Diffgram is built for humans supervising AI data. DOS (dos-kernel) is our newer open source project, built for supervising the AI agents themselves: a small, deterministic trust kernel that verifies what autonomous AI agents and coding agents actually did — from git evidence and other witnesses an agent cannot forge — instead of trusting the agent's own "done" report.

If you train or fine-tune models on agent-generated data, DOS's reward() verdict decides whether an agent trajectory may enter the training set at all, rejecting "resolved" claims that a non-forgeable witness refutes — training data quality for the agent era, the same problem Diffgram's human supervision solves for labels.
