- /api/overpass: a loopback socket with forwarding headers (a local reverse
proxy) is admitted from the remote pool under a socket-keyed proxied: bucket,
never the owner's direct-loopback window; the upstream limiter uses the same
key. Regression: owner cache hits survive an exhausted proxy bucket.
- Arrival check: a reveal timeout keeps the settle angle it measured; the new
observeArrivalRotationWithRetry retries only inconclusive timeouts, so a
real violation cannot be retried into a pass. Regression: wrong settle angle
-> reveal timeout -> clean second attempt still fails.
- SECURITY.md, README, changelog and CURRENT-STATE: scope the guarantee to
admission isolation, name the forwarding headers a local proxy must send,
and state that the upstream budget stays shared.
