# Deregister Arn

`DELETE /api/v1/block/arns/{arn_id}`

Deregister a registered ARN: soft-delete the row (status='revoked') and
enqueue the matching S3 revoke. A sample ARN is stripped from every entitled
sample bucket; a block ARN from its one resolved SKU bucket (mirrors how each
was granted). Unconditional — this is a deliberate client removal, not the
legacy-backfill restriction hook, so it is not gated by any enforcement flag.
