Zero-Crash SDK Architecture
Eliminating non-deterministic process termination through managed-runtime refactoring.
Mission Briefing: The Seamless Substitution
After building the Real-Time Engine, we needed a robust Windows Control SDK. It had to be a "drop-in" replacement for the legacy vendor's C# SDK, enabling our cockpit software to switch engines with zero code changes.
High-load simulations caused the application to vanish. Because the SDK was a Hybrid Bridge, unmanaged Access Violations bypassed the .NET safety net, terminating the process without logs.
Architecture: From Fragile Bridge to Unified Protocol
Fragile & Multi-Protocol
Stable & Hardened
Hardening through Pure C#
THRIFT_SDK_INTEGRATION
Evicted SSH from the control loop. The SDK now handles all remote management via Thrift RPC. By bringing the protocol logic into the managed .NET environment, we eliminate unmanaged access violations that previously crashed the host process.
IMMORTAL_DAEMON
Real-time logic was moved to a target Systemd Service. Self-healing headers ensure the engine is always online, independent of the Windows UI state.
Ensures persistent simulation availability even after remote failures.

Results: Order from Chaos
SYSTEM_POST_MORTEM
ARCH_1Respect the Runtime Boundary
The 'no-man's land' between managed and unmanaged memory is where 90% of critical bugs hide.
ARCH_2Stateless Control, Stateful Daemons
Moving state to a target background daemon makes the UI layer simple, responsive, and resilient.
ARCH_3Silent Errors are the Loudest
A crash with no logs is a sign of architectural mismatch. Solving it requires moving the gate to a safer runtime.
