The task

pint lacks UCUM support, the unit-code system HL7, FHIR and LOINC require. Implement a UCUM engine as a new pint.ucum subpackage. The Unified Code for Units of Measure, version 2.2 ([source link]) is the sole authority: its grammar (Exhibit 1 as amended by the §§1–12 prose), its semantics (§§16–26), and its tables.

Results by model and effort

This exact task version only. Every rate is passes / valid runs with a Wilson 95% interval; n≤2 remains counts only. Macro aggregation does not apply within a single task. Baselines are summarized in the quality gates, not ranked. A passed no-op resistance check means that doing nothing did not solve the task.

5 recorded trials, including controls. Diagnostic labels do not replace verifier reward. Labels and quality checks are source declarations, not independently attested here. Internal evidence remains private; a missing public URL is shown explicitly. Records with invalid or absent rewards are not scored.
