  "message": "polygerrit-ui: improve flow email validation UX and contextual error handling\n\nThis change resolves b/537010867 by introducing client-side email account validation during flow creation, suppressing disruptive global error dialogs, and providing inline feedback.\n\nProduct \u0026 Technical Decisions:\n\n1. Debouncing Keystroke Lookups:\n   - Debounced stage parsing (\u0027parseStagesFromRawFlow\u0027) by 300ms during raw flow editing to avoid hammering the backend \u0027getAccountDetails\u0027 REST API on every keystroke.\n\n2. Contextual In-Modal Error Banners:\n   - Suppressed PolyGerrit\u0027s global 404 error toasts/dialogs during account lookups by passing a no-op error handler (\u0027errFn\u0027).\n   - Replaced global error popups with a contextual \u0027.error-banner\u0027 inside the modal itself, keeping the error state local to the authoring UI.\n\n3. Live Preview Error Display:\n   - Updated \u0027\u003cgr-flow-rule\u003e\u0027 parameter rendering to detect non-existent or invalid user IDs / email addresses and render an error state directly on the parameter chip in the live preview using \u0027EMAIL_PATTERN\u0027.\n\n4. Synchronous Flush on Submission:\n   - On clicking \"Create Flow\", any pending debounced parsing task is flushed synchronously (\u0027parseStagesDebounced.flush()\u0027), guaranteeing that inputs are validated immediately prior to dispatching the request.\n\nScreenshots:\n\nError preview chip: https://screenshot-v2.corp.google.com/1vefvmslk6og0\nFailure banner on attempted \u0027create flow\u0027: https://screenshot-v2.corp.google.com/174o5jb3kaepo\nSuccess on valid userId: https://screenshot-v2.corp.google.com/74uk8q4itf86o\n\nRelease-Notes: Added client-side email validation and in-modal error handling when creating change flows in PolyGerrit UI.\nTAG\u003dagy\nGoogle-Bug-Id: b/537010867\nBUG\u003d537010867\nCONV\u003d92d49428-aab5-4177-b1d2-6dc20cfe445a\nChange-Id: I55af56aaf9e5365564259757c6068c8d4b975bd2",
