Governed Receipts Bench · a conformance corpus for the governed-receipt spec

A small benchmark corpus of governance decision receipts for the open governed-receipt-spec. Every receipt here has a known expected outcome under the spec's dependency-free offline verifier: the valid/ receipts must PASS, the invalid/ receipts must FAIL. Use it to test a verifier implementation, to see what a real SZL receipt looks like, or to check your own receipts against the same rules.

Built and maintained by SZL Holdings. Apache-2.0.

Honesty first. The valid/ receipts are real records drawn factually from SZL's public receipt datasets — nothing is fabricated. The invalid/ receipts are clearly-labeled tampered derivatives of a real receipt, included only so the verifier's failure paths are testable. No metric here is invented; where a value was not measured (e.g. energy joules) it is honestly null / UNAVAILABLE.

What a governed receipt is

A governed inference receipt is the small, replayable, hash-chained record a governed AI runtime emits for one governed action (e.g. an inference): what it decided, the Λ governance-floor status, whether energy was actually measured, and a signed DSSE envelope that lets anyone re-check it offline.

A receipt is explicitly NOT a zero-knowledge proof and NOT a proof of computation — it is a signed, tamper-evident audit record of a governance decision and its bound content hashes. That is the "receipt tier" of trust (cheaper than TEE or zkML; deployable today). See the spec for the full framing.

Layout

bench.jsonl          # one row per case: file, category, expected_result, source, note
valid/               # real receipts — MUST verify PASS
  a11oy-khipu-chain.json      # 5-receipt signed hash chain (seq 0->4)
  a11oy-khipu-genesis.json    # single signed genesis receipt (seq 0, prev = 64 zeros)
  lake-inference-receipt.json # decision=allow + measured-or-null energy in the clear
  readiness-audit-receipt.json# unsigned envelope, content bound by payloadSha256
  daily-activity-receipt.json # HMAC-stub daily activity receipt
invalid/             # LABELED tampered derivatives — MUST verify FAIL
  tampered-payload.json       # a payload byte flipped -> DSSE PAE content-hash mismatch
  broken-chain.json           # prev rewritten -> hash-chain link breaks

bench.jsonl is the machine-readable manifest (the dataset viewer renders it): each row carries file, category (valid/invalid), expected_result (PASS/FAIL), the source_dataset it was drawn from, n_receipts, and a note.

Provenance of the valid/ receipts (real data)

File	Source dataset	Shows
valid/a11oy-khipu-chain.json	SZLHOLDINGS/a11oy-verifiable-corpus (receipts/)	a 5-receipt signed DSSE hash chain (seq 0→4)
valid/a11oy-khipu-genesis.json	SZLHOLDINGS/a11oy-verifiable-corpus (receipts/)	a single signed genesis receipt (seq 0, prev = 64 zeros)
valid/lake-inference-receipt.json	SZLHOLDINGS/a11oy-verifiable-corpus (lake/)	decision + measured-or-null energy in the clear
valid/readiness-audit-receipt.json	SZLHOLDINGS/readiness-runs	unsigned envelope with payloadSha256
valid/daily-activity-receipt.json	SZLHOLDINGS/szl-evidence	HMAC-stub daily activity receipt

The two invalid/ files are byte-level tampers of a11oy-khipu-chain.json, included purely to exercise the verifier's failure detection — they are not real records.

How to verify (one command, zero dependencies)

The verifier is Python 3 standard library only — no third-party packages, no network.

# 1. get this bench corpus
git clone https://huggingface.co/datasets/SZLHOLDINGS/governed-receipts-bench
# 2. get the spec + verifier
git clone https://github.com/szl-holdings/governed-receipt-spec
cd governed-receipt-spec

# 3. the real receipts PASS ...
python verify.py ../governed-receipts-bench/valid/*.json          # -> OVERALL: PASS

# 4. ... and the tampered ones FAIL
python verify.py ../governed-receipts-bench/invalid/tampered-payload.json  # -> OVERALL: FAIL (PAE sha256 mismatch)
python verify.py ../governed-receipts-bench/invalid/broken-chain.json      # -> OVERALL: FAIL (chain link break)

Or paste any receipt into the live verifier Space: SZLHOLDINGS/governed-receipt-verifier.

For each receipt the verifier: (1) validates the decoded decision object against the JSON Schema, (2) recomputes the content hash (sha256(DSSE PAE) == _pae_sha256 for signed receipts, or sha256(payload) == payloadSha256 for readiness receipts), (3) checks the prev-hash chain (prev == previous.digest, contiguous seq, genesis is 64 zeros), and (4) structurally checks the DSSE envelope.

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 = exactly 8 {F1,F4,F7,F11,F12,F18,F19,F22}; ~185 experimental theorems are a separate CI-green tier; Khipu BFT safety = Conjecture 2. Trust never 100%.
