USR369 confirmed the dropzone deliverables (EXEC_OPEN Series R zip, Server audit deliverables) were already picked up -- retired both, preserved to Trash. Retired the 'claude code' folder (4 files) -- confirmed stale via content read: a one-month-old snapshot of Master[10]'s setup (Series M, 07/30/26), long superseded by current Series T. Consolidated backend/369's own internal Trash/ subfolder (27 files -- old EXEC_OPEN D-series files, a GymLogger test artifact, old Series E/F zips) into the platform-wide Trash/ convention, since having two separate 'Trash' locations was itself part of the confusion. All content copied server-side and verified before any live file was cleared. USR369's personal space (user369_space/ -- computer, electronics, personal.db with 75 real rows) confirmed completely untouched and separate from all of this -- explicitly checked and confirmed live before and after.
