+
+## Base
+
+Base déclarée : `0.1.0-1-alpha.2.fix.3`, non validée.
+
+## Échec observé
+
+`cargo check --workspace` et Clippy échouent dans `game-reflex-poc-tauri` :
+
+```text
+failed to resolve: use of unresolved module or unlinked crate `serde`
+```
+
+La structure `FrontendLogPayload` dérive `serde::Deserialize`, mais `serde` n'était pas une dépendance directe de la crate Tauri.
+
+## Correctif
+
+Le workspace déclare désormais :
+
+```text
+serde = { version = "1", features = ["derive"] }
+```
+
+et `game-reflex-poc-tauri` consomme :
+
+```text
+serde.workspace = true
+```
+
+Aucune autre logique du bridge logging/Escape n'est modifiée.
+
+## Validation
+
+```bash
+cargo fmt --all
+cargo fmt --all -- --check
+
+python3 scripts/audit_rust_workspace_rules.py
+python3 scripts/audit_markdown_tables.py README.md RULES.md ROADMAP.md CHANGELOG.md docs prompts crates Android deltas history
+
+cargo check --workspace
+cargo clippy --workspace --all-targets --all-features -- -D warnings
+
+cargo test -p game-logging-lib --all-targets --all-features
+cargo test -p game-reflex-poc --all-targets --all-features
+cargo test -p game-reflex-poc-wasm --all-targets --all-features
+```
+
+Puis :
+
+```bash
+python3 scripts/build_reflex_tauri_wasm.py
+cd crates/apps/game-reflex-poc-tauri
+cargo tauri dev
+```
+
+Critères fonctionnels inchangés :
+
+- logs Rust et frontend visibles dans le terminal ;
+- `Escape` traverse la politique `EngineGame::quit_requested` ;
+- décision `Exit` ferme la fenêtre Tauri proprement.
