+"""Renew the stored SSO identity assertion so an ID-JAG agent outlives one id_token.
+
+The ``oauth2_id_jag`` arm asserts the id_token captured at the user's last interactive sign-in, so
+without renewal an agent holding a brokered LiteLLM key can act for that user only until that token's
+``exp``, typically an hour, and the sole recovery is another interactive login. The assertion already
+carries the IdP refresh token beside it; this module is what redeems it.
+
+``RefreshingSSOAssertionStore`` wraps any ``SSOAssertionStore`` and satisfies the same protocol, so
+the egress arm is unchanged: it still reads one assertion and still judges expiry itself. Renewal is
+lazy (only a read that finds a near-expiry assertion triggers one, so IdP traffic tracks actual use,
+not the size of the user table) and single-flighted per user through the same ``RefreshCoordinator``
+the ``authorization_code`` arm uses, because an IdP that rotates refresh tokens treats two concurrent
+redemptions of one token as replay and can revoke the whole grant chain.
+
+The refresh is redeemed against the generic-OIDC client the login itself used
+(``GENERIC_TOKEN_ENDPOINT`` / ``GENERIC_CLIENT_ID`` / ``GENERIC_CLIENT_SECRET``, which the proxy
+reconciles from the stored SSO row into the process environment at startup), authenticated the way
+that login authenticated: the non-PKCE path always sends HTTP Basic, while the PKCE path sends the
+credentials in the body when ``GENERIC_INCLUDE_CLIENT_ID`` is set, and an IdP application may accept
+only one of the two. An assertion can only exist if that client minted it, so no other client could
+redeem its refresh token, and no other method is known to be accepted. A deployment whose
+``GENERIC_SCOPE`` omits ``offline_access`` captures no refresh token at all, which is why that miss
+logs the scope by name rather than failing silently.
+
+Failures are values internally (``Result[_, RefreshFailure]``). At the store boundary they collapse
+onto the protocol's existing two-outcome contract: a refusal returns the expired assertion unchanged
+so the reader's own guard challenges the user to sign in again, while a transient IdP failure raises
+``AssertionStoreUnavailable`` so the reader answers 503 instead of blaming the user for an outage.
+
+One ambiguity remains under Redis-coordinated renewal across replicas. A cross-replica loser that
+finds the row still expiring after the holder finished cannot tell a refused refresh from a renewal
+that could not be recorded. Redeeming itself could consume a refresh token the holder may already
+have rotated, so it answers retryable 503 rather than guessing a sign-in challenge. The next
+uncontended read settles the outcome itself: a refusal challenges, and a successful refresh persists.
+If the holder rotated the token but its write failed, that rotation is lost and the next uncontended
+read's refusal challenges, which is the only honest answer because the rotated token was never
+recorded. On the refusal path, the loser pays for one retry before that challenge.
