Description

After the reference boards were defined (20261006-0315-air-hub-reference-board-and-schematics) the owner said to start with the Pro first ("可以开始先做pro"). Taken as: carry Air Hub Pro (AH-20, Vanxoak HD-RK3506J core board) from the checked schematic to a first routed board, while the entry board waits for the SSD2351 temperature and price answers.

Acceptance criteria:

1. The Pro schematic no longer carries placeholders that block layout: the CMT2300A RF network follows the data-sheet reference circuit, the buck values follow the vendor design tables, and every part has a footprint that exists.
2. /srv/ybo/switch/air_hub_pro/ holds a placed and routed 4-layer board with a project-local footprint for the core board; DRC reports no unconnected items, no shorts or clearance errors and no schematic-parity differences; Gerbers, drill, position file, BOM and renders are exported.
3. P05-air-hub-design-reference-board.md records the board (stack-up, size, placement rules, DRC result, what the autorouted layout does not prove); the quality gate passes.

Notes

Plan: 20261006-0452-air-hub-pro-first-board

• complete: KiCad DRC on the routed Pro board: 0 unconnected, 0 clearance or short errors, 0 parity differences; ERC and verify_net.py pass for both projects; docs lint 230 pages 0 findings, docs:build and git diff --check pass.
