b9246 was 52 days / 721 builds old. Validated on Tess dual (full quality A/B, 2026-07-11): think-OFF total tie 115=115 (greedy-leg engine isolation — totals neutral, though 4 scenarios flipped each way), think-ON 122 vs the 118x3 pin — the lift is thinking-path-specific; 3 previously-100%-reproducible failures now pass (CLI-31 safety refusal, CLI-20 archive precision, RM-04 math). Boots clean, draft-mtp works. Also unifies the pin landscape: Deckard's b9570 and the ROLLING tags on gemma-12b/vibethinker (a #187-policy violation — rolling crash-looped at b9282) all move to the same validated build. Engine-profile spec now matches the composes. Non-Tess slugs: boot re-validation is spot-checked (smoke to follow on PR); bench numbers stay dated to their measured pin; baselines rows go stale by design (the staleness badge is the feature).
