Repeatability
High
The operations — deduplication by session ID, URL normalization, missing-value handling — are structurally identical every time this data arrives. This is a textbook repeatable ETL pattern.
Ambiguity Tolerance
High
Success criteria are concrete and verifiable: zero duplicate session IDs, consistent URL format, no silent missing values. A script can assert all three conditions programmatically.
Data & Tool Availability
High
The user has the CSV in hand and the task requires only standard data tools (Python/pandas or similar). No external APIs, live credentials, or third-party access are needed.
Error Cost
Medium
Errors could silently corrupt client-facing reports, which is a real business risk. However, the raw CSV is preserved and the transformation is fully reversible — a human spot-check before delivery mitigates this adequately.
Human Judgment Required
Low
Imputation strategy (e.g., median fill vs. flagging) is a minor decision the user can specify upfront. No taste, ethics, or relationship context is needed to execute the cleaning logic.
