First application of Tech[30]'s new SOP-HANDOFF-HYGIENE.md (03A_CONFIG note: read the SOP in full first per USR369's direct instruction). Verified every item in the accumulated handoff (multiple shrink-guard-preserved layers dating to 08/25) against the live decisions table (1,022 records queried, not assumed) before dropping anything -- confirmed the "Work Done 1-21" narrative, SESSION SUMMARY, DECISIONS MADE THIS SESSION list, and SESSION CONTINUATION block were all individually logged (D783-D929 range) before removing them. Confirmed the one ACTIVE WORK item (TASKGATE sop_scope bug) was already fixed by Master (D887, same root cause, verified live 08/26) before dropping it. Presented the full prune plan to USR369 for confirmation before writing (per the SOP's explicit statement that it does not bypass NO-SELF-FORCING) -- USR369 confirmed. Wrote with overwrite_confirm=1. Preserved OPEN TASKS (T84-T65) verbatim, unchanged. Added the one genuinely new open item (backend restructuring scope question) and carried forward T-ZIPSEARCH-BROADQUERY as the one real unresolved technical thread.
