Crafter.Build's CI publishes a Flatpak and nothing else since 2026-10-02: the rolling `latest` release's `crafter-build-linux-x86_64-musl-v2.tar.gz` that build-package.sh fetched is gone (404 since 2026-10-03), so a push of a release would fail at `fetch crafter-build` and publish nothing. Install the Flatpak (`net.catcrafts.CrafterBuild//stable` from flatpak.catcrafts.net) in the job container and run it as crafter-build. bubblewrap inside the container needs a privileged runner, so the job runs on the `flatpak` label. The sysroot stays Alpine edge and gains llvm-runtimes, the package with the std module source of its own libc++ (libc++-dev ships none). make-sysroot.sh adds its list with --upgrade: run over a sysroot from before this change (libc++ 22.1.8, no std module source) a plain add installed llvm-runtimes 23.1.2 alone, and its std.cppm did not compile against the 22.1.8 headers (`'text_encoding' file not found`); with --upgrade libc++, libc++-dev and llvm-runtimes came out at 23.1.2 and it compiled. AGENTS.md §4.1, §4.3, §8.3 and §9.4 describe the route as it runs, and the README's Building section carries the install lines. Three comments in the files this touches said what is not so and are corrected: package.yml had fp6-img install the package by a pinned version and sha256 (it takes the newest in the registry), build-package.sh had fp6-img's image build run `make check` on the aarch64 binaries (it builds no imsd: no suite runs on them), and make-sysroot.sh's usage line lacked the --march without which the cross build fails on an x86 host. Tested: build-package.sh run end to end on this commit in a privileged alpine:edge container (podman) on the workstation.
