1) K-GYM-01: root-caused and fixed the AND-gate bug (hasDraft() && savedHdr) that destructively wiped session data on refresh after loading from History -- changed to OR-gate, verified live. 2) K-GYM-02/03/04: found additional fixes already present in the working file mid-session with no traceable authoring call, flagged the anomaly to USR369 rather than silently accept, reviewed each fix line-by-line before trusting, deployed after confirming correctness (KEEP checkbox now syncs to server, fixed a double-? malformed URL bug, sync no longer disables permanently on one failure). 3) K-GYM-05: investigated a reported DLM profile timeout directly via a live diagnostic script against gym.db -- proved query is instant (0.3-0.7ms), retracted the earlier Server[40] escalation with a correction. 4) T-GYM-UI-01/02/03: removed unused Hide Done/Compact buttons per USR369; fixed exercise dropdown placeholder duplicating the row header text; corrected the color-distinction fix after USR369 confirmed v5.45's text-color approach was not visible on device, switched to a border+background approach for cross-browser reliability. 5) T480 deep investigation: confirmed 70-app.db (normalized weight x reps schema) and gym.db (JSON blob, free-text sets including narrative cardio/pool entries) are fundamentally incompatible in shape, not just sync-staleness -- a naive sync would corrupt or drop cardio/pool session data. Presented two real fix options to USR369 (rebuild sync with lossy handling vs. have Health read gym.db live). USR369's reply referenced T2528, which is assigned to Tech[30] not Builder -- flagged as a likely mismatched code. Session closed before T480's actual fix direction was decided.
