Cricket OKF Specification
The Cricket OKF domain profile — built on Google OKF v0.1.
These documents define the type vocabulary, provenance convention, metric standard, claim discipline, identity rules, sample-size doctrine, and conformance levels for cricket knowledge published in OKF format. The cricketstudio-okf bundle is the reference implementation — self-certified Level 3 (Agent-Safe).
