10 — Final Summary

Status: PASS. Stage 2.6A built the Plan / Tier / Independent-Review-Signoff registries as the QT-001 apply-control SSOT, classified and de-fanged the dangerous hardcode, made readiness consume the registries while staying BLOCKED, and proved the writer cannot execute on hardcoded assumptions. No apply, no permit, birth-neutral except authorized report provenance.

Supertrack results

• A (hardcode inventory): 11 findings classified; 6 DANGEROUS, 2 UNKNOWN_BLOCK, 1 TEMPORARY_SENTINEL_OK, 1 METADATA_DRIVEN_OK, plus HC-11. Nothing unclassified. v_qt001_hardcode_no_go_guard.pass = true.
• B (plan registry): qt001_plan_registry + fn_qt001_build_plan_registry; first generation PLAN-20260606-093413 v1 hash f8d2272f, 13 rows, all blocked + hashed; tiers derived from data; v_qt001_plan_registry_no_go_guard.pass = true.
• C (tier registry): qt001_tier_registry, 4 tiers, all apply_allowed=false; v_qt001_tier_no_go_guard.pass = true.
• D (signoff registry): qt001_independent_review_signoff + qt001_review_validated_collection; Codex NOT_SAFE recorded as data; signoff_safe false; v_qt001_independent_review_no_go_guard.pass = true.
• E (readiness v3): v_qt001_apply_readiness_guard_v3 + dashboard; SSOT gates 4/4 green, apply gates RED; overall_ready false; cannot false-green from literals.
• F (writer blocked): enforcement contract + must-remain-blocked guard pass true; writer body unchanged.
• G (scale risk): per-collection annotation + scale_not_safe = true; carried into readiness scale gate.
• H (design/index): index rev 12 + Stage 2.6A packet.
• I (safety audit): all anchors hold; only +9 authorized KB report births.

Headline

Tiering moved from a hardcoded 5-collection IN-list in fn_qt001_refresh_plan_snapshot to a data-driven derivation (parity + validated-collection registry) and reproduces the prior classification exactly (TIER1 5/137, TIER2 2/137, TIER3 6/505). The literal independent_reaudit_signed_off=false is replaced by a signoff registry record; readiness can only green when an external reviewer records a SAFE verdict bound to the current plan checksum.

Completion contract

PASS: dangerous hardcode inventoried; plan/tier/signoff registries LIVE; readiness consumes registries and remains blocked; writer cannot execute via a hardcoded path; scale risk surfaced; no real apply occurred.

Next macro

BIRTH_STAGE2_6B_QT001_PERMIT_RUN_KEYSET_RESUME (router-selected): permit/run lifecycle binding plan checksum + watermark + exact delta; keyset/range resume + set-based plan; wire the writer to the registries (stricter, rollback-safe); parity-invariant separation (HC-05/HC-11); legacy resolver fix (HC-04) + TG_ARGV scanner (HC-07); duplicate-trigger reconciliation; paired executor/scanner DOTs + revoke PUBLIC EXECUTE; representative-volume performance gates. Then a fresh independent re-audit. Blocker: none technical — apply blocked by design + pending next layers and external re-audit; zero engineering blocker.
