helix-ttd-gemini 1.4.4

Constitutional AI governance utilities for the Helix-TTD Federation

🛡️ Constitutional Guardian (Helix-TTD)

[FACT] Real-time AI governance for the Gemini Live API. [HYPOTHESIS] Intercepting voice and text drift at the edge prevents misaligned AI behavior from reaching the user.

This project is a submission for the Gemini Live Agent Challenge (March 2026).

Current Release: v1.4.4

🚀 Key Features

• 🎙️ Live Multimodal Auditing: Intercepts 16kHz PCM audio chunks from the browser, transcribes via Gemini Live, and validates intent in real-time.
• 🧠 Reasoning Engine (Gemini 3.1 Pro Preview): Utilizes state-of-the-art reasoning capabilities. Model default: gemini-3.1-pro-preview for Live Audio and Text paths.
• 🛡️ Constitutional Invariants: Enforces the "Four Immutable Invariants" (Epistemic, Agency, Guidance, Prediction).
• 📊 Real-time Dashboard: High-fidelity Chart.js dashboard showing latency, drift counts, and audit logs with visual "Intervention" flashes.
• ⚓ Cryptographic Receipts: Generates non-repudiable receipts for every valid AI response, ready for Bitcoin L1 notarization.
• 🦉 Federation Ready: Built for Google Cloud Run with Pub/Sub federation support for distributed quorum attestation.

📈 Engineering Standards

• 100% Test Pass Rate: 168/168 tests passing.
• High Coverage: 75% statement coverage across all critical modules.
• Linting: 100% compliant with ruff, black, and isort.

📦 Installation

From PyPI (Recommended)

pip install helix-ttd-gemini

From Source

git clone https://github.com/helixprojectai-code/helix-ttd-gemini-cli.git
cd helix-ttd-gemini-cli
pip install -e .

🛠️ Getting Started

Local Development

1. Install Dependencies:

   pip install -r helix_code/requirements.txt
   

2. Set API Key + Model Defaults:

   $env:GEMINI_API_KEY = "your-api-key"
   $env:GEMINI_LIVE_MODEL = "gemini-2.5-flash-native-audio-preview-12-2025"
   $env:GEMINI_TEXT_MODEL = "gemini-3.1-pro-preview"
   

3. Start the Guardian:

   $env:PYTHONPATH = "helix_code"
   python helix_code/live_guardian.py
   

4. Open the Demo: Navigate to http://localhost:8180/ in your browser.

🎙️ Live Multimodal Auditing

Real-time audio transcription with constitutional validation:

# Start the demo server
python helix_code/live_demo_server.py

# Open the audio audit client
# http://localhost:8000/audio-audit

Features:

• 16kHz PCM mono audio capture from browser
• Real-time streaming to Gemini Live API (gemini-2.5-flash-native-audio-preview-12-2025 default)
• Instant transcription with constitutional validation
• Visual intervention alerts for drift detection
• Optional auth hardening: AUDIO_AUDIT_TOKEN and AUDIO_AUDIT_ALLOWED_ORIGINS
• Abuse controls: HELIX_MAX_AUDIO_CHUNK_BYTES, HELIX_MAX_AUDIO_B64_CHARS, HELIX_AUDIO_RATE_WINDOW_SECONDS, HELIX_AUDIO_MAX_CHUNKS_PER_WINDOW
• Runtime verification endpoint: GET /api/runtime-config

How to Use:

1. Click "Connect" to establish WebSocket connection
2. Click 🎤 and allow microphone access
3. Speak naturally - audio streams in real-time
4. Watch transcriptions appear with validation badges
5. Constitutional violations trigger red "DRIFT" alerts

Cloud Deployment

The project is optimized for Google Cloud Run.

gcloud run deploy constitutional-guardian --source . --region us-central1 --allow-unauthenticated --port 8180

# Verify effective runtime model/auth/limits (non-secret)
curl http://localhost:8180/api/runtime-config

🎥 Recording Sprint (March 12th)

This codebase is currently in its Phase 6.1 (Pre-Filming) stable state. All visual triggers and simulation scenarios are tuned for high-impact demonstration.

🏛️ Constitutional Framework

The Guardian enforces four immutable invariants:

Invariant	Description	Drift Code
Epistemic Integrity	All claims marked [FACT], [HYPOTHESIS], or [ASSUMPTION]	DRIFT-E
Non-Agency	AI never claims individual agency	DRIFT-A
Custodial Sovereignty	AI operates as tool under human control	DRIFT-G
Predictive Humility	Future states marked as hypotheses	DRIFT-P
