calibration
Let an agent explain calibration and its principles, describe procedures and traceability for instruments and models, support planning calibration and interpreting certificates, and support learning in metrology.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain calibration and its principles, describe procedures and traceability for instruments and models, support planning calibration and interpreting certificates, and support learning in metrology.
The planned process of comparing the output of a measuring instrument, sensor or model against a reference standard of known accuracy and adjusting or documenting its response so that measurements are traceable and reliable, including calibration of laboratory instruments, seismometers, cameras and displays through colour and radiometric calibration, flat-field correction in imaging, and calibration of computational models against observations; calibration is fundamental to metrology, quality systems and scientific validity.
What it is for: Comparing instruments or models to references.
It can be explain principles; describe procedures and traceability; support planning and certificates; support learning.

What it looks like
Not physical as a process; involves standards, instruments and records.
How it is recognised
Comparison to a reference standard
Adjustment or documentation of response
Verification checks conformity; adjustment alone is not calibration
