Truth boundary: credential states are definitions, not achievement claims. External action is never inferred from a template, locator, or prepared artifact.

Assessment designs

Bounded community transaction or externally reviewed local equivalent authentic_delivery

A single small, non-duplicative, reviewable contribution, submitted only with separate human authorization; if external action is unsafe or unavailable, use independent local review and a weaker label.

Instructions: Record the actual state: prepared, submitted, acknowledged, accepted, merged, published, rejected, withdrawn, unknown, or externally_reviewed_local. Acceptance is not required and must not be inferred.

O017-ASMT-BOUNDED-COMMUNITY-TRANSACTION · 33 outcomes · 5 evidence specifications

  1. O017-CRIT-BOUNDED-COMMUNITY-TRANSACTION-01 — One target, one contribution, the version, locators, duplicate search, rights, and what will remain untouched are narrowly specified.

  3. O017-CRIT-BOUNDED-COMMUNITY-TRANSACTION-03 — Each external action has separate human authorization for a specific target; without authorization, the package stops locally.
  4. O017-CRIT-BOUNDED-COMMUNITY-TRANSACTION-04 — Each external transition has event evidence; prepared is not called submitted, and submitted is not called accepted, merged, or published.
  5. O017-CRIT-BOUNDED-COMMUNITY-TRANSACTION-05 — If external action is unsafe or unavailable, an independent checker assesses the actual package and the result is labeled externally_reviewed_local, with no claim of community participation.
