Recording-quality benchmark

Measured by node scripts/benchmark.mjs on the example suite (examples/) and its demo app. Rerun it after a change to recording or replay.

saffron-ai 1.3.3, 2026-11-05.

Measure Result
Stability: replays green on the untouched app 66 of 66 (100%), 22 scenarios × 3 runs
Flaky scenarios (green in some runs only) none
False greens on deliberately broken apps 0 of 8 (0%)
Recording quality (first attempt, held, time, cost) not measured in this run: --record records the suite with the agent, at AI cost

Broken apps, each a change that breaks the scenario it targets:
