Index note

brain/routines/index.md on main is still at the initial placeholder because log PRs #9/#11/#14/#17/#19 remain open drafts. This PR backfills all confirmed prior-run entries sourced from PR descriptions. Operator should merge log PRs in order before the next run to keep the index current.
