//
// One-shot backfill of ysterbaard_companies.client_status from existing
// is_client (bool) + enterprise_status (text) values.
//
// Rules (added 2026-08-20):
//   is_client=true  AND enterprise_status contains "Deregistered" -> "deregistered"
//   is_client=true                                          else -> "active_client"
//   is_client=false AND enterprise_status contains "In Process" -> "non_client"
//   is_client=false                                        else -> "non_client"
//
// Dormant clients are a manual judgement call — this script does NOT
// set anyone to dormant_client. Operators must toggle dormant manually.
//
// Idempotent: re-running overwrites previous values with the same derivation.
