Correct a term and re-mirror what follows it
What It Does
Staff correct a committed period while preserving its earlier recorded values. Affiliation trimming and linked-period updates follow the correction in the same transaction.
The Flow
When Something Fails
Refusal rolls back the correction and dependent writes. Successful correction can leave chapters starting at the former date when coverage moves earlier, omits minimum-count rechecking, and publishes no separate event for affiliation trimming.
Open Design Questions
Decide whether earlier starts should extend chapter spans and whether correction should revalidate cross-program exclusivity.
