   ⛔ Not a claim, ⛔ not a dispatch.

   • p2: the list-view inspector's "Add filter" adds no row, so no list-view filter can be authored in Studio. Fix the row add, and pin a filter round-trip. From the studio-qa-2026-10-27 batch. Re-check the landing site on current main.

   Clause-②: no
   Metadata-protocol: none
   Responsibility: the Studio list-view inspector's filter builder (app-shell, this lane) drops the blank row "Add filter" inserts · the platform path that may cover it: a filter written by API, which works · reached by every builder filtering a list view in Studio
