Auto-tune channels can now carry per-content-source rotation weights (weighted
round-robin, e.g. 3x Show A / 1x Show B) and query corrections (exclude /
add-untagged), supplied at bulk-create time via an optional
`sources: [{sourceId, weight, excluded}]` on each AutoTunedChannelRequest.
Design (Option A, reuse #70): when a source is customized the channel is backed
by a system-owned MultiCollection of per-source SmartCollections carrying the
weights, with PlaybackOrder.WeightedShuffle -- the exact path
WeightedShuffleCollectionEnumerator already consumes. All-default weights keep
the #69 single-SmartCollection fair-share shape.
- Discriminators: TV -> live show_title:"X" (episodes carry no parent-show id in
the index); movies -> stable id:{mediaItemId}.
- Materialization is axis-dependent: TV materializes every base show individually
(un-weighted shows keep per-show fair-share) + a live remainder at weight 1;
MovieGenre materializes only touched movies + one count-weighted remainder.
- Remainder = (base) AND NOT (materialized union excluded) -- a partition.
- New nullable OwnedByChannelId on SmartCollection + MultiCollection
(dual-provider migration); owned rows are hidden from the collection lists and
cascade-cleaned on channel delete.
Tests: AutoTuneAxisMap query/partition units; DB-backed weighted-path handler
tests (TV materialize-all, movie count-remainder, exclusion, no-customization
fallback); delete-cleanup. Docs: decisions.md, domain-model.md, api-conventions.md;
OpenAPI trio regenerated.
