10 — FINAL DECISION

Verdict

C1_STAGING_CODEX_R3_FIXES_READY_FOR_CODEX_R4

Final report checklist

• verdict: C1_STAGING_CODEX_R3_FIXES_READY_FOR_CODEX_R4
• Claude found additional defect during self-review: YES — (1) OR/jsonb_array_length non-short-circuit reliance (mitigated via CASE guards in new P6 code; existing trigger proven to work on PG16.13 so left byte-identical); (2) duplicate-key JSON forgery (escaping, not just jq-verify, required); (3) psql interpolation gotcha (proven inert inside quotes). See 08.

• P3/P4/P5 DONE atomicity proof: gate<DONE<COMMIT, no pre-gate COMMIT (03, 05).
• P6 independent verification proof: exact set + invariants + own-oracle (stored pass not trusted) + sandbox-matched stamps + 42P01 + 0 orphan; 1 GOOD + 6 TAMPERED fixtures validated read-only (04).
• P6 digest source proof: spans vocab(+P4 evidence) + harness + stamps; computed post-gate, in-txn, persisted-then-readback (06).
• static/no-write validation summary: bash -n 8/8; shellcheck rc=0; guard 9/9; sha256 19/19; registry integrity 18/18; jq present; stg_ledger fail-closed; psql interpolation safe (07).

• dry-run executed: NO
• staging DB created: NO
• ready for Codex R4 review: YES
• ready to run dry-run without Codex: NO
• ready for promotion: NO

Boundaries reaffirmed

Mutation confined to /opt/incomex/staging/c1/. No official dot_tools/CAT-006/dot_agent_api_contract change. No APR-0415 approve/execute. No dot-apr-approve. No promotion. Teardown remains rm -rf /opt/incomex/staging/c1 (official runtime untouched).
