Under the hood
Useful3 Signal4
Teammates can no longer even send a permission-mode change message; the shape was dropped from the schema.
What's wrong with this entry?
Anonymous. No account, no email.
What
The message shape teammates used to request a permission-mode change, carrying a mode and a sender, was deleted from the set of messages agents can exchange, so such a message can no longer be parsed at all.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
