# UNDERSTAND FIRST — AI Pollution Source Tracking Subcontract (Vendor TBD ↔ Thailand)

> **Your role:** Product / Application Engineer, Thailand side. **Subcontract** (per-engagement, not principal).
> **Read top → bottom = priority order.** Start at ①.
> Owner: Phatchara · Created 2026-06-27 · Domain: AI-IoT / Environmental Monitoring
> **Status: FROZEN — exploration only · no external trigger yet** (mirror of ESS pattern)

## 0. Your one-line mission
Translate **Thai air-quality field requirements → optimized, code-compliant monitoring system spec → hand to vendor → validate what comes back**.
You are the **technical bridge**, not the dealmaker. Where products vary by environment / pollutant profile / urban density / regulatory regime — that re-spec is *your* value.

---

## ① Lock YOUR position — do THIS before pouring hours
- Mirror ESS-Yotai pattern: **frozen until trigger event** (boss channel / customer ask / role written).
- **Risk:** doing unpaid spec work for a deal that may never happen, with no agreement.
- **Ask boss/relative:** if deal closes — am I employee / consultant / per-project? Rate? Do I own the sizing tools, deployment density models, AI training-data labels I build (IP)?
- **Hedge:** bias prep toward **portable knowledge** (③ ⑤) — environmental-monitoring sizing & Thai-PCD compliance is valuable even if this vendor deal dies.

---

## ② Verify Vendor — don't trust the marketing deck (PENDING OCR)
Raw sources in `00_sources/` are **image-scanned PDFs** — text not yet extracted. OCR pending.

| TODO | Method | Output |
|---|---|---|
| OCR all 7 PDFs | NotebookLM upload (preferred, zero cost) OR Tesseract local | text in `01_vendor-diligence/raw-text/` |
| Identify vendor entity | from logo/footer in OCR output | vendor name + Chinese registration |
| Verify financial claims | gov listings + audited financials demand | trust matrix (like ESS §② Yotai) |
| Check name-collision | search Chinese registry for similar names | confirm which entity boss deals with |

**Demand 3 docs (filters out fakes):** (1) business license + unified social credit code · (2) latest audited financials · (3) commissioning cert / letter of acceptance for any claimed reference project.

## ③ Thailand localization = YOUR MOAT (highest technical leverage)
Chinese spec assumes China climate + Chinese regulatory regime. You own the re-spec for Thailand.

### Climate derating
- Ambient **35–40 °C** (China base 25 °C), RH **70–90 %**, coastal salt, monsoon, dust → sensor drift, electrochemical cell degradation, calibration cycle shorter.
- **IP65+ / C5-M corrosion** for outdoor stations.
- Rainy season (May–Oct) → enclosure water-ingress + lightning protection.
- Urban heat island (BKK metro) → station siting near asphalt = +5°C bias.

### Pollutant profile (Thailand-specific)
- **PM2.5 dominant** (agricultural burning Jan–Apr · transport · construction).
- **O3 + NOx** (urban traffic, BKK/Chiang Mai).
- **SO2** (industrial belts: Map Ta Phut, Rayong, Saraburi).
- Less coal-fly-ash than China north → different AI source-attribution training set needed.

### Regulatory regime
- **Pollution Control Department (PCD / กรมควบคุมมลพิษ)** — owns reference network (Air4Thai).
- **TIS (มอก.)** — sensor certification.
- **Local administrative orgs (อปท.)** — deployment permits.
- **BOI / IEAT** — industrial estate compliance monitoring.
- IEC/ISO sensor performance: **EN 14211 (NOx), EN 14212 (SO2), EN 14625 (O3), EN 16450 (PM)** — vendor must meet equivalency or US-EPA designation.

### Network / power / data sovereignty
- **3G sunset · 4G/5G + NB-IoT** for remote stations.
- **PEA/MEA 230V single-phase** at most pole sites.
- Solar + battery for off-grid → ties to ESS engine sizing (cross-engine integration later).
- **PDPA**: AI-derived attribution data linked to geo coords = personal data if pointing at specific industrial sites — legal review.

## ④ Economics — sanity-check for the boss
Landed cost (FOB + duty + DG freight if Li battery + install + commissioning) · customer **payback** depends on use case:

| Customer | Revenue model | Payback driver |
|---|---|---|
| Industrial estate (IEAT/BOI) | Compliance monitoring fee | Avoid regulatory fine + community grievance |
| Local govt (BMA, จังหวัด) | Public-health budget | Citizen dashboard + smog season response |
| BOI factories | ESG reporting | Carbon/air disclosure for export markets |
| Property developer | Premium positioning | Air-quality differentiator (condo sales) |

**Competitor scan:** AirVisual/IQAir (consumer + pro), Aeroqual (NZ), Acoem (FR), Vaisala (FI), Met One (US), domestic: ENRES, RTAS. If we can't beat sensor accuracy + AI source attribution + price vs them, deal has no edge.

---

## ⑤ Your deliverable engine (build once, reuse forever)
1. **Site-survey intake form** — pollutant priority, station density, power available, mounting (pole/rooftop/fence), comms (4G/NB-IoT/Eth), reference-station distance, target accuracy class.
2. **Deployment density calculator** — area km² × target spatial resolution × sensor uncertainty → station count + siting heatmap.
3. **AI source attribution validation protocol** — back-trajectory + emissions inventory cross-check.
4. **Spec → Vendor → validate** loop — turn intake into spec sheet, send to vendor engineers, check return against ③.

## ⑥ Build roadmap (mirror ESS, but FROZEN until trigger)

## ⑦ Trigger to unfreeze (per ESS pattern)

Same gate as ESS:
- A. Boss/relative channel — concrete deal motion (vendor MOU, customer LOI)
- B. Real customer — IEAT estate, BOI factory, BMA dept asking for proposal
- C. Role written — subcontract terms in writing (rate · IP · scope)

**Until ≥1 triggers fire → DO NOT pour hours.** Read sources, OCR, but defer all sizing tools + MVP build.

---

## ⑧ Cross-engine integration (defer · note for later)

This subcontract domain **overlaps** with operator AI-IoT engine portfolio:
- **Solar + battery for off-grid stations** → ESS engine sizing tools reusable.
- **NB-IoT / 4G IoT firmware** → PlatformIO engine pattern (ESP32 fleet).
- **SBOS intel pipeline** → harvest air-quality regulatory news + PCD tenders.
- **Synapse knowledge ops** → store deployment-density learnings as durable memory.

Integration deferred until subcontract advisor work proves out (per operator note 2026-06-27).

---

> **Last words:** Mirror of ESS UNDERSTAND-FIRST. Frozen-mode default. Unfreeze only on confirmed trigger. Portable-knowledge bias = even if this vendor dies, Thai air-quality monitoring market knowledge stays valuable.
