Cuts the wait from push to green by measuring a pipeline's critical path from run timestamps, then splitting, sharding, trimming setup and sharing test module state, with a before/after ledger. Use when asked to "speed up CI", "CI is slow", "why does a PR take 15 minutes", "CI is the bottleneck", or when agents merge faster than checks finish.
