Summary

Prevent warm-start tile snapshots from restoring derived aggregate health summaries over the fresh dashboard shell.

Why

A browser can keep an old system-status or runtime-health-summary snapshot from a transient monitoring failure. On the next page load, that stale aggregate could briefly show many services down until tile hydration corrected it.

Changes

  • Skip persisted/restored snapshots for system-status and runtime-health-summary.
  • Keep leaf tile warm-start behavior for telemetry, individual services, and other useful tile data.
  • Add regression coverage for snapshot-store restore and App shell restore.

Testing

  • bun --cwd apps/web test src/lib/client/dashboard-refresh.test.ts failed before the fix and passed after.
  • bun --cwd apps/web test src/App.test.tsx failed before the App restore guard and passed after.
  • bun install --frozen-lockfile
  • bun run check
  • bun run test
  • bun run build

Notes

This does not disable last-known data globally; it only avoids replaying derived aggregate summaries that can be misleading at startup.
