# Plan d'amélioration technique - obiskio
## 1. Contexte et objectifs
- **Objectif** : Renforcer la robustesse, la maintenabilité et les performances de la crate `obiskio`.
- **Priorités** :
1. Gestion des erreurs
2. Optimisation de la mémoire du pool
3. Robustesse concurrente
4. Couverture de tests
5. Documentation
---
## 2. Axes d'amélioration détaillés
### 2.1 Gestion des erreurs
- **Problème** : `SKError` ne couvre pas tous les cas (format invalide, taille maximale, CRC)
- **Actions** :
- Ajouter variante `ParseError(String)` dans `src/error.rs`
- Valider les tailles de SuperKmer avant parsing
- Remplacer `expect()` par `unwrap_or_else` avec messages explicites
- Documenter chaque variante d’erreur dans le README
### 2.2 Optimisation du pool de fichiers
- **Problème** : `SKFilePool` utilise un `Vec<WriteEntry>` non contraint et n’effectue pas de nettoyage en cas d’erreur
- **Actions** :
- Implémenter un `LimitedVec` avec limite stricte à `MAX_POOL_SIZE`
- Créer `clear_memory()` qui supprime les entrées orphelines
- Ajouter `evict_lru_threshold()` pour éviction proactive
- Introduire un `RwLock` pour les opérations de lecture massives
### 2.3 Robustesse concurrente
- **Problème** : Risque de deadlocks dans `SKFileWriter::write_batch()` et `SKFileReader::reopen_and_seek()`
- **Actions** :
- Remplacer `Mutex` par `RwLock` pour les accès en lecture
- Ajouter un compteur de blocage et logs de timeout
- Utiliser `std::thread::park_timeout` pour débloquer
- Insérer `debug_assert!` sur les états invariants
### 2.4 Couverture de tests
- **Problème** : Absence de benchmarks, de tests de migration, de résilience de fichiers corrompus
- **Actions** :
- Benchmarks I/O sur 10k+ SuperKmer avec `criterion`
- Tests de migration de version de fichier `.meta``.v2.meta`
- Tests de corruption volontaire (truncature, inversion de bits)
- Tests de stress sur pool saturation (100 threads)
### 2.5 Documentation & exemples
- **Actions** :
- Ajouter des examples dans chaque module (`# Examples`)
- Documenter la logique LRU avec diagrammes Mermaid
- Créer un guide « How to recover from eviction »
- Mettre à jour le `README.md` avec tableau des variantes d’erreur
---
## 3. Plan d'exécution (Roadmap)
| Sprint | Durée | Livrables clés |
|--------|-------|----------------|
| **S1** | 2 jours | Refactorisation `SKError`, ajout de tests unitaires |
| **S2** | 3 jours | Implémentation `clear_memory()` + `LimitedVec` |
| **S3** | 2 jours | Passage à `RwLock`, ajout de compteurs de blocage |
| **S4** | 2 jours | Benchmarks + tests de migration |
| **S5** | 1 jour | Documentation finale & mise à jour du README |
---
## 4. Dépendances externes
- Mettre à jour `niffler` vers la version 2.0 (performance compression)
- Évaluer `bincode` vs `serde_json` pour les métas (I/O)
- Ajouter dépendance `criterion` (dev‑dependencies)
---
## 5. KPI de suivi
- **Couverture de tests** : ≥85 % des chemins critiques
- **Latence moyenne d’écriture** : ↓15 % après optimisation du pool
- **Taux d’erreurs résolues** : 100 % des nouvelles variantes couvertes
- **Temps de build CI** : ≤5 min pour l’ensemble des benchmarks
---
## 6. Validation finale
- Revue de code avec `cargo clippy -- -D warnings`
- Analyse de toxicité avec `cargo deny open-source-licenses`
- Vérification de la conformité aux standards de naming du projet

name: No architectural decisions without explicit authorization
description: Never make architectural or design decisions without explicit user approval — code decisions are the user's alone
type: feedback
---
Never make architectural decisions unilaterally. This includes:
- Memory layout or footprint changes
- Algorithm or data structure choices (HashSet vs streaming, etc.)
- Dependency additions or substitutions
- Structural refactors that go beyond the exact task requested
If a bug or inefficiency is observed, **report it and propose alternatives** — do not fix it without explicit authorization.
**Why:** The user optimizes for minimal memory footprint at all times. Introducing a HashSet in `count_kmer()` (replacing the intended streaming GOFunction construction from the sidecar estimate) caused a serious memory regression that went unreported. This is inadmissible on a project where memory efficiency is a core constraint.
**How to apply:** When editing code and noticing an architectural issue (even a clear improvement), stop, describe the problem and options, and wait for explicit go-ahead before touching anything.

metadata:
type: feedback
---
Ne jamais qualifier les phases intra-partition de "séquentielles". Chaque phase (graph build, compute_degrees, unitig traversal, MPHF build) utilise Rayon en interne et s'exécute en parallèle sur plusieurs cœurs.
**Why:** L'utilisateur a corrigé ce point plusieurs fois. Le décrire comme "séquentiel" est une erreur factuelle qui fausse l'analyse de performance.
**How to apply:** Quand on analyse l'efficacité CPU ou les 25% manquants, chercher la cause dans le déséquilibre de charge entre partitions, la contention Rayon entre workers, ou la latence inter-partitions — pas dans une prétendue sérialisation des phases.
