3# generate-release-assets.sh — build leveva for x86_64 + aarch64 and emit
4# .deb and .rpm packages for each architecture.
5#
6# Cross-compilation is handled by cargo-zigbuild (zig as the linker/sysroot),
7# so no per-arch C toolchain is required. Both targets are static musl builds.
8# Packaging is pure-Rust: cargo-deb and cargo-generate-rpm read the
9# [package.metadata.deb] / [package.metadata.generate-rpm] tables in
10# leveva/Cargo.toml. Passing --target to each rewrites the `target/release/`
11# asset prefix to `target/<triple>/release/`, so they pick up the cross binary.
12#
13# The architecture set is the one leveva ships images for — the platforms in
14# docker-bake.hcl / docker/Dockerfile.leveva (amd64, arm64, ppc64le, ppc64,
15# riscv64), mapped to their musl triples below.
16#
17# Outputs (relative to the workspace root):
18# target/<triple>/debian/leveva_<ver>_<arch>.deb
19# target/<triple>/generate-rpm/leveva-<ver>-1.<arch>.rpm
20# and a copy of every artifact collected under var/dist/leveva-<ver>/, where
21# <ver> is leveva's package version from leveva/Cargo.toml.
