DEIs 87f75dd98f feat(plant): fleet map page with GPS-denormalised vehicles, clustering, and tile switcher
Adds /dashboard/plant/map: a Leaflet view of every vehicle scanned from
the MEGA Clock kiosk, plotted at its last known position.

Schema
- vehicles.last_latitude / last_longitude / last_scanned_at /
  last_location_accuracy_m denormalised off fuel_logs so the map page
  renders every vehicle in a single query. Same best-effort pattern as
  attention_dismissed_at; updated by /api/clock/vehicle-scan after every
  successful scan. PB init defaults new number cols to 0 (not null) —
  filter uses 'last_latitude > 0 || last_latitude < 0' to mean 'real fix'.
- Indexed via idx_vehicles_last_scanned.

Map UI
- Custom SVG markers per unit_type: car silhouette for fuel, tractor
  silhouette for plant, 24x24, drop-shadowed.
- Clustering via react-leaflet-cluster over Leaflet.markercluster.
  Cluster icons colour-ramp with size (green->sky->amber->rose) and
  scale 32->54px.
- Three-button base-layer switcher: Street (OSM), Dark (ESRI Dark
  Gray Canvas — CartoDB watermarks tiles without a key), Satellite
  (ESRI World Imagery). Last choice persists in localStorage.
- Site pins: small purple map-marker divIcon, click flies the map to
  zoom level 15.
- Empty-state is a floating chip on the map rather than a full-page
  card so the map is always visible.

APIs
- /api/clock/vehicle-scan: stores the GPS fix on the fuel_logs row
  AND denormalises onto the vehicle when present; missing-coord
  scan leaves last_* untouched.

# MEGA INFRASTRUCTURE — Operations Dashboard
A **Next.js 16 + TypeScript + Tailwind v4** operations dashboard for a
South African civil construction company, backed by **PocketBase**.
Tracks, per construction site: contracts, employees & timesheets,
vehicles (fuel + plant), fuel logs, plant hour meters, fixed costs,
income claims, purchase orders + line items, and delivery notes with
OCR-driven receipting. Includes an LLM chat ("Ask") with a read-only
tool layer over the same data, and a read-only MCP server.
> **Default login PIN is `2468`.** Change `NEXT_PUBLIC_APP_PIN` in
> production. Append `?demo=1` to any URL to bypass the PIN during
> development.

## Quick start
```bash
cp .env.local.example .env.local
# edit NEXT_PUBLIC_POCKETBASE_URL, POCKETBASE_ADMIN_*, N8N_*
npm install
npm run dev # next dev -H 0.0.0.0 -p 6004 --webpack
```
Production build / start:
```bash
npm run build # icons + og-image + next build --webpack
npm run start # next start -H 0.0.0.0 -p 3000
```
Docker / Coolify: see [`docs/COOLIFY.md`](./docs/COOLIFY.md) and the
[`Dockerfile`](./Dockerfile).
MCP server (stdio, read-only):
```bash
npm run mcp # uses the PocketBase creds in .env.local
```

## Modules
The sidebar lists seven modules. Each is documented in
[`docs/modules.md`](./docs/modules.md).
| Path | Module | What it shows |
| --- | --- | --- |
| `/dashboard` | Overview | KPI tiles, fuel-attention rail grouped by site, every site summary |
| `/dashboard/sites` and `/dashboard/sites/[id]` | Sites | Per-site profitability, burn, P&L, payroll, weekly & monthly trends |
| `/dashboard/employees` | Workforce | Per-employee hours, rates, weekly trend, casual-matrix import |
| `/dashboard/plant` and `/dashboard/plant/[vehicleId]` | Plant & Equipment | Hour-meter history, weekly logs, billable rate |
| `/dashboard/plant/map` | Fleet Map | Live Leaflet view of every vehicle's last scanned position |
| `/dashboard/fuel` and `/dashboard/fuel/[vehicleId]` | Fleet & Fuel | Variance per log, over-limit flags, dismissable attention |
| `/dashboard/purchasing` and `/dashboard/purchasing/[poId]` | Purchasing | Every PO, DN fulfilment %, OCR exception inbox |
| `/dashboard/chat` | Ask | Read-only LLM chat with the same metrics the dashboard uses |
---
## Documentation
| Document | What's in it |
| --- | --- |
| [`docs/architecture.md`](./docs/architecture.md) | Runtime topology, the two PB clients, rendering model, auth model, build/deploy |
| [`docs/data-model.md`](./docs/data-model.md) | Every PocketBase collection, fields, relations, the `project_code` denormalisation, indexes, API rules |
| [`docs/modules.md`](./docs/modules.md) | One section per dashboard module — what it reads, computes, lets the user do |
| [`docs/data-flows.md`](./docs/data-flows.md) | End-to-end ingestion pipelines with sequence diagrams (timesheets, fuel, plant, PO, DN) |
| [`docs/api-reference.md`](./docs/api-reference.md) | Every API route — method, auth, request/response, error cases |
| [`docs/operations.md`](./docs/operations.md) | Env vars, scripts, tests, feature flags, deploy / smoke test |
| [`docs/multi-site-assessment.md`](./docs/multi-site-assessment.md) | **The main deliverable** — will this app hold up at 50 sites? Where does it break, and what to fix in what order? |
The `docs/superpowers/` directory has older design notes; treat as
historical, not authoritative.

## Tech stack
- **Next.js 16** (App Router, modified build — see `AGENTS.md`)
- **React 19** + **TypeScript 5.7**
- **Tailwind v4** (via `@tailwindcss/postcss`)
- **PocketBase 0.27** (PocketBase v0.22+ schema shape, see
`scripts/pb-bootstrap-schema.py`)
- **SheetJS** (xlsx) + **PapaParse** (csv) for imports
- **Recharts** for charts
- **Vitest** for tests
- **`@ducanh2912/next-pwa`** (Webpack-only — `next dev`/`build` pass
`--webpack` to support it)
- **Anthropic** or **MiniMax** as the chat LLM provider

## Tests
```bash
npm run typecheck # tsc --noEmit
npm run test:run # vitest run
```
The metric helpers under `src/lib/metrics/*.test.ts` pin every
computation the dashboard exposes. Run after any change to the
financial roll-up.
