work_done
Investigated Gym Logger working copy per David's request; found index.html truncated/corrupted on server (98KB vs expected, no closing tags, confirmed 3x). Located last known-good backup via X-plore (David's device) at backups/70-health/apps/gym-logger/gym-logger-v5.39-07-17-26-1800.html (222KB). Verified backup integrity, restored to live index.html, re-verified post-restore (tag balance, node --check syntax, live save.php/load.php round-trip with real session data, 48 sessions through 07/18/26). Backed up both the corrupted pre-fix copy and the verified-good restored copy. Logged decision D626 with verification. Updated handoff-02.md in full. Flagged for follow-up: DEFAULTS-REG.md's Gym Logger PRIMARY APP pointer is wrong (points to stale v5.25 gym-logger-CURRENT.html, not the real live index.html); BUILD-DIARY.md stale since 07/13/26; v5.40/v5.41 changes not yet recovered.
