UnverifiedCode obfuscation destroys the readable structure of code by renaming symbols, inserting useless instructions, control flow flattening, etc.; anti-reverse engineering includes packing, anti-debugging, integrity checks, etc.74% similarUnverified语义漂移（semantic drift）指模型在缺乏明确语义锚点的情况下逐渐偏离有意义的内容生成轨道，最终输出与查询意图脱节的文本73% similarUnverifiedThe cAST paper (Carnegie Mellon University and Augment Code) found that line-based chunking heuristics often break semantic structure, splitting functions apart or merging unrelated code together.71% similarUnverifiedThe noexcept operator and the noexcept specifier are two distinct language mechanisms; the operator returns a compile-time boolean indicating whether an expression is declared as non-throwing, without executing the function body.71% similarUnverified代码的语义更多体现在结构关系而非字面文本，一个函数改动的影响范围必须沿调用图遍历而非仅靠语义相似度捕获70% similar
