A term did not pass validation

Error message

A term did not pass validation (term: #{term_id} / #{name}, error: #{term.errors.full_messages.join(", ")})

What it means

Persistence failure in TermImporter::Work#add_term: the enrollment term record was built and populated but ActiveRecord save returned false (model-level validation failures such as invalid dates or missing name). The error aggregates term.errors.full_messages, and the term is not counted or rolled into batch data.

Solutions

1. Read the embedded validation errors (e.g. bad dates) and fix the row
2. Re-run the SIS batch after correction
