Stand up the WebSocket live-broadcast server inside the Processor process: - src/live/server.ts: createLiveServer factory with start/stop lifecycle, per-connection LiveConnection type, sendOutbound helper with back-pressure guard, 30s frame-level heartbeat via ws ping/pong, pluggable onMessage handler (stub returns error/not-implemented until 1.5.2/1.5.3). - src/live/protocol.ts: zod schemas for inbound subscribe/unsubscribe messages, all outbound types (subscribed/unsubscribed/position/error), WsCloseCodes. - src/shared/types.ts: extracted Metrics interface so src/live/ can import it without crossing the enforced src/live/ ↔ src/core/ ESLint boundary. - src/core/types.ts: re-exports Metrics from shared/types to keep Phase 1 call sites unchanged. - src/config/load.ts: LIVE_WS_PORT, LIVE_WS_HOST, LIVE_WS_PING_INTERVAL_MS, LIVE_WS_DRAIN_TIMEOUT_MS, LIVE_WS_BACKPRESSURE_THRESHOLD_BYTES, DIRECTUS_BASE_URL, DIRECTUS_AUTH_TIMEOUT_MS, DIRECTUS_AUTHZ_TIMEOUT_MS, LIVE_BROADCAST_GROUP_PREFIX, LIVE_BROADCAST_BATCH_SIZE, LIVE_BROADCAST_BATCH_BLOCK_MS, LIVE_DEVICE_EVENT_REFRESH_MS. - src/observability/metrics.ts: Phase 1.5 metrics inventory (connections, inbound/outbound counters, auth/authz histograms, subscription gauge, broadcast counters + lag histogram, snapshot histograms, device-event map). - src/main.ts: wires the live server alongside the durable-write consumer; shutdown order: live server → consumer → metrics → Redis → Postgres. - eslint.config.js: import/no-restricted-paths zones for src/live/ ↔ src/core/. - test/live-server.test.ts: 7 unit tests covering connect, ping, protocol violation, valid message dispatch, connections gauge, and stop() drain.
