benchtrend

Overview ¶

Command benchtrend keeps the github-action-benchmark microbenchmark history compact without sacrificing commit granularity.

The perf gate deliberately runs `go test -count=10`. Feeding that raw output to github-action-benchmark stores all ten samples for every metric, even though the dashboard needs one representative point per commit. The convert command emits the median ns/op, B/op, and allocs/op values in the action's custom JSON format. The compact command applies the same median rule to the existing benchmark-action data.js history and removes the action's redundant composite Go points.

Both modes are standard-library-only and fail closed on malformed input.
