a proof checker and model checker for minimal propositional logic
Continuous Integration system that automatically diagnoses, patches, and validates code issues using AI-powered analysis and formal verification.
Certified frame-first SAT middleware — decide structured regions (2-SAT · GF(2) parity · counting) before CDCL, and independently verify every verdict (model replay · DRAT). A research harness for where SAT hardness lives.
Provio will be a step-by-step math proof checker
Lean 4 verification portfolio: certified combinatorics, LRAT checking, toy robustness, and claim-boundary discipline.
A reproducible audit harness for mathematical LaTeX papers: deterministic scanner, schema-validated issue ledgers with mechanical quote verification, and a stage-gated final gate — driven by any MCP agent or the CLI.
Replayable Python protocol engine for checking time-bound future claims from canonical artifacts, with typed outcomes and audit trails.
Verifier-backed math reasoning lab for proof flaw localization, minimal repair, and RL-style evaluation.
Certified, composable map of impossibility claims with machine-checkable certificates and explicit trust rungs.
Certificate-backed verification for known Schur and van der Waerden values, with explicit trusted bases.
AI-assisted desktop app for auditing mathematical manuscripts, detecting proof issues, and generating reports.
