# Embodied silicon carbon TCO audit

## Description
Audits embodied carbon in GPU manufacturing (Scope 3) amortized per 1 billion inference tokens.

## Category
`pricing`

## Tags
`pricing`, `embodied-carbon`, `scope3`, `silicon`, `tco`

## When to Use
Audit full lifecycle carbon accounting for on-premise clusters versus cloud inference providers.

## Operational Limitations
Calculates amortized Scope 3 grams per 1M tokens based on device lifetime and volume; does not audit fabs.

## 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.

## What the checker recomputes

The original threshold checks still apply:

- `amortized_embodied_g_per_m_tokens` must not be > `max_allowed_g`.

Every other declared field is type-checked. A negative value is rejected except for deltas, drifts, and gains. A type check does not, by itself, prove the measurement.

`population` and `observedAt` are required. The bundled examples are synthetic fixtures, not market measurements.

```bash
python3 scripts/check.py examples/synthetic.json
python3 scripts/check.py examples/contradiction.json
python3 scripts/check.py examples/broken.json
```

Exit 0 is a pass, exit 1 is a review, and exit 2 is invalid input. A pass does not certify a provider, a regulation, a release, or a price.
