The unexplained-rejection gate from #114644 ended the turn with "another request on the same
server was probably holding its capacity ... wait and /retry" whenever a server said "context
exceeded" without a count while the local estimate sat under half the known window. That cause
only exists on single-slot local servers. On a hosted route (Anthropic, Nous, OpenRouter, any
public endpoint) the same rejection means the route's real window is smaller than the one Hermes
assumes, so /retry failed identically every turn and the conversation was never compressed:
Discord bots on claude-opus-5-5 were stuck repeating the message.
The gate now also requires is_local_endpoint(base_url) (loopback, LAN, Tailscale, container
DNS). Hosted endpoints return to the compress-and-retry path they had before #114644. The FAQ
entry says which endpoints get the message.
