# Task: Load AI Design video duration options from server

## Identity

- Task ID: 20260818-video-duration-server-config-7b4e
- Mode: Feature
- Branch: main
- Worktree: D:\Datas\OthersProjects\makelore
- Base commit: 86ffeac066ca03cdaacb6f12eec11dc1e258432a
- Owner: codex
- Status: Ready for Integration

## Scope

- Update the AI Design video confirmation card to use the active Quote's
  server-provided `generationOptions.durations` for both rendering and
  validation, removing the client-side 2–6 second range coupling.
- Add a regression proving an enabled duration outside the former local range
  is rendered, can be selected, re-quoted, and submitted through the existing
  confirmation flow.
- Do not change the API payload or provider contract; the server Quote remains
  the authority for available and disabled durations.

## Intent And Constraints

- Preserve disabled options and the existing “must re-quote after changing a
  parameter” behavior.
- Keep legacy/invalid quotes fail-closed when no enabled server duration is
  selected; use a server-driven validation message rather than naming a local
  range.
- Keep the local preview adapter unchanged; this change targets the cloud
  Makelore adapter and the shared Quote confirmation UI.

## Outcome

- `ImageCanvas` now renders enabled video durations directly from the active
  server Quote's `generationOptions.durations`.
- Confirmation validation now accepts only a non-null duration that matches an
  enabled server option; the previous client-side 2–6 second range check was
  removed so future server configuration changes do not require a client
  release.
- The confirmation error is server-driven and no longer names a local range.
- Added a regression using server-provided `7` and `15` second options that
  verifies the options are shown, the initial invalid selection is blocked,
  `15` survives re-quoting, and the final confirmation receives `15`.

## Verification

- Red test: the new regression initially received only `['', '2', '6']`,
  proving the old client-side range filter was still active.
- `pnpm exec vitest run tests/unit/image-canvas-page.test.tsx tests/unit/works-square-design-workspace.test.ts` — 79 passed.
- `pnpm run typecheck` — passed.
- `pnpm exec eslint src/pages/ImageCanvas/index.tsx tests/unit/image-canvas-page.test.tsx` — passed.
- `pnpm run build:vite` — passed for Renderer, Electron Main, and Preload;
  only existing dynamic-import and chunk-size warnings were reported.
- `git diff --check` — passed; Git reported only the repository's LF-to-CRLF
  checkout warnings.

## Follow-ups

- The server must continue publishing a valid enabled duration list in each
  video Quote; an empty or all-disabled list intentionally keeps confirmation
  unavailable.

## Promotion Candidates

- None recorded.
