PART TYPE Classifier

Classifier Rules

• Classifier input is the uppercase reference designator.
• Matching MUST be longest-prefix-first (descending prefix length).
• If no prefix matches, emit OTHER.
• This reference is deterministic and intended for cross-exporter consistency.

function classifyPartType(refdes):
  token = uppercase(refdes)
  for prefix in PREFIXES_SORTED_BY_LENGTH_DESC:
    if token startsWith prefix:
      return LABEL[prefix]
  return "OTHER"
