/**
 * Hook: PostToolUse — pairs the parked before-state with the result and writes
 * the ledger entry.
 *
 * Only a call that actually landed reaches this event, so every entry written
 * here is an applied one. A denied or failed call fires the snapshot half and
 * never this one, leaving its snapshot unclaimed — which is why claiming also
 * reaps the ones that were abandoned.
 *
 * Silent and fail-open, for the same reason as its other half.
