Where cards come from

Every card remembers how it arrived:

Arrived	Foot of the card	Says
Placed by a person: pasted, typed, expanded or copied	Nothing
Dragged out of a widget	A list	“From the “Open bugs” list”
Sorted out of an inbox	A tray	“From the “Triage” inbox”
Placed by a rule	A spark	“Placed by rule: Pull requests beside their issues”
Asked for in a comment on GitHub	An @	“Added from GitHub by @kai”, linking to the comment

The glyph is tinted by what brought the card: blue for an inbox, amber for a rule, violet for a list, green for a comment. Point at it, or select the card, to read it.

When a card stops matching

What happens when the item no longer matches depends on how the card arrived:

• Placed by a person, from a widget, or asked for in a comment: nothing. A widget only ever copies, and a comment counts as its author placing the card.
• From an inbox or a rule: the card is marked, with a dashed edge and a band that says why, when the card shows it: “No longer matches: closed”, or “labelled bug”, or “not assigned to kai” (point at it for which inbox or rule). It’s never moved or removed.

The band offers:

• Keep: the card becomes an ordinary card, as if a person had placed it, and is never marked again.
• Remove: removes it from the board.

Marks come from GitHub’s webhooks for the card’s repository, and clear again if the item matches once more.
