Governance Addendum — FIX7 P0 Production-Rehearsal-Only Rollback (2026-06-12)
Governance Addendum — FIX7 P0 Production-REHEARSAL-ONLY Rollback (2026-06-12)
Standalone addendum. APPLY_NOW=NO. No canonical fold. Authorizes nothing in production.
This addendum registers the objects produced by the production-rehearsal-only rollback lane. They are allocated strictly above the current known ceiling 484 (TKT-OBJ-462..484 were reserved by the prior production-readiness surface-scoping addendum; canonical body max is 461). The canonical registry JSON (rev24), registry MD (rev24), and 00-index (rev116) are not modified by this lane.
| object | title | apply_now |
|---|---|---|
| TKT-OBJ-485 | Production-rehearsal-only rollback report (md) | NO |
| TKT-OBJ-486 | Production-rehearsal-only rollback report (json) | NO |
| TKT-OBJ-487 | Evidence packet (tree 7a9364c5…7bd847f9, 23 files) |
NO |
| TKT-OBJ-488 | rehearsal-target-lock.json (isolation proof) | NO |
| TKT-OBJ-489 | clone-rollback-evidence.json + rollback-recovery-proof.json | NO |
| TKT-OBJ-490 | hardened-validator-result.json (selftest+rehearsal+negative control) | NO |
| TKT-OBJ-491 | rehearsal-bad-input-probes.json (10/10 fail-closed) | NO |
| TKT-OBJ-492 | ci-unknown-resolution.json (classified) | NO |
| TKT-OBJ-493 | updated-production-blocker-map.json (7 OPEN; rollback partially discharged) | NO |
| TKT-OBJ-494 | owner/GPT production decision packet after rehearsal (md) | NO |
Collision check: ids 485..494 disjoint from canonical (≤461) and from reserved 462..484; 0 dup,
0 orphan; registered_via_addendum=true, canonical_fold_applied=false (validated by
hardened_dryrun_validator.check_governance → PASS).
Scope: No production mutation, REAL_RUN, QT001/apply, permit/activation/repoint/cutover, CI/deploy trigger, secrets change, P7-pin edit, or canonical fold. Folding 462..484 and 485..494 into the canonical registry remains a separate owner/GPT action.
