Device: - Extract monolithic functions into focused helpers - Leverage ssl_cert library functions for validation/operations - Add comprehensive documentation and fix pattern matching warnings - Organize with public API at top, internal helpers at bottom HTTP Server: - Reorganize functions by functionality with clear sections - Add module constants for hardcoded values (ports, timeouts, paths) - Eliminate duplicate code with shared utility functions - Add type specifications and comprehensive documentation - Standardize error handling and improve function naming Key benefits: - Better maintainability through focused, single-purpose functions - Increased code reuse by leveraging existing libraries - Production-ready code following Erlang best practices ---

Key changes: - C NIF handles hardware (ioctl) and crypto (OpenSSL) - Erlang handles JSON serialization, certificate parsing, data transformation - Returns binary report structure (1184 bytes) instead of JSON - Auto-converts between JSON/binary and PEM/DER formats - OpenSSL 3.0 compatible (uses EVP API, no deprecated functions) - Comprehensive error handling with error codes - Eliminated buffer overflow risks Breaking changes: - generate_attestation_report/2 returns binary instead of JSON Use report_binary_to_json/1 to convert to JSON - verify_signature/3 accepts binary report (auto-converts from JSON) Files: - native/dev_snp_nif/*.c: C NIF implementation -
