pub async fn drill_down(
report: Report,
bees: &[String],
timeout: Duration,
concurrency: usize,
) -> Result<Report>Expand description
Walk the manifest at report.reference, probe each leaf chunk via
GET /chunks/{addr} from every vantage, and attach the result to
the report. When the per-vantage overlay is known (already fetched
in check_multi_vantage), each ChunkVantage also carries the
proximity between that vantage and the chunk.
