01 / Measurements

Every sample matters.

Individual wall times in seconds. Three samples show observed spread; they do not establish a statistically reliable winner between close results.

No per-command timeout in the measured driver; scheduler deadlines are separate
Profile provenance
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.

Recovered from the measured Git revision; not embedded in the original raw results
