Arialine maintains a Slack Canvas decision ledger for each board. It is a secondary, readable history of the diagram's versions and decisions, linked to the Slack discussion that caused each change.The ledger shows the version timeline, summaries, authors, dates, rendered diagram images, and source-message links. Use it to review how the board evolved and why an element or connection exists.The current diagram remains available as Slack files on the board root and version replies. The ledger is the narrative record; it does not replace the current diagram or its Mermaid source.

Each board keeps a Slack Canvas ledger with its visual timeline and linked decision history.
