Reading guide: start with applicability and required evidence, then read expectations together with their limitations. Understand C, NC, NT and NA outcomes · Prepare a dossier

Expectations and evidence

Required inputs (protocol identifiers)
sitemap, change-history
When it applies
Sitemaps containing lastmod.
How to check
Compare lastmod with editorial history or a significant content deployment.
Expectation
Each tested date maps to a traceable significant change; file generation alone is insufficient.
Evidence to retain
ISO 8601 timestamp tied to an actual change, not file generation.
Non-applicability
No lastmod declared; its absence is not itself a defect.
Limitations
The engine may ignore a lastmod it considers unreliable.
Outcome clarification
C requires all expectations across the declared scope. NC requires evidenced contradiction; otherwise NT. NA requires evidence of non-applicability.
Reference scope
Technical reference; the TSEP acceptance rule remains an editorial proposal.
