-# Extrudex
-
-> Filament inventory and print tracking system for CubeCraft Creations.
-
-Extrudex replaces Spoolman with a fully custom solution built for Joshua's 7-printer fleet. It tracks spool stock, per-print material consumption, and cost-of-goods — with a touch-optimized kiosk interface on a Raspberry Pi 5.

-## Domain Model
-
-### Materials (normalized taxonomy)
-
-| Entity | Description |
-|---|---|
-| `MaterialBase` | The base material type — PLA, PETG, ABS, ASA, TPU, etc. |
-| `MaterialFinish` | Required. Surface finish — Basic (default), Matte, Silk, Sparkle, etc. |
-| `MaterialModifier` | Optional. Composite fill — Carbon Fiber, Glass Fiber, Wood, etc. |
-
-**Rules:**
-- `MaterialFinish` is required — every spool must have one. Default is `"Basic"`.
-- `MaterialModifier` is optional — plain PLA has no modifier.
-
-### Consumption calculation
-
-```
-grams_used = mm_extruded × filament_cross_section_area × material_density
-```
-
-Grams are always derived, never assumed from printer telemetry directly.
-
-### Printers
-
-| Type | Integration |
-|---|---|
-| Bambu Lab (×5) | MQTTnet with TLS |
-| Elegoo Centauri Carbon | Moonraker REST + WebSocket |
-| Elegoo Saturn (resin ×2) | Manual / future |
-
-AMS units and slots are modelled as `AmsUnit` → `AmsSlot[]` → `Spool`.
-
----
-
-## Key Design Decisions
-
-1. **Spoolman rejected** — Full custom system for data model control and workflow flexibility.
-2. **`"Basic"` not `"Standard"`** — Default `MaterialFinish` value is `Basic`.
-3. **`MaterialFinish` is required** — No null/optional finish state allowed.
-4. **`MaterialModifier` is optional** — Not every spool has a modifier.
-5. **Derived consumption** — Grams calculated from mm × density, never assumed.
-6. **Push over poll** — SignalR and MQTT preferred over periodic polling.
-7. **Snake_case PostgreSQL** — All database identifiers follow this convention via EF Core.
-
----
-
-## Getting Started
-
-### Prerequisites
-
-- .NET 8 SDK
-- Node.js 20+
-- Docker + Docker Compose
-- PostgreSQL (or use the dev compose stack)
-
-### Backend
-
-```bash
-cd backend
-
-# Restore and build
-dotnet restore
-dotnet build
-
-# Apply migrations
-dotnet ef database update
-
-# Run API (dev)
-dotnet run --project API
-```
-
-API runs at `http://localhost:5000` · Swagger at `http://localhost:5000/swagger`
-
-### Frontend
-
-```bash
-cd frontend
-npm install
-ng serve
-```
-
-Frontend runs at `http://localhost:4200`
-
-### Docker (dev stack)
-
-```bash
-docker-compose -f docker-compose.dev.yml up
-```
-
----
-
-## Configuration
-
-`backend/appsettings.json` — override in `appsettings.Development.json` or environment variables:
-
-| Key | Default | Description |
-|---|---|---|
-| `ConnectionStrings:ExtrudexDb` | `Host=localhost;...` | PostgreSQL connection string |
-| `FilamentUsageSync:PollingInterval` | `00:05:00` | Sync job interval |
-| `FilamentUsageSync:RequestTimeout` | `00:00:30` | Moonraker request timeout |
-| `FilamentUsageSync:Enabled` | `true` | Enable/disable background sync |
-
----
-
-## Real-Time Events
-
-SignalR hub endpoint: `/hubs/printer`
-
-Clients receive `PrinterHub` events for live printer status, job progress, and spool consumption updates.
-
----
-
-## API Overview
-
-| Route prefix | Resource |
-|---|---|
-| `/api/filaments` | Filament catalog |
-| `/api/spools` | Spool inventory |
-| `/api/printers` | Printer registry |
-| `/api/print-jobs` | Print job tracking |
-| `/api/material-bases` | Material base types |
-| `/api/material-finishes` | Material finishes |
-| `/api/material-modifiers` | Material modifiers |
-| `/api/material-lookups` | Combined material lookup |
-| `/api/cost-analysis` | Cost-per-print and COGS |
-| `/api/qr` | QR code generation |
-
-Full schema available at `/swagger` when running in dev.
-
----
-
-## CI
-
-Gitea Actions pipeline (`.gitea/workflows/dev.yml`) runs on every push to `dev`:
-
-- `dotnet build`
-- Frontend `ng build`
-
----
-
-## Branch & PR Rules
-
-- All feature branches target `dev` — **never `main`**
-- Branch naming: `agent/<agent>/CUB-N-short-description`
-- PR titles: `CUB-N: short description`
-- PRs require Otto review before Joshua merges
