Description

A reviewer listed eight items against the Air Hub documents. Items 1, 2 and 7 (3.3 V inductor count 2 / 1, key count 3 / 4, WROOM-1 footprint) quote the 2026-10-09 SSD2351 revision; the current pages already state one inductor, three keys on the Linux carrier and one on Mini, and the MINI-1 module.

Acceptance criteria:

1. The Mini cost table no longer counts a watchdog; the spec and design appendix figures follow.
2. The Mini W5500 magnetics follow the WIZnet WIZ550io reference schematic (RX pair AC-coupled by 6.8 nF, terminations to a 10 nF midpoint on the RCT, TCT through 10 R with 22 nF); the Mini is rerouted with 0 unconnected and 0 clearance errors. Schematic text states 9-36 V and the title blocks carry the board revision (Linux carrier C, Mini B).
3. The handover README lists RF verification, production connectors and enclosure, and the core board supply, quote, thermal and 128 MB memory items as open; the MINI-1 footprint check is recorded as verified.
4. Quality gate passes: bun run docs:lint && bun run docs:build && git diff --check.

Notes

No plan file. The reviewer's item 6 found the mismatch; the owner asked to redo the schematics. W5500 reference: WIZnet WIZ550io v1.2 schematic. MINI-1 land pattern: Espressif ESP32-C6-MINI-1 datasheet §11.1.
