The calibration loop

3 roles held together by 3 governed relationships, across 3 kinds. Found 1 time in the model.

Open on the board →

A loop: its roads form one cycle, so what is sent along them comes back to where it started, and the model holds at least one set standing all the way round.

Its roles— 3

A role is a place in the shape and the kind of thing that may fill it. The count is how many fill it across every instance.

• metrica Metrics1 metric fills it
• designa Evidence Designs1 evidence design fills it
• parametera Parameters1 parameter fills it

How they are held together— 3

Each is a relationship the registry declares, asserted in the direction the model stores it.

• metricread by → design
  read back: design establishes
• designcalibrates → parameter
  read back: parameter calibrated by
• parameterparameter of → metric
  read back: metric parameterized by
