 # IMS / NASA-Bearing — fault classification from the envelope spectrum (reasoning track)
 
-Second signal dataset in the AI4Manufacturing FORGE corpus (Category **C**, task **T-C1**), from three **run-to-failure** experiments. Each record is the **envelope spectrum** of a 1 s vibration window with fault frequencies marked — the representation for faithful **compute-then-check** CoT. `reasoning` is empty; the **`IMS-annotated`** sibling fills it.
