Scala CLI official documentation publish.computeVersion git:tag version computation tag prefix v
💡 Result:
Scala CLI’s official `publish` documentation says `publish.computeVersion` accepts `git:tag` (or `git`). With `git:tag`, it uses the latest stable Git tag: a tag on `HEAD` supplies the version; if the latest tag is earlier in history, Scala CLI increments it and adds `-SNAPSHOT`; with no tag, it uses `0.1.0-SNAPSHOT`. Only semantic-version tags are considered. ([scala-cli.virtuslab.org](https://scala-cli.virtuslab.org/docs/commands/publishing/publish/?utm_source=openai))
The docs’ example tag is **`v1.2.3`**, which yields version **`1.2.3`**—so the `v` prefix is accepted and stripped. ([scala-cli.virtuslab.org](https://scala-cli.virtuslab.org/docs/commands/publishing/publish/?utm_source=openai))
Set it with `//> using publish.computeVersion git:tag` or the `--compute-version git:tag` option. ([scala-cli.virtuslab.org](https://scala-cli.virtuslab.org/docs/commands/publishing/publish/?utm_source=openai))

Restrict both baseline candidates to version tags.
On a push to main, a tag such as v999 can pass the hyphen filter and sort ahead of a real release such as v1.2.3. The publishing workflow triggers for v* tags, but publish.computeVersion git:tag considers only semantic-version tags, so it will not publish version 999 from v999. Baseline resolution or the following artifact-path grep can then fail before the report is written.
The stable regex in the proposed fix does not constrain the fallback. Filter the tag list first so the fallback still selects a prerelease when no stable release exists, but cannot select a non-version tag.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
