The info-media marker moved to meta/info.yml one commit ago, and this rule is
where the reason it could not move earlier was written down: a comment-only
info.yml parses to an empty document, which the schema lint used to reject. That
obstacle is gone, so the docstring now states a justification that no longer
holds, and the two video-related exemptions sit in different files for no reason
a reader can reconstruct.
So the marker is read from info.yml, the failure message names info.yml, and the
docstring says why the marker lives there rather than why it cannot. No role
opts out of this rule today, so nothing under roles/ changes and the move cannot
break in either direction.

The root-README overview renders a Video link per role and a reader following it expects a demo, but 26 of the 62 entries addressed a channel, a playlist or a product page: youtube.com/@zammadhq, /channel/UC..., framatube.org/c/mobilizon/videos, pgadmin.org/videos. None of those can be embedded and none shows the product without a second click.
Each replacement was resolved through YouTube's oEmbed endpoint, which returns the real title and channel, so a candidate could be checked rather than assumed. That caught a supposed LibreOffice intro published by an unrelated channel, a Discourse overview belonging to a hosting vendor, and a Zoom video answering 403 with embedding disabled. Fourteen of the new entries come from the vendor itself and two are PeerTube.
The reachability half needed the same endpoint for a different reason: YouTube answers a removed video with HTTP 200 and a Video-unavailable page, so a plain fetch proves only that YouTube is up, while oEmbed answers 400. Measured both ways before relying on it.
The check is external because reachability needs live HTTP, and like its siblings it reports an unanswered probe as unverified rather than failing, so a firewalled runner cannot redden a good URL. Only the shape is asserted, because that is a repository fact.
README.md follows rather than leads: overview.py renders the Video column from this field.
