 - **First publish auto-creates** the package name. No separate registration.
 - **Versions are immutable.** Re-publishing the same `(name, version)` returns **409 Conflict**. Bump the version.
 - **Flat global namespace** — no scopes. Pick a distinctive name (we use `epson-print-service`).
-- **CLI artifacts:** only `linux-arm64` and `win-x64` today. On `linux-x64` CI, run under qemu (`--platform linux/arm64`) — the CLI is just packer + uploader so emulation is fine.
+- **CLI artifacts** ship for `linux-x64`, `linux-arm64`, `linux-arm`, and `win-x64` (as of CLI 1.3.1). Pick the RID that matches the host; no qemu required.
 - **`insin pack` output is one dir UP** (`../packages/`), not `./`. Look there if the `.pkg` seems missing.
 - If both `INSIN_ADMIN_TOKEN` and `INSIN_TOKEN` are set, `publish` reads `INSIN_TOKEN` first (service token wins).
