FeedTrust MVP: Production-Grade Architecture

Overview
- FeedTrust is a modular, blockchain-backed access-control and provenance layer for cross-venue market data feeds. The MVP demonstrates policy-driven data access with verifiable provenance across two venues, via adapters and a simple aggregator.

Tech Stack (Python)
- Policy DSL: policy.py – a lightweight DSL-ish syntax and compiler for access rules.
- Provenance Ledger: ledger_merkle.py – Merkle-tree based proofs of data lineage.
- Adapters: adapters/fix.py, adapters/websocket.py – toy adapters bridging two feed types to a canonical signal format.
- Aggregation: aggregation.py – cross-venue data mixing with lightweight provenance tagging.
- Core: core.py – orchestrates policy checks, ledger interactions, and end-to-end flow.
- Tests: tests/ – unit and integration tests ensuring policy enforcement, ledger proofs, and end-to-end flow.
- Packaging: pyproject.toml – production-grade packaging metadata; README and READY_TO_PUBLISH as per spec.

How to Run (locally)
- Ensure Python 3.11+ is installed.
- Install test dependencies: pytest
- Run tests: ./test.sh
- Build package: python -m build
