# 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.
