Checkpoint - Codex FIX7 CP-06 Hash Micro-Patch

Date: 2026-06-08 Mode: READ-ONLY production; KB design artifacts only. Status: FIX7_CP06_HASH_SPEC_PATCHED_READY_FOR_T1_FINAL_SHORT_REVIEW

P-01: H04 evidence hashes dereference exact evidence_registry.artifact_sha256 columns. P-02: complete eight-key H04_SCOPE_V1 is pinned. P-03: H05/H02 membership, total orders, NULL/missing/empty rules are pinned. P-04: every extra index fails; a desired index must first become expected through a new sealed #20 manifest version.

Exactly 27 authority surfaces remain. Runtime-evidence tables: 11, non-authority. New readiness gates: zero. New hash contracts: zero. Production remained READ-ONLY.

T1 final short-review is allowed. Codex final approval, official-design promotion, implementation, Stage 2.6B, permit, REAL_RUN, and QT001 apply remain blocked.
