USR369 asked for any housekeeping/maintenance due. CHECKPOINT was BLOCKED (handoff 24.6h stale, blocking) plus 2 non-blocking warns (LEGACY 213.8h stale, no memory-pipeline entry today). Fixed all 3: prepended fresh handoff-70.md entry summarizing this session's full old-zip backfill + SOPs + housekeeping, prepended fresh LEGACY-70.md session entry (append-only, most-recent-at-top format respected), logged memory-pipeline finding K424 (TASKGATE false-positive pattern). Also ran get_items and inbox pickup -- surfaced 7 open backlog items (2 high-priority: dental implant decision id10, medical clearance id3 -- now connectable via this session's thumb-CMC backfill; 1 needs USR369 confirmation: Medi-Cal/Covered CA status id12; 1 data-quality blank row id6 flagged not fixed). No reply yet from CC on the v6.00 followup.
