The unmet-dependency and ephemeral-disabled pre-dispatch gates re-run on every
dispatch attempt for a blocked task but only change state on the first, so every
later pass re-logged the same line at default level and drowned the log pane.
Route both through logDispatchBlockedOnce: first block per task/reason logs at
log(), identical repeats drop to debug() (FUSION_DEBUG=executor), a changed
reason logs again, and the marker clears when the gate passes.
