What is Stardive?

Stardive makes AI execution provable — not smarter, faster, or more automated.

Stardive is an execution & observation kernel that provides audit-grade truth for AI workflows. It captures execution provenance, stores artifacts immutably, and enables replay — without replacing your existing orchestration or agents.

Perfect for regulated industries (finance, healthcare, legal, government) that need defensible AI systems with complete audit trails.

Core Principle

Observation and provenance, not control.

We capture truth, we don't orchestrate.

---

Why Stardive?

Add ~10-20 lines of Python to your existing AI workflow and get:

• Immutable audit trails - Every step, artifact, and decision recorded with hash chains
• Complete provenance - Know exactly what produced each output, when, and by whom
• Lineage graphs - Visual DAG of Step → Artifact → Step relationships
• Snapshot replay - Reproduce past executions from stored artifacts
• Non-determinism transparency - Explicit marking of non-reproducible steps (LLM calls, etc.)
• Zero replacement - Keep your existing orchestration (LangChain, CrewAI, custom code)

---

Installation

pip install stardive

Requirements: Python 3.10+

Quick Start

5-Minute Example

Track your AI workflow with just a few decorators:

from stardive import StardiveContext

# Create audit context
ctx = StardiveContext()

# Decorate your functions
@ctx.step_meta(step_id="fetch", produces=["raw_data"])
def fetch_data():
    return {"data": [1, 2, 3]}

@ctx.step_meta(step_id="analyze", produces=["result"], depends_on=["raw_data"])
def analyze(raw_data):
    return {"sum": sum(raw_data["data"])}

# Execute with full audit trail
record = ctx.execute()

# Every step, artifact, and decision is now auditable
print(f"Run ID: {record.run_id}")
print(f"Complete audit trail stored with hash chain integrity")

That's it! You now have:

• Immutable execution records
• Artifact provenance
• Lineage graphs (API access)
• Replay capability

Alternative: Zero-Replacement Instrumentation

Already have working code? Add audit trails without refactoring:

from stardive.instrumentation import emit_run_start, emit_step_start, emit_step_end

# Wrap your existing workflow
run_id = emit_run_start(initiator={"user": "bob"})

emit_step_start(run_id, step_id="process", inputs={"data": [1, 2, 3]})
result = your_existing_function(data)  # Your code stays UNCHANGED
emit_step_end(run_id, step_id="process", outputs={"result": result})

# Full audit trail generated with zero business logic changes

Perfect for:

• LangChain/CrewAI workflows
• Jupyter notebooks
• Legacy batch jobs
• Gradual migration to full SDK

What Stardive Does NOT Do

Stardive is observation-only. We don't replace your existing tools:

• ❌ No workflow orchestration (use your existing orchestrator)
• ❌ No agent planning (we observe, not control)
• ❌ No dependency inference (you declare dependencies)
• ❌ No AI models or business logic (bring your own)
• ❌ No correctness checking (we capture truth, not judge it)

Use Cases

Stardive is designed for regulated environments where AI decisions must be defensible:

Industry Examples

Industry	Use Case	Why Stardive?
Financial Services	Credit scoring, fraud detection, algorithmic trading	Prove model decisions to regulators (FCRA, ECOA)
Healthcare	Clinical decision support, diagnosis assistance	Document AI's role in patient care (HIPAA, FDA)
Legal	Contract analysis, case research, e-discovery	Maintain chain of custody for AI evidence
Government	Benefits determination, policy analysis	Transparency & accountability (APA, FOIA)
Insurance	Claims processing, underwriting	Audit AI decisions for fairness & compliance

Key Requirements Stardive Solves

• Regulatory compliance: Full audit trail for GDPR, AI Act, FDA, FCRA, etc.
• Reproducibility: Prove AI decisions can be replayed from stored artifacts
• Accountability: Answer "How did the AI reach this conclusion?"
• Defensibility: Provide evidence in disputes, audits, or litigation
• Trust: Demonstrate responsible AI deployment to stakeholders

How Stardive Compares

Tool	Purpose	Relationship to Stardive
LangChain / CrewAI	Agent orchestration	Use together - Stardive observes their execution
MLflow / Weights & Biases	ML experiment tracking	Different focus - Stardive is for production audit trails
Apache Airflow	Workflow orchestration	Use together - Stardive captures provenance
OpenTelemetry	Observability/telemetry	Complementary - Stardive adds artifact provenance
DVC / Pachyderm	Data versioning	Different - Stardive tracks execution, not just data

Stardive's unique value: Immutable audit trails with artifact provenance and replay capability, specifically designed for regulated AI.

Explicit Boundaries

Stardive Will NEVER

• Infer dependencies (user must declare)
• Plan workflows (user provides plan)
• Optimize execution (no auto-optimization)
• Judge correctness (only capture truth)
• Replace orchestrators or agents (observation only)

Stardive ONLY Does

• Capture execution truth
• Store artifacts immutably
• Build lineage graphs
• Enable replay from snapshots
• Provide audit evidence
