Distinct operative representation paths are explicitly linked for downstream retrieval, reasoning, or control.

How experience becomes memory

Each path is one memory component, traced from what is stored to how it is found again.

How memory changes (T2 operations)

  • Update · Optimization-based update

    Sequential optimization writes edits into LoRA adapters. For MemEIC, this specifically supports a fixed operational optimization objective of dual visual and textual evidence.
