Credibility pass: the accretion sanded smooth

Blind reviews over d2b40ec..HEAD (engine / web / server+deploy). Orphaned
doc comments rejoined their functions; the swap-meet tradables collapsed
from four pasted deriveds to one (killing the "the's treasure" label);
FEAR's aura and banner now share the engine's own dreadDistance; the
long-press peek got one home; rulebook.ts stopped wearing JSON quotes;
process-named tests and war-story comments now state the constraints they
pin; the protocol doc caught up to its handlers; verify-ledgers.sh can
actually count failures; the runbook learned about the determinism gate
and the nightly backups. No behavior changes — 255 tests and all 48
production ledgers replay identically.
