The 2.0 card "Continue listening on Home", reworked after a first try.

From "continue listening" to a suggestion of the day

The first version showed the track the last session stopped on, with Resume at the saved position. It worked, but the player bar already shows that track, paused at that position, right under it: the card repeated it. In its place, Home now suggests one track, with the reason it was picked.

The three kinds

All read from the profile's own listening (play_event). A play counts when the track was played through or for 15 s, the recently-played list's rule.

Kind Picks Reason line
You used to love this Played at least 3 times, not once in the last 60 days; most played first "6 plays · last played in July 2026"
In your current groove By one of the 5 artists played most in the last 14 days, or an artist the similar-artists cache lists for one of them; not played in 30 days; ranked by distance to those 14 days' energy and tempo (a half or double tempo counts as the tempo itself) "Because you've been playing Civin"
Never played No play at all, one per artist (the latest added); artists played most first, then the latest added, so a new library still gets one "By Thomas Vent, whom you play often" / "Added …, never played yet"

The similar-artists cache is only read: the card makes no network call. Genres are deliberately left out for now, since tags are too uneven to weigh on their own. That may come with a genre-completion pass over the library.

Stable for the day

The draw is made among the first 20 of a kind, at most 2 per artist, from the calendar day and the number of Another suggestion clicks (waveflow_core::home_suggestion). The same pair always gives the same track, so Home does not change on every visit:

  • the kind rotates from one day to the next;
  • each click moves to the next kind, with a new draw;
  • a kind with nothing gives way to the next.

The clicks are stored per profile (home.suggestion_draw), and a new day starts over. The card is hidden when no kind has anything.

The title and the reason line have 2–3 wordings each in every locale, chosen from the draw and the track, so the card does not read the same every time.

Play

Play starts the track followed by tracks like it, through the seeded radio the track menu's Start radio already uses (start_radio).

A fix on the way

start_radio decoded primary_artist as a required id. A track whose artist was deleted (ON DELETE SET NULL), or that never named one, failed with a decode error. Such a seed now skips the similar-artist step and goes to the radio's fallback, the artists played most. This is a separate commit.

Checks

  • waveflow-core unit tests for the rotation, the stable draw, the per-artist cap and the energy/tempo distance pass locally (4 new). The app crate's tests run on the CI's Ubuntu job.
  • cargo fmt --check and cargo clippy -p waveflow -p waveflow-core --all-targets -D warnings are clean.
  • bun run typecheck and bun run lint pass.
  • Strings in all 17 locales, with the plural forms Russian and Arabic need. A script checked that every locale carries every variant.
  • Tried in the app: the three kinds and their wordings, Another suggestion, and Play.
  • Local CodeRabbit review: one finding, applied. A suggestion now shows only for the profile it was loaded for, so after a switch the outgoing profile's track never stays on screen.
  • Documented in docs/features/ui.md (Suggestion of the day) and the CLAUDE.md catalogue.

@coderabbitai review

Summary by CodeRabbit

  • Nouvelles fonctionnalités

    • La page d’accueil propose une suggestion quotidienne fondée sur l’historique d’écoute : un titre oublié, proche des goûts récents ou jamais écouté.
    • Sélectionnez « Another suggestion » pour découvrir une autre proposition. La sélection reste stable dans la journée et alterne entre les catégories disponibles.
    • Lancez une radio similaire depuis la suggestion. La carte est masquée si aucune proposition n’est disponible.
  • Améliorations

    • La radio peut démarrer à partir d’un morceau sans artiste principal.

The seed query decoded primary_artist as a required id, so a track whose
artist was deleted (ON DELETE SET NULL) or never named failed with a
decode error. Such a seed now skips the similar-artist step and goes to
the fallback, the artists played most.

📝 Walkthrough

Home affiche une suggestion quotidienne fondée sur le profil local. Le backend sélectionne une piste dans trois catégories. Le frontend conserve le tirage par profil et permet de demander une autre suggestion ou de lancer une radio.

Changes: Suggestion du jour

Layer / File(s) Summary
Règles de calcul
src-tauri/crates/core/src/home_suggestion.rs, src-tauri/crates/core/src/lib.rs
Ajout des catégories, de leur rotation, du tirage déterministe, des limites par artiste et de la mesure de proximité musicale. Des tests couvrent ces calculs.
Sélection des pistes côté backend
src-tauri/crates/app/src/commands/home_suggestion.rs, src-tauri/crates/app/src/commands/mod.rs, src-tauri/crates/app/src/lib.rs
La commande construit les listes « oubliée », « vibe » et « non écoutée » depuis le profil local. Elle renvoie une suggestion épinglée si sa piste reste disponible, sinon sélectionne une piste et expose la commande à Tauri.
Contrat frontend et état du tirage
src/lib/tauri/homeSuggestion.ts, src/hooks/useSuggestionDraw.ts
Ajout de l’appel Tauri et du contrat TypeScript. Le frontend calcule le jour local et conserve le jour, la tentative et la suggestion épinglée dans un réglage du profil.
Carte Home et lancement de la radio
src/components/views/home/HomeSuggestionCard.tsx, src/components/views/HomeView.tsx, src-tauri/crates/app/src/commands/radio.rs, docs/features/ui.md, CLAUDE.md
Home affiche une carte qui charge la suggestion, propose un autre tirage et lance la lecture. start_radio accepte l’absence d’artiste principal et poursuit son traitement de repli. La documentation décrit le comportement.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Loading
Merge Risk: 🔵 Low · up to 24415

If saving the draw fails, “Another suggestion” can revert to the previous track. This is a bounded issue, but it should be fixed or accepted before merging.

Security architecture risk: 🔵 Low · up to 24415

The change primarily uses local listening data and existing playback capabilities. Profile-scoped saves have ownership checks. No new exploitable security issue was established, but profile continuity during asynchronous loading and playback remains partly unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • observed — The inspected path reads the active profile's library and listening data, persists a draw setting, and can replace the active playback queue through existing commands. Its demonstrated authority is desktop profile data and playback; the PR does not change the inspected Tauri security configuration or capability declarations.

Trust Boundaries and Controls

  • observed — Setting writes carry the profile captured by the setting hook. The backend checks that expected identity while acquiring the profile lease under the switch lock, rejecting a write redirected by an intervening profile switch.
  • inferred — Profile continuity across radio generation and queue replacement is an inherited limitation, not an established new security regression. Home adds a caller without an expected-profile parameter, but the same two-command sequence already existed at the PR base. A switch between calls could reinterpret colliding IDs in another profile; increased attacker authority or cross-user disclosure was not demonstrated.

Resilience and Maintainability Implications

  • observed — Queue replacement deletes and inserts within one transaction and commits its cursor and related settings together. The queue schema declares a track foreign key. These are important failure-containment controls, although neither binds a returned radio ID list to its originating profile.

Hardening Proposals

  • proposed — As follow-up hardening of the existing active-profile model, carry an expected profile identity through suggestion reads and the radio-to-player handoff, validating it when each backend lease is acquired. This would make asynchronous ownership explicit rather than relying on frontend timing.

Appliquer le critère de lecture qualifiée à la fraîcheur Vibe.

Le prédicat actuel exclut tout événement récent. Un événement naturel avec completed = 0 et listened_ms < 15000 peut donc retirer un titre des candidats Vibe pendant 30 jours, alors qu’il ne compte pas comme une lecture. Utilisez QUALIFIED_PLAY_MS, comme dans les autres requêtes d’historique.

+                  AND (pe.completed = 1 OR pe.listened_ms >= ?)

Filtrer unplayed sur les lectures comptabilisées.

unplayed exclut tout play_event, même lorsqu’un événement de fin naturelle a completed = 0 et listened_ms < 15000. Le morceau est alors absent de la catégorie « Never played », bien qu’il ne constitue pas une lecture comptabilisée selon la règle de la fonctionnalité.

Utiliser la même condition que les autres requêtes de l’historique :

@coderabbitai On the two outside-diff comments (the Vibe freshness filter and the unplayed CTE): not applied, on purpose. The 15 s rule is for counting plays (a favourite's plays, an artist's plays). Leaving a track out takes any play, a skip included. With the qualified-only predicate, a track skipped two seconds in yesterday could come back as "in your current groove", or be shown as "never played" although it was started; a recent skip is the strongest sign not to suggest it. The docs made the 15 s rule read as global, which is fair to flag: 2f04e82 spells out the split, in docs/features/ui.md and on QUALIFIED_PLAY_MS.

🟡 Minor · Inclure tous les play_event dans le calcul de fraîcheur. · home_suggestion.rs:163-165

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Inclure tous les play_event dans le calcul de fraîcheur.

forgotten() filtre les lignes avant MAX(pe.played_at). La branche TrackEnded peut toutefois enregistrer une ligne avec completed = 0 et listened_ms < 15_000. Cette ligne récente est alors ignorée, tandis que les trois anciennes lectures qualifiées restent comptées. Le morceau peut donc être proposé comme oublié, contrairement au contrat « tout play exclut le morceau ».

Comptez seulement les lectures qualifiées, mais calculez MAX(pe.played_at) sur toutes les lignes :

Suggested fix
         SELECT pe.track_id, t.primary_artist, COUNT(*) AS plays, MAX(pe.played_at) AS last_played
           FROM play_event pe
           JOIN track t ON t.id = pe.track_id
          WHERE t.is_available = 1
-           AND (pe.completed = 1 OR pe.listened_ms >= ?1)
          GROUP BY pe.track_id

@InstaZDLL Merci pour la précision. Je retire mes deux remarques sur le filtre de fraîcheur Vibe et la CTE unplayed : elles appliquaient à tort la règle des 15 s aux exclusions.

Les requêtes respectent bien la distinction :

  • Comptage : lecture terminée ou durée d’au moins 15 s.
  • Exclusion Vibe : toute lecture dans les 30 derniers jours, même interrompue après deux secondes.
  • Exclusion unplayed : toute lecture, quelle que soit sa durée.

J’ai vérifié que docs/features/ui.md et le commentaire de QUALIFIED_PLAY_MS explicitent cette distinction. Aucun changement de ces deux filtres n’est nécessaire.

@coderabbitai On the outside-diff comment about forgotten(): applied in eeac386, and it is the same rule as my previous reply. The qualified filter used to apply before aggregation, so a favourite skipped three days ago still read as idle for 60 days. Now plays is a SUM over qualified plays only, while last_played is MAX(played_at) over every play, a skip included; the thresholds are unchanged. Checked on a SQLite fixture with three tracks: 4 full plays 100 days ago (kept); the same plus a 2 s skip 3 days ago (left out); 2 full plays and 3 skips (left out, under 3 counted plays).

Ne pas traiter un échec de lecture comme un tirage vide

Lors de l’initialisation ou d’un changement de profil, un échec de lecture peut laisser la valeur par défaut tout en mettant draw.ready à true. Le composant considère alors le tirage comme vide, appelle getHomeSuggestion(today, attempt, pinned) avec pinned: null, puis affiche toute suggestion réussie. Après la lecture de la piste précédente, cette requête peut sélectionner une autre piste dans l’ensemble de candidats modifié. Ce comportement viole le contrat du tirage épinglé du jour et de la tentative.

Exposez un état distinct pour l’échec de lecture. Tant que le pin existant n’est pas lu avec succès, le composant ne doit pas lancer de requête non épinglée. Un tirage réellement vide doit rester traité séparément.

Conserver le pin après un échec d’écriture

Si l’écriture de home.suggestion_draw échoue, useProfileSetting restaure DEFAULT_SUGGESTION_DRAW. HomeSuggestionCard relance alors getHomeSuggestion(today, attempt, null).

Après la lecture du morceau, le pool peut changer. La requête sans pin peut donc afficher un autre morceau pour le même profil, le même jour et le même attempt. Aucun garde ne conserve la suggestion déjà affichée.

Faites remonter l’échec de setDraw et bloquez toute nouvelle requête sans pin tant que le draw n’est pas persisté. Ce traitement est distinct de l’échec de lecture.

@coderabbitai On the two latest outside-diff comments on HomeSuggestionCard:

Failed write (lines 103-115): applied in 5fd5e36. It was worse than a flipped suggestion. useProfileSetting rolls a refused write back and broadcasts, which changed pinned and re-ran the effect. That made a new draw, a new write, a new refusal and a new rollback, looping for as long as the database refused writes. The card now keeps its own draw per profile, day and attempt in a ref, and hands it back when the stored pin is missing. After a rollback, the same track returns, and since it matches the pin that was sent, nothing is written. The suggestion on screen stays and the loop cannot start. The write failure itself is already logged by the hook ([useSuggestionDraw] write failed).

Failed read (lines 73-105): not applied. useProfileSetting reports a failed read as ready with the default value, by design for all of its consumers; telling it apart from an empty draw needs a new error state in that shared hook. A read fails for a closed pool or a profile going away, and the write behind it then fails for the same reason. In the case that remains, the cost is the day's draw starting over at the first suggestion, not data, which does not justify changing the hook's contract.

@InstaZDLL Merci pour les précisions. J’ai vérifié les deux chemins dans le code.

  • Échec d’écriture : le correctif traite la boucle décrite. drawnRef conserve l’épingle par profil, jour et tentative. Si l’épingle stockée manque après le rollback, la carte réutilise cette épingle locale. Le même morceau ne déclenche donc pas une nouvelle écriture. Le hook journalise déjà l’échec.
  • Échec de lecture : je retire cette remarque. useProfileSetting passe volontairement à ready même après un échec de lecture initiale, avec la valeur par défaut. Le risque résiduel décrit est une réinitialisation du tirage du jour, pas une perte de morceaux ou d’historique. Cela ne justifie pas de modifier le contrat partagé dans cette PR.

src/components/views/home/HomeSuggestionCard.tsx:181-191
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Conserver la tentative avancée et masquer l’ancien pin après un échec d’écriture.

Lorsque setDraw échoue, useProfileSetting restaure la valeur confirmée. Le attempt et le pinned précédents reviennent donc ensemble. HomeSuggestionCard transmet alors ce pinned restauré à getHomeSuggestion, qui peut retourner l’ancien morceau au lieu de la suggestion avancée.

Conservez localement la tentative avancée et l’identifiant du pin remplacé. Ignorez le pin restauré uniquement si la valeur persistée correspond encore à cet ancien pin. Utilisez un pin persisté différent s’il a été mis à jour indépendamment.

@coderabbitai On the outside-diff comment about handleAnother (lines 181-191): not applied, on purpose. Unlike the two previous write-failure findings, there is no loop here. After the rollback, the card asks for the restored pin, gets the same track back and writes nothing. The click is simply undone because the database refused it. That is the optimistic-UI contract useProfileSetting gives every preference in the app: paint at once, roll back when the write is refused. Keeping the click alive locally against a refused write would make this card the one exception to that contract, and add more local state for a case where the profile database is refusing writes. The loops are what had to be fixed, and 5fd5e36 and 2441566 did that.

@InstaZDLL Merci pour la précision. Je retire ma remarque sur handleAnother.

Le code confirme votre explication : après le rollback, la carte recharge l’épingle restaurée. Si le même morceau revient, elle ne lance aucune nouvelle écriture. Ce chemin ne crée donc pas de boucle.

L’annulation du clic respecte le contrat optimiste de useProfileSetting. Conserver ce clic localement n’est pas nécessaire.

Learning: Dans WaveFlow, handleAnother dans src/components/views/home/HomeSuggestionCard.tsx respecte le contrat optimiste partagé de src/hooks/useProfileSetting.ts : le clic modifie immédiatement le tirage, mais un refus d’écriture restaure la dernière valeur confirmée et annule le clic.
