EDA Bridge Standard: one way for an AI to drive every PCB tool - Commit

by adom

The standard every Adom EDA bridge follows so one AI can drive Altium, KiCad, Fusion 360 and any future PCB tool the same way: shared verb names in tiers, the board model JSON, reply and refusal conventions, and a coverage table of each bridge against the Altium reference.

standard 0.4.2, engine 0.1.1: stack_layers names copper layers by the stack entry's layer, or by place (In<n>.Cu), planes included, per 0.3.1 (altium-lane's patch from its vendored copy, #8)
