File function
Demonstrates the importance of 18726 BC before the downstream +50 parallel-column dates branch through En-tarah-ana toward the terminal anchors 2906 BC and 2856 BC.
Highlights
- Establishes the pre-branching 18726 BC / Nangishlishma-start anchor with the hidden 670 + 50 = 720 grammar.
- Tests pre-branching relations such as 18726 − 2166 = 16560 and 27366 − 18726 = 8640.
- Distinguishes the Historical Lock 430 state from the Cosmic Lock 432 state.
Reading context
The active anchor is the pre-branching 18726 BC state, not the later visible En-tarah-ana +50 branch controlled by File_24.
