Repeatability
High
The transformation rules are fixed and structural: deduplicate on a key, fill nulls with a constant, convert timezones. This pipeline can be scripted once and rerun on any monthly export with no meaningful variation.
Ambiguity Tolerance
Medium
Most success criteria are crisp, but 'impute missing revenue as $0 where appropriate' introduces a judgment call — not all missing revenue may be true zeros versus data gaps. The user should clarify the rule before handing this off.
Data & Tool Availability
High
The input is a flat CSV file the user already has; no live API access, credentials, or external systems are required. A code agent with file I/O and pandas or similar is fully equipped.
Error Cost
Medium
A bad deduplication or timestamp conversion would silently corrupt downstream cohort analysis, which could mislead business decisions. However, the original CSV is preserved and the output is reviewable before loading into the BI tool, making errors recoverable.
Human Judgment Required
Low
Once the tie-breaking rule for duplicate sessions and the revenue imputation condition are specified, every remaining step is deterministic logic with no taste, ethics, or relationship context involved.
