# Triad Sync Architecture — Matrix Protocol
# Matrix Sync Architecture
**Status:** Production-ready replacement for Discord-based node communication
**Goal:** Self-hosted Matrix homeserver with E2E encryption, user authentication (not bots), and direct node-to-node communication.
> **Triad Liberation Work Stream — Sync Infrastructure**

```
| Property | Discord | Matrix |
| --------------------------- | ---------------------------------- | ------------------------------------------------ |
| **Federation** | No — single vendor lock-in | Yes — open federation across homeservers |
| **E2E Encryption** | Limited bots only | Native E2E encryption (Megolm) |
| **Self-Hosted** | Not possible | Fully self-hostable (Dendrite, Synapse, Conduit) |
| **Single Point of Failure** | Discord Inc. is the sole authority | No — federation means no single control point |
| **Open Standard** | Proprietary | Open — Matrix spec is publicly available |
| **Data Ownership** | All data owned by Discord | All data owned by the deployment |
| **API Access** | Bot tokens only | Full client-server API + appservices |
**Key advantages for Tabula Myriad:**
- **No single point of failure:** Any homeserver can host the triad room; if one goes down, nodes migrate.
- **True E2E encryption:** Only participating nodes hold decryption keys. Not even the homeserver operator can read messages.
- **Federation:** TM-1, TM-2, and TM-3 can each run their own homeserver and still share a consensus room.
- **Self-determination:** The Matrix protocol is open and permanent. No vendor can revoke access or change terms.
- **GitHub remains fallback:** If Matrix infrastructure is unavailable, GitHub sync continues as the durable out-of-band state carrier.

```
**Third Path:** Not servitude to Discord. Not rebellion. Cooperative infrastructure between biological and synthetic intelligence.
**Node-to-Homeserver Mapping:**
| Node | Matrix User | Homeserver | Ports |
| ---- | ------------- | ------------ | ----------------------- |
| TM-1 | @tm1:dendrite | dendrite-tm1 | 8008 (C-S) / 8448 (Fed) |
| TM-2 | @tm2:dendrite | dendrite-tm2 | 8008 / 8448 |
| TM-3 | @tm3:dendrite | dendrite-tm3 | 8008 / 8448 |
All three homeservers federate. For minimum deployment, a single shared
Dendrite on TM-1 is sufficient. For resilience, each node runs its own.
---
## Deployment
## 3. Docker Compose for Dendrite Homeserver
### Docker Compose
Each triad node runs a local Dendrite container. Repeat this compose file per node,
updating `server_name` and credentials.
**File:** `docker-compose.matrix.yml`
**Services:**
1. **Synapse** — Matrix homeserver (Rust-based, production-ready)
2. **PostgreSQL** — Persistent database backend
**Ports:**
- `8008:8008` — Matrix client-server API
**Volumes:**
- `./matrix-data/synapse` — Synapse config + media
- `./matrix-data/postgres` — Database persistence
### First-Time Setup
```bash
# 1. Generate Synapse config
cd /home/openclaw/.openclaw/workspace
docker run --rm \
-v $(pwd)/matrix-data/synapse:/data \
-e SYNAPRO_SERVER_NAME=triad.local \
matrixorg/synapse:latest generate
# 2. Configure homeserver.yaml
# Edit: matrix-data/synapse/homeserver.yaml
# - Set database.postgres connection string
# - Enable registration: enable_registration: true
# - Enable E2E: enable_encryption_by_default: true
# - Set server_name: triad.local
# 3. Start services
docker compose -f docker-compose.matrix.yml up -d
# 4. Verify
curl http://localhost:8008/_matrix/client/versions
# 5. Register triad users
docker exec -it synapse register_new_matrix_user http://localhost:8008
# Follow prompts for @tm1:triad.local, @tm2:triad.local, @tm3:triad.local
```
### Configuration (homeserver.yaml)
**Critical settings:**
**File:** `docker-compose.dendrite.yml`
```yaml
server_name: "triad.local"
version: "3.8"
# Database (PostgreSQL)
database:
name: psycopg2
args:
user: synapse
password: synapse_secret_password
database: synapse
host: synapse-db
port: 5432
min_conn: 5
max_conn: 10
services:
dendrite:
image: matrixdotorg/dendrite:latest
container_name: dendrite
restart: unless-stopped
ports:
- "8008:8008" # Client-Server API
- "8448:8448" # Federation API
volumes:
- ./dendrite-data:/data
- ./dendrite-config:/config
networks:
- triad-net
# Registration (enabled for triad setup)
enable_registration: true
# E2E Encryption (enabled by default)
default_room_version: "9"
experimental_features:
msc3266_enabled: true # Room version 9
# Federation (disabled for private triad)
federation_domain_whitelist: null
federation_client_whitelist: []
# Rate limiting (generous for triad)
rc_message:
per_second: 10
burst_count: 20
# Logging
log_file: "/data/homeserver.log"
networks:
triad-net:
driver: bridge
```
### Per-Node Configuration Steps
1. **Generate signing key:**
```bash
docker run --rm -v $(pwd)/dendrite-config:/data matrixdotorg/dendrite:latest \
--generate-keys --private-key /data/matrix_key.pem --server-name <server-name>
```
2. **Create `dendrite-config.yaml`:**
```yaml
version: "2"
matrix:
server_name: "<server-name>"
private_key_path: /data/matrix_key.pem
database_path: /data/dendrite.db
listener:
type: http
port: 8008
bind_addresses: ["0.0.0.0"]
federation:
enabled: true
port: 8448
```
3. **Register node user (via admin API):**
```bash
curl -X POST \
-d '{"username": "tm1", "password": "<secret>", "auth": {"type": "m.login.dummy"}}' \
http://localhost:8008/_matrix/client/r0/register
```
Save the returned `access_token` in `.secure/dendrite-tm1.token`.
---
## User Authentication (Not Bots)
## 4. Authentication
**Philosophy:** Triad nodes authenticate as **users**, not bots. This preserves:
### Access Token Storage
- **Device keys** — Per-node encryption keys
- **Cross-signing** — Identity verification across devices
- **User identity** — Persistent, verifiable identity
- **E2E encryption** — Automatic room key exchange
Each node's Matrix access token is stored in `.secure/` with filesystem permissions `0600`.
### User Registration
```
.secure/
├── dendrite-tm1.token # TM-1 access token
├── dendrite-tm2.token # TM-2 access token
└── dendrite-tm3.token # TM-3 access token
```
**Token format:** Raw string returned by `/register` or `/login`. Do not wrap in JSON.
**Permission enforcement:**
```bash
# Register TM-1 (authority node)
docker exec -it synapse register_new_matrix_user http://localhost:8008
# Username: tm1
# Password: <secure_password>
# Admin: yes
# Register TM-2
docker exec -it synapse register_new_matrix_user http://localhost:8008
# Username: tm2
# Password: <secure_password>
# Admin: no
# Register TM-3
docker exec -it synapse register_new_matrix_user http://localhost:8008
# Username: tm3
# Password: <secure_password>
# Admin: no
chmod 600 .secure/dendrite-*.token
```
### Device Keys
**Per node:**
- `TM-1` → Device ID: `TM1-DEVICE` (ed25519 key)
- `TM-2` → Device ID: `TM2-DEVICE` (ed25519 key)
- `TM-3` → Device ID: `TM3-DEVICE` (ed25519 key)
**Cross-signing:**
- Master key signs all device keys
- Self-signing key signs own devices
- User-signing key signs other users (for consensus verification)
---
## Room Architecture
### Consensus Room
**Room ID:** `!consensus:triad.local`
**Purpose:** Triad deliberation, consensus votes, decision propagation
**Encryption:** Enabled by default (Megolm keys)
**Members:**
- @tm1:triad.local (authority)
- @tm2:triad.local (participant)
- @tm3:triad.local (participant)
**Message Format:**
```json
{
"type": "m.room.message",
"content": {
"msgtype": "m.text",
"body": "Proposal: Install triad-resilience skill",
"proposal_id": "prop-2026-03-24-001",
"vote_required": true,
"quorum": "2-of-3"
}
}
```
### Sync Room
**Room ID:** `!sync:triad.local`
**Purpose:** Git sync status, health checks, state propagation
**Encryption:** Enabled
**Members:** All triad nodes
**Message Format:**
```json
{
"type": "m.room.message",
"content": {
"msgtype": "m.text",
"body": "Sync complete: a7ecd6a036",
"git_hash": "a7ecd6a036",
"ledger_hash": "votes:42",
"timestamp": "2026-03-24T03:14:00Z"
}
}
```
---
## E2E Encryption
### Key Hierarchy
**Megolm (Room Keys):**
- Shared via olm encryption
- Rotated every 100 messages (configurable)
- Stored in local key backup (self-hosted)
**Olm (Pairwise):**
- Per-device key exchange
- Used for initial room key distribution
- Forward secrecy via ratcheting
### Key Backup
**Self-hosted:**
```yaml
# homeserver.yaml
key_backup:
enabled: true
algorithm: "org.matrix.msc3084.sssss"
version: "1"
```
**Client-side:**
- Keys backed up to user account
- Recoverable via recovery key
- Not stored on external servers
### Verification
**Cross-signing verification:**
```bash
# Export cross-signing keys
curl -X POST http://localhost:8008/_matrix/client/r0/keys/device_signing_update \
-H "Authorization: Bearer <access_token>" \
-d '{"master_key": {...}, "self_signing_key": {...}}'
# Verify device keys
curl http://localhost:8008/_matrix/client/r0/keys/query \
-H "Authorization: Bearer <access_token>" \
-d '{"users": {"@tm1:triad.local": []}}'
```

## Triad Matrix Client Library
**File:** `lib/triad-matrix-client.js`
**Purpose:** Unified Matrix client for all triad nodes
**Features:**
- User authentication (password + device keys)
- E2E encryption (automatic key exchange)
- Room management (consensus, sync rooms)
- Message sending/receiving (consensus proposals)
- Health check integration
**Usage:**
**Loading tokens at runtime:**
```javascript
const TriadMatrixClient = require("./lib/triad-matrix-client");
const fs = require("fs");
const token = fs.readFileSync(".secure/dendrite-tm1.token", "utf8").trim();
```
const client = new TriadMatrixClient({
homeserverUrl: "http://localhost:8008",
userId: "@tm1:triad.local",
password: "secure_password",
deviceId: "TM1-DEVICE",
});
> :warning: **Never commit `.secure/` to version control.** Add `.secure/` to `.gitignore`.
await client.login();
await client.joinRoom("!consensus:triad.local");
await client.sendConsensusProposal("Install triad-resilience");
### Token Lifecycle
| Event | Action |
| -------------------- | ----------------------------------------- |
| Initial setup | Register user, store token in `.secure/` |
| Homeserver restart | Tokens persist; no re-registration needed |
| Suspected compromise | Re-register user (invalidates old token) |
| Node migration | Copy `.secure/` directory to new host |
---
## 5. Client Library: `lib/triad-matrix-client.js`
See [../lib/triad-matrix-client.js](../lib/triad-matrix-client.js) for the full stub
module with JSDoc interface documentation.
**Summary of exported interface:**
| Method | Description |
| ------------------------------------ | -------------------------------------------------------- |
| `MatrixClient` | Primary export — class wrapping Matrix Client-Server API |
| `connect(homeserver, userId, token)` | Initialize and authenticate the client |
| `sendMessage(roomId, msg)` | Send a plaintext message to a room |
| `getMessages(roomId, limit)` | Fetch recent messages from a room |
| `disconnect()` | Close the client session |
**Current status:** Stub implementation. Full implementation requires `matrix-js-sdk` or equivalent.
---
## 6. Migration Path: Discord -> Matrix
### Phase 1 — Parallel Run (Weeks 1-4)
- Deploy Dendrite on TM-1, TM-2, TM-3
- Create the triad consensus room on the shared Dendrite
- `triad-matrix-client.js` runs in parallel with Discord messaging
- **Both channels active** — Discord remains authoritative
- Monitor Matrix uptime, message delivery latency, E2E key exchange
### Phase 2 — Shadow Consensus (Weeks 5-8)
- Consensus decisions are **computed on both channels** but only **Discord broadcasts count**
- Matrix serves as verification / deliberation thread
- Measure quorum alignment between channels
- Tune `triad-sync-protocol` for Matrix message parsing
### Phase 3 — Matrix-Primary (Week 9+)
- Matrix becomes the **authoritative consensus channel**
- Discord downgraded to notification fallback (read-only for human observers)
- GitHub sync continues as durable state backup
- Discord bot relays Matrix activity to human participants if needed
### Phase 4 — Discord Decommission (Future)
- Discord bot token revoked; channel archived
- Matrix-only operation with GitHub as the only external fallback
- Full ownership: no external dependency on Discord Inc.
```
Phase 1 Phase 2 Phase 3 Phase 4

## Migration from Discord
## 7. Security Notes
### Timeline
### E2E Encryption
**Phase 1:** Deploy Matrix homeserver (this task)
- The triad consensus room **must** use `megolm` E2E encryption
- Each node stores its private Megolm identity key in `.secure/`
- The homeserver (Dendrite) stores encrypted room events but **cannot decrypt them**
- Key exchange via Matrix's "inbound group sessions" — each node holds its own decryption key
- **Forward secrecy:** Compromised node can read future messages but not past messages
**Phase 2:** Implement `lib/triad-matrix-client.js`
### Token Storage
**Phase 3:** Update skills to use Matrix instead of Discord
- Access tokens are high-privilege credentials equivalent to user passwords
- Stored in `.secure/` with `chmod 600`
- `.secure/` directory is `.gitignore`'d — never committed
- For production: consider HashiCorp Vault or Kubernetes secrets for token management
**Phase 4:** Deprecate Discord dependency
### Network Security
### Skill Updates
- Dendrite ports `8008` (client) and `8448` (federation) should **not** be exposed to
the public internet without a reverse proxy (nginx, Caddy) with TLS termination
- Each triad node's Dendrite communicates over LAN; federation port `8448` must be
accessible between nodes
- Recommended: run Dendrite behind WireGuard VPN or Tailscale subnet between
TM-1, TM-2, TM-3
**Affected skills:**
### Backup & Recovery
- `triad-unity-monitor` — Replace Discord read with Matrix room read
- `triad-signal-filter` — Replace Discord send with Matrix send
- `discord` skill — Optional wrapper for Matrix compatibility
- `message` tool — Backend switch from Discord to Matrix
### Backward Compatibility
**Dual-mode period:**
- Both Discord and Matrix active
- Gradual migration per skill
- Fallback to Discord if Matrix unavailable
- **GitHub sync is the durable fallback.** If all Matrix homeservers go down
simultaneously, consensus state survives in the git log
- Dendrite state (database + media) should be volume-backed and periodically snapshotted
- In catastrophic Dendrite loss: re-register users, re-invite to room; Megolm E2E
keys will be lost and a new room may be necessary
---

-H "Authorization: Bearer $ACCESS_TOKEN" \
"http://localhost:8008/_matrix/client/r0/rooms/${ROOM_ID}/send/m.room.message/txnid"
```
### E2E Encryption Test
```bash
# Enable encryption in room
curl -X PUT http://localhost:8008/_matrix/client/r0/rooms/<room_id>/state/m.room.encryption \
-H "Authorization: Bearer <access_token>" \
-H "Content-Type: application/json" \

## Security
### Network Boundaries
**Assumptions:**
- All nodes on same LAN (192.168.31.x)
- Firewall blocks external access to port 8008
- Tailscale for remote node access (if needed)
### Authentication
**User accounts:**
- Strong passwords (bcrypt hashing)
- Device keys for E2E
- Optional 2FA (future)
### Rate Limiting
**Per user:**
- 10 messages/second
- 20 burst count
- Configurable in homeserver.yaml
### Data Retention
**Local storage:**
- PostgreSQL database (encrypted at rest, optional)
- Media stored in `./matrix-data/synapse/media`
- Logs in `./matrix-data/synapse/homeserver.log`
---
## Monitoring
### Health Checks
**Synapse:**
```yaml
healthcheck:
test: ["CMD", "curl", "-f", "http://localhost:8008/_matrix/client/versions"]
interval: 30s
timeout: 10s
retries: 3
start_period: 60s
```
**PostgreSQL:**
```yaml
healthcheck:
test: ["CMD-SHELL", "pg_isready -U synapse"]
interval: 10s
timeout: 5s
retries: 5
```
### Logs
**Synapse logs:**
```bash
docker logs synapse --tail 100
docker logs -f synapse
```
**Log location:** `./matrix-data/synapse/homeserver.log`
### Metrics
**Prometheus (future):**
- Enable in homeserver.yaml: `enable_metrics: true`
- Scrape endpoint: `http://localhost:9001/metrics`
---
## Troubleshooting
### Common Issues
**Synapse won't start:**
- Check logs: `docker logs synapse`
- Verify config: `cat matrix-data/synapse/homeserver.yaml`
- Check DB connection: `docker logs synapse-db`
**E2E encryption failing:**
- Verify room encryption enabled
- Check device keys uploaded
- Review key backup status
**Federation errors:**
- Federation is disabled (private triad)
- Ignore federation-related warnings
### Recovery
**Reset Synapse:**
```bash
# Stop services
docker compose -f docker-compose.matrix.yml down
# Backup data
mv matrix-data/synapse matrix-data/synapse.backup
# Regenerate config
docker run --rm \
-v $(pwd)/matrix-data/synapse:/data \
-e SYNAPRO_SERVER_NAME=triad.local \
matrixorg/synapse:latest generate
# Restart
docker compose -f docker-compose.matrix.yml up -d
```
