- Rumpk Core: Complete exorcism of LwIP/NET ghosts. Transitioned to ION nomenclature. - ABI Sync: Synchronized Zig HAL and Nim Logic Ring Buffer layouts (u32 head/tail/mask). - Invariant Shield: Hardened HAL pipes with handle-based validation and power-of-2 sync. - Immune System: Verified Blink Recovery (Self-Healing) with updated ION Control Plane. - NexShell: Major refactor of Command Plane for Sovereign Ring access. - Architecture: Updated SPEC files and Doctrines (Silence, Hexagonal Sovereignty). - Purge: Removed legacy rumk and nip artifacts for a clean substrate. - Web: Updated landing page vision to match Rumpk v1.1 milestones. |

Rumpk HAL (L0)
Language: Zig + Assembly
Purpose: Hardware Abstraction Layer
Module Index
| File | Purpose |
|---|---|
main.zig |
Entry point (_start), stack setup, calls Nim kmain |
stubs.zig |
Freestanding libc (memcpy, malloc, printf, etc.) |
uart.zig |
PL011 UART driver (QEMU virt) |
abi.zig |
C ABI structs shared with Nim |
Architecture Directory (arch/)

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
