Renamed the Python package from autopr to codeflow_engine throughout the codebase to align with the project's naming conventions, and added comprehensive Architecture Decision Records (ADRs) to document key technology choices.

Changes

Package Structure

  • Renamed autopr/ directory to codeflow_engine/
  • Updated pyproject.toml: package declaration, entry points, plugins, coverage paths, isort config
  • Updated setup.py: entry points and package data

Import Refactoring

  • Replaced 697+ import statements: from autopr.*from codeflow_engine.*
  • Updated dynamic imports in string literals (module paths, logger names)
  • Fixed test mocking/patching references
  • Updated Alembic migration imports

Code Example

# Before
from autopr.engine import AutoPREngine
from autopr.config import AutoPRConfig

# After
from codeflow_engine.engine import AutoPREngine
from codeflow_engine.config import AutoPRConfig

Architecture Decision Records Added

Created comprehensive ADRs to document architecture decisions that were never formally recorded:

  • ADR-0019: Python-Only Architecture - Documents the actual Python-only implementation with comprehensive evaluation of alternatives including Rust (via PyO3/maturin for performance-critical components), C# (.NET 8+ hybrid architecture), Go (for microservices), and polyglot approaches. Includes detailed separation of concerns strategies, migration paths with decision tree, and concrete code examples. Explains why Python-only was chosen and how to migrate to Rust when performance optimization is needed.

  • ADR-0020: Package Naming Convention - Documents the autoprcodeflow_engine rename with complete migration guide, backward compatibility strategy, and rationale for the dual naming approach (CLI vs package).

  • ADR-0021: Repository Structure - Full evaluation of monorepo vs multi-repo strategy with recommendation to split into 3-4 focused repositories (core engine, UI, infrastructure, templates). Includes detailed 12-week implementation plan, coordination strategy, and success metrics.

  • ADR Index - Created comprehensive navigation guide (docs/adr/README.md) for all 21 architecture decisions with status tracking and quick reference.

  • Updated Status - Marked ADR-0001 (Hybrid C#/Python Architecture) as superseded and ADR-0002 (gRPC Communication) as deprecated to reflect actual implementation.

Separation of Concerns

ADR-0019 demonstrates how separation of concerns is achieved in the Python-only architecture through:

  • Layered Architecture: Clear domain, application, infrastructure, and presentation layers
  • Domain-Driven Design: Bounded contexts, dependency inversion, repository pattern
  • Plugin System: Extensibility via autopr.* plugin namespaces
  • Type Safety: Pydantic v2 models enforce contracts at module boundaries
  • Microservices-Ready: Each bounded context can be extracted as independent service

Backward Compatibility

  • Configuration files remain autopr.yaml / autopr.yml
  • Plugin namespaces unchanged (autopr.actions, autopr.integrations, etc.)

Added comprehensive ADRs in commit 38829af:

ADR-0019: Python-Only Architecture - Documents the actual Python-only implementation and explains why the originally proposed hybrid C#/Python architecture (ADR-0001) was not pursued. Includes detailed tech stack (Python 3.12+, FastAPI, PostgreSQL, Redis) and migration summary.

ADR-0020: Package Naming Convention - Documents the autoprcodeflow_engine rename with a complete migration guide, backward compatibility strategy, and rationale for the dual naming approach (CLI vs package).

ADR-0021: Repository Structure - Full evaluation of monorepo vs multi-repo strategy with recommendation to split into 3-4 focused repositories (core engine, UI, infrastructure, templates). Includes detailed implementation plan with 12-week timeline, coordination strategy, and success metrics.

Also updated ADR-0001 and ADR-0002 to mark them as superseded/deprecated, and created a comprehensive ADR index (docs/adr/README.md) for easy navigation of all 21 architecture decisions.

@copilot you didnt even consider rust. sure python only is the best option. consider separat. and no c#? consider separation of concens etc

… of concerns

- Added comprehensive alternatives evaluation section comparing:
  * Python-only (chosen)
  * Rust for performance-critical components (PyO3/maturin)
  * C# (.NET 8+) hybrid architecture
  * Go for microservices
  * Polyglot microservices approach

- Each option includes:
  * Technology stack details
  * Pros and cons analysis
  * Separation of concerns strategy
  * Decision rationale

- Added detailed "Separation of Concerns in Python" section showing:
  * Layered architecture (domain, application, infrastructure layers)
  * Domain-Driven Design principles (bounded contexts, dependency inversion)
  * Plugin architecture for extensibility
  * Repository and service patterns
  * Module independence and microservices-ready design

- Expanded migration path with 4 detailed options:
  * Option A: Gradual Python optimization (Cython, PyPy)
  * Option B: Rust extensions via PyO3 (recommended for CPU-bound work)
  * Option C: C# microservices (for complex business logic)
  * Option D: Full polyglot microservices

- Added decision tree for migration path selection
- Included concrete Rust integration example with code samples
- Explained why Rust is preferred over C#/Go for performance extensions
- Added references for Rust, C#, Go, and architecture patterns
- Demonstrated that separation of concerns is achieved through design patterns, not just language choice

Expanded ADR-0019 in commit 1b28109 to include comprehensive evaluation of alternatives:

Rust (Option 2): Full evaluation of Rust + Python hybrid via PyO3/maturin, including performance benefits, memory safety, and concrete migration path with code examples. Identified as the recommended path for CPU-bound optimization.

C# (Option 3): Complete assessment of C# (.NET 8+) hybrid architecture, including pros/cons and why it wasn't chosen despite being proposed in ADR-0001.

Go (Option 4): Evaluated Go for microservices approach.

Separation of Concerns: Added detailed section demonstrating how Python-only achieves this through:

  • Layered architecture (domain/application/infrastructure layers)
  • Domain-Driven Design (bounded contexts, dependency inversion, repository pattern)
  • Plugin system and clear module boundaries
  • Type safety via Pydantic v2

The ADR now includes a decision tree for choosing migration paths and explains that separation of concerns is achieved through software design patterns, not language choice. Rust is positioned as the preferred option for performance-critical extensions when needed.

Proposed
**Deprecated** (Related to ADR-0001 which was superseded)

This ADR was proposed for cross-language communication in a hybrid C#/Python architecture, but was never implemented. The project uses Python-only architecture (see [ADR-0019](0019-python-only-architecture.md)), eliminating the need for cross-language communication.
