// Static-grep tripwire for the v1.44 internalHandler refactor.
//
// /internal/grant and /internal/revoke were copies of the same dance:
// bearer-auth → x-browse-gen check → req.json().then(...).catch(...).
// internalHandler<T>(req, fn) collapses that into a single helper call.
// This test fails CI if the helper goes away or the existing routes
// regress to inline auth + JSON parse boilerplate. Wiring tests
// (token grant/revoke behavior) already live in
// browse/test/terminal-agent-integration.test.ts.
