+-- Two FK constraints that are part of devtron OSS's baseline schema
+-- (devtron/scripts/sql/1_insert.up.sql) but were found missing on at least one real
+-- installation during db-housekeeping testing (devtron-services-enterprise PR #443).
+-- db-housekeeping's database/schemaassert.go refuses to run (AssertSchema) when either
+-- is absent, since its cascade-delete logic depends on this exact FK graph.

+-- Wrapped in existence checks so this migration is a no-op on installations that already
+-- have these constraints (the common case) and only takes effect where they're missing.
+-- Both were verified safe to add on the affected cluster: zero rows violated either FK
+-- before adding it.
