+## Script release versions
+
+Every new script upload needs a release version in `MAJOR.MINOR.PATCH` form,
+for example `1.2.0`. Enter a version for each file in the upload drawer, script
+page, or beta replacement dialog. Versions belong to individual scripts; a batch
+can contain different versions.
+
+To fill empty fields automatically, choose `versions.json` from the same source
+checkout as your scripts. Cherry matches exact, case-sensitive filenames (such as
+`tws_t5_hud.gsc`) and leaves entered values intact. Review the values before
+uploading. A manifest identifies source releases; it does not verify file contents.
+
+Changing a script requires a new release version. Reuploading identical bytes with
+the same version reuses the saved release; different bytes with that version are
+rejected. Older release versions can be imported. Cherry keeps its upload number
+separately, displaying labels such as `1.2.0 (upload 7)`.
+
+Historical scripts without a release label display `Unversioned (upload N)` and
+remain available for testing, promotion, and rollback. Cherry does not infer old
+versions from today's manifest or rewrite historical records. Uploading the same
+bytes with an explicit version creates a separate labeled record when needed.
+Plugins retain optional publisher tags; configurations retain automatic upload
+numbers.
+
+API clients must include multipart `releaseVersion` when creating a script with
+`POST /api/scripts` or uploading with `POST /api/scripts/:id/versions`. Missing or
+invalid versions return HTTP 400; conflicting contents return HTTP 409. The
+version upload response reports `reused: true` for an existing identical release.
