+  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,

+# Task: Integrate AI Design streamed replies and quote handoff
+
+## Identity
+
+- Task ID: 20260904-integrate-design-stream-5e7c2a91
+- Mode: Integration
+- Branch: codex/20260904-diagnose-design-stream-6a4e9c21-diagnose-design-stream
+- Worktree: D:\Datas\OthersProjects\.codex-worktrees\makelore\20260904-diagnose-design-stream-6a4e9c21
+- Base commit: 23f96a523eb37d8397bb3766ce95a59d56e59225
+- Owner: codex-root
+- Status: Ready for Integration
+
+## Scope
+
+- Integrate diagnosis commit `229b1b1ce39b7f1541a93ea3c980ab82b6d6266c`
+  and implementation commit `23f96a523eb37d8397bb3766ce95a59d56e59225`
+  from tasks `20260904-diagnose-design-stream-6a4e9c21` and
+  `20260904-fix-design-stream-4f7b91c2` onto local client `main`.
+- Reconcile the accepted promotion candidate into `current-state.md`, the AI Design
+  architecture boundary, and business rules: a delta may appear only as one visibly
+  unfinished assistant reply; Quote review remains separate from paid generation
+  confirmation.
+- Preserve the three known foreign untracked task records in the root checkout exactly
+  as found. Do not modify the Works Square server, billing, Plugin navigation,
+  packaging, publication, remote refs, or any unrelated client feature.
+
+## Intent And Constraints
+
+- The user explicitly requested this completed client fix be merged to the main branch
+  and had already confirmed the product decision behind the canonical wording change.
+- Root `main` was verified at exact head
+  `aa3f52a8f8414c9ad939d396bd2828c3e07c70e7`, with only the three previously known
+  untracked records. The source is a linear descendant of that frontier, so use a
+  fast-forward after canonical reconciliation; do not stash, reset, clean, add, or
+  adopt the foreign records.
+- Keep `workspace.turns` as canonical conversation history. The provisional stream is
+  presentation tied to an existing pending chat identity, never a second completed
+  turn or generic progress banner.
+- Keep production authorization two-step: Quote request/reveal may be prompted by the
+  conversation, while only explicit confirmation of the immutable Quote ID creates a
+  paid Task.
+
+## Project Context Loaded
+
+- Concurrent Task Gate passed for integration task
+  `20260904-integrate-design-stream-5e7c2a91`, owner `codex-root`, mode Integration,
+  branch `codex/20260904-diagnose-design-stream-6a4e9c21-diagnose-design-stream`,
+  worktree
+  `D:\Datas\OthersProjects\.codex-worktrees\makelore\20260904-diagnose-design-stream-6a4e9c21`,
+  base `23f96a523eb37d8397bb3766ce95a59d56e59225`; the repository Integration lock is held.
+- Loaded the startup memory set, current integrated state, system overview, business
+  rules, ADR-007 context, and both completed source task records including outcome,
+  verification, follow-up, and promotion candidates.
+- Relevant active peers are unrelated historical/stale task records. The exclusive
+  Integration lock prevents concurrent canonical reconciliation; no peer owns a
+  conflicting current AI Design product decision.
+- The old canonical rule hid raw delta text entirely. The accepted source narrows that
+  rule without weakening authority: exactly one provisional bubble may paint the
+  already validated assistant text, while canonical turns, Current Specification,
+  stable operation identity, Quote identity, and explicit payment confirmation remain
+  unchanged. The user's confirmation resolves the semantic conflict.
+- Planning Gate result: Passed.
+
+## Plan
+
+1. Reconcile the accepted AI Design stream/Quote behavior into canonical architecture,
+   business rules, and current-state integration evidence.
+2. Re-run task-aware document and source verification at the final integration head.
+3. Commit the integration record, fast-forward exact root `main`, verify the three
+   foreign untracked files are unchanged, then complete and release the Integration
+   lock.
+
+## Outcome
+
+- Accepted and reconciled both source tasks on top of exact local `main` frontier
+  `aa3f52a8f8414c9ad939d396bd2828c3e07c70e7`; their commit chain is linear and
+  contains no unrelated product changes.
+- Updated the canonical architecture and business rules to distinguish one
+  operation-bound unfinished assistant bubble from canonical conversation history
+  and from the prohibited generic progress banner. Unknown operations retain their
+  identity/partial text and cannot be erased by unrelated updates.
+- Recorded the ready-conversation Quote handoff: desktop reveals the offered Quote,
+  mobile opens it, and neither path creates a Task until the user explicitly confirms
+  the immutable Quote ID. Unknown Quote requests keep and retry the original operation
+  instead of creating another intent.
+- Updated `current-state.md` with source commits, behavior, verification, the known
+  post-validation streaming limitation, and the explicit no-server/no-billing scope.
+- Prepared the integrated branch for a fast-forward of root `main`; the root's three
+  pre-existing untracked task records remain outside this commit and are not adopted,
+  staged, modified, moved, or deleted.
+
+## Verification
+
+- Source task evidence: focused 35/35, Electron Quote-confirm-Task 1/1, typecheck,
+  scoped ESLint, Vite build, diff check, pressure 1/1, and independent final review
+  passed. The full suite's only miss was an unrelated Pi process 2-second timing check,
+  which passed immediately in isolation.
+- Integration-head rerun: focused Renderer/store/Card suite 3 files / 35 tests passed;
+  `pnpm exec tsc --noEmit` passed.
+- Integration-head Electron flow passed 1/1 and again exercised the conversation CTA,
+  Quote visibility, explicit 12-Design-Point confirmation, and queued Task projection.
+- `git diff --check`, `check_project_docs.py`, and task-aware
+  `check_doc_drift.py --task-id 20260904-integrate-design-stream-5e7c2a91` passed.
+
+## Follow-ups
+
+- Provider-native first-token streaming still requires a separately scoped server
+  contract; this integration only exposes the existing validated-message chunk
+  projection honestly.
+
+## Promotion Candidates
+
+- None. The source candidates were accepted by the user and applied to canonical
+  architecture, domain rules, and current state in this integration task.
