Review Queue — Not Ready to Merge

@ktdreyer requested changes on March 4, asking to remove the entire ADR README table rather than updating it. The reviewer's rationale is that the fix went "in the wrong direction" — instead of removing the table as the linked issue intended, the bot updated it.

Also has line overlap with PR #832.

To unblock: Update the PR to remove the table entirely instead of adding ADR 0006 to it. Coordinate with #832 to resolve the file overlap.
