Motivation

The "Benchmark React", "Benchmark", and "Benchmark Spread" PR comments compare one GitHub runner against the last stored master run on a different runner. Runner speed alone can shift a whole run, so these comments read like regressions when nothing changed. For example, #4097 measured 1.00 in a same-machine A/B. The existing variance thresholds assume same-machine runs.

Solution

Docs only. No workflow changes and no changeset, since nothing under packages/* changes.

• examples/benchmark-react/README.md: a new "Reading the CI comment" section, the only full write-up. It has a table that maps what the comment shows to what to do (treat it as runner noise, or run an A/B), the local A/B commands for React and Node, and a note that the path filter can leave the stored baseline stale.
• examples/benchmark/README.md and .cursor/rules/benchmarking.mdc: one-line pointers to that section. .claude/rules/benchmarking.md is regenerated with yarn build:agent-rules.
