Module host_facts 

Per-host OS primitives (boot_id, pending_generation); cfg-gated re-export.

Modules

linux 🔒

Linux/NixOS impl: /proc + /run/booted-system.

Constants

CURRENT_SYSTEM

/run/current-system symlink target’s basename = the activated system’s closure hash. The agent doesn’t trust CP’s “what closure did you activate” reads; it always reports what the OS says.

Functions

boot_id

closure_hash_from_path 🔒

FOOTGUN: returns full basename, NOT 32-char prefix — byte-equality required across CP / CI / agent.

current_closure_hash

current_generation_ref

channel_ref is None until the projection correlates it.

pending_generation
