USR369 uploading legacy zips from old local systems to backups/old-zips/ (platform root, structure mirrors decade layout, upload in progress). TASKGATE returned genuine no-match for this task, per its own instruction wrote a new SOP rather than improvising. Documented the distinction between per-system archives (systems/[XX]-name/old-zips/, confirmed live for Health[70]) and the new shared consolidated one. Added entry to SOP-INDEX.md (append mode). Broadcast via COMMS action=broadcast to all systems (D671 correct mechanism, not inbox-api drop).
