Metadata

Commit message: refactor(application): split oversized service and infrastructure files into focused modules
Branch name: feature/refactor-split-oversized-files

Background and Context

The CONTRIBUTING.md code style requirement states: "Files under 500 lines — break into focused modules if approaching limit." An automated architecture guard scan on 2026-04-18 identified multiple source files that dramatically exceed this limit, with the largest being over 12× the allowed size.

Files exceeding 500 lines:

File	Lines	Excess
`infrastructure/database/repositories.py`	6,086	12.2× limit
`cli/commands/plan.py`	4,582	9.2× limit
`application/services/plan_lifecycle_service.py`	2,741	5.5× limit
`application/services/correction_service.py`	1,255	2.5× limit
`application/services/plan_executor.py`	1,156	2.3× limit
`application/services/plan_apply_service.py`	1,115	2.2× limit
`application/services/acms_service.py`	1,029	2.1× limit
`application/services/decision_service.py`	999	2.0× limit
`application/services/context_service.py`	970	1.9× limit
`application/services/checkpoint_service.py`	907	1.8× limit
`application/container.py`	1,041	2.1× limit
`application/services/acms_pipeline.py`	766	1.5× limit
`application/services/llm_actors.py`	510	1.0× limit
`mcp/adapter.py`	787	1.6× limit
`tool/runner.py`	544	1.1× limit
`a2a/facade.py`	626	1.3× limit

Current Behavior

Large monolithic files with multiple responsibilities violate the Single Responsibility Principle and the project's 500-line file size limit. For example:

repositories.py (6,086 lines) contains repository implementations for every domain entity (plans, actors, sessions, resources, tools, skills, decisions, checkpoints, etc.) in a single file
plan_lifecycle_service.py (2,741 lines) handles the entire plan lifecycle state machine in one file
cli/commands/plan.py (4,582 lines) contains all plan CLI commands in a single module

Expected Behavior

Each file should have a single, focused responsibility and stay under 500 lines. Large files should be split into cohesive sub-modules:

repositories.py → repositories/plan_repository.py, repositories/actor_repository.py, repositories/session_repository.py, repositories/resource_repository.py, etc.
plan_lifecycle_service.py → split by lifecycle phase (strategize, execute, apply, review) or by concern (state machine, event emission, persistence)
cli/commands/plan.py → split by command group (plan create/list/show, plan build/apply, plan correct/revert, etc.)

Acceptance Criteria

No file in src/cleveragents/ exceeds 500 lines
Each split module has a single, clearly named responsibility
All public APIs remain backward-compatible (no breaking changes to imports used by other modules)
All existing Behave scenarios continue to pass after splitting
Coverage remains ≥ 97%
nox -s typecheck passes with zero errors after splitting

Supporting Information

Scan date: 2026-04-18
Scan tool: Architecture Guard Worker (automated)
CONTRIBUTING.md rule: "Files under 500 lines — break into focused modules if approaching limit"
The repositories.py file is the most critical — at 6,086 lines it is also the source of 445 # type: ignore suppressions (see companion issue)
Splitting repositories.py should be coordinated with the type-safety refactor

Subtasks

Split infrastructure/database/repositories.py into per-entity repository modules under infrastructure/database/repositories/
Split application/services/plan_lifecycle_service.py into phase-focused sub-modules
Split cli/commands/plan.py into command-group sub-modules
Split application/container.py — extract wiring groups into focused sub-containers or factory functions
Split application/services/correction_service.py into focused sub-modules
Split application/services/plan_executor.py into focused sub-modules
Split application/services/plan_apply_service.py into focused sub-modules
Split application/services/acms_service.py into focused sub-modules
Update all import sites after each split
Tests (Behave): Verify all existing scenarios pass after each split
Verify coverage ≥ 97% via nox -s coverage_report after each split
Run nox (all default sessions), fix any errors

Definition of Done

This issue is complete when:

All subtasks above are completed and checked off.
No file in src/cleveragents/ exceeds 500 lines.
All existing tests pass and coverage remains ≥ 97%.
A Git commit is created where the first line matches the Commit Message in Metadata exactly, followed by a blank line, then additional details.
The commit is pushed to the branch matching the Branch in Metadata exactly.
The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done.
