DR121 pairs Tie Slash Indexing Check (Big Road active cell receiving green Tie slash vs Bead Plate cell) with Visual Modality (Spatial Matrix Inspection): learners verify Column index k and depth d_k remain unchanged on a resolved Tie hand, master Tie Non-Advancement Rule on Big Road and Derived Roads, and eliminate adding a new big road circle or derived road mark when a tie occurs.
DR121 drill board (BBPPBBBPPBPPPBBPTPBBPP): 10 Big Road columns, 18 Big Eye Boy, 16 Small Road, and 13 Cockroach Pig marks.
Column 3 has 3 beads. Column 2 has 2 beads. Different depth → blue (≠).
Common table reading watchout: Comparing the wrong columns. Compare Column 3, the one that just finished, with Column 2.
This bead is at Row 3. Column 1 stopped at Row 2, one row above → blue (≠).
Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 1 stopped exactly one row above this bead.
Column 5 has 1 bead. Column 2 has 2 beads. Different depth → blue (≠).
Common table reading watchout: Comparing the wrong columns. Compare Column 5, the one that just finished, with Column 2.
Big Road active cell receiving green Tie slash vs Bead Plate cell
Tie Non-Advancement Rule on Big Road and Derived Roads
Column index k and depth d_k remain unchanged on a resolved Tie hand
Adding a new Big Road circle or derived road mark when a Tie occurs
Confirm that Ties advance the Bead Plate while leaving derived roads paused by sight-tracing column heights and reference cells across the 6-row grid
Through sight-tracing column heights and reference cells across the 6-row grid in DR121, Tie Slash Indexing Check demonstrates Column index k and depth d_k remain unchanged on a resolved Tie hand across 10 Big Road columns and 18 derived comparisons.
During DR121 practice (GMU VISUAL MODALITY · GRID TRACE), Column 3 has 3 beads. Column 2 has 2 beads. Different depth → blue (≠). Pairing 16 Small Road and 13 Cockroach Pig entries with Big Road active cell receiving green Tie slash vs Bead Plate cell resolves Which exact reference cell or column depth governs the active coordinate?
| DR121 Drill Dimension | Coordinate / Rule | GMU Modality Action |
|---|---|---|
| DR121 Matrix Coordinate | Big Road active cell receiving green Tie slash vs Bead Plate cell | Visual Modality (Spatial Matrix Inspection) |
| DR121 Rule & Depth | Tie Non-Advancement Rule on Big Road and Derived Roads | Column index k and depth d_k remain unchanged on a resolved Tie hand |
| DR121 Diagnostic Target | Adding a new Big Road circle or derived road mark when a Tie occurs | Confirm that Ties advance the Bead Plate while leaving derived roads paused |
Further along the DR121 scoreboard (10 columns), This bead is at Row 3. Column 1 stopped at Row 2, one row above → blue (≠). Answering "Which exact reference cell or column depth governs the active coordinate?" cements Tie Non-Advancement Rule on Big Road and Derived Roads.
