# Delta 0.0.2-alpha.2.fix.2 — retour explicite Clippy

## Base requise

Partir de `0.0.2-alpha.2.fix.1` après application et commit du history réel :

```text
deltas/0.0.2/alpha.2.md          présent et historique
deltas/0.0.2/alpha.2.fix.1.md    présent et historique
history/0.0.2/alpha.2.md         FAIL
history/0.0.2/alpha.2.fix.1.md   FAIL
```

Les deltas historiques ne doivent pas être réécrits.

La version devient :

```text
0.0.2-alpha.2.fix.2
```

## Objet

Corriger uniquement le dernier défaut révélé par la gate opérateur de `alpha.2.fix.1` :

```text
clippy::implicit_return
crates/knowledge-git-lib/unit_tests/backend.rs:85
```

La closure de validation du `source-key` doit rendre explicitement son booléen avec `return` conformément aux lints workspace.

Le fix ne modifie aucune logique du backend Git et n'ajoute aucune capacité. `refresh`, résolution vers commit et snapshot/worktree restent réservés à `alpha.3`.

## Scope

REPLACE :

```text
VERSION
Cargo.toml
crates/knowledge-git-lib/unit_tests/backend.rs
docs/plans/002-V0_0_2_GIT_SYNC_PLAN.md
docs/validation/001-VALIDATION_MATRIX.md
```

ADD :

```text
deltas/0.0.2/alpha.2.fix.2.md
```

DELETE : aucun.

Le history `history/0.0.2/alpha.2.fix.1.md` appartient à la base requise mais n'est pas inclus dans ce delta.

Aucun fichier sous `Web/`, `crates/knowledge-git-api/` ou `crates/knowledge-sync-api/` n'est modifié. Les fichiers fonctionnels `src/backend.rs`, `src/error.rs` et `src/lib.rs` de `knowledge-git-lib` restent inchangés.

## Correction attendue

Le test `source_key_never_interpolates_raw_source_identifier_as_a_path` doit remplacer le retour implicite de la closure par un retour explicite :

```text
|character| return character.is_ascii_alphanumeric() || character == '-'
```

Aucun autre changement de comportement n'est attendu.

## Gate opérateur

Après application du history `alpha.2.fix.1`, commit/push de cet état, puis application du présent delta :

```bash
test "$(cat VERSION)" = '0.0.2-alpha.2.fix.2'
grep -F 'version = "0.0.2-alpha.2.fix.2"' Cargo.toml
grep -A2 '^## Statut$' history/0.0.2/alpha.2.fix.1.md | grep -Fx 'FAIL'

## Résultat attendu

Le point critique est :

```text
cargo clippy --workspace --all-targets --all-features -- -D warnings
```

qui doit désormais être `PASS` sans warning ni erreur.

Le test ciblé doit conserver :

```text
7 passed; 0 failed
```

Un `PASS` complet ferme `alpha.2` et autorise uniquement la préparation d'`alpha.3`.
