+# Task: Handle AI Design chat generation handoff
+
+## Identity
+
+- Task ID: 20260907-design-chat-generation-handoff-client-7d3a9c41
+- Mode: Feature
+- Branch: codex/20260907-design-chat-generation-handoff-client-7d3a9c41-design-chat-generation-handoff
+- Worktree: D:\Datas\OthersProjects\.codex-worktrees\makelore\20260907-design-chat-generation-handoff-client-7d3a9c41
+- Base commit: bce20d9e4dad99565714bd2c0ca1ef4806426f57
+- Owner: codex-root
+- Status: Ready for Integration
+
+## Scope
+
+- Verify that the existing client event contract can consume a server-owned
+  `开始生成` handoff without introducing a second Renderer command or public DTO.
+- Preserve the original optimistic user message, activity/reply settlement, stable
+  operation identity, and the offered Quote created immediately after the committed
+  chat event.
+- Add focused Store coverage for two consecutive Direction projections belonging to
+  the same accepted chat command.
+
+## Intent And Constraints
+
+- Electron Main remains the only network authority. Source inspection showed that no
+  new Renderer orchestration is needed: the server can emit the committed chat and
+  subsequent Quote as two existing `design.direction.updated` events in one Run.
+- Never infer generation intent from assistant prose or duplicate phrase matching in
+  the client. The server owns interpretation and the Quote transaction.
+- Keep Quote and generation confirmation separate: automatic handoff may create an
+  immutable Quote, but only explicit user confirmation may create a Task or reserve
+  Token Points.
+- Derive a stable follow-up operation identity from the committed chat Interaction,
+  and do not replay an already accepted/unknown mutation under a new identity.
+
+## Project Context Loaded
+
+- Task context: feature task `20260907-design-chat-generation-handoff-client-7d3a9c41`
+  owns this managed linked worktree at base `bce20d9e…`.
+- Read: agent-entry and planning-gate docs, memory index, project positioning,
+  integrated current state, decision index/system overview, ADR-007, architecture
+  module/data-flow maps, domain/success criteria, evidence/reflection/commitment/stale
+  indexes, and the recent Design activity and repeated-turn peer task records.
+- Project goal: a youth-friendly Canvas whose Current Specification, immutable Quote,
+  and confirmed Task remain server-authoritative.
+- Current integrated focus: optimistic chat, operation-scoped activity and committed
+  assistant streaming are already present; repeated identical user text is valid.
+- Decisions affecting this task: ADR-007 requires stable operation identity, Main-owned
+  transport, immutable Quote display, and explicit Quote-ID confirmation.
+- Evidence and commitments: production logs show an input Run completed without any
+  Quote/Task command; the real paid confirmation smoke remains separately pending.
+- Likely modules: `shared/image-workspace.ts`, the Works Square adapter, Renderer
+  image-workspace Store, and their focused tests.
+- Unknowns/conflicts: source inspection must identify the narrowest post-commit event
+  seam and ensure reconnect/replay cannot create duplicate Quote requests. The root
+  worktree's unrelated untracked records are outside this isolated task. No active
+  peer has a conflicting Design scope.
+- Gate result: Passed.
+
+## Outcome
+
+- Confirmed that Main maps every Gateway `design.direction.updated` event
+  independently and the Store applies canonical form projections even after the
+  original optimistic operation has settled.
+- Added a Store regression for the real sequence: committed `chat` projection,
+  immediately followed by `quote_request` with the same client operation identity.
+  The test proves the draft/pending chat settles once, the completed activity remains
+  bound to its Turn, and the offered Quote remains visible.
+- No client product code, shared contract, routing, or UI change was necessary.
+
+## Verification
+
+- `pnpm exec vitest run tests/unit/image-workspace-store.test.ts --maxWorkers=1`
+  passed (33 tests).
+- `pnpm exec eslint tests/unit/image-workspace-store.test.ts` passed.
+- `pnpm run typecheck` passed.
+- `git diff --check` passed.
+
+## Follow-ups
+
+- Integrate and deploy with server task
+  `20260907-design-chat-generation-intent-4f8c2a91`, then perform the recorded real
+  Quote/confirmation smoke.
+
+## Promotion Candidates
+
+- Target: `.project-docs/20-architecture/data-flow.md` and integrated current state.
+  Proposal: record that one accepted Design chat Run may carry a committed chat
+  Direction projection followed by an immutable Quote projection under the same
+  client command identity; the Store converges both without issuing a second
+  mutation. Evidence is the 33-test Store suite and the cross-repository server task.
+  This is compatible with ADR-007 and needs no separate product-direction decision.
