# CosmosMesh Privacy-Preserving Federated Mission Planning (MVP)

CosmosMesh is a privacy-preserving, offline-first federation platform designed for distributed planning across heterogeneous space assets (rovers, drones, habitat modules, satellites). This MVP implements a canonical bridge (EnergiBridge / CatOpt-Bridge style) and an initial DSL to bootstrap interoperability, adapters, and end-to-end testing.

Key goals of the MVP
- Map CosmosMesh primitives to a vendor-agnostic intermediate representation (IR): Objects = LocalProblems, Morphisms = SharedVariables/DualVariables, PlanDelta, PrivacyBudget, AuditLog, etc.
- Provide a simple DSL scaffold for LocalProblem, SharedVariables, PlanDelta, DualVariables, PrivacyBudget, AuditLog, and a PolicyBlock for safety/exposure rules.
- Supply tiny adapters and a conformance harness to kickstart multi-domain interoperability.
- Include a lightweight ADMM-like local solver for federated optimization and a delta-sync workflow for islanding scenarios.

What you get in this MVP
- A canonical bridge module that maps CosmosMesh primitives to a vendor-agnostic intermediate representation (IR).
- A minimal DSL sketch for core primitives and signals.
- Core data models and a conformance scaffold to bootstrap adapters and a small contract registry.
- Tests that exercise a roundtrip between the IR and local representations.

How to use this repo
- Install and run tests: see test.sh for a complete verification workflow.
- Run tests: bash test.sh
- See tests/test_catopt_bridge.py for a representative usage of the CatOpt-Bridge and the roundtrip semantics.

Project structure
- src/cosmosmesh_privacy_preserving_federated: core models and logic (LocalProblem, SharedVariables, PlanDelta, etc.)
- src/cosmosmesh_privacy_preserving_federated/adapters: starter adapters (rover_planner, habitat_module, etc.)
- tests: unit tests for the bridge, contracts, and basic flow
- README.md: this documentation

Development and contribution
- This MVP is designed to be extended in small, well-scoped steps. See AGENTS.md for repository-wide conventions and testing commands.
- To extend interoperability, add adapters implementing the canonical IR and use the conformance harness to validate compatibility before onboarding.

Roadmap (high level)
- Phase 0: protocol skeleton and 2 starter adapters with TLS transport; a lightweight ADMM-lite local solver; end-to-end delta-sync with islanding.
- Phase 1: governance ledger scaffolding; identity layer; secure aggregation defaults.
- Phase 2: cross-domain demo with a toy contract example and NovaPlan SDK bindings.
- Phase 3: hardware-in-the-loop validation and KPI dashboards.

This repository aims to be a practical foundation for cross-domain interoperability in privacy-preserving federated planning, with a clear path toward broader ecosystem reuse.
