FIX7 P0 - Final Pre-Real-Data Readiness Packet (2026-06-12)

Macro: FIX7_P0_FINAL_PRE_REAL_DATA_READINESS_LANE_MACRO_2026_06_12 Final status: FIX7_P0_READY_FOR_REAL_DATA_DECISION Production mutation: NO. REAL_RUN/QT001/cutover: NO. Production CI trigger: NO. Secrets change: NO. Live system contact: NO.

What this lane proved

1. Safety chain - every prior lane status and pin re-verified from governed KB bytes (safety-chain-reconstruction.json): N7/N8/P7 seal pins recomputed from source JSONs, hardened validator e6547e69..956c47 byte-exact, governance baseline rev24/rev24/rev116 byte-exact.
2. Surrogate rehearsal - no operator clone exists (re-searched), so a deterministic production-shaped SURROGATE sqlite fixture was generated from the governed surface inventory (7 modeled schema entities, marker GENERATED_SURROGATE_NOT_REAL_PRODUCTION_DUMP, db sha 5a6ad463..bcf598). The full before -> Tier-0-gated birth apply -> rollback cycle is proven: after_apply != before, after_rollback == before byte-exact, rehearsal row absent, row counts restored (surrogate-rehearsal-execution-evidence.json, rollback-evidence.json).
3. Hardened validator - canonical byte-exact copy: selftest PASS, surrogate rehearsal evidence PASS, fabricated no-mutation negative control fails closed (hardened-validator-result.json).
4. Bad inputs - 12/12 fail-closed, any_fail_open=false, no forbidden authorization token leaked (bad-input-probes.json).
5. CI gate adoption - complete off-production adoption packet published separately (tree b22c08d0..f26d63); 9/9 byte-drift tests behaved as expected (ci-seal-vs-bytes-adoption-packet.json, ci-gate-test-results.json).
6. Governance fold 462..507 APPLIED - canonical max 461 -> 507, next free 508; reverse-patch rollback proven byte-exact in staging; post-fold KB bytes verified equal to staged expectations (governance-fold-462-507-result.json).
7. Final blocker map - 7 blockers remain, ALL owner/operator/production-data decisions; 0 engineering blockers remain (final-blocker-map.json).
8. Decision packet - 5 options, default HOLD_REAL_DATA, nothing selected (final-real-data-decision-packet.md).

Rerun

bash commands.sh   # regenerate surrogate in fresh mktemp + full rehearsal +
                   # hardened validator + 12 probes; OVERALL PASS expected
bash RERUN.sh      # hash-verify packet, rerun, prove regenerated outputs
                   # byte-identical (generation is deterministic)

Boundary

The surrogate is NOT real production data and is never to be presented as such. This packet authorizes nothing: production, REAL_RUN, QT001/apply, permit/activation/repoint/cutover, and production CI wiring each remain separately gated (see final-blocker-map.json).
