What

Failures in control handlers are now logged with the request subtype attached, so host and local logs distinguish a failed context-usage query from a failed model list, usage query, file rewind or event enqueue.

Evidence

"poll_event enqueue"

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