HopeMesh 2.0

HopeMesh 2.0 is a Python package for federated humanitarian allocation workflows in disrupted networks.

It provides:

• Canonical primitives for LocalProblem, SharedVariables, PlanDelta, Policy, AttestationHint, AuditLog, and PrivacyBudget.
• A Graph-of-Contracts registry for versioned schemas and adapters.
• A tamper-evident governance ledger.
• Small SDK helpers for deterministic construction and delta merging.
• A CLI for local registry and ledger snapshots.

Layout

• hopemesh/core.py: primitive dataclasses and fingerprinting helpers.
• hopemesh/contracts.py: Graph-of-Contracts and governance ledger.
• hopemesh/sdk.py: DSL-style constructors and merge helpers.
• hopemesh/cli.py: local CLI for registry and ledger operations.
• tests/: unit tests for primitives, registry, ledger, and helpers.

Quick Start

python3 -m pip install --upgrade build
python3 -m build
./test.sh

CLI

python -m hopemesh.cli --version
python -m hopemesh.cli registry init --store .hopemesh/state.json
python -m hopemesh.cli registry add-schema --name allocation --schema-version 1.0 --definition-json '{"fields":["region","qty"]}'
python -m hopemesh.cli ledger verify

Notes

• The project is intentionally dependency-light and uses the Python standard library for validation, hashing, and snapshotting.
• test.sh runs python3 -m build, a smoke import/instantiate check, and the unit test suite.
