isValidUrlGlobPattern accepts characters like ( ) [ ] { } | . + ^ $ in PATH rule values, but isPathAllowed converted wildcard segments to regex without escaping them. A rule value such as /(api* produced an invalid regex and threw on every request to the resource, surfacing as a 500 from verifySession. Literal characters like . and + also changed matching semantics. isPathAllowed is extracted to server/lib/pathMatch.ts as a pure module, metacharacters are escaped before wildcard substitution, compiled segment regexes are cached, and the test suite now imports the real implementation instead of a stale copy, with added coverage for special characters.
