DR248 pairs Double-Jump 2x2 Symmetry (BB-PP-BB-PP columns of depth 2 across Big Road cols 1-4) with Question-Driven Modality (Self-Test Triage): 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.
DR248 drill board (PPBBPPPPBBPBBBPBPTBBPBBBP): 13 Big Road columns, 21 Big Eye Boy, 19 Small Road, and 15 Cockroach Pig marks.
Column 3 has 4 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.
Column 3 has 4 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.
Column 4 has 2 beads. Column 1 has 2 beads. Same depth → red (=).

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 diagnosing off-by-one column lookbacks and Case 2b vs Case 2c mixups
Scoreboard workout DR248 applies Question-Driven Error Audit to Double-Jump 2x2 Symmetry: learners inspect Row 1 marks red via d_{k-1}=2; Row 2 marks red via occupied (k-m,2) across 13 columns of PPBBPPPPBBPBBBPBPT and correct thinking row 2 of a 2x2 pattern turns blue before the column switches.
Step-by-step trace DR248 for Double-Jump 2x2 Symmetry states: Column 3 has 4 beads. Column 2 has 2 beads. Different depth → blue (≠). With 19 Small Road and 15 Cockroach Pig marks visible, Question-Driven Error Audit fulfills trace both row 1 (rule 1) and row 2 (rule 2 case 2a) in a 2x2 shoe.
