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.

Auto-Tune DetailPanel backend (#385), additive half. The create request
`AutoTunedChannelRequest` gains three optional per-channel fields, all
backward-compatible (omit = PR1 behavior):
- `templateId` — overrides the batch template per channel
- `advanced` — reuses the manual Channel Builder's
`CreateChannelFromLineupAdvancedOptionsRequest` verbatim (24-field override
set, `advanced.X ?? template.X` stamp contract). Axis default fills
`PlaybackOrder` only when the caller leaves it null.
- `logo` — uploaded channel image, `Sanitized()` at the request boundary
(#283 stored-XSS defense), forwarded to `CreateChannelFromLineup.Logo`
Resolved per channel inside `CreateAutoTunedChannelsHandler.CreateOne`, so one
channel's bad override still yields a per-channel Failed/Skipped without
aborting the batch.
Per-source rotation weights + query corrections are split out to #425 (they
need a MultiCollection-of-per-source-SmartCollections redesign — #70's
WeightedShuffle reads weights only off MultiCollection join rows, and an
auto-tuned channel is one SmartCollection). Bug-initials/colour generated logo
also deferred (needs persisted Channel state + FFmpeg-pipeline wiring).
Tests: handler override-threading (per-channel wins, axis default preserved,
no-override baseline) + request `ToCommand()` logo sanitization. OpenAPI trio
regenerated. Docs: decisions.md, api-conventions.md, domain-model.md.
