+# Task: Remove redundant AI Design progress banner
+
+## Identity
+
+- Task ID: 20260904-remove-design-progress-4e8a1c73
+- Mode: Feature
+- Branch: codex/20260904-remove-design-progress-4e8a1c73-remove-design-progress
+- Worktree: D:\Datas\OthersProjects\.codex-worktrees\makelore\20260904-remove-design-progress-4e8a1c73
+- Base commit: 403236115bf81e7617856cd8219b1be23f6abbb8
+- Owner: codex-root
+- Status: Ready for Integration
+
+## Scope
+
+- Remove the visible AI Design assistant-progress banner from the main conversation
+  pane. The right-side “AI 听懂的想法” projection remains the sole surface for the
+  currently organized design understanding.
+- Preserve immediate provisional user messages, their `发送中` / `正在确认` feedback,
+  canonical assistant replies, and the existing internal stream reconciliation.
+- Update focused Renderer regression coverage only. Do not change the Works Square
+  server, Electron Main/API contracts, Current Specification authority, generation,
+  navigation, packaging, publication, or unrelated project records.
+
+## Intent And Constraints
+
+- The user explicitly identified the progress banner as duplicated information and
+  requested that it be removed. It must not be replaced by another central loading
+  surface.
+- Raw assistant deltas remain non-canonical and must stay out of the conversation.
+  Removing their presentation must not remove their Store state or change operation
+  identity and failure recovery.
+- Keep the pending user bubble as the honest acknowledgement that a send was accepted
+  locally; only the redundant assistant-side banner is removed.
+- Concurrent Task Gate and Planning Gate passed in the managed isolated worktree from
+  exact client `main` base `403236115bf81e7617856cd8219b1be23f6abbb8`.
+- The root integration task overlaps the same AI Design area but owns only root/canonical
+  reconciliation; this feature task owns the component and focused test in isolation.
+- ADR-007 remains unchanged: the server Current Specification is semantic authority,
+  while the right-side youth summary is its secondary client projection.
+
+## Outcome
+
+- `DesignConversationPane` no longer subscribes to `assistantStreams` for visible
+  presentation and no longer renders the “AI 正在整理你的想法” / result-confirmation
+  banner in the conversation timeline.
+- Raw assistant deltas remain Store-owned transport state and still never appear as
+  committed chat content. The final canonical assistant turn remains unchanged.
+- Provisional user messages and their `发送中` / `正在确认` labels remain visible, so
+  removing the duplicated assistant banner does not remove send acknowledgement.
+- The right-side “AI 听懂的想法” card and all Current Specification behavior are
+  unchanged.
+
+## Verification
+
+- Focused Renderer test: `pnpm exec vitest run tests/unit/image-canvas-page.test.tsx`
+  passed `1 file / 10 tests`.
+- TypeScript: `pnpm exec tsc --noEmit` passed.
+- Scoped ESLint for the changed component and test passed.
+- The isolated worktree dependencies were restored from the existing lockfile with
+  offline, frozen resolution and lifecycle scripts disabled; no dependency version or
+  lockfile changed.
+
+## Follow-ups
+
+- Integrate this source commit after the existing root AI Design integration task has
+  safely completed or released its ownership. Do not overwrite that task's dirty
+  canonical-document reconciliation or its three preserved foreign records.
+
+## Promotion Candidates
+
+- Target: `.project-docs/30-worklog/current-state.md`, AI Design presentation wording
+  in `.project-docs/20-architecture/system-overview.md`, and the corresponding rule in
+  `.project-docs/40-domain/business-rules.md`.
+- Proposal: record that raw assistant deltas stay internal and invisible in the main
+  conversation; the right-side Current Specification projection is the single surface
+  for the AI's organized understanding. The main timeline shows provisional/canonical
+  user messages and canonical assistant turns, without a separate assistant-progress
+  banner.
+- Evidence: the user explicitly identified the banner as duplicated information and
+  requested its removal; focused Renderer coverage confirms the banner is absent while
+  send acknowledgement remains.
+- Future impact: later conversation changes should not reintroduce a second summary or
+  progress card into the timeline merely because assistant delta transport state exists.
+- Semantic conflict: this narrows the prior task's optional visible progress projection;
+  it does not change ADR-007 or server authority. Human confirmation is already present
+  in this task request.
