Resuming a Long-Paused Data Pipeline Task

Problem Description

A data engineering team had an urgent all-hands situation last week and had to abandon a multi-day Airflow pipeline refactoring effort mid-stream. The engineer who was leading the work created a handoff document just before stepping away, but that was several days ago. Now the team is trying to figure out whether they can safely pick up where they left off, or whether the handoff needs to be refreshed first.

The team lead has asked for a written assessment of the handoff's current state. The pipeline touches production data and the team can't afford to resume based on stale context — they need confidence that the documented state still reflects reality before anyone starts making changes.

Output Specification

Write your assessment to a file named resume-assessment.md. The team lead needs to know whether the handoff is safe to resume from, and if not, what needs to happen before work can start again.
