+- Follow the style used in the repo (ASCII, concise code, docstrings where helpful)
 
-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.
+How to extend (high level)
+- Add more adapters (e.g., rover_planner, habitat_module) under a dedicated adapters module
+- Expand the DSL sketch to cover more primitives (DualVariables, PrivacyBudget, AuditLog, PolicyBlock)
+- Implement a small simulator to exercise delta-sync and islanding scenarios

-CosmosMesh Privacy-Preserving Federated Mission Planning (CatOpt bridge MVP)
+# CosmosMesh Privacy-Preserving Federated Mission Planning (MVP)
 
-This repository provides a production-oriented MVP scaffold for privacy-preserving, federated planning across heterogeneous deep-space assets. The CatOpt bridge maps CosmosMesh primitives into a vendor-agnostic intermediate representation to enable cross-domain adapters with minimal rework.
+This repository contains a minimal MVP oriented toward a CatOpt-inspired interoperability bridge for CosmosMesh primitives. It is intended to bootstrap inter-domain adapters and testing of a privacy-preserving federated planning workflow.
 
-- Core concepts
-- CatOpt bridge primitives and a minimal Graph-of-Contracts (GoC) registry
-- Lightweight adapters (rover_planner, habitat_module) over TLS
-- Minimal data contracts: LocalProblem, SharedVariables, DualVariables, PlanDelta, PrivacyBudget, AuditLog
-- End-to-end delta-sync sketch with deterministic offline replay
-- Basic security primitives (signatures, per-message metadata) suitable for MVP
+What you get in this MVP:
+- A canonical bridge module that maps CosmosMesh primitives to a vendor-agnostic intermediate representation (Objects, Morphisms, PlanDelta, etc.).
+- A tiny DSL sketch outlining LocalProblem, SharedVariables, PlanDelta, DualVariables, PrivacyBudget, and AuditLog.
+- Basic data-models and a conformance scaffold to help bootstrap adapters and a small registry for contracts.
+- Tests that exercise a roundtrip between the IR and local structures.
 
-Usage
-- Import modules under src/cosmosmesh_privacy_preserving_federated/
-- Run tests via ./test.sh (pytest-based tests included)
+Usage hints:
+- See tests/test_catopt_bridge.py for a usage example and expected round-trip behavior.
+- Extend the DSL sketch and bridge as you add more primitives and adapter specifics.
 
-This README intentionally keeps surface area small while documenting how to extend for a production-grade setup.
+Note: This is intentionally minimal to keep the MVP small and reliable; it will be extended in future iterations to cover full security, consent, and governance concerns.
 
--## Publishing Readiness
-
-- All tests pass (pytest) and packaging checks succeed via test.sh, which also validates Python packaging metadata.
-- This MVP includes core components: CatOpt bridge, Energi bridge, GoC bridge, a minimal DSL sketch, contract registry, and reference adapters.
-- To publish a production-ready artifact, the repository should expose a stable package (name: cosmosmesh-privacy-preserving-federated, version in pyproject.toml) and a comprehensive README describing public APIs, usage, and integration steps.
-- Next step for publishing: ensure the release is green (tests pass, build succeeds) and place an empty READY_TO_PUBLISH flag at the repo root to signal readiness. The publishing pipeline will detect this file as a go/no-go signal.
-
-## EnergiBridge & CatOpt Interop (Extra MVP guidance)
-
-- This repository already includes an EnergiBridge module and a CatOpt-inspired bridge to bootstrap cross-domain interoperability. The goal is to map CosmosMesh primitives into a canonical CatOpt-like intermediate representation (IR) so adapters can be dropped into other domains with minimal changes.
-- Core primitives (as seeds):
-  - Objects = LocalProblems (per-asset planning tasks)
-  - Morphisms = SharedVariables / DualVariables (versioned signals and priors)
-  - PlanDelta = incremental plan changes with cryptographic tags
-  - PrivacyBudget / AuditLog blocks for governance and provenance
-  - TimeMonoid for rounds; per-message metadata for replay protection
-  - Graph-of-Contracts registry for adapter schemas and conformance
-- MVP extension plan (high level):
-  - Phase 0: protocol skeleton + 2 starter adapters (rover_planner, habitat_module) with TLS transport; ADMM-lite local solver; deterministic delta-sync.
-  - Phase 1: governance ledger scaffolding; identity layer; secure aggregation defaults for SharedVariables.
-  - Phase 2: cross-domain demo (space-domain + ground-domain) and EnergiBridge SDK bindings; toy contract example.
-  - Phase 3: hardware-in-the-loop validation with KPI dashboards (convergence speed, delta-sync latency, auditability).
-- Minimal DSL sketch and toy adapters can be drafted to bootstrap interoperability with EnergiBridge. See examples/contract_sketch.md for a starter description.
-
-## MVP Extension Notes
-
-- EnergiBridge canonical bridge mappings exist and align with the EnergiBridge/CatOpt integration plan.
-- The GoC registry and DSL seeds are in place to support contract versioning and adapter conformance.
-- Reference adapters (rover_planner, habitat_module) demonstrate end-to-end interoperability over TLS.
-- If you want, I can draft a toy contract sketch and outline two adapters to bootstrap CosmosMesh interoperability with EnergiBridge, plus a 2-venue MVP calendar with concrete milestones.
