+# FLASHPLAN AGENTS
+
+Overview
+- FlashPlan is a federated edge planner for cross-venue execution. This repository provides a minimal MVP core to bootstrap development and testing.
+
+Architecture
+- Core primitives: LocalProblem, SharedVariables, PlanDelta
+- Edge planner: lightweight optimization with a simple ADMM-lite coordinator
+- Adapters: venue A, venue B; mock risk center
+- Transport: TLS-stub boundary to illustrate secure channels (no real network in MVP)
+- Delta-sync: deterministic reconciliation on reconnects
+
+Tech Stack
+- Python 3.11+ (typing, dataclasses, small in-process simulations)
+- Tests with pytest
+- Packaging via setuptools (pyproject.toml)
+
+How to run tests
+- ./test.sh
+- The script runs pytest and python -m build to verify packaging.
+
+Development Rules
+- Implement smallest correct change first; small, well-scoped PRs preferred.
+- Favor plain Python modules with clear interfaces; add tests for new behavior.
+- Do not publish or push to remote without explicit user instruction.
