# OpenSpec Change: network-trystero-server

- **Change ID**: network-trystero-server
- **Package**: `@suaveplan/network-trystero-server`
- **Category**: server (Node-only)
- **Target path**: `packages/network/network-trystero-server`
- **Status**: PROPOSED
- **Date**: 2026-05-11
- **Parent**: `network-transport-family` (2026-05-11) — Wave 5
- **Migration source**: `../suaveplan/packages/server/network-trystero-server` + `../suaveplan/enterprise/network-trystero-server.md`

## Summary

Migrate `@suaveplan/network-trystero-server` into genesis as a server-tier daemon. Hosts a Trystero serverless P2P signaling endpoint (MQTT broker or Nostr relay shim depending on configuration). Pairs with browser-tier `@suaveplan/network-discovery-trystero` (Wave 2) for the relay-backed transport modes.

## Parity Checklist

| Capability | Upstream | Migrated | Notes |
|---|---|---|---|
| Server daemon (Node) | ✅ | ✅ | |
| Trystero signaling endpoint | ✅ | ✅ | |
| Configurable transport (mqtt / nostr) | ✅ | ✅ | |
| Relay-URL bootstrap | ✅ | ✅ | |
| Structured errors | 🚫 | ⬆️ | `defineCodes` registry. |
| Zod boundary validation | 🚫 | ⬆️ | Every public option struct. |
| OTel instrumentation | 🚫 | ⬆️ | Spans + counters + histograms. |
| AbortSignal | 🚫 | ⬆️ | Threaded everywhere. |
| Health / readiness / liveness | 🚫 | ⬆️ | Via `@suaveplan/health-check` once that lands; otherwise inline endpoints. |
| `export *` barrels | check | ⬆️ | Convert to explicit named exports per §6a. |
| Test-runner imports | direct vitest | ⬆️ | Rewrite to `@suaveplan/testing/runner` per §7. |
| 100% test coverage | 🚫 | ⬆️ | Bring to 100/100/100/100. |
| Integration tests | partial | ⬆️ | Use `@suaveplan/testing-integration` for real-process tests; no mocks. |

## Available workspace deps on genesis

- `@suaveplan/network` ✅
- `@suaveplan/error`, `@suaveplan/types`, `@suaveplan/events`, `@suaveplan/logger`, `@suaveplan/retry`, `@suaveplan/timing` ✅
- `@suaveplan/testing` + `@suaveplan/testing-integration` ✅

- External: `trystero, (optional) mosca/aedes for MQTT broker`.

`package.json` declares `"engines": { "node": ">=20" }` and omits the `browser` field; server-tier marker comment in main entry point.

## Acceptance gate

1. `bunx turbo lint typecheck test --filter=@suaveplan/network-trystero-server` green.
2. `bunx turbo test:coverage --filter=@suaveplan/network-trystero-server` 100/100/100/100.
3. `bun run docs:check` green.
4. Integration test boots the server in-process and exercises the client-server round trip.
5. `STATUS.md` row flipped.

## Out of scope

- Production deployment infrastructure (Docker, k8s manifests, TLS termination) — deployment concern.
- Cross-cluster federation across multiple server instances.
