## Notes

- Binaries are served from `https://downloads.claude.ai/claude-code-releases/`
as a single executable per platform (no archive). Linux uses the static
`musl` build so it runs on both glibc and musl hosts.
as a single executable per platform (no archive). Linux uses the glibc build:
the upstream `musl` variant is dynamically linked against the musl loader (not
static), so it fails on glibc hosts such as standard CI runners.
- Upstream publishes checksums only inside a per-version `manifest.json`, which
the TOML plugin format cannot parse, so installs are not checksum-verified.
