**Couverture totale** : **31/34 ✅ + 3 ⏸** (Crubit, mutation testing CI, et a2a-slimrpc upstream — tous trois bloqués sur dépendances externes).

## Validation gate (Google-grade golden path)

Avant tout merge, ces 6 commandes doivent être vertes :

```bash
cargo ci-offline              # clippy --locked --offline -D warnings
cargo xt-offline              # nextest --locked --offline
cargo deny check              # advisories + bans + licenses + sources
cargo vet                     # signed audits ok
cargo audit-machete           # zero unused deps
bun run docs:summary:check    # SUMMARY drift
```

Et idéalement (CI matrix) :
```bash
cargo check -p aphrody --target <each-of-14-targets> --locked
```

## Outils à installer (Google Mode setup)

```bash
# Supply-chain
cargo install --locked cargo-vet cargo-deny cargo-machete

# Coverage / fuzz / mutation
cargo install --locked cargo-llvm-cov cargo-fuzz cargo-mutants cargo-careful

# Cross-compile
cargo install --locked cargo-zigbuild cargo-ndk
winget install -e --id Ziglang.Zig    # zig pour zigbuild

# Reproducible / SBOM
cargo install --locked cargo-auditable

# Performance
cargo install --locked cargo-bloat cargo-criterion

# Release
cargo install --locked cargo-dist cargo-release

# Tests
cargo install --locked cargo-nextest cargo-hack cargo-udeps

# Pre-commit
pipx install pre-commit && pre-commit install
```

## Roadmap restante (hors-scope automatisable)

1. **Audits cargo-vet réels** — convertir les exemptions auto en `safe-to-deploy` après review crate par crate (humain, ~70 deps).
2. **Premier `cxx::bridge` réel** — quand un binding C++ non trivial est introduit dans le projet.
3. **Mutation testing en CI** — coût compute élevé, attendre que la base de tests soit étoffée.
4. **a2a-slimrpc ré-intégré** — bloqué upstream `agntcy-slim-mls` (nightly lifetime issue).
5. **path-bases stable** — attendre Cargo 1.98+.
6. **Crubit Chromium** — suivre `crbug/470466915`, adopter quand officiel.
