Add a direct rejection case for cl_I7d4PD111III.
No checked-in test calls the real verifyHandshakeToken with this legacy category. The existing rejection cases would not catch a regression that accepts only cl_I7d4PD111III.

Add a legacy-category regression case to authenticateRequest().
The existing test covers JWT_CATEGORY_JWT_TEMPLATE, not cl_I7d4PD111III. Add a case that signs a token with the legacy category, calls authenticateRequest(), and asserts AuthErrorReason.TokenTypeMismatch. The handshake rejection test does not cover this authentication caller.

authenticateRequest()andverifyHandshakeToken()check thecatheader to make sure a token presented as a session token really is one. They have carved outcl_I7d4PD111III, a legacy category Clerk no longer issues, since that category used to be stamped on every token type.This removes the carve-out. A token carrying that category now gets a signed-out state with
token-type-mismatch, like any other non-session category. Session tokens always carry the real session category and are unaffected. Tokens with nocatheader are still accepted.#10257 edits the same line in
jwtCategories.ts, so whichever lands second needs a trivial rebase.🤖 Generated with Claude Code
