| Name | Type | Description |
|---|---|---|
value* | object | Raw value read from checkpoint state. |
Narrow a persisted model-spec channel to a usable value.
Shared by _rubric_model_spec and _model_spec. INHERIT_RUBRIC_MODEL
passes through unchanged; callers compare the result against it themselves.
Every reader of these channels must go through this, so the TUI display and
the grader cannot disagree about a malformed checkpoint value.
