iot.halowerk.com
Canonicalizes firmware hash, version, device model and minimum bootloader version, then produces a SHA-256 manifest digest and HMAC-SHA256 release tag using caller-supplied ephemeral key material. This is a symmetric integrity tag, not a vendor PKI signature or code-signing service.
