From 77ba5091d1b661376b2a28176a5c0578cee55832 Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Wed, 15 Apr 2026 00:40:58 +0000 Subject: [PATCH 1/7] feat(plans): implement conflict detection and structured conflict report for three-way merge - Add ConflictType enum for categorizing conflict types - Add ConflictContext dataclass for storing conflict information - Add ConflictReport dataclass for structured conflict reporting - Add ConflictResolution enum for resolution strategies - Implement ThreeWayMergeConflictDetector with standard three-way merge algorithm - Add automatic conflict resolution heuristics - Add comprehensive BDD test suite with 20+ test scenarios - Update CHANGELOG.md with new feature documentation --- .../plan_merge_conflict_detection.feature | 158 ++++++++

uncovered branches in merge_conflict with BDD scenarios and pragmas Add 4 BDD scenarios to features/plan_merge_conflict_detection.feature: - No conflict when all three versions have identical values (covers line 269 in _detect_field_conflict: neither-side-changed early return) - Cannot add conflict with empty field path (covers line 121 ValueError) - Resolve conflict using merged version (covers lines 148-149 MERGED branch in get_resolved_value) - Get resolved value with manual resolution raises error (covers line 150 MANUAL -> ValueError in get_resolved_value) Add corresponding step 'I try to add a conflict with empty field path' to the step definitions. Mark genuinely dead-code branches with # pragma: no cover: - Line 74: resolved_value guard (context/conflict_type None) -- unreachable through detect() since _analyse_field always sets both - Line 141: get_resolved_value conflict-not-found guard -- unreachable through public API since resolve_conflict() pre-checks existence - Lines 280-281: DELETE_DELETE in _detect_field_conflict -- unreachable because None==None is caught by the prior parent_val==subplan_val guard - Line 304: auto_resolve_conflicts DELETE_DELETE continue -- unreachable since detect_conflicts() can never produce DELETE_DELETE conflicts - Line 331: detect_diff_text context-is-None guard -- unreachable since _analyse_field always sets context - Lines 405-410: _analyse_field not-changed/not-changed branch -- unreachable because detect() fast-paths the all-equal case before calling _analyse_field Also expand test_merge_conflict_legacy_contract.py with 7 pytest-style tests covering the same edge cases
