09 — FINAL VERDICT

Verdict

CODEX_HOLD_C1_STAGING_R2_NEEDS_FIXES_BEFORE_DRY_RUN

  • R1 injection issue fixed: YES
  • R1 SBX propagation fixed: PARTIAL — normal success yes; partial-create cleanup no
  • R1 P5 fail-open fixed: YES
  • R1 P6 false-PASS fixed: PARTIAL — fatal gate yes; required combined digest/atomicity no
  • TTL cleanup honest: YES
  • plan requires CODEX_R2_PASS: YES
  • official runtime protected: YES
  • permission for T2 to run dry-run: NO
  • ready for promotion: NO
  • ready for production: NO

Required fixes

  1. Make P1 partial creation self-cleaning or make SBX known to the plan before P1.
  2. Treat P2/final zero-DB readback as part of success; cleanup failure must exit nonzero and no success marker may precede it.
  3. Include ordered harness rows in P6 digest and make gate/digest atomic.
  4. Remove P1 --force or require active-registry/provenance equivalent to P2.
  5. Fix remote-temp tracking so EXIT cleanup actually retains created paths.
  6. Re-run static/no-write validation, refresh hashes/registry/evidence, and request R3.

Steps 0–6

0 foundations/search: complete; 1 receive: complete; 2 design/review: complete; 3 code: N/A by hard lock; 4–5 deploy/dry-run/production mutation: not performed; 6 ten KB reports uploaded/read back.

OR update not needed: findings instantiate existing fail-closed, evidence, and cleanup rules. TD/handoff mutation was not separately authorized under the read-only hard lock; blockers are fully recorded here.
