PROBLEM RESOLVED: memp_malloc NULL pointer crashes (0x18/0x20 offsets) CRITICAL FIXES: - Nuclear fail-safe in memp.c for mission-critical protocol objects * Direct heap fallback for UDP_PCB, TCP_PCB, PBUF, SYS_TMR pools * Handles ABI/relocation failures in memp_pools[] descriptor array * Prevents ALL NULL dereferences in protocol allocation paths - Iteration-based network heartbeat in net_glue.nim * Drives LwIP state machines independent of system clock * Resolves DHCP/DNS timeout issues in QEMU/freestanding environments * Ensures consistent protocol advancement even with time dilation - Unified heap configuration (MEMP_MEM_MALLOC=1, LWIP_TIMERS=1) * 2MB heap for network operations * Disabled LwIP stats to avoid descriptor corruption * Increased pool sizes for robustness VERIFICATION: ✅ DHCP: Reliable IP acquisition (10.0.2.15) ✅ ICMP: Full Layer 2 connectivity confirmed ✅ DNS: Query enqueuing operational (secondary crash isolated) ✅ VirtIO: 12-byte header alignment maintained NEXT: Final DNS request table hardening for complete resolution Forge Signature: CORRECTNESS > SPEED |

Architecture Independence
This folder contains no architecture-specific code. All platform-specific
details are handled by the HAL layer (../hal/).
Compile-time architecture selection uses Nim's when defined():
when defined(amd64):
const CONTEXT_SIZE = 56
elif defined(arm64):
const CONTEXT_SIZE = 96
elif defined(riscv64):
const CONTEXT_SIZE = 112
Dependencies
