Major Series S session: fixed web-fetch.php action=search (dead duplicate code, no SSH needed), fixed a platform-wide add_decision HTTP 500 bug on 9/11 systems, fixed Travel's mistagged domain table rows, closed T034/T042/T573/T720/T727/T730/T737, and built + deployed + fully live-tested a real delete/trash primitive (trash_item/restore_item/hard_delete_item) across all 11 systems' data/api.php. Updated handoff/todo/LEGACY/knowledge/ARTIFACTS mid-session ahead of this close for full continuity. No open build thread.

1) Fixed web-fetch.php action=search (T730) -- removed dead duplicate code block with a stray brace that trapped the response in an unreachable code path. 2) Wired snapshot retention into CLEANBACKUPS.php v1.1 (T727). 3) Closed T034 (jurisdiction_check gap on Builder), T042 (no-op, already built), T573 (no-op, egress confirmed fine). 4) Added disk_usage action to records-api.php (T720). 5) Found and fixed a platform-wide add_decision HTTP 500 bug on 9 of 11 systems (stray null param in PDO execute()), all backed up/syntax-checked/deployed/live-tested. 6) Closed T737 per Master's correction. 7) Fixed Travel's domain table rows 1/2 (mistagged system:10 -> 95) via a backed-up direct DB write. 8) Built T726: real trash_item/restore_item/hard_delete_item across all 11 systems, no schema migration (reused existing status column), full live test cycle (create/trash/hide/trash-view/restore/safety-gate/hard-delete) run individually on all 11 systems, zero test data left behind. 9) Updated handoff-40.md, todo-40.md, LEGACY-40.md, knowledge-40.md, ARTIFACTS-40.md for continuity ahead of this close, all backed up and verified. 10) Two genuine multi-minute platform outages hit mid-session (proxy-side per K215/K216) -- both waited out correctly, confirmed via server-check.php before resuming, no data lost.
