Tested a real encrypted room file: it carries only the PBKDF2-wrapped master (no master key, no plaintext password), so the only path is offline guessing. Measured throughput with the project's own unlock() against a throwaway weak-PIN room (~20 guesses/sec single thread) and tabulated crack times — weak passwords fall fast, the generated ~99-bit password is infeasible. Dated and attributed to the model that ran it. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PCUwNSXQdqfDSugmFo4qmM

概要
把一次口令提取测试的报告写进 README。测试对象是一个真实的加密房间文件。
结论
unlock()，对一个自建的弱口令（4 位 PIN）房间完整爆破计时，单核约 20 次/秒；据此给出破解时间表——弱口令秒破至几天，「随机生成口令」（约 99 位熵）约 5×10²⁰ 年，不可行。报告带日期和执行模型版本（Claude Opus 4.8，
claude-opus-4-8），并与 README 既有的口令强度表对应。范围与安全
