Querying Play with the new service account showed production live on 1.0.5+7 while the committed pubspec said 1.0.5+6 -- a build was uploaded straight from a working copy without the bump ever being committed, so git understated the real version. Version code 7 was therefore already taken and the 1.1.0+7 artifacts would have been rejected on upload. Other tracks are well behind (alpha 4, internal 2), so 8 clears everything live. Document the pre-bump check in RELEASING.md so the next release starts from what the store reports rather than from pubspec.yaml. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
