What

When a relayed request asks for tool permission on behalf of remote execution, the placeholder tool-use id it constructs is now a prefixed sha256 of the session id and the original id, truncated to 32 hex characters, instead of an arbitrary value. Only the remote-execution relay path is affected.

Evidence

sha256

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