Wired bend.lsp to lumbda's existing TCP primitives via wire.lsp
(length-prefixed S-exp framing, lifted from
ecdsa/lumbda/fleet/wire.lsp). The (bend …) macro now actually
dispatches: lumbda → tcp-connect → wire-send → wire-recv → result.
End-to-end on the 3090 (mock-worker as gpu-worker stand-in until
spawn-process-stdio lands in lumbda's core):
λ> (load "smoke-bend.lsp")
=== smoke-bend ===
1. cost estimator picks local for 3 inputs (cost too small): OK
2. worker available? #t
3. bend! (cuda-shake-fanout '("00" "01" "deadbeef") 32):
(#xb8d01df855... #x94da6280b2... #xfa094fa86e...)
All three hashes byte-identical to hashlib.shake_256.
Files added:
wire.lsp — 8-digit-LE length-prefixed S-exp framing
smoke-bend.lsp — minimal lumbda-side test
mock-worker.py — Python stand-in for gpu-worker.lsp until
spawn-process-stdio + flush-port primitives
land in lumbda's core
bug fix:
wire-recv had one missing close-paren; lumbda surfaced it as
'unclosed (' on load. Fixed in the same commit.
mock-worker.py accepts two request shapes since bend.lsp serializes
(quote (...)) for list literals while the portal format uses
(inputs ...). Tolerating both keeps the wire protocol bend-friendly.
Per-tier integration status:
Python tier — bend, wire, smoke-test all work ✓
C tier — needs: same Scheme files port directly; tcp-* exist;
spawn-process-stdio still missing for gpu-worker.lsp
asm tier — needs: tcp-* exist; spawn-process-stdio requires raw
fork + pipe + execve in asm; biggest delta vs Python
Open primitive gaps for full cross-tier bend:
spawn-process-stdio — for gpu-worker.lsp's daemon pool
flush-port — to push daemon stdin
(current-time-ms — exists in Python tier; needed in C/asm too)
Once those land, gpu-worker.lsp replaces mock-worker.py and bend
runs cross-tier-identical. The protocol & cost-estimator code in
bend.lsp + wire.lsp need no changes — they speak only the existing
tcp-* + read-from-string + write-to-string primitives every tier
already has.
