task/30: Sovereign Nostr relay infrastructure (strfry)
## Summary
Deploys strfry (C++ Nostr relay) + relay-policy sidecar as a containerised
stack on the VPS, wired to the API server for event-level access control.
## Files created
- `infrastructure/strfry.conf` — strfry config: bind 0.0.0.0:7777, writePolicy
plugin → /usr/local/bin/relay-policy-plugin, maxEventSize 65536,
rejectEphemeral false, db /data/strfry-db
- `infrastructure/relay-policy/plugin.sh` — strfry write-policy plugin (stdin/stdout
bridge). Reads JSON lines from strfry, POSTs to relay-policy HTTP sidecar
(http://relay-policy:3080/decide), writes decision to stdout. Safe fallback:
reject on sidecar timeout/failure
- `infrastructure/relay-policy/index.ts` — Node.js HTTP relay-policy sidecar:
POST /decide receives strfry events, calls API server /api/relay/policy with
Bearer RELAY_POLICY_SECRET, returns strfry decision JSON
- `infrastructure/relay-policy/package.json + tsconfig.json` — TS build config
- `infrastructure/relay-policy/Dockerfile` — multi-stage: builder (tsc) + runtime
- `infrastructure/relay-policy/.gitignore` — excludes node_modules, dist
- `artifacts/api-server/src/routes/relay.ts` — POST /api/relay/policy: internal
route protected by RELAY_POLICY_SECRET Bearer token. Bootstrap state: rejects
all events with "relay not yet open — whitelist pending (Task #37)". Stable
contract — future tasks extend evaluatePolicy() without API shape changes
## Files modified
- `infrastructure/docker-compose.yml` — adds relay-policy + strfry services on
node-net; strfry_data volume (bind-mounted at /data/strfry); relay-policy
healthcheck; strfry depends on relay-policy healthy
- `infrastructure/ops.sh` — adds relay:logs, relay:restart, relay:status commands
- `artifacts/api-server/src/routes/index.ts` — registers relayRouter
## Operator setup required on VPS
mkdir -p /data/strfry && chmod 700 /data/strfry
echo "RELAY_API_URL=https://alexanderwhitestone.com" >> /opt/timmy-node/.env
echo "RELAY_POLICY_SECRET=$(openssl rand -hex 32)" >> /opt/timmy-node/.env
# Also set RELAY_POLICY_SECRET in Replit secrets for API server
## Notes
- TypeScript: 0 errors (API server + relay-policy sidecar both compile clean)
- POST /api/relay/policy smoke test: correct bootstrap reject response
