When auto-mode is active and a classifier call completes after the permission mode changes, Claude now falls back gracefully to manual approval with a clear message: "Permission mode changed while the auto-mode classifier call was queued — falling back to manual approval under the current mode".
Previously this edge case could lead to unexpected behavior.
Evidence
New warning string (search for "Permission mode changed while the auto-mode classifier call was queued")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
