FIX7 P0 — Execution-Readiness Review Packet (2026-06-11)

• Authority: DRYRUN_NON_AUTHORITY. Machine form (byte-identical): fix7-p0-execution-readiness-review-packet-2026-06-11.json = packet execution-readiness-review.json.

Verdict: READY_FOR_OWNER_EXECUTION_REVIEW

The staging/temp dry-run passed, rollback was proven in staging, the packet passes TKT Base L0–L3, and the KB round-trip is byte-exact. The only remaining blockers are owner/ operator execution decisions and production scoping — no engineering or environment blocker remains for the dry-run lane.

dimension	value
production_ready	false
implementation_execution_authorized	false
production_rollback_proven	false
dryrun_executed	true
rollback_proven_in_staging	true
tkt_base_level_reached	L3
bad_input_any_fail_open	false
kb_reconstruct_byte_exact	true
REAL_RUN / QT001 / permit / activation / repoint / cutover	NOT_REQUESTED

What the next macro may do (only if owner authorizes)

AUTHORIZE_IMPLEMENTATION_EXECUTION_NO_PRODUCTION (KB/governance surfaces only, every mutation gated + rollback-verified) — and only after owner OPT-4 (FIX7-P0-PLAN-EXEC-AUTH-1) and production-surface scoping (FIX7-P0-PLAN-SURFACE-1/2). REAL_RUN / QT001 / permit / activation / repoint / cutover / any production mutation each still require their own separate explicit authorization.

Must stop at a true blocker if

Owner does not give OPT-4, or the production birth surface cannot be scoped without touching production. Neither condition is resolved by this dry-run.

Remaining blockers

FIX7-P0-PLAN-EXEC-AUTH-1 (owner OPT-4) · FIX7-P0-PLAN-SURFACE-1 (production birth surface UNKNOWN) · FIX7-P0-PLAN-SURFACE-2 (CI surface UNKNOWN) · FIX7-P0-PLAN-REALRUN-1 (REAL_RUN) · FIX7-P0-PLAN-SEPARATE-AUTH-1 (QT001/cutover) · FIX7-P0-DRYRUN-PROD-ROLLBACK-1 (production rollback proof needs a separately-authorized production phase).

engineering_remaining = none (dry-run lane). environment_blocker = none for the staging dry-run (local /tmp sufficient); a production-equivalent staging environment is required only for a future production-class rehearsal, not for this KB/governance dry-run.
