/**
|
||
|
|
* Applies the user's explicit Small Model override (Settings → Chat → Small
|
||
|
|
* Model) to the configuration injected into the managed OpenCode process.
|
||
|
|
*
|
||
|
|
* OpenCode's own session-title and summary generation reads `small_model`
|
||
|
|
* from its config layers. Previously the OpenChamber settings override only
|
||
|
|
* fed OpenChamber's own `/api/small-model/generate` utility service, so a
|
||
|
|
* configured Small Model never reached OpenCode's title generation and
|
||
|
|
* sessions kept their fallback/untitled state. Injecting the override as
|
||
|
|
* `small_model` in the managed `OPENCODE_CONFIG_CONTENT` closes that gap for
|
||
|
|
* the managed server.
|
||
|
|
*
|
||
|
|
* Only an explicit override applies (`smallModelUseDefault === false` with a
|
||
|
|
* non-empty `smallModelOverride`). "Use default" leaves the config untouched,
|
||
|
|
* so OpenCode's own resolution chain (config `small_model`, then its family
|
||
|
|
* scan) stays authoritative — this mirrors the precedence documented in
|
||
|
|
* `packages/web/server/lib/small-model/DOCUMENTATION.md`.
|
||
|
|
*
|
||
|
|
* Malformed user config is left untouched rather than rewritten: OpenCode's
|
||
|
|
* own loader is the right place to surface it, and silently rewriting it
|
||
|
|
* would hide the error.
