+## Decision: Native Windows over WSL2 (2026-04-25)
+
+User asked whether to use WSL Ubuntu 24.04 or native Windows. **Native Windows chosen.** Reasons:
+
+1. **Global hotkey** — WSL Electron cannot register a Windows OS-level shortcut. `Ctrl+Shift+J` from real Windows apps (Chrome, Slack, Excel) won't reach WSL Electron. Spec §1.1 core feature broken; "3-second friction" hypothesis (Spec §0 hypothesis 1) untestable.
+2. **OS native notifications** — WSLg cannot bridge libnotify to Windows action center. Strategy §4.1 immediate-reward toast invisible when user is in another app.
+3. **Clipboard image paste** — WSLg image clipboard is unreliable. In-scope screenshot flow (Spec §1.1) breaks.
+4. **Tray icon** — WSLg has no system tray API. Tray menu, close-to-hide, "구출한 메모 보기" entry path (Spec §5.5) gone.
+5. **Data path** — `\\wsl$\...` instead of `%APPDATA%\Inkling\`. User can't browse data via Explorer.
+6. **Performance numbers** — "hotkey → window p95 < 100ms" measurement skewed by WSLg compositor.
+
+Dev-DX cost (less Linux-shell familiarity) is single-session pain. Dogfood-hypothesis cost (WSL silently breaks the slice) is fatal.
+
+**Hybrid recommendation:** core dev (npm/Electron) on Windows native; WSL allowed only as auxiliary for Linux utilities (`grep`/`find`/`jq`) when convenient.
+
+### Pre-flight checklist for the Windows machine
+
+1. Node 24.15.0 LTS via **nvm-windows** or **Volta**
+2. **Visual Studio Build Tools 2022** + workload "Desktop development with C++" (required for `better-sqlite3` native compile)
+3. **Ollama on a LAN server** (not on the Windows machine). User-defined IP, e.g. `http://192.168.x.y:11434`. Pre-pull `gemma4:9b` on that server. Confirm reachable from Windows: `curl http://<lan-ip>:11434/api/tags` should list `gemma4:9b`.
+4. **Git for Windows**
+5. Editor (VS Code, Cursor, etc.)
+6. **Claude Code for Windows**
+
+### Implication for slice plan/spec (LAN Ollama)
+
+The slice plan currently wires `new LocalOllamaProvider()` with no args (defaults to `http://localhost:11434`) in **Plan Task 30 main entry**. Since the dogfood machine reaches Ollama over LAN, that one line needs adjustment. Two minimal-change paths:
+
+- **Env var (recommended):** change the Task 30 instantiation to
+  ```ts
+  const provider = new LocalOllamaProvider({
+    endpoint: process.env.INKLING_OLLAMA_ENDPOINT
+  });
+  ```
+  `undefined` falls back to localhost (preserves Linux/local-Ollama dev). Set `INKLING_OLLAMA_ENDPOINT=http://192.168.x.y:11434` in Windows env (User-level Environment Variables) before running `npm run dev`.
+- **Hardcode for dogfood:** pass the LAN URL directly during dogfood; revert before any commit. Simplest but not committable.
+
+Spec §1.2 lists "LAN Ollama Provider" as deferred, but that meant a separate `LanOllamaProvider` *class*. `LocalOllamaProvider` already accepts a custom `endpoint`, so this is configuration, not new code. The Provider abstraction (Spec §2.2) was designed for exactly this.
+
+The new session should ask the user whether to fold the env-var change into Task 30 (preferred) or treat it as a one-off dogfood hardcode.
+
+Health-check expectations under LAN:
+- LAN unreachable (server off, wrong IP, firewall) → OllamaBanner shows "Inkling 정리가 잠시 멈췄습니다. Ollama를 실행해주세요." Capture continues normally; pending notes accumulate. Spec §6.1 row 4 behavior unchanged.
+- 120s generate timeout (Plan Task 12) is generous enough to absorb LAN latency on slow GPUs. No tuning needed initially.
