Cryptographic
Evidence Bundles

Every SynthLabTech generation produces a signed evidence bundle. Every job sealed. Every output provable. No exceptions, regardless of engine or plan.

What's in Every Bundle

Every generation — regardless of engine or plan — includes the same evidence categories. None are optional. None can be suppressed.

Sealed Job Spec

The Contract K commitment that defines exactly what was generated — engine selection, schema, constraints, seed, and output format. The single source of truth for the run.

Run Log

Execution telemetry — rows generated, timing breakdowns, engine version, configuration hashes, and runtime environment details. Everything needed to understand what happened during the run.

Quality Reports

Statistical fidelity, constraint satisfaction, and privacy risk assessments. Distribution accuracy, correlation preservation, marginal fidelity per column, k-anonymity measurements, and re-identification risk analysis.

Cryptographic Seal

An evidence seal that binds every artifact under tamper-evident cryptographic commitment. Third parties can verify the entire bundle independently — without access to your production data or our infrastructure.

Determinism Guarantee

SynthLabTech uses BLAKE3 hashing, seed-reproducible cryptographic RNG, and tenant-isolated compute to guarantee that any generation can be reproduced exactly. Given the same Contract K and seed, output is bit-for-bit identical across any environment.

Seed-Reproducible RNG
Cryptographically-strong, seed-reproducible random number generation — same seed produces identical sequence across any hardware, OS, or runtime environment.
BLAKE3 Throughout
Every artifact, every file, every intermediate output is hashed with BLAKE3. The final seal binds them all.
Tenant Isolation
Compute environment is isolated per tenant. No shared state can contaminate determinism across jobs.
Zero-Trust API
Every API call is authenticated and logged. The run manifest records the exact API version and configuration hash.
Determinism verification
Contract K hash:
blake3("c0f8...a3b2")
Expected output:
blake3("7d4e...91fc")
Actual output:
blake3("7d4e...91fc")
✓ MATCH — determinism certificate issued
Trust your synthetic data
Any third party can verify the bundle from the seal alone
Evidence bundles are machine-readable and auditor-ready
No access to production data required for verification
Bundle integrity is independent of SynthLabTech infrastructure

Every job sealed. Every output provable.
