_{Avg deltas compare against the most recent benchmark run on main at the time of this run.}

_{Metrics — TTFS: time to first step body execution · STSO: step-to-step overhead (gap between consecutive step bodies) · WO: workflow overhead (time outside step bodies, client start → last step body exit) · SL: stream latency (first chunk write → visible to the reader)}

_{Scenarios — stream: one step that streams chunks back to the client; no hooks, so the run stays in turbo mode · hook + stream: registers a hook before the same streaming step, which exits turbo mode · 1020 steps: 1020 trivial sequential steps; STSO is measured between consecutive steps in the given step ranges}

_{🟢/🔴 mark percentiles within/above target. Targets (p75/p90/p99, ms) — TTFS 200/300/600 · SL 50/60/125 · STSO (1-20) 20/30/60 · STSO (101-120) 30/45/90 · STSO (1001-1020) 40/60/120}

_{TTFS/WO compare client vs deployment clocks and SL compares the step runner’s clock vs the client’s (NTP-synced in CI). WO ends at the last step body exit, the closest observable proxy for the final step-completion request.}
