Decision Assurance Infrastructure
Summit Cognitive
§ Platform

The lifecycle of a machine-generated decision, covered end to end

Four assurance surfaces, one evidence model. Intelligence informs the decision, governance constrains it, verification proves the system that made it, and the receipt outlives all of them.

§ 01

The stack

Each surface stands alone; together they share one deterministic evidence substrate — the same canonical IDs, the same trust states, the same signatures.

§ 02

One evidence model underneath

The reason the surfaces compose: every artifact — a graph node, an agent action, a verification run, a media file — resolves to the same deterministic evidence identity and lands in the same signed chain.

  • Deterministic evidence IDs. Identical content yields identical identifiers, everywhere — canonical JSON, content-addressed.
  • Trust states, not vibes. Material moves through explicit states — raw, proposed, validated, approved — and policy decides what each state is allowed to influence.
  • Policy as code. Deny-by-default rules evaluated at decision time, recorded in the receipt, exportable for your auditors.
  • Signatures that outlive sessions. Ed25519-signed receipts, independently verifiable — no Summit account required.
