Publish the existing benchstat comparison as a single, marker-tagged PR comment so reviewers see the numbers without leaving the PR. The comment is created on first run and updated in place on subsequent pushes to the same PR, keeping one stable comment per PR. The comment is gated by pull_request only and posted with continue-on-error: true, mirroring the coverage-delta workflow in tlabs-xyz/threshold-dapp. The diff in the job log and the go-bench artifact remain authoritative if the comment cannot be posted.

Description
Automate the client benchmark regression check and make its baseline selection match the event that triggered the workflow. The benchmark job now runs for pull requests, pushes, scheduled runs, and manual dispatches instead of relying on a manually seeded
mainartifact.This also updates the BLS threshold-recovery benchmark to the production random-beacon workload: 33 shares from a 64-member group. It reports measured p50, p95, and p99 latency, with at least 100 observations so p99 is not derived from an undersized sample.
No production BLS implementation changes are included.
Changes
go-benchartifact is found.BenchmarkThresholdVerifywith the production 33-of-64 beacon configuration.Measured BLS baseline
Pinned measurement protocol: Go 1.24.1, prebuilt test binary,
GOMAXPROCS=1, CPU 0,-test.cpu=1, ten 2-second repetitions,schedutilgovernor.ns/opThe throughput figure is derived from reciprocal latency. It is not a loaded-service throughput measurement.
Baseline behavior
A pull request artifact does not seed its target branch. If the target branch has no successful push artifact yet, the comparison is skipped with a notice. The first successful push run on that branch establishes the baseline. First-seen metric units are also reported and start gating after a qualifying baseline exists.
