🔑 Key Trends & Next Actions

1. Perf regression cluster (perf: fix ParseWorkflow regression (+29% → -51%) via targeted caching #44994/perf: fix CompileMemoryUsage regression by optimizing normalizeBlankLines and findRunValue #44995/perf: cache builtin alias map and DFS cycle-check to fix CompileMCPWorkflow regression #44996): Three related caching fixes targeting compile/parse regressions — review together to avoid conflicts.
2. High-priority bug (fix: resolve COPILOT_MODEL aliases at runtime before spawning Copilot CLI #44975): Runtime model alias resolution — large change but CI green, needs prompt review.
3. Empty draft (Refactor expired entity close/comment flow for issues, PRs, and discussions #45044): Zero-diff PR is likely a placeholder; should be closed or developed further.
4. Custom engine PR (Add declarative custom-engine frontmatter and migrate Crush/OpenCode to shared behavior definitions #44465): Oldest and largest PR; needs dedicated focused review session.
