Both the wire path and the picker only consulted the catalog's
`mandatory` flag, so a route the Portal lists as accepting no reasoning
parameter at all still got sent a disable, and still offered a Thinking
toggle in the model picker.
For a route it serves, the aggregator's own catalog outranks the
models.dev inference: `supports_reasoning: false` now suppresses the
disable on the wire and drops reasoning controls from the picker
entirely, so there is no disable left to describe.
The picker offered an off switch for every reasoning model, including routes
whose upstream answers a disable with HTTP 400 — so "thinking off" was a
control that could not work. Carry the catalog's mandatory verdict through
model.options as can_disable_reasoning and hide the toggle when it is false.
Effort levels are left alone. The catalog's supported_efforts under-reports
what the Portal serves (z-ai/glm-5.3 publishes max, high, low yet honors
minimal at its lowest thinking), so filtering the scale by it would hide
levels that work.
