facet-rs

Guidelines for using facet crates (facet-json, facet-toml, figue) instead of serde-based alternatives for consistent dogfooding

Orientation to facet-format JIT deserialization (tiering, fallbacks, key types/entry points) and where to look when changing or debugging JIT code

Debug crashes, segfaults, and memory errors using valgrind integration with nextest through pre-configured profiles

Systematic workflow for debugging by reproducing bugs with real data, reducing test cases to minimal examples, and adding regression tests
