Mohar

Trust, earned.

Mohar watches what an AI agent does, checks whether the result was right, and turns that record into permission, one capability at a time. One wrong move on a gated capability and the right is gone. Every decision is sealed with a receipt.

Tilt the stamp with your pointer. Click it, or run the agent below, and it presses a receipt.

People approve almost everything, and the systems they approve break fast. Mohar asks less often, and only about actions an agent hasn't earned.

Run an agent for a week

Mohar's rules, running in your browser. Each task is checked by tests, never by the agent's opinion of itself. Receipts form a real SHA-256 chain; the browser demo has no keys, so it doesn't sign them.

    One decision, four steps

    Instant

    As long as your tests take

    Instant

    Instant, or a person

    Record
    The action goes into a local hash-chained log, signed by a key the agent never sees.
    Verify
    Tests, a diff, a replay or a person accepting the work decide the outcome. A model grading itself never counts.
    Score
    Per capability. Hard gates sit outside the score.
    Decide
    Inside earned limits it runs. Outside them it goes to the right person, with the agent's history attached.

    prev

    The hash of the receipt before this one. Change or delete any receipt and every later one stops matching.

    authority

    Who handed this agent its rights, by pseudonymous ID, so the log holds no names. Each link can only narrow what it received.

    args_sha256

    The exact action. A person's approval is bound to this hash, so a different action can't run under it.

    decision

    Why it ran: the level on this capability and the evidence behind it.

    sig

    Ed25519 over the RFC 8785 canonical bytes. mohar verify checks every one, a million in about eight seconds.

    The planned full format. The receipt log and its CLI ship today with the fields in the format reference; the full field list is in the design.

    How trust moves

    Ask first

    Every action goes to a person.

    The start, and where any gate violation or high-risk failure sends an agent.

    Supervised

    Low-risk reversible actions run; 20% are sampled for review.

    10 verified outcomes, a 95% Wilson lower bound of 0.80, and 7 days at the level below.

    Trusted

    Actions run inside the capability's gates; 5% are sampled.

    30 verified outcomes and a lower bound of 0.95. Never for high-risk irreversible capabilities.

    Five passes out of five give a lower bound of about 0.57, so a lucky streak promotes nobody. Evidence fades with a 30-day half-life. Demotion is immediate; promotion always waits. These are starting values for the benchmark to test. Read the full design
