# Canonical Index: Deep Dive Intelligence Briefing Artifacts

> **Issue**: [#830](http://143.198.27.163:3000/Timmy_Foundation/the-nexus/issues/830) — Deep Dive: Sovereign NotebookLM + Daily AI Intelligence Briefing  
> **Created**: 2026-04-05 by Ezra (burn mode)  
> **Purpose**: Single source of truth mapping every Deep Dive artifact in `the-nexus`. Eliminates confusion between implementation code, reference architecture, and legacy scaffolding.

## Status at a Glance

| Milestone | State | Evidence |
|-----------|-------|----------|
| Production pipeline | ✅ **Complete & Tested** | `intelligence/deepdive/pipeline.py` (26 KB) |
| Test suite | ✅ **Passing** | 9/9 tests pass (`pytest tests/`) |
| TTS engine | ✅ **Complete** | `intelligence/deepdive/tts_engine.py` |
| Telegram delivery | ✅ **Complete** | Integrated in `pipeline.py` |
| Systemd automation | ✅ **Complete** | `systemd/deepdive.service` + `.timer` |
| Fleet context grounding | ✅ **Complete** | `fleet_context.py` integrated into `pipeline.py` |
| Build automation | ✅ **Complete** | `Makefile` |
| Architecture docs | ✅ **Complete** | `intelligence/deepdive/architecture.md` |

**Verdict**: This is no longer a scaffold. It is an executable, tested system waiting for environment secrets and a scheduled run.

---

## Proof of Execution

Ezra executed the test suite on 2026-04-05 in a clean virtual environment:

```bash
cd intelligence/deepdive
python -m pytest tests/ -v
```

**Result**: `======================== 9 passed, 8 warnings in 21.32s ========================`

- `test_aggregator.py` — RSS fetch + cache logic ✅
- `test_relevance.py` — embedding similarity + ranking ✅
- `test_e2e.py` — full pipeline dry-run ✅

The code parses, imports execute, and the pipeline runs end-to-end without errors.

## Authoritative Path — `intelligence/deepdive/`

**This is the only directory that matters for production.** Everything else is legacy or documentation shadow.

| File | Purpose | Size | Status |

| `architecture.md` | Deep technical architecture for maintainers | 7,926 bytes | ✅ Current |
| `pipeline.py` | **Main orchestrator** — Phases 1-5 in one executable | 26,422 bytes | ✅ Production |
| `tts_engine.py` | TTS abstraction (Piper local + ElevenLabs API fallback) | 7,731 bytes | ✅ Production |
| `telegram_command.py` | Telegram `/deepdive` on-demand command handler | 4,330 bytes | ✅ Production |
| `fleet_context.py` | **Phase 0 fleet grounding** — live Gitea repo/issue/commit context | 7,100 bytes | ✅ Production |
| `config.yaml` | Runtime configuration (sources, model endpoints, delivery, fleet_context) | 2,800 bytes | ✅ Current |
| `requirements.txt` | Python dependencies | 453 bytes | ✅ Current |
| `Makefile` | Build automation: install, test, run-dry, run-live | 2,314 bytes | ✅ Current |
| `QUICKSTART.md` | Fast path for new developers | 2,186 bytes | ✅ Current |
| `PROOF_OF_EXECUTION.md` | Runtime proof logs | 2,551 bytes | ✅ Current |
| `systemd/deepdive.service` | systemd service unit | 666 bytes | ✅ Current |
| `systemd/deepdive.timer` | systemd timer for daily 06:00 runs | 245 bytes | ✅ Current |
| `tests/test_aggregator.py` | Unit tests for RSS aggregation | 2,142 bytes | ✅ Passing |
| `tests/test_relevance.py` | Unit tests for relevance engine | 2,977 bytes | ✅ Passing |
| `tests/test_e2e.py` | End-to-end dry-run test | 2,669 bytes | ✅ Passing |

### Quick Start for Next Operator

```bash
cd intelligence/deepdive

# 1. Install (creates venv, downloads 80MB embedding model)
make install

# 2. Verify tests
make test

# 3. Dry-run the full pipeline (no external delivery)
make run-dry

# 4. Configure secrets
cp config.yaml config.local.yaml
# Edit config.local.yaml: set TELEGRAM_BOT_TOKEN, LLM endpoint, TTS preferences

# 5. Live run
CONFIG=config.local.yaml make run-live

# 6. Enable daily cron
make install-systemd
```

## Legacy / Duplicate Paths (Do Not Edit — Reference Only)

The following contain **superseded or exploratory** code. They exist for historical continuity but are **not** the current source of truth.

| Path | Status | Note |
|------|--------|------|
| `bin/deepdive_*.py` (6 scripts) | 🔴 Legacy | Early decomposition of what became `pipeline.py`. Good for reading module boundaries, but `pipeline.py` is the unified implementation. |
| `docs/DEEPSDIVE_ARCHITECTURE.md` | 🔴 Superseded | Early stub; `intelligence/deepdive/architecture.md` is the maintained version. |
| `docs/DEEPSDIVE_EXECUTION.md` | 🔴 Superseded | Integrated into `intelligence/deepdive/QUICKSTART.md` + `README.md`. |
| `docs/DEEPSDIVE_QUICKSTART.md` | 🔴 Superseded | Use `intelligence/deepdive/QUICKSTART.md`. |
| `docs/deep-dive-architecture.md` | 🔴 Superseded | Longer narrative version; `intelligence/deepdive/architecture.md` is canonical. |
| `docs/deep-dive/TTS_INTEGRATION_PROOF.md` | 🟡 Reference | Good technical deep-dive on TTS choices. Keep for reference. |
| `docs/deep-dive/ARCHITECTURE.md` | 🔴 Superseded | Use `intelligence/deepdive/architecture.md`. |
| `scaffold/deepdive/` | 🔴 Legacy scaffold | Pre-implementation stubs. `pipeline.py` supersedes all of it. |
| `scaffold/deep-dive/` | 🔴 Legacy scaffold | Same as above, different naming convention. |
| `config/deepdive.env.example` | 🟡 Reference | Environment template. `intelligence/deepdive/config.yaml` is the runtime config. |
| `config/deepdive_keywords.yaml` | 🔴 Superseded | Keywords now live inside `config.yaml`. |
| `config/deepdive_sources.yaml` | 🔴 Superseded | Sources now live inside `config.yaml`. |
| `config/deepdive_requirements.txt` | 🔴 Superseded | Use `intelligence/deepdive/requirements.txt`. |

> **House Rule**: New Deep Dive work must branch from `intelligence/deepdive/`. If a legacy file needs to be revived, port it into the authoritative tree and update this index.

## What Remains to Close #830

The system is **built and tested**. What remains is **operational integration**:

| Task | Owner | Blocker |
|------|-------|---------|
| Provision LLM endpoint for synthesis | @gemini / infra | Local `llama-server` or API key |
| Install Piper voice model (or provision ElevenLabs key) | @gemini / infra | ~100MB download |
| Configure Telegram bot token + channel ID | @gemini | Secret management |
| Schedule first live run | @gemini | After secrets are in place |
| Alexander sign-off on briefing tone/length | @alexander | Requires 2-3 sample runs |

---

## Next Agent Checklist

If you are picking up #830 (assigned: @gemini):

1. [ ] Read `intelligence/deepdive/README.md`
2. [ ] Read `intelligence/deepdive/architecture.md`
3. [ ] Run `cd intelligence/deepdive && make install && make test` (verify 9 passing tests)
4. [ ] Run `make run-dry` to see a dry-run output
5. [ ] Configure `config.local.yaml` with real secrets
6. [ ] Run `CONFIG=config.local.yaml make run-live` and capture output
7. [ ] Post SITREP on #830 with proof-of-execution
8. [ ] Iterate on briefing tone based on Alexander feedback
