What it does

Behaviour that must not change

The full behaviour contract lives in docs/contracts/core_groupguardian.md.

How to verify it

Per-event bot skins

one process serves every skin; cb_core/skins.py adds the two behavioural forks v1 keys on is_alternate_bot (intro animation, fun-override flair) plus the per-skin asset override tree; all 5 personas configured (0007). Handler packs landed with x_custom_commands - see cb_gateway/packs.py
