nix's bun loads through a glibc in the nix store, and bun build --compile copied that loader into bin/quak, so nix-collect-garbage could break the cron backup. The build moves into script/build-bin. On Linux it downloads bun 1.3.13's release archive for the machine from GitHub: x86-64 (baseline) or arm64, glibc or musl. It checks the archive's SHA-256 before running it, and compiles with that bun, so the binary loads through the system loader. macOS still runs bun through nix-shell. Model: opus-5-5
