- Add EdgeTTSAdapter to bin/deepdive_tts.py (provider key: "edge-tts") default voice: en-US-GuyNeural, no API key required - Add EdgeTTS class to intelligence/deepdive/tts_engine.py - Update HybridTTS to try edge-tts as fallback between piper and elevenlabs - Add --voice-memo flag to bin/night_watch.py for spoken nightly reports - Add edge-tts>=6.1.9 to requirements.txt - Create docs/voice-output.md documenting all providers and fallback chain - Add tests/test_edge_tts.py with 17 unit tests (all mocked, no network) Fixes #1126 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Deep Dive: Automated Intelligence Briefing System
Sovereign, automated daily intelligence pipeline for the Timmy Foundation fleet.
Vision
Zero-manual-input daily AI-generated podcast briefing covering:
- arXiv (cs.AI, cs.CL, cs.LG)
- OpenAI, Anthropic, DeepMind research blogs
- AI newsletters (Import AI, TLDR AI)

Status: IMPLEMENTATION COMPLETE
This is no longer a reference scaffold — it is a production-ready executable pipeline.
| Component | Status | File |
|---|---|---|
| Phase 1: Aggregation | ✅ Complete | pipeline.py — RSS fetcher with caching |
| Phase 2: Relevance | ✅ Complete | pipeline.py — sentence-transformers ranking |
| Phase 3: Synthesis | ✅ Complete | pipeline.py — LLM briefing generation |
| Phase 4: Audio | ✅ Complete | tts_engine.py — Piper + ElevenLabs hybrid |
| Phase 5: Delivery | ✅ Complete | pipeline.py — Telegram text + voice |
| Orchestrator | ✅ Complete | pipeline.py — asyncio CLI + Python API |
| Tests | ✅ Complete | tests/test_e2e.py — dry-run validation |
| Systemd Timer | ✅ Complete | systemd/deepdive.timer — 06:00 daily |
Quick Start
See QUICKSTART.md for exact commands to run the pipeline.
Sovereignty Compliance
| Component | Implementation | Non-Negotiable |
|---|---|---|
| Aggregation | Local RSS polling | No third-party APIs |
| Relevance | sentence-transformers local | No cloud embeddings |
| Synthesis | Gemma 4 via Hermes llama-server | No OpenAI/Anthropic API |
| TTS | Piper TTS local | No ElevenLabs |
| Delivery | Hermes Telegram gateway | Existing infra |
