## Features

- **E2EE that actually works** - mautrix-go with goolm (pure Go). Crypto state lives in SQLite so device keys survive restarts. Cross-signing bootstraps on first run — the bot self-verifies its own device.
- **No CGo, no system deps** - builds to a single static binary. Cross-compile to whatever you want.
- **43 plugins** with dependency injection and ordered registration
- **Games & economy** - Euro virtual currency, Hangman (collaborative, threaded, tiered scoring), Blackjack (1-2 players, auto-play timeout), UNO (solo vs bot or 2–4 player multiplayer via DMs), all with channel restriction
- **Moderation system** (optional) - deterministic detection only, no LLM. Word list with leetspeak variation matching, text/image flood, repeated messages, mention flooding, link rate limiting, invite flooding, join/leave cycling. Three-strike ladder (warn → mute → ban). Admin room notifications, DMs over public callouts.
- **Passive tracking** - XP, stats, streaks, achievements, markov corpus, keyword alerts, all running silently
- **Scheduled posts** via [robfig/cron](https://github.com/robfig/cron) - WOTD, holidays, game releases, birthdays, anime/movie releases, concert digests, esteemed members
- **LLM integration** (optional) - Ollama-powered sentiment analysis, roast profiles, room vibes, tarot readings, conversation summaries
- **Encrypted quote wall** - AES-256-GCM encrypted quotes at rest, reply-to-save, search, leaderboard
- **Space groups** - automatic room grouping via membership overlap. Leaderboards, stats, and trivia scores span all rooms in a group. No Matrix Spaces API needed — the bot infers community boundaries from shared members.
- **SQLite everything** - one file, no external database needed

---

## Running the Bot

```bash
# dev
go run -tags goolm .

# prod
go build -tags goolm -o gogobee .
./gogobee
```

The `-tags goolm` flag selects the pure-Go crypto implementation. No C compiler or libolm needed.

### First Run

1. Start the bot. It logs in, creates a device, bootstraps cross-signing, and self-verifies automatically.
2. That's it. E2EE works across restarts from here on out.

## Sentiment Classification

Every message (subject to `LLM_SAMPLE_RATE`) is classified by Ollama into one of 10 sentiment categories. The bot reacts with an emoji when the confidence score is strong enough (|score| > 0.5). Per-user counts are tracked in the database and viewable via `!sentiment`.

| Sentiment | Emoji | Score range | Example |
|-----------|-------|-------------|---------|
| Positive | 👍 | > 0.5 | "This is awesome, great work!" |
| Excited | 🔥 | > 0.5 | "OH MY GOD I can't wait for this!!" |
| Supportive | 🤗 | > 0.5 | "You've got this, don't give up" |
| Grateful | 💜 | > 0.5 | "Thank you so much for helping me" |
| Humorous | 😂 | > 0.5 | "lmao that's the funniest thing I've seen all day" |
| Curious | 🧐 | > 0.5 | "How does that work exactly?" |
| Neutral | — | — | "I'll be back in 10 minutes" |
| Sarcastic | 🤨 | < -0.5 | "Oh sure, that'll definitely work" |
| Frustrated | 😮‍💨 | < -0.5 | "I've been trying to fix this for three hours" |
| Negative | 👎 | < -0.5 | "This is broken and nobody cares" |

The LLM also returns a float score (-1.0 to 1.0) for each message. These scores are averaged per user to derive an overall mood shown in `!sentiment` output and fed into `!howami` roast profiles.

### Why Go?

**E2EE** - This project went through three SDK iterations: `matrix-bot-sdk` (no E2EE support), `matrix-js-sdk` (E2EE via `fake-indexeddb` with an in-memory crypto store that wiped device keys on every restart), and finally `mautrix-go` which stores crypto state in SQLite with cross-signing bootstrap. The bot self-verifies its own device on startup.

**Deployment** - Pure Go, no CGo. `go build -tags goolm` gives you a static binary with zero system dependencies. The TypeScript version needed Node.js, npm, a C compiler for better-sqlite3, and libolm.

**Scheduler** - Replaced a hand-rolled 60s tick loop with robfig/cron. Standard cron expressions, less code, fewer bugs.

**Plugins** - Go interfaces + struct embedding instead of abstract classes. Same pattern, less boilerplate.

## Database

Single SQLite file at `$DATA_DIR/gogobee.db`. Schema auto-creates on first run. WAL mode enabled.

40+ tables covering users, XP, stats, streaks, reputation, reminders, trivia, achievements, encrypted quotes (AES-256-GCM), backlog, keyword watches, scheduler config, birthdays, horoscopes, LLM classifications, stocks, concerts, anime, movies, countdowns, presence, markov corpus, reaction log, and various caches.

### Backup

```bash
# safe to run while the bot is up (WAL mode)
sqlite3 data/gogobee.db ".backup data/gogobee-backup.db"
```

## Troubleshooting

### E2EE

E2EE should just work. The bot bootstraps cross-signing and self-verifies its device on first run.

1. After restarts, the bot reuses its saved device and crypto state. No manual steps needed.
2. If things are really broken, delete `data/device.json` and `data/gogobee.db` to start fresh.

### Bot not responding in encrypted rooms

- Check that the bot joined the room (it auto-joins on invite)
- Look at logs for decryption errors

### API commands not working

- Check that the relevant API key is set in `.env`
- Look at logs for error messages
- Most APIs have rate limits; the bot caches responses to stay within them

### Build errors about libolm

```bash
# use the goolm tag:
go build -tags goolm -o gogobee .
```
