 ## Integrated Through
 
+- AI Design streamed-reply diagnosis
+  `229b1b1ce39b7f1541a93ea3c980ab82b6d6266c` and client fix
+  `23f96a523eb37d8397bb3766ce95a59d56e59225` from tasks
+  `20260904-diagnose-design-stream-6a4e9c21` and
+  `20260904-fix-design-stream-4f7b91c2` are integrated onto local `main` and
+  canonically reconciled by task `20260904-integrate-design-stream-5e7c2a91`.
+  The existing post-validation `design.assistant.delta` transport is visible again as
+  exactly one provisional assistant-shaped bubble tied to its pending chat identity;
+  canonical `workspace.turns` still owns history and replaces the unfinished bubble,
+  while unknown outcomes keep the same identity and partial reply. The removed generic
+  “AI 正在整理你的想法” banner is not restored. A ready conversation now offers an
+  inline Quote step; successful Quote requests reveal the confirmation on desktop or
+  open it on mobile, but only explicit immutable Quote-ID confirmation creates a paid
+  Task. Unknown Quote requests disable both entry points and retry the original
+  operation. Focused tests passed 35/35, the Electron Quote-confirm-Task flow passed
+  1/1, typecheck, scoped lint, Vite build, document gates, and independent review
+  passed. The ordinary full suite had one unrelated Pi real-process 2-second timing
+  miss among 1,873 passing tests and 2 skips; that exact test passed immediately in
+  isolation, and the pressure test passed 1/1. Provider-native first-token streaming
+  remains a separate server follow-up; no server, database, billing, Plugin,
+  packaging, deployment, publication, or remote push changed.
