Account Linking Failure-Mode Documentation

We've expanded documentation across the Social SDK guides to cover what happens when the Discord-to-game account link is severed — whether by a Discord account ban, an explicit unmerge, or an OAuth2 token revocation. Highlights:

• Ban-Driven Unmerge documents the full lifecycle when a user's Discord account is banned: tokens are deleted immediately, a new cross-platform-restricted provisional account is created carrying the original external identity, and merge attempts return error 530017 until the ban lifts (or, for permanent bans, indefinitely).
• Out-of-Band Revocation describes the auth-side observable signals (APPLICATION_DEAUTHORIZED webhook + invalid_grant on refresh) when a user removes your app from Discord or has their account banned.
• When Refresh Fails documents the /oauth2/token response when the underlying token has been deleted, and recommends treating invalid_grant as equivalent to receiving the webhook.
