Pin a Slack message to propose a diagram change

React with 📌 to a message to propose a change to an existing Arialine diagram in the same channel. A 📌 inside a board's thread always targets that board. Arialine reads the surrounding conversation so a short reply such as “yes, use the queue” can be understood in context, and shows its working status in the thread while it drafts the proposal.

If more than one board could match, Arialine asks you to choose; it does not guess. The proposal card shows the suggested change and offers Apply, Edit proposal, or Dismiss. Applying creates a normal new version and credits the pinned message as the source. Editing lets you correct the wording before review. Dismissing leaves the board unchanged.

A 📌 reaction proposes a change to an existing board; it does not create a new board, and it never targets boards in other channels. If the channel has no board yet, Arialine replies in the thread so you know to create one first. You can also address Arialine directly when you want to create a board or request an edit.
