The tests/ directory held 50 laboratory programs and no tests. They model channels, run hundreds of repetitions and write CSV, PNG and reports; calling that a test suite blocked introducing a real one, because any pytest run would have collected the labs and re-executed every experiment. - move all 50 lab programs to experiments/ with git mv, preserving history - rewrite the 38 cross-imports between labs from tests.labNNN to experiments.labNNN - leave tests/ empty for actual fast checks of protocol/ - point quick_gate and the hook at the new layout and add experiments/ to the syntax sweep - update the paths quoted in the Lab042 specification and the verifier agent definition This also defuses the import-time work finding without touching 41 files: the labs still create directories and write files on import, but nothing imports them now except the gate, which does so deliberately. Gate passes: syntax clean, protocol imports, 15 lab modules import, 2 functional suites run. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Русский текст, символы, байты и кодировка UTF-8.

Цель:

1. Увидеть разницу между количеством символов и количеством байтов.
|

2. Посмотреть, сколько байтов занимает каждая русская буква.
|

3. Восстановить исходный текст из байтов.
