Reasoning models on Ollama and similar servers think by default and can
spend the whole max_tokens budget before the visible answer starts, so
the call comes back empty or times out. The Local and OpenAI-compatible
chain entries now carry an optional reasoning setting: Default sends
nothing, Off sends reasoning_effort "none", Low / Medium / High send
their own value. It is stored on the entry in aiProviderChain, so a
chain can mix a thinking model with one that does not know the field.
- Every exported resolver binds the entry's value onto the client, the
connection test included, keyed on the instance type so the operator
provider, OpenAI, Anthropic and Codex never carry it.
- PATCH /api/user/ai-provider accepts localReasoningEffort and
compatReasoningEffort and GET reports them. A provider absent from
the chain holds its value on a disabled entry; restating Default on a
chain that was never customised writes nothing.
- PUT /api/insights/provider-chain accepts reasoningEffort on local and
openai-compatible entries, refuses it on any other, and keeps the
stored value when the body leaves it out. Its schema is now shared
with the OpenAPI registry.
- A Default request body is byte-identical to the one sent before.
