Minor Changes

• BREAKING CHANGE: RoutePattern no longer exposes its parsed internals. Construct patterns with RoutePattern.parse(), and use pattern.source, pattern.toString(), or pattern.toJSON() instead of reading parsed internals such as pattern.pathname.tokens, pattern.hostname, or pattern.search.

  Added getRoutePatternCaptures(pattern) for supported capture introspection. It returns readonly { part, type, name, optional } entries in source order so consumers can inspect the variables (:name) and wildcards (*name) declared in a pattern without relying on internal parser tokens.

  Exported RoutePatternCapture and RoutePatternJSON from @remix-run/route-pattern, CreateHrefErrorDetails from @remix-run/route-pattern/href, and MatchParamMeta from @remix-run/route-pattern/match.

Patch Changes

• Fixed several route pattern matching and href generation edge cases: ignoreCase now applies consistently to pathname matching, key-only search constraints keep generated hrefs matchable, pathname params use encodeURIComponent segment encoding, hostname params reject URL-structural and control characters, optional joins no longer generate duplicate slashes, missing-param errors report every missing required param, optional variant duplicates are collapsed, port-only origins are rejected, and protocol/port constraints participate in specificity.

• Fixed route pattern helper types so literal pattern types follow the same grammar as runtime parsing. Invalid literal patterns now evaluate to never in CreateHrefArgs, MatchParams, and JoinPatterns, while broad string patterns remain usable.
