CS Architecture Builder

Generate an audit-ready ISO/SAE 21434 Cybersecurity Architecture workbook from a CS Concept xlsx and a CS architecture JSON. Produces 12-tab xlsx with CSR catalog, cryptographic inventory, key management, secure boot chain, secure communication, access control, CSR-to-element allocation matrix, and defense-in-depth layers. Essential for bridging CSR allocations from system cybersecurity requirements into concrete security controls, cryptographic key plans, and HSM/secure element architectures. Use whenever the user mentions cybersecurity architecture, security controls, key management, secure boot, or cryptographic design in an automotive cybersecurity context. Always use…
