Measurement conventions

Measurement conventions define the meaning of coordinates exported by domain adapters. They complement the environment-profile schema, which defines how a coordinate is transported, validated, and compared.

Each convention records:

• the domain and measurement scope
• the starting subject and required evidence
• the estimator and unit for each coordinate
• validity, missingness, and infrastructure rules
• its stability level and revision

New conventions begin at development. A convention becomes stable only after it has multiple real producers, a demonstrated consumer, conformance tests, and a documented migration policy. Adding a new convention does not require a Rust CLI change. Changing the meaning of an existing coordinate requires a new revision, and profiles with different revisions are incompatible by default.

The domain study remains the source of scientific truth. A profile exposes a small, typed view of its measurements and references the native records by URI and digest.

Current conventions:

• Formal-verification grouped probe v1
• Finance-operations policy qualification v1
• Legal policy-response measurement v1
• Robotics episode probe v1
• Robotics CUPID candidate measurement v1
• Materials residual audit v1
• Materials MLIP candidate measurement v1
• Materials MLIP candidate measurement v2
• Molecular reaction-bank measurement v1
