+Overview
+- CityPulse is a cross-domain urban resource optimization platform emphasizing privacy-preserving federated coordination with an offline-first delta-sync protocol.
+- This repository contains a production-oriented MVP scaffold in Python that demonstrates core concepts: LocalProblems, SharedSignals, PlanDelta, DualVariables, and an auditable governance trail via AuditLog.
+
+Architecture (high level)
+- Core models (src/idea171_citypulse_participatory_digital/core.py): LocalProblem, SharedSignals, PlanDelta, DualVariables, and AuditLog.
+- Delta store and replay (src/idea171_citypulse_participatory_digital/delta.py): deterministic delta history and replay capability.
+- Solver (src/idea171_citypulse_participatory_digital/solver.py): a minimal ADMM-lite aggregator over dual variables.
+- Adapters (src/idea171_citypulse_participatory_digital/adapters): starter bindings for DER and Water Pump controllers.
+- Public APIs are intentionally lightweight for MVP; this repo provides a stable foundation for rapid pilots and extension via adapters and governance.
+
+Tech Stack
+- Language: Python 3.9+ (typing, dataclasses, lightweight architecture)
+- Key concepts: LocalProblems (domain tasks), SharedSignals (privacy-preserving signals), PlanDelta (contractual delta actions), DualVariables (shadow prices), AuditLog (tamper-evident-like logging proxy).
+- No external services required for MVP; simple in-process delta store and a toy ADMM-like solver to illustrate coordination.
+
+Development and Testing
+- Tests: pytest tests/test_core.py
+- Test script: test.sh (runs pytest, then builds the package via python3 -m build)
+- Packaging: pyproject.toml with a production-ready package name idea171-citypulse-participatory-digital
+
+Running locally
+- Install dependencies (none beyond stdlib for MVP)
+- Run tests: ./test.sh
+- Build package: python3 -m build
+
+Contributing rules
+- One change at a time, with tests updated accordingly.
+- Ensure tests pass before publishing readiness.

-# idea171-citypulse-participatory-digital
+# CityPulse: Participatory Digital Twin (Open-Source MVP)
 
-Source logic for Idea #171
\ No newline at end of file
+CityPulse aims to be a modular, open-source platform for cross-domain urban resource optimization with privacy-preserving, offline-first federated coordination. This MVP scaffold demonstrates core concepts and provides a path toward production-grade integration with adapters, governance, and a lightweight simulator.
+
+What’s included
+- Core domain models: LocalProblem, SharedSignals, PlanDelta, DualVariables, AuditLog.
+- Delta store with deterministic replay for auditable governance trails.
+- Minimal ADMM-lite solver to illustrate federated coordination semantics.
+- Starter adapters: DERControllerAdapter and WaterPumpControllerAdapter.
+- Lightweight packaging setup (pyproject.toml) and test harness.
+
+How to run
+- Run tests and build package: ./test.sh
+- The test suite exercises core data structures and adapter bindings.
+
+Packaging and publishing
+- The package is named idea171-citypulse-participatory-digital and is provisioned for publishing to PyPI or a private registry.
+- A READY_TO_PUBLISH file will be created when the repository state fully matches publishing requirements.
+
+Roadmap (high level)
+- Phase 0: Skeleton protocol core + adapters over TLS; end-to-end delta-sync.
+- Phase 1: Governance ledger scaffolding and identity layer.
+- Phase 2: Cross-domain demo in a simulated district.
+- Phase 3: Hardware-in-the-loop validation.
+
+Enjoy contributing and shaping the CityPulse ecosystem.
