+# ⛔ ABSOLUTE GIT RULE — READ FIRST (2026-06-11)
+
+**NEVER run any git command that modifies git history OR the working tree, in ANY repo** (wayfern, wayfern-macos, wayfern-test, donutbrowser, build/src), **unless the user EXPLICITLY authorizes that exact command.** Forbidden without per-command authorization: `commit`, `revert`, `cherry-pick`, `restore`, `checkout` (files/branches), `reset`, `rebase`, `merge`, `stash`, `clean`, `apply`, `add`, `rm`, `push`, any force op. Only read-only git (`status`, `log`, `show`, `diff`, `ls-files`, `rev-parse`) is allowed without asking. **Authorization is per-command: 1 explicit authorization = exactly 1 command.** If a git mutation seems needed, STOP and ask for that one command.

 Three log surfaces, in order of usefulness:

- **Donut Browser GUI** — `~/Library/Logs/com.donutbrowser/DonutBrowser.log` on macOS (newest = active session; older `DonutBrowser_<date>.log` are rotated). The GUI / Tauri / `browser_runner` / `proxy_manager` / `sync` all log here. Search for `Camoufox`, `Wayfern`, `Starting local proxy`, `Configured local proxy` to find a launch chain. Dev builds write to `DonutBrowserDev.log` instead.

Dev builds write to `DonutBrowserDev.log` instead.
 - **donut-proxy worker** — `$TMPDIR/donut-proxy-<config_id>.log`. One file per proxy worker process (each profile launch spawns a fresh one). Map a worker to its launch via the `Cleanup: browser PID X is dead, stopping proxy worker <id>` lines in DonutBrowser.log, or by mtime. CONNECT requests, upstream accept/reject (status lines like `HTTP/1.1 402 user reached limit`), and tunnel errors are at INFO/WARN — anything finer is at TRACE and requires `RUST_LOG=donut_proxy=trace`. The `Upstream CONNECT response coalesced N byte(s) of payload — these would be dropped without forwarding` warning marks a real bug in `handle_connect_from_buffer` if it ever fires.
- **Camoufox stderr** — `$TMPDIR/camoufox-stderr-<profile_id>.log`, written by `camoufox_manager::launch_camoufox`. Captures NSS / GPU Helper / juggler errors. Firefox does **not** print TLS/network errors here by default — set `MOZ_LOG=nsHttp:5,signaling:5` on the env if you need that. The `RustSearch.sys.mjs missing field 'recordType'` lines are noise from our `search.json.mozlz4` schema being slightly off for FF150+; not a network problem.

 Linux/Windows swap `~/Library/Logs/com.donutbrowser/` for the platform-appropriate location (see `app_dirs::app_name()`), but the `$TMPDIR` worker logs are always under the system temp dir.

 ## Features

 - **Unlimited browser profiles** — each fully isolated with its own fingerprint, cookies, extensions, and data
- **Chromium & Firefox engines** — Chromium powered by [Wayfern](https://wayfern.com), Firefox powered by [Camoufox](https://camoufox.com), both with advanced fingerprint spoofing
+- **Anti-detect Chromium engine** — powered by [Wayfern](https://wayfern.com), which is privacy-focused Chromium fork that comes with advanced fingerprint spoofing which naturally hides information in a way that is not detected by Cloudflare, reCaptcha v3, and other browser fingerprinting and anti-bot services.
 - **DNS AdBlocker** - block ads, trackers, and other unwanted content with per-profile DNS blocking
 - **Proxy support** — HTTP, HTTPS, SOCKS4, SOCKS5 per profile, with dynamic proxy URLs
 - **VPN support** — WireGuard configs per profile
