Record monotone fill-timing gradient, live [1.57,1.77] bracket, recover-flag
interpretation, gap-cap as third tail-trim, and pre-scheduler ops checklist.
Document Phase A (max-hold/vol/corr closed; next-open as decision baseline).
Add stale_close and next_open gap-cap fill modes plus a small matrix to test
whether near-close scheduling recovers overnight momentum drift.
