Spry for Evidence Warehouses

Generate Audit-Ready Markdown Notebooks

Execute and capture all outputs as structured evidence.
Perfect for compliance, research, and regulated environments where provenance matters.

What is an Evidence Warehouse?

An evidence warehouse is a collection of executable notebooks that generate and store proof of work.
Every query, transformation, and result is captured with timestamps, inputs, and outputs.This creates an immutable audit trail.

Provenance

Track where data came from, how it was transformed, and who ran the pipeline

Reproducibility

Rerun any notebook and get the same results. Critical for audits.

Compliance

Meet regulatory requirements with automatically generated evidence

How Spry Generates Evidence

1

Execute Cells

Spry runs each fenced block (SQL, Bash, JSON, etc.) and captures the output.

2

Capture Metadata

Timestamps, user info, execution duration, and environment details are stored alongside results.

3

Store as Artifacts

Results are saved as structured JSON, database records, or files. This creates a permanent evidence trail.

4

Version Everything

Markdown notebooks are versioned in Git, ensuring historical evidence is never lost.

Use Cases for Evidence Warehouses

1

Financial Compliance

Generate audit trails for financial calculations, risk assessments, and regulatory reporting

2

Clinical Research

Document data analysis pipelines for FDA submissions and peer review

3

AI Model Audits

Prove how training data was processed and what context was used for inference

4

Data Governance

Track data lineage and transformations for GDPR and privacy compliance

5

Quality Assurance

Generate test evidence showing what was checked and when

6

Research Reproducibility

Share analysis pipelines that anyone can rerun to verify results

Automated Audits

Spry notebooks can be scheduled to run automatically, generating fresh evidence on a regular cadence.

  • Daily compliance checks
  • Monthly report generation
  • Real-time monitoring evidence

Immutable Storage

Store evidence in append-only databases or immutable storage systems for maximum trust.

  • PostgreSQL with audit tables
  • S3 with versioning enabled
  • Blockchain-backed storage

Eliminate Drift Between Code and Docs

Traditional documentation goes stale the moment it is written. Spry notebooks execute, so documentation is always up-to-date with reality.

When auditors ask "How was this calculated?", you can show them the exact Markdown notebook that generated the evidence. They can rerun it themselves to verify.
