+# Spec Delta — game-server / integrations capability
+
+## ADDED Requirements
+
+### Requirement: EnhancedGameServer top-of-stack bootstrap
+
+The `@suaveplan/game-server` package SHALL expose an `EnhancedGameServer`
+class under the `./integrations/enhanced-server` subpath export that
+bootstraps the canonical engine + plugin stack via a single
+`bootstrap(options)` entry point.
+
+#### Scenario: Bootstrap installs all eight plugins
+
+- **WHEN** `bootstrap()` is invoked with valid options
+- **THEN** a `GameLoop`, `PluginManager`, and `GameEngine` SHALL be
+  constructed and wired
+- **AND** all eight built-in plugins (`ABTestPlugin`, `AnalyticsPlugin`,
+  `FeatureFlagPlugin`, `LoggingPlugin`, `PersistencePlugin`, `RulesPlugin`,
+  `WorkflowPlugin`, and one further reserved slot satisfied by
+  `BasePlugin` derivatives) SHALL be installed in dependency order via
+  `PluginManager.installAll`
+- **AND** the `GameEngine` SHALL be returned ready to `start()`.
+
+#### Scenario: Double bootstrap rejected
+
+- **WHEN** `bootstrap()` is invoked twice on the same `EnhancedGameServer`
+- **THEN** the second call SHALL throw `GameServerError` with code
+  `GAME_SERVER.ALREADY_BOOTSTRAPPED`.
+
+#### Scenario: Plugin install failure rolls back
+
+- **WHEN** any plugin install fails during `bootstrap()`
+- **THEN** the failure SHALL be wrapped as `GameServerError` with code
+  `GAME_SERVER.BOOTSTRAP_FAILED`
+- **AND** the underlying `cause` SHALL be the original error.
+
+#### Scenario: Lifecycle deferral
+
+- **WHEN** the caller invokes `start()` / `tick()` / `stop()` / `dispose()`
+- **THEN** the `EnhancedGameServer` SHALL delegate to the underlying
+  `GameEngine` so existing engine lifecycle codes propagate unchanged.
+
+#### Scenario: Injected dependencies are honoured
+
+- **WHEN** `bootstrap(options)` is invoked
+- **THEN** every plugin SHALL receive the injected `Clock` and
+  `LoggerLike` so deterministic tests observe stable timestamps and
+  captured logs.
