TASKGATE false-positived to SOP-HEALTH-LOG.md (gym profile/dual-write, unrelated topic -- flagged as false positive rather than followed). Wrote a real SOP documenting: where the source zip lives, the 15 existing domain entries by category/id, what's deliberately NOT backfilled and why (AI diary, 90-entry backup log, blank questionnaire, empty archive index), and a repeatable 8-step process for backfilling future old-zip finds. Added to SOP-INDEX.md.
