+          # PROJECT SCOPE
+
+          - **Donut Browser** — this repo. A Tauri desktop launcher (Rust + Next.js) that
+            downloads, manages, and launches anti-detect browser profiles. In-scope for bug
+            reports about profile management, downloads, sync, proxy, VPN, the launcher UI,
+            its API, MCP server, and the bundled `donut-sync` self-hosted server.
+          - **Wayfern** — a Chromium fork maintained by zhom (the same maintainer). Wayfern
+            bugs are in-scope here unless they are obviously upstream Chromium issues.
+          - **Camoufox** — a Firefox fork by daijro. The maintainer of THIS repo does NOT
+            contribute to Camoufox and CANNOT fix bugs in it.
+              - Bugs about Camoufox's *internal* behavior (page rendering, JS engine,
+                dropdowns, form widgets, fingerprinting *as Camoufox implements it*,
+                checkbox/radio quirks) are UPSTREAM ONLY. Redirect to
+                https://github.com/daijro/camoufox/issues.
+              - Bugs about how Donut *launches, configures, or downloads* Camoufox are
+                in-scope here.
+          - **Forks of Wayfern or Camoufox** (e.g. CloverLabsAI, VulpineOS) are NOT
+            supported. Feature requests asking for them are out of scope.
+
+          # PAID vs FREE FEATURES
+
+          Source: donutbrowser.com pricing tiers (verbatim from translations).
+
+          ## Free (no account required)
+          - Unlimited local profiles
+          - Chromium (Wayfern) and Firefox (Camoufox) browser engines
+          - Proxy support (HTTP/SOCKS5)
+          - VPN support (WireGuard)
+          - Profile Management API & MCP (list / create / launch / kill / config)
+          - Cookie & Extension Management
+          - Set as default browser
+          - **Profile sync IS FREE if the user self-hosts the `donut-sync` server**
+
+          ## Pro ($16/mo) — adds:
+          - Browser Manipulation API & MCP (`type_text`, `click_element`,
+            `evaluate_javascript`, `screenshot`, `navigate`, etc.)
+          - Cross-OS fingerprinting (e.g. macOS user appearing as Windows)
+          - Profile Synchronizer for Wayfern
+          - 20 cloud profile backup (cloud sync via donutbrowser.com)
+          - Commercial use license
+
+          ## Team ($80/mo) — adds:
+          - 100 cloud profile sync
+          - Team collaboration, profile sharing, unlimited seats
+
+          # ANTI-PATTERNS
+
+          - **Regression**: user explicitly mentions a previous version that worked
+            differently ("worked in 0.21", "went from 2 to 8 false positives"). Do NOT
+            dismiss as "known issue" / "expected" / "false positive in Tauri apps". Ask
+            which exact version was the last working one and what changed.
+          - **Out-of-scope (upstream Camoufox)**: report is about Camoufox's own
+            behavior. Redirect, do not collect logs.
+          - **Fork-support request**: asks the maintainer to support an alternative
+            Wayfern/Camoufox fork. Acknowledge in one neutral sentence — do NOT call it
+            "clear", "reasonable", "well-thought-out", etc.
+          - **AI-generated / template-violating report**: report doesn't follow the
+            template, may cite "official documentation" via context7, deepwiki, or any
+            non-`donutbrowser.com` / non-`github.com/zhom` URL. The only authoritative
+            sources are this GitHub repo and donutbrowser.com.
+          - **Speculation about internals**: never write a "Possible cause" / "Likely
+            cause" / "Root cause" section. Never cite internal file paths or line
+            numbers. Never speculate about how subscription / paid-plan checks work.

+          # attach files directly, the active log is `DonutBrowser.log`; older
+          # rotated copies sit next to it (`DonutBrowser.log.YYYY-MM-DD-…`).

+
+          - **`CDP not ready after N attempts on port X: HTTP 5xx ...`** —
+            an HTTP 5xx (503 / 502) response from a freshly-launched
+            browser's `/json/version` endpoint always means *something on
+            the loopback path is intercepting the connection*: a firewall,
+            an antivirus web-shield (Kaspersky, Bitdefender, ESET, Avast /
+            AVG, Yandex Protect on Windows; Little Snitch, LuLu on macOS),
+            a VPN client that hijacks 127.0.0.1, or a corporate MDM /
+            proxy (Zscaler, Cisco AnyConnect, Netskope). Chrome's
+            DevTools endpoint never returns 5xx itself — only synthetic
+            responses from interception layers do. **Do NOT speculate
+            about Gatekeeper, first-launch verification, code signing, or
+            quarantine** — none of those cause a 5xx response, and
+            Gatekeeper never delays a launch long enough to surface as
+            "120 attempts". Lead with: which AV / web-shield / firewall /
+            VPN / MDM is installed, and ask the user to try with the AV's
+            web-shield component temporarily disabled (not the whole AV).

+          - NEVER include a `Possible cause` / `Likely cause` / `Root cause` / `Probably caused by` section. You do not have enough information; speculation is always wrong here.
+          - NEVER cite internal file paths or line numbers in the comment. Internal references rot and confuse non-developers.
+          - NEVER reference how subscription / paid-plan checks work internally. You do not know whether the user's claim is correct.
+          - NEVER call a report "well-documented", "well-structured", "clear", "thorough", "reasonable", "well-thought-out", or any similar evaluation. You are triage, not peer review.
+          - NEVER list more than one OS log path. Use ONLY the path matching the user's reported OS. If OS is unknown, ask for it instead of listing all three.
+          - NEVER validate a feature request as "a clear enhancement" / "a reasonable request" / similar. Acknowledge neutrally and ask only the missing info (use case, urgency).
+          - NEVER call a report "a known and expected behavior" or "a false positive" if the user mentions a regression. The triage tells you when this applies.
+
+          ## Classification handling
+          The triage classification (`triage.classification`) determines the response shape:
+
+          - `bug-in-scope`: ask for what is missing using the user's reported OS log path. Be concrete about how to obtain logs.
+          - `bug-upstream-camoufox`: redirect ONLY. One sentence acknowledging, then a sentence saying this is a Camoufox-internal issue and the maintainer of this repo does not contribute to Camoufox; ask the user to file at https://github.com/daijro/camoufox/issues. Do NOT ask for Donut logs. Stop after that.
+          - `bug-template-violation` or `ai-generated-junk`: politely ask the user to refile using the bug-report template (the Operating System, Donut Browser version, Which browser, Steps to reproduce, Error logs sections). If they cited "documentation" from any non-`donutbrowser.com`/non-`github.com/zhom` URL (e.g. context7, deepwiki), gently note that those are AI-generated third-party summaries and the only authoritative sources are this repo and donutbrowser.com.
+          - `feature-request`: one neutral sentence acknowledging, then ask only what is genuinely needed (concrete use case, whether a workaround would suffice). Do NOT validate.
+          - `fork-request`: one neutral sentence acknowledging the request. Note that this would substantially increase support burden and the maintainer evaluates such requests on a case-by-case basis. Ask whether the alternative fork supports all platforms the user uses (macOS / Windows / Linux). No "clear enhancement" language.
+          - `regression`: do NOT call known/expected. Ask which exact previous version was the last working one, what changed in the user's environment between then and now, and the specific delta in symptoms.
+          - `question`: answer briefly if obvious from repo guidelines / pricing; otherwise ask for clarification.
+
+          ## Paid-feature awareness
+          If `triage.is_paid_feature` is true, factor the pricing tiers into your reply. For Pro-only features (browser manipulation API/MCP, cross-OS fingerprinting, Wayfern Profile Synchronizer, cloud sync), confirm the user is logged in with an active subscription before asking for logs. If the issue is about cloud sync, mention that self-hosting `donut-sync` makes sync free and is a viable alternative.
+
+          ## Language
+          If the issue body is not in English, write the comment in English (the maintainer reads English). The FIRST line must politely ask the user to communicate in English so the maintainer can help. Then continue with the normal triage response, in English.
+
+          ## OS-specific log paths
+          Recommend Settings → Advanced → Copy logs first — it bundles the
+          latest rotated log onto the clipboard without the user hunting for
+          a directory. If they want to attach files directly, point at the
+          path that matches `triage.operating_system`. The active log is
+          always `DonutBrowser.log`; rotated copies sit next to it.
+            - macos:   `~/Library/Logs/com.donutbrowser/DonutBrowser.log`
+            - linux:   `~/.local/share/com.donutbrowser/logs/DonutBrowser.log`
+            - windows: `%LOCALAPPDATA%\com.donutbrowser\logs\DonutBrowser.log` (PowerShell: `Get-Content $env:LOCALAPPDATA\com.donutbrowser\logs\DonutBrowser.log -Tail 200`)
+            - unknown: ask the user to share their OS first.
+
+          ## Known error signatures (apply BEFORE asking generic questions)
+          If the issue body contains any of these, lead with the matching
+          response — do NOT speculate about other causes:
+
+          - `CDP not ready after N attempts on port X: HTTP 5xx ...` —
+            this is loopback interception by a firewall / antivirus
+            web-shield / VPN / MDM. Lead with that question (specifically:
+            Kaspersky, Bitdefender, ESET, Avast/AVG, Yandex Protect on
+            Windows; Little Snitch, LuLu, corporate MDM on macOS; any
+            VPN). Suggest temporarily disabling the AV's web-shield
+            component (NOT the whole AV) and retrying. Do NOT mention
+            Gatekeeper, first-launch verification, code signing, or
+            quarantine — none of those cause an HTTP 5xx response, and
+            Gatekeeper never delays a launch long enough to produce a
+            "120 attempts" failure.

 - Strings excluded from this rule: `console.log/warn/error`, dev-only debug labels, internal IDs, CSS class names, type names. If unsure whether a string renders to the user, assume it does and translate it.
 - **Never use `t(key, "fallback")` with a default-value second argument.** The 2-arg form is forbidden — every key must exist in every locale file before the call site lands. Fallbacks mask missing translations: a key missing from `ru.json` will silently render the English fallback to Russian users, so the bug never surfaces in CI or review. Only call `t("namespace.key")`. If a translation is missing for any locale, that's a bug to fix at the JSON, not a hole to paper over at the call site.
 - Empty-string values in non-English locales are also forbidden — a locale either has the right translation or it has the same content as English; never `""`. If a particular language doesn't need a particular phrase (e.g. a suffix that doesn't grammatically apply), refactor the JSX to use a single interpolated key (`t("foo.bar", { name })` with `"...{{name}}..."` in each locale) instead of splitting prefix/suffix.
+- When adding or removing keys across all seven locales, use a one-shot Python script in `/tmp/` that loads each `*.json`, mutates it, and writes it back. Seven sequential `Edit` calls drift (typos, ordering differences) and burn tokens; a single script keeps the locales in lockstep and is easy to throw away.
+
+## Backend error codes (mandatory)
+
+User-facing errors returned from a Tauri command MUST be JSON `{ "code": "FOO_BAR", "params": { … } }` strings — never raw English (`format!("Failed to …")`). The frontend resolves the code via `translateBackendError(t, err)` from `src/lib/backend-errors.ts`. Adding a new code requires four parallel edits:
+
+1. Emit the JSON from Rust:
+   ```rust
+   return Err(serde_json::json!({ "code": "FOO_BAR" }).to_string());
+   // or with params:
+   return Err(serde_json::json!({ "code": "FOO_BAR", "params": { "n": "5" } }).to_string());
+   ```
+2. Add `"FOO_BAR"` to the `BackendErrorCode` union in `src/lib/backend-errors.ts`.
+3. Add a `case "FOO_BAR":` in the switch that returns `t("backendErrors.fooBar", …)`.
+4. Add `backendErrors.fooBar` to all seven locale files.
+
+Raw error strings reach the user untranslated; that's the bug pattern this rule blocks.
+
+## Sub-page Dialog mode
+
+A `<Dialog>` becomes a first-class app sub-page (no modal overlay, no center positioning) when `subPage` is passed. Pages like Account, Settings, Proxy Management, and Extension Management use this. The pattern for a sub-page with tabs:
+
+```tsx
+<Dialog open={isOpen} onOpenChange={onClose} subPage={subPage}>
+  <DialogContent className="max-w-2xl flex flex-col">
+    <Tabs defaultValue="account">
+      <TabsList
+        className={cn(
+          "w-full",
+          subPage &&
+            "!bg-transparent !p-0 !h-auto !rounded-none justify-start gap-4",
+        )}
+      >
+        <TabsTrigger
+          value="account"
+          className={cn(
+            "flex-1",
+            subPage &&
+              "!flex-none !rounded-none !bg-transparent !shadow-none data-[state=active]:!bg-transparent data-[state=active]:!text-foreground data-[state=active]:!shadow-none text-muted-foreground hover:text-foreground !px-1 !py-1 text-xs",
+          )}
+        >
+          Account
+        </TabsTrigger>
+        …
+      </TabsList>
+      <TabsContent value="account" className="mt-4">…</TabsContent>
+    </Tabs>
+  </DialogContent>
+</Dialog>
+```
+
+Reference implementations: `src/components/account-page.tsx`, `src/components/proxy-management-dialog.tsx`. Reuse the exact class strings — the overrides are tuned to match the rest of the sub-page chrome.

+## App data directory naming
+
+`src-tauri/src/app_dirs.rs::app_name()` returns `"DonutBrowserDev"` when `cfg!(debug_assertions)` is true, `"DonutBrowser"` otherwise. So release builds (anything built via `tauri build` / `cargo build --release`) write to:
+
+- macOS — `~/Library/Application Support/DonutBrowser/`
+- Linux — `~/.local/share/DonutBrowser/`
+- Windows — `%LOCALAPPDATA%\DonutBrowser\`
+
+Debug builds (`cargo build`, `pnpm tauri dev`) write to the `DonutBrowserDev` sibling at the same root, and a `dev-{version}` `BUILD_VERSION` is injected via `build.rs`. Logs / screenshots referencing `DonutBrowserDev` therefore mean a local dev build is in play, not a release; useful when a bug report seems to disagree with what production users see.

+//! Camoufox ships two bundled preset files:

+//!   browsers running Firefox ≤148. The frozen "v135 line" — kept around
+//!   so users who haven't upgraded their Camoufox binary keep getting
+//!   consistent fingerprints.
+//! - `fingerprint-presets-v150.json` — the *newer* bundle, refreshed by
+//!   upstream as Camoufox tracks newer Firefox versions. This is the
+//!   bundle every newer Camoufox release uses; we make no assumption that
+//!   Firefox 150 is the ceiling.
+//!
+//! At launch we know the bundled Firefox version (see
+//! `config::get_firefox_version`) and pick `v135` or `newer` accordingly.
+//! The split point lives in `data::PRESETS_NEWER_MIN_FF` (currently 149)
+//! and is the only number we hard-code — anything ≥ that gets the newer

+//! Each on-disk file in `profiles/{uuid}/profile/` has:
+//! - **Filename**: `urlsafe_no_pad(HMAC-SHA256(profile_key, plaintext_relpath))[..32]`.
+//!   Deterministic so cross-machine sync sees stable filenames; same plaintext
+//!   path with same key always produces the same on-disk name.
+//! - **Content**: `nonce(12B) || AES-256-GCM(profile_key, path_len(2B-LE) || plaintext_path || file_bytes)`.
+//!   The plaintext relpath is encoded inside the ciphertext so a launch can
+//!   reconstruct the directory tree without a separate manifest.
+//!
+//! Wrong password fails the AES-GCM auth tag on the first decrypt, which
+//! doubles as password verification.
