Gap #4 ("OPNsense automation + netem") was too coarse -- broke it into what
it actually is: (a) network substrate DONE (modules/mesh-link), (b) the edge
VM/image BLOCKED on the deferred domain module with no image source chosen,
(c) OPNsense's own routing/firewall config NOT STARTED with no mechanism
picked (config.xml is untouched by the libvirt provider), (d) tc netem WAN
simulation is a separate OS-level mechanism with no Terraform-native
equivalent, blocked on an unruled D-100 parameter decision before it can even
be scripted. Same breakdown mirrored into opentofu/README.md's deferred-items
list and the companion visual tracker.
