Refresh only actual on-screen review cards and the selected visible review panel, with a single metadata owner per execution host. Open reviews refresh every 60 seconds when selected and 120 seconds otherwise. Settled merged reviews stop automatic refresh; pending merged checks continue, hidden rows stop, and work changes or stale re-exposure discover fresh state.
Remove the polling setting. Preserve provider/SSH/runtime ownership, mixed-version cache behavior, failure backoff, bounded foreground admission, request coalescing, and mutation invalidation. Cover older persisted caches and unknown HEADs.
Validated with 1,628 focused tests, typechecking, lint/code-quality gates, hidden Electron viewport checks, and parallel Codex/Claude Opus 5.5 adversarial reviews. Measurements and policy details are in PR #25788.
