# GogoBee

Matrix community bot with E2EE, 50 plugins, passive tracking, scheduled posts, and optional LLM features.

Written in Go using [mautrix-go](https://github.com/mautrix/go) for encryption and [modernc.org/sqlite](https://modernc.org/sqlite) for storage.

## 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.
- **50 plugins** with dependency injection and ordered registration
- **Games & economy** - Euro virtual currency, Hangman (collaborative, threaded, tiered scoring, multilingual clue mode via DreamDict, difficulty tier display), Blackjack (1-4 players, auto-play timeout), UNO (solo vs bot or 2–4 player multiplayer via DMs, with optional No Mercy mode), Texas Hold'em (2-9 players, CFR-trained NPC bot, DM-based gameplay with Ollama coaching tips, 1-hour idle auto-close with 45-min warning), Wordle (daily cooperative, DreamDict-powered, 5-20 letter words, guess persistence across restarts, midnight expiry announcements, video game themed bonus words with category hints, dupe prevention across last 500 puzzles, earnings tracked in stats), Adventure 2.0 (D&D-layered RPG: 7 races, 5 classes with 3 subclasses each through L15, real spell slots and forward-simulating combat engine, 10 hand-tuned dungeon zones across 5 tiers, multi-day expeditions with supply burn / threat clock / day cycle / multi-region travel / extract-and-resume / per-zone temporal events, harvest nodes per room, TwinBee as a mood-driven DM with ten zone-specific narration pools, all on top of the existing economy/housing/pets/Misty/Arina/blacksmith/hospital/rivals systems), Arena (5-tier combat gauntlet with 20 unique monsters, streak-based payouts, death lockout, leaderboard), Co-op Dungeons (2–7 day party runs with funding tiers, TwinBee-narrated floor events with voting, spectator parimutuel betting, basket/mimic gift system, weighted-roll item distribution including masterworks at T4–T5), 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.
- **Space inviter** (optional) - detects local homeserver users who aren't in any Matrix Space and DMs the configured admin to ask whether to invite them to a target Space. Replies are `yes` / `no` / `ignore`. Persistent prompt log in SQLite means restarts/upgrades don't re-ping the admin about users they've already answered. Runs on startup sweep + reactive on join events.
- **Passive tracking** - XP, stats, streaks, achievements, markov corpus, keyword alerts, all running silently
- **Scheduled posts** via [robfig/cron](https://github.com/robfig/cron) - Palavra do Dia (Portuguese WOTD with en/fr translations and etymology), 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
- **Markdown rendering** - auto-detects `**bold**`, `_italic_`, and `` `code` `` in messages and sends proper HTML to Matrix clients
- **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

## Installation

### From Source

```bash
git clone https://github.com/prosolis/gogobee.git
cd gogobee
cp .env.example .env   # edit with your settings
go build -tags goolm -o gogobee .
./gogobee
```

### Docker

```bash
docker build -t gogobee .
docker run --env-file .env -v ./data:/app/data gogobee
```

### Docker Compose

```bash
docker compose up -d
```

---

## Configuration

Everything is configured through environment variables or a `.env` file.

### Required

| Variable | Description |
|----------|-------------|
| `HOMESERVER_URL` | Matrix homeserver URL, e.g. `https://matrix.org` |
| `BOT_USER_ID` | Bot's Matrix user ID, e.g. `@gogobee:matrix.org` |

GogoBee authenticates via the **Matrix Authentication Service (MAS) OAuth 2.0
device grant** — no password or token in the environment. On first run it prints
a verification URL and user code; approve it once in a browser while logged in
as `BOT_USER_ID`. The bot then stores a refresh token in `DATA_DIR/mas_auth.json`
and refreshes its access token silently for the life of the deployment. Delete
`data/mas_auth.json` to force re-authorization. Requires a homeserver with MAS
enabled (advertised via the `org.matrix.msc2965.authentication` well-known).

## 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.

**DM commands during gameplay:** reply with a card number to play, `draw` to draw, `uno` to call UNO (required when you have 2 cards), `quit` to forfeit. During draw stacking, type `accept` to absorb the stack.

#### Classic Mode

Standard 108-card UNO deck. Draw one card per turn (pass if unplayable). Wild Draw Four can be challenged — if the challenger catches a bluff, the player draws 4 instead.

GogoBee has a personality system during solo play: she reads a book while playing, and puts it down when the game gets serious (opponent has few cards). Commentary changes based on book state.

#### No Mercy Mode

Based on UNO Show 'Em No Mercy (2023, Mattel). Bigger 168-card deck, meaner rules.

**New cards:**
| Card | Type | Effect |
|------|------|--------|
| Skip Everyone | Colored | Skips all other players — you go again |
| Discard All | Colored | Play it and discard every other card of that color from your hand |
| Draw Four | Colored | Like Wild Draw Four but matches by color (not wild) |
| Wild Reverse Draw Four | Wild | Reverse direction + draw 4 + pick a color |
| Wild Draw Six | Wild | Draw 6 + pick a color |
| Wild Draw Ten | Wild | Draw 10 + pick a color |
| Wild Color Roulette | Wild | Pick a color — next player flips cards from the deck until that color appears, keeping all flipped cards |

**Rule changes:**
- **Draw stacking** — when hit with a draw card, play a draw card of equal or higher value to pass the penalty to the next player. The stack keeps growing until someone can't (or won't) stack back. That player draws the entire total.
- **Draw until playable** — no more drawing one and passing. You keep drawing until you find a playable card.
- **Mercy rule** — reach 25 cards in your hand and you're eliminated.

#### 7-0 Rule (optional, No Mercy only)

Enabled by adding `7-0` to the command. When active:
- **Play a 7** — swap hands with another player of your choice (in multiplayer, you pick the target)
- **Play a 0** — all players pass their hand to the next player in play direction

#### Sudden Death

When a 2-player game (including bot matchups) exceeds 80 turns, a 20-turn countdown begins. At turn 100, both hands are scored by UNO card point values — lowest total wins. Tiebreaker: fewer cards, then advantage to the non-active player.

#### Multiplayer Bots

The default bot (GogoBee) is always present in multiplayer games. Up to 2 additional bots (WinBee, GwinBee) can be added via `!uno addbot` while the lobby is open. Addbot bots ante from the community pot, increasing the total pot. A single human can start a game if bots fill the remaining slots.

### Texas Hold'em (games channel only)

No-limit Texas Hold'em poker for 2-9 players. Buy-in is debited from your euro balance when you sit down; your remaining stack is cashed out when you leave. Private cards and coaching tips are delivered via DM — the room only sees start/end announcements.

An optional AI opponent (NPC) uses a CFR-trained poker solver. Add one with `!holdem addbot`.

| Command | Description |
|---------|-------------|
| `!holdem join` | Sit down at the table |
| `!holdem leave` | Leave the table (cashes out stack, shows refund) |
| `!holdem start` | Start dealing (2+ players) |
| `!holdem play` | Shortcut: join + start in one command |
| `!holdem addbot` | Add a CFR-trained AI opponent |
| `!holdem fold` | Fold your hand |
| `!holdem check` | Check (no bet to call) |
| `!holdem call` | Call the current bet |
| `!holdem raise <amount>` | Raise to a total of amount |
| `!holdem allin` | Go all-in |
| `!holdem status` | Current table state (sent via DM) |
| `!holdem help` | Show in-game help |

**DM commands:** `!holdem tips on/off` — toggle coaching tips (equity + pot odds analysis, powered by Ollama with rules-based fallback).

**Idle timeout:** Tables with no hands dealt close after 1 hour. A warning is posted at 45 minutes.

#### NPC Bot

The NPC opponent uses Counterfactual Regret Minimization (CFR), specifically the External Sampling variant of Monte Carlo CFR. Instead of hardcoding poker strategy, the bot learns one through millions of rounds of self-play. On each iteration, it plays both seats of a heads-up hand, tracks how much it "regrets" not having taken each alternative action, and gradually shifts its strategy toward the actions it regrets not taking. Over time, the strategy converges toward a Nash equilibrium — a point where no single change in play can improve its expected winnings against a perfect opponent. The trained policy ships as a single `.gob` file loaded at startup, and the bot plays a mixed strategy: it doesn't always make the same play in the same spot, but randomizes according to its trained probability distribution, which makes it harder to exploit.

The interesting engineering is in the abstraction layer. Real poker has roughly 10^17 possible game states — far too many for a tabular approach. We collapse this space down to around 23,000 information sets by bucketing hand strength into 12 equity tiers (computed via Monte Carlo rollout against random opponent hands), classifying boards as dry, wet, or paired based on flush/straight draw density and board pairing, tracking stack-to-pot ratio across 5 buckets, and encoding the last 6 actions as a compressed history string. All of this gets packed into a single `uint64` key — no string formatting, no allocations on the hot path. Preflop hands use a lookup table of the 169 strategically distinct hold'em starting hands, which eliminates Monte Carlo during the most frequently visited part of the game tree. Training runs at about 5 million iterations across all CPU cores with shared regret tables, periodic checkpointing, and regret pruning after a 500K warmup to skip deeply negative branches. The result is a bot that plays a solid, unpredictable game — not world-class, but strong enough to make the table interesting.

#### Training the NPC

A standalone training CLI is provided under `cmd/holdem-train/`. It requires the `training` build tag:

```bash
# Build the training CLI
go build -tags training -o holdem-train ./cmd/holdem-train/

# Train with 8 workers (defaults to all CPU cores if --workers is omitted)
./holdem-train --iterations 5000000 --workers 8 --output data/policy.gob

# Resume from a checkpoint
./holdem-train --iterations 5000000 --workers 8 --resume data/policy.gob.checkpoint --output data/policy.gob

# Validate the trained policy (10K hands vs random baseline)
./holdem-train --validate --output data/policy.gob
```

| Flag | Default | Description |
|------|---------|-------------|
| `--iterations` | `5000000` | Number of training iterations |
| `--workers` | `runtime.NumCPU()` | Parallel workers |
| `--output` | `data/policy.gob` | Output policy file |
| `--resume` | | Resume from checkpoint |
| `--validate` | `false` | Run validation instead of training |
| `--checkpoint-every` | `500000` | Checkpoint interval |
| `--seed` | `42` | Random seed |

Progress is logged with overall completion percentage and ETA. Checkpoints are saved every 30 seconds during parallel training.

### Wordle (games channel only)

Daily cooperative Wordle — one puzzle per day, the community works together with a shared 6-guess limit. Word selection powered by DreamDict with a bundled word list as fallback. A new puzzle auto-posts at midnight UTC. Word length is configurable (5-20 letters). Guesses persist across bot restarts. When a puzzle expires at midnight, the bot reveals the answer and announces it to the room. The puzzle pool includes video game themed words (loaded from `data/wordle_games.txt`) — when one is selected, a category hint is shown. Duplicate prevention ensures the same word won't appear within the last 500 puzzles.

| Command | Description |
|---------|-------------|
| `!wordle <word>` | Submit a guess for today's puzzle |
| `!wordle grid` | Re-post the current puzzle grid |
| `!wordle stats` | All-time leaderboard with community streak |

### Adventure (DM-based RPG)

A layered RPG. **Adventure 2.0** grafts a full D&D-style character system on top of the existing adventure economy, then builds two endgame loops on top of that: single-session dungeon zones and multi-day expeditions. The legacy systems — housing/Thom Krooke, pets, Misty/Arina, blacksmith, hospital, rivals, Robbie, arena, co-op dungeons — all keep working unchanged. Players who don't opt into 2.0 keep the legacy adventure shape; players who run `!setup` get the full D&D layer on top.

Characters auto-create on first interaction. Most gameplay happens in DMs — the morning prompt routes to zones/expeditions for the active flow plus in-town services (shop, blacksmith, rest, hospital, Thom Krooke) for the rest.

#### Adventure 2.0 — D&D Layer

`!setup` once. Pick a race + class. Your existing `combat_level` becomes your D&D level, treasures become attunements, equipment slots carry forward 1:1. Every fight, harvest, arena run, and co-op dungeon is then resolved through D&D mechanics — STR/DEX/CON/INT/WIS/CHA, HP, AC, ability checks, saving throws, all the rest.

**Races (7) — at race choice, fixed stat mods + a passive:**

| Race | Mods (S/D/C/I/W/Ch) | Passive |
|---|---|---|
| Human | 0/0/0/0/0/0 | Versatile (floating +1 not yet wired) |
| Elf | 0/+2/-1/+1/+1/0 | Darkvision; immune to sleep effects |
| Dwarf | +1/-1/+2/0/+1/-1 | Poison resistance; bonus vs. underground |
| Halfling | 0/+2/0/0/+1/0 | Lucky: once per combat, reroll a nat 1 |
| Orc | +3/-1/+2/-1/-1/-1 | Rage: once per combat, +50% damage for one turn |
| Tiefling | 0/+1/0/+1/0/+2 | Fire resistance; bonus on CHA checks |
| Half-Elf | 0/+1/0/+1/0/+2 | Two bonus skill proficiencies |

**Classes (5):** Fighter (d10 HP, STR/CON), Rogue (d8, DEX/INT), Mage (d6, INT/WIS), Cleric (d8, WIS/CHA), Ranger (d8, DEX/WIS).

**Subclasses** unlock at L3 via `!subclass`. Each class has 3 archetypes with mechanical features at L5/L7/L10/L15:

| Class | Subclasses |
|---|---|
| Fighter | Champion, Battle Master, Berserker |
| Rogue | Thief, Assassin, Arcane Trickster |
| Mage | Evocation, Abjuration, Necromancy, Arcane Trickster |
| Cleric | Life, War, Trickery |
| Ranger | Hunter, Beast Master, Gloom Stalker |

**Spells.** Mages, Clerics, and Rangers cast for real. Spell slots tracked, combat consumes them. Mages have a spellbook cap that grows with level — pick what to learn at level-up via `!learn`.

**Combat engine.** Forward-simulating turn-by-turn — d20 vs AC for every attack, hit/crit/miss/fumble narration with surfaced roll values (`(🎲 14 vs AC 13)`), monster abilities, status effects, class resources, consumables. Outcomes stream over 2–3 second pacing for suspense, with a roll summary appended.

**Dungeon zones (`!zone`)** — 10 hand-tuned zones, 5 tiers, level bands L1–L20:

| Tier | Zones |
|---|---|
| T1 | Goblin Warrens, Crypt of Valdris |
| T2 | Forest of Shadows, Sunken Temple |
| T3 | Haunted Manor, Underforge |
| T4 | Underdark Outpost, Feywild Crossing |
| T5 | Dragon's Lair, Abyss Portal |

Each run is procedurally laid out (entry → exploration → trap → elite → boss with exploration filler). TwinBee narrates as a mood-driven DM (0–100 mood, shifts on crits/deaths/taunts/zone completion). `!zone enter`, `!zone advance` to resolve the current room, `!zone status`, `!zone map` (ASCII layout `E──?──T──★──☠`), `!zone lore`, `!zone taunt` / `!zone compliment` to poke or flatter your DM.

**Multi-day expeditions (`!expedition`)** — the long form:

- **Outfitting:** buy supply packs at start (standard/deluxe), cost scales with zone tier
- **Real-time day cycle:** 06:00 morning briefing, 21:00 evening recap (configurable)
- **Supply burn:** rations tick down each day; harsh zones burn faster; running out triggers forced extraction
- **Threat Clock (0–100):** every action is noticed. Crossing bands shifts monster density, patrol odds, night events: Quiet → Stirring → Alert → Hostile → Siege
- **Patrol encounters** at Alert+ — fights interrupt traversal
- **Night phase / wandering monsters** — checked at the recap
- **Siege Mode (threat 80+):** fortified camp branches, special warnings
- **Camp:** `!camp rough` (free, no protection) vs `!camp standard` (consumes supplies, grants overnight rest)
- **Milestones:** First Night, Deep Dive, Long Haul, Survivalist, etc.
- **Expedition log** (`!expedition log`) — every event recorded

**Multi-region zones.** T4+ zones have multiple connected regions. `!region` shows where you are, where you can travel, and visited set. Inter-region travel consumes supplies and ticks threat. Base camp is a persistent waypoint per expedition. `!map` renders the full multi-region map.

**Per-zone temporal events** (signature time-based effects on every T2+ zone):

- **Sunken Temple** — tidal cycle floods/recedes rooms
- **Haunted Manor** — nightly reset; cleared rooms come back
- **Underforge** — heat accumulation; gear damage rises
- **Feywild Crossing** — time distortion; days pass at non-uniform rates
- **Dragon's Lair** — awareness pulses warn the dragon directly
- **Abyss Portal** — destabilization stack threatens forced collapse

**Extract & resume.** `!extract` bails safely from an expedition. Loot/XP/coins kept, expedition flips to `extracting` status, `!resume` within 7 days picks up from base camp.

**Harvest.** `!forage` / `!mine` / `!fish` / `!scavenge` / `!essence` / `!commune` work in cleared rooms during expeditions, and (Phase R) in single-session `!zone enter` runs too — per-room nodes seeded from the zone resource pool, finite charges, class-specific yield bonuses (Ranger forage/fish, Fighter mine), `!resources` to see what's gatherable. Zone-condition events (tidal block, heat block, manor cursed trinket drops) layer on during expeditions.

**Boss combat.** Every zone's boss is in the bestiary with its own stat block and phase-two narration crossing 50% HP. Win drops the per-zone loot table; T5 always drops a masterwork.

**HP scale.** D&D HP is the source of truth (your sheet says, e.g., `33 max`). The combat engine internally uses a legacy HP scale (calibrated for the old `combat_level`-based curves, ~123 max for a high-level player), but combat outcomes are translated back to D&D scale before display: `HP 33→26 / 33` is what you see, never the engine's internal numbers.

**Holidays.** On recognized holidays (~20/year, religious + cultural calendars), runs start with TwinBee mood +5, expedition outfitting includes a free standard pack, and harvest yields +1 per attempt. Hospital surcharge still applies on holiday deaths.

**Player commands cheat sheet:**

**Compatibility.** Adv 2.0 is fully additive — every pre-2.0 column on `adventure_characters`, `adventure_equipment`, `adventure_inventory`, `adventure_treasures`, `arena_stats`, etc. is preserved with original semantics. Migrations are column-adds with defaults only. Players who haven't run `!setup` keep the legacy adventure shape. `combat_level` becomes the D&D level; treasures become attunements; equipment slots carry forward unchanged.

#### Legacy adventure surface (still active)

The pre-2.0 town economy and supporting systems still work alongside the D&D layer.

| Command | Description |
|---------|-------------|

#### Skill tracks

Four skills are tracked separately from D&D level: **Combat (legacy)**, **Mining**, **Foraging**, **Fishing**. They gain XP from harvesting in zones, arena fights, encounters, and (legacy) babysitter actions. Skill levels gate masterwork drops, fishing-zone proficiency bonuses, and crafting recipe unlocks.

#### Mechanics

- **Equipment** — 5 slots (weapon, armor, helmet, boots, tool) with tiered upgrades from the shop. Equipment degrades on bad outcomes and breaks at 0 condition.
- **Masterwork gear** — rare skill-specific equipment drops from gathering activities (mining, fishing, foraging). 15 items across 5 tiers with decreasing drop rates (5% T1 down to 0.5% T5). Location-gated — drops only at matching tier. Auto-equips if better than current gear; otherwise goes to inventory for manual equipping via `!adventure equip`. Masterwork items provide a +5% skill bonus when the item's source skill matches the current activity. Character sheet marks masterwork items with a star.
- **Treasures** — rare collectibles (up to 3) that provide passive bonuses (XP multipliers, death chance reduction, loot quality). Prompted to discard when at cap.
- **Streaks** — consecutive days of activity grant escalating bonuses (XP, loot quality, death chance reduction). Resting resets your streak. Dead players' streaks are frozen — you won't lose your streak to involuntary downtime.
- **Grudge** — dying at a location marks it as your grudge. Returning there grants +10% success and +25% XP. Clears on success.
- **Death** — locked out for 6 hours. Natural respawn happens automatically when the timer expires. Use `!hospital` for immediate revival at a cost. Death's Reprieve (surviving a lethal roll) sets all equipment to 1 condition instead of destroying it. Dead players' streaks are preserved with a grace period — if you die and can't act on revival day, your streak won't reset.
- **Holidays** — on recognized holidays (~20/year across religious and cultural calendars), runs start with TwinBee mood +5, expedition outfitting includes a free standard pack, and harvest yields +1 per attempt. Hebrew and Islamic calendar support for floating holidays.
- **TwinBee** — narrates as a mood-driven DM during zone runs and expeditions (see Adv 2.0 above). The legacy daily activity loop is retired in favor of zones/expeditions; the babysitter (below) is the surviving "TwinBee runs an action for you" surface.
- **Hospital** — St. Guildmore's Memorial Hospital offers same-day revival for dead players. The bill is comically inflated (€125k × combat level) but guild insurance covers 80%, leaving €25k × combat level. Players who can't afford it are discharged back to the natural respawn queue. Nurse Joy provides the bedside manner.
- **Robbie the Friendly Bandit** — an automated NPC who visits at a random hour each day (8:00–21:00 UTC). Robbie takes sub-tier gear from your inventory (shop gear below your equipped tier, masterwork gear you've outgrown), leaves €50 per item as a "handling fee," and donates everything to the community pot. If he takes masterwork gear and you don't already have one, he drops a "Get Out of Medical Debt Free" card. No player command — Robbie comes to you.
- **Mid-day events** — random events can trigger between actions, delivering bonus loot, buffs, or narrative encounters.
- **Chat level perks** — active chat participation boosts your adventurer. +5% XP per 10 chat levels (capped at +25% at level 50+), plus +0.5% rare drop chance per 10 levels.

#### Crafting

Auto-crafting kicks in at Foraging Lv.10. Before each combat action, the system scans your inventory for matching ingredients and assembles the highest-tier recipe you qualify for. 12 recipes spanning T1–T5, gated at Foraging 10/15/20/25/30. Per-recipe success rate is 50% at the unlock level, +3% per 5 levels above (capped 95%). Failed crafts destroy the ingredients — you tried.

Per attempt:
- **Successful crafts** grant Foraging XP (T1: +12, T2: +25, T3: +40, T4: +60, T5: +90) and bump a lifetime `CraftsSucceeded` counter shown on `!adventure status`.
- **Failed crafts** grant a token Foraging XP (1/4 of success).

Max auto-crafts per combat scales with level: 1 at Foraging 10, 2 at 20, 3 at 30+.

`!adventure recipes` lists every recipe unlocked at your current Foraging level with ingredients and per-recipe success rate, plus a teaser for the next unlock threshold.

**Consumable protection:** crafted/dropped consumables (Type `consumable`) are excluded from `!adventure sell all` and Robbie the Friendly Bandit's pickup filter. Selling consumables requires explicit `!adventure sell <name>` — no accidental mass-sells, no surprise donations to the community pot.

#### Blacksmith & Repair

Equipment accumulates damage on bad outcomes and breaks at 0 condition. The blacksmith repairs gear for a per-point fee that scales with tier (base rates T0→T5: €1, €2, €5, €12, €30, €80; masterwork and arena gear use the next tier up). The cost has a mild convexity (`baseRate × damage × (1 + damage/200)`), so repairing earlier is slightly cheaper per point than letting gear sit at low condition — but not punitively so. `!adventure blacksmith` previews quotes; `!adventure repair all` or `!adventure repair <slot>` commits.

#### Babysitting Service

Busy days? Hire TwinBee to harvest on your behalf. Daily cost is `€100 + combatLevel × €20`. TwinBee trains your weakest gathering skill (mining/fishing/foraging) each day, so the service doubles as catch-up for neglected tracks. Subscribe by the week or month, or check/cancel anytime: `!adventure babysit week|month|status|cancel`.

#### Rival Duels

At combat level 5 and above you're entered into the rival pool. Every 3–4 days a random eligible player is matched as your rival and challenges you to a rock-paper-scissors duel via DM. You have 24 hours to accept and play. Stake is `(combatLevel / 5) × €1,000`, winner-take-all. Use `!adventure rivals` to see the pool and open challenges.

#### Housing & Mortgage (Thom Krooke)

Thom Krooke is the guild's housing broker. Four tiers are available:

| Tier | Name | Price |
|------|------|-------|
| 1 | Base | €75,000 |
| 2 | Livable | €150,000 |
| 3 | Comfortable | €300,000 |
| 4 | Established | €600,000 |

Buy outright or finance with a mortgage. Rates track the real-world US 5/1 ARM via the FRED API (`MORTGAGE5US` series; requires `FRED_API_KEY`, defaults to 6.5% if unset). Autopay pulls from your euro balance each day. Commands: `!thom shop`, `!thom buy <tier>`, `!thom pay <amount>`, `!thom payoff`, `!thom autopay on|off`, `!thom petbuy`.

#### Pets

Once you reach the Livable tier (HouseTier ≥ 2) a stray pet may show up at your door — 15% daily chance. When a pet arrives you'll get a DM prompt to `chase` it away or `feed` it to adopt. Each pet interaction grants +1.5 XP to a random skill. At pet Level 10, Thom unlocks pet armor for purchase (`!thom petbuy <tier>`).

#### Guest NPCs — Misty & Arina

Two rotating guest adventurers can be hired to join you on encounters:

- **Misty** — €100 hire fee, 7-day cooldown.
- **Arina** — €5,000 hire fee, 7-day cooldown.

After hiring, there's a 7.5% chance per action over the next 7 days that your NPC shows up mid-adventure and applies a buff to the outcome.

#### Arena (`!arena`)

A multi-tier combat gauntlet independent of the daily adventure action. Fight through 5 tiers of 4 rounds each — 20 unique named monsters with escalating lethality. Earnings accumulate across rounds but are forfeited on death. After clearing a tier, choose to descend deeper (keep earnings at risk) or cash out. Death locks you out of both arena and adventure for 6 hours. Each fight produces a turn-based combat log (Dragon Quest style) with fabricated HP pools and action narration — the outcome is determined by the roll, the log is assembled backward from the result. Arena losses award +60 participation XP.

| Command | Description |
|---------|-------------|
| `!arena` | Show the arena tier menu |
| `!arena tier <1-5>` | Select a tier (shows confirmation with R1 opponent) |
| `!arena fight` | Confirm entry / fight current round |
| `!arena cancel` | Back out of tier selection |
| `!arena descend` | Descend to next tier after clearing (earnings carry over, still at risk) |
| `!arena cashout` | Take your earnings and leave |
| `!arena stats` | Your personal arena stats |
| `!arena status` | Current run state |
| `!arena leaderboard` | Top arena players |
| `!arena help` | Arena help text |

**Mechanics:**
- **Death chance** — based on monster lethality, combat level, equipment tier, and battle skill. Clamped between 1% and 98%.
- **Rewards** — tier base payout * round number + battle skill * tier multiplier. Higher tiers and later rounds pay more.
- **Auto-cashout** — 10 minutes to decide after clearing a tier. GogoBee cashes out on your behalf if you're slow.
- **Tier entry confirmation** — `!arena tier N` previews the first opponent; `!arena fight` commits.

#### Co-op Dungeons (`!coop`)

Multi-day party runs separate from solo. 2–4 players, 2–7 days depending on tier, scaled rewards, and a public game-room thread the whole community watches. The combat action is consumed once at lock; subsequent days only ask for a daily funding decision (harvest activities continue normally).

| Tier | Days | Difficulty | Reward Pool | Optimal Funding |
|------|------|------------|-------------|-----------------|
| 1 | 2 | Moderate | €22,500 | Minimal/Standard |
| 2 | 3 | Hard | €40,000 | Standard |
| 3 | 4 | Very Hard | €72,500 | Standard |
| 4 | 5 | Brutal | €120,000 | Standard or Aggressive |
| 5 | 7 | Murderous | €600,000 | Aggressive (must commit) |

| Command | Description |
|---------|-------------|
| `!coop list` | Show open invites |
| `!coop start <1-5>` | Open an invite (24h window, pinned in the games room) |
| `!coop join [<id>]` | Join an open invite (defaults to most recent) |
| `!coop fund <tier>` | Set today's funding (`none` / `minimal` / `standard` / `aggressive` / `all_in`) |
| `!coop vote <A\|B\|C>` | Vote on the day's TwinBee-narrated floor event |
| `!coop bet <amount> <success\|failure>` | Spectator parimutuel bet (10% rake) |
| `!coop gift <run_id> <basket\|mimic>` | Send a gift (1 harvest action) |
| `!coop giftvote <id> <open\|leave>` | Party votes whether to open a received gift |
| `!coop status` | Your current run state |
| `!coop stats` | Community-wide aggregates: outcomes, gold flow, betting, gifts, helpfulness |
| `!coop cancel` | Leader cancels an open invite before lock |
| `!coop admgift <run_id> <basket\|mimic> [sender]` | Drop a gift into an active run, bypassing party-member and harvest-action checks (admin only — debug/testing) |
| `!coop help` | Co-op command list |

**Funding tiers** add to the per-floor success modifier: None −10%, Minimal +0%, Standard +8%, Aggressive +18%, All-In +30%. None is free; Minimal €500/day; Standard €1,500; Aggressive €4,000; All-In €10,000. Funding is non-refundable. Inactive players auto-play None.

**Floor events.** TwinBee narrates 1 of 4 categories per floor (Obstacle / Opportunity / Crisis / Encounter), tier-weighted. Each event has 2–3 options; majority vote wins, ties go to the leader, leader has the casting tiebreak. TwinBee always recommends an option — he is wrong roughly half the time. The party's vote modifier (−15 to +12 per floor depending on the option) stacks on the funding modifier. The 95% per-floor success cap means once you're saturated, more funding is wasted.

**Party strength factors.** Each member contributes a small per-floor modifier based on their combat level relative to the tier minimum (clamped ±8) plus a pet bonus (max +2.5 at pet level 10). A maxed veteran party at T5 can succeed at Standard funding where a fresh party would need Aggressive.

**Newbie liability.** Players below a tier's minimum combat level are flagged in the party post and capped at +8% funding modifier regardless of how much they pay. The party chose to let them in. Their reward share is unchanged — the cost is borne by the funding economy, not the post-run split.

**Spectator betting.** Parimutuel pool, 10% rake. Bets can be placed or increased any time during the run; positions are locked in (success or failure can't be switched). Party members can bet on their own run — sandbagging while heavily bet against is exploitative and visible. Odds line shows estimated success% based on party levels, pets, neutral funding assumption, and a hidden TwinBee Helpfulness Rating (rolling last 30 floor events: how often his recommendation was right). Helpfulness shifts the line ±20% but is never shown directly — players notice the line moves after events resolve.

**Gifts.** Anyone *not* in the run can spend one harvest action to send a Care Basket or a Mimic. The party never sees which type. Vote `open` or `leave`. **Each gift's voting window is 6 hours**; voting closes when it elapses, the stack is tallied, and every sender gets a DM with the result. The modifier sits on the run until the next floor resolution merges it in. Gifts "fire" throughout the day rather than piling up at the daily tick. Magnitudes are equalized across all four outcomes — both "always open" and "always leave" yield EV=0 with σ=6, so neither is risk-averse-dominant. The choice is purely about reading sender intent.

**Stacking.** Multiple gifts of the same type sent on the same day **stack into a single game-room post** — one vote covers the whole stack, modifier scales with size (5 baskets opened = +30%, 5 baskets exploded = −30%). The first-in sets the deadline; subsequent additions inherit it without extending the timer. When a stack hits size 2, TwinBee notes "this gift looks REALLY special" once and then quietly bumps the count on further additions. The end-of-run gift log groups by stack with all senders attributed.

|             | Open | Leave |
|-------------|------|-------|
| **Care Basket** | +6% (boost) | −6% (basket explodes) |
| **Mimic**       | −6% (mimic does what mimics do) | +6% (sad mimic helps anyway) |

Multiple gifts stack additively — coordinated senders can swing odds significantly. The full gift log is public at end of run.

**Loot.** On success, gold pool splits evenly (5% community tax). 2–6 items drop from the corresponding solo dungeon loot table (count scales with tier). Each item goes to a member via weighted roll — your share of total funding is your odds. **T5 always drops a masterwork**; T4 has a 25% chance. Masterworks go to inventory (not auto-equipped) so winners with better gear can sell or trade.

**Wipes.** No reward. Funding is gone. No combat-action refund (the tick already gave you a fresh one at midnight). Bet pool pays out to the failure side. The dungeon does not editorialize.

**Pinning.** Invite posts are pinned in the games room when opened, unpinned when the run locks or cancels. Bot needs power level for state events.

## Sentiment Classification

Every message (subject to `LLM_SAMPLE_RATE`) is classified by Ollama into one of 10 sentiment categories. Per-user counts are tracked in the database and viewable via `!sentiment`. The LLM also returns a float score (-1.0 to 1.0) for each message, averaged per user to derive an overall mood shown in `!sentiment` output and fed into `!howami` roast profiles.

Selective emoji reactions are still active: 🎓 for fancy/uncommon words, 💜 for gratitude, and 📖 for WOTD usage. The bot also reacts when insulted. Sentiment and profanity emoji reactions are disabled — classification still runs and logs to the database, but the bot won't react with sentiment emojis.

| Sentiment | 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" |

### 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.

80+ 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, market snapshots, forex rates/alerts, concerts, anime, movies, countdowns, presence, encrypted markov corpus, reaction log, miniflux RSS subscriptions, 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 .
```
