写下来吧，这样的香气很容易被忘记。要我帮你记一笔吗？Write it down — scents like that fade so easily. Want me to jot a note?

还有咖啡店的白猫睡在窗台上，被太阳晒成一团毛糕。And the café's white cat asleep on the sill, melted into sunlight.

读完了《夜航船》。Just finished Zhang Dai's Night Boat.

03 · 合理否认性Plausible deniability

两把锁，一个
秘密的保险库。 Two keys, one
private vault.

输入错误密码，喃喃会打开一个完全独立、看起来无害的日记 —— 有自己的内容和气氛。真实的那个，没人能证明它存在。 The wrong password opens a harmless, fully-populated diary of its own. Your real one stays invisible — provably so.

私密空间用 AES-256-GCM 加密，主密钥由密码 + 恢复码双重保护。两把独立的锁，守护同一个保险库。 The private space uses AES-256-GCM with a master key guarded by your password and a recovery code. Two independent keys on the same vault.
