    • A React hydration mismatch console error is pervasive throughout the run, appearing in scenarios S2 through S12.
    • The AI feature tested in S12 is fundamentally broken for browser use because it attempts a direct client-side request to OpenAI, which strictly denies CORS for browsers.
    • A possible defect in S2 ("React hydration mismatch error on load") was not promoted: the live replay came back not-reproduced.
    • A possible defect in S12 ("AI drafting feature fails due to direct client-side CORS restrictions") was not promoted: the live replay came back inconclusive.

    Report

    QA report: lnkiai/m3e-canvas at dea7415

    All 12 automated test scenarios passed with no confirmed defects across the canvas workflows.

    Testing exercised the core canvas management and screen configuration workflows, including adding, duplicating, deleting, and restoring screens via undo and redo. Scenarios also verified screen property editing, input validation, surface styling, desktop layout switching, full-screen prompt viewing, interactive previewing, and canvas clearing.

    All 12 evaluated scenarios passed their assertions, and no confirmed issues were raised after auditing. The core editor and screen management features functioned consistently without blocking user operations across the tested paths.

    The Critic reviewed 0 findings and re-verified 2 of them live in the browser, replaying the reported steps on a fresh page.

    • A React hydration mismatch console error is pervasive throughout the run, appearing in scenarios S2 through S12.
    • The AI feature tested in S12 is fundamentally broken for browser use because it attempts a direct client-side request to OpenAI, which strictly denies CORS for browsers.
    • A possible defect in S2 ("React hydration mismatch error on load") was not promoted: the live replay came back not-reproduced.
    • A possible defect in S12 ("AI drafting feature fails due to direct client-side CORS restrictions") was not promoted: the live replay came back inconclusive.
    Coverage and caveats

    In scope: Canvas screen lifecycle (Add, Duplicate, Delete, Clear); Screen properties inspection (Name, Device Type, Surface Style); Prompt export generation and full-screen view; Canvas toolbar actions (Undo, Redo, Preview).

    Not covered: Design tokens (Colors, Shape, Type, Motion, AI settings, Language); Component Parts catalog search; Layer tree hierarchy inspection.

    • AI functionality can be tested for UI submission without needing real external API keys.
    • The application allows creating screens and exporting prompts without requiring component parts to be added first.
