szl-ouroboros

The cut, in one line: a loop with a budget, a gap, and a receipt.

Bounded-loop trace + loop-tax accounting. Not a model. No weights. Not the TypeScript product szl-holdings/ouroboros.

IS: a pure-Python, stdlib-only governance kernel. It rebuilds a run's attempt windows into labeled fields (modelMs MEASURED, overheadMs DERIVED, serializationTaxMs a counterfactual, never a realized saving). Public API: build_loop_trace, loop_tax, selfcheck.

IS NOT: trained weights. Not a CUDA bench. Hub model.joblib is QUARANTINED executable serialization — do not joblib.load it. When wall_ms is missing, overheadMs is UNAVAILABLE, never fabricated.

<!-- SZL-ATELIER-CUT:v1:START -->
## The cut

Agent frameworks retry until success. We tax the loop. Success that costs all remaining λ is a failure.

A runtime that cannot grind a gate into dust.

### Silhouette → leave → SZL

| Leader | Take, then tweak |
|---|---|
| Anthropic | Don't jailbreak yourself by persistence. |
| NVIDIA | Scheduler quota, but for authority. |
| Unsloth | No. |

Nobody else ships this combination. That is the point of a one-of-one.

## Intended use

Wrap agent retries.

## Limitations

- Kernel. Pair with governed-agent-bench.

LOOP_DOCTRINE = "bounded, terminating, receipt-closed". A budget violation is reported, never clamped. Λ is not touched here and stays Conjecture 1.
