- scripts/ota_keygen.sh: ECDSA P-256 key pair; the private key goes to ~/.config/roro9stack/ (0600), the public key to keys/ and src/platform/ota_public_key.h; .gitignore refuses *key.pem - scripts/make_ota.py: wraps firmware.bin into a signed .ota (openssl) - scripts/ota_push.py: sends it over TCP 3232, prints the device's answer - scripts/flash.sh --ota <host>: build, sign, push Checked: a generated .ota has the documented layout and its signature verifies with openssl against the committed public key.
