decision engine components that drive AuditPipeline\nexecution:\n\n- PipelineHandler: orchestrates the full pipeline lifecycle\n(PENDING → ONGOING → SUCCEEDED/FAILED/CANCELLED), iterates stages\nin position order with cancellation checks between each, and\ndelegates CDM/cache management to the execution context.\n- CascadePipelineContext: executes each stage sequentially against\nthe CDM produced by the previous stage, simulating metric changes\nbetween stages so later strategies plan against the projected\ncluster state.\n- WeightedSchedulingMixin (planner/common.py): extracts the\nweight-based DAG scheduling logic shared by WeightPlanner and\nPipelinePlanner into a reusable mixin.\n- PipelinePlanner: merges solutions from all stages, optionally\ncollapses migration chains (A→B→C becomes A→C) and removes\ncircular round-trips (A→B then B→A), then schedules the merged\nactions using the weight-based DAG inherited from\nWeightedSchedulingMixin.\n- Wires the new handler into the decision engine RPC endpoint and\naudit messaging layer.\n- Adds unit tests for PipelineHandler, CascadePipelineContext and\nPipelinePlanner.\n\nPartially-implements: bp

decision engine components that drive AuditPipeline\nexecution:\n\n- PipelineHandler: orchestrates the full pipeline lifecycle\n(PENDING → ONGOING → SUCCEEDED/FAILED/CANCELLED), iterates stages\nin position order with cancellation checks between each, and\ndelegates CDM/cache management to the execution context.\n- CascadePipelineContext: executes each stage sequentially against\nthe CDM produced by the previous stage, simulating metric changes\nbetween stages so later strategies plan against the projected\ncluster state.\n- WeightedSchedulingMixin (planner/common.py): extracts the\nweight-based DAG scheduling logic shared by WeightPlanner and\nPipelinePlanner into a reusable mixin.\n- PipelinePlanner: merges solutions from all stages, optionally\ncollapses migration chains (A→B→C becomes A→C) and removes\ncircular round-trips (A→B then B→A), then schedules the merged\nactions using the weight-based DAG inherited from\nWeightedSchedulingMixin.\n- Wires the new handler into the decision engine RPC endpoint and\naudit messaging layer.\n- Adds unit tests for PipelineHandler, CascadePipelineContext and\nPipelinePlanner.\n\nPartially-implements: bp
