git log --oneline -1               →   689e53e ...    # HEAD == 689e53e

Confirmation: the pre-existing unrelated WIP (bin/dot-birth-trigger-setup, bin/dot-context-pack-build.sh, bin/dot-vector-audit, bin/dot-search-canary, specs/, …) is still uncommitted and was never staged — it is absent from git show --name-status 689e53e, and it remains in git status --short after the commit. The iu-cutter/-scoped status is empty, proving the working tree matches the commit exactly (the unittest/CLI runs below did not dirty tracked files; __pycache__/+*.pyc are covered by iu-cutter/.gitignore).

Each source/test blob extracted via git show 689e53e:<path> | sha256sum. The four primary files were independently re-hashed on the local authoring copy and on the VPS working tree — all three locations matched, proving the source quoted in §4 is byte-identical to the committed SSOT.

Append-only writer interfaces. write_cut_change_set sets verifier_signature_id=None (OD-6 comment in source). Status changes go through transition_status which is the audit invariant A-5:

CutterRuntime wires two principal-scoped adapters over one shared store (OD-3 separation of duty):

self.exec_adapter   = InMemoryDryRunAdapter(PRINCIPAL_EXEC,  self._store)
self.verify_adapter = InMemoryDryRunAdapter(PRINCIPAL_VERIFY, self._store)

mark() — idempotent on payload.idempotency_key; replay returns the existing entry (no dup). One exec_adapter.transaction().
sweep() — OD-SM-3 same-agent logged pass; writes sweep_log + history.
review() — builds manifest pair, writes review_decision; re-review sets prior_review_decision_id and stamps old row's superseded_by_review_decision_id (OD-5 append-only lineage).
cut() — guards G-CUT-APPROVED / G-CUT-DEPS / G-CUT-ONCE; signs DOT-991; verifier_signature_id left None (OD-6). One txn.
verify() — runs under verify_adapter (cutter_verify); signs DOT-992 onto verify_result; on force_fail writes a forward compensating change set + escalation entry (+ its birth history) and transitions to verify_failed_escalated. One txn.

Imports (entire file): argparse, json, sys, unittest, pathlib + cutter_agent.phases, cutter_agent.signal. No os, no network.

§5 — Security Boundary Evidence (read-only grep proofs @689e53e)

5A Forbidden client/network/env libraries — ABSENT

grep -rnE "^\s*(import|from)\s+" iu-cutter/cli.py iu-cutter/cutter_agent/ filtered against the stdlib allow-list (argparse,json,sys,unittest, hashlib,uuid,abc,contextlib,io,os,re,typing,dataclasses,pathlib + intra -package) returned zero residual lines → the runtime package imports no psycopg/psycopg2/asyncpg/sqlalchemy, no requests/httpx/ urllib, no socket, no qdrant*, no directus* client, no subprocess.

5B `os`/env/DB/network token scan — only benign name literals

grep -rn "os\.\|environ\|getenv\|psycopg\|asyncpg\|sqlalchemy\|requests\| httpx\|urllib\|socket\.\|qdrant\|directus\|psql\|subprocess" over cli.py+cutter_agent/ returned exactly two lines, both the string literal "directus"/"postgres" inside FORBIDDEN_WRITE_PRINCIPALS (__init__.py:29) and the matching docstring (db_adapter.py:10). → No os.environ/getenv anywhere in the runtime package; no DB client; no .env access; no network. (os/environ is used only in tests/test_security_boundaries.py, which strips env to prove the pipeline needs none — not part of the runtime package.)

5C Secret/DSN literals — ABSENT

grep -rniE "postgres://|pgpassword|password\s*=|secret\s*=|dsn\s*=" over cli.py+cutter_agent/ → NONE-FOUND.

5D ProductionDBAdapter refuses construction

db_adapter.py:40 class ProductionAccessNotAuthorized(AdapterError); :231 class ProductionDBAdapter(DBAdapter); :239 raise ProductionAccessNotAuthorized(...) in __init__ → any instantiation (with or without args) raises before any connect/env/DSN. Test proof in §6.

5E Principal write-guard

__init__.py:28-29 FORBIDDEN_WRITE_PRINCIPALS = {"cutter_ro", "workflow_admin","directus","postgres"}; db_adapter.py:57-65 _assert_writer() raises WriteForbidden for any forbidden principal and for any principal not in {cutter_exec,cutter_verify}; _assert_writer() is invoked from insert()/cas_status()/ stamp_superseded() (:94,:100,:111). Test proof in §6.

5F CLI `--production` refusal

cli.py:33 _refuse_production() → writes refusal to stderr, :43 return 2; :77-78 if args.production: return _refuse_production(). Runtime proof in §6 (rc=2).

§6 — Behavior / Test Evidence

6A unittest — VPS Python 3.12.3 (`cd /opt/incomex/dot && python3 -m unittest discover -s iu-cutter/tests`)

.............................................
----------------------------------------------------------------------
Ran 45 tests in 0.012s

OK

Verbose run: 45 ok lines (45/45 pass, 0 fail, 0 error).

6B unittest — local Python 3.11.6 parity

Ran 45 tests in 0.003s
OK

→ 45/45 on 3.11 and 3.12 (cross-version parity).

6C CLI demo (dry-run pipeline)

{ "committed_txns": 5, "entry_id": "<uuid>",
  "final_status": "verified_complete", "production_touched": false,
  "tables": { "cut_change_set":1,"cut_change_set_affected_row":1,
    "decision_backlog_entry":1,"decision_backlog_history":5,
    "decision_backlog_sweep_log":1,"dot_pair_signature":2,
    "manifest_envelope":1,"manifest_unit_block":1,"review_decision":1,
    "verify_result":1 } }

MARK→sweep→REVIEW→CUT→VERIFY → verified_complete; exactly 5 atomic phase transactions; in-memory ledger only; production_touched=false.

6D CLI `--production` refused

REFUSED: production mode is NOT authorized in the v0.4 code-authoring cycle.
... (separately-gated future cycle ...)
rc=2

def test_success_is_hard_terminal(self): ... S_VERIFIED_COMPLETE -> * raises
def test_failed_cannot_become_success(self):
    ... S_VERIFY_FAILED_ESCALATED -> S_VERIFIED_COMPLETE raises

(Valid-path test test_happy_path_chain_is_allowed walks BIRTH→marked→ review_pending→reviewed_approved→cut_applied→verified_complete with no exception.) All pass within the 45/45.

No defect was encountered while collecting evidence; no STOP condition was triggered; no revision cycle is requested.

§8 — Verdict / Limitations Carried Forward

evidence_supports_final_gpt_code_PASS: YES (in this Agent's assessment;
  final verdict is GPT's)
  basis:
    - SSOT commit 689e53e: 16 files, 1821 insertions, all under iu-cutter/,
      unrelated WIP provably untouched/uncommitted
    - source quoted == committed blob (SHA-256 manifest, tri-location match)
    - 45/45 stdlib unittest PASS on VPS py3.12 AND local py3.11
    - all 10 GPT-ratified ODs evidenced in source + tests (OD-1 scenario_ref
      excluded, OD-2 alias-free, OD-3 two principals, OD-4 local signal,
      OD-5 append-only chain, OD-6 verifier_sig NULL at CUT, OD-SM-1 CAS,
      OD-SM-2 S5/S7 non-persistable, OD-SM-3 logged sweep)
    - security boundary proven by grep + runtime tests: no DB/net/env/secret
      libs, ProductionDBAdapter refuses, principal guard, --production rc2
limitations_carried_forward (unchanged from code-authoring report; design-scoped):
  - in-memory storage only; no real DB adapter (deferred, separate cycle)
  - canonicalization + signing are deferred HIGH-risk placeholders; Stub
    signing is non-cryptographic (is_production=False)
  - dry-run lineage uses helper field review_decision._source_entry — a
    real schema-backed adapter must map via manifest/source columns
  - composite PK / full FK graph modelled loosely (dict), not PG-enforced
  - single-process CAS; multi-writer race is a dry-run-cycle concern (OD-SM-1)
  - signal source local/test only (OD-4)
gates_still_closed:
  ready_for_credential_cycle: NO
  ready_for_dry_run: NO
  ready_for_production_CUT_VERIFY: NO
the_only_next_thing: GPT final code review using this evidence package
agent_self_advance: PROHIBITED
