 it, not because of a different policy. If you are copying an Aere Network component and want to know

+## The `anchor/` tree, measured the same way (added 2026-08-27)
+
+The post-quantum anchor overlay published on 2026-08-11 brought 77 files under `anchor/`.
+45 of them carry `Copyright contributors to the AERE Network.` and are new work. The
+following 27 carry an upstream copyright line and are therefore Apache-2.0 material
+redistributed under section 4: each one is **modified by Aere Network** (that sentence is
+the section 4(b) notice of changed files), and each keeps its original notice per 4(c).
