--- type: concept okf_version: 0.2 title: "Multi-verified concept" generated: { by: process:fixture-author, at: 2026-09-02T00:00:00Z } verified: - { by: human:fixture-reviewer, at: 2026-09-02T09:00:00Z } - { by: process:fixture-nightly, at: 2026-09-02T10:00:00Z } --- Two independent verification events: a human sign-off FIRST, a nightly process SECOND. The order is the whole point of this file. A reader that keeps the last entry it sees reports machine-confirmed for a concept a human actually signed off, so the tier flips downward without anything failing — the defect has no error channel of its own.
