WO-3c: Delete dead non-NOT_READY retry block (~100 LOC). The block declared retry_count = 0 inside the per-iteration Err arm, so the 'MAX_NON_NOT_READY_RETRIES=3' budget actually fired exactly once (1s pause + 1 retry) before falling through to NonTrimmed. The 'exponential backoff: 2s, 4s, 8s' comment was wrong by construction. Cross-pass NonTrimmed retry (each pass gives the same sectors another shot) already covers the recovery case, and gives the drive minutes between attempts instead of 1-8 seconds — empirically what stochastic recovery on the BU40N actually needs. WO-4 (targeted slice): Add wedge-family cooldown on HARDWARE_ERROR / ILLEGAL_REQUEST senses. These are what the BU40N's firmware fast-fail state returns; every subsequent read in that state comes back in <100ms. Pre-fix patch hammered the drive: mark NonTrimmed, sleep 1s, advance, hit next wedge, mark, sleep 1s — exactly the rapid-retry cadence the firmware is sensitive to. Now a wedge-family sense triggers WEDGE_FAMILY_COOLDOWN_SECS=30 cooldown (matches read_error.rs's ZONE_ENTRY_COOLDOWN_SECS), and WEDGE_ABORT_THRESHOLD=16 consecutive wedges aborts the pass for autorip eject+reload. Any non-wedge read clears the counter. Also drops the duplicate NonTrimmed dispatch (Mapfile::record is idempotent so it wasn't a correctness bug, but it doubled per-failure consumer work).
