CortexFS
A small Linux filesystem ABI for agent runtimes: model, agent, tool, session, policy, and shared files without provider or workflow internals in the root namespace.

shared/Frozen root ABI
The root contains stable object classes only. Provider, database, MCP, skill, and workflow details stay out of `/ctx`.
Unix-shaped objects
Executable files do work, `.sock` files stream stateful JSONL, and `.d/` directories hold small control files.
Thin clients
`ctx` and `agent.sh` are small clients over the ABI. Agent orchestration remains policy-bound runtime behavior.
