Bug Report

Feature Area: Context Assembly Pipeline — Plan Execution ACMS Integration

Severity: Critical (milestone-blocking — v3.4.0 deliverable #6: "Plan execution uses ACMS context; actor receives assembled fragments")

What Was Tested

Code-level analysis of src/cleveragents/a2a/facade.py and src/cleveragents/application/services/llm_actors.py against the specification's requirement that plan execution leverages ACMS context for LLM calls.

Expected Behavior (from spec §46851)

v3.4.0 deliverable #6: "Context assembly pipeline produces scoped context output for actors. Plan execution uses ACMS context; actor receives assembled fragments."

The ContextAssemblyPipeline should be invoked during plan execution to assemble context for LLM calls. The assembled context (fragments with UKO URIs, relevance scores, etc.) should be passed to the actor's LLM prompt.

Actual Behavior (from code)

In src/cleveragents/a2a/facade.py (line 471):

# TODO: Wire to ACMS ContextAssemblyPipeline once available.

This TODO comment indicates the A2A facade does not yet invoke the ACMS pipeline.

In src/cleveragents/application/services/llm_actors.py (line 325):

"execute_context_assembly_failed",

This log message suggests context assembly is attempted but may fail silently.

In src/cleveragents/application/services/execute_phase_context_assembler.py:
The ACMSExecutePhaseContextAssembler class exists and is wired to the plan execution pipeline. However, it uses ACMSPipeline() (the base class with default pass-through stubs) rather than ContextAssemblyPipeline (the production 10-stage pipeline with ConfidenceWeightedSelector, ProportionalBudgetAllocator, ParallelStrategyExecutor).

The ACMSPipeline base class uses DefaultStrategySelector, DefaultBudgetAllocator, and DefaultStrategyExecutor which are pass-through stubs, not the production implementations.

Code Location

src/cleveragents/a2a/facade.py line 471 (TODO comment)
src/cleveragents/application/services/execute_phase_context_assembler.py line 56 (self._pipeline = acms_pipeline or ACMSPipeline())
src/cleveragents/application/services/acms_pipeline.py — ContextAssemblyPipeline (production) vs ACMSPipeline (stub base class)

Impact

Plan execution uses stub ACMS pipeline instead of production ContextAssemblyPipeline
ConfidenceWeightedSelector, ProportionalBudgetAllocator, and ParallelStrategyExecutor are not used during plan execution
v3.4.0 deliverable #6 is not met
Actors receive context assembled by pass-through stubs, not by the real strategy pipeline

Fix Direction

ACMSExecutePhaseContextAssembler should be initialized with ContextAssemblyPipeline() instead of ACMSPipeline(). The DI container should inject the production pipeline.

Issue triaged by project owner:

State: Verified
Priority: High — ContextAssemblyPipeline not wired to plan execution is a v3.4.0 milestone deliverable gap. The A2A facade has a TODO comment instead of live ACMS integration. Actors receive stub context instead of real assembled fragments.
Milestone: v3.4.0 — This is explicitly listed as v3.4.0 deliverable #6: "Plan execution uses ACMS context; actor receives assembled fragments."
Story Points: 5 — L — Wiring the production ContextAssemblyPipeline into the DI container and replacing the stub ACMSPipeline() call, 1-2 days.
MoSCoW: MoSCoW/Must have — This is a v3.4.0 acceptance criterion. Without it, the ACMS pipeline is effectively dead code during plan execution.
Parent Epic: Needs linking to appropriate v3.4.0 ACMS Epic

This is a well-documented integration gap with clear evidence (TODO comment in facade.py). The fix direction is clear: inject ContextAssemblyPipeline() instead of ACMSPipeline() in the DI container.
