DR242 pairs Double-Jump 2x2 Symmetry (BB-PP-BB-PP columns of depth 2 across Big Road cols 1-4) with Visual Modality (Color & Shape Discrimination): learners verify Row 1 marks red via d_{k-1}=2; Row 2 marks red via occupied (k-m,2), master Rule 1 Depth-2 Equality Paired with Rule 2 Case 2a Filled Cell, and eliminate thinking row 2 of a 2x2 pattern turns blue before the column switches.
DR242 drill board (PPBBPPPBBPBBBPPBTBPPBBP): 11 Big Road columns, 19 Big Eye Boy, 17 Small Road, and 14 Cockroach Pig marks.
This bead is at Row 2. Column 3 has a bead at Row 2 too → red (=).
Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 3 stopped exactly one row above this bead.
Column 3 has 3 beads. Column 1 has 2 beads. Different depth → blue (≠).
Common table reading watchout: Comparing the wrong columns. Compare Column 3, the one that just finished, with Column 1.
This bead is at Row 2. Column 3 has a bead at Row 2 too → red (=).
Common table reading watchout: Thinking "no bead at this row" means blue. It is blue only when Column 3 stopped exactly one row above this bead.
BB-PP-BB-PP columns of depth 2 across Big Road cols 1-4
Rule 1 Depth-2 Equality Paired with Rule 2 Case 2a Filled Cell
Row 1 marks red via d_{k-1}=2; Row 2 marks red via occupied (k-m,2)
Thinking Row 2 of a 2x2 pattern turns blue before the column switches
Trace both Row 1 (Rule 1) and Row 2 (Rule 2 Case 2a) in a 2x2 shoe by distinguishing hollow circles, solid dots, and slashes without color bias
When practicing Double-Jump 2x2 Symmetry in DR242, Visual Symmetry Check focuses on Rule 1 Depth-2 Equality Paired with Rule 2 Case 2a Filled Cell so readers verify Row 1 marks red via d_{k-1}=2; Row 2 marks red via occupied (k-m,2) across 11 streaks of PPBBPPPBB-PBBBPPBTB.
Engine trace DR242 for Double-Jump 2x2 Symmetry verifies: This bead is at Row 2. Column 3 has a bead at Row 2 too → red (=). Across 17 Small Road dots and 14 Cockroach Pig slashes, distinguishing hollow circles, solid dots, and slashes without color bias anchors every lookback.

| DR242 Matrix Coordinate | BB-PP-BB-PP columns of depth 2 across Big Road cols 1-4 | Visual Modality (Color & Shape Discrimination) |
| DR242 Rule & Depth | Rule 1 Depth-2 Equality Paired with Rule 2 Case 2a Filled Cell | Row 1 marks red via d_{k-1}=2; Row 2 marks red via occupied (k-m,2) |
| DR242 Diagnostic Target | Thinking Row 2 of a 2x2 pattern turns blue before the column switches | Trace both Row 1 (Rule 1) and Row 2 (Rule 2 Case 2a) in a 2x2 shoe |
Verification step 2 in DR242 reads: Column 3 has 3 beads. Column 1 has 2 beads. Different depth → blue (≠). Through Visual Symmetry Check, Double-Jump 2x2 Symmetry achieves trace both row 1 (rule 1) and row 2 (rule 2 case 2a) in a 2x2 shoe over 11 streaks.
