Arcadia MCP

This score was committed to a single Merkle root along with every other score we published that day. The root is signed, published, and archivable by anyone — so if we changed this number tomorrow and said it had always been this, the commitment would contradict us. It proves what we published, not that the score is right.

Verify this yourself

# 1. The proof: record, leaf, leaf_preimage, proof (sibling digests)
curl -s "https://satohub.ai/api/verify/arcadia-mcp/proof?date=2026-10-15"
# 2. The roots file, fetched separately; take the root for 2026-10-15
curl -s https://satohub.ai/.well-known/sato-score-roots.json
# 3. leaf = SHA-256(leaf_preimage). For each sibling s:
#    leaf = SHA-256("satohub-score-node/v1" || min(leaf,s) || max(leaf,s))
#    The result must equal the root from step 2.
# 4. Check that root's signature against https://satohub.ai/.well-known/jwks.json

No command-line tool is published for score proofs yet; the steps above are the whole check. Compare against the published roots file, not against the root in the proof response — checking a proof only against a root served in the same reply proves nothing. Raw proof: /api/verify/arcadia-mcp/proof. Method: the house rules.
