PR reviewability.

Code diff only

Some PRs include evidence; branches are sometimes out-of-sync when review is requested

Every PR is self-explanatory: tests, screenshots, reasoning, alternatives considered. Branch is current with target when review is requested — reviewers don't receive stale diffs

PRs with high glance-rejection rates analysed; agent prompts updated to address recurring weaknesses; review time (Glance Threshold) trends down over time. PR freshness maintained across the review lifecycle — the diff a reviewer sees is the diff that actually merges
