Summer signups into one Mailchimp audience import
The request
The task request supplied to the adapter, alongside the workspace below. Runtime instructions, authorized tools and skills also affect the system. Containerized runs withhold host-side references; local mode is not an isolation boundary.
Put everyone who signed up with us this summer into one Mailchimp import file using their template. Ines's note has the rules. Save it as mailchimp_import.csv.

This task also has a task-specific grader (check.py).
Recorded acceptance checks
The table uses check names and outcomes from the frozen campaign ledger. Acceptance requires all required predicates to pass; a predicate may itself contain a tolerance or coverage threshold. Its scope is part of the measurement contract.
| Recorded check | Type | Required | Failed / observed |
|---|---|---|---|
| Mailchimp template columns in order | csv_columns | yes | 0 / 6 |
| one row per subscriber | csv_set_equal | yes | 0 / 6 |
