## Method notes

- Key events were dispatched to the renderer frame as keydown, keypress and keyup with explicit which/keyCode, because p5.js reads `which`; the first attempt without it produced no change and is not counted as a test.
- Transparency: the published label follows the level index in reverse (1 = Very high); cross-tabulation of label against level and alpha value is recorded in S03.

## Validator

Command actually executed, from the extracted pack root:

```sh
python3 scripts/validate_series_essays.py submission/rotor-by-sebastian-brocher-cryptoarte
```

Supplied validator identity: `scripts/validate_series_essays.py` as distributed in `claude-remaining-10.zip`, SHA-256 `f7b561578fa3ece1680ef69a2b8b484c660ca3d0b17275df10c6ff2026f09fdc`. No substitute validator was used and no check was altered. A structural pass is not by itself completion; the checks report above is the substantive report.
