+# CrisisGuard - Agents & Architecture
+
+- Architecture: modular Python package under crisisguard/ with a minimal Graph-of-Contracts, LocalPlan/SharedSignals/PlanDelta models, and two starter adapters. A governance log anchors actions via cryptographic hashes.
+- Tech stack: Python 3.8+, dataclasses, JSON, hashing, and a tiny in-memory registry. Adapters are plain Python modules intended to be swapped with real implementations.
+- Testing: pytest-based tests validating contract registry and delta application. test.sh runs pytest after optional build to verify packaging works.
+- Commands you should know:
+- Build: python -m build
+- Test: bash test.sh
+- Run quick checks: rg 'LocalPlan|PlanDelta' -n crisisguard -S
+- Run adapters locally: python -m crisisguard.toy_scenario.disaster_scenario
+
+- Rules:
+- Do not rely on network services for the core tests. The toy scenario runs in-memory.
+- Keep changes minimal and well-documented. Follow the small-change principle.
+- If you introduce new components, add tests and update AGENTS.md accordingly.

+# CrisisGuard: Federated Privacy-Preserving Crisis Response Sandbox
 
-Source logic for Idea #143
+CrisisGuard is a federation-oriented platform for humanitarian crisis response. It defines canonical representations for plans, signals, and deltas, enables offline-first delta-sync, secure aggregation, and tamper-evident governance logs anchored by hashes. It includes a Graph-of-Contracts registry and adapters marketplace skeleton, a toy disaster scenario, and an SDK-friendly Python package structure for rapid prototyping and testing.
+
+What you get in this repository
+- Core data models: LocalPlan, SharedSignals, PlanDelta
+- Tamper-evident governance log with hash chaining
+- Lightweight Graph-of-Contracts registry for adapters
+- Two starter adapters: NeedsCollector and ResourcePlanner
+- Toy disaster scenario harness demonstrating offline delta-sync
+- Basic tests validating contracts and delta application
+- Packaging scaffold (pyproject.toml) and test runner (test.sh)
+- Developer guide (AGENTS.md) describing architecture and testing commands
+
+Notes on scope
+- This is a production-minded scaffold (not a full MVP). It focuses on solid architecture, tests, and a clear path for plugging in adapters and governance components.
+- All code is designed to be extended into a larger distributed system with TLS transport, DID-based identities, and crypto-enabled privacy primitives.
+
+How to run locally (summary)
+- Install dependencies for tests: see test.sh and requirements (pytest is used).
+- Run tests: bash test.sh
+- Build package: python3 -m build
+
+This repository is meant to be extended by subsequent sprint agents in the SWARM workflow.
