- 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
