DR258 pairs 3-2-3-2 Depth Alternation (Big Road depths [3, 2, 3, 2] comparing m=1 vs m=2 lookbacks) with Question-Driven Modality (Self-Test Triage): learners verify For m=1, d_3=3 != d_2=2 (Blue); for m=2, d_3=3 == d_1=3 (Red), master Lookback Divergence: Big Eye Boy Blue vs Small Road Red, and eliminate assuming all three derived roads must show the same color on a hand.
DR258 drill board (PPBBPPPPBBPBBBPBTBPPBBP): 11 Big Road columns, 19 Big Eye Boy, 17 Small Road, and 13 Cockroach Pig marks.
This bead is at Row 3. Column 2 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 2 stopped exactly one row above this bead.
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.
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.
Big Road depths [3, 2, 3, 2] comparing m=1 vs m=2 lookbacks
Lookback Divergence: Big Eye Boy Blue vs Small Road Red
For m=1, d_3=3 != d_2=2 (Blue); for m=2, d_3=3 == d_1=3 (Red)
Assuming all three derived roads must show the same color on a hand
Verify why Small Road (m=2) marks red while Big Eye Boy (m=1) marks blue by diagnosing off-by-one column lookbacks and Case 2b vs Case 2c mixups
When practicing 3-2-3-2 Depth Alternation in DR258, Question-Driven Error Audit focuses on Lookback Divergence: Big Eye Boy Blue vs Small Road Red so readers verify For m=1, d_3=3 != d_2=2 (Blue); for m=2, d_3=3 == d_1=3 (Red) across 11 streaks of PPBBPPPPB-BPBBBPBTB.
Engine trace DR258 for 3-2-3-2 Depth Alternation verifies: This bead is at Row 3. Column 2 stopped at Row 2, one row above → blue (≠). Across 17 Small Road dots and 13 Cockroach Pig slashes, diagnosing off-by-one column lookbacks and Case 2b vs Case 2c mixups anchors every lookback.
