    Add structured preview exception hierarchy

    LeoVasanko released this 2026-08-13 03:45:42 +00:00 | 10 commits to main since this release

    PreviewError subclasses carry a concise short label for UI, a full log
    message, backend name, and metadata fields (OnlyOffice code/status/url,
    backend stage, timeout seconds, cancel reason). Exceptions travel across
    the worker pool wire pickled in the binary response payload (ok=False)
    and are re-raised with their original type on the caller side. Combined
    pipelines such as pdf+pyvips tag the failing stage.
