Receipts
Proof, not promises
What it is
A dashboard of receipts for the claims on this site. Engine CI comes live from the GitHub Actions API; frame rate and page weight are measured in your own browser through FrameTiming and the Performance API; the Lighthouse baseline is shown with the method used to record it. Numbers appear only where they can be checked.

Under the hood
- Engine receipts come from the GitHub Actions API, so a red build shows up here as a red row after the next push.
- Frame rate is sampled in your browser with Flutter's FrameTiming callbacks while the shell animates; page weight is summed from the Performance API with real transfer sizes.
- The recorded Lighthouse baseline is shown with its method so it can be reproduced, not just trusted.
- Claims without receipts were left out of this app — the limitations say exactly what each number does and does not cover.
Honest notes
- GitHub allows 60 anonymous API calls per hour per IP; when that runs out the panel says so instead of guessing.
- Frame rate depends on your device, browser and how busy the machine is — it measures your session, not a benchmark.
- The Lighthouse numbers are a snapshot of one throttled mobile run and will drift as the site changes.
