The PLAN.md CI contract in remote mode. client/http_client.sx is the temporary in-repo HTTP client shim over std.socket (connect(2) via libc FFI), targeting http://<ipv4-or-localhost>:<port> — DNS and TLS are loud v0 boundaries (https:// is refused; the deployment story terminates TLS at a reverse proxy). publish/remote.sx drives the same manifest front half as local publish, uploads each artifact through POST /api/upload (verifying a manifest-declared sha256 against the server-computed digest), then publishes via POST /api/apps/<slug>/releases. The 200 response is parsed back into a PublishOutcome so --json/human rendering reuse the local paths; non-2xx responses pass the server's JSON error code through report_failure. ci publish takes exactly one of --local-store or --server (+--token); anything else is a usage error. make test 18/18 (new: remote_publish.sx pinned acceptance against a live distd).
