If the backing AsyncKeyValue store errors or the task is cancelled after _storage_oauth_token.put() succeeds but before this second put() completes, the cached token and token_expiry record diverge. OAuth._initialize() now prefers the separate expiry over current_tokens.expires_in, so after a restart a freshly refreshed token can be treated as already expired (or an old token as still valid). Because set_tokens() mutates two independent keys with no rollback, a transient store failure now corrupts persisted auth state.

When OAuth tokens are reloaded from cache,
_initialize()recomputes the expiry astime.time() + expires_in. Butexpires_inis the original relative value from token issuance — a token issued withexpires_in=300that's reloaded an hour later appears valid for another 5 minutes, preventing the client from triggering a refresh.The fix stores an absolute
expires_attimestamp alongside the token at cache write time. On reload,_initialize()uses that directly instead of reinterpreting the stale relative value. Falls back to the old behavior for caches written before this fix.Closes #2862
