Summary

Implements spec-compliant agents plan diff --correction <CORRECTION_ATTEMPT_ID> output. Fixes all issues identified in the cycle-1, cycle-2, and cycle-3 reviews.

Branch Note (M1)

The canonical CONTRIBUTING.md branch name is bugfix/m4-plan-diff-correction-stub. Because Forgejo's API does not support changing a PR's head branch after creation, both fix/plan-diff-correction-stub (PR head) and bugfix/m4-plan-diff-correction-stub are kept in sync via force-push. Both branches point to the same commit SHA.

Changes — Cycle 1 (C1–C8, M3–M8, m1–m3, n1)

C1/M1: Use unit_of_work.transaction() context manager — eliminates AttributeError crash and session resource leak.
C2: Wire unit_of_work via container.unit_of_work() in _get_apply_service().
C3: Three-section structured diff: Correction Diff summary, Comparison table, Patch Preview.
C4: Add features/plan_correction_diff.feature with BDD scenarios.
C5: Update 3 existing BDD scenarios to mock new service path.
C6: Canonical branch bugfix/m4-plan-diff-correction-stub created and synced.
C7: Commit amended with body and ISSUES CLOSED: #9085 footer.
C8: Narrow except Exception to except CorrectionAttemptNotFoundError.
M3–M8: Robot Framework tests, type annotations, argument validation, style fixes.

Changes — Cycle 2 (M2–M11, m1–m5, n3–n4)

Major Fixes

M2: Remove get_container() fallback entirely from correction_diff(). Raise ValidationError("unit_of_work is required for correction_diff()") if None. No container-singleton access inside service methods (ADR-003).
M3: Move import json and import yaml from inline method bodies to top-level imports in plan_apply_service.py (CONTRIBUTING.md §imports).
M4: Move from typing import Literal, cast from inline plan_diff() body to top-level from typing import in plan.py; remove both duplicate inline imports.
M5: Change ValueError → ValidationError for empty-input guards in correction_diff(). ValidationError is a CleverAgentsError subclass; the CLI's except CleverAgentsError handler now correctly surfaces these errors.
M6: Change COMMANDS: dict[str, object] → dict[str, Callable[[], None]] with from collections.abc import Callable; remove # type: ignore[operator] comment.
M7: Fix return type annotation of _make_apply_service_with_mocked_uow from -> PlanApplyService to -> tuple[PlanApplyService, str].
M8: Add 7th BDD scenario — ownership mismatch error path ("attempt does not belong to plan").
M9: Add BDD scenarios verifying empty plan_id and empty correction_attempt_id inputs produce error output.
M10: Add YAML format test case to robot/plan_correction_diff.robot and _correction_diff_yaml helper.
M11: Add type annotations to _build_mock_svc in plan_correction_diff_steps.py.

Minor Fixes

m1: Blank lines between _render_correction_diff_rich() and # Service section are correct (2 blank lines).
m2: Rename files_changed/new_insertions/new_deletions → decisions_changed/decisions_added/decisions_reverted in comparison section.
m3: Add code comment in _build_correction_diff_dict noting the comparison section deviates from spec's file-level schema; reference follow-up in issue #9085.
m4: Add THEN step correction-diff the service was called with format "<fmt>" asserting correction_diff() was called with correct fmt arg for JSON and YAML format scenarios.
m5: Update stale docstring in step_new_cov_no_mocks to reflect that the correction branch now calls the service (no longer returns early).
n3: Add comment in _build_correction_diff_dict noting patch_preview never produces real diff hunks and referencing future enhancement in issue #9085.
n4: Add defensive comment on if attempt.original_decision_id: guard explaining the field is always non-empty but the check is retained as a safety net.

Changes — Cycle 3 (Review Fixes)

Major Fixes

M1: Add code comment in _build_correction_diff_dict() summary section documenting the deviation from spec's files_changed/new_insertions/new_deletions fields. All three spec deviation sections now have consistent documentation.
M2: Fix BDD tests for empty plan_id and empty correction_attempt_id scenarios — change mock from PlanError to ValidationError to match the real correction_diff() behavior. Update assertions to check for "Error:" prefix (not "Diff Error:").

Minor Fixes

m1: Replace self-referential #9085 references in code comments with generic "future follow-up issue" text.
m2: Add Robot Framework test case for unit_of_work is None guard — constructs PlanApplyService(unit_of_work=None) and asserts ValidationError is raised.
m3: Wrap get_plan() call in correction_diff() with try/except NotFoundError to convert to PlanError, ensuring consistent "Diff Error:" prefix in CLI output for all not-found conditions.
m4: Replace yaml.dump() with yaml.safe_dump() in both diff() and correction_diff() to prevent serialization of arbitrary Python objects.
m5: Add rich.markup.escape() on guidance and archived_artifacts_path fields in _render_correction_diff_rich() to prevent Rich markup injection.
m6: Add replacement assertion "orig-decision-001" in plan_commands_new_coverage.feature after the removed "plan-100" assertion.
m7: Add debug logging at correction_diff() entry and warning logging on ownership-check failure.

Nits

n1: Add -> PlanApplyService return type annotation to _get_apply_service() with TYPE_CHECKING import.
n2: Extract duplicate cast() expression in plan_diff() to a single _fmt variable before the if correction: branch.
n3: Change if correction_diff_side_effect: to if correction_diff_side_effect is not None: in _build_mock_svc.
n4: Fix Robot helper UoW mock to use idiomatic __enter__.return_value = mock_ctx instead of __enter__ = MagicMock(return_value=mock_ctx).
n5: Remove dead hasattr fallbacks on StrEnum fields (CorrectionMode.value and CorrectionAttemptState.value are always available).
n6: Add spec-defined success message at end of plain ([OK] Correction diff generated) and rich (✓ OK Correction diff generated) output.

Code Review Decision: REQUEST CHANGES

PR: fix(cli): implement plan diff --correction to show real correction attempt diff
Focus Area: Test Quality and Coverage (primary), plus correctness and architecture

⚠️ Note: Forgejo prevents self-review (PR author cannot approve/reject their own PR). This review is posted as a comment to preserve the findings.

✅ What Works Well

The stub is correctly removed and replaced with a real implementation
All four output formats (rich, plain, json, yaml) are supported
The plan ownership check (attempt.plan_id != plan_id) is a good security guard
The CLI wiring is clean and minimal
The _build_correction_diff_dict helper is well-structured
Commit message matches the required format exactly
PR closes the correct issue (#9085) with a closing keyword
Milestone (v3.3.0) and label (Type/Bug) are correctly set

❌ Blocking Issues

1. Missing BDD Scenarios (Critical — Required by Issue #9085)

The issue explicitly lists as a subtask:

Add BDD scenarios in features/plan_diff_artifacts.feature or a new feature file for the --correction path

The features/plan_diff_artifacts.feature file was not modified in this PR. There are no correction diff scenarios added anywhere. This is a required acceptance criterion and a Definition of Done item.

Required scenarios should include at minimum:

agents plan diff --correction <ID> <PLAN_ID> returns real diff (not stub)
Correction diff shows reverted/added decisions
Correction diff supports all output formats (rich, plain, json, yaml)
Error when correction attempt not found
Error when correction attempt does not belong to the plan

2. Overly Broad Exception Catch (Code Quality Violation)

In correction_diff() (plan_apply_service.py):

try:
    attempt = correction_repo.get(correction_attempt_id)
except Exception as e:
    raise PlanError(...) from e

The CONTRIBUTING.md standard prohibits bare except: and requires catching specific exceptions. This should catch the specific repository NotFoundError or equivalent, not the generic Exception. Catching Exception masks programming errors (e.g., AttributeError, TypeError) that should propagate.

3. Architecture Violation: Direct Container Access in Service Layer

The correction_diff method calls get_container() directly inside the service method:

from cleveragents.application.container import get_container
container = get_container()
unit_of_work = container.unit_of_work()
correction_repo = unit_of_work.correction_attempts

This violates the four-layer architecture. The correction attempt repository should be injected via the constructor (like _changeset_store and _checkpoint_manager are), not fetched from the global container at call time. This also makes the method untestable without mocking the global container.

4. Unit of Work Not Used as Context Manager

The unit of work is obtained but not used as a context manager:

unit_of_work = container.unit_of_work()
correction_repo = unit_of_work.correction_attempts

Typically, unit of work should be used with with container.unit_of_work() as uow: to ensure proper transaction management and cleanup.

⚠️ Non-Blocking Issues

5. Missing Input Validation

The correction_diff method does not validate its inputs. Following the pattern of cleanup_changeset (which validates plan_id), both plan_id and correction_attempt_id should be validated as non-empty strings at the start of the method.

6. Unused Variable

The plan variable returned from self._lifecycle.get_plan(plan_id) is assigned but never used after the existence check. Should be documented with a comment or assigned to _.

7. Missing Blank Line Separator

The correction_diff method is missing a blank line between the end of the diff method and its definition. Minor style issue but inconsistent with the rest of the file.

Summary

Category	Status
Stub removed	✅
All formats supported	✅
CLI wiring correct	✅
BDD scenarios added	❌ Missing
Specific exception handling	❌ Uses bare `Exception`
Architecture (DI)	❌ Direct container access
Unit of work usage	❌ Not used as context manager
Input validation	⚠️ Missing
Test coverage >= 97%	❓ Cannot verify without BDD tests

The core functionality is implemented correctly, but the missing BDD tests, overly broad exception handling, and architecture violation (direct container access) must be addressed before merging.

Summary

Reviewed the new correction diff plumbing.
Identified a blocking issue that keeps the "--correction" flag from working.

Issues

agents plan diff --correction still prints the equivalent of the old stub panel instead of calling the new PlanApplyService.correction_diff() implementation. In src/cleveragents/cli/commands/plan.py (see the plan_diff handler around lines 3288-3310) the code continues to short-circuit with the placeholder Panel. As a result, the CLI never reaches the new service logic, so the feature remains non-functional.

Additional Observations

The PR description mentions new BDD scenarios, but none were added in this diff.

Code Review: APPROVED ✅

PR: fix(cli): implement plan diff --correction to show real correction attempt diff
Review Focus: api-consistency, naming-conventions, code-patterns
Cycle: 3 (addresses all Cycle 1 + Cycle 2 blocking issues)

✅ All Blocking Issues from Previous Cycles — Resolved

1. Missing BDD Scenarios — ✅ RESOLVED

A dedicated features/plan_correction_diff.feature file was added with 9 scenarios covering all 4 output formats (rich, plain, json, yaml) and 5 error paths (plan not found, correction not found, ownership mismatch, empty plan_id, empty correction_attempt_id). Three existing BDD scenarios in plan_cli_commands_r2.feature, plan_cli_uncovered_region_coverage.feature, and plan_commands_new_coverage.feature were updated to mock the new service path. Full step definitions in features/steps/plan_correction_diff_steps.py (183 lines).

2. Overly Broad Exception Catch — ✅ RESOLVED

Now catches CorrectionAttemptNotFoundError specifically (imported from cleveragents.infrastructure.database.repositories). No bare except Exception remains.

3. Architecture Violation (Direct Container Access) — ✅ RESOLVED

_get_apply_service() in plan.py now calls container.unit_of_work() and passes it to PlanApplyService(lifecycle_service=lifecycle, unit_of_work=container.unit_of_work()). The correction_diff() method no longer calls get_container() — it uses self._unit_of_work exclusively. Raises ValidationError("unit_of_work is required for correction_diff()") if None (ADR-003 compliant).

4. Unit of Work Not Used as Context Manager — ✅ RESOLVED

Uses with uow.transaction() as ctx: correctly, ensuring proper transaction management and resource cleanup.

5–7. Non-Blocking Issues — ✅ ALL RESOLVED

Input validation: if not plan_id / if not correction_attempt_id guards added with ValidationError
Unused variable: self._lifecycle.get_plan(plan_id) called without assignment (existence check only)
Blank lines: Correct 2-blank-line separation between methods

✅ Review Focus Areas

API Consistency

correction_diff(plan_id, correction_attempt_id, fmt="rich") mirrors diff(plan_id, fmt="rich") — consistent signature shape ✅
fmt: Literal["rich", "plain", "json", "yaml"] — consistent type annotation with diff() ✅
ValidationError for input guards, PlanError for domain errors — consistent with service-layer conventions ✅
_get_apply_service() DI pattern consistent with other service factories ✅

Naming Conventions

_build_correction_diff_dict — mirrors _build_artifacts_dict naming pattern ✅
_render_correction_diff_plain / _render_correction_diff_rich — mirrors _render_diff_plain / _render_diff_rich ✅
decisions_changed, decisions_added, decisions_reverted — domain-appropriate renaming from the file-level files_changed/new_insertions/new_deletions stub names ✅
Step prefix correction-diff — consistent with other step file prefix conventions ✅
_PATCH_GET_APPLY_R2 constant — consistent with existing _PATCH_GET_APPLY pattern ✅

Code Patterns

cast(Literal[...], fmt if fmt in (...) else "rich") used for type-safe format coercion — valid and consistent ✅
_build_mock_svc helper in step definitions — good DRY pattern ✅
COMMANDS: dict[str, Callable[[], None]] — correct type annotation replacing dict[str, object] ✅
from __future__ import annotations at top of all new files ✅
use_step_matcher("re") / use_step_matcher("parse") switching — correct Behave pattern for mixed matchers ✅
Robot Framework helper uses yaml.safe_load() for YAML parsing — correct ✅

Summary

This is a well-executed Cycle 2 fix that fully addresses every blocking and non-blocking issue raised in the previous review rounds. The implementation is correct, the architecture is clean (proper DI, no container singleton in service layer), exception handling is specific, the UoW is used as a context manager, and the test suite is comprehensive (BDD + Robot Framework, all 4 formats, all error paths). Coverage at 97.1% meets the 97% threshold.

Approved for merge.

## Code Review: APPROVED ✅ **PR:** fix(cli): implement plan diff --correction to show real correction attempt diff **Review Focus:** api-consistency, naming-conventions, code-patterns **Cycle:** 3 (addresses all Cycle 1 + Cycle 2 blocking issues) --- ### ✅ All Blocking Issues from Previous Cycles — Resolved #### 1. Missing BDD Scenarios — ✅ RESOLVED A dedicated `features/plan_correction_diff.feature` file was added with **9 scenarios** covering all 4 output formats (rich, plain, json, yaml) and 5 error paths (plan not found, correction not found, ownership mismatch, empty plan_id, empty correction_attempt_id). Three existing BDD scenarios in `plan_cli_commands_r2.feature`, `plan_cli_uncovered_region_coverage.feature`, and `plan_commands_new_coverage.feature` were updated to mock the new service path. Full step definitions in `features/steps/plan_correction_diff_steps.py` (183 lines). #### 2. Overly Broad Exception Catch — ✅ RESOLVED Now catches `CorrectionAttemptNotFoundError` specifically (imported from `cleveragents.infrastructure.database.repositories`). No bare `except Exception` remains. #### 3. Architecture Violation (Direct Container Access) — ✅ RESOLVED `_get_apply_service()` in `plan.py` now calls `container.unit_of_work()` and passes it to `PlanApplyService(lifecycle_service=lifecycle, unit_of_work=container.unit_of_work())`. The `correction_diff()` method no longer calls `get_container()` — it uses `self._unit_of_work` exclusively. Raises `ValidationError("unit_of_work is required for correction_diff()")` if None (ADR-003 compliant). #### 4. Unit of Work Not Used as Context Manager — ✅ RESOLVED Uses `with uow.transaction() as ctx:` correctly, ensuring proper transaction management and resource cleanup. #### 5–7. Non-Blocking Issues — ✅ ALL RESOLVED - Input validation: `if not plan_id` / `if not correction_attempt_id` guards added with `ValidationError` - Unused variable: `self._lifecycle.get_plan(plan_id)` called without assignment (existence check only) - Blank lines: Correct 2-blank-line separation between methods --- ### ✅ Review Focus Areas #### API Consistency - `correction_diff(plan_id, correction_attempt_id, fmt="rich")` mirrors `diff(plan_id, fmt="rich")` — consistent signature shape ✅ - `fmt: Literal["rich", "plain", "json", "yaml"]` — consistent type annotation with `diff()` ✅ - `ValidationError` for input guards, `PlanError` for domain errors — consistent with service-layer conventions ✅ - `_get_apply_service()` DI pattern consistent with other service factories ✅ #### Naming Conventions - `_build_correction_diff_dict` — mirrors `_build_artifacts_dict` naming pattern ✅ - `_render_correction_diff_plain` / `_render_correction_diff_rich` — mirrors `_render_diff_plain` / `_render_diff_rich` ✅ - `decisions_changed`, `decisions_added`, `decisions_reverted` — domain-appropriate renaming from the file-level `files_changed`/`new_insertions`/`new_deletions` stub names ✅ - Step prefix `correction-diff` — consistent with other step file prefix conventions ✅ - `_PATCH_GET_APPLY_R2` constant — consistent with existing `_PATCH_GET_APPLY` pattern ✅ #### Code Patterns - `cast(Literal[...], fmt if fmt in (...) else "rich")` used for type-safe format coercion — valid and consistent ✅ - `_build_mock_svc` helper in step definitions — good DRY pattern ✅ - `COMMANDS: dict[str, Callable[[], None]]` — correct type annotation replacing `dict[str, object]` ✅ - `from __future__ import annotations` at top of all new files ✅ - `use_step_matcher("re")` / `use_step_matcher("parse")` switching — correct Behave pattern for mixed matchers ✅ - Robot Framework helper uses `yaml.safe_load()` for YAML parsing — correct ✅ --- ### ✅ PR Criteria Checklist (12/12) | Criterion | Status | |---|---| | Conventional commit title | ✅ `fix(cli): implement plan diff --correction to show real correction attempt diff` | | Closing keyword | ✅ `Closes #9085` | | Milestone | ✅ v3.3.0 | | Type label | ✅ `Type/Bug` | | State label | ✅ `State/In Review` | | PR description quality | ✅ Summary, Branch Note, Changes by cycle, Quality Gates | | Branch name (canonical) | ✅ `bugfix/m4-plan-diff-correction-stub` (synced; Forgejo limitation noted) | | Quality gates self-reported | ✅ lint, typecheck, unit_tests (15050 scenarios), coverage 97.1% | | Commit message matches issue Metadata | ✅ Exact match | | BDD unit tests (Behave) | ✅ 9 new scenarios + 3 updated | | Integration tests (Robot Framework) | ✅ `robot/plan_correction_diff.robot` + helper | | Mergeable | ✅ No conflicts | --- ### Summary This is a well-executed Cycle 2 fix that fully addresses every blocking and non-blocking issue raised in the previous review rounds.
