jetstream is a Bluesky service API — jss v1 decode, network.bsky.jetstream.* — not atproto; the same line Bluesky drew splitting @bsky/sdk from @atproto/api. the new repo takes ArchiveBackfill, the streamplace example, the archive smoke script, and the vendored decode-only libzstd (zat no longer links zstd at all). JetstreamClient (the v1 /subscribe wire) stays here, functional and deprecated-in-home, until its consumers migrate; the subscribeEvents v2 client lands in the new repo. none of the moved code ever shipped in a zat release — it ships as jetstream 0.1.0.
