DR090 pairs Rule 2 Case 2a Filled Red (=) (Continuing column row r >= 2 where reference cell (k-m, r) is occupied) with Analytical Modality (Depth Vector Verification): learners verify Reference column d_{k-m} >= r so both (k-m, r) and (k-m, r-1) are filled, master Rule 2 Case 2a Populated Reference Cell returning Red (=), and eliminate checking completed column totals instead of cell occupancy at rows r and r-1.
DR090 drill board (PPBBBPPPPBBPBBBBBBPPPBP): 9 Big Road columns, 20 Big Eye Boy, 17 Small Road, and 13 Cockroach Pig marks.
This bead is at Row 2. Column 2 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 2 stopped exactly one row above this bead.
This bead is at Row 2. Column 1 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 1 stopped exactly one row above this bead.
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.
Continuing column row r >= 2 where reference cell (k-m, r) is occupied
Rule 2 Case 2a Populated Reference Cell returning Red (=)
Reference column d_{k-m} >= r so both (k-m, r) and (k-m, r-1) are filled
Checking completed column totals instead of cell occupancy at rows r and r-1
Verify that the reference column is still occupied at current row r by computing the full column-depth vector [d_1, d_2, ..., d_k] across the shoe
Verification lab DR090 pairs Analytical Depth Audit with Rule 2 Case 2a Filled Red (=) so students test Continuing column row r >= 2 where reference cell (k-m, r) is occupied and answer: How does the depth vector [d_1..d_k] determine all three derived roads?
Scoreboard inspection DR090 (Rule 2 Case 2a Filled Red (=) · Analytical Depth Audit) shows: This bead is at Row 2. Column 2 has a bead at Row 2 too → red (=). Tracking 17 Small Road and 13 Cockroach Pig marks answers How does the depth vector [d_1..d_k] determine all three derived roads?
| DR090 Drill Dimension | Coordinate / Rule | GMU Modality Action |
|---|---|---|
| DR090 Matrix Coordinate | Continuing column row r >= 2 where reference cell (k-m, r) is occupied | Analytical Modality (Depth Vector Verification) |
| DR090 Rule & Depth | Rule 2 Case 2a Populated Reference Cell returning Red (=) | Reference column d_{k-m} >= r so both (k-m, r) and (k-m, r-1) are filled |
| DR090 Diagnostic Target | Checking completed column totals instead of cell occupancy at rows r and r-1 | Verify that the reference column is still occupied at current row r |
Second-lookback check DR090 states: This bead is at Row 2. Column 1 has a bead at Row 2 too → red (=). By computing the full column-depth vector [d_1, d_2, ..., d_k] across the shoe, learners master Rule 2 Case 2a Filled Red (=) and Reference column d_{k-m} >= r so both (k-m, r) and (k-m, r-1) are filled over 9 columns.
