Honor that choice without asking again. Otherwise, discover available profiles from `adom/pcb-design-rules` (or the selected bridge's rule-profile listing) and ask:++“Who would you like to manufacture this board? I can automatically load and verify the matching design rules—for example, InstaPCB, JLCPCB or PCBWay. You can also name another manufacturer or keep the current rules for now.”++Offer only manufacturers with available profiles as automatic-loading choices. Explain briefly that the choice affects trace widths, clearances, drills/vias and other fabrication limits. Do not silently default to InstaPCB or choose the smallest limits. If the user is undecided, retain and label the current rules as provisional; continue inspection while waiting, and defer manufacturer-dependent route generation or rule replacement until a choice is made.++Once selected, resolve the profile for the actual layer count, process and copper assumptions. Ask a focused follow-up only if a missing process choice materially changes the rules. Load it through the selected CAD bridge, export/read back the active rules, and report the profile and meaningful limits before routing. Preserve stricter electrical and user constraints. If no compatible profile exists, explain what is missing and obtain a supplied or authoritative profile rather than inventing one. Switching manufacturers later requires revalidation of the existing board and may require rerouting.+ # Electrical constraints before route generation  Start from the schematic, actual pad/net assignments, BOM and manufacturer requirements. A wiki overview can be wrong. Compare schematic and PCB membership; identify omitted parts, duplicate pads, alternative footprints and assembly variants. Preserve the original and previous demonstration as separate checkpoints.
