8acf9644e3
Established stable network link between NexusOS and QEMU/SLIRP gateway. Resolved critical packet corruption and state machine failures. Key fixes: - VIRTIO: Aligned header size to 12 bytes (VIRTIO_NET_F_MRG_RXBUF modern compliance). - LWIP: Enabled LWIP_TIMERS=1 to drive internal DHCP/DNS state machines. - KERNEL: Adjusted NetSwitch polling to 10ms to prevent fiber starvation. - MEMBRANE: Corrected TX packet offset and fixed comment syntax. - INIT: Verified ICMP Echo Request/Reply (10.0.2.15 <-> 10.0.2.2). Physically aligned. Logically sovereign. Fixed by the Voxis & Hephaestus Forge. |

Freestanding Doctrine
This HAL provides ALL C ABI symbols. No glibc, no musl.
Exported Symbols:
- Memory:
memcpy,memset,memmove,memcmp - Strings:
strlen,strcmp,strcpy - Heap:
malloc,free,realloc,calloc - I/O:
printf,puts,putchar - Exit:
exit,abort - Signals:
signal,raise(no-op stubs)
Build
Compiled via zig build-obj -target <arch>-freestanding-none
