+
+## What is Proxyverse?
+
+A Manifest V3 browser extension (Chrome, Edge, Firefox) for proxy profile management with auto-switch rules and PAC script support. It is an alternative to Proxy SwitchyOmega.
+
+## Build and Test Commands
+
+```bash
+npm run build           # Type-check (vue-tsc) + build for Chrome/Edge
+npm run build:firefox   # Type-check + build for Firefox (transforms manifest)
+npm run build:test      # Build in test mode (no Sentry, no visualizer)
+npm run dev             # Vite dev server
+npm test                # Run vitest in watch mode
+npm run coverage        # Single run with coverage report
+npx vitest run tests/services/proxy/profile2config.test.ts  # Run a single test file
+```
+
+CI runs `npm run coverage` on PRs to main/develop; `npm run build` + `npm run build:firefox` on pushes and tags.
+
+## Architecture
+
+### Three build entry points
+
+The Vite config defines three entry points that produce the extension bundle:
+- **`index.html`** / **`popup.html`** -- Both load `src/main.ts` (Vue app). The Vue router uses hash history: `#/popup` renders `PopupPage`, `#/` renders `ConfigPage` with nested profile/preference routes.
+- **`src/background.ts`** -- Service worker. Wires up proxy auth, request stats, and badge indicator. No Vue, no DOM.
+
+### Browser adapter layer (`src/adapters/`)
+
+`BaseAdapter` defines the abstract contract for all browser APIs (storage, proxy, webRequest, tabs, i18n). Concrete implementations: `Chrome`, `Firefox`, `WebBrowser` (dev stub). A singleton `Host` is auto-detected at import time and used everywhere. This is the only layer that touches `chrome.*` or `browser.*` APIs directly.
+
+### Proxy engine (`src/services/proxy/`)
+
+The core complexity lives here:
+- **`profile2config.ts`** -- `ProfileConverter` turns a `ProxyProfile` into a `ProxyConfig` (for `chrome.proxy.settings`). For non-PAC profiles and auto-switch profiles, it **generates PAC scripts via AST** using `escodegen`/`acorn` node builders in `scriptHelper.ts`. Auto-switch profiles compose multiple sub-profiles by generating `register()` calls that build a lookup table.
+- **`pacSimulator.ts`** -- JS reimplementations of PAC functions (`shExpMatch`, `isInNet`) used to simulate PAC evaluation in-extension (e.g., for tab badge resolution). `isInNet` returns `UNKNOWN` when given a hostname instead of an IP (can't do DNS in extension context).
+- **`auth.ts`** -- Resolves proxy auth credentials by walking the profile tree (auto-switch profiles delegate to sub-profiles).
+
+### Profile system (`src/services/profile.ts`)
+
+Profiles are stored in `chrome.storage.local` under key `"profiles"`. Types: `ProfileSimple` (proxy/pac), `ProfilePreset` (system/direct), `ProfileAutoSwitch` (rule-based routing). System profiles `DIRECT` and `SYSTEM` have fixed IDs `"direct"` and `"system"`.
+
+### Config import/export (`src/services/config/schema/`)
+
+Schema definitions for importing/exporting profile configurations using `io-ts` for runtime type validation.
+
+## Critical Gotcha: `deepClone()` must use JSON round-trip
+
+`deepClone()` in `src/services/utils.ts` uses `JSON.parse(JSON.stringify(obj))`. **Do not replace with `structuredClone()`** -- Vue's reactive Proxy objects throw `DataCloneError` under `structuredClone()`. The JSON round-trip serializes through Vue's Proxy traps and produces plain objects safe for `chrome.storage`.
+
+## Firefox build differences
+
+The `vite.config.ts` `TRANSFORMER_CONFIG` rewrites `manifest.json` at build time for Firefox:
+- Replaces `background.service_worker` with `background.scripts` array
+- Removes `version_name`
+- Adds `browser_specific_settings.gecko`
+
+## Path alias
+
+`@/` maps to `src/` (configured in both `vite.config.ts` and `tsconfig.json`).
+
+## i18n
+
+Translation strings live in `public/_locales/{locale}/messages.json`. Translations are managed via Transifex.
