How to use CPIN: serve a human-approved answer verbatim

CPIN pins a golden answer that's served word-for-word for matching questions, with an audit trail of who approved it.

For pricing, legal, or brand lines, 'close enough' is wrong. CPIN serves an exact approved answer and records who pinned it; CPINGET checks for a match.

> CPIN "what is your refund policy?" "Full refunds within 30 days, no questions asked." BY legal-team
OK

> CPINGET "can I get a refund?"
1) "Full refunds within 30 days, no questions asked."
2) "pinned by: legal-team"

Pinned questions never reach the model, so there's no chance of an improvised answer on the sentences that matter most. CPINLIST audits them; CUNPIN removes one.
