Descriptive label reconstructed from the measured driver; not an original profile identifier

Historical protocol recovered from the measured driver. These fields were not embedded in the original result. The raw JSON remains unchanged.

03 / The implementation

Read what ran.

The implementation and supporting files at the measured revision. Highlighting is added for readability; the source text is unchanged.
