Crate os_service_fabric 

os_service_fabric is a dependency-free, no_std-first framework for modeling and orchestrating operating system services.

It defines:

• explicit service lifecycles (state module)
• static, allocation-free dependency graphs (graph module)
• health reporting (health module)
• recovery policies (policy module)
• a deterministic runtime that drives services (runtime module)

The crate does not perform I/O, allocation, or logging on its own. It is intended to be integrated into kernels or bare-metal frameworks that provide these capabilities externally.
