Szl Holdings Python Packages

szl-receipt-dsse

Shared signed-receipt library — DSSE/ECDSA-P256, cosign-compatible, UNSIGNED-honest fallback. The one signing primitive every SZL component shares.

szl-engine-bench

Honest inference-engine benchmark harness: TTFT/throughput percentiles for vLLM, SGLang, llama.cpp, MLX, TGI, Transformers. Fairness gates, hash-chained receipts. BLOCKED, never fabricated. Stdlib only. Apache-2.0.

szl-guardrail-receipt

Wrap any LLM guardrail (Llama-Guard / NeMo / guardrails-ai / your callable) and emit a signed, hash-chained DSSE decision receipt — aligned with governed-receipt-spec. UNSIGNED-honest fallback; never fabricates a signature, energy joule, or a Λ 'proven'.

szl-receipts

Tamper-evident, hash-chained receipts for every LiteLLM request — standalone distribution of szl-receipts + the SZL evidence plugin

szl-evidence-litellm

Tamper-evident, hash-chained receipts for every LiteLLM request — standalone distribution of szl-receipts + the SZL evidence plugin

szl-energy-attest

Attestable energy receipts for governed compute — MEASURED-NVML joules (or honest UNAVAILABLE null), cheapest-watt placement, hash-chained signable receipts. Vendors szl_energy_core. Λ = Conjecture 1 (advisory) · never fabricates a joule · Mirrors HF SZLHOLDINGS/szl-energy-attest · Apache-2.0.

vsp-otel

SZL OTLP collector, signed-span exporter and Helm package. Restored source owner; runtime and forwarding acceptance verified separately.

szl-nemo

SOFTWARE/SURROGATE: doctrine rule_check for recipe conformance. Not Nemotron, not an LLM, not a CUDA kernel. joblib quarantined.

khipu-x1

KHIPU-X1 — FPGA-first governed LLM accelerator software reference (SOFTWARE_EMULATED; no hardware claimed). Doctrine v11.

szl-calibration

Calibration Intelligence Plane — exact calibration metrics (ECE/MCE/Brier/NLL/AUROC), UNSIGNED_HONEST hash-chained receipts, fail-closed safetensors weight gates, FastAPI + Prometheus surface. Doctrine v11. SOFTWARE honesty. Apache-2.0.

szl-ci-witness

CI as witness: every workflow run appends a hash-chained receipt (repo, commit, run id, conclusion, test counts) to a verifiable chain. Regressions and fixes are detected from the chain, not from dashboards. Verify anyone's chain offline. Fail-closed.

szl-eclipse

Who verifies the verifier: mutation-testing for receipt verifiers. Ten attack classes (metric tamper, reorder, lane/key rename, truncation, type confusion, duplicate injection) against a golden chain; reports verifier sensitivity with a receipt. BLIND-SPOT state names what slipped. Fail-closed.

szl-crosscheck

Cross-implementation verification: two independent harnesses' receipt chains in, CONSISTENT/DIVERGENT/INCOMPARABLE out, with a dual-signed master receipt. Settles which bench to trust — or proves they agree. Fail-closed.

szl-quant-bench

Honest quantization quality-curve bench: uniform absmax quantization, cosine/KL/top-1 degradation vs bit-width, hash-chained receipts. Real logits in, measured curves out — BLOCKED, never fabricated. Stdlib only. Apache-2.0.
