 - [`ThreadPool`](modules/Thread/ThreadPool.mpp) - Fixed-size thread pool for parallel task execution
 - [`TryAsync`](modules/Thread/TryAsync.mpp) - Launches a function asynchronously, forwards exception to caller
-- [`UniqueLocker`](modules/Thread/UniqueLocker.mpp) - Scoped exclusive lock wrapper
+- [`UniqueLocker`](modules/Thread/UniqueLocker.mpp) - RAII wrapper holding a value with exclusive access
+- [`SharedLocker`](modules/Thread/SharedLocker.mpp) - RAII wrapper holding a value with shared/exclusive access
+- [`Accessor`](modules/Thread/UniqueLocker.mpp) - RAII accessor for reading/writing an `UniqueLocker` or exclusive access to a `SharedLocker`
+- [`ReadOnlyAccessor`](modules/Thread/SharedLocker.mpp) - RAII accessor for shared (non-exclusive) reading of a `SharedLocker`, allowing parallel access
+- [`MultipleAccessor`](modules/Thread/UniqueLocker.mpp) - RAII accessor for multiple lockers, locking them simultaneously to prevent data races
