# homeassistant.* discovery knobs use "//=" so they are only seeded when
# missing. retain is seeded via an explicit has() check rather than "//=",
# because jq treats a user-set "retain: false" as falsy and "//=" would wrongly
# flip it back to true; has() seeds the default only when the key is truly
