+Releases are prepared through the `Prepare Release` workflow. The workflow creates a release and uploads prebuilt `vociferate` binaries for:
 
-- `darwin/amd64`
-- `darwin/arm64`
 - `linux/amd64`
 - `linux/arm64`
-- `windows/amd64`
-- `windows/arm64`
 
 It also uploads `checksums.txt` for integrity verification.
 If a release already exists for the same tag, the workflow updates its release notes and replaces matching asset filenames so reruns stay in sync.

 ### Changed
 
+- Release preparation now runs directly in the release workflow; the repository-local helper script and just recipe were removed.
+- Release artifacts are now limited to `linux/amd64` and `linux/arm64` binaries plus `checksums.txt`.
 - The CLI entrypoint, internal package paths, build outputs, and automation references now use the `vociferate` name instead of the earlier `releaseprep` naming.
 - The release workflow and composite action now treat a provided `version` as an override and otherwise fall back to the recommended next version automatically.
 - Release creation is now idempotent: existing releases for the same tag are updated in place instead of recreated.
