Fixed two critical race conditions that prevented multi-threaded module execution: ## Bug #1: ThreadedModuleSystem::registerModule() race condition **Symptom:** Deadlock on first processModules() call **Root Cause:** Worker thread started before being added to workers vector **Fix:** Add worker to vector BEFORE spawning thread (src/ThreadedModuleSystem.cpp:102-108) Before: - Create worker → Start thread → Add to vector (RACE!) - Thread accesses workers[index] before push_back completes After: - Create worker → Add to vector → Start thread (SAFE) - Thread guaranteed to find worker in vector ## Bug #2: stillhammer::createLogger() race condition **Symptom:** Deadlock when multiple threads create loggers simultaneously **Root Cause:** Check-then-register pattern without mutex protection **Fix:** Added static mutex around spdlog::get() + register_logger() (external/StillHammer/logger/src/Logger.cpp:94-96) Before: - Thread 1: check → create → register - Thread 2: check → create → register (RACE on spdlog registry!) After: - Mutex protects entire check-then-register critical section ## Validation & Testing Added comprehensive test suite: - test_threaded_module_system.cpp (6 unit tests) - test_threaded_stress.cpp (5 stress tests: 50 modules × 1000 frames) - test_logger_threadsafe.cpp (concurrent logger creation) - benchmark_threaded_vs_sequential.cpp (performance comparison) - docs/THREADED_MODULE_SYSTEM_VALIDATION.md (full validation report) All tests passing (100%): - ThreadedModuleSystem: ✅ 0.15s - ThreadedStress: ✅ 7.64s - LoggerThreadSafe: ✅ 0.13s ## Impact ThreadedModuleSystem now PRODUCTION READY: - Thread-safe module registration - Stable parallel execution (validated with 50,000+ operations) - Hot-reload working (100 cycles tested) - Logger thread-safe for concurrent module initialization Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

* ThreadedModuleSystem Real-World Integration Test
|
|
*
|
|
* This test validates ThreadedModuleSystem with ACTUAL modules:
|
|
* - BgfxRenderer (rendering backend)
|
|
* - UIModule (UI widgets)
|
|
* - InputModule (input handling) - optional
|
|
*
|
|
* Validates:
|
|
* - Thread-safe module loading and registration
|
|
* - IIO cross-thread message routing
|
|
* - Real module interaction (input → UI → render)
|
|
* - Module health and stability under parallel execution
