Darwin TUN Kernel Queue Overflow Backoff & Lossless Retry
- Handled ENOSPC / ENOBUFS when writePackets overflows, prepending unwritten packets back to the head of the transmit queue to prevent silent packet drops and stall.
- Capped kernel packet batch size to 32 and scheduled a 2ms async backoff delay to allow the Darwin driver to drain hardware buffers.
- Automatically recreates clean URLSession instances on network topology changes, preventing false-positive proxy fallback caused by stale connection pools.
Rigorous Physical Hardware & VM Matrix Verification
- Verified on physical Apple Silicon Mac mini: 10.4 Gbps line-rate throughput, 0 packet loss across 10,000 UDP datagrams, 100% pass on protocol and extension tests.
- Verified across all 6 engine/routing modes in Tart VM (aether-diag-1434) with 100% pass rate and clean environment cleanup.
Security Compliance & Release Standards
- Built with standard production core, signed with Apple Developer ID, and double-notarized by Apple (App + DMG stapled), fully compatible with macOS 15+ Apple Silicon.
