Primust is the independent clearinghouse for AI-agent actions. It checks each action against the agent's authority and a real system-of-record receipt where one exists, then settles the result into signed evidence the next person, workflow, or agent can build on.
The record of what an agent did shouldn't be written by the agent that did it. Primust reconciles what it was allowed to do, what it was asked, what it said it did, and what the destination record shows, then labels exactly how independently each answer was confirmed.
Primust checks what an agent said it did against what actually changed — the commit, the database row, the system it touched — and packages it into one record another party can verify offline. Not a dashboard. Not a replacement for your controls. Content stays with you; only commitments, pointers, and metadata ever travel.
The verifier and Controls Harness are Apache-2.0. Anyone can check an Evidence Pack without paying us a cent — proof infrastructure has to be open to be trusted.
