Blocks: artifact export, external release

Abstentions and limits

Abstention conditions

  • Pdp Fraction Of NPV is missing or unverified: CRUX abstains until the required evidence is supplied and validated.
  • Pdp PV-10 USD is missing or unverified: CRUX abstains until the required evidence is supplied and validated.
  • Qi Boed is missing or unverified: CRUX abstains until the required evidence is supplied and validated.
  • Pdp Reserves Mmboe is missing or unverified: CRUX abstains until the required evidence is supplied and validated.

Known limitations

  • Preview capability: useful but incomplete eval or SME coverage; human review required.
  • Use a narrower skill when the ask is a specific workstream with stronger domain gates; do not use as a shortcut around missing sources, approval gates, or specialist abstentions.
