What is BaleVPN CLAUDE.md?

A repository guide for BaleVPN, a project that reverse-engineers the Bale messenger web app and provides Rust and Android VPN clients and servers. It describes the shared networking components and supported modes.

Use it when changing BaleVPN, its Android app, its Rust transport, or the extracted Bale service definitions.

It gives coding agents the project context needed to work across the Rust, Android, VPN, and messaging-related code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.02648	$0.02648
Opus 5.5	$0.01059	$0.01059
Sonnet 5.5	$0.00530	$0.00530

Security

Grade B, and why

BaleVPN CLAUDE.md scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

What This Is

A reverse-engineering research project for the Bale messenger web app (web.bale.ai). It extracts protobuf service / message definitions from Bale's minified webpack bundles and ships:

bale-vpn-rust/ — a single Rust binary that runs as either VPN client (local SOCKS5 listener over a QUIC channel) or VPN server (TUN-based or userspace NAT bridging traffic from admitted Bale peers to the internet). HTTP management UI on 127.0.0.1:3001. CLI: bale-vpn [--port 3001] [--mode client|server] [--nat-mode kernel|userspace] [--headless].
bale-vpn-android/ — Android app that runs as either VPN client (device-wide TUN via VpnService, optional LAN-facing SOCKS5) or VPN server (userspace NAT, no root). Mode-toggle in the app's main screen.

Both apps consume the same Rust stack:

lktunnel-rust/ — WebRTC transport on webrtc-rs (pure Rust, no libwebrtc) + QUIC channel + userspace NAT. Reuses crates.io livekit-api (signal client) + livekit-protocol (wire types); no vendored crates, no patches.
lk-signaling-rust/ — generic signaling trait
bale-signaling-rust/ — Bale impl (WS client + RPCs + auth + contacts), single source of truth for the protocol

The Rust and Android server modes are interchangeable: an Android client can connect to either, same wire protocol.

Supported features

Role	Platform	Notes
Server	Rust (Linux)	Kernel TUN + iptables MASQUERADE — best throughput. One-time root setup. (Userspace NAT path also works.)
Server	Rust (macOS)	Kernel TUN (`utunN`) + pf anchor — best throughput. Runs as root.
Server	Rust (Windows)	Userspace NAT — no root, no driver install.
Server	Android	Userspace NAT — no root. APK install, no command line.
Client	Rust (any OS)	SOCKS5 listener on `127.0.0.1:1080` (configurable) over a QUIC channel.
Client	Android	Kernel TUN via `VpnService`. Optional LAN-facing SOCKS5 lets other devices on the same WiFi use this Android as their proxy.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

BaleVPN CLAUDE.md is an instructions file published in the GitHub repository kookoo1sabzy/BaleVPN (409 stars, last pushed 4mo ago), licensed MIT. It adds 2,648 tokens to every session, about $0.0106 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
