   1. Fetch the artifact and its sidecars

      Every release ships a bare-hash checksum and a detached GPG signature over that checksum.

      curl -O https://releases.aembit.io/mcp_gateway/1.28.4136/linux/amd64/aembit_mcp_gateway_linux_amd64_1.28.4136.tar.gz
      curl -O https://releases.aembit.io/mcp_gateway/1.28.4136/linux/amd64/aembit_mcp_gateway_linux_amd64_1.28.4136.tar.gz.sha256
      curl -O https://releases.aembit.io/mcp_gateway/1.28.4136/linux/amd64/aembit_mcp_gateway_linux_amd64_1.28.4136.tar.gz.sha256.sig

   2. Import Aembit’s signing key

      One time per machine.

      curl -sS https://keybase.io/aembit/pgp_keys.asc | gpg --import

   3. Check the signature on the checksum

      This proves the checksum came from Aembit and was not altered in transit.

      gpg --verify aembit_mcp_gateway_linux_amd64_1.28.4136.tar.gz.sha256.sig aembit_mcp_gateway_linux_amd64_1.28.4136.tar.gz.sha256
      gpg: Signature made …
      gpg: Good signature from "Aembit, Inc. <keybase@aembit.io>" [unknown]
      Primary key fingerprint: EA3D 8D2F DAC6 BD81 3716  3D00 D655 E647 29BC 67D7

   4. Compare the artifact against the checksum

      These files hold a bare hash with no filename, so shasum -c needs the two-column form rebuilt first.

      echo "$(cat aembit_mcp_gateway_linux_amd64_1.28.4136.tar.gz.sha256)  aembit_mcp_gateway_linux_amd64_1.28.4136.tar.gz" | shasum -a 256 -c -
      aembit_mcp_gateway_linux_amd64_1.28.4136.tar.gz: OK
