pbsdrProvisionAtom, on tenantsync token_exists: consult the customer's MOST RECENT host-deletion record. escrow_acked=true -> invoke the EXISTING tenantsync Reissue op, store the audit event (pbsdr_auto_reissue, hub-source, "Previous key destroyed (acknowledged deletion) - credentials re-issued automatically."), proceed to secret+descriptor as a normal provision. No record / un-acked -> the pre-existing refusal, byte-unchanged (never-silently-re-key law; operator ruling 2026-07-13). Scenario A test drives the REAL handler path over a REAL escrow-ack delete; scenario B pins the exact non-effect (zero Reissue calls, no state). Red-proof: bypassing the gate flips both B subtests to 303 (silent re-key).
