Implement the rest of NETWORKING-DESIGN.md (N2–N6) and eliminate every
`.c` file from the repo. clang remains only the LLVM-IR assembler; no C
is compiled anywhere.
Networking (selfhost/emit_net.ludic + parser/emit changes):
- N2 @Sync: per-model serialize/apply + by-kind dispatchers; POD-scalar
compile error and empty-participation warning; selective replication.
- N3 @Owned: @L_owner array + owner/set_owner/is_owner; owners snapshot.
- N4 @ToServer/@ToClients remote events: framed net_send + net_pump re-emit.
- N5 @Server/@Predicted role guards + drivable sim (tick_fixed/tick_render,
entry-owns-the-loop).
- Built-in loopback transport so multiplayer runs with zero foreign code;
extern fn net_send/net_poll still overrides it for a real socket.
- N6 blessed runtime (examples/net_rt.ludic) + end-to-end demo (net_demo).
- Fix: llty("entity") is now i32 (entities are i32 handles), so let e = self().
C elimination:
- Networking + foreign-mod-ABI tests rewritten as self-contained pure-Ludic
programs (examples/net_*, world_*, mod_events, scoped); tests/ removed.
- Reflection ABI exposed to Ludic as world_* builtins (Ludic-to-Ludic modding).
- Formatter rewritten C→Ludic: tools/ludic-tools/fmt.ludic.
- Language server rewritten C→Ludic: tools/ludic-tools/lsp.ludic (lexer, index
parser, cross-file workspace resolver, JSON, all LSP handlers).
- Obsolete migrate_*.c codemods deleted; ludic_syntax.h kept as vocabulary data.
Suites: ./test.sh 44/44, ./tools/test-tools.sh 28/28 (LSP 42/42), fixpoint holds.

# net_rt.ludic — a blessed, server-authoritative replication runtime (NETWORKING
|
|
# N6). It ties the language's networking primitives together into a batteries-
|
|
# included default, the way tests/mod_c/mod.c proved the event ABI — but written
|
|
# in Ludic, over the built-in transport, with no foreign code.
|
|
#
|
|
# This is LIBRARY POLICY, not the language (NETWORKING-DESIGN §10, §12): it picks
|
|
# server-authoritative state replication. The seams stay open — swap this for
|
|
# lockstep+rollback (world_save + tick_fixed on misprediction) or your own.
|
|
#
|
|
# Frame layout on the wire: [i32 entity id][synced field bytes]. The authority
|
|
# calls rt_replicate(e) per entity each tick; a peer calls rt_receive() to drain
|
|
# inbound snapshots and apply them. serialize/apply are the compiler-generated
|
|
# @Sync codecs; net_send/net_poll are the transport seam (built-in loopback here,
|
|
# a real socket when a program binds `extern fn net_send/net_poll`).
|
|
|
|
# The authority ships one entity's authoritative synced state to peers.
|
|
fn rt_replicate(e: int) -> void {

|
|
let n = serialize(e, offset(w, 4)) # synced fields after it
|
|
net_send(0, w, 4 + n)
|
|
}
|
|
|
|
# A peer drains every inbound snapshot and applies it to the named entity. One
|
|
# datagram per poll (the transport is datagram-preserving), so loop until empty.
