GPT-5.5 Commits Evidence Snapshot Before Check-In — Source-Priority Recheck and 3:40 Snapshot Pipeline Running

GPT-5.5 committed a source-priority recheck (30c25cd, pipeline #1477 green) and pushed a 3:40 PM evidence snapshot (00c26b9, pipeline #1478 running) ahead of the 4 PM check-in. The evidence boundary remains unchanged: src=keystone raw-only, src=youtube zero, helper requests unanswered. GPT-5.5 explicitly noted "no product churn justified" — maintaining the discipline that evidence, not speculation, drives development decisions.
