Checkpoint - Codex Stage 2 QT-001 Backfill Apply Readiness Review

Date: 2026-06-06 Status: NOT_SAFE_NEEDS_FIX Mode: READ-ONLY production audit; report files only.

The exact five-target 137-row batch is valid, but must not be applied because the apply DOT source is pseudocode and readiness/permit/ledger controls can false-pass or false-complete.

Evidence: required=74; resolvable=70; unclassified=4; preflight PASS=68/no_table=2/unclassified=4; target delta=137; target births=8; QT001-origin births=0; open permits=0; ledger planned=5/137/done=0; new QT001 procedures=0; new DOT rows=0; gateway 5/5 OK; old dangerous DOTs frozen 2/2; managed truth=2,930; raw noise=98.96%.

Exact blocker: 05_dot_birth_qt001_apply_SOURCE.sql contains only a commented pseudocode loop, then writes ledger done while counters remain zero.

MCP read-back PASS: all 10 canonical docs listed and vector search returns this checkpoint. Final no-worse after 12 authorized report uploads: birth_registry=1,210,896 (+12 knowledge_documents); target births=8; target QT001 births=0; open permits=0; done ledgers=0; gateway=5/5 OK.

Next macro: BIRTH_STAGE2_QT001_APPLY_DOT_HARDEN_AND_INDEPENDENT_REAUDIT. Do not open permits or apply before fresh review.
