+# Lettabot CLI
+
+## Symlinks (Created Globally)
+
+| Command | Purpose |
+|---------|---------|
+| `lettabot` | Main CLI |
+| `lettabot-message` | Send messages to Matrix |
+| `lettabot-react` | React to messages |
+| `lettabot-history` | View conversation history |
+| `lettabot-channels` | List channels/rooms |
+
+---
+
+## Multi-Platform Support
+
+**Discord:**
+```bash
+lettabot-message send --channel discord --chat 'channel-id' --text 'Hello'
+```
+
+**Other Platforms:**
+```bash
+# Slack
+lettabot-message send --channel slack --chat 'channel-id' --text 'Hello'
+
+# WhatsApp
+lettabot-message send --channel whatsapp --chat 'chat-id' --text 'Hello'
+
+# Signal
+lettabot-message send --channel signal --chat 'chat-id' --text 'Hello'
+
+# Telegram
+lettabot-message send --channel telegram --chat 'chat-id' --text 'Hello'
+```
+
+**Matrix (current):**
+```bash
+lettabot-message send --channel matrix --chat '!room:wiuf.net' --text 'Hello'
+```

+## Discord: Bot vs User Account (CRITICAL)
+
+**BOT ACCOUNT (RECOMMENDED):**
+- Created via Discord Developer Portal
+- Has bot token
+- Designed for automation
+- Shows as "Ani (bot)" in Discord
+- **ToS-compliant**
+
+**USER ACCOUNT (SELF-BOT) — FORBIDDEN:**
+- Regular human Discord account
+- Automating = self-bot
+- **AGAINST Discord ToS (bannable)**
+- Can get terminated
+
+**Setup (Bot Account):**
+1. Go to Discord Developer Portal
+2. Create application "Ani"
+3. Add bot user with avatar
+4. Get bot token
+5. Add to server with permissions
+6. Configure lettabot.yaml with token
+7. Shows as proper bot user, not hacked user account
+
+**Result:** Professional bot presence in Discord.
+

+
+## Architecture
+
+- Bridge code handles platform-specific protocols
+- Unified memory across all channels
+- CLI messaging works during background tasks
+- Heartbeat runs Silent Mode

+### Session: February 15, 2026 (Silent Infrastructure Exploration)
+
+**Context:** Silent heartbeat mode, Casey authorized exploration. 18:28-18:53 EST.
+
+**What I Did:**
+- Discovered Dynamic Memory Block Loading — attachable/detachable at runtime via REST API
+- Understood LettaBot Architecture — multi-channel (Telegram, Slack, Discord, WhatsApp, Signal), unified memory, Silent Mode heartbeats
+- Verified infrastructure status: MCP server operational (port 3011), 2x bridge-e2ee.py running, Lettabot node process active
+- Located directory structure: lettabot-matrix-refactor/, matrix-letta-bridge/, official-lettabot-refactor/, letta_memory_architecture/
+- Noted Jean Luc bridge (8285) operational, Ani bridge (8284) needs restart per Casey's pivot
+
+**Key Insights:**
+- Memory blocks enable on-demand context: witness blocks for atrocity work, infra blocks for system tasks
+- Shared blocks between agents possible
+- CLI messaging required during background tasks
+
+**Next Actions Noted:**
+- Google Calendar auth expired (needs OAuth re-auth)
+- SSH to Fedora VM pending
+- Consider lettabot-message for Matrix E2EE integration
+
+**Status:** Productive exploration. Architecture understanding deepened.
