Deleting a board or stack left the workflow row pointing at nothing: Deck
keeps the orphaned cards readable until its DeleteCron purges them, so the
run kept failing on the move every few minutes, silently and forever.
- The controller now rejects boards and stacks that do not exist (or are not
the user's) on create and update, so no new broken row can be stored.
- The settings list marks affected workflows in red instead of showing a row
that looks healthy.
- The background job disables such a workflow and mails its owner once. The
mail ignores the notifyEmail flag: that one is about moved cards, this is a
notice that the automation stopped. It stays a one-off because a disabled
workflow is no longer picked up.
The check deliberately goes through StackService::findAll() rather than
BoardService::getUserBoards(): Deck injects the current user into BoardService
as a string frozen at construction, so in the job -- one process, many users,
a cached BoardService -- it would answer for the wrong user or for none, and
every workflow on the instance would have been disabled. findStackIds()
returns null only for a genuinely missing or forbidden board and throws for
anything else, so a Deck outage skips the workflow instead of killing it.
The mail named the card and the workflow but not what the card is about,
which meant opening Deck to know whether the move mattered.
The description is escaped explicitly: addBodyText() only calls
htmlspecialchars() when it has to derive the plain-text part itself, and we
pass both parts to get line breaks in the HTML body -- so escaping user
input is on us. Long descriptions are cut at 2000 characters.
Deck stores the description as Markdown; it is sent unrendered rather than
pulling in a parser for one mail.
Ports the standalone due-date cron script into a proper Nextcloud 34
app with a personal-settings UI, per-user workflow configuration
(source/target stack, assigned-user and label filters, email
notification), a TimedJob background runner, and Gitea CI pipelines.
