--- type: concept okf_version: 0.2 title: "Attested computation" generated: { by: process:fixture-author, at: 2026-09-02T00:00:00Z } verified: - { by: process:fixture-check, at: 2026-09-02T08:00:00Z } sources: - resource: https://example.invalid/fixture-cost-baseline id: fixture-cost-baseline --- One verification event, written as a single-entry block sequence — the SPEC-canonical long form of `verified: { by: ..., at: ... }`. The actor is a `process:` one, so the trust tier a consumer derives from it is machine-confirmed, never human-reviewed. `sources` is written in block form too, so a reader that only understands the flow shorthand loses the provenance of this concept entirely rather than reporting that it could not read it.
