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

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
