What Ota governs

Ota governs declared repository execution: readiness, admission, selected work, and bounded evidence for humans, CI, and agents.

  • Explain the scope of Ota governance in one sentence

Contract, execution, admission, and evidence

The four pillars of Ota: a declared contract, deterministic execution, admission gates, and receipts that prove what actually ran.

  • Name the four pillars and state what each covers
  • Explain why evidence must be separate from execution

Declared, observed, and proved

  • Define all three truth levels with an example
  • Explain why Ota refuses to treat declared as proved

When Ota cannot verify a claim, it must say so explicitly. not_proved is a first-class result, not a failure.

  • Explain what not_proved means in a receipt
  • Describe when Ota emits a not_proved boundary
