+>
+> This file is the pre-backlog tracking mechanism. `NS-2` in the north star declares the
+> replacement: every backlog item is a Mosaic Backlog card projected from the YAML. That
+> model replaced this one and nobody retired the old file, so it kept reading as
+> authoritative while going stale.
+>
+> **Do not trust a status in this file.** Verified 2026-08-20: it was already behind the
+> code when it froze five weeks ago.
+>
+> Kept as a record of what was believed. Do not update it; update the YAML.
