1. Outcome

A_PRODUCTION_CUT_COMMAND_REVIEW_READY : NOT reached.
B_BLOCKED_WITH_EXACT_FINAL_GAP        : REACHED (honest; no fabrication).
single remaining CODE blocker: GAP-B1 — no committed production-shaped
  cutter_governance governed-ledger row-builder (leg B). ledger.py is the
  dry-run SKELETON and structurally diverges from the live 24-col
  cut_change_set (+ rich manifest_envelope/unit_block/dot_pair_signature/
  decision_backlog_*); the v0.4 trial's rich builder was never committed to
  this branch (doc 1 §2, catalog+repo+grep evidence). Cannot be fabricated.
also still required (sovereign, unchanged): GD-1 GRANT apply principal ·
  U-W4b scoped GRANT execution · C5 sovereign production-write approval.

2. Code / commit / tests

code_authored: YES — guarded leg-A production adapter, committed to the
  FEATURE branch only (no main/push/merge/tag):
  branch feature/constitution-snapshot-mark-dryrun · f0120ac → 152e7db
  + cutter_agent/prod_iu_adapter.py (b012d196…)  -- guards G1..G7, leg-A
    append-only allowlisted birth SQL, DOT-991 StubSigning + lane-overlap
    invariants, single-txn seam, leg-B fail-closed (LegBUnavailable/GAP-B1)
  + cutter_agent/cutprod.py (cb745473…)          -- thin composer; plan-only
    works no-DB; --mode production fail-closes exit 3 (GAP-B1)
  + tests/test_prod_iu_adapter.py (221be6dd…)    -- 20 tests
  cutwrite.py byte-UNCHANGED 31ce88dc… (ratified factory reused, not edited)
  reversible: git reset --hard f0120ac
tests_run (local, this phase, NO DB):
  NEW tests.test_prod_iu_adapter            : 20/20 PASS
  REGRESSION tests.test_cutwrite_snapshot   : 22/22 PASS (unchanged)
  REGRESSION tests.test_dryrun_snapshot_mark: 21/21 PASS (unchanged)
  REGRESSION tests.test_cutplan_snapshot    : 15/15 PASS (unchanged)
  total 78 green · py_compile OK · no psycopg/socket import · no DB connect
plan-only smoke: PLAN_OK iu=60 uv=60 writer_digest=d99a31d4…
  leg_a_statements=180 leg_b=GAP-B1(unavailable) production=REFUSED

3. Definition-of-done coverage (per the macro prompt)

1 credential/GRANT command-review package scoped to target : DONE (doc 2)
2 guarded production adapter ready OR exact adapter gap     : leg A READY+
  TESTED+COMMITTED ; leg B = EXACT GAP-B1 (doc 3) — satisfies "exact gap"
3 production CUT command-review package                     : DONE, runnable
  command WITHHELD w/ exact gap + UB-1/UB-2 + C5 (doc 4)
4 backup + drift precheck + verification + rollback/comp    : DONE (doc 5)
5 STOP before any production mutation                       : DONE (this report)
⇒ package complete; outcome correctly B (not A) because leg B is honestly
  uncodeable here and the runnable production command must stay WITHHELD.

4. Explicit no-mutation statement

production_mutation: NONE. No production DB write/IU · no CUT · no VERIFY ·
  no GRANT/REVOKE · no DB connection (default provider refuses; tests use a
  fake in-process connection) · no deploy/restart · no main/push/merge/tag ·
  no source/source_version mutation · no invented runnable production command ·
  no self-advance. Only mutation = 3 new files committed to the feature branch.
read-only actions: KB reads/6 uploads; PostgreSQL catalog/ACL/constraint/
  function probes (read-only role); repo reads; local net-zero test runs.

5. Shortest next step + where sovereign approval is needed

shortest_next_step (smallest, highest-leverage): a GPT/User ruling on GAP-B1:
  UB-2 (sovereign architectural decouple — first controlled constitution CUT =
  leg A under cutter_exec in one txn; governed change-set/DOT-991 sig/
  decision_backlog recorded via the ALREADY-PASSed v0.4 production path
  separately) — removes GAP-B1 from the critical path WITHOUT new blind code;
  OR UB-1 (open a separately-gated authoring+command-review cycle for a
  production-shaped leg-B row-builder bound to the live 24-col schema, with a
  scratch cutter_governance-mirror proof).
then in parallel (each its own sovereign gate): GD-1 (GRANT apply principal) →
  U-W4b (execute the doc-2 scoped GRANT) ; C5 (issue the sovereign production-
  write approval doc). After GAP-B1+GD-1+U-W4b+C5: finalize the runnable CUT
  command-review (doc 4 §2 contract) → sovereign-gated CUT → separate VERIFY.
sovereign_approval_needed_at: GAP-B1 ruling (UB-1 vs UB-2) · GD-1 · U-W4b
  execution · C5 production-write approval. None is Agent-self-advanceable.
disposition: STOP → route GPT/User.
