** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by its CNA. Further investigation showed that it was not a security issue. Notes: The endpoint is public on purpose and the invitation code is the credential. This is the standalone SDK onboarding path for mobile apps that have no backend of their own: a developer generates a code via the authenticated dashboard endpoint, the user types it into the app, and it's redeemed for SDK-scoped tokens.
