## Phase 17 — Player-Bar Queue View: Wave 17.1 — Engine additions + shared QueueList (landed 2026-06-19)
**Landed:** 2026-06-19 on dev.
- **What:** The queue-engine additions and the shared presentational list component that waves 17.2 and 17.3 will consume. No player-bar wiring, overlay, embed, or Add-to-Queue affordance landed — those remain in waves 17.2 and 17.3.
- **Why:** Wave 17.1 is the cold-start prerequisite for the full Phase 17 queue-view surface. The engine additions are interop-free state mutations that land without any UI decision being made; `QueueList` is the single presentational "view" both the docked overlay and the embedded panel will share (one source, multiple views), so it is cleanest to build and test it before the hosting contexts exist.
- **Shape:**
- **Engine — `Move(int fromIndex, int toIndex)`** (`IQueueService` / `QueueService`): reorders `Items` in-place, adjusts `CurrentIndex` so the same track stays current across the move, re-emits `QueueChanged`. Never re-streams or interrupts the playing track. No-op (no `QueueChanged`) when either index is out of range or the indices are equal. Interop-free; safe during prerender.
- **Engine — `RemoveAt(int index)`** (`IQueueService` / `QueueService`): removes the item at `index`, adjusts `CurrentIndex` (a track before current decrements the index; a track after current leaves it unchanged; removing the current track does not stop playback — the track runs to natural end while `CurrentIndex` resolves to the new slot occupant; removing the last remaining item leaves the queue empty and dormant with `CurrentIndex == -1`). Re-emits `QueueChanged`. No-op when `index` is out of range. Interop-free; safe during prerender.
- **Engine — dormant-`Enqueue` coherence (OQ8):** `Enqueue` and `EnqueueRange` into an empty/dormant queue (`CurrentIndex == -1`) now set `CurrentIndex` to 0 so a subsequent play/skip is correct. Does **not** auto-play — add is not play. `PlayCurrent` is never called from these paths; the methods remain interop-free.
- **`QueueList.razor`** (`DeepDrftPublic.Client/Controls/QueueList.razor`): purely presentational component. Renders `Items` as an ordered list with the current track marked (position number + `GraphicEq` now-playing icon on the current row). `Editable` flag gates drag-reorder handles and per-row remove controls: when `true`, wraps rows in a `MudDropContainer`/`MudDropZone` for reorder; when `false`, renders a plain `<div>` (read-only; the embed's fixed-order shared queue). Reorder, remove, and row-jump are surfaced to the parent as `EventCallback<(int FromIndex, int ToIndex)> OnReorder`, `EventCallback<int> OnRemove`, and `EventCallback<int> OnJump` respectively — the component calls no `IQueueService` method itself. Owns no data fetch or player wiring. Runs during prerender without JS interop (drag work is client-only and inert when no drag occurs).
- **`QueueServiceTests`**: T1–T10 added, covering `Move` (in-range, out-of-range, same-index no-ops; current-track identity preserved across reorders) and `RemoveAt` (before/after/at current; last-item dormant; out-of-range no-op; playback not stopped).
