# STEP 1409 — rei-scout × Akizuki 33 SKU catalog 提案 (2026-08-26)

## 起点

藤本さん directive 「1 から 5 を 順番に」 の (5) 実行。 STEP 1406 の 次段候補 (5) 「rei-scout `import-as-mcp` category に 25 SKU decision 記録可能化」 を hardware SKU 特有の 制約 (rei-scout 5 category は software MCP repo 想定) を 踏まえて 新 category 'hardware-wire-up' 提案 + JSON catalog format で export。

## 実装

### Data file

- `rei-aios/data/akizuki-wireup-catalog/candidates-2026-08-26.json` (~17 KB)
- Schema: `schema_version: 0.1.0-proposal`、 33 entry
- 各 entry field: id + source_step + interface + physical_quantity + part_number + vendor + akizuki_code + price_jpy + proposed_category + proposed_status + integration_status + safety_gate_required + note + optional (benchtop_pilot, safety_gate_reason)
- Summary: by_interface + by_safety_gate + by_benchtop_pilot

### 33 entry 内訳

STEP 1406 起源: 22 (BME280, SHT31, SHT40I, DHT20, ADT7410, LSM6DSV16X chip, LSM6DSV16X module, BNO055, GP2Y0E03, VL53L0X, VL53L1X, MAX31855, ESP32-DevKitC-32E, ESP32-WROOM-32E-N16, XIAO ESP32C3/S3, ESP-WROOM-02, XIAO BLE nRF52840, ESP32-C3-WROOM-02, ESP32-S3-WROOM-1, GT-502MGG-N, GU-502MGG-USB) + HC-SR04 (1 参考、 trigger/echo) = 23
STEP 1408 起源: 10 (SCD40, SGP40, MH-Z19C, MH-Z14B, TGS2450, TGS8100, MQ-2, MQ-3B, MQ-4, MG812)
計: 33 unique SKU

### Interface 集計

- I2C: 14 (STEP 1406 12 + STEP 1408 2)
- SPI: 2 (STEP 1406 = MAX31855 + LSM6DSV16X SPI mode)
- UART: 11 (STEP 1406 9 + STEP 1408 2)
- USB CDC: 1 (STEP 1406)
- Analog: 6 (STEP 1408)
- Digital (trigger/echo): 1 (HC-SR04 参考)

### SafetyGate 判定

- 不要: 28 SKU
- 要 (可燃性): 3 (MQ-2/MQ-3B/MQ-4) — 発火 hazard
- 要 (高温): 1 (MAX31855) — 熱電対 tip 火傷
- 加熱器 注意: 1 (MG812) — SafetyGate 対象外 だが 加熱器 過電流 discipline

### benchtop pilot 実装状況

- Pilot 実装済 (STEP 1407 v0.8): 3 (BME280, BNO055, VL53L1X)
- Pilot candidate (v0.9-alpha defer): 2 (SCD40, SGP40)
- Wire-up 候補 未着手: 28

## 新 category 'hardware-wire-up' 提案

**理由**: rei-scout 既存 5 category (import-as-mcp / port-to-rei / cite-only / defer / reject) は software MCP repo (owner/repo) 想定、 hardware SKU (akizuki/{code}-{part}) には 直接 mapping せず

**5-step spike template 提案**:
1. datasheet 再 verify (interface/voltage/current/range/calibration)
2. hardware 入手 (Akizuki 通販)
3. host MCU + wiring (I2C/SPI/UART pull-up + power decoupling)
4. driver + benchtop mock skeleton (STEP 1407 pattern)
5. 実測データ差替 (mock → real、 calibration curve validation)

## rei-scout local 反映 flow (提案、 藤本さん 手元)

```bash
# 1. catalog fetch (公開 URL 経由)
curl -o /tmp/candidates.json https://rei-aios.pages.dev/data/akizuki-wireup-catalog/candidates-2026-08-26.json

# 2. VALID_CATEGORIES に "hardware-wire-up" append (CATEGORIES.md 更新)

# 3. 各 entry loop で approve / defer
python -m scout approve akizuki/109421-bme280 --category hardware-wire-up --step 1407 --integration-status done "..."
python -m scout defer akizuki/106675-adt7410 --category hardware-wire-up "..."

# 4. progress 確認
python -m scout progress --category hardware-wire-up
```

## Honest scope (8 条)

1. **rei-scout 本体 未変更** = Downloads/rei-scout/ 一切 触っていない
2. **新 category 'hardware-wire-up' は 提案** = 実 追加 は 藤本さん judgment 待ち
3. **全 entry decision = 'proposed'** = 実 approve/deferred/rejected は 記録していない
4. **SKU identifier 独自 スキーマ** = 'akizuki/{code}-{slug}' は rei-scout 'owner/repo' と 形式互換だが 意味違う
5. **bulk import CLI 未実装** = 手動 loop で 個別 approve 必要 (v0.4 candidate)
6. **price_jpy 一部 null** = STEP 1406 fetch で 一部 price 未取得
7. **実 hardware 発注 全 SKU 未着手** = integration_status = 'not-started'
8. **novelty ゼロ** = 単 catalog 提案

## 次段候補

1. rei-scout 拡張 (藤本さん 手元、 CATEGORIES.md 更新 + 33 entry import)
2. bulk import CLI (`python -m scout import-catalog <json>` v0.4 candidate)
3. benchtop v0.9-alpha 化学 layer (SCD40+SGP40 mock)
4. 実 hardware 発注 pilot (BME280 ¥1,180 単品)
5. catalog 拡張 (光/カラー/UV/SpO2 sub-category recon + entry 追加)
