Host, case and trailing-slash variants converge on one rule.

Expectations and evidence

Required inputs (protocol identifiers)

http, html, sitemap, crawl, intent

When it applies

Host, case and slash variants of resources declared equivalent.

How to check

Replay www/non-www, HTTP/HTTPS, relevant case and trailing-slash variants on sample routes; compare redirect, canonical, sitemap and links.

Expectation

Every tested variant follows the declared rule; redirects, canonicals, sitemaps and links agree without merging distinct resources.

Evidence to retain

One stable final URL per resource, no chain and consistent internal signals.

Non-applicability

No relevant variant after an explicit inventory.

Limitations

Case can be significant depending on the server and application; the rule must be tested, not assumed.

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.
