fix(webapp): release the next track's preload on sign-out - #330
The player loads the track after the current one into a second <audio> element, preloader, so that skipping starts at once. #329 made the unmount cleanup of PlayerProvider pause and empty the playing element. It left the preloader alone, though, and after sign-out that element still held its source and could still be fetching it, for an account that had just left.
The same unmount cleanup now also removes the preloader's src, calls load() and drops the ref. The preload effect already creates a fresh element when the ref is empty (preloader.current ?? new Audio()), so StrictMode and Fast Refresh replays keep working.
Test
releases the next track's preload when the listener signs out in webapp/e2e/studio-nocturne.spec.ts:
records every media element asked to load();
answers each track's stream ticket with its own URL and serves a silent WAV;
plays album-2 and waits until a source is held while Cocoon is being preloaded;
signs out and polls until no recorded element keeps a src.
Inversion: run against a fresh webapp/dist built from main, it fails at the last poll with ["/api/v2/stream/ticket-song-2"] still held (Cocoon's preload). With the fix it passes.
Checks
The bundle was rebuilt before every Playwright run. The runs used port 4199 through an uncommitted local config.
bun --cwd=webapp run build: ok
biome check .: no errors (the 10 warnings were already there)
vitest: 29 files, 235 tests passed
full Playwright suite: 277 passed, 18 skipped (desktop-only tests on the mobile project), 1 failed: lists what needs attention, splits a credit on the second click, and undoes it. That one is unrelated to the player and was green in the previous full run. It timed out on its default 5 s while the machine was loaded (that run took 5.2 min against 3.7 min before), and it passed 10 out of 10 when run alone with --repeat-each=5 on both projects.

Corrections
À la déconnexion, le lecteur libère également la source audio préchargée du morceau suivant, en complément de la source du lecteur principal. Les médias préchargés ne conservent ainsi plus leur source après la fermeture de la session, y compris lorsque le préchargement de la piste suivante a déjà commencé.
The player loads the track after the current one into a second audio
element so that skipping starts at once. Unmounting PlayerProvider
emptied the playing element but left this one holding its source, and
possibly still fetching it, for an account that had just signed out.
The unmount cleanup now empties it and drops the ref; the preload
effect makes a fresh one on the next mount.
The Playwright test records every element asked to load, signs out
while the next track is preloaded, and asserts that none keeps a
source. It fails without the fix.

Summary
Nettoyage au démontage et validation webapp/src/player/player.tsx, webapp/e2e/studio-nocturne.spec.ts
Au démontage, PlayerProvider supprime la source du préchargeur, appelle load() et réinitialise preloader.current. Le test E2E vérifie qu’aucun élément suivi ne conserve de source après la déconnexion.
InstaZDLL/waveflow-server#329 — Cette PR nettoie l’élément audio principal au démontage de PlayerProvider. La présente PR applique un nettoyage similaire à l’élément de préchargement.
Merge Risk: Minimal · up to 3efd3

Before / after behavior
observed — Modified behavior in webapp/src/player/player.tsx: Le nettoyage au démontage supprime maintenant la source du prochain titre préchargé, appelle load(), puis remet preloader.current à null. Auparavant, ce préchargeur n’était pas nettoyé dans ce bloc.
observed — Modified behavior in webapp/e2e/studio-nocturne.spec.ts: Ajout d’un test E2E desktop qui suit les éléments média chargés, attend le préchargement de la piste suivante de l’album, puis vérifie qu’après déconnexion et redirection vers /login, aucun élément suivi ne conserve de source.

Explanation
Le titre « fix(webapp): release the next track's preload on sign-out » décrit précisément le changement principal : la libération de la source du préchargement lors de la déconnexion. Il est court, à une seule phrase, et correspond aux modifications de player.tsx et du test E2E.
Full details: Description check
Explanation
La description couvre le contexte (#329, préchargeur qui conservait sa source après la déconnexion), les changements, le test ajouté et une liste de vérifications exécutées. Elle ne suit toutefois pas le modèle du dépôt : il manque une section « Summary » distincte (un ou deux phrases avec lien vers les issues/PR), la case « Test plan » n'utilise pas les cases à cocher du modèle (typecheck, lint, format:check, build, test, smoke manuel), et la section « Notes » ainsi que la confirmation AGPL-3.0-only / DCO sont absentes. La description est néanmoins presque complète sur le fond.
Resolution
Ajouter les éléments suivants pour respecter le modèle : une section « Summary » courte avec un lien vers #330 et #329 ; cocher les étapes du « Test plan » du modèle (typecheck, lint, format:check, build, test) ; indiquer le smoke test manuel ou son absence ; ajouter la confirmation de licence AGPL-3.0-only et de signature DCO (git commit -s).

The playing element is asked to load too, so waiting for any held source could let the sign-out run before the next track's preload existed. The test now waits for Cocoon's own source.
