Step 3 of specs/dot_alfred.md. Concrete TVShowRepository
implementation reading and writing per-show .alfred YAML files under
a configurable library_root. Writes are atomic (.alfred.tmp +
os.replace), reads tolerate corrupted/wrong-schema sidecars (log +
skip), and the repo never invents a folder name — save(show)
requires the target folder to exist beforehand (raises
ShowFolderUnknown otherwise), matching the spec's
MediaOrganizer-then-sidecar split.
Cold folders without a sidecar are skipped by find_all and yield
None from find_by_imdb_id — the upcoming rescan_show tool (step 4)
will own the opt-in rebuild path.
A small bridge module translates between the rich domain TVShow
(AudioTrack/SubtitleTrack with full ffprobe minutiae) and the
compact sidecar shape (language-only audio, embedded-only subs with
type derived from is_forced). The bridge is intentionally lossy on
probe details the sidecar does not store, per the spec's
factual-only philosophy.
20 integration tests on tmp_path: round-trip save/find,
cold-folder/unknown-id returns, find_all skipping
(corrupted/schema-violating sidecars), delete/exists, atomic write
(no .alfred.tmp leftover), overwrite, and folder-name fallbacks
(get_folder_name guess + full-scan rescue when renamed).
