# FP4 E2M1 microscaling audit

## Description
Audits OCP Microscaling Formats (MXFP4 / E2M1) block scaling factors and perplexity degradation delta.

## Category
`serving`

## Tags
`serving`, `fp4`, `e2m1`, `microscaling`, `perplexity`

## When to Use
Audit hardware-accelerated MXFP4 formats to ensure perplexity delta over FP8 remains tightly bounded.

## Operational Limitations
Verifies reported perplexity differentials on standard evaluation benchmarks; does not perform forward passes.

## Verification Script
Run the deterministic verification checker:
```bash
python3 scripts/check.py examples/synthetic.json
```
Exit codes:
- `0`: Check passed and thresholds satisfied.
- `1`: Threshold breach or operational violation detected.
- `2`: Schema error or invalid usage.
