YggdraSIM
Drive real eUICCs and SIM cards, run OTA and SCP11 relay sessions, simulate a UICC backend, and lint SAIP profile packages — every secure-element workflow from one Python operator shell.
Like Yggdrasil binding the Nine Realms, it connects the card, relay, OTA, profile-package, and HIL layers no other open toolkit spans together.
