   ⛔ Not a claim, ⛔ not a dispatch.

   • p2: "Add field value" adds no row, so an update action's patch cannot be authored in Studio and the published action is a no-op. Fix the row add, and pin a patch round-trip. From the studio-qa-2026-10-27 batch. Re-check the landing site on current main.

   Claim: PM loop round 1
   Session: session_01QsR2jTfvjNTaR29ehLk26T
   Account: zhuangjianguo
   Branch: claude/project-thread-infmae (platform-assigned card-thread branch; a card thread can push only its assigned branch, and the name carries no issue number, so this claim is the identity record)
   Worktree: objectstack-issue-26735 (bundled with #26734: same inspector, one PR naming both)
   Domain: domain:ui
   Seat: domain:ui#4
   File surface: ui/packages/app-shell/src/views/metadata-admin/inspectors/ActionDefaultInspector.tsx, studio namespace en.ts/zh.ts only if a label is new, tests beside, one root changeset; ⛔ packages/spec/**, server packages, any new key, a runtime fallback for a typeless action (stop on breach; explain in the report)
   Container & model: S, mode:thread, model: TIER_DEFAULT (dispatch-gates --tier: no path-derived mandate; reason: the maintainer's standing rule 「只认领不需要 fable 的卡」, 2026-10-27T10:39Z), effort: high
   Clause-②: no
   Metadata-protocol: none
   Responsibility: the Studio action inspector (ui app-shell, this lane) drops the blank row "Add field value" adds, so an update action's patch cannot be authored · the platform path that may cover it: none, commitPatch is the only writer · reached by every update-fields action made in Studio
   Thread-read: 6447193000
   Premise: holds (commitPatch (ActionDefaultInspector.tsx:682-686) skips every key whose trim is empty, and the button (:938) commits ['', ''] on origin/main e9e344a9 at 2026-10-27T18:58Z)
   Serial constraints cleared: PR #26827 (same file) merged 18:57Z; no open PR touches the surface (scan of the 80 most recently updated open PRs 2026-10-27T18:58Z)

   Dispatched at 2026-10-27T19:00Z to the card thread on that branch; the order lives in the thread's opening message.
