Hotspot-first, multi-pass code review for pull requests, branches, pasted diffs, and work-in- progress changes. Models behavior changes, selects risky hotspots, acquires minimal local context, generates candidate findings and questions, runs a skeptic pass and dedup, then surfaces at most 5 high-signal outputs.…
