build_first_run_pipeline now constructs epc_prediction=EpcPrediction() and accepts
comparables_repo + prediction_attributes_reader as optional params, threading them
into IngestionOrchestrator (ADR-0031). The on-switch is now just supplying those
two arguments — no orchestrator/handler edits — once they exist: the cohort repo
(its EPC client is the source client pending #1136) and the property_overrides
attributes reader (built separately). Both default None, so the feature stays OFF
and ingestion is unchanged until they're passed.
The epc_property.source migration is live, so the predicted-EPC persistence slot
(slice-5c) now works against the real DB. Handover updated to reflect the simpler
composition-root step.
pyright strict clean; handler + pipeline + ingestion-prediction tests pass.

The gap-fill is wired end-to-end (slices 5a-5e) behind seams; this note is what's
left to switch it on in production: (1) implement the PredictionTargetAttributesReader
stub over property_overrides — with the override-value → API-code mapping
select_comparables needs; (2) run the epc_property.source Drizzle migration; (3)
pass the three optional collaborators at the IngestionOrchestrator composition
root. Plus the open Validation-Cohort exclusion (no code path exists yet — exclude
on source_path == "predicted" when one is built) and the anomaly dual-use pointer.
No code change: the validation exclusion has no consumer to attach to today, and
the structural signal (source_path == "predicted") already exists from slice-5a.
