+# Task: Integrate youth-facing AI Design client changes
+
+## Identity
+
+- Task ID: 20260902-design-youth-client-integration-7a6d3c92
+- Mode: Integration
+- Branch: codex/20260902-design-youth-client-integration-7a6d3c92-design-youth-client-integration
+- Worktree: D:\Datas\OthersProjects\makelore-design-youth-integration-7a6d3c92
+- Base commit: 7552cf59526449c29d663a769c0fb62d84a1a759
+- Owner: codex-root
+- Status: In Progress
+
+## Scope
+
+- Integrate reviewed Design Youth source commit
+  `0fd32a2d49045a8f9e7f2e19ba6477f48f93e30c` onto the current client frontier
+  `7552cf59526449c29d663a769c0fb62d84a1a759`.
+- Replace the default professional field matrix with conversation plus one compact
+  “我的创作” card for creators aged 8-16, while retaining contextual “精细调整”.
+- Preserve the V2 Current Specification reducer, immutable Quote confirmation,
+  Task/Asset reconciliation, stable operation identities, and Main-owned transport.
+- Own the integration record, canonical current-state reconciliation, cross-frontier
+  verification, and safe promotion to local `main`.
+- Correct the current frontier's eager CommonJS load of the ESM-only Pi package
+  manager, which the integrated Electron E2E exposed before any Design page opened.
+
+## Intent And Constraints
+
+- One understandable default serves creators aged 8-16; there is no separate age or
+  expert mode. Advanced controls remain progressive disclosure over canonical state.
+- Direct choices use existing typed commands. Renderer drafts, assistant deltas,
+  Quote/Task events, and localized copy never become Specification authority.
+- Known compiler/Task issues render code-based youth-facing Chinese copy; unknown
+  messages use a fixed safe fallback rather than raw server or Provider text.
+- Do not add or change a database migration, DTO/API, semantic store, compatibility
+  layer, Provider route, pricing path, deployment, publication, push, or paid request.
+- Keep the Pi package-manager correction limited to loading its existing dependency
+  on demand for remote Device Package installation; do not change package semantics.
+- Preserve the two user-owned untracked records in the root checkout exactly as-is:
+  `20260901-package-122-c5e8.md` and `20260901-package-123-d7f3.md`.
+- The source task record is read-only evidence. The integrated default branch will
+  retain this integration task and canonical memory, not import a second active task
+  ownership record.
+
+## Concurrent Task Gate
+
+- Task ID: `20260902-design-youth-client-integration-7a6d3c92`
+- Mode: Integration
+- Branch: `codex/20260902-design-youth-client-integration-7a6d3c92-design-youth-client-integration`
+- Worktree: `D:\Datas\OthersProjects\makelore-design-youth-integration-7a6d3c92`
+- Base commit: `7552cf59526449c29d663a769c0fb62d84a1a759`
+- Ownership result: Claimed in an independent linked worktree. The preceding Model
+  Tools integration lock is complete and released; its exact client frontier is this
+  task's base commit.
+- Other local state: root `main` contains only the two allowlisted user-owned untracked
+  task records. They are outside the source commit's changed paths and remain untouched.
+- Gate result: Passed.
+
+## Project Context Loaded
+
+Read:
+- the startup memory set, memory index, project positioning, success criteria,
+  decision index, current state, system overview, business rules, and ADR-007;
+- source task `20260902-design-youth-client-7c5e3a82`, its exact commit boundary,
+  verification evidence, follow-ups, and promotion candidates;
+- current Model Tools integration record and its released frontier.
+
+Relevant understanding:
+- The Current Specification remains the only semantic authority. The Creation Card
+  and Fine Tune drawer are projections/editors over the existing V2 reducer.
+- Main remains the only Works Square transport and secret owner. Generation confirms
+  only an immutable Quote ID; public copy must not expose Provider internals.
+- Youth readiness language may offer to check a production plan, but must not claim
+  server readiness before concrete Quote blockers have been evaluated.
+- Source verification already covers responsive composition, direct edit, chat,
+  Quote/Task flow, stable Shot identities up to 24, terminal Quote-blocked settlement,
+  safe issue copy, typecheck, lint, build, broad tests, and Electron E2E.
+- The new frontier changes Coding model tools/device packages and canonical memory,
+  not the ImageCanvas product/test files. Canonical documentation must be reconciled
+  in this integration task rather than overwritten from the older source base.
+- Planning Gate result: Passed.
+
+## Outcome
+
+- Integrated reviewed source `0fd32a2d49045a8f9e7f2e19ba6477f48f93e30c`
+  onto the exact released Model Tools frontier with merge
+  `16157388afc2f6103aaee0bfd3c4e4e80c8fec48` and no source conflict.
+- Canvas now presents one conversation-first “我的创作” card, A/B/C youth choices,
+  “你帮我选”, responsive single mounting, and contextual “精细调整” while the
+  server-owned Current Specification remains the only semantic authority.
+- Quote blockers are revision-bound and terminal blocked responses/events settle
+  pending operations. Compiler and Task issues use code-based youth-facing Chinese
+  copy with fixed unknown fallbacks instead of raw technical messages.
+- Fine Tune preserves stable Shot ids, timing/camera/framing/motion/focus/transition
+  metadata, supports the full 24-Shot server contract, and treats a cleared beat as
+  explicit deletion rather than submitting an invalid null value.
+- The integrated Electron check exposed a pre-existing current-frontier startup
+  blocker before the Design page opened: Vite externalized an ESM-only static Pi
+  package-manager import as top-level CommonJS `require`. Commit
+  `c5447ae90c434c06dbafa724b229d8459cb829d0` now dynamically imports that existing
+  module only for remote Device Package installation; package semantics are unchanged.
+- Removed the imported source task record from default-branch ownership scope; this
+  integration record and canonical current state contain the promoted evidence.
+- No database migration, public DTO/API, second semantic store, compatibility layer,
+  Provider activation, paid generation, package, deployment, publication, push, or
+  PR was added or performed.
+
+## Verification
+
+- `corepack pnpm exec vitest run tests/unit/youth-form-projection.test.ts tests/unit/youth-creation-card.test.tsx tests/unit/youth-issue-copy.test.ts tests/unit/fine-tune-drawer.test.tsx tests/unit/image-workspace-store.test.ts tests/unit/image-canvas-page.test.tsx` — 6 files / 40 tests passed on the integrated frontier.
+- `corepack pnpm exec vitest run tests/unit/device-package-manager.test.ts` — 5 tests
+  passed after the ESM loading correction.
+- `corepack pnpm run typecheck` — passed before and after the correction.
+- Scoped ESLint over all Design Youth source/tests and the corrected Device Package
+  manager — passed.
+- `corepack pnpm run build:vite` — passed; only existing chunk-size and mixed
+  static/dynamic import warnings were reported. The active Main chunk contains the
+  expected dynamic Pi import and no eager Pi package-manager `require`.
+- The first Electron run deterministically failed 2/2 at app launch with
+  `ERR_PACKAGE_PATH_NOT_EXPORTED`, before either test reached Canvas. After
+  `c5447ae`, the identical
+  `corepack pnpm exec playwright test tests/e2e/image-workspace-v2.spec.ts` run passed
+  2/2 in 3.8 seconds, covering Prompt Museum isolation plus desktop/375 px/768 px
+  Design conversation, direct edit, Quote confirmation, and Task flow.
+
+## Follow-ups
+
+- Run moderated usability sessions with creators aged 8-16 after packaging.
+- Production package/deployment and real-account Design V2 smoke remain separate
+  release gates; paid Provider activation still requires explicit authorization.
+
+## Promotion Candidates
+
+- None recorded.
