The previous attempt to ship a pretty summary via an (summary "...")
field inside the structured response broke on the asm (WAT) tier
because read-from-string isn't a primitive there — the demo
extraction fell through to the raw fallback and dumped the entire
escaped S-expression.
Two-part fix that works on all three tiers:
http-listener (gpu-worker.lsp:1103-1116) — POST response builder
now checks if the handle-request return value is a string and
ships it as the raw HTTP body in that case. S-expression returns
still go through write-to-string. One-line guard, no impact on
ping/health/cuda-shake-fanout/cuda-sim-ops-bin which all keep
returning structured S-exps.
handle-cuda-secp256k1-bench — returns the formatted summary
string directly instead of an (ok ... (summary ...)) wrapping.
Drops the now-redundant structured fields; every number lives
inside the human-readable text already. asm / c / python demo
just calls (display (bend!-call "(cuda-secp256k1-bench N)")) and
the formatted output panel renders identically on all tiers.
Demo simplified accordingly: three (display (bend!-call …)) calls
with newlines between, no read-from-string / assoc / pair? dance.
