Differential Testing Python Packages

franken-networkx

Memory-safe clean-room Rust reimplementation of NetworkX with deterministic graph semantics, differential conformance, and RaptorQ-backed durability.

fhe-oracle

FHE Oracle — adversarial precision testing for Fully Homomorphic Encryption. Open-source edition (AGPL-3.0).

liveness-primer

Primer for blast radius analysis and differential testing of dead code detectors and static analysis tools across pinned real-world projects

agent-budget-semantics

Differential testing of budget enforcement semantics across 11 AI agent frameworks. Same work, same tokens, 4 different telemetry values.

crondelta

Compare Python cron engines and library versions within a finite time window, with reproducible UTC differences and timezone-aware evidence.

falsifyai

Portable, content-addressed reliability evidence for LLM systems. Capture how a model behaves under perturbation; preserve, verify, and diff the evidence across model changes.

cleitonforge

Differential fuzzer for quantum compilers. Found the CommutativeCancellation soundness bug fixed in Qiskit 2.5.1.

tracebook-sim

Conformance testing, semantic diffing, and minimal reproducible failures for matching engines.

parquity

Find and reproduce semantic disagreements between Parquet engines.

etheno

Simplify Ethereum security analysis and testing

nodrift

Prove a refactor changed nothing — by replaying your tests' real inputs against both versions.

hcp-align

Exact alignment oracle for generating references, verifying JSON/PAF/SAM records, and explaining backend disagreements.

docx-parse-eval

Differential-testing harness for .docx parsers: OOXML reference extraction vs. Docling output, TEDS table metrics, snapshot drift

ishvacerto

Prove AI-written code, refute it with the exact failing input, or honestly abstain. Never guesses. Runs locally.

tracebook-conformance

Conformance testing, semantic diffing, and minimal reproducible failures for matching engines.
