## Method notes

- Generator cross-check: the class Z arithmetic equals Return's rnd() and Mental pathways' random_dec() (both retrieved this session).
- The trusted Space key sent by the automation tool reported empty `key` and `code` in the page, so the program's `e.code == "Space"` test failed. A constructed keypress with code Space was used; this is disclosed wherever controls are reported.
- Live tempo values (142, 178, 118, 171) equal the reimplementation's predictions for the four hashes; live shape counts on three rooms equal the predictions exactly.
- Sale duration: 2021-08-28T19:18:14Z minus 2021-08-28T19:00:00Z = 18 min 14 s.

## Validator

Command actually executed, from the extracted pack root:
