Replaces the proposal, which was wrong before it was written down. It presented A, B and C as the option space and concluded pod-to-pod was blocked; policy routing was available the whole time and is what moved pod egress and then pod-to-pod. The file recorded a blind spot and gave it the authority of a checked-in document.
Three of four classes are separated now, so this describes the built design rather than proposing one, and the PROPOSAL- name goes with it: which link each class uses, the rule order and why 980/981 match source and destination, where each table comes from, how the bird mesh renders itself from the API without repeating an address, and why the node's own CIDR is originated rather than read back from the kernel.
Management is the remaining class. Its levers are listed, along with the two approaches the owner rejected — with the caveat that the same reasoning which produced that list also called pod-to-pod impossible, so it is a record of decisions and not an analysis to trust.
Failure behaviour is stated because it is what makes the design safe to roll one node at a time: an empty table 48 falls through to main and pod traffic returns to VLAN 40, unseparated rather than broken.
bootstrap.sh's reference follows the rename; its point was always that the QEMU/Hetzner sites use two segments, not the homelab's split.
