+## 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`](QUICKSTART.md) for exact commands to run the pipeline.
