Trapdoor.si

Trapdoor.si — a cryptographic and AI-security term of art. Trapdoor functions are foundational to cryptography; "trapdoored models" name a live AI-security concern — hidden backdoors and sleeper behaviors planted in models. A rare one-word domain for security, cryptography, red-teaming, or model-integrity work. Sharp, category-native, and technically credible. .si reads as SI, superintelligence.
