OpenGrowth Privacy-Preserving Federated Growth (MVP)

Overview
- A privacy-preserving federated platform enabling startups to run, share, and benchmark growth experiments
  (pricing, onboarding, activation, funnel optimization) without exposing raw user data.
- Local metrics are retained by each startup; secure aggregation yields aggregated results with confidence intervals.
- Data contracts, a schema registry, and a lightweight Graph-of-Contracts enable governance and cross-startup benchmarking.

Core MVP Components (visible in this repo)
- opengrowth_privacy_preserving_federated_
  - SchemaRegistry / ExperimentTemplate (minimal MVP) with tests validating basic behavior.
- opengrowth_privacy_preserving_federated_/contracts.py
  - LocalExperiment, SharedSignals, PlanDelta: lightweight DSL primitives for local experiments and cross-start signals.
  - GraphOfContracts: tiny in-process registry for versioned contracts.
- opengrowth_privacy_preserving_federated_/__init__.py
  - Exposes core MVP primitives and the new contract primitives for iterative federation development.

How to run tests and build locally
- Install in editable mode and run tests:
  - bash test.sh
- This ensures packaging works and the pytest suite passes.

Extending OpenGrowth (Recommended next steps)
- Implement a REST/MQTT adapter layer to connect to common analytics stacks (GA4, Segment, Amplitude) and CRM pipelines.
- Expand the governance layer with versioned templates, access controls, and audit logs.
- Implement a real secure aggregation backend (e.g., ADMM, DP knobs) and a cloud-anchored ledger for reproducibility.
- Build a small developer-focused DSL sketch and toy adapters to bootstrap cross-startup federation (CatOpt-like bridge).

Notes
- This repository is designed as a stepping-stone toward a production-grade platform. The MVP is intentionally small but designed for extension with minimal surface area impact.
- The test suite validates the core MVP contracts and aggregation primitives; ongoing work should extend tests for new features.

For contributors
- Keep changes small and well-scoped; add tests for any public API you introduce.
- Update AGENTS.md if architecture or contribution rules evolve.
