For consistency with other workflows (e.g. .github/workflows/copilot-setup-steps.yml), consider using the block mapping form for triggers (on: with an indented workflow_dispatch: key) instead of the scalar shorthand. This also makes it easier to add additional triggers later without rewriting the section.

Suggested change

	on: workflow_dispatch

	workflow_dispatch:

The comment about commenting out the on property causing emails to be sent is a bit ambiguous and may be hard for future maintainers to interpret. Consider rewording it to describe the specific failure mode (or linking to the relevant issue/incident) so it’s clear why this workflow is workflow_dispatch-only.

Suggested change

	# just commenting "on" property causes emails to be sent to everyone
	# Keep this workflow manual-only. Re-enabling the pull_request trigger above
	# caused GitHub Actions notification emails to be sent broadly for those runs.
