@@ -79,3 +79,17 @@
 - Runtime source/build is 9adab45, Renderer index-Dn2S79es.js loaded from this checkout, document complete and React mounted. Startup guard blocked one show and retained a hidden, unfocused window until user activation. A 12-second NSWorkspace monitor recorded trialFocused=false and unchanged foreground PID 409. Installed production PID 23486 remains untouched.
 - Preserved the same trial user-data directory. Updated only local trial launch metadata after backing up prior descriptors. No cloud configuration publication, deliberate model request, history seeding or UI activation. This checkout must remain available while the trial uses its build.
 - Task-aware drift checker now flags the imported peer task record 20260928-agent-refresh-a6d109b3 relative to the original task base. It is a committed dependency imported by the authorized merge, verified byte-for-byte identical to 4f6bda4; no peer document was edited. Record this inherited-source diagnostic rather than claiming the checker passed after merge. Canonical project documents remain untouched.

+## Empty Composer Hint Follow-up
+
+- User approved the first proposed interaction: show a lightweight “给我一点提示” action only when the consultation input is empty, hide it when typing and remove the fixed “我也说不清，你带我看看” link below replies. Update the existing trial without desktop focus changes.
+- Same-task ownership resumed and verified; rechecked task/entry and peer scopes. The protocol-boundary peer is complete but unmerged and not live in this trial; preserve its separate prompt-policy decisions for its designated integration task, do not change backend policy as part of this UI request. Existing manual refresh is already included.
+- Plan: modify only the composer entry and fixed follow-up link, preserve true generated cards/free input/retries, add focused UI and browser checks, build and update trial Renderer while retaining Main and persisted data where possible. No cloud publication or deliberate model test request.
+
+### Hint Implementation And Verification
+
+- Replaced the filled “帮我看看” pill with a transparent “给我一点提示” text action in the empty composer. Typing hides it; clearing or whitespace restores it. A fixed minimum action-row height and left flex slot retain the send button’s position. Removed only the client-added “我也说不清，你带我看看” footer; identical text genuinely returned by the Agent still renders and sends as an ordinary generated reply.
+- Preserved quick replies, free input, references/drafts, failure/cancel/interruption retries, and one-click request behavior. When an old unconfirmed suggestions payload still says “帮我看看”, retry now reuses the complete original payload and request ID; ordinary questions and already-confirmed requests cannot reuse it. Old guided-help intent remains readable for history compatibility; no backend/cloud policy changed.
+- Verification passed: 59 UI unit tests (including five legacy pending-payload cases), 14 headless Chrome layout tests at 319/508px, typecheck, full lint followed by final changed-file lint, and production Renderer/Main/Preload/utility compile. Legacy regressions failed before the compatibility fix and passed afterward. Updated shared Electron E2E assertions but did not launch a native test application. No real model request was made for verification.
+- Built with `corepack pnpm run build:vite --emptyOutDir false` so the live Renderer can keep loading its old hashed assets until the deliberate refresh. Saved previous index and bootstrap/launch descriptors locally outside Git; current Main is retained for the pending Renderer update.
