A future operator-gated live run (the M2-analog) is fully rigged and rehearsed
OFFLINE — without one model call, without a key (S4.2-analog, parity row 21;
buildable after K5 + K7). `--live-dry-run` builds everything a real run would
(contracts fail-fast §10 → compose §5 → SDK-client construction → preflight)
and captures the run-config + preflight artifacts, then STOPS before the first
model call. The stop IS the boundary: the loop is never entered, so nothing is
spent (strictly offline, no D6 gate).
- run.py --live-dry-run: requires --outbox + --run-id (the drill's artifacts are
run_id-named), rejected fail-fast before any build. Writes a run_id-named PAIR
to the outbox:
* {run_id}-runconfig.json — comparison-protocol §4 pt 3: model-id per role the
loop calls (proposer/checker, THROUGH resolve_model — the run's own path),
profile, and every cap/parameter. Deliberately NO wall-clock date, so the
bytes stay deterministic (the run's date is stamped at report time, §4 pt 3).
* {run_id}-preflight.json — the captured preflight verdict (clear + refusals).
The drill CAPTURES the preflight result rather than gating the build on it:
exit 0 when clear (rig go-live-ready), non-zero when refused — artifacts
captured and ZERO model calls in EITHER case.
- The client is constructed (the verified key-free SDK premise) but never called;
a call-counting stand-in proves 0 calls. Bytes reuse the deterministic house
JSON writer; run_s10.py/runs/ byte-untouched.
- test_dry_run_loadbearing.py: 7 tests. TWO seams detach-proven RED — the
0-calls stop seam (neutralise the branch → falls to execute_run → the counting
client fires → red) and the capture seam (drop the writes → outbox lacks the
pair → red). Env monkeypatched so the preflight verdict is deterministic
regardless of the operator's ambient shell.
- 514→521 green, golden byte-exact, full gate clean (ruff+format+mypy strict,
24 src files). README: test-count sync ×2 + run.py drill note + load-bearing
mention. IKKE-scope (held): the actual live run (M2-analog, operator) and any
change to preflight/outbox.
