1. Outcome (PASS criterion met)

W-3 DB-isolated writer: BUILT, TESTED, SCRATCH-DRY-RUN PASS, COMMITTED (feature branch).

  commit f0120ac018b8942fdafaf105923b0e6f8dba6b40 (parent d66a60d; main 4367c83 UNCHANGED)
  targeted suite 22/22 GREEN; MARK 21/21; cutplan 15/15; discover 150/1 (pre-existing
  baseline only, R1 precedent). Scratch birth-gate dry-run: 60 IU + 60 unit_version +
  60 anchors, 0 preexisting, idempotent no-op, L1+L2 pass ×60, writer_digest d99a31d4….
  All VW-1..VW-10 PASS in isolation; all-or-nothing rollback proven.

2. Macro-goal questions answered

repo/branch/HEAD: /Users/nmhuyen/iu-cutter-build/repo/iu-cutter ·
  feature/constitution-snapshot-mark-dryrun · HEAD now f0120ac (was d66a60d)
working tree: clean before+after; only the 2 new W-3 files committed; main untouched
writer module: cutter_agent/cutwrite.py (import-isolated; no production DB; in-memory
  faithful birth-gate harness); tests/test_cutwrite_snapshot.py (22)
60 IU + 60 unit_version + 60 anchors: PROVEN in scratch (exit 0 PASS)
canonical_address uniqueness: enforced (UNIQUE backstop; 0 collision)
idempotency/pre-existence: OD-1 key + pre-existence + G-CUT-ONCE NOOP path
source_version & digest enforced: file sha 7d56f3ce…/digest 9d908a62…/self-digest/count 60
body span hash: sha256(body)==span_sha256 fail-closed ×60 (run PASSed)
Điều 44/draft/obsolete excluded: hard reject of number==44 / non-enacted candidate
parent/container (OD-W3): address-path; flat ICX-CONST/<seg> ⇒ all 60 top-level NULL
fail-closed on mismatch: exit 2 (guards) / exit 3 (manifest/region/body/birth-gate)
no production DB / no production IU / no CUT / no VERIFY: CONFIRMED (net-zero)
rollback/cleanup of scratch: PASS (rm -rf; all-or-nothing txn proven)

3. Quality gates

QG1 repo/code state reconstructed                       : PASS (doc 1)
QG2 writer authored DB-isolated, import-isolated         : PASS (doc 1)
QG3 tests authored + GREEN (targeted 22/22)              : PASS (doc 2)
QG4 baseline vs regression distinguished                 : PASS (doc 2 — pre-existing only)
QG5 scratch birth-gate dry-run PASS (60+60+60)           : PASS (doc 3)
QG6 verification VW-1..VW-10 + rollback proven           : PASS (doc 4)
QG7 no production mutation / no invented prod command    : PASS (§5)
QG8 next-gate readiness prepared                         : PASS (§4)
QG9 STOP after upload, route GPT/User                    : PASS (§5)

4. Readiness for the next gates

W-4 (credential / signing cycle) — READY TO OPEN:
  the writer's row contract + birth transaction are proven in isolation; W-4 builds the
  cutter_exec/cutter_verify principals + real DOT-991/992 signing and a production DB
  adapter SEPARATE from the no-DB path (writer's import isolation already enforced).
W-5 (production CUT command-review + separate explicit production-write approval) —
  prerequisites enumerated:
  - re-verify live fn_iu_birth_gate_layer1/2 + UNIQUE/FK + dot_config vocab read-only
    (drift precheck vs the 2026-05-19 capture the harness mirrors);
  - production adapter wired to the proven row mapping; separation-of-duty VERIFY
    (cutter_verify/DOT-992) per the VW plan;
  - explicit, separate production-DB-write approval; G-CUT-ONCE pre-existence on the
    live information_unit (0 ICX-CONST today — clean insert, must re-check at W-5).
note: P-track (cut-plan dry-run) already CLOSED_PASS; the writer now has an
  isolation-proven implementation. No production write occurs until W-5 approval.
