The newest go-json-experiment/json, which wails/v3's application package imports, declares go 1.26, so taking it raises our go directive with it. Every other place that names a Go version moves in the same commit: GO_VERSION in ci, desktop-assets and android-apk, the Arch makedepends, and CONTRIBUTING's table. index-artifact's container image moves too, and it is the one that matters most. The official golang images set GOTOOLCHAIN=local, so a golang:1.25 container refuses a go 1.26 module outright rather than fetching a newer toolchain, and that job owns the ~205 GB checkpoint.
