SoundGraph Studio — Phase0 primitives

This repository contains Phase0 primitives for SoundGraph Studio: a content-addressed representation of AudioModule objects, an AudioPatch structure with a Merkle-based root for provable inclusion, and simple provenance events with cryptographic signatures.

What is included

• A small Python package idea44_soundgraph_studio_verifiable implementing:
  • AudioModule: content-addressed modules (SHA-256 over canonical JSON)
  • AudioPatch: nodes referencing module CIDs and edges; Merkle root over nodes+edges
  • ProvenanceEvent: lightweight signed events (ed25519) for tamper-evident audit trails
• Tests (pytest) that validate CID reproducibility, Merkle inclusion proofs, and signature verification
• Packaging (pyproject.toml + setup.cfg) and a test.sh that runs the test suite and verifies build

How to run tests

1. Make sure you have Python 3.8+ and python3 -m pip available.
2. Run:

./test.sh

This will install the package in editable mode, run pytest, and run python3 -m build to verify packaging.

Notes

• This is intentionally focused on Phase0 local graph primitives — a solid foundation for future delta-sync, adapters, and governance ledger work.
