Release notes: httpd M1.5 SSE runtime (m15-sse-runtime)

Branch: cursor/httpd-plan-continue

Summary

Live build/li-httpd now enforces limits.stream_idle_timeout during chunked SSE proxy relay: inter-chunk stalls return 504 Gateway Timeout and close the upstream connection. Idle detection runs on a periodic tick (not only on epoll events), and chunk timestamps update for chunked upstream bodies relayed to the client.

Changes

  • runtime/li_rt_net.c — SSE chunk timestamps on body relay; idle tick + bounded epoll in C and Li proxy loops; upstream cancel on stall
  • packages/li-net-httpd/src/lib.li — httpd_upstream_proxy_epoll_loop calls SSE idle tick + timed epoll wait
  • std/runtime/seam.li — exports for SSE idle tick and timed epoll wait
  • packages/li-net-httpd/examples/sse_idle.toml — short idle timeout for gate smoke
  • scripts/test-m15-sse-runtime.sh — live SSE relay + stall cancel gate
  • scripts/httpd-plan-gates.sh — wire m15-sse-runtime smoke
