Chaîne de résolution metadata (local, Open Library, Google Books, BNF)
avec activation/priorité/clé API par provider, colonnes isbn13 et
identifiers sur les livres, et intégration au scanner pour compléter
métadonnées et jaquettes manquantes. Module automation: réglages
persistés, planifications scan/enrichissement et déclenchement manuel,
exposés via des endpoints admin.

Subject: [PATCH 11/53] fix(api): migrations idempotentes pour bases existantes
 (metadata/automation)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Les colonnes metadata_source_config et automation_settings sont
désormais ajoutées par ALTER TABLE conditionnels sur les bases déjà
initialisées, l'index books_isbn13_idx est créé via le chemin de
migration, et un test couvre la base de données existante.

Validation des chemins externalisée (library-path) avec codes d'erreur
explicites, support d'alias LIBRARY_PATH_ALIASES pour traduire un chemin
hôte vers le montage conteneur, rejet des doublons de chemin entre
bibliothèques, documentation README/.env.example et docker-compose
paramétrable via READABOOK_LIBRARY_HOST_PATH.

La création d'une bibliothèque déclenche un scan initial avec état de
réessai en cas d'échec; suppression des fallbacks mock sur create/scan
pour ne masquer aucune erreur réelle.

Régression worker PDF : le worker pdf.js est désormais instancié une
seule fois via un port dédié (?worker&url) et reconfiguré à chaque
montage, au lieu d'un workerSrc recalculé qui cassait le rendu.

- ReaderShell : chrome commun aux lecteurs (toolbar, zones de tap,
  statut) et contrat ReaderControls pour EPUB/PDF/CBZ
- préférences de lecture par livre (mode horizontal/vertical, fit) :
  table reader_preferences + migrations idempotentes, module API,
  DTO partagés, client web avec fallback localStorage hors-ligne

- nouveau use-case ScoreMetadataMatch : tri des résultats par score de
  correspondance avant sélection du meilleur candidat
- providers (google-books, open-library, bnf, local) durcis et nourris
  par les hints ; colonne + index local_metadata_json avec migrations
  idempotentes (création et rebuild legacy)
- web : nettoyage de la description de la fiche livre
  (cleanBookDescription, white-space pre-line)

 pilotage de l'enrichissement
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Adaptateurs comic-vine et mangadex avec helper de fetch partagé,
  timeouts et fallback durcis sur les providers existants
- Scoring des correspondances amélioré, normalisation de la date de
  publication, chaîne de résolution des providers étendue
- Scanner : statuts par livre (scan/enrichissement) et page admin
  d'automatisation alignée

- Rendu PDF via module dédié pdfRender (worker), correction des pages
  blanches et gestion des timeouts de rendu
- Lecteur comics : crop plein écran, locators de page unifiés (pdf/cbz/cbr)
  avec ancrage pour le calcul de progression
- Sauvegarde de progression mise en file (queueSave) pour éviter les
  pertes lors des navigations rapides
- nginx/vite : en-têtes et proxy alignés pour le streaming des livres

Subject: [PATCH 24/53] =?UTF-8?q?fix(web):=20lecteur=20PDF=20=E2=80=94=20p?=
 =?UTF-8?q?ages=20blanches=20apr=C3=A8s=20rendu=20et=20base=20minimale=20s?=

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Le canvas PDF restait vide après rendu (blank-detected): la détection d'encre
reposait sur un seuil de blanc trop sensible et un fond de canvas non maîtrisé.
Le rendu passe à un fond sentinel explicite avec classification
rendered-ok/blank-detected et un seuil de pixels visibles.

Le lecteur est par ailleurs ramené à une base minimale stable: layout plein
viewport (app-main-reader), suppression des modes de lecture et des préférences
par livre, helpers de pagination/viewport extraits dans readerLayout.ts. Shell,
lecteurs CBZ/EPUB et styles alignés sur cette base.

 ReadaBook est une application locale-first pour cataloguer, rechercher et lire une bibliothèque personnelle de livres EPUB/PDF stockés sur disque. Le MVP livré vise un usage domestique : un administrateur déclare un dossier local, lance un scan, puis les livres deviennent accessibles via un catalogue web et une API locale.
 
+## Dépôt distant
+
+Le dépôt est hébergé sur un Gitea self-hosted et peut être cloné via :
+
+```bash
+git clone https://gitea.anthonybouteiller.ovh/blomios/ReadaBook.git
+```
+
+Le déploiement git suit un git-flow simplifié : `main` (releases), `develop` (intégration), `feature/*` / `fix/*` (travail en cours).
+
 ## Fonctionnalités MVP présentes
 
 - Backend NestJS/Fastify exécutable avec healthcheck `GET /healthz`.
