A real pair

From the reference corpus (centos-7.7/vmstat.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 vmstatjc-rs runs the command itself and parses what it prints. Recognised for: `vmstat`

Source: crates/jc-rs-parsers/src/system/vmstat.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
