Hermes' internal effort vocabulary extends the wire set with ultra
(documented by /reasoning as none..xhigh|max|ultra). OpenAI-compatible
wires — OpenRouter chief among them — accept exactly
max|xhigh|high|medium|low|minimal|none and reject the extension with
HTTP 400, so an ultra configured while the default model was Anthropic
worked (the Anthropic adapter maps its own levels) but leaked
untranslated the moment a per-job override pinned a non-Anthropic
model, failing every call for that job.
The wire-compat chokepoint for this transport previously mapped
ultra to max only for gpt-5.6; generalize the cap to every model.
