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.

feat(rumpk): Phase 3.5b Zicroui HUD Integration
...
- Vision: Updated VISION.md with Zicroui TUI/GUI Hybrid strategy
- Logic Graft: Integrated microui.c directly into Rumpk kernel
- HAL: Added hal/ui.zig (Zig Adapter) and hal/framebuffer.zig (Stub)
- Build: Updated build.sh to compile microui with freestanding headers (libs/microui/include)
- Stubs: Implemented vsnprintf, snprintf, sprint, strtod, qsort in cstubs.c for microui support
- Scheduler: Added dedicated UI Fiber (The Face) to kernel.nim
- Result: Immediate Mode GUI logic running on bare metal RISC-V

feat: Initialize Rumpk Modular Unikernel
...
STRATEGIC PIVOT: From Project to Doctrine
==========================================
This commit initializes Rumpk - a ground-zero Zig+Nim unikernel with
POSIX-hostile design, hard ABI barriers, and military-grade security.
DOCUMENTATION (3 New Specs)
---------------------------
• SPEC-008-RUMPK-ARCHITECTURE.md
- L0 (Zig): Boot, PMM, IRQ, HAL
- L1 (Nim): LWKT Scheduler, Fibers, Disruptor Ring
- L2 (ABI): struct HAL function pointers (future Janus socket)
- L3 (Payload): NPL/NPK loaders, optional POSIX shim
- SipHash IDs + Ed25519 signed execution
• SPEC-009-RUMPK-IO.md
- Disruptor Ring: Lock-free O(1) inter-fiber communication
- Adaptive Governor: War Mode (polling) ↔ Peace Mode (interrupts)
- Zero VM-exit design (Rumkv does NOT touch packets)
• SPEC-010-SOVEREIGN-HIERARCHY-V2.md
- /Cas: Immutable Content-Addressable Storage
- /Cell: Active Containers (Driver/, App/, Sensor/)
- /Bus: Active Interfaces (replaces /dev)
- /Data: Mutable Persistence (User/, Volume/)
- 'The Unix Lie' compatibility layer for legacy apps
VISION.MD UPDATE
----------------
• Added dedicated Rumpk section differentiating from Rumk
• Documented 4-layer architecture with ASCII diagram
• Listed key innovations: Adaptive I/O, Disruptor, SipHash, Ed25519
REPOSITORY STRUCTURE (core/rumpk/)
----------------------------------
core/rumpk/
├── boot/header.zig # Multiboot2/EFI entry
├── hal/abi.zig # L0→L1 ABI contract (struct HAL)
├── core/kernel.nim # kmain() entry point
├── core/ring.nim # Disruptor ring buffer
├── io/governor.nim # Adaptive War/Peace I/O
├── build.zig # Zig build orchestration
└── README.md # Feature index
DESIGN DECISIONS
----------------
• Hard ABI barrier: Zig exports C-compatible struct to Nim
• Language-agnostic: L1 can be swapped for Janus later
• No shared state: Fibers communicate via Channels only
• No JIT, No W^X violations: Code sections immutable
NEXT STEPS
----------
• Phase 1: Boot on QEMU (print 'Hello Rumpk')
• Phase 2: Nim runtime on bare metal
• Phase 3: Two fibers switching (Ping/Pong)
• Phase 4: NPL loading with signature verification
• Phase 5: VisionFive 2 hardware validation
This is the foundation for the 'OS Factory' vision.
Rumpk + Rumkv + NPL = Independent from Unix/Linux.
Tested: Directory structure validated
Status: ✅ SCAFFOLD COMPLETE
