The workflow only ever uploaded to the GitHub release — the Gitea release for the same version (the plain, unsuffixed vX.Y.Z tag build-app.yml's Linux job creates, which already holds the .deb/.rpm/.AppImage) never got it, so it looked missing to anyone checking releases on Gitea instead of GitHub. New step mirrors build-app.yml's own Gitea upload step exactly: same get-or-create-by-tag, delete-existing-asset, upload-as-octet-stream shape, same REGISTRY_TOKEN secret. Verified the read side (release lookup, asset listing) against the real v0.4.16 release before writing this — resolves to the correct release id and correctly finds no existing asset yet.
