$ jc-rs /proc/devices

A real pair

From the reference corpus (linux-proc/devices.json). The left pane is the input the fixture ships; the right pane is the corpus's expected JSON. CI compares jc-rs with it field by field under the published differential. Hover a value to see where it came from.

Magic syntax

jc-rs /proc/devicesjc-rs reads this kernel-interface file directly and dispatches it through the matching /proc parser.

Source: crates/jc-rs-parsers/src/proc/proc_devices.rs. jc-rs targets the schemas defined by the original Python tool. Fixture coverage above is the measured evidence for this parser; test the inputs your pipeline depends on. Compare
