/**
 * `src/services/observability/results-baseline-rows.ts`
 *
 * WHY THIS MODULE EXISTS. The published rows and the old-vs-new metric
 * comparison are the two parts of the results baseline that decide what a
 * reader is shown, and both are big enough to push the computation module
 * over the repository's 300 raw-line file-size cap.
 *
 * THE RULE THE ROWS OBEY. Every published row is a RATE or a PEAK. A raw
 * count that grows with the number of slices ever recorded is a population
 * descriptor, not a baseline row — those live in their own block of the
 * artifact, and a reader must never mistake one for the other.
 *
 * THE RULE THE COMPARISON OBEY. Version 1 of the repair-cycle metric counted
 * qa-role slice-transition events — QA's own internal state transitions,
 * doubled by the duplicate emission — and was never a repair-cycle count.
 * Version 2 counts repair cycles. The two are recorded side by side so the
 * historical numbers are read as a DIFFERENT MEASUREMENT, not as a
 * regression.
