CosmosMesh Privacy-Preserving Federated Mission Planning

Architecture overview
- Language: Python for MVP scaffolding (scaffold only)
- Core package: cosmosmesh_privacy_preserving_federated_
- Tests: pytest-driven in tests/ directory
- Build: Python packaging with pyproject.toml using setuptools

How to contribute
- Run tests with ./test.sh
- Package name and version are defined in pyproject.toml
- README describes how to extend the MVP and plug in adapters

Testing commands
- Build the project: python3 -m build
- Run tests: pytest -q
- Run the complete test script: bash test.sh

Rules
- Do not modify public API semantics for MVP scaffolding unless asked
- Focus on small, correct changes and clear documentation

CosmosMesh CatOpt bridge (MVP)
- We are prototyping a lightweight interoperability bridge that maps CosmosMesh MVP primitives to a CatOpt-style representation (Objects/ Morphisms/ Functors) to enable cross-domain experimentation without heavy dependencies.
- Starter adapters: rover and habitat module adapters exposing simple interfaces for readState, exposeLocalProblemData, and applyCommand.
- Transport: TLS-based, e.g., MQTT/REST for prototyping.
- Deliverables: a minimal CatOpt bridge module (src/cosmosmesh_privacy_preserving_federated/catopt_bridge.py), a small registry graph for contracts, and a DSL sketch to describe LocalProblem/SharedVariables/DualVariables/PlanDelta.
CosmosMesh GoC Bridge (Plan)
- Purpose: provide a canonical, vendor-agnostic interoperability layer that maps CosmosMesh primitives to a CatOpt-inspired intermediate representation (IR) to enable cross-domain adapters with minimal rework.
- Core concepts:
  - Objects -> LocalProblems (per-asset planning state)
  - Morphisms -> SharedVariables / DualVariables (versioned summaries, priors)
  - PlanDelta -> incremental plan changes with cryptographic tags
  - TimeMonoid / Metadata -> per-message timing, nonce, signatures for replay protection
  - Graph-of-Contracts registry -> versioned data schemas and adapter 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; lightweight ADMM-lite local solver; delta-sync with deterministic replay on reconnects;
  2) Phase 1: governance ledger scaffold; identity layer (DID/short-lived certs); secure aggregation 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 examples 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, auditability.
- Deliverables to align with repo: add a minimal goC_bridge.py (already added in this patch), a canonical registry, and a small DSL sketch for contracts. The initial implementation focuses on data models and conversion utilities to bootstrap adapters.
- Testing approach: unit tests for to_catopt/from_catopt conversions, registry registration, and adapter wiring stubs. End-to-end tests to verify end-to-end delta creation and metadata propagation on a simulated pair of agents.
- Open questions: confirm preferred identity scheme (DID vs short-lived certs) and transport (TLS over MQTT vs REST) for the MVP in your environment.
