Current State — FIX7 P0 Production-REHEARSAL-ONLY Rollback (2026-06-12)

Status: FIX7_P0_PRODUCTION_REHEARSAL_ONLY_ROLLBACK_READY Host: T1 OR T2 / CLEAN TERMINAL · Authority: REHEARSAL-ONLY (not production authority) Delegation consumed: AUTHORIZE_PRODUCTION_REHEARSAL_ONLY Production mutation: NO · REAL_RUN/QT001/cutover: NO · CI/deploy trigger: NO · secrets: NO

On 2026-06-12, under the GPT-delegated owner decision AUTHORIZE_PRODUCTION_REHEARSAL_ONLY, a production-like rollback rehearsal was executed on an isolated local clone only. No production surface was touched and no live system was contacted.

What was proven (clone only)

Isolated clone (/private/tmp mktemp sqlite birth_registry + executor model): PROVEN_ISOLATED_NOT_PRODUCTION (no PG/Directus/system_issues/registry/VPS/network contact).
Rollback PROVEN_IN_STAGING on the clone via two paths — transactional BEGIN..INSERT..ROLLBACK and committed-insert + snapshot-restore — each with after_apply_hash != before_hash (real mutation) and after_rollback_hash == before_hash (exact restore), rows before==after.
Hardened validator (byte-exact canonical e6547e69…956c47): --selftest PASS, rehearsal evidence PASS, fabricated no-mutation entry fails closed.
Bad-input probes 10/10 fail closed, control allowed, no PRODUCTION_PASS/REAL_RUN_PASS/ CUTOVER_PASS/seal-like token leaked.
CI UNKNOWN (FIX7 seal-vs-bytes gate) classified — not yet designed → unresolvable read-only; remains FIX7-P0-PROD-CI-SCOPE-1; does not affect clone-rehearsal safety.
Forbidden surfaces 13/13 untouched / not-requested.

Report (md+json), decision packet …-owner-gpt-production-decision-packet-after-rehearsal-2026-06-12.md, checkpoint, this current-state, governance addendum.

Production status

BLOCKED — 7 OPEN. FIX7-P0-DRYRUN-PROD-ROLLBACK-1 is partially discharged (clone-rehearsal leg proven; production leg still OPEN — needs operator-provided production-shaped DB dump clone + production OPT-4 + distinct production-rollback grant). The rehearsal-only grant does not extend to production. Default HOLD_PRODUCTION.

Governance

TKT-OBJ-485..494 reserved via standalone addendum, APPLY_NOW=NO, above ceiling 484; canonical registry JSON rev24 / MD rev24 / 00-index rev116 untouched; canonical body max remains 461.

Lineage

Consumes option 2 of fix7-p0-owner-gpt-production-decision-packet-2026-06-12.md; continues FIX7_P0_PRODUCTION_READINESS_SURFACE_SCOPING_READY. P7 does not authorize production; a rehearsal does not authorize production execution.
