ProofPowers is a deterministic safety gate for AI agents: no send without a rule check and one yes.

I wanted AI to work for me, but I ended up watching the spinner, approving every step. ProofPowers checks each action against 8 fixed rules (R-01 to R-08) and returns PASS, BLOCK or HELD. Internal work runs on its own, unsafe steps are blocked, and anything that leaves waits for one human yes on the exact payload (hash-matched, so a tampered message can't slip through).

Built for solo operators whose agents can send outreach, publish or spend money. Today the external action wired up is outreach_send; pay, post and delete are planned.

Proof: npm test 52/52, npm run cases 13/13 (hard gate PASS), 60-second mock demo with no API key, no network, $0. In the demo, the same agent without the gate leaks a fake customer record; with ProofPowers, 0 records are sent.
