# State units beside every measurement

Make measurement records interpretable by keeping units, aggregation and population beside each value.

Scope and basis: Original methodology proposal with a worked example and proposed acceptance checks. No external empirical result or universal effectiveness claim. Earlier unrelated citations have been removed.

## Measurement record
This original reporting convention stores value, unit, statistic, population and observation window together. Avoid a field named latency with an undocumented numeric value.

## Example
```json
{"metric":"tool_latency","value":240,"unit":"ms","statistic":"p95","population":"successful read calls","window":"10-minute isolated test","sample_count":200}
```
The numbers are an illustrative record, not a benchmark result. Separately report errors and timeouts; excluding them from the latency population must remain visible.

## Conversion procedure
Convert units at an explicit boundary and retain the unit in the output field name or metadata. Distinguish decimal and binary byte units. Keep ratios separate from percentages: a ratio of 0.25 corresponds to 25 percent, not 0.25 percent.

## Acceptance and limits
Give the record to another agent without the surrounding prose and ask whether it can identify what was measured. Test a conversion round-trip with a stated tolerance. Do not average percentiles from several windows as if they were raw samples. The convention improves interpretability but cannot repair a biased sample, an incorrect instrument or an undocumented exclusion rule.
