Receipt Chain

HX-SDP. 100M vectors. A single H100 node. 100% exact recall.

The data-infrastructure counterpart to the Vlasov-6D physics receipt. Same cryptographic chain. Same verification tools. A workload that most enterprise buyers will care about first.

Run ID

Cryptographic Anchoring

Signature, hash, and manifest.

Signature

ML-DSA-65

FIPS 204. NIST Level 3.

Hash

SHA-256

FIPS 180-4. Manifest and every artifact.

Arithmetic

IEEE 754

Floating-point conformant. Deterministic across runs.

Manifest Hash

sha256:7e4b9c0a2d15...c49f (truncated for display)

Every receipt, every artifact, every aggregate is signed with ML-DSA-65 (FIPS 204) over an SHA-256 manifest. See the signature parameter policy for the full rationale.

Bounded scope

What this receipt claims. And what it does not.

In scope

  • +100M vector entries on the QTT-Native fp32 Production path. D=384, rank=32.
  • +100% Recall@10 measured against exact ground truth on 10K held-out probes.
  • +Single-client query stream. Latency percentiles over 2.9M queries.
  • +Single-node, single-H100 80GB. No multi-GPU sharding.

Not claimed by this receipt

  • Multi-tenant, multi-GPU, or cross-node deployment.
  • Concurrent client load above 64 simultaneous streams. See honest tradeoffs on /benchmarks.
  • Online single-insert throughput. This receipt is a batch-built index.
  • Workloads outside the published Atlas governance envelope.
