+Repository: idea139-opendeployment-quilt-federated
+
+Purpose
+This repo contains a reference Python implementation of the OpenDeployment Quilt primitives and a minimal runtime surface for adapters and coordination logic. It is intentionally small and designed for extension by automated agents and human contributors.
+
+Architecture
+- src/idea139_opendeployment_quilt_federated/models.py: canonical pydantic models (LocalPlan, SharedSignals, PlanDelta, AuditLog)
+- src/idea139_opendeployment_quilt_federated/registry.py: adapter registry and conformance checks
+- src/idea139_opendeployment_quilt_federated/adapters/: adapter skeletons for GitHub Actions and Jenkins
+- src/idea139_opendeployment_quilt_federated/coordinator.py: simple async aggregator demonstrating signal aggregation and PlanDelta generation
+
+Tech stack
+- Python 3.8+
+- pydantic for schema models
+- pytest for tests
+- setuptools for packaging (pyproject.toml present)
+
+Testing and CI rules
+- Run `bash test.sh` in repository root. It runs `pytest` and `python3 -m build` to validate packaging metadata.
+- Tests must be green before publishing.
+
+Development rules for agents
+- Always use apply_patch for file edits.
+- Respect the existing models and API; make the smallest change needed for a feature or bug fix.
+- Do not commit or modify external secrets or credentials.
+- If adding dependencies, update pyproject.toml and ensure `python3 -m build` still succeeds.
+
+How to extend
+- Add new adapters under adapters/ and register them via registry.register_adapter
+- Add conformance tests under tests/ for new adapters
+- When adding public API, include type-hinted functions and pydantic models for validation

+# OpenDeployment Quilt — Reference Python Implementation
 
-Source logic for Idea #139
+This repository contains a focused reference implementation for the OpenDeployment Quilt idea: a federated, consent-based observability fabric for CI/CD across organizations and clouds.
+
+Goals in this repo
+- Provide canonical data primitives (LocalPlan, SharedSignals, PlanDelta, AuditLog) as pydantic models
+- Provide a small registry and conformance checks for adapters
+- Ship two adapter skeletons (GitHub Actions and Jenkins) to demonstrate the adapter contract
+- Provide a lightweight async coordinator that shows how aggregated signals can be reduced into PlanDelta suggestions
+- Tests, packaging metadata, and developer docs so agents and humans can extend the project
+
+Quickstart
+1. Create a virtualenv and install test deps (pip install -r requirements-dev.txt) or simply run tests with any pytest-enabled environment.
+2. Run tests: `bash test.sh`
+
+Project layout
+- src/idea139_opendeployment_quilt_federated: package source
+- tests: pytest tests
+
+Important files
+- `pyproject.toml` - packaging metadata (name = idea139-opendeployment-quilt-federated)
+- `AGENTS.md` - developer rules and architecture notes
+- `test.sh` - runs pytest and `python3 -m build`
