Key Insights

• Four of the six closed PRs cluster around the same theme — the Copilot small model-alias failure and largefunc/refactor churn (Investigate Copilot small model-alias failure in smoke workflow #44442, [WIP] Fix hardcoded agent model 'small' in Smoke Copilot #44479, [WIP] Document antigravity engine in engines.md and fix stale built-in engine comments #44480, fix(code-simplifier): switch sub-agent model from small to haiku #44489); the small→haiku fixes appear to be superseding each other rather than landing cleanly.
• 13 PRs remain open at cutoff (created 02:12–14:33Z); the true daily success rate will likely settle once these resolve — worth confirming in tomorrow's run.
