1. Live repository state (reconstructed read-only, git + shasum, this session)

repo_path:        /Users/nmhuyen/iu-cutter-build/repo/iu-cutter   (git repo, confirmed)
branch:           feature/constitution-snapshot-mark-dryrun   (current)
branches:         main ; feature/constitution-snapshot-mark-dryrun
HEAD:             4367c83553207a9e3e037d6092f27a39c47eca7b
HEAD_message:     "baseline: ratified iu-cutter v0.4 skeleton before snapshot MARK entrypoint"
HEAD_unchanged:   true  (== baseline-closeout 4367c83 ; main untouched ; 1 commit total)
working_tree:     clean except 3 UNTRACKED paths (no tracked file modified/staged/committed)
untracked:
  - cutter_agent/dryrun.py
  - tests/test_dryrun_snapshot_mark.py
  - tests/fixtures/                       (dir; 1 file inside)
tracked_files:    17 (KB-SSOT v0.4 skeleton; unchanged)
python:           3.11.6 ; pytest absent (runner = python3 -m unittest)

2. Byte-state of the three untracked artifacts

cutter_agent/dryrun.py:
  size_lines:   558
  sha256:       f1f42e83ca23ba0b328f79cf04a8391ac699d1b307eb1b22b52c305f2efa1422
  vs_KB_doc2:   EXACT MATCH  (declared module_sha256 f1f42e83…2efa1422)
  status:       BYTE-EXACT — ACCEPTED (GPT: implementation_module ACCEPTED_BYTE_EXACT)

tests/test_dryrun_snapshot_mark.py:
  size_lines:   219
  sha256:       454d9fc84e940fdcf9da10bf29d12c5c420e21b1147ccc8da6a29a81f2843a4a
  KB_declared:  31143968f322433cc5da62fa3ccf2a1fbe1905f461940c789a57cb0a116dc1b4
  status:       SHA MISMATCH (454d9fc8 ≠ 31143968) — KB-authoring transport artifact;
                line-for-line ≡ KB doc-2 verbatim block; 31143968 NOT byte-recoverable

tests/fixtures/constitution-normalized-17660443e0f23e99.md:
  whole_file_sha256: b2241dc60b3e6c3791284ea0daf5f30997951f65c321679d4971ef43ff0f8552
  region_via_D.extract_region:
    region_length: 17522            == pinned 17522  ✓
    region_sha256: 86d6aea7539d006f3e3af35b784b2599ff6dc6f330607939e4d86bde53097550
    pinned_sha256: 17660443e0f23e994e1807cf8e22920951a9e70c598956dbd0e752f4f5cae80c
    IDENTITY:      FALSE (86d6aea7 ≠ 17660443) — NON-IDENTITY fixture, confirmed live
  marker_counts: {enacted:19, controlled_draft:1, draft:1, obsolete:1}  == pinned ✓
  is_NFC:        true ; codepoint substitution class: U+2013 EN-DASH ×3 (length invariant)

Re-verified this session: independent hashlib/unicodedata recompute reproduces 86d6aea7 (len 17522) for the fixture region — exactly the KB-recorded non-identity hash. No Unicode normal form (NFC/NFD/NFKC/NFKD) recovers 17660443. State is fully consistent with the prior BLOCKED package; nothing drifted.

3. Test execution (read-only python3 -m unittest, observed this session)

command:  python3 -m unittest tests.test_dryrun_snapshot_mark -v
result:   Ran 21 tests — FAILED (errors=14)   [process exit 0; unittest reports FAILED]
OK:       7   = TestFailClosedSynthetic (4) + TestNoDbImportIsolation (3)
ERROR:    14  = TestGate (5) + TestManifest (9)
error_cause: FileNotFoundError on
  /Users/nmhuyen/iu-cutter-build/repo/iu-cutter/constitution-normalized-17660443e0f23e99.md
  (test resolves ART = parents[1] / "constitution-…md" i.e. REPO ROOT;
   the provisioned fixture lives at tests/fixtures/ — PATH MISMATCH;
   AND even if path-resolved, region sha 86d6aea7 ≠ 17660443 ⇒ snapshot_gate
   would FailClosed. Two independent reasons the 14 fail.)
non_fixture_subset: 7/7 PASS (regression-clean vs byte-exact dryrun.py)

Note (precise): the 14 failures are currently path-bound (root path absent by design — quarantine to avoid a misleading run), with a latent identity-bound failure behind it (non-identity fixture). Both must be resolved for green CI.

4. Production / safety status

production_touched:        false
db_write:                  NONE  (no DB reachable/used; module is stdlib-only, AST-isolated)
first_constitution_dryrun: NOT executed (cutter_agent.dryrun.main never invoked on artifact)
CUT / VERIFY:              NONE
source_document/version:   UNCHANGED
schema / Directus / vector:UNCHANGED
commit / deploy / push:    NONE (HEAD 4367c83, main untouched)
reversibility:             full — delete 3 untracked paths ⇒ identical to baseline
this_session_actions:      read-only git/shasum, KB reads, in-memory hash recompute.
                           NO file written/edited in repo. QG1 (no mutation) HONORED.

5. Foundations already CLOSED (per KB SSOT — context, not re-verified here)

                   CP-7 rehash PASSED at capture — artifact was byte-correct WHEN WRITTEN)
