The five fluctuations are: valid cognition, error, imagination, sleep, and memory.

These represent the Five Standard Protocols of the mind-field. Every packet of data that passes through awareness can be categorized into one of these five protocols. In Mind OS, understanding them is equivalent to understanding the system’s Activity Monitor.

Pramāṇa (Valid Cognition): Direct perception, logical inference, or reliable testimony.

Viparyaya (Error): False data generated by misinterpretation of the source.

Vikalpa (Imagination): Synthesized data without a corresponding external referent.

Nidrā (Sleep): A registered state of absence. Not the absence of data, but the cognition of absence itself.

Smṛti (Memory): Retrieval of previously stored data from long-term storage.

五大协议

五种波动分别是：正知、谬误、幻想、睡眠与记忆。

这些代表了心智场的五大标准协议。每一条进入意识的数据流，都可以被归类到这五种协议之中。在 Mind OS 中，理解这些等同于理解系统的“活动监视器”。

Pramāṇa（正知）：直接感知、逻辑推导或可靠见证所得的数据。

Viparyaya（谬误）：由对信息源误读而生成的错误数据。

Vikalpa（幻想）：缺乏外部对应物的合成数据（纯概念）。

Nidrā（睡眠）：一种被记录的“缺失状态”，并非没有数据，而是对“缺失可识别对象”的认知。

Smṛti（记忆）：从长期存储中调取既有数据的过程。
