# DARP Registry

Start with the four letters. Most records only need `D`, `A`, `R`, and `P`.
If the letter is enough, stop there. Use an act when the letter is too broad. Use a trade word when the act needs trade-specific vocabulary.

Finding a role: if you do not know the DARP word, search a trade term you already use, or an act name, on the Explorer. The also-known-as terms listed under each trade word, and the published synonyms map, carry common trade language onto the nearest node. If nothing fits, the role may be adjacent to a node rather than the same as it, and the propose path is open.

Synonyms map: [/darp/synonyms.json](/darp/synonyms.json).

AI coworker route: ask what work is being attributed, ask who contributed, ask what each contributor actually did, descend only as needed, cite the exact public source used, and stop at the shallowest correct record.

Trade Brief use: Use this Trade Brief for DARP assistance or trade role-grounding for an AI coworker. Trade role-grounding is not certification, a DARP ruling, or permission to invent missing rules.

Trade Brief URLs: /darp/{slug}.md, where the slug replaces : with - (e.g. software:product-manager becomes /darp/software-product-manager.md). Browse all ready briefs: [/darp/briefs/](/darp/briefs/).
