1. Verdict

code_authoring_package: COMPLETE (6 docs)
entrypoint_code: AUTHORED + locally unit-tested (21/21 PASS) in shredded scratch
patch_form: PURE ADDITION — 2 new files; 0 existing files modified
applied_to_repo: NO ; committed: NO ; deployed: NO
first_constitution_dryrun: NOT executed (separately gated)
overall_status: CODE_AUTHORED_AND_VALIDATED__AWAITING_GPT_REVIEW

2. Git status (QG8)

repo: /Users/nmhuyen/iu-cutter-build/repo/iu-cutter
git_state: NOT a git repository (`git rev-parse --is-inside-work-tree` =>
  "fatal: not a git repository"; no .git up-tree). Therefore: no branch created,
  no commit, no stash, no tag.
real_working_tree_modification: NONE. Confirmed post-phase:
  `ls cutter_agent/dryrun.py` => "No such file or directory" (the new module
  exists ONLY as the KB patch in doc 2; it was authored/tested in a separate
  ephemeral /tmp scratch which has been shredded).
files_changed_in_real_repo: 0
commit/deploy performed: NO (GPT preference honored: "do not commit; provide
  patch/diff; if working tree modified report it" — working tree was NOT modified).
delivered_artifact: new-file patch embedded in KB doc 2

3. Implementation requirements coverage

1 snapshot_gate          : DONE — extract_region()+snapshot_gate(); sha/len/markers
                           rehash BEFORE parse; mismatch => FailClosed (ABORT)
2 deterministic matchers : DONE — zone_router, parse_nguyen_tac,

4. Quality-gate self-check

QG1 pinned snapshot identity : PASS — gate binds region sha 17660443…cae80c /
      len 17522 / markers ✅19📋1📝1⛔1; ABORT before parse on drift
QG2 3 ratified levels, DIEU floor : PASS — emits NGUYEN_TAC+KIEN_TRUC_SECTION+
      DIEU; no sub-DIEU fragmentation (OD-G3 implemented exactly)
QG3 deterministic matchers   : PASS — 6 matchers implemented + unit-tested
QG4 status cascade           : PASS — 3-tier; Đ44 tier_2 override EXCLUDED;
      no silent drop (coverage + reconstruction proofs)
QG5 artifact-only / no-DB    : PASS — stdlib-only (AST-asserted); flag/scope/
      DB-env refusals; db_write=NONE
QG6 first dry-run NOT executed : PASS — never invoked to emit KB artifacts;
      PASS path only exercised in-memory in scratch (now shredded)
QG7 patch/diff or BLOCKED explicit : PASS — full new-file patch in doc 2
      (not a BLOCKED-only draft); applied=false
QG8 report git status, no commit/deploy : PASS — §2 (not a git repo; working
      tree unmodified; no commit/deploy)
QG9 stop after 6 files       : PASS — exactly 6 docs; STOP → GPT/User

5. What was grounded (KB SSOT, read-only)

read:
  - GPT ruling + code-authoring approval (OD-G3 = emit 3 levels, DIEU floor)
  - the GPT-PASSed entrypoint design package (frozen input spec, 5 docs)
  - first-dryrun-planning GPT review (still-forbidden list, entrypoint contract)
  - source-seed-from-snapshot production closeout (B5/B6/SC3 CLOSED)
  - parser reference implementation draft rev3 (refimpl.r1 D-* + D-SENTINEL)
  - the pinned normalized snapshot artifact 17660443e0f23e99 (full region)
  - read-only iu-cutter repo inspection (cli.py/__init__.py/phases.py/
    canonicalization.py/signal.py + tests layout) — gap R9 confirmed
no_live_DB_SELECT / no_live_code_change: KB is SSOT; repo touched read-only only

6. Implementation recommendation (next phase — GPT/User decision)

recommended_next:
  A GPT review of this code-authoring package (doc 2 patch vs design + OD-G3)
  B if accepted: open a SEPARATE, explicitly-authorized phase to APPLY + commit
    the additive patch into the iu-cutter repo (+ CI of the unit suite). git
    commit/deploy is requested THERE, not taken now.
  C then an execution command-review + (separately authorized) the FIRST
    Constitution dry-run using the exact command in doc 4
sequencing: review(this) -> apply+commit(separate, gated) ->
  first-dryrun authorization(separate, gated) -> dry-run execution
not_recommended: running the first dry-run now (premature; gated; would be the
  forbidden milestone). No self-advance.

7. Explicit non-execution statement

• No first Constitution dry-run executed. No CUT. No VERIFY. No production IU. No production DB write. No source_document/source_version mutation. No schema change. No Directus/vector mutation. No deploy/restart. No git commit; the real iu-cutter working tree was never modified (the new module exists only as the KB patch in doc 2). No live DB SELECT. No self-advance.
• Local unit tests ran only in an ephemeral /tmp scratch (no DB, no network), which has been shredded.
• Exactly 6 docs authored under knowledge/dev/laws/dieu44-trien-khai/v0.5-constitution-snapshot-source-mark-dryrun-entrypoint-code-authoring/.
• doc 6 of 6 — STOP. Route to GPT / User review. Self-advance PROHIBITED.

8. Approval request

asking_GPT_User_to:
  - accept the authored no-DB-write entrypoint patch (doc 2) vs design + OD-G3
  - decide whether a later phase may apply + commit + CI the additive patch
  - decide whether/when the first Constitution dry-run may run (doc 4 command)
NOT asking for: authorization already exercised. Nothing here self-advances.
