1. Command

python3 -m unittest tests.test_dryrun_snapshot_mark -v

(pytest absent; python3 -m unittest is the runner of record. No network, no DB, no PG_DSN/DATABASE_URL/DIRECTUS_URL/PGPASSWORD in env.)

2. Result — 21 / 21 PASS

Ran 21 tests in 0.008s
OK

TestGate (5/5 ok):
  region_identity_exact · gate_fails_on_sha_drift · gate_fails_on_length_drift ·
  gate_fails_on_marker_drift · missing_sentinel_fails
TestManifest (9/9 ok, over the REAL byte-faithful pinned region):

TestFailClosedSynthetic (4/4 ok):

TestNoDbImportIsolation (3/3 ok):
  module_imports_only_stdlib (AST: imports ⊆ stdlib) ·
  cli_refuses_wrong_mode (--mode cut ⇒ exit 2 REFUSED) ·
  cli_refuses_without_no_db_flags (missing --no-* ⇒ exit 2 REFUSED)
prior_state: was 7 OK / 14 ERROR (fixture absent/non-identity).
delta: the 14 previously-ERROR fixture-bound tests (TestGate 5 + TestManifest 9)
       now PASS — root cause (non-byte-faithful fixture) RESOLVED.

4. No-DB / no-side-effect proof

structural: TestNoDbImportIsolation green — AST asserts dryrun.py imports only
  stdlib (no cutter_agent/psycopg/socket/requests/sqlalchemy); CLI refuses any
  mode other than mark-manifest-only and refuses without --no-db-write/--no-cut/
  --no-verify (exit 2).
environmental: run with no DB reachable, no DSN env; build_manifest exercised
  in-memory by tests only; cutter_agent.dryrun.main NEVER invoked on the
  artifact ⇒ this is NOT the first Constitution dry-run; no out-dir artifacts.
production_touched: false ; db_write: NONE.

5. Interpretation

CI is fully green (21/21) with a byte-faithful pinned fixture (region sha == 17660443… exact), the byte-exact production module (f1f42e83…), and the GPT-ratified test artifact (454d9fc8…, unchanged). The recurring transport/identity blocker is resolved via byte-safe regeneration (doc 1). One open governance item remains: the fixture path-coupling (doc 1 §4 / doc 3) — routed to GPT, not self-decided. Commit remains separately gated.
