Wickra Verify — R


Part of the Wickra ecosystem — for R. install.packages("wickraverify", repos = "https://wickra-lib.r-universe.dev") — over the C ABI via .Call, prebuilt library fetched on install.

Recompute a claimed backtest report with the deterministic Wickra engine and confirm or refute it, from R over the Wickra C ABI hub (.Call). A doctored claimed_report cannot pass, because verification recomputes rather than trusting the supplied numbers.

Install

From r-universe:

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

The package's configure downloads the prebuilt C ABI library for this exact version from the GitHub release and bundles it, so an ordinary install needs nothing but a C toolchain (Rtools on Windows) for the thin .Call glue layer. To build against a local checkout instead, point it at the header and library with the environment variables below.

The package compiles a small C shim against the wickra-verify C ABI. Point it at the C ABI header and shared library via environment variables:

cargo build -p wickra-verify-c            # build the native C ABI library
export WKVERIFY_INC=/path/to/bindings/c/include
export WKVERIFY_LIB=/path/to/target/release
R CMD INSTALL bindings/r

At run time the loader must find the shared library (LD_LIBRARY_PATH / DYLD_LIBRARY_PATH, or PATH on Windows).

Quick start

Everything goes through a verifier handle driven by JSON commands — the same command protocol every Wickra binding shares.

library(wickraverify)

verifier <- wkverify_new()

claim <- paste0(
  '{"strategy":', strategy_spec, ',',              # a wickra-backtest StrategySpec
  '"dataset_ref":{"kind":"inline","data":', data, '},',
  '"claimed_report":', report, '}'                 # the report being checked (untrusted)
)
verdict <- wkverify_command(verifier, paste0('{"cmd":"verify","claim":', claim, '}'))
cat(verdict)  # the full Verdict as JSON

Commands

cmd Payload Response
verify {claim, data?} the full Verdict
explain {verdict} {ok:true,text:...}
canonicalize {value} {ok:true,canonical:...}
version — {version:...,engine_version:...}

For files-kind claims, supply the candle data under a top-level data key; inline claims carry their data already.

Domain errors (a bad claim, an unknown command) come back in-band as {ok:false,error:...}; only null/UTF-8/panic conditions raise an R error.

Benchmark

Every binding forwards to the same data-driven Rust core, so what this one adds is the call overhead of R's native .Call interface over the C ABI, not a different result. The core's throughput is measured by the repository's benchmark suite and the nightly bench.yml run; the numbers, the machine and how to reproduce them are in the repository BENCHMARKS.md.

Documentation

The full guide, the spec reference and the API documentation live in the main repository and the documentation site:

Wickra Verify ships native bindings for Python, Node.js, WASM and Rust, plus a C ABI hub that any C-capable language (C, C++, C#, Go, Java, R) links against — all forwarding to the same data-driven, unsafe-forbidden Rust core.

Disclaimer

wickra-verify is research and engineering tooling, not financial advice. A verdict attests only that a claimed report is (or is not) the deterministic result of a given strategy over given data — it makes no claim about the quality, profitability or future performance of any strategy, nor about whether the data itself is genuine. Trading carries risk; you are responsible for your own decisions. wickra-verify is free software you run yourself: no hosted service, no data collection, no warranty.
