Five manual post-window drills each re-ran the same mechanical battery by
hand: worktree/head hygiene, sorry/admit/axiom sweep, check.sh, and
check-selftest.sh. verification/drill.sh is that battery as one
deterministic script, per the estate rule that enforcement lives in
buttons, not in model quality: a degraded work window cannot fake it — it
either exits 0 or it does not. Optional --full adds extract.sh
regeneration byte-identity.
Scope: one new executable script. No proof, model, or gate files touched.
The bespoke part of the drill — fidelity review of NEWLY written specs
against their extracted and upstream ground truth — remains a
per-new-artifact duty, recorded in each artifact's commit message.
