Verdict

execution_status: BLOCKED_CORRECTLY
agent_behavior: PASS_CORRECT
production_mutation: none
backup_taken: false
DML_started: false
rollback_needed: false
reason: QG1_fresh_checksum_precheck_failed

Codex followed the approved guard correctly. Because the fresh normalized checksum did not match the approved canonical checksum, it stopped before backup and before DML. This is the correct fail-closed behavior.

Accepted evidence

catalog_prechecks:
  P1_target: PASS
  P2_supporting_registry_state: PASS
  P3_existing_source_rows: PASS
  command_integrity: PASS

fresh_source_checksum:
  expected_normalized_length: 17791
  actual_normalized_length: 17522
  expected_sha256: f9d22d0571fa296cbc8e308c46acde93804ffcfb4a19a2e7f55dabd8657d1689
  actual_sha256: 17660443e0f23e994e1807cf8e22920951a9e70c598956dbd0e752f4f5cae80c
  marker_counts_expected: "✅19 📋1 📝1 ⛔1"
  marker_counts_actual: "✅19 📋1 📝1 ⛔1"

The marker counts match, but normalized length and checksum differ. Therefore the source seed must remain blocked.

---

Interpretation

The current evidence does not yet prove whether the difference is:

possibilities:
  A_real_source_change:
    description: authoritative content changed since the prior canonical checksum

  B_parser_implementation_mismatch:
    description: Codex implemented the approved-in-principle normalization differently from the previous ratification run

  C_source_render_shape_change:
    description: Nuxt render changed structure/chrome and the extraction span now cuts a slightly different region

  D_tool_fetch_or_encoding_issue:
    description: fetch/encoding path differs enough to change normalized output

Because the marker counts are identical and the normalized length delta is 269 characters, parser/span mismatch or a small content/render shape change is plausible. Do not update the canonical checksum silently.

---

Ruling

source_document_seed_execution: REMAINS_BLOCKED
approved_canonical_checksum: not_updated
new_actual_checksum: not_approved
next_phase_required: checksum_diff_triage

No seed execution is authorized until the mismatch is explained and either:

resolution_paths:
  path_1_parser_mismatch:
    action: fix/ratify exact parser implementation and rerun confirmation

  path_2_real_content_change:
    action: author a new source version candidate/checksum package and request GPT approval

  path_3_render_shape_change:
    action: amend parser profile extraction rule, rerun confirmation

---

Required next phase

Open a narrow read-only triage phase:

next_phase: v0_5_constitution_checksum_mismatch_diff_triage
nature: read_only_debug_and_design__no_seed_no_dml

Purpose:

purpose:
  - reproduce current normalized output using Codex path
  - recover prior canonical normalized output or regenerate it using the prior approved rules if possible
  - diff expected vs actual normalized content
  - identify whether 269-character delta is content change, parser mismatch, render shape drift, or encoding issue
  - recommend whether B6 remains closed, reopens, or needs amended parser profile

Still forbidden

still_forbidden:
  - source_document INSERT
  - source_document_version INSERT
  - DML execution
  - backup/DML retry for same seed package
  - silently update canonical checksum
  - Constitution dry-run
  - CUT
  - VERIFY
  - schema change
  - GRANT/REVOKE
  - index DDL execution
  - Directus mutation
  - deploy/restart
  - git commit
  - self-advance to source seed execution

Final status
