 Both publication workflows use the `simstore-releases` concurrency group with a multiple-run queue. Stable drafts can be retried, while an already published stable release cannot have its assets overwritten by the publisher. A delayed build cannot replace a newer nightly. The nightly's package and metadata are uploaded before its version index.
 
-Release descriptions retain the Terminal installation command and the instruction against downloading the archive through a browser. The command uses the release's own tag, including stable tags. Nightly publishing refreshes the index in the same workflow; it does not depend on a second release event generated by `GITHUB_TOKEN`.

The command stays on one line, uses the release's own tag including stable tags, and removes the temporary archive after extraction. The description warns against downloading through a browser. Nightly publishing refreshes the index in the same workflow; it does not depend on a second release event generated by `GITHUB_TOKEN`.
 
 To create a stable release, choose the next version and tag the tested main commit:
