/**
 * Shape of FileResource.meta after the file service's preview
 * pipeline runs. Two categories:
 *
 * - Caller-stamped (set by upload-time clients, stable):
 *     questionId, fileKey - written by `file:process` when the
 *     assessment workflow invokes it; lets the recruiter UI map
 *     a FileResource back to the answer's question without
 *     consulting attempt.attributes.answers[].
 *
 * - Render-time (regenerated on every showFile call, transient):
 *     previewUrls.{pages,mediaUrl,streamingUrl,originalUrl,thumbnailUrl} -
 *     presigned S3 URLs for the bytes the FE renders. Expire
 *     after `previewUrlsExpiresAt` (~15 min). `streamingUrl` is
 *     the ffmpeg re-muxed (faststart mp4 / genpts webm) variant
 *     for browser playback; populated only when the re-mux pass
 *     has completed.
 *
 * - Provenance markers (set by writers, never expire):
 *     durationSource ('client' | 'remux') - 'client' when the
 *     FE-supplied wall-clock durationMs is the only reliable
 *     source (browser-recorded webm pre-remux); 'remux' once
 *     the ffmpeg re-mux pass has overwritten attributes.durationSeconds
 *     with a probed value. FE branches on this for the streaming
 *     URL fallback (and also drives whether `streamingUrl` is set).
 *
 * - Heavy content reference:
 *     resultRef - presigned URL to the file service's extraction
 *     JSON (full transcript, raw OCR, per-page text, structured
 *     AI fields). FE fetches this only on demand.
 *
 * All keys optional; presence depends on file kind and
 * conversion progress.
 * @export
 * @interface FilePreviewMetaSchema
