Metadata

  • Commit message type: feat
  • Scope: a2a
  • Branch name prefix: feat/v3.5.0-a2a-hierarchical-decomposition

Background and Context

As part of Epic #8423 (A2A Protocol Integration) and the v3.5.0 Autonomy Hardening milestone, the system must support hierarchical plan decomposition with 4+ levels of subplans. This enables complex autonomous tasks to be broken down into manageable subtasks that execute in parallel.

This issue blocks Epic #8423.

Expected Behavior

  • A plan can spawn child subplans during execution
  • Subplans can themselves spawn child subplans (4+ levels deep)
  • Each level of the hierarchy is tracked and managed independently
  • The parent plan tracks the status of all child subplans
  • Hierarchical decomposition is triggered automatically based on task complexity

Acceptance Criteria

  • Plans can spawn child subplans during execution (at least 4 levels deep)
  • Each subplan has a parent reference and level indicator
  • Parent plan tracks status of all child subplans
  • Hierarchical decomposition is triggered by task complexity analysis
  • Integration tests verify 4+ level decomposition with a complex task
  • Unit tests achieve >= 97% coverage for decomposition logic

Subtasks

  • Implement subplan spawning mechanism (parent creates child plan)
  • Add parent reference and level tracking to Plan model
  • Implement task complexity analysis for decomposition triggering
  • Implement parent plan status tracking for child subplans
  • Write integration tests for 4+ level decomposition
  • Write unit tests for decomposition logic

Definition of Done

  1. Hierarchical plan decomposition works with 4+ levels
  2. Integration tests verify 4+ level decomposition
  3. Unit tests pass with >= 97% coverage
  4. Code reviewed and merged to main branch

[AUTO-OWNR-4] Triage Decision (Cycle 2)

Status: Verified

MoSCoW: Must Have
Priority: Critical
Milestone: v3.5.0

Rationale: This is a required implementation task for the v3.5.0 milestone (Autonomy Hardening). Hierarchical plan decomposition with 4+ levels is the core autonomy hardening feature — it is the primary goal of the v3.5.0 milestone and is explicitly listed in both the acceptance criteria and technical criteria. Elevated to Critical priority accordingly.

Next Steps: Implementation worker should pick this up as part of the v3.5.0 epic work.
