The bucket has two ends in two crates: a hive writes its own key, the controller reads every key. `swarm-controller` declared the name as a private const with a doc comment arguing that "reader and writer must name the same bucket" — an argument the writer, in another crate, could not obey. The name is the mild half. Both ends do get-or-create, because either may come up first on a fresh swarm and neither can assume the other has run. Two `Config`s that drift means whichever end created the bucket wins and the other's `get_key_value` succeeds against a bucket it did not ask for: no error, no log, just a retention policy nobody chose. Sharing the constructor gives that race one outcome. Behind a default-off `kv` feature, so the crate's other consumer — the auth-callout responder, which speaks the connect and nothing else — still pulls neither `jetstream` nor `kv`. That was the actual reason the feature was excluded when this crate was extracted; the flag preserves it. The surface is deliberately narrow: one bucket's name and creation config, not a general KV facade.

# OFF by default, and that default is the point: the auth-callout responder

# one bucket two crates open from opposite ends (`src/status.rs`), not a

|

# to live in one of them, and neither end of that bucket is senior to the
