Context

Revised 2026-10-22 after a second pass requested by the owner, with emphasis on the P05 Switch line, which changed substantially between 2026-10-14 and 2026-10-22 (tasks 20261014-2350, 20261015-1500, 20261019-1200, 20261019-1500, 20261020-1000, 20261020-2336, 20261022-0322, 20261022-0420).

The business-plan pair (business-plan.md, business-plan.en.md, v2.1) was last restructured on 2026-09-14 and touched once on 2026-09-28. The product plan (product-plan.md, v1.9) is the governance summary the business plan points to, but its P5 section still records the Switch line as of 2026-09-29…10-12 and has not followed the Switch documents' 2026-10-19 "current design only" rewrite. The two files therefore drift from the product packages in different ways.

Current Switch line (source of truth: bizplan/product/switch/)

Product	Current state
Air 2 / Air 4	$59; CR2450; nRF54L15 BLE (Zigbee/Matter storage reserved, not in v1); 433 variant on TI CC1310; 86-type plate, ≤12 mm; IP54, −20…+60 °C

Key Box 36 (new, 2026-10-20…22, two tasks still in progress)	External-pushbutton control box: 36 inputs, 72 low-side lamp outputs, 4× AMPSEAL 35, NMEA 2000 Micro-C on an isolated CAN2 (N2K-ready, stack and certification not in v1), RS-485, 8 analog inputs (0–190 Ω / 4–20 mA), IP67 mated, −25…+70 °C; no price yet
Air Hub (AH-19)	$59; RK3506G core board; EFR32MG21 (BLE/Zigbee/Thread by signed image); ESP32-C6-MINI-1-N4 for Wi-Fi/config; Ethernet; BOM $33.0–42.2 vs ceiling $19.18–22.13 (over)
Air Hub Pro (AH-20)	$119; RK3506J core board; same radios + CMT2300A 433 MHz; BOM $34.6–46.7 vs ceiling $38.68–44.63 (within at the low end)
Air Hub Mini (AH-21)	$49; ESP32-C6-MINI-1-N4 as sole controller, no Linux, no Ethernet (Wi-Fi only); BOM $22.2–27.5 vs ceiling $15.93–18.38 (over)
Air Hub family, common	Commercial grade: IP54 by gasket and conformal coating, no sealed M12/DT connectors; USB-C PD primary supply (Hub/Pro 9–12 V, Mini 5–12 V) plus M8 4-pin YBO harness 9–36 V secondary; −20…+60 °C; Rust host software; M8 proposed as the family YBO-bus connector (decision 2026-10-20, adopted on Air Hub only)

A. Business plan drift

1. Hub is no longer a product (merged into Mate 2026-09-12/13); the plan still separates Hub and Mate in §4.1, §4.2, §4.4, §4.5, §4.6 and §9.
2. The Switch line is reduced to "Key and Air". No Air Hub family, no prices, no Key Box 36. The standalone-kit sentence (third-party N2K digital switching / Modbus) is the 2026-08-27 direction, now an unfrozen extension (product-plan §6 item 11); the off-boat form is P09 Control (T2).
3. Control (T2) and View (T3) are missing from the matrix.
4. Air Hub and Air Hub Mini exceed the landed-cost ceiling; not disclosed in §11/§12.
5. Refit Starter/Pro prices and the €2,400 illustrative ASP derive from the retired Core S/M/HD prices.
6. Team size stated three different ways (§8, §11, product-plan staffing).
7. Studio row ("fully open", "frontal strike") contradicts the governed-configuration stance of §1/§7/§12; Mate's "fully familiar within 1 hour" is stated as fact, product plan marks it (t).
8. Header body line v2.1 — 2026-09-14 vs frontmatter 2026-09-28; funding rounded differently in §1 and §11; stale link label research/07-... in §4.1.

B. Product plan drift (Switch and platform rows)

9. P5 "Air Hub 平台方向" row: Mini still "ESP32-C6-WROOM-1 … W5500 以太网"; supply still "12/24 V 标称、8–32 V"; no USB-C/M8, no commercial IP54; carries the full selection history (SSD202D … MA35D1, SigmaStar drop) that the Switch documents removed on 2026-10-19.
10. P5 "Air Hub 定位" says "需要 Linux" for the whole hub; Mini has no Linux.
11. P5 Key subsection has no Key Box 36.
12. §5 cost row: Air Hub $31.4–42.3 and Mini $23.8–30.8 are superseded by $33.0–42.2 and $22.2–27.5; Pro is now within its ceiling at the low end.
13. §6 item 4 still says Air Hub split into Air Hub and Air Hub LR (withdrawn 2026-09-29); §6 item 3 (YBO bus connector, M3) does not reflect the 2026-10-20 M8 draft decision.
14. §1 platform table: MCU row recommends STM32G0B1CE for Key/Air Hub (Key moved to ESP32-C6 2026-09-28, Air Hub is RK3506 + ESP32-C6); wireless row says Air Hub Wi-Fi is a separate extension (it now has Wi-Fi on all three and Ethernet on two); "Hub 计算" row and RS-485 row still name Hub; T0 tier row and staffing name Hub; §3 dock Wi-Fi row says Air Hub joins Wi-Fi only with an extension.
15. Body version line reads v1.2 — 2026-09-14 vs frontmatter v1.9 — 2026-10-14.

C. Status (for the owner, not a wording fix)

16. M1 = October 2026. Most engineering so far has gone into the T1 Air Hub (three products, schematics, routed boards, handover package) and, since 2026-10-20, Key Box 36, while the T0 Core is still waiting for supplier terms at the M3 gate.

Out of scope, recorded as follow-ups: Hub references in open-questions.md (CTL-O-01, item 2 of the field-wiring list), compliance-matrix.md (Mate hardware row label "Hub", remote row, quote list) and ppt-build-guide.md; open-questions.md still lists AIR-O-09 as open although the product plan records it closed 2026-09-29.

Concurrency: Key files (bizplan/product/switch/key/) carry uncommitted changes from tasks 20261022-0322 and 20261022-0420, still in progress under another session; Air Hub task 20261020-1000 is also in progress. This plan does not edit any product-package file.

Proposal

Part A — business-plan pair (zh + en in lockstep, v2.2)

1. Replace Hub with Mate throughout; merge the §4.6 Hub and Mate rows into one Mate row (hardware side: i.MX93 main controller, N2K/MFD interoperability, Wi-Fi/WAN/4G; software side: app, cloud, vessel management, handover, tiers). §9 row becomes "Mate / Switch wireless".
2. Rewrite the "Key and Air" matrix row as the Switch line: Key ($149, wired, BLE service link only), Key Box 36 (drives existing marine pushbuttons; price TBD), Air ($59), Air Hub family ($49 Mini / $59 / $119 Pro; Zigbee/Thread coordinator capable). Replace the standalone-kit sentence: Air + Air Hub run without Core; the off-boat form is P09 Control (T2), not a launch market. In §4.3 refit, mention Key Box 36 as the way to keep existing helm pushbuttons.
3. Add Control (T2) and View (T3) one-line entries; add the tier to each matrix row.
4. §11 unit economics and §12 risks: Air Hub and Air Hub Mini over the landed-cost ceiling (figures and link to P05-air-hub.md §2.1, tracked under AIR-O-03); Pro within at the low end.
5. Mark Refit Starter/Pro and the €2,400 ASP as targets carried over from the retired Core price list, pending product-plan §6 1f.
6. One staffing figure consistent with product-plan §2 and the budget line.
7. Studio: "governed open configuration", drop "frontal strike". Mate: 1-hour handover marked as a target.
8. Fix header line, funding rounding and the stale link label.

Part B — product-plan (governance summary of the Switch line and platform rows, v1.10)

9. Rewrite the P5 "Air Hub 定位 / 平台方向 / 目标 / 扩展" rows to the current state only, matching the 2026-10-19 Switch rewrite: three products with core board, radios, uplinks, supply (USB-C PD + M8 9–36 V), commercial IP54, Rust host, Linux only on Hub/Pro. Selection history stays in the Air Hub evaluations and changelog.
10. Add a Key Box 36 row to the Key subsection, limited to the facts already in Key spec §2.1 and linking there; price "TBD".
11. Update the §5 Switch cost row to the current BOM figures and add Key Box 36 as "TBD".
12. §6 item 4: drop Air Hub LR wording, state current locks. §6 item 3: note the M8 draft decision adopted on the Air Hub family, family-wide acceptance still open at M3.
13. §1 platform table: MCU row (Key ESP32-C6-MINI-1; Air nRF54L15 / CC1310; Air Hub RK3506 + ESP32-C6), wireless row (Air Hub family Wi-Fi/Ethernet built in), "Hub 计算" → Mate hardware, RS-485 row, T0 tier row, staffing and §3 dock Wi-Fi row: Hub → Mate.
14. Fix the body version line; add a version note.

Plus docs/changelog.md entry. No new figures: every value is copied from a product spec, commercial-model.md or an existing decision record.

Risks

• Key Box 36 is still being specified in two in-progress tasks; Part B quotes only stable facts and links to Key spec §2.1. If those tasks change the box, the product-plan row must follow. Implementation starts after they are marked complete, or quotes only the box's role.
• Air Hub task 20261020-1000 is in progress; Part B copies figures from the current committed spec and re-checks them before finishing.
• The English business plan can drift from the Chinese one; edited in one pass, section by section.
• Disclosing the Air Hub cost gap in the business plan makes a weakness visible; the plan's own rule is to disclose gaps.

Scope

Three files: business-plan.md, business-plan.en.md, product-plan.md, plus tracking (docs/changelog.md, task, plan). About 30–40 changed lines per business-plan language and 15–25 changed rows in the product plan. No product-package file is edited.

Alternatives

• Part A only: smaller, but leaves the business plan pointing to a product plan that contradicts the Switch specs.
• Also fix open-questions.md, compliance-matrix.md, ppt-build-guide.md: about three more files; can follow as a separate task once Part B is done.
• Deeper business-plan rewrite (investor order, shorter summary): not proposed; the structure was set deliberately by BIZ-004…007 and the problem is content drift.

Annotations

Open question for the owner (does not block the proposal): should the roadmap and tier table acknowledge that the Air Hub and Key Box 36 are ahead of the T0 Core, or should Switch hardware work pause until the M3 Core supplier gate? The proposal records current status only; it does not re-tier products.
