+// --- Overleaf patch: request-input lockdown compatibility ---
+// This strategy reads req.query directly to parse the OAuth2 protocol
+// fields (error/error_description/error_uri, code, state) it's built
+// around, which is otherwise indistinguishable from unvalidated application
+// code reading raw request input under Overleaf's request-input lockdown
+// (see libraries/validation-tools and the patched express in
+// .yarn/patches/express-npm-*.patch). The lockdown captures the original
+// parsed values in symbol-keyed fields, registered in the global symbol
+// registry (the same ones @overleaf/validation-tools' lockdown.js reads),
+// and only turns the *public* req.query property into a throwing accessor
+// -- reading through this raw field instead sidesteps that, and is
+// identical to plain req.query when the lockdown isn't installed (i.e. for
+// every consumer of this package outside this monorepo).
