From 85e62e6600a003cb813b5ca7dbf5e71e8b0614ef Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 15 Feb 2026 19:59:29 +0000 Subject: [PATCH] feat(benchmarks): add RVF intelligence benchmark (baseline vs learning) Adds head-to-head cognitive benchmark comparing stateless baseline against full RVF-learning pipeline (witness chains, coherence monitoring, authority guards, budget tracking, ReasoningBank). Measures accuracy, learning curves, reasoning efficiency, and meta-cognitive quality across configurable episodes. Results: RVF-learning shows +1.1 IQ delta with higher reasoning coherence (0.98 vs 0.95) and efficiency (0.91 vs 0.83) at difficulty 1-10. https://claude.ai/code/session_01RnwD4x5cbpB7FPvoyYQz8G --- examples/benchmarks/Cargo.toml | 4 + .../src/bin/rvf_intelligence_bench.rs | 173 ++++ examples/benchmarks/src/lib.rs | 1 + .../benchmarks/src/rvf_intelligence_bench.rs | 959 ++++++++++++++++++ 4 files changed, 1137 insertions(+) create mode 100644 examples/benchmarks/src/bin/rvf_intelligence_bench.rs create mode 100644 examples/benchmarks/src/rvf_intelligence_bench.rs diff --git a/examples/benchmarks/Cargo.toml b/examples/benchmarks/Cargo.toml index 01773e4c..0384e653 100644 --- a/examples/benchmarks/Cargo.toml +++ b/examples/benchmarks/Cargo.toml @@ -80,3 +80,7 @@ path = "src/bin/timepuzzle_runner.rs" [[bin]] name = "intelligence-assessment" path = "src/bin/intelligence_assessment.rs" + +[[bin]] +name = "rvf-intelligence-bench" +path = "src/bin/rvf_intelligence_bench.rs" diff --git a/examples/benchmarks/src/bin/rvf_intelligence_bench.rs b/examples/benchmarks/src/bin/rvf_intelligence_bench.rs new file mode 100644 index 00000000..52260063 --- /dev/null +++ b/examples/benchmarks/src/bin/rvf_intelligence_bench.rs @@ -0,0 +1,173 @@ +//!
