Metadata

  • Commit message type: feat
  • Scope: plans
  • Branch name prefix: feat/v3.3.0-three-way-merge

Background and Context

As part of Epic #8491 (Three-Way Merge & Result Integration), subplan results must be merged back into the parent plan using a three-way merge strategy. Non-conflicting changes are combined automatically; conflicts are surfaced to the user.

This issue blocks Epic #8491.

Expected Behavior

  • When subplans complete, their results are merged back into the parent plan
  • Three-way merge: base (original), left (subplan A result), right (subplan B result)
  • Non-conflicting changes are combined automatically
  • Conflicting changes are identified and surfaced to the user for resolution

Acceptance Criteria

  • ThreeWayMerger class is implemented with base/left/right inputs
  • Non-conflicting changes are combined automatically
  • Conflicting changes are identified and returned as MergeConflict objects
  • Integration tests verify merge with non-conflicting and conflicting subplan results
  • Unit tests achieve >= 97% coverage

Subtasks

  • Design ThreeWayMerger interface and MergeConflict data structure
  • Implement three-way merge algorithm
  • Implement conflict detection and reporting
  • Integrate merger into subplan result collection
  • Write integration tests for merge scenarios
  • Write unit tests for merge algorithm

Definition of Done

  1. ThreeWayMerger is implemented and integrated
  2. Integration tests verify merge with conflicting and non-conflicting results
  3. Unit tests pass with >= 97% coverage
  4. Code reviewed and merged to main branch

[AUTO-OWNR-2] Triage Decision (Cycle 2)

Status: Verified

MoSCoW: Must Have
Priority: High
Milestone: v3.3.0

Rationale: This is a required implementation task for the v3.3.0 milestone (Subplan Orchestration & Plan Correction). The v3.3.0 acceptance criteria explicitly requires a three-way merge strategy to combine non-conflicting subplan results automatically while surfacing conflicts to the user.

Next Steps: Implementation worker should pick this up as part of the v3.3.0 epic work.
