Resolve all 8 blocking issues from review #8083: 1. File size limits: Split engine into three_way_merge_engine.py + three_way_merge_models.py, split step definitions into given/when/ then files — all under 500-line limit. 2. Duplicate @given decorators: Removed duplicate 'no subplan recorded' path, consolidated into single handler in given_steps.py. 3. Missing _subplan_costs_map initialization: Added in step_no_subplan_costs to prevent AttributeError. 4. Robot Framework tests: Added robot/three_way_merge_engine.robot with 8 integration test cases and helper_three_way_merge_engine.py. 5. Dead code removal: Removed unused _propagate_error() method (error propagation handled inline in merge()). 6. Dead placeholder code: Removed _update_timestamps() with pass body. 7. Sequential merge invocation: Implemented actual two-phase engine calls in step_sequential_merge (Was just setting a flag). 8. Typo fix: priorites -> priorities in _state_priority(). ISSUES CLOSED: #9557
