The httpz shape, one worker, handlers inline over the std.event Loop: nonblocking accept, per-connection state machine (reading -> writing -> keepalive/close) with incremental parsing (request line, headers, Content-Length body), partial-write continuation via on-demand write interest, pipelined-request draining, and timeouts as EVICTION — request-delivery and keepalive-idle deadlines on the monotonic clock, checked after I/O each tick. Keep-alive is the HTTP/1.1 default; Connection header, HTTP/1.0, or the per-connection request_count cap turn it off. Config mirrors httpz: port/backlog/max_conn/read_buf_cap/ timeout_request_ms/timeout_keepalive_ms/request_count. API: Server.init(cfg, handler) + tick(max_wait_ms); run() is the forever-tick loop. tick makes the server drivable single-threaded — examples/1633 runs a live server and its client sockets in ONE thread, pinning: GET with keep-alive, actual connection reuse, the request cap answering Connection: close then EOF, POST body echo, 404 routing, and a half-header client evicted at the request deadline while a healthy client keeps being served. Verified under sx run AND sx build. Connection slots and read buffers are reused across connections (httpz's min_conn/buffer-pool spirit); response buffers are allocated per response and freed on completion. Serialization happens while request views are valid, the served bytes are compacted, and only then does sending start — write_more's pipelining check must see only the remainder. The std.sx barrel carries http; .ir snapshot regen is the usual mechanical renumbering. S7b adds worker counts + the handler thread pool (needs C2/S6); the epoll backend activates with the linux target (S4/S7c).
