1. // ws-event-order-load.mjs — 039_http1_ws_client's events must arrive in the order they
2. // happened under load, too (2026-10-02). Two orderings were measured broken there only
3. // when threads get preempted: the client's `open` before the server's `connect` (fixed by
4. // the loop's stamp order, plugin_api.zig `head_stamp_fn`), and the client's `close`
5. // before the server's (the server queued its `close` after writing the echo: 18-25 of
6. // 100 runs, 10 copies on 3 CPUs under HL_GC_STRESS=1). No in-process trick stalls a
7. // plugin thread between a write and a queue, so this is the loaded repeat: the fixture
8. // compiled --native, LANES copies at once pinned to 2 CPUs, RUNS rounds (master before the
9. // close fix: 2-6 of the 192 out of order, 5 tries of 5; ~8 s).
