Evidence records 5/5. Automated screenshots 2/5.
This is not a success-only performance chart. v0.1 publishes successful evidence records alongside failed screenshots so readers can see what the product can—and cannot—guarantee.

Case results
Failure states are results, too.
Each case requires a retrievable record, exact quote, locator, and HTTP-200 public evidence page. Screenshot capture is scored independently; source blocking and browser errors are not relabeled as success.

Inspect public evidence ↗Method and limits
We manually verified passages from five public primary sources, submitted those pre-verified passages to the production evidence API, and checked public pages from outside the production service sandbox. The test therefore measures faithful evidence preservation and publication—not whether a model independently finds the right passage.
Five cases cannot estimate a general success rate, and third-party defenses can change. The NASA PDF browser_error, W3C cloudflare_challenge, and SEC access_denied outcomes are retained verbatim.
