+# 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`](https://github.com/szl-holdings/hatun-mcp/blob/main/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

+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()))

+Successor to run_anatomy_alive.py (2026-05-30, 7-layer STAGED-PASS). The v6
+harness asserts against the LIVE substrate (no gh CLI dependency, no synthetic
+trace): every assertion is a real HTTP probe of a public surface or a real
+cryptographic verification. No STAGED label is used for anything that can be
+exercised live today; anything that cannot is reported NOT-LIVE with the reason.

+publish_harness_run.py — FAIL-CLOSED publisher for anatomy alive-harness runs.
+
+Pipeline (any failure aborts the publish — nothing unsigned or unverified is
+ever uploaded):
+  1. Read the evidence JSON produced by anatomy_alive_v6.py.
+  2. Build a compact run record (counts DERIVED from the assertion list —
+     recomputed here, not trusted from the summary fields).
+  3. Ask the live Hatun MCP gateway to DSSE-sign the record (tools/call
+     dsse_sign). The gateway signs with the org ECDSA-P256 key; a PLACEHOLDER
+     response aborts the publish.
+  4. Verify the returned envelope locally against the COMMITTED public key
+     (hatun-mcp/main/PUBKEY_szlholdings-ec-p256.pem) over DSSE PAE v1.
+  5. Append the signed record to harness_runs.jsonl in the public
+     SZLHOLDINGS/test-results dataset and upload evidence + envelope files.
+
+Usage: HF_TOKEN=... python3 publish_harness_run.py evidence.json
