+# GreeksHub: Federated Cross-Venue Greeks MVP
+
+Architecture overview
+- Local primitives: LocalHedgeProblem, SharedGreeks, DualVariables, PlanDelta, AuditLog, PrivacyBudget.
+- Graph-of-Contracts (GoC): lightweight in-process registry to version adapters and data contracts.
+- Adapters: two starter adapters (price/vol feed, broker/execution) with TLS transport concept.
+- ADMM-lite coordinator: edge-friendly coordinator that aggregates locally computed signals with secure summaries.
+- Deterministic replay: plan deltas and signals are replayable for backtests and audits.
+- Governance ledger: signed events, lightweight DID-based identity, policy checks.
+
+Scope and testing
+- Language: Python (production-ready, strong typing, tests).
+- Testing: pytest with a small test suite; test.sh orchestrates tests and packaging sanity checks.
+
+Development workflow
+- Add small, composable components first; extend registry and adapters later.
+- Run tests locally; ensure packaging metadata compiles (python build) as part of test.sh.
+
+Contribution rules
+- Follow minimal, well-documented changes; preserve existing contracts.
+- Write tests for any new public API surface.
+
+Checklist for publishing (to be checked by the final phase):
+- README.md with marketing and usage detail.
+- AGENTS.md present.
+- test.sh runs pytest and python -m build for packaging sanity.
+- READY_TO_PUBLISH present (empty file to signal completion).

-# idea147-greekshub-federated-cross
+GreeksHub: Federated Cross-Venue Options Greeks Aggregation for Hedge Optimization
 
-Source logic for Idea #147
\ No newline at end of file
+Overview
+- A production-ready, Python-based MVP that demonstrates canonical primitives for local hedge problems, aggregated signals, and incremental hedge actions across multiple venues.
+- Core primitives mirror CatOpt-like representations: LocalHedge, SharedGreeks, PlanDelta, with Governance via AuditLog and PrivacyBudget.
+- A Graph-of-Contracts (GoC) skeleton registry to version adapters and data contracts; two toy adapters to bootstrap interoperability.
+- An ADMM-lite coordinator enabling edge/cloud cross-venue aggregation with deterministic replay semantics.
+
+What's included
+- Core primitives (src/idea147_greekshub_federated_cross/core.py)
+- GoC registry skeleton (src/idea147_greekshub_federated_cross/registry.py)
+- Adapters (price/vol feed, broker) under src/idea147_greekshub_federated_cross/adapters/
+- Lightweight coordinator (src/idea147_greekshub_federated_cross/coordinator.py)
+- Minimal tests (tests/test_greeks_hub.py)
+- Packaging metadata (pyproject.toml) and test script (test.sh)
+
+Usage
+- Run tests: ./test.sh
+- For local experimentation, import modules from idea147_greekshub_federated_cross.*
+
+Note
+- This is an MVP scaffold intended to evolve into a production-ready architecture as per the project spec.
