Done

Shipped · runs on QEMU / hardware

AArch64 exception model + MMU virtual memory (EL0–EL3)
SMP preemptive scheduler per-CPU + load balancing, split scontext/xcontext

Four boot platforms QemuVirt · Pi3B · Pi4B · CM4

In Progress

Tracked in the repo TODO

Process-exit resource release completing capability, memory and IPC resource reclamation when a process dies
Service startup dependencies adding deps declarations to service configs so init builds the launch order from the dependency graph instead of a fixed sequence

Ongoing polish

Performance tracing extending perf / perfmgr coverage across subsystems
Documentation keeping design and interface docs in sync with the implementation

Exploring

Stubbed or scoped directions

Trustee / TEE trusted execution environment (sys/trustee/ is currently a stub)
Fastcall high-performance kernel-inline call path (currently a stub)
More scheduler classes policy plugins beyond CFS on the module system
Deeper AI agent framework tighter agentmgr integration with system services

Progress lives in the repository.
