Introducing TVN Bridge: AI That Can’t Disobey Your Rules

AI coding assistants are powerful. Claude Code can refactor entire modules. Cursor can generate complex features. Aider can commit directly to your repo. But with that power comes a problem nobody talks about enough:

Who’s actually in control?

Today we’re introducing TVN Bridge — a local-first AI governance platform that puts you back in the driver’s seat. Not by limiting what AI can do, but by enforcing how it does it.

The Problem

If you’ve used an AI coding assistant, you’ve probably experienced one of these:

  1. The accidental leak. You paste your project into ChatGPT and realize too late that .env was included. Your API keys are now on someone else’s server.

  2. The destructive command. An AI agent runs git push --force or rm -rf on a directory you didn’t intend. Your work is gone.

  3. The context amnesia. You explain your architecture rules for the fifth time this week. The AI forgets everything between sessions.

  4. The token burn. Your AI reads 40 files when it only needed 3. You’re paying for wasted context.

These aren’t edge cases. They’re the daily reality of AI-assisted development in 2026. And the current solutions — “just be careful,” “add it to the system prompt,” “trust the model’s alignment” — aren’t good enough.

Our Philosophy: Controllable Amplification

TVN Bridge is built on a simple principle: humans remain the authority, AI amplifies under enforced constraints.

We call this controllable amplification. It’s the opposite of “give the AI full access and hope for the best.” Instead, we built environmental controls that operate at the system level — below the model, outside its context window, impossible for it to reason around.

The AI doesn’t follow your rules because you asked nicely. It follows them because the execution environment won’t let it do otherwise.

What TVN Bridge Does

The Sovereign Governance Firewall

Every tool call an AI agent makes passes through our firewall first. Before Claude Code can write a file, before it can run a bash command, before it can push to git — the firewall intercepts and makes a decision.

Three security tiers:

  • Standard — Blocks all write operations (30+ destructive patterns). The AI can read freely but must use governed tools to modify anything.
  • Strict — Standard protections plus blocks reads of sensitive files (.env, SSH keys, credentials).
  • Paranoid — Whitelist-only. Nothing runs unless explicitly permitted.

The overhead? Less than 10 milliseconds per decision. You won’t notice it’s there — until it saves you.

This is OWASP LLM06 (Excessive Agency) compliance built into your development workflow, not bolted on as an afterthought.

The Context Gate

Here’s something we discovered during development: when AI agents have unrestricted file access, they read everything. Grep the whole project. Cat entire directories. Burn through your token budget reading files that aren’t relevant.

The Context Gate changes that. It blocks direct file exploration (Read, Glob, Grep) until the agent uses TVN’s semantic search first. The agent has to look at the map before it can explore the territory.

The result? 90-97% token savings compared to grep-and-cat workflows. In case studies, agents using the Context Gate needed 83% fewer tool calls and produced more accurate results — because they were reading the right files, not all files.

This mechanism has no known prior art.

Truth Nodes

Every project has rules that should never be violated. “Core logic never imports from the CLI layer.” “All API responses include a timestamp.” “The database schema requires migration scripts.”

Truth Nodes are human-defined invariants that get injected into every AI context pack, every time. They sit at the top of the context — positional priority that ensures the AI reads them before anything else.

The AI can’t modify Truth Nodes. It can’t delete them. It can’t “decide” they don’t apply. They are your project’s constitution.

Memory Nodes

Decisions, priorities, focus areas — the high-level context that AI assistants forget between sessions. Memory Nodes persist across conversations and get injected automatically.

“Current focus: refactoring the auth module.” “Decision: using PostgreSQL, not SQLite.” “Bug found: race condition in session handler — do not touch until resolved.”

Your AI reads these on startup. No more repeating yourself.

Zero Trust File Editing

When an AI does need to modify a file, TVN enforces a three-step protocol:

  1. HALT — The system blocks the edit and generates a one-time confirmation token.
  2. Handshake — The human reviews the proposed change and provides the token.
  3. Execute — The edit proceeds, logged to the audit trail.

For trusted sessions, you can issue a SUDO token — time-limited (1 to 480 minutes), cryptographically random, file-based. The AI can operate autonomously within the session window, and the token expires automatically.

Universal Audit Trail

Every decision the firewall makes — every ALLOW, every BLOCK — is logged with a timestamp, the tool name, the rule that triggered, and the source (CLI, dashboard, MCP, or hook). Cross-platform file locking ensures nothing is lost, even during parallel operations.

Export as JSON or CSV. Know exactly what your AI did, when, and why.

Local-First. Always.

TVN Bridge runs entirely on your machine. No cloud. No telemetry. No phone-home.

Your code stays in your .tvn/ directory. Your secrets stay unindexed (automatic .gitignore + .tvnignore + 52 default ignore patterns). Your audit logs stay on your disk.

We don’t see your code. We don’t want to. That’s the point.

What’s Included

TVN Bridge v0.10.9 Beta ships with:

  • Sovereign Governance Firewall with 3 security tiers
  • Context Gate for 90-97% token savings
  • Smart Core — semantic search across 27 file types with line-level results
  • Truth Nodes and Memory Nodes for persistent project context
  • Executive Dashboard — 11-page SvelteKit web UI
  • Launch Pad — 18 presets for governed AI tool launching (Claude Code, Aider, Ollama, and more)
  • MCP Integration — 16 tools for Claude Code and Claude Desktop
  • Desktop App — Qt application with embedded governed terminals
  • Zero Trust file editing with SUDO tokens
  • Universal Audit Trail with JSON/CSV export
  • Agent Sessions for pre-authorized autonomous operation
  • 459 passing tests

Who It’s For

If you use AI coding assistants and care about any of the following, TVN Bridge is for you:

  • Privacy — You handle proprietary code, client data, or secrets
  • Control — You want governance that can’t be prompt-engineered away
  • Efficiency — You’re tired of burning tokens on irrelevant context
  • Accountability — You need audit trails for compliance or peace of mind
  • Consistency — You want architecture rules enforced, not suggested

What’s Next

TVN Bridge is in active beta. We’re working toward v1.0 with refinements to proprietary features across 5 embodiments and 18 intellectual property claims.

If you’re interested in early access, join the waitlist. We’re building the future of AI-assisted development — one where humans stay in control.

Your code. Your rules. Your machine.
