Phase Atlas SDK

The PTEM SDK is a read-only, manifest-first interface for frozen Phase Atlas artifacts. It is designed for deterministic ingestion, provenance checks, and governance-safe replay across evaluation and institutional workflows.

Key capabilities

• Manifest-backed loading of frozen Phase Atlas measurement artifacts
• Version-tagged retrieval with freeze metadata and schema identifiers
• Pre-ingest artifact integrity checks through SHA256 hash verification
• Deterministic replay support for validation and governance review

Safe-by-design

• Phase Atlas remains the measurement surface; PAC remains the downstream conditioning layer
• Non-forecasting outputs only
• No track modification or event generation functionality is exposed
• No proprietary internal operator logic or derivation internals are disclosed

What’s included

• Reference schemas and typed payload definitions
• Manifest and receipt field expectations for governed ingestion
• Version discipline for published schema increments
• Deterministic payload examples for integration testing
