# QA: apr run Falsification Suite
Popperian falsification tests for the `apr run` command with full matrix support
(PMAT-QA-RUST-001 + PMAT-QA-MATRIX-001).
Uses the Same-Model Comparison Protocol (PMAT-SHOWCASE-METHODOLOGY-001):
- **Class A (Quantized):** GGUF Q4_K_M vs APR Q4_K (converted from same GGUF)
- **Class B (Full Precision):** SafeTensors F32 vs APR F32 (converted from same SafeTensors)
## Run
```bash
cargo run --example qa_run
cargo run --example qa_run -- --model path/to/model.gguf
cargo run --example qa_run -- --gpu
```
## Source
```rust,ignore
