The one giant `runtime` module (with a `system.zig` that was itself a dumping ground of unrelated syscalls) is split into directly-importable, flat concern modules under library/kernel/: system-call ipc memory process thread time logging file-system service start (+ the device/service clients: device, device-manager, block, display, input) system.zig is dissolved — its functions moved to their concern home (mmap -> memory, spawn/kill/exit -> process, sleep/clock -> time, write/klog -> logging, fs* -> file-system). `memory` merges heap+dma+shared-memory behind one flat API (memory.allocator/dmaAlloc/sharedCreate/mmap), keeping heap's state and malloc export single. The memory<->thread dependency cycle (heap needs Thread.Mutex, thread needs mmap) is broken by having thread allocate its own stack via the raw mmap syscall, so the module graph is a DAG. This is the atomic step: all 42 internal cross-imports flip from relative to module imports at once. `runtime.zig` and `system.zig` become thin re-export SHIMS so the ~38 consumers keep compiling on `runtime.*` untouched; they migrate to direct imports in C2, after which the shims are deleted (C5). zig build + zig build test green; 14 QEMU cases pass (smoke, process, process-kill, thread-spawn/join, logger, vfs, fat-mount, display-native, usb-storage, virtio-gpu, device-manager, input, power-button).

//! system.zig — a **compatibility shim**, not the real home of anything anymore.

//!
|
|
//! The runtime's syscall surface used to be dumped here in one file. It has been split by
|
|
//! concern into `time` / `logging` / `process` / `file-system` / `memory`. This re-exports
|
|
//! the old flat `system.*` names from those homes so consumers that still write
|
|
//! `runtime.system.write` (etc.) keep compiling until they migrate to the concern modules.
|
|
//! Deleted once nothing references `runtime.system` (reorg step C5).
