+# HPL Toolbox — Project Summary for AI
+
+## What this project is
+
+HPL Toolbox is an internal tool for a playable ad team. It ships as **two separate deliverables** from the same repo:
+
+1. **VS Code Extension** (`src/`) — a `.vsix` that adds tool panels as webview tabs inside VS Code.
+2. **Standalone Windows App** (`standalone/`) — a Go + WebView2 desktop app that exposes the same tools through a local HTTP server rendered in a native window. It is a **real, complete, production app** — not a prototype or subset.
+
+Both deliverables implement the same set of tools. New features are typically added to both.

+
+## Architecture notes
+
+### VS Code Extension
+- Each tool is a singleton webview panel (`singletonPanel` in `shared.ts`).
+- The panel HTML is returned as a template string from `getHtml()` inside each tool file.
+- Communication between extension host and webview uses `panel.webview.postMessage` / `onDidReceiveMessage`.
+- Settings are read from `vscode.workspace.getConfiguration('hplToolbox.*')` and contributed in `package.json`.
+- Session-persistent UI state (e.g. last selected server) uses `context.globalState`.
+
+### Standalone App
+- Go HTTP server on a random localhost port, served into a WebView2 window.
+- All pages return full HTML strings (no template files on disk).
+- Long-running operations (uploads, scans) use `newJSONStream` to stream NDJSON progress events — the browser reads these with `ReadableStream` and updates the UI incrementally.
+- Config is persisted to `%LOCALAPPDATA%\HPLToolbox\config.json` via `LoadConfig` / `SaveConfig`.
+- `localStorage` is used for lightweight UI-only state (e.g. last selected server in PLEC Upload).
+- Single-instance enforcement: on launch, tries to connect to a previous instance's port from a lock file and `POST /api/focus` to bring its window forward, then exits.
+
+### PLEC Upload — dual server detail
+- **Default (legacy)**: `POST http://167.99.227.249/src/upload_HTML_Experimental.php` with `fileUpload_N` / `iterationNameUpload_N` fields. Filenames are timestamped.
+- **Backup (WordPress)**: `POST http://20.255.60.183/wp-admin/admin-ajax.php` with `action=plec_upload_files`, `nonce`, `rows` (JSON array), and `file_N` fields. Login flow: POST `/wp-login.php` → GET `/file-upload/` to extract nonce. Iteration name is used as the uploaded filename. Preview URL is constructed as `/preview?theme=calcite&n1=<original>&m1=<saved>`.
+
+---
+
+## Build
+
+```powershell
+npm run build            # builds both .vsix and standalone .exe into dist/
+npm run build -- -Extension   # .vsix only
+npm run build -- -Standalone  # .exe only
+npm run run-standalone   # dev: go run . in standalone/
+npm run compile          # tsc only
+npm run watch            # tsc watch
+```
+
+Requires: Node.js, TypeScript (`npm install`), Go, optionally `vsce` and `rsrc`.
+
+---
+
+## Key config (VS Code settings)
+
+All under `hplToolbox.*`:
+
+| Key | Default | Purpose |
+|---|---|---|
+| `plec.uploadUrl` | `http://167.99.227.249/src/upload_HTML_Experimental.php` | Legacy server endpoint |
+| `plec.originUrl` | `http://167.99.227.249` | Origin/Referer for legacy uploads |
+| `plec.wpUsername` | `pm` | WordPress username for backup server |
+| `plec.wpPassword` | _(set)_ | WordPress password for backup server |
+| `applovin.cookie` | _(empty)_ | `__Host-APPLOVINID` cookie for p.applov.in |
+| `deviceSimulator.devicesUrl` | Google Drive link | Remote devices.json URL |
+| `deviceSimulator.languagesUrl` | Google Drive link | Remote languages.json URL |

+    - Device and language lists are fetched from a configurable Google Drive URL on open and cached for offline use, with built-in defaults as fallback.
+    - Device Simulator remote JSON URLs are configurable in VS Code extension settings (hplToolbox.deviceSimulator.devicesUrl / languagesUrl).
+    - Settings modal in standalone — accessible from any page via the ⚙ button, with Device Simulator and Initialize Project sections highlighted when opened from those tools.
+    - Device list is now sorted alphabetically in both extension and standalone.
+
+Changed
+    - Device Simulator settings gear now opens the VS Code extension settings (extension) or the global settings modal (standalone).

+    - Settings page in standalone replaced by a modal overlay available on every page.
+    - Initialize Project manifest URL is now configured via the settings modal instead of the inline settings panel.
+
+Fixed

+    - Added backup PLEC server (20.255.60.183) as a selectable upload target in PLEC Upload.

+    - Iteration name is used as the uploaded filename on the backup server.
+    - Selected server persists across sessions (VS Code globalState / localStorage in standalone).
+
+Changed
+    - Build scripts moved to scripts/ and added as npm run build and npm run run-standalone.
