|
||
<p>A thread already holding one of these may only acquire a lock that appears
|
||
<strong>later</strong> in this list. The order is not arbitrary — it follows the nesting
|
||
the code already relies on:</p>
|
||
<ul>
|
||
<li><code>repository</code> and <code>sleep_timer</code> are taken by long-running decisions that go
|
||
on to consult playback state, so they sit outermost.</li>
|
||
<li><code>backend</code> outranks <code>queue</code>: “what is playing” is read before “what is
|
||
next”, never the reverse.</li>
|
||
<li><code>event_emitter</code> is last. Emitting is a leaf — notifying the frontend must
|
||
never reach back for more player state.</li>

</ul>
