction — After Mutation Safety Foundation PASS

Date: 2026-05-28 Reviewer: GPT Council via Web Connector fallback

Accepted state

IU_MUTATION_SAFETY_FOUNDATION_FOR_D_E_AND_F_ENABLE_LIVE_APPLY_150000X passed.

Key accepted facts:

• bounded gate protocol is live and self-tested;
• never-flip keys are protected in code;
• gate verify-closed works;
• review_decision wiring is already present in split/merge functions;
• event substrate is route-scoped and fail-closed;
• 4 Mothers remain blocked.

Scaling lesson

The macro finished in ~20m, still below the desired 45–60m. The next macro should bundle all remaining governed IU tests d/e/f-enable into a single phased suite, with strict safety gates and branch classification. The Agent should own completion and maximize all safe branches.

Next macro

IU_D_E_F_REMAINING_GOVERNED_LIVE_TEST_SUITE_250000X

Purpose:

• run the remaining IU tests d, e, and f-enable as one governed suite if safe;
• create the real test-only review_decision path for cloned test IUs;
• run compose/add/remove/reorder/split/merge on test IUs;
• register/exercise missing trigger-in/out event contracts only if route isolation is proven;
• run SQL-link enable/capture only on a test link if isolation is proven;
• close gates and verify rollback/fail-closed at the end;
• produce complete evidence and next production-hardening backlog.

Execution order inside one macro:

1. Hard Gate 0 and full baseline snapshot.
2. Test d governed structure ops on cloned test IUs.
3. Test e trigger-in/out if event/route isolation is proven.
4. Test f-enable/capture if test-link isolation is proven.
5. Cleanup/rollback/close all gates.
6. Evidence/report/backlog.

If any branch is unsafe, complete all safe branches and mark the unsafe branch PARTIAL with exact blocker and author-ready follow-up.

No 4 Mothers implementation.
