Read a board and its interactive diagram

A board's root Slack message is the anchor for the current diagram. It includes an inline PNG preview and an interactive HTML file, with History, Branch and Export controls. Show source is inside Export. The root message is refreshed when a new version becomes current; version replies retain the revision context in the thread.

Open the HTML file in a browser to pan and zoom, inspect provenance badges, read the Decisions panel, copy Mermaid source and browse History. On mobile, Slack may show HTML as code; download it and open it in a browser, or use the PNG preview.

For example, create a checkout flow, request a retry queue in the board's thread, review the proposal and apply it. Open History to revisit the retained versions, or select Retry queue in the HTML Decisions view to inspect its recorded source request. A diagram illustrates a design; it does not implement a retry queue.

The decision ledger is published separately in the background: as a standalone Canvas where Slack permits, or as a message in the board thread on Slack Free. Follow source-message links to inspect why a change was requested.

Channels can choose which files a new version posts with /arialine files both|png|html. The interactive HTML file and the PDF report use the board's language: a board created from a request in Spanish, for example, shows its buttons, dates and labels in Spanish.
