+# Overview
+
+## Goal & Scope
+- **Goal**: Produce a reproducible, flash‑able Armbian image for the BDY‑G18‑Pro RK3568 router (8 GB DDR4, 256 GB eMMC, 32 MB SPI‑NOR, RTL8367S‑5‑port DSA switch).  
+- **Target OS**: Community “DIY” Armbian 13.3 (Debian 13.3 Trixie) base, upgraded to kernel 6.18.x (current builds use 6.18.39 → 6.18.40).  
+- **Preferred Image**: *stock* image – uses vendor‑verified boot chain (U‑Boot SPL/U‑Boot on SPI‑NOR) plus a minimal Armbian rootfs. A *self‑built* mode is also available for auditability.
+- **Host / Language**: Documentation Chinese; primary development host Windows (PowerShell) with cross‑platform Bash support.
+- **Design Philosophy**: KISS & YAGNI; reuse existing framework; shallow Git clones; pinned `RKBIN_GIT_COMMIT=ce50c0d1`; line‑ending LF enforced via `.gitattributes`.
+
+## Repository Layout
+| Directory | Inclusion | Exclusion |
+|-----------|-----------|-----------|
+| `arm64‑custom/` | Tracked | – |
+| `evidence/` | Tracked | – |
+| `aidocs/` | Tracked | – |
+| `backups/`, `outputs/`, `work/`, `tools/`, large binaries, Docker cache, tool logs | Ignored | – |
+| `outputs/armbian-g18pro/` | Final artefacts (compressed image, SHA‑256, verification report, build log) | – |
+| `armbian‑g18pro‑cache` (Docker volume) | Persistent cache (~19 GB) | – |
+
+## Build Infrastructure
+- **Docker image**: `ghcr.io/armbian/docker-armbian-build:armbian-ubuntu-noble-latest`.
+- **Cache volume**: `armbian‑g18pro‑cache` (~19 GB) holds U‑Boot, kernel, rootfs, ccache.
+- **Orchestrator**: Python script `armbian‑custom/build_g18pro.py` + PowerShell wrapper `build_g18pro.ps1`; works on Windows PowerShell **or** Linux Bash.
+- **Environment checks**: Require `git` and `docker`; verify required files (`bdy‑g18‑pro.csc`, DTB, boot‑region asset). Abort if < 8 GiB free space.
+- **Proxy handling**: Optional env var `G18PRO_PROXY`; stripped inside Docker; per‑tool `.curlrc`, `.wgetrc`, git `insteadOf` rewrites.
+- **Shallow clones**: `git clone --depth 1` for Armbian source and kernel (≈ 313 MiB). Reduces download from > 2 GiB.
+- **Loop‑device shim**: Bind‑mount `/dev` read‑only to `/tmp/dev` inside container; required for partition stage on Docker Desktop (Windows).
+- **Image creation**: `xz`‑compression, SHA‑256 recorded in a JSON manifest and verified after each build.
+
+## Hardware Architecture
+| Item | Specification |
+|------|----------------|
+| **SoC** | Rockchip RK3568 – 4× Cortex‑A55 @ 2 GHz, Mali‑G710, VPU, RGA, HDMI |
+| **Memory** | 8 GB DDR4 HS200 (2.5 V) |
+| **Storage** | 256 GB eMMC (boot + rootfs) + 32 MB Winbond W25Q256JW SPI‑NOR (blank) |
+| **Switch** | Realtek RTL8367S 5‑port DSA (GMAC1 active, GMAC0 disabled) |
+| **UART2 console** | `serial@fe660000` → `ttyS2` at 1 500 000 baud, 3.3 V (pins: RX = GPIO0_D0, TX = GPIO0_D1). |
+
+## Key Preferences (Scenario‑Level)
+- Language: Chinese.
+- Host: Windows (PowerShell) – scripts also work on Linux Bash.
+- Design: KISS & YAGNI, shallow clones, pinned blobs, LF line endings, Docker cache volume retained.
+- Secrets: Vaultwarden only (repo stores entry names, not values).
+- AI / Git integration: Disabled by default.
+- Network: TCP congestion **Cubic**, TSO disabled.
+- Git: Shallow clones, `core.autocrlf=false`, `.gitattributes` enforces LF.
+- Docker: Cache volume `armbian‑g18pro‑cache`, proxy stripped, optional `G18PRO_PROXY`.
