Snapshot of the in-flight state that already existed, identically, in both this worktree and the main checkout before this session began: the initial HTTP Client platform implementation (previously untracked), the redis-lab removal, and the JPA / object-storage / notification integration work. Kept separate from this session's HTTP Client review response, which lands in the following commit, so the two bodies of work stay reviewable apart.

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.
