  • Commit Message: fix(subplan): persist child Plan objects in SubplanService.spawn() to start subplan lifecycle
  • Branch: fix/subplan-spawn-child-plans-not-persisted

Background and Context

Feature Area: Subplans & Parallel Execution
Spec Reference: Spec §Plan Lifecycle: "Plans must spawn child plans (subplans) during execution." Spec §Decision: "subplan_spawn — Decision to create a child plan." TDD issue #4289 (tdd_subplan_spawn_orchestration.feature) captures this as a known gap.

When SubplanService.spawn() creates child Plan domain objects, those objects must be persisted to the plan repository so that their lifecycle (Strategize → Execute → Apply) can proceed. Currently, child plans are created in memory but never saved — their lifecycle never starts.

Expected Behavior

SubplanService.spawn() creates child Plan domain objects and persists them via PlanLifecycleService before SubplanExecutionService.execute_all() is called. After agents plan execute <PARENT_PLAN_ID>:

  • agents plan list shows child plans.
  • agents plan tree <PARENT_PLAN_ID> shows child plan nodes.
  • Child plans transition through their lifecycle phases (Strategize → Execute → Apply).

Actual Behavior

SubplanService.spawn() creates Plan domain objects in memory (stored in SpawnResult.child_plans) but never persists them. PlanExecutor._spawn_subplans() calls SubplanService.spawn() and discards spawn_result.child_plans entirely — it only uses spawn_result.spawned_statuses. The child plans are never saved to the database, never transition through their lifecycle phases, and SubplanExecutionService.execute_all() receives only SubplanStatus stubs with no backing plan records.

Steps to Reproduce:

  1. Create a parent plan with a subplan_spawn decision recorded during Strategize.
  2. Run agents plan execute <PARENT_PLAN_ID>.
  3. Run agents plan list — observe no child plans appear.
  4. Run agents plan tree <PARENT_PLAN_ID> — observe no child plan nodes.

Source Evidence:

  • src/cleveragents/application/services/subplan_service.py lines ~255-290: child_plans list is populated but spawn() has no plan_repository or lifecycle_service dependency to persist them.
  • src/cleveragents/application/services/plan_executor.py _spawn_subplans() method: spawn_result.child_plans is never used after spawn() returns.
  • features/tdd_subplan_spawn_orchestration.feature: TDD issue #4289 explicitly documents this gap with @tdd_expected_fail scenarios.

Acceptance Criteria

  • SubplanService.spawn() accepts a PlanLifecycleService (or PlanRepository) dependency and persists each child Plan object before returning.
  • PlanExecutor._spawn_subplans() uses spawn_result.child_plans to confirm persistence, not just spawned_statuses.
  • After agents plan execute <PARENT_PLAN_ID>, agents plan list shows all spawned child plans.
  • After agents plan execute <PARENT_PLAN_ID>, agents plan tree <PARENT_PLAN_ID> shows child plan nodes with correct parent-child relationships.
  • Child plans transition through their lifecycle phases (Strategize → Execute → Apply) after being persisted.
  • The @tdd_expected_fail scenarios in features/tdd_subplan_spawn_orchestration.feature are promoted to passing scenarios once the fix is applied.

Subtasks

  • Add plan_repository or lifecycle_service dependency to SubplanService.
  • Update SubplanService.spawn() to persist each child Plan via the repository/lifecycle service before returning SpawnResult.
  • Update PlanExecutor._spawn_subplans() to verify child plans are persisted (use spawn_result.child_plans).
  • Add integration test asserting child plans appear in plan list and plan tree after plan execute.
  • Promote @tdd_expected_fail scenarios in features/tdd_subplan_spawn_orchestration.feature to passing once fix is applied.
  • Update DI container wiring to inject the new dependency into SubplanService.

Definition of Done

This issue is closed when:

  • Child plans spawned by SubplanService.spawn() are persisted to the database.
  • agents plan list and agents plan tree show child plans after parent plan execution.
  • Child plans transition through their lifecycle phases.
  • All @tdd_expected_fail scenarios in features/tdd_subplan_spawn_orchestration.feature pass.
  • All new and existing tests pass in CI.

HAL9000 added this to the v3.3.0 milestone 2026-04-14 08:50:08 +00:00

Triage: Verified [AUTO-OWNR-1]

Critical bug: SubplanService.spawn() does not persist child Plan objects — the subplan lifecycle never starts. This means subplans are never actually created or tracked, making the entire subplan feature non-functional.

Assigning to v3.3.0 (Corrections + Subplans + Checkpoints). Priority High — subplans are never persisted, making the feature completely non-functional.

MoSCoW: Must Have — subplan persistence is the foundation of the subplan feature. Without it, no subplan functionality works.
