 ### Workspace Isolation

 - Throws `MissingWorkspaceContextException` if no workspace context
 - Provides `forWorkspaceCached()` and `ownedByCurrentWorkspaceCached()` query methods
 - Auto-invalidates workspace cache on model save/delete
+- Strict mode can be opted out per-model with `$workspaceContextRequired = false`
 
-### Entitlement System
+### Entitlement Cascade
 
 Features have types: `boolean`, `limit`, `unlimited`. Usage is tracked via `UsageRecord` with rolling window or monthly resets. Packages bundle features. Boosts provide temporary limit increases.
 
+When checking namespace entitlements, priority is:
+1. Namespace-level packages/boosts (most specific)
+2. Workspace-level packages/boosts
+3. User tier entitlements (for user-owned namespaces without workspace)
+
+### Backward Compatibility
+
+`Boot.php` registers class aliases (`App\Services\WorkspaceManager` etc.) for backward compat with code that uses the old `App\Services\` namespace.

 ## Coding Standards

+- **UK English**: colour, organisation, centre, behaviour, licence (noun) / license (verb)
 - **Strict types**: `declare(strict_types=1);` in every file
 - **Type hints**: All parameters and return types
 - **Pest**: Write tests using Pest, not PHPUnit syntax
 - **Flux Pro**: Use Flux components, not vanilla Alpine
 - **Font Awesome**: Use FA icons, not Heroicons
