Repeatability
High
The transformation rules are structurally identical every run: dedup by user+day, normalize strings, flag nulls. This is a deterministic pipeline that can be scripted and rerun on new exports without modification.
Ambiguity Tolerance
Medium
Deduplication and null-flagging criteria are crisp, but referrer consolidation requires judgment calls on which variants map to which canonical label — a fuzzy-matching step that may produce a few wrong groupings without human review of the mapping table.
Data & Tool Availability
High
The user has the CSV ready to hand off, and the task requires only standard data tools (Python/pandas or SQL) that any capable agent environment provides. No external APIs or credentials are needed.
Error Cost
Low
The original CSV is untouched, so any mistake in the output is fully reversible. A bad dedup or wrong referrer mapping is caught at dashboard QA before any decision is made, and the fix is a re-run.
Human Judgment Required
Low
The logic is mechanical: string normalization, groupby dedup, and null checks require no taste or intuition. A human should spot-check the referrer mapping table, but the heavy lifting is pure data transformation.
