The migrator now slugifies each tag inside a nested @{} ref's filter list (cross-wildcard refs track the target's renamed registry entry — deterministic, same _slug the target applies), not just comma->or + null->!null. Idempotency-safe: the rewrite branch only fires on v1-shaped (comma/null) refs; v2 refs are left verbatim. Mirrored in src/manager/import-export/migrations.ts.
tests/test_sp1_smoke.py: end-to-end SP1 acceptance — a v1 library payload migrates to v2 (registry + option tags slugified, nested ref comma->or + slug + !null, instance category_filter list->expr + exclude_null), the migrated payload validates, and the boolean pool matcher resolves over the new multi-tag option shape.
