- Normalize: https, www or bare host, double slashes and index files,
trailing slash add/remove, optional ASCII lowercasing (defaults change
nothing but scheme, slashes and index files)
- strict URLs through signpost MatchPath: a path that names a record
without being its address 301s to the record's address
- resolve runs normalisation, redirects, strict URLs, then SEO; the
location is the final address, so a visitor makes one hop
- P1 warns when a record's canonical URL redirects
- the RecordSaved listener re-describes an updated record of a content
type after commit and applies AddressChanged per changed locale, so
Journal's API, MCP and imports get the 301 too; an admin save that
already applied it changes nothing more
- POST /_seo/api/v1/notfound with the golem15.seo.notfound_token bearer
(constant-time, off when unset), URL and referer caps, a row cap with
an hourly warning, throttle bucket seo-notfound
- golem15.seo.notfound list by hits with Resolved rows, a preview with the
resolved hint, a prompted 301 and a 410 record action, a bulk 410 that
refuses a selection with a covered address
- every /_seo/api/v1 answer carries X-Robots-Tag: noindex
- golem15.seo.redirects list and form (UI-SPEC C8): chain rows marked,
status, match, origin and chain filters, the navigation item lands here
- a field-less extension on the controller refuses a loop with
redirects.loop on target, answers the chain notice and records history
- the status dropdown posts text, read through RedirectStatus
- rule set: exact sources by key, patterns by literal prefix, regex by id
(stdlib RE2, compiled once per source); ignore case, trailing slash,
query ignore/pass, a source with ? matches its query exactly
- targets: captures escaped, a relative target never leaves the site, an
absolute one keeps its host
- SaveRedirect validates, simulates the rule in place (exact, pattern and
regex probes, 10 hops) and refuses a loop; chains answer the notice
- resolve follows the chain to its final target, 410 answers gone, a
runtime cycle answers not_found and is logged once
- golem15_seo_redirects table and Redirect model
- AddressChanged: old -> new 301 in the save transaction, earlier
redirects pointed at the new address, self-loops dropped
- the SEO tab save compares descriptor URLs with the entry URLs and
answers the redirects.auto_created notice
- resolve answers redirect with the absolute target for an exact source
