Asking Ceres
Ceres answers with the figure, its status, the records behind it and the gap.
When a live model is configured, Ceres must call a tool, every number in the answer must appear in the tool output, and the status comes from the tool result. If any of that fails, Mati answers from its deterministic engine instead.
Ceres does not guess. If the data is not there, it says Unmeasured.
