Base commit: 0eed70fa63
Owner: codex
Status: Ready for Integration

Reproduce the visible six-second video duration alongside missing-duration/missing-shots errors through YouthCreationCard and its real store. Own only that form/quote preparation path, focused tests and this record; no navigation, billing or provider changes.

Concurrent and Planning Gates Passed: official check/start/status verified the exact isolated feature identity and base above. Read entry, own task, positioning/current integrated snapshot, Design ADR, relevant architecture/domain/evidence/reflection/commitments. Peer task records inspected read-only; historical Design tasks share code paths but retain the same server-owned Specification and prepare-before-quote contract. Placeholder peer scopes remain unknown; no concrete dependency or semantic conflict affects this isolated work. Preserve unrelated dirty root documents and completed draft-diagnosis task. No subagents or live model calls.

Reproduced the screenshot's contradictory duration display: a canonical null duration rendered as six seconds while video_duration_required remained. Independently reproduced an unsuccessful parameter save retaining the unaccepted optimistic duration.
Missing duration now renders an explicit selector populated solely from server-supported durations; quotation remains disabled until selection is saved. Existing accepted durations retain the stepper, including normal video-mode conversion's existing explicit duration write.
Parameter controls reconcile to accepted Workspace values after completion or failure, without applying a response to another selected Workspace.
video_shots_required remains visible as actionable AI-preparation guidance, not a red instruction for a child to write internal shots. Other compilation blockers remain unchanged; the server's compile/confirm authority is not relaxed.
Product ownership: src/pages/ImageCanvas/YouthCreationCard.tsx and youth-issue-copy.ts. Regression ownership: tests/unit/youth-creation-card.test.tsx, tests/e2e/image-workspace-v2.spec.ts and scripts/diagnostics/design-video-flow.test.tsx.

Red evidence: real React component test rendered six seconds for null; a second test rendered the misleading shot error with a valid saved duration; a failed-save test retained seven instead of saved six. Each was run before its correction.
pnpm 10.33.4: 71 tests passed across youth-creation-card, image-workspace-store and image-canvas-page. Existing store regression confirms blockers clear only on a new canonical Specification revision; preparation failure still stops quotation.
Offline cross-repository flow: 3 passed using real React controls, Zustand commands, server reducer/preparation orchestration/capability compiler, fixture model output and in-memory asset. New incomplete-video case starts with a selected first frame, null duration and no shots, sees the placeholder, saves six seconds, clears the old duration error, prepares one shot, and reaches explicit confirmation. Also reran original image-to-video path and playback projection.
Server companion 20260927-design-video-validation-a9e4317b: 10 preparation tests passed.
pnpm run typecheck, scoped ESLint, pnpm run build:vite passed. Build reports existing Browserslist age, chunk-size and mixed dynamic/static import warnings.
Electron image-workspace-v2 spec: 2 passed, including new duration selection/reload persistence assertions in the existing production-plan flow. Host API/model/provider transport remain fixtures; no paid generation or production database access.

Main is unchanged. This fix needs a client merge and rebuilt client rollout; it requires no server product patch, database migration or environment variable. The separate server Reasoner fix 7799a746699571d71ac0b009d6faa5fd989b501a remains independently ready, not included here.
The screenshot alone cannot prove the deployed Workspace's exact stored duration or that a save failed; the supported code paths and matching contradiction were reproduced locally. Real-account installed-client generation is not claimed.

Target: ADR-007/README video UI clarification during integration. Proposal: an absent duration must never look accepted, rejected edits must reconcile to accepted state, and AI-owned motion preparation must not be phrased as user-required internal shots. Evidence: red/green component tests, paired offline compiler flow and Electron persistence test. Future impact: preserve the existing single Specification authority and prepare-before-quote contract; no semantic conflict or new product-direction decision.
