R

Compiled C glue over the ABI, called with .Call. configure downloads the prebuilt library matching the package version and bundles it, so an ordinary install needs nothing extra.

install.packages("wickrabenchmark", repos = "https://wickra-lib.r-universe.dev")

library(wickrabenchmark)

bench <- wkbench_new()
response <- wkbench_command(bench, paste0(
  '{"cmd":"run_case","case":', case_json, ',"data":', candles_json, '}'
))

cat(wkbench_version(), "\n")
cat(response, "\n")

The command surface

Every binding exposes the same four commands and returns the core's canonical JSON string verbatim. That is what makes byte equality the cross-language check.

cmd	Payload	Response
run_case	{case, data}	a CaseResult — passed, hash_match, hash, recomputed
run_suite	{suite, datasets}	a SuiteReport — the results sorted by id, plus the tally
list_cases	{suite}	{"ids": [...]}, sorted
version	—	{"version": ..., "engine_version": ...}

A domain error — a malformed case, an unknown command — comes back in-band as {"ok":false,"error":...} rather than as an exception.

One committed example of every envelope lives in golden/commands/, with the exact response each must produce beside it in golden/expected/.
