The entry comes from upstream's AppImage rather than a hand-written one, because that is what carries the t3code:// scheme handlers, and it arrives named "T3 Code (Alpha)" from electron-builder's productName. That name is stale: the app's own code calls it `legacyUserDataDirName` and has already moved its data to ~/.config/t3code, so the launcher was advertising an identity upstream has moved off.
Rewrite Name= alongside the Exec= rewrite already there. The scheme handlers, the MimeType line and the rest of upstream's entry are untouched.
pkgrel goes to 2 because 0.0.33-1 is already published, and a packaging-only change reaches an installed machine only through a new release.
