Summary

ACMSExecutePhaseContextAssembler.__init__() creates a bare ACMSPipeline() as its default pipeline when no pipeline is injected. This means plan execution context assembly always uses the base pipeline with DefaultStrategySelector, DefaultBudgetAllocator, and DefaultStrategyExecutor (sequential, no parallelism, no circuit breaking) instead of the production ContextAssemblyPipeline with ConfidenceWeightedSelector, ProportionalBudgetAllocator, and ParallelStrategyExecutor.

Evidence

In src/cleveragents/application/services/execute_phase_context_assembler.py:

class ACMSExecutePhaseContextAssembler(ExecutePhaseContextAssembler):
    def __init__(
        self,
        context_tier_service: Any,
        project_repository: NamespacedProjectRepository,
        acms_pipeline: ACMSPipeline | None = None,
        hot_max_tokens: int = 4096,
    ) -> None:
        ...
        self._pipeline = acms_pipeline or ACMSPipeline()  # ← base class, not ContextAssemblyPipeline

In src/cleveragents/cli/commands/plan.py (line ~1704):

context_assembler = ACMSExecutePhaseContextAssembler(
    context_tier_service=container.context_tier_service(),
    ...
    # No acms_pipeline= argument — falls back to ACMSPipeline()
)

The DI container wires acms_pipeline = providers.Singleton(ACMSPipeline, ...) (also base class per issue #4559), so even when the assembler receives the DI-wired pipeline, it is still the base class.

Impact

Plan execution context assembly never uses ConfidenceWeightedSelector (confidence-weighted strategy selection)
Plan execution context assembly never uses ProportionalBudgetAllocator (proportional budget distribution)
Plan execution context assembly never uses ParallelStrategyExecutor (concurrent strategy execution with timeouts and circuit breaking)
Spec requirement: "Plan execution leverages ACMS context for LLM calls" is partially met but uses degraded pipeline

Spec Reference

docs/specification.md §46896 (M5 acceptance criteria):

The context assembly pipeline produces scoped, budget-constrained context views for actors.

docs/specification.md §44924:

There are ten pluggable components, grouped into three pipeline phases

Steps to Reproduce

Inspect src/cleveragents/application/services/execute_phase_context_assembler.py
Note self._pipeline = acms_pipeline or ACMSPipeline() — base class used as default
Inspect src/cleveragents/cli/commands/plan.py around line 1704 — no acms_pipeline argument passed to ACMSExecutePhaseContextAssembler

Subtasks

Update ACMSExecutePhaseContextAssembler.__init__ to default to ContextAssemblyPipeline() instead of ACMSPipeline()
Update plan.py to pass container.acms_pipeline() to ACMSExecutePhaseContextAssembler
Add test verifying production pipeline is used during plan execution context assembly

Definition of Done

ACMSExecutePhaseContextAssembler defaults to ContextAssemblyPipeline when no pipeline is injected
Plan execution context assembly uses ParallelStrategyExecutor with circuit breaking
Existing tests pass; new test added for production pipeline wiring

## Summary `ACMSExecutePhaseContextAssembler.__init__()` creates a bare `ACMSPipeline()` as its default pipeline when no pipeline is injected. This means plan execution context assembly always uses the base pipeline with `DefaultStrategySelector`, `DefaultBudgetAllocator`, and `DefaultStrategyExecutor` (sequential, no parallelism, no circuit breaking) instead of the production `ContextAssemblyPipeline` with `ConfidenceWeightedSelector`, `ProportionalBudgetAllocator`, and `ParallelStrategyExecutor`. ## Evidence In `src/cleveragents/application/services/execute_phase_context_assembler.py`: ```python class ACMSExecutePhaseContextAssembler(ExecutePhaseContextAssembler): def __init__( self, context_tier_service: Any, project_repository: NamespacedProjectRepository, acms_pipeline: ACMSPipeline | None = None, hot_max_tokens: int = 4096, ) -> None: ... self._pipeline = acms_pipeline or ACMSPipeline() # ← base class, not ContextAssemblyPipeline ``` In `src/cleveragents/cli/commands/plan.py` (line ~1704): ```python context_assembler = ACMSExecutePhaseContextAssembler( context_tier_service=container.context_tier_service(), ... # No acms_pipeline= argument — falls back to ACMSPipeline() ) ``` The DI container wires `acms_pipeline = providers.Singleton(ACMSPipeline, ...)` (also base class per issue #4559), so even when the assembler receives the DI-wired pipeline, it is still the base class. ## Impact - Plan execution context assembly never uses `ConfidenceWeightedSelector` (confidence-weighted strategy selection) - Plan execution context assembly never uses `ProportionalBudgetAllocator` (proportional budget distribution) - Plan execution context assembly never uses `ParallelStrategyExecutor` (concurrent strategy execution with timeouts and circuit breaking) - Spec requirement: "Plan execution leverages ACMS context for LLM calls" is partially met but uses degraded pipeline ## Spec Reference `docs/specification.md` §46896 (M5 acceptance criteria): > The context assembly pipeline produces scoped, budget-constrained context views for actors. `docs/specification.md` §44924: > There are ten pluggable components, grouped into three pipeline phases ## Steps to Reproduce 1.

✅ Triage: Verified [AUTO-OWNR-1]

Valid bug: ACMSExecutePhaseContextAssembler defaults to the base ACMSPipeline instead of the production ContextAssemblyPipeline, causing Phase 1 components to be bypassed during plan execution context assembly. This is a real functional defect in the ACMS pipeline.

Assigning to v3.4.0 (ACMS v1 + Context Scaling) as this is core ACMS pipeline wiring. Priority Medium — the system functions but uses a degraded pipeline.

MoSCoW: Should Have — correct pipeline wiring is important for ACMS correctness but the system remains operational.
