# Architecture
`EvidencePreviewWidget` est l’adaptateur GTK unique de `EvidencePreview` pour
`CreatePersonDialog` et la fiche directe. Il encapsule les états, le rendu
EML/PDF/image/texte/vidéo, l’annulation, la génération, la garde de session et
l’arrêt du média. Les deux écrans lui transmettent uniquement une source
interne ou de staging accompagnée du SHA-256 attendu.
## Aperçu contrôlé multi-format
`EvidencePreview` vérifie l’empreinte du fichier interne ou de staging,
détecte son contenu et produit un résultat borné sans GTK. `BackgroundTask`
travaille hors du thread principal ; `CreatePersonDialog` y crée ensuite
textures, buffers et médias, rejette les générations périmées et arrête tout
média au changement ou à la fermeture. L’aperçu ne persiste rien.
Le mode aperçu de `EmlMimeExtractor` réutilise le parcours récursif et les
décodages RFC 2047/2231 sans écrire les pièces jointes. Il préfère
`text/plain`, transforme un éventuel HTML en texte inerte et retourne
l’inventaire possédé. Le contrôleur vidéo indépendant de GTK orchestre
pause, retour au début, détachement et libération via des actions injectées.

## 10. Tâches asynchrones
### 10.1 Création d’une personne avec preuves
`PersonEvidenceSelection` possède la collection ordonnée des preuves retenues
et distingue les preuves existantes des copies de staging. Il ne dépend ni de
GTK ni de SQLite. `EvidenceStaging` refuse les fichiers spéciaux et liens
symboliques, calcule l’empreinte de la source et de sa copie, détecte le MIME
et nettoie les temporaires lors d’un retrait ou d’une annulation.
`PersonCreationCoordinator` valide toutes les empreintes avant écriture, crée
la personne, importe les nouvelles preuves et rattache toute la collection
dans une transaction SQLite. Les copies définitives réalisées avant un échec
sont supprimées après rollback. `PersonCreationTask` exécute cette orchestration
hors du thread GTK. Un changement de session annule les tâches et interdit le
rafraîchissement d’une autre enquête.
Les aperçus PNG/JPEG utilisent exclusivement le fichier interne d’une preuve
existante ou sa copie de staging. PDF, vidéo, EML et autres formats ne sont
pas analysés dans cette tranche.
Les tâches longues utilisent l'infrastructure de tâche d'arrière-plan et le
gestionnaire de tâches.

# Conventions de développement
Toute vue présentant une preuve réutilise `EvidencePreviewWidget` : aucun
parsing EML/PDF ou cycle média ne doit être dupliqué dans un écran. Les
callbacks asynchrones utilisent une génération et une référence faible.
Un aperçu utilise seulement la copie contrôlée et vérifiée. La signature et
le contenu priment sur le MIME historique et l’extension. Son résultat ne
contient aucun objet GTK et un média ne démarre jamais automatiquement.

# Dépendances externes
`libjpeg` est utilisée pour le décodage borné des aperçus JPEG du ticket #109.
PNG est décodé avec Cairo. Aucun outil documentaire externe n’est lancé par
l’aperçu et aucun dérivé n’est persisté.
`libjpeg` décode JPEG, `libheif` HEIC/HEIF et Poppler GLib rend la première
page PDF du ticket #109. PNG utilise Cairo et la vidéo `GtkMediaFile` avec le
backend GTK/GStreamer. Aucun outil documentaire n’est lancé et aucun dérivé
n’est persisté.
| Fonction | Arch Linux | Ubuntu/Debian |
| --- | --- | --- |
| HEIC/HEIF | `libheif` | `libheif-dev` |
| PDF natif | `poppler-glib` | `libpoppler-glib-dev` |
| Vidéo GTK | `gst-plugins-base`, `gst-plugins-good` | `gstreamer1.0-plugins-base`, `gstreamer1.0-plugins-good` |
Les codecs vidéo supplémentaires restent optionnels.
Le Makefile vérifie explicitement GTK4, SQLite, libheif et Poppler GLib avant
compilation et renvoie vers ce document si une dépendance manque.
Ce fichier recense les outils utilisés par LabFy Investigation et leur
installation. Il sera complété à chaque intégration d’un nouvel outil.

# Guide de développement
La validation ciblée du composant partagé comprend
`test_evidence_preview_widget_gtk`, `test_evidence_preview`,
`test_evidence_video_preview_controller` et
`test_create_person_dialog_gtk`, ce dernier sous
`G_DEBUG=fatal-criticals`.
Les tests d’aperçu génèrent exclusivement des fixtures `SPECIMEN` temporaires.
Ils couvrent dispatch, limites, annulation et intégrité, puis le parcours GTK
réel avec `G_DEBUG=fatal-criticals`. Aucun aperçu ne lance OCR ou SQLite.
La fixture HEIC est une matrice RGB `SPECIMEN` encodée en mémoire par
libheif/HEVC. Le test HEIF remplace uniquement la marque compatible du
conteneur synthétique. Les transformations d’orientation libheif restent
appliquées par le décodage standard ; seule l’image principale est rendue et
le nombre d’images de premier niveau est exposé.

# Roadmap
La tranche 2 partage désormais l’aperçu entre l’assistant personne et la
fiche directe. La validation manuelle des codecs installés reste nécessaire ;
elle ne vaut pas achèvement du ticket #109 et n’inclut aucun OCR.
L’aperçu contrôlé du ticket #109 couvre PNG/JPEG, HEIC/HEIF, MP4/MOV, texte,
EML passif et première page PDF. OCR et analyse avancée restent hors périmètre.

La tranche 1 du ticket #109 couvre les rôles contextuels multiples, la
sélection d’une preuve existante, la création transactionnelle et la garde de
session. Import intégré, PDF, vidéo, EML avancé, OCR et documents d’identité
restent hors périmètre.
Les tranches 1 et 2 du ticket #109 couvrent les rôles contextuels multiples,
la sélection de plusieurs preuves existantes, le staging et l’import multiple
différé, ainsi que la création transactionnelle avec compensation des
fichiers. OCR, extraction de documents d’identité et analyses documentaires

# Test manuel — ticket #109, tranche 2
Comparer le même EML synthétique dans la fiche directe et dans l’assistant :
From, To, Cc, Date, Subject, Message-ID, corps et inventaire détaillé des
pièces jointes doivent être identiques. Tester ensuite PNG/JPEG/HEIC/HEIF,
PDF, MP4/MOV et texte, les changements rapides, la fermeture pendant
chargement ou vidéo, la réouverture et l’ouverture d’une fiche personne.
Vérifier l’absence de critique GTK, d’écriture SQLite et d’OCR.
Utiliser exclusivement une enquête temporaire et des fichiers synthétiques
dont le nom ou le contenu porte `SPECIMEN`.
1. Créer une enquête temporaire et y importer préalablement deux preuves
synthétiques PNG/JPEG.
2. Ouvrir « Ajouter une personne », renseigner une désignation fictive et
sélectionner plusieurs rôles.
3. Dans « Preuves », rechercher puis ajouter les deux preuves existantes.
Vérifier qu’un second ajout est refusé sans modifier la preuve.
4. Choisir « Importer des fichiers » et sélectionner simultanément un PNG, un
JPEG et un PDF synthétiques. Vérifier que rien n’apparaît encore dans
`01_Preuves_Originales` ni dans SQLite.
5. Activer chaque élément retenu. Vérifier les aperçus PNG/JPEG et le message
explicite d’indisponibilité du PDF.
6. Modifier individuellement les types métier, naviguer en arrière puis en
avant et vérifier la conservation de l’état.
7. Retirer une preuve existante et un fichier nouveau. Vérifier que la preuve
existante reste dans l’enquête et que la copie de staging retirée disparaît.
8. Sélectionner deux fois le même fichier, puis deux fichiers de même contenu.
Vérifier le message de doublon et l’unicité de la sélection.
9. Ajouter un fichier identique à une preuve existante. Vérifier la
réutilisation explicite de cette preuve.
10. Atteindre Confirmation et contrôler la liste complète, les origines,
types, MIME, tailles, empreintes abrégées et compteurs.
11. Annuler puis vérifier l’absence de nouvelle personne, preuve, rôle,
rattachement et copie définitive, ainsi que le nettoyage du staging.
12. Recommencer, puis fermer la fenêtre pendant le staging. Vérifier la
fermeture propre, le nettoyage et le maintien de l’application.
13. Recommencer et changer d’enquête pendant une préparation ou une création.
Vérifier l’annulation, l’absence d’écriture dans la nouvelle enquête et
l’absence de rafraîchissement tardif.
14. Confirmer normalement. Vérifier que toutes les preuves sont rattachées à
la personne avec une source `manual`, puis rouvrir l’enquête.
15. Comparer les empreintes des fichiers sources avant et après le parcours.
Elles doivent être identiques.
16. Vérifier qu’aucun OCR ni outil documentaire avancé n’a été lancé.
17. Ouvrir la liste des preuves disponibles, choisir successivement deux
preuves, revenir à « Aucune preuve associée », activer une recherche et un
filtre, puis sélectionner de nouveau une preuve. Vérifier l’absence de
crash et de critique GTK.
18. Ajouter une image JPEG historique synthétique dont le MIME enregistré est
NULL et le type métier `document`. Vérifier que le contenu JPEG intègre est
détecté, que l’aperçu apparaît et que « MIME détecté : image/jpeg » est
affiché sans modification SQLite.
19. Renommer un fichier texte synthétique avec l’extension `.jpg`, puis
vérifier que l’aperçu est refusé malgré l’extension. Refaire avec un MIME
historique `image/jpeg` incohérent et vérifier le même refus.
20. Modifier le type individuel de l’image de `document` vers `email`.
Vérifier immédiatement la même valeur dans la ligne retenue, le sélecteur,
les métadonnées et le résumé après un aller-retour entre les étapes.
21. Tester des fixtures PNG, JPEG, HEIC, HEIF, MP4, MOV, EML, TXT, CSV, LOG,
Markdown et PDF. Vérifier l’image, le lecteur sans lecture automatique,
le texte passif, les en-têtes EML et la première page PDF.
22. Tester format invalide, extension trompeuse et fichier trop volumineux.
23. Changer rapidement de preuve et vérifier le rejet tardif et l’arrêt vidéo.
24. Fermer puis changer d’enquête pendant un aperçu ; vérifier l’annulation.
25. Vérifier les empreintes inchangées et l’absence d’OCR, d’accès distant et
d’écriture SQLite pendant l’aperçu.
26. Avec un EML multipart synthétique, vérifier que le corps `text/plain` est
préféré au HTML et que nom, MIME, taille, disposition et Content-ID des
pièces jointes sont visibles sans fichier extrait persistant.
Limites : aucun OCR ni analyse avancée. La vidéo dépend des codecs GStreamer.
