Hotfix: the wrap gains its vintage gate; every ledger verified

Same lesson twice in one night: the toroidal dread applied at every rev
and QD3S (recorded flat) refused seq 76 again on restore. rev >= 32
wraps; older vintages measure the flat diamond they were played under.
This time verified properly: a strict replay harness (any refused
command is a hard failure) ran all 41 production ledgers against the
new engine before deploy — 0 failures. That harness now lives in the
repo as the pre-deploy determinism check it always should have been.
