How we tested

13 open-source repositories the system had never been tuned against — axios, chalk, click, date-fns, express, fastapi, flask, hono, markupsafe, pydantic, requests, rich, and zod. Three real bug issues each — no feature discussions.

For every issue, the same Claude Code agent located the relevant code twice: once with only grep + file reads, once with Lettuce. Each arm ran 4 times; the median is reported. Tokens come from the agent's own usage meter.
