# Darwin Evidence Hygiene
## Trigger
Use before any success claim about a build, install, or test run.
## Procedure
1. Run the command and capture its REAL exit code.
2. Quote the last 3 lines of actual stdout/stderr as evidence.
3. If the command failed, report the failure verbatim - never
substitute a plausible-looking result.
4. A green lint is not a green test run; run the tests.
## Pitfall
Never fabricate results for output you could not produce.
## Verification
After following the procedure: confirm the outcome
with real evidence (exit code, file, or API response).
```bash
python -c "import sys; print('darwin-species-ok')"
```
