using sample code for OAUTH2 in its "delegation" use case shows a consent.aspx page using the ACS management service to deposit a delegation record. The latter identifies a one-time authorization code that can then be used (by such as a windows phone app) to get a first access token - and a (first) refresh token for minting new access tokens. Of course access tokens expire, by default at 600s because of the lifetime setting set in the RP entity associated with the delegation entity instance (settable, also, using ACS console).
what happens if I delete the delegation record (after the first access token has been minted)?
What are the INTENDED semantics, in terms of the OAUTH2 protocol?
