# 2. Config-key coverage used to be checked here with `sed`, which only saw
#    fields written as `key: Some(...)` — so `units`, `refresh_secs`,
#    `graph_style`, `agp_days`, `sites` and the whole `minimap` table were
#    never checked, and the gate reported success while covering about half of
#    what it claimed. It is now a Rust test that serializes a Config and
#    asserts every emitted key appears in config.example.toml, which is
#    exhaustive by construction: see `every_persisted_key_is_documented`.
