Voxis Forge: Rumpk Stability, NipBox Boot, and Repository Cleanup
...
- Fixed Rumpk RISC-V Trap Handler (SSCRATCH swap, align(4), SUM bit) to prevent double faults.
- Stabilized Userland Transition (fence.i, MMU activation) allowing NipBox execution.
- Restored Forge pipeline to build NipBox from source.
- Documented critical RISC-V trap mechanics in .agent/tips.
- Committed pending repository cleanup (obsolete websites) and new core modules.

Phase 37: The Glass Cage - Memory Isolation Complete
...
VICTORY: All page faults (Code 12, 13, 15) eliminated. NipBox runs in isolated userspace.
Root Cause Diagnosed:
- Kernel BSS (0x84D5B030) was overwritten by NipBox loading at 0x84000000
- current_fiber corruption caused cascading failures
Strategic Fixes:
1. Relocated NipBox to 0x86000000 (eliminating BSS collision)
2. Expanded DRAM to 256MB, User region to 64MB (accommodating NipBox BSS)
3. Restored Kernel GP register in trap handler (fixing global access)
4. Conditionally excluded ion/memory from userspace builds (removing 2MB pool)
5. Enabled release build optimizations (reducing BSS bloat)
Results:
- Kernel globals: SAFE
- User memory: ISOLATED (Sv39 active)
- Syscalls: OPERATIONAL
- Scheduler: STABLE
- NipBox: ALIVE (waiting for stdin)
Files Modified:
- core/rumpk/apps/linker_user.ld: User region 0x86000000-0x89FFFFFF (64MB)
- core/rumpk/hal/mm.zig: DRAM 256MB, User map 32-256MB
- core/rumpk/hal/entry_riscv.zig: GP reload in trap handler
- core/rumpk/core/ion.nim: Conditional memory export
- core/rumpk/libs/membrane/ion_client.nim: Local type declarations
- core/rumpk/libs/membrane/net_glue.nim: Removed ion import
- core/rumpk/libs/membrane/compositor.nim: Stubbed unused functions
- src/nexus/builder/nipbox.nim: Release build flags
Next: Fix stdin delivery to enable interactive shell.

feat(rumpk): Phase 8 - The Summoning (ELF Loader) - 95% Complete
...
## Major Features
### 1. Dynamic ELF64 Binary Loading
- Implemented ELF parser with full header validation (core/loader/elf.nim)
- Created kexec() loader supporting PT_LOAD segment mapping
- Added BSS initialization and data copying from VFS
- Assembly trampoline (rumpk_enter_userland) for userland entry
### 2. Syscall Infrastructure
- Added CMD_SYS_EXEC (0x400) for consciousness swapping
- Integrated exec command in NipBox shell
- Implemented syscall routing through command ring
- Added provenance tracking via SipHash
### 3. Test Binary & Build System
- Created hello.c test program for alien binary execution
- Automated compilation and initrd inclusion in build.sh
- Added libnexus.h header for standalone C programs
### 4. VFS Integration
- Implemented TarFS file cursor system for sequential reads
- Fixed infinite loop bug in cat command
- Added debug logging for VFS mount process
## Technical Improvements
### Memory Management
- Fixed input ring null pointer dereference
- Implemented CMD_ION_FREE syscall for packet reclamation
- Resolved memory leak in input/output pipeline
- Added FileHandle with persistent offset tracking
### ABI Stability
- Split kprint into 1-arg (Nim) and kwrite (C ABI)
- Fixed cstring conversion warnings across codebase
- Corrected RISC-V assembly (csrw sie, zero)
### Documentation
- Comprehensive Phase 8 documentation (docs/PHASE-8-ELF-LOADER.md)
- Detailed implementation notes and debugging status
## Current Status
✅ ELF parser, loader, and syscall infrastructure complete
✅ Test binary compiles and embeds in VFS
✅ Shell integration functional
🔧 Debugging command ring communication (syscall not reaching kernel)
## Files Changed
Core:
- core/loader.nim, core/loader/elf.nim (NEW)
- core/kernel.nim, core/ion.nim (syscall handling)
- core/fs/tar.nim (file cursor system)
- hal/arch/riscv64/switch.S (userland trampoline)
Userland:
- npl/nipbox/nipbox.nim (exec command)
- libs/membrane/libc_shim.zig (syscall implementation)
- libs/membrane/ion.zig (command ring API)
Build & Test:
- build.sh (hello.c compilation)
- rootfs/src/hello.c, rootfs/src/libnexus.h (NEW)
- apps/subject_entry.S (NEW)
## Next Steps
1. Debug SysTable and command ring communication
2. Verify ION fiber polling of chan_cmd
3. Test full ELF loading and execution flow
4. Add memory protection (future phase)

feat(rumpk): Multi-Architecture HAL (aarch64, x86_64, riscv64)
...
TRI-ARCH SOVEREIGNTY
====================
Rumpk now supports three major architectures:
- aarch64 (ARM64): VisionFive 2, RPi, AWS Graviton
- x86_64: Standard servers, trading, banking
- riscv64: Sovereign compute, satellites, drones
DIRECTORY STRUCTURE
-------------------
hal/arch/
├── aarch64/
│ ├── switch.S # ARM64 context switch (96 bytes)
│ └── constants.nim # LR_OFFSET=11, FP_OFFSET=10
├── x86_64/
│ ├── switch.S # System V ABI switch (56 bytes)
│ └── constants.nim # RIP_OFFSET=6
└── riscv64/
├── switch.S # RISC-V LP64 switch (112 bytes)
└── constants.nim # RA_OFFSET=0
UNIFIED FIBER.NIM
-----------------
Uses Nim's 'when defined()' for compile-time arch selection:
- CONTEXT_SIZE varies by arch (56/96/112)
- RET_ADDR_INDEX points to return address slot
- Halt instruction varies (hlt/wfi)
BUILD SYSTEM
------------
./build.sh [aarch64|x86_64|riscv64]
- Default: aarch64
- Output: build/rumpk-$ARCH.elf
- Auto-selects linker script if arch-specific exists
ABI SUMMARY
-----------
| Arch | Callee-Saved | Frame | Alignment |
|----------|------------------------|-------|-----------|
| aarch64 | x19-x30 | 96B | 16-byte |
| x86_64 | rbx,rbp,r12-r15 | 56B | 16-byte |
| riscv64 | ra,s0-s11 | 112B | 16-byte |
VERIFICATION
------------
ARM64 fibers still work:
[Fiber A] I am alive! Yielding to B...
[Fiber B] Hello from B! Yielding to A...
[Fiber A] I am back! Yielding to B...
One codebase. All profiles. NIIX philosophy enforced.
