SZL test-results — anatomy alive-harness sink

Public, DSSE-signed results sink for the SZL anatomy alive-harness. This dataset was retired earlier in 2026 and stood back up on 2026-07-21 as the harness's fail-closed publishing target — restoring the public proof loop behind every "harness verified" claim in the estate.

What a run is

anatomy_alive_v6.py (in this repo) drives live assertions across the whole substrate — organ liveness, live formula-gate executions, the yuyay_v3 13-axis schema, Wire D traceparent propagation, the Hatun MCP gateway and its real ECDSA-P256 DSSE signer, anatomy-map doctrine invariants on three surfaces, and the Khipu receipt chain. Every assertion is a real HTTP probe or a real cryptographic verification at the recorded timestamp; counts are derived from the assertion records, never hand-typed.

Files

File	Meaning
harness_runs.jsonl	One line per published run: {run, dsse} — the compact run record plus its DSSE envelope
runs/<stamp>.evidence.json	Full per-assertion evidence for that run
runs/<stamp>.dsse.json	The DSSE envelope alone
anatomy_alive_v6.py	The harness itself (reproduce a run yourself)
publish_harness_run.py	The fail-closed publisher (verify-then-publish)
PUBKEY_szlholdings-ec-p256.pem	Copy of the committed org public key

Trust model (honest, binding)

• Run records are DSSE (PAE v1) signed by the live Hatun MCP gateway (dsse_sign tool, ECDSA-P256, keyid szlholdings-ec-p256). The signing key never touches the publisher.
• The publisher is fail-closed: it verifies the gateway's signature against the committed public key (hatun-mcp/PUBKEY_szlholdings-ec-p256.pem) before any upload, and re-verifies after upload. Nothing unsigned or unverified is ever published. A gateway in placeholder-signer mode aborts the publish.
• run.evidence_sha256 binds each signed record to its full evidence file.
• A signature proves the record was signed by the holder of the org key at publish time — it does not upgrade any doctrine claim. Λ remains Conjecture 1; locked-proven formulas remain exactly 8.

Verify a record yourself

import base64, json
from cryptography.hazmat.primitives import hashes, serialization
from cryptography.hazmat.primitives.asymmetric import ec

rec = json.loads(open("harness_runs.jsonl").readlines()[-1])
env = rec["dsse"]
payload = base64.b64decode(env["payload"])
pae = b"DSSEv1 %d %s %d %s" % (len(env["payloadType"].encode()),
      env["payloadType"].encode(), len(payload), payload)
pub = serialization.load_pem_public_key(open("PUBKEY_szlholdings-ec-p256.pem","rb").read())
pub.verify(base64.b64decode(env["signatures"][0]["sig"]), pae, ec.ECDSA(hashes.SHA256()))
print("OK:", json.loads(payload))

Lineage

Predecessor harness: run_anatomy_alive.py (.github/coordination/anatomy_alive/, 2026-05-30 closeout — L1/L2/L5/L6 PASS, L3/L4 STAGED, L7 NOT-YET-WIRED). The v6 harness replaces STAGED labels with live probes of the now-running substrate.
