An audit found 102 FK columns with no index — every join, per-parent listing, and the delete cascades from _delete_cascade_policy scanned whole tables on them (deployments.app_id, audit_logs.user_id, dns_records.zone_id, webhook_logs.webhook_id, ...). All FK columns now declare index=True; migration 096 creates the same indexes on existing installs, deriving the list from the live schema at upgrade time (so it is idempotent and cannot drift from what an install actually has). Ratchet: test_every_fk_column_is_indexed pins the rule with no allowlist — a new FK column is born indexed or the build fails. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
