Written 2026-09-28, answered the same week by mesh-controller bdf965d and
c68d3a7, and never closed — so the mesh's own account said reach was declared
nowhere while three readers were reading it: the filter, the proxy's names, and
each authority's host policy. The resolution names them and what checks each.
What is left is retiring the older per-port keys the block replaces, which is
not a gap in what reach can say.
