Field	Type	Default	Description
`baseURL`	string	— (required)	Upstream base; every chat request posts to `${baseURL}/chat/completions`
`apiKeyEnv`	string	— (required)	Environment-variable name resolved per request
`agentType`	string	`agent`	Reported as `session.agent_type`
`priority`	`{level, reason}` or `null`	`{level: 3, reason: "user_waiting"}`	Soft priority; `null` omits the field
`cacheControl`	array or `null`	`[{type: "pin", range: {end: 1}}]`	Cache control entries; `null` omits
`thinking`	`"enabled"` / `"disabled"`	enabled	`disabled` limits every conversation request to `off`
`reasoningEffort`	`"off"/"low"/"high"/"max"`	`high`	Default reasoning effort when a request carries none
`models`	`{id, name, contextWindow, maxTokens}[]`	DeepSeek-V4 family catalog	Advisory model catalog for `resolveModel`; provide real limits when pointing at your own gateway (they feed compaction decisions)
`defaultContextWindow`	positive integer	`1000000`	Context window assumed for models absent from the catalog
`defaultMaxTokens`	positive integer	`256000`	Per-request output cap materialized when callers omit one
`statusSink`	string	unset (channel off)	Local JSONL path for out-of-band status events
`subagentToolNames`	string[]	`["subagent"]`	Tool names treated as subagent delegation for `derivation.join` and status naming

Invalid config aborts composition at load time with a field path — request-time hint construction has no failure path.
