How it works

Check increasing bounds and nondecreasing integer counts. Require a final +Inf bucket equal to _count; subtract adjacent counts for each bucket’s local count.

Counts 10,20,30 yield local bucket counts 10,10,10; +Inf equals the supplied count 30.

Limits

One classic histogram snapshot as a two-column table. This does not parse a full metrics file, native histograms, rates or quantiles. Counts must be whole nonnegative numbers.
