Summary

This PR refactors the service dependency injection pattern across the codebase, with a primary focus on the PlanService and related services. The refactoring moves from a mixed initialization pattern (combining constructor injection with lazy initialization) to explicit, constructor-based dependency injection, ensuring the DI container has full responsibility for wiring all dependencies at instantiation time.

Changes

PlanService DI Pattern Refactoring

  • Explicit Constructor Injection: All service dependencies are now declared as constructor parameters with proper type hints
  • Eliminated Lazy Initialization: Removed property-based lazy initialization patterns that deferred dependency resolution
  • Container-Driven Wiring: DI container now handles all dependency resolution and injection at service instantiation
  • Dependency Clarity: Constructor signatures now explicitly declare all required dependencies, improving code readability and IDE support

Related Service Updates

  • Updated dependent services to align with the new DI pattern
  • Ensured backward compatibility where applicable
  • Refactored service factory methods to work with the new injection model

Configuration & Setup

  • Updated DI container configuration to properly wire all service dependencies
  • Added explicit bindings for all service dependencies in the container setup
  • Verified all service instantiation paths use the DI container

Testing

BDD Test Coverage

  • Added comprehensive BDD tests (features/services/dependency_injection.feature) to validate DI wiring patterns
  • Tests verify that all service dependencies are correctly injected at instantiation time
  • Scenarios cover:
    • Service instantiation with all required dependencies
    • Dependency resolution through the DI container
    • Proper initialization order and dependency graph validation
    • Error handling for missing or misconfigured dependencies

Existing Test Suite

  • All existing unit tests updated to work with the new DI pattern
  • Integration tests verified to ensure services function correctly with injected dependencies
  • No regression in test coverage

Quality Gates Status

✅ Code Coverage: Maintained at ≥97% (coverage report included)
✅ Nox Test Suite: All checks passing
✅ Type Hints: Full type annotation coverage for all constructor parameters
✅ Linting: All style and quality checks passing

Related Documentation

This refactoring implements the patterns and principles defined in ADR-003 (docs/adr/dependency-injection.md), which establishes the standard for dependency injection across the codebase.

Implementation Attempt — Tier 1: haiku — Success

Fixed two CI failures (lint and typecheck) in the refactor/v360/unify-service-initialization branch:

  1. Lint (RUF022) — Sorted __all__ in src/cleveragents/domain/contexts/__init__.py to alphabetical order: ScopeChainResolver, ScopeResolutionContext, ScopeResolverRegistry, ScoredFragment.

  2. Lint (F401) — Removed unused ScopeChainResolver import from examples/scope_resolvers/git_issue_resolver.py (it was only used as a type annotation but was not referenced in the file).

  3. Typecheck (reportAttributeAccessIssue) — Fixed EntryPoints.get() call in src/cleveragents/domain/contexts/scope_chain_resolver.py:63. The EntryPoints type does not have a .get() method; fixed by explicitly casting to dict[str, list[Any]] before calling .get() in the legacy fallback branch.

All quality gates verified locally:

  • lint ✓
  • typecheck ✓
  • unit_tests ✓ (all parallel processes: 0 failed, 0 skipped)
