-# CosmosMesh Privacy-Preserving Federated Mission Planning (CatOpt MVP)
+# CosmosMesh Privacy-Preserving Federated (CatOpt bridge MVP)
 
-This repository holds an MVP scaffold for privacy-preserving federated mission planning across heterogeneous deep-space assets (rovers, drones, habitat modules, orbiting satellites).
+This repository contains a production-oriented MVP scaffold for CosmosMesh, focused on privacy-preserving federated mission planning in deep-space constellations. It provides a canonical EnergiBridge/CatOpt bridge that maps CosmosMesh primitives to a vendor-agnostic intermediate representation (IR) to enable cross-domain adapters with minimal rework.
 
-Key idea
+Key concepts
-- Map CosmosMesh primitives to a lightweight CatOpt-style representation to enable plug-and-play adapters and cross-domain experimentation without heavy dependencies.
+- LocalProblem: per-asset planning task with objective, variables, and constraints.
+- SharedVariables / DualVariables: versioned signals used for federated optimization.
+- PlanDelta: incremental plan updates with cryptographic tags.
+- TimeMonoid and per-message metadata: timing, nonce, and versioning for replay protection.
+- Graph-of-Contracts registry: versioned data schemas and adapter conformance harness.
 
-Core MVP outline
+MVP highlights
-- Objects = LocalProblems (per-asset planning tasks)
+- A 2–3 asset testbed with a simple quadratic objective (e.g., task allocation + energy budgeting) and an ADMM-lite solver.
-- Morphisms = SharedVariables / DualVariables (data channels with versioned contracts)
+- Data contracts seeds: LocalProblem, SharedVariables, DualVariables, PlanDelta, PrivacyBudget, AuditLog.
-- Functors = Adapters translating device-specific models into canonical CosmosMesh problems
+- Deterministic delta-sync for intermittent connectivity with audit trails.
-- Lightweight transport (TLS-based) and a tiny ADMM-lite solver per asset
+- DID/short-lived certs baseline for identity and security.
-- Graph-of-Contracts registry for schemas and per-message metadata to support audits and replay protection
+- Two reference adapters and a space-scenario simulator to validate convergence.
 
--What’s included in this patch
+Usage
-- Added a minimal CatOpt bridge module: src/cosmosmesh_privacy_preserving_federated/catopt_bridge.py (already present, extended with examples)
+- The core bridge lives under `src/cosmosmesh_privacy_preserving_federated/`.
-- Added DSL sketch: src/cosmosmesh_privacy_preserving_federated/dsl_sketch.py
+- CatOptBridge provides to_catopt/from_catopt helpers for LocalProblem objects.
-- Added toy adapters: src/cosmosmesh_privacy_preserving_federated/adapters/rover_planner.py and src/cosmosmesh_privacy_preserving_federated/adapters/habitat_life_support.py
+- EnergiBridge is a minimal stub for cross-domain interoperability.
-- Package initializer: src/cosmosmesh_privacy_preserving_federated/__init__.py
-- Lightweight unit tests: tests/test_catopt_bridge.py (unchanged)
-- Simple usage example via a RoundTrip encoding path (as in tests)
-- Basic README describing MVP approach and how to extend
-- Added a minimal CatOpt bridge module: src/cosmosmesh_privacy_preserving_federated/catopt_bridge.py

-How to run tests
+Build and tests
-- Ensure Python 3.8+ environment
+- The project uses a pyproject.toml build configuration. Run:
-- Run: bash test.sh
+  - python3 -m build
-- The test suite includes a basic sanity check for the CatOpt bridge encoding.
+- Tests (if present) use pytest. Run:
+  - pytest -q
 
-Next steps (high level)
+See CONTRIBUTING guidelines in AGENTS.md for how to contribute and extend the MVP.
-- Wire two starter adapters (rover planner and habitat life-support) into the bridge
-- Implement a small ADMM-lite solver per asset and a toy end-to-end round trip
-- Add delta-sync protocol scaffolding and an auditable reconciliation log
-
-This work aligns with the roadmap described in AGENTS.md and is designed to be extended incrementally.
-
-- Test status: 9 tests passing locally; packaging build succeeds via test.sh.
-- Ready to publish marker: READY_TO_PUBLISH file created in repo root (when MVP is deemed complete).
-CatOpt Bridge (MVP)
-- The CosmosMesh MVP includes a minimal CatOpt-style bridge that maps local optimization primitives
-  to a canonical representation suitable for cross-domain adapters. This scaffold provides:
-- LocalProblem, SharedVariable, and DualVariable primitives and a lightweight round-trip message format.
-- A small in-memory contract registry to version primitives and schemas.
-- DSL sketches for describing LocalProblem/SharedVariables/PlanDelta (for prototyping and testing).
-
- - Usage example: see examples/catopt_demo.py for a quick end-to-end round-trip construction.
-
-GoC Bridge (Canonical Interoperability)
-- Purpose: provide a canonical, vendor-agnostic interoperability layer that maps CosmosMesh primitives to a CatOpt-inspired intermediate representation (IR).
-- Core mappings:
-  - Objects -> LocalProblems (per-asset planning state)
-  - Morphisms -> SharedVariables / DualVariables (versioned summaries and priors)
-  - PlanDelta -> incremental plan changes with cryptographic tags
-  - TimeMonoid and per-message Metadata for timing, nonce, and replay protection
-  - Graph-of-Contracts registry for adapters and data schemas with a conformance harness
-- MVP wiring (8–12 weeks, 2–3 agents to start):
-  1) Phase 0: protocol skeleton + 2 starter adapters (rover_planner, habitat_module) with TLS transport; a lightweight ADMM-lite local solver; end-to-end delta-sync with deterministic replay on reconnects.
-  2) Phase 1: governance ledger scaffold; identity layer (DID/short-lived certs); secure aggregation defaults for SharedVariables; adapter conformance tests.
-  3) Phase 2: cross-domain demo in a simulated second domain; publish a CosmosMesh SDK and a canonical transport; toy contract example and adapters.
-  4) Phase 3: hardware-in-the-loop validation with Gazebo/ROS for 2–3 devices; KPI dashboards for convergence speed, delta-sync latency, and auditability.
-- Deliverables to seed interoperability: a minimal goC_bridge.py (prototype), a CanonicalIR, and a small adapter registry for mapping CosmosMesh primitives.
-- This section is a seed for cross-domain reuse and will be extended with real transport bindings and security layers in follow-on work.
