Credibility pass: the collapse loses its scaffolding

Blind reviews over the rev-37..40 features and the gate collapse. The
scripted surgery's scars come out: bare brace blocks unwrapped (with one
hiding an unreachable scrambleHands), the amputated comment healed, the
dead events parameter unthreaded from the illusion-sight chain, the
laziness probe in perceivedBoard collapsed to the rule it always produced,
GameView.deckRev retired with its last reader, the ward's arming stub
told honestly, and every comment or test title still citing the retired
revision numbering reworded to the rule it guards. Rim mechanics unify on
rimWarpMouth and breachRim; the test suite gains plainRimWall and
pushSustained and loses its loop-shaped scars and rev-named helpers.
No behavior changes; 255 tests pass unchanged.
