Base commit: da29294979
Owner: codex-root
Status: Ready for Integration

Integrate client source commit 81b524a02c2cf51304090afa8fb89d27c72c5d2b from exact base da29294979da4ce041edf992b590ee6ea170a44f.
Promote the operation-scoped AI Design activity projection into canonical client memory.
Verify Main event normalization, Renderer reconciliation, conversation rendering, and existing Design streaming behavior.

Render only the server's fixed public lifecycle stages beneath the matching optimistic user message.
Keep design.assistant.delta as the single provisional assistant-text stream and the right-side Living Form as the Current Specification projection.
Never render raw chain-of-thought, prompt/provider/tool payloads, or a duplicate global “整理进度” banner.
Preserve stable operation identity and existing unknown-result reconciliation.
Do not touch or adopt unrelated changes in the root worktree.

Fast-forwarded the exact source commit from the recorded base without conflict.
Integrated Main-normalized public Design activity, operation-scoped Renderer reconciliation, terminal-event convergence, and the conversation-attached activity panel while preserving optimistic user messages and canonical assistant replacement.
Fixed two integration-review findings: a later chat no longer erases earlier completed/unknown activity, and each pending operation now renders its user message, activity, and provisional assistant stream as one ordered group.
Promoted the accepted transient-activity boundary into ADR-007, architecture maps, data flow, domain rules, and current integrated state.
No server contract, database, billing, Quote/Task, navigation, package, deployment, publication, or Provider behavior changed.

pnpm exec vitest run tests/unit/image-workspace-store.test.ts tests/unit/image-canvas-page.test.tsx tests/unit/works-square-design-workspace.test.ts tests/unit/image-workspace-route.test.ts — 69 passed.
pnpm exec tsc --noEmit — passed.
Focused ESLint across all eight changed TypeScript/TSX files — passed.
pnpm run build:vite — passed; only existing chunk-size, dynamic-import, and stale Browserslist-data warnings were emitted.
git diff --check — passed.
Independent integration review — PASS after the two multi-operation findings were fixed and covered.

Add an explicit snapshot/cursor reseed contract for a Gateway cursor expired response in a separate transport-resilience task.

Applied: ADR-007, system overview, module map, data flow, domain rules, and current integrated state now define operation-scoped public activity as transient presentation rather than Design authority or model reasoning.
