Describe the material you need. Analysis is deterministic (governed dictionary and rules, no AI, no internet): it proposes class, template and values with their source; nothing is created in the material master at this step.

Required template attributes are marked *. Every value keeps its provenance: RULE (extracted from the text or derived, with rule code) or ENGINEER_INPUT for manual edits.

Exact manufacturer + part number is an identity signal in the duplicate check.
