Method: Send a GET request, follow redirects and record the final status code.

Criterion: Each GET reaches a final 200 response for the expected resource; retain timestamp and redirect chain.

Limits: A test from one IP does not prove the response received by Googlebot.

TS01 · TSEP 0.3.0-draft.8 · Required evidence: Intent, complete GET trace and retained body; reasoned findings for A01–A02.

Assessment applies the engine to supplied captures and reviews. Automated observations and your declarations are not sufficient to constitute this evidence. Your selected controls are carried into this step.

How this example is verifiedSame engine, same expectations before and after

Responses, pages and dates are fictional. The seven reports were calculated by the TSEP engine, then replayed offline from their evidence. Expectations stay identical before and after each correction.

The plan owner’s decision and the access review are fictional evidence marked as synthetic exercises. They go through the same adapters as the real TS02 and TS04 workflows. TS07 still needs two pieces of evidence: unobstructed access and browser rendering. The other 40 controls are outside this example. No Googlebot visit, indexing or JavaScript execution is claimed.
