What's New in CppDesk 3.6.0

• File Synchronization & Delta Streaming: Added arithmetic overflow validation and bounds checking for block indices in handleDeltaBlock and handleHashReqHost. Fixed a recursive mutex deadlock in cancelSyncLocked when processing AbortSync requests.
• Codec & Task Pipeline Synchronization: Updated worker thread synchronization in the tile pool to wait until all active tasks complete before returning, preventing buffer reuse hazards during in-flight encoding and decoding.
• Cryptographic Validation: Enforced fail-closed verification on peer NIST P-256 public key blobs during ECDH key exchange. Hardened TOTP HMAC generation against malformed secret decodes.
• Clipboard & Directory Sandboxing: Strengthened path normalization across file transfer and clipboard managers to prevent directory traversal and circular symlink escapes.
• Media & Session Recording: Added automatic RIFF AVI container finalization and audio track flushing when closing the window during an active recording. Added clamp guards against zero or negative dimensions in the rewind scrubber.
• Relay Server Connection Guards: Added duplicate Desk ID collision detection to the standalone .NET 10 relay server, ensuring active host connections cannot be hijacked.
• Windows Packaging & Version Resource: Configured Windows application manifest execution level to asInvoker for standard user startup. Added Win32 VERSIONINFO resource metadata (FILEVERSION 3,6,0,0) in cppdesk.rc and enabled resource compiler support in CMakeLists.txt.
• Automated Verification: Replaced test placeholders with deterministic post-condition assertions across all 51 test suites, with 31,603 passing assertions.
