+# OAuth2 fixture
+
+`OAuth2Fixture` exposes a token endpoint backed by the same deterministic fixture server as the rest
+of the suite.
+
+It counts token requests, which is what makes design §20.3's single-flight guarantee provable rather
+than assumed: a hundred genuinely concurrent callers must produce exactly one token request. It can
+also issue rotating token values, so a stale cached token is detectable, and queue a failure status
+to exercise the refresh-failure path.
+
+The token endpoint is configured as its own Named Client Profile, separate from the upstream it
+issues tokens for.
