Transfer Failed Retry

Use structured moviepilot_api operations only.

Required Flow

1. Call transfer.history with status=failed and locate every requested ID. Record source path/storage, destination, mode, exact identity, music type, season/episode, status, and error. Do not act on a different record.
2. If the source no longer exists or transfer-directory configuration is missing, stop for that record and report the blocker.
3. Group records only when identity and source layout prove they belong to the same movie, series, recording, or album. Same parent directory alone is not enough. Recognize once per verified group.
4. Call transfer.history.delete for each exact history ID before retrying. This operation may submit a durable record to the persistent retry scheduler instead of deleting it.
5. If the result says durable retry was accepted or rejected, that result is final for the current task. Do not call transfer.file, delete the target, or remove history/retry evidence.
6. Only when the response confirms a legacy history was actually deleted may you continue. First call media.recognize with the source path. If the result is absent or unreliable, call media.search with narrow filename/tag facts.
7. Call transfer.file with the original source/storage/mode and the verified source-native identity. Preserve season and music entity fields. For a verified complete album sharing one directory, retry the directory once, not each track as unrelated media.
8. Report accepted durable retries, successful legacy retransfers, skipped missing/configuration cases, and remaining failures separately.

Never transfer an artist entity. Never reuse one identification across records that do not form a verified group. Never report a queued durable retry as a completed file transfer.
