🪢 SZL Holdings Data Lake (szl-lake)

A public, signed, diligence-defensible corpus of governance provenance. Every governed action in the SZL substrate emits an ECDSA P-256 DSSE-signed Khipu receipt onto a hash-linked Merkle DAG. This dataset aggregates those receipts together with formal-verification doctrine snapshots, the Zenodo paper record, SBOM pointers, and compliance attestations so a reviewer can verify the claims end-to-end.

Doctrine v11 LOCKED · 749 declarations / 14 unique axioms / 163 tracked sorries · Λ = Conjecture 1 (open, not a theorem).

Viewer contract

The Dataset Viewer intentionally exposes only khipu/*_receipts.parquet as the default receipts configuration. Those files share one fixed schema. The lake's other JSON, NDJSON, evidence, doctrine, and manifest files remain available by path, but they are heterogeneous artifacts and are not coerced into one false table.

The three byte-identical empty receipt chains are valid fixed-schema Parquet placeholders, not duplicated observations. They are retained for stable per-organ paths, contribute zero rows to the viewer, and are recorded in khipu/EMPTY_CHAIN_MANIFEST.json with their hashes and row counts.

Receipt schema (khipu/*.parquet)

No PII. Receipts carry only hashes, axis scores, organ/kind, doctrine numbers, and timestamps. A PII scan (email/SSN/phone patterns) ran clean before publication.

Read it

from datasets import load_dataset

receipts = load_dataset("SZLHOLDINGS/szl-lake", "receipts")
print(receipts["train"])

Or read one Parquet artifact directly:

import pyarrow.parquet as pq

table = pq.read_table(
    "hf://datasets/SZLHOLDINGS/szl-lake/khipu/amaru_receipts.parquet"
)
print(table.to_pandas().head())

How to verify a receipt with cosign

Each receipt is signed with an ECDSA P-256 key (keyid: szlholdings-cosign, or per-organ keys under keys/).

curl -sL https://huggingface.co/datasets/SZLHOLDINGS/szl-lake/resolve/main/keys/org-cosign.pub -o cosign.pub
cosign verify-blob --key cosign.pub --signature <dsse_sig> <receipt-payload>

Per-organ fingerprints (SHA-256 of the public key) are pinned in keys/MANIFEST.json and doctrine/v11_snapshot_20260602.json.

Honesty notes (diligence-defensible)

• —`lake build` status: current szl-holdings/lutar-lean@3f3ad80d passed both the Lake build and Lean kernel check. Those current-main checks are separate from this dataset's locked Doctrine v11 snapshot: receipts remain pinned to kernel commit c7c0ba17 and the 749/14/163 baseline in doctrine/v11_snapshot_20260602.json; additive experimental declarations are not silently promoted into that locked baseline.
• —Empty chains are shown as empty. Three organ chains have no receipts yet; their Parquet files are valid but empty rather than padded with synthetic data.
• —SBOMs and trajectories are pointer manifests where the corpus has not yet been seeded; the schemas are published so consumers can build against them today.

Honesty (Doctrine v11): Λ unconditional uniqueness is Conjecture 1 (machine-checked false as stated), never a theorem; conditional uniqueness is Theorem U (axiom-free). Locked-proven formulas are exactly 8 {F1,F4,F7,F11,F12,F18,F19,F22}; experimental theorems are a separate CI-green tier; Khipu BFT safety is Conjecture 2. Trust never 100%.
