/**
 * log10x_backfill_metric: DEPRECATED, kept dark. Builds a TSDB metric from the
 * offloaded cohort in the customer's S3 overflow bucket. Not advertised: the live
 * routeState metric surface answers overflow-volume questions as a TSDB query.
 * Retained only for the narrow custom-dimension case.
 *
 * Reads the offloaded cohort for a pattern from the overflow bucket over a window,
 * aggregates it into a bucketed time series, and emits the result to the destination
 * TSDB with original timestamps preserved.
 *
 * Optionally wires forward emission via the live Reporter so the metric keeps
 * populating from current events. Coverage spans the window the offloaded bytes
 * were retained in S3, so the series reaches back as far as the bucket holds the
 * pattern, not further.
 *
 * Tier prerequisites: Retriever component required; Reporter required
 * only when emit_forward=true.
