Release notes: serve_routed_once (M1 route-matched response)¶

Summary¶

Adds httpd_serve_routed_once: after loading routing.toml, handles one stub accept with a built-in GET /health request, match_route, and a static 200 (or 404/502 by action kind). Complements draft work on #84 (epoll perf) and #87 (M1 wave 1) without duplicating their serve loops.

Agent continuation¶

Read runtime/li_rt_httpd.c (li_rt_httpd_serve_routed_once, parse_http_request_line).
Run LI_REPO_ROOT=$PWD LI_ALLOW_OPEN_VC=1 ./li-tests/run_httpd_config.sh and ./li-tests/run_all.sh httpd.
Then: wire real tcp_recv + request buffer; integrate with httpd-m1-impl / httpd-m1-perf when those merge.
Blocked on: production reactor and proxy upstream (parallel PRs).

Changed¶

Path	Change
`runtime/li_rt_httpd.c`	`serve_routed_once`, minimal request-line parse, status responses
`packages/li-net-httpd/src/lib.li`	`httpd_serve_routed_once`
`li-tests/httpd/serve_routed_once.li`	Oracle test
`li-tests/run_httpd_config.sh`	Routed serve step

Not changed¶

li_rt_net.c stub fds (no real sockets).
Epoll/kqueue (cursor/httpd-m1-perf-54aa).
Generic static file server (cursor/httpd-m1-impl-54aa).
httpd_serve_once (unchanged blind 200).

Breaking¶

N/A

Security¶

Stub in-process only; fixed request line for M1 oracle.

Performance¶

N/A

Downstream¶

Rebase httpd-m1-impl / httpd-m1-perf onto this: replace built-in request with recv buffer when their net stack lands.
