- Add queue-based matchmaking with Elo-proximity and 10s timeout
- Procedural sound engine (SFX, voice announcer, 4-track music)
- Sprite system refactored into 6 archetypes (standard, lobster, sheep, cyborg, blob, tank)
- 42+ fight choreographies with themed/generic/wild card selection

+description: Run tests or create test coverage for Archipelago
+disable-model-invocation: true
+allowed-tools: Read, Edit, Write, Glob, Grep, Bash
+argument-hint: "[area: backend|frontend|all] or [specific-file]"
+---
+
+Run or create tests for $ARGUMENTS.
+
+## Backend Testing (Rust)
+
+### Run existing tests
+```bash
+# On dev server (never build Rust on macOS)
+sshpass -p 'EwPDR8q45l0Upx@' ssh -o StrictHostKeyChecking=no archipelago@192.168.1.228 \
+  'source ~/.cargo/env && cd ~/archy/core && cargo test --all-features 2>&1'
+```
+
+### Creating new tests
+- Place unit tests in the same file with `#[cfg(test)]` module
+- Place integration tests in `core/{crate}/tests/`
+- Use `#[tokio::test]` for async tests
+- Mock external dependencies (filesystem, network, Podman)
+- Test error cases, not just happy paths
+- Aim for >80% coverage on core logic
+
+### Priority areas needing tests
+1. RPC endpoint handlers (core/archipelago/src/api/)
+2. Manifest parsing (core/container/src/manifest.rs)
+3. Dependency resolver (core/container/src/dependency_resolver.rs)
+4. Auth flows (core/archipelago/src/auth.rs)
+5. Secrets manager (core/security/src/secrets_manager.rs)
+6. Port allocation (core/container/src/port_manager.rs)
+
+## Frontend Testing (Vue/TypeScript)
+
+### Setup (if not already configured)
+Ensure vitest is configured in `neode-ui/`:
+```bash
+cd neode-ui && npm run test 2>&1 || echo "No test script configured"
+```
+
+### Creating new tests
+- Use Vitest + @vue/test-utils
+- Place tests in `neode-ui/src/__tests__/` or co-located `*.test.ts`
+- Test stores (Pinia) with `createTestingPinia()`
+- Test API clients with mocked fetch
+- Test component rendering and interactions
+- Test routing guards
+
+### Priority areas needing tests
+1. Pinia stores (app.ts, container.ts, appLauncher.ts)
+2. RPC client (api/rpc-client.ts) — error handling, retry logic
+3. WebSocket client (api/websocket.ts) — reconnection
+4. Router guards — auth flow, session timeout
+5. Key components — ContainerStatus, SpotlightSearch
+
+Report test results and any new tests created.
