+**The server half (done, 2026-10-05)**: `npro_h1::server::Server`, one
+connection's transactions.  `rx` takes at most one thing per call, a
+request's head, a piece of its body borrowed from the input, or the body's
+end, and holds what it did not take, so pipelined requests wait and body
+bytes that came with a head are never lost.  `respond` composes C's status
+line and headers, `tx` writes what the connection owes and then pulls the
+payload from a `TxSource`, and `complete` is C's
+`lws_http_transaction_completed()`.  C's checks between head and app run
+in C's order (400 for both framings or two Hosts, 417, 501, 400 for a bad
+or second Content-Length, 413), a refusal is C's status page and a
+shutdown, an answer short of its length or without one shuts down, and
+keep-alive follows the version and `Connection`.  A request with neither
+Content-Length nor Transfer-Encoding has no body, as C now has it
+(`h1-post-no-length`).  `tests/h1_server_replay.rs` replays 19 of C's
+server transcripts byte for byte with C's `sansio-uri` app: the `h1-uri-*`
+and `h1-reqline-*` ones, `h1-header-past-limit`, `h1-post-no-length`,
+`h1-short-answer` and `h1-body-done`.
+
+Not yet: the connection machines of phase 1b are not driven by it, `Expect:
+100-continue` is accepted but no 100 is sent, a fallback role is a
+shutdown, and there is no fuzz target for it.  The client half comes
+next.
