A chronological companion to the ADRs: how the design came together, from
the first mental model and 2D prototype through the three data tiers, the
relative-pose broadcast, the layered WireGuard/SSH trust model, SQL as the
peer contract, offload and replication, and the end-to-end proof of concept.
Each chapter links straight into the relevant source and decision records.
Flagged as the recommended first read in the README.
