… cannot be created DropboxAdapter::getUrl() returned the placeholder '#' when Dropbox could not create a shared link (typically because the file never reached Dropbox after a failed pending upload). The admin serializer exposed that '#' as private_url, and FNreview (mu.private_url || mu.public_url) treated it as a real URL: clicking the material opened '#' in a new tab instead of falling back to the public storage link. - DropboxAdapter::getUrl() returns '' instead of '#' (the parent signature forbids null). - AbstractFileDownloadStrategy::getUrl() normalizes an empty result to null and drops the '#' special-casing; misses are still not cached. Consumers already treat null as "no link": FNreview falls back to public_url, summit-admin validates with isValidUrl(), CFP prefers public_url. Refs ClickUp 86bbxj6de
…he Error transition processPendingMediaUploads() re-attempted a failed PendingMediaUpload on the very next cron tick (every minute) and gave up after 3 attempts, so a transient Dropbox failure (5xx, timeout, rate limit) became a permanent Error row within ~3 minutes. The transition was logged at warning level, which production drops at LOG_LEVEL=error, so nobody noticed until the material link broke in FNreview. - Wait 5 * 2^(attempts-1) minutes (5, 10, 20, 40) since LastEdited before retrying a row that already failed; rows with no attempts run immediately. - Default max_retries raised from 3 to 5. - Log the Error transition (retry guard and final failed attempt) at error level; non-final failures stay at warning. No schema change: Attempts and LastEdited already carry the needed state. Error rows are still not retried or cleaned up automatically. Refs ClickUp 86bbxj6de
📝 WalkthroughWalkthroughThe pull request normalizes missing Dropbox URLs and adds exponential backoff for pending media uploads. Upload processing now allows five attempts, preserves retryable partial status, and logs exhausted failures at error level. ChangesFile URL normalization

Capture and restore the pending-upload checkpoint before setting Processing.
processPendingMediaUploads sets STATUS_PROCESSING before reading $currentStatus. DoctrinePendingMediaUploadRepository::getPendingUploads() excludes Processing, so a non-exhausted failure before the next checkpoint leaves the row unselectable until resetStuckProcessingRows(10) resets it. The assignment also changes partial rows to Processing, which can repeat completed storage phases. Save the checkpoint first, use it for phase selection, update it after each successful phase, and restore it on retryable failure. Add regressions for failures before public storage and after public storage succeeds but private storage fails.
