# Deep Dive — Operational Readiness Checklist

> **Issue**: [#830](https://forge.alexanderwhitestone.com/Timmy_Foundation/the-nexus/issues/830) — Deep Dive: Sovereign NotebookLM + Daily AI Intelligence Briefing  
> **Location**: `intelligence/deepdive/OPERATIONAL_READINESS.md`  
> **Created**: 2026-04-05 by Ezra, Archivist  
> **Purpose**: Bridge the gap between "code complete" and "daily briefing delivered." This is the pre-flight checklist for making the Deep Dive pipeline operational on the Hermes VPS.

## Executive Summary

The Deep Dive pipeline is **code-complete and tested** (9/9 tests pass). This document defines the exact steps to move it into **daily production**.

| Phase | Status | Blocker |
|-------|--------|---------|
| Code & tests | ✅ Complete | None |
| Documentation | ✅ Complete | None |
| Environment config | 🟡 **Needs verification** | Secrets, endpoints, Gitea URL |
| TTS engine | 🟡 **Needs install** | Piper model or ElevenLabs key |
| LLM endpoint | 🟡 **Needs running server** | `localhost:4000` or alternative |
| Systemd timer | 🟡 **Needs install** | `make install-systemd` |
| Live delivery | 🔴 **Not yet run** | Complete checklist below |

---

## Step 1: Environment Prerequisites

Run these checks on the host that will execute the pipeline (Hermes VPS):

```bash
# Python 3.11+
python3 --version

# Git
git --version

# Network outbound (arXiv, blogs, Telegram, Gitea)
curl -sI http://export.arxiv.org/api/query | head -1
curl -sI https://api.telegram.org | head -1
curl -sI https://forge.alexanderwhitestone.com | head -1
```

**All must return HTTP 200.**

---

## Step 2: Clone & Enter Repository

```bash
cd /root/wizards/the-nexus/intelligence/deepdive
```

If the repo is not present:
```bash
git clone https://forge.alexanderwhitestone.com/Timmy_Foundation/the-nexus.git /root/wizards/the-nexus
cd /root/wizards/the-nexus/intelligence/deepdive
```

---

## Step 3: Install Dependencies

```bash
make install
```

This creates `~/.venvs/deepdive/` and installs:
- `feedparser`, `httpx`, `pyyaml`
- `sentence-transformers` + `all-MiniLM-L6-v2` model (~80MB)

**Verify:**
```bash
~/.venvs/deepdive/bin/python -c "import feedparser, httpx, sentence_transformers; print('OK')"
```

---

## Step 4: Configure Secrets

Export these environment variables (add to `~/.bashrc` or a `.env` file loaded by systemd):

```bash
export GITEA_TOKEN="<your_gitea_api_token>"
export TELEGRAM_BOT_TOKEN="<your_telegram_bot_token>"
# Optional, for cloud TTS fallback:
export ELEVENLABS_API_KEY="<your_elevenlabs_key>"
export OPENAI_API_KEY="<your_openai_key>"
```

**Verify Gitea connectivity:**
```bash
curl -s -H "Authorization: token $GITEA_TOKEN" \
  https://forge.alexanderwhitestone.com/api/v1/user | jq -r '.login'
```

Must print a valid username (e.g., `ezra`).

**Verify Telegram bot:**
```bash
curl -s "https://api.telegram.org/bot${TELEGRAM_BOT_TOKEN}/getMe" | jq -r '.result.username'
```

Must print the bot username.

---

## Step 5: TTS Engine Setup

### Option A: Piper (sovereign, local)

```bash
# Install piper binary (example for Linux x86_64)
mkdir -p ~/.local/bin
curl -L -o ~/.local/bin/piper \
  https://github.com/rhasspy/piper/releases/download/v1.2.0/piper_linux_x86_64.tar.gz
tar -xzf ~/.local/bin/piper -C ~/.local/bin/
export PATH="$HOME/.local/bin:$PATH"

# Download voice model (~2GB)
python3 -c "
from tts_engine import PiperTTS
tts = PiperTTS('en_US-lessac-medium')
print('Piper ready')
"
```

### Option B: ElevenLabs (cloud, premium quality)

Ensure `ELEVENLABS_API_KEY` is exported. No local binary needed.

### Option C: OpenAI TTS (cloud, balance)

Update `config.yaml`:
```yaml
tts:
  engine: "openai"
  voice: "alloy"
```

Ensure `OPENAI_API_KEY` is exported.

---

## Step 6: LLM Endpoint Verification

The default config points to `http://localhost:4000/v1` (LiteLLM or local llama-server).

**Verify the endpoint is listening:**
```bash
curl http://localhost:4000/v1/models
```

If the endpoint is down, either:
1. Start it: `llama-server -m model.gguf --port 4000 -ngl 999 --jinja`
2. Or change `synthesis.llm_endpoint` in `config.yaml` to an alternative (e.g., OpenRouter, Kimi, Anthropic).

---

## Step 7: Dry-Run Verification

```bash
make run-dry
```

Expected output includes:
- `Phase 1: Source Aggregation` with >0 items fetched
- `Phase 2: Relevance Scoring` with >0 items ranked
- `Phase 0: Fleet Context Grounding` with 4 repos, commits, issues
- `Phase 3: Synthesis` with briefing saved to `~/.cache/deepdive/`
- `Phase 4: Audio disabled` (if TTS not configured) or audio path
- `Phase 5: DRY RUN - delivery skipped`

**If any phase errors, fix before proceeding.**

---

## Step 8: First Live Run

⚠️ **This will send a Telegram message to the configured channel.**

```bash
make run-live
# Type 'y' when prompted
```

Watch for:
- Telegram text summary delivery
- Telegram voice message delivery (if TTS + audio enabled)

---

## Step 9: Install Systemd Timer (Daily 06:00)

```bash
make install-systemd
```

**Verify:**
```bash
systemctl --user status deepdive.timer
systemctl --user list-timers --all | grep deepdive
```

To trigger a manual run via systemd:
```bash
systemctl --user start deepdive.service
journalctl --user -u deepdive.service -f
```

---

## Step 10: Monitoring & Rollback

### Monitor daily runs
```bash
journalctl --user -u deepdive.service --since today
```

### Check latest briefing
```bash
ls -lt ~/.cache/deepdive/briefing_*.json | head -1
```

### Disable timer (rollback)
```bash
systemctl --user stop deepdive.timer
systemctl --user disable deepdive.timer
```

### Clean reinstall
```bash
make clean
make install
make test
```

## Known Gaps & Mitigations

| Gap | Impact | Mitigation |
|-----|--------|------------|
| arXiv RSS empty on weekends | Empty briefing Sat/Sun | ArXiv API fallback is implemented |
| `feedparser` missing | RSS skipped | API fallback activates automatically |
| `localhost:4000` down | Synthesis uses template | Start LLM endpoint or update config |
| Piper model ~2GB download | First TTS run slow | Pre-download during `make install` |
| Telegram rate limits | Delivery delayed | Retry is manual; add backoff if needed |

---

## Sign-Off

| Check | Verified By | Date |
|-------|-------------|------|
| Dependencies installed | | |
| Secrets configured | | |
| TTS engine ready | | |
| LLM endpoint responding | | |
| Dry-run successful | | |
| Live run successful | | |
| Systemd timer active | | |
