## Analysis tables (filled by A6.P2)

### Table 1 — Per-site push-back delta

*Placeholder — filled by A6.P2 analysis. Rows = (site × scenario) cross-product.
Delta computed as `‖output_center − input_center‖` per call. Bug candidate
threshold: ratio > 3× retail.*

| Site | Scenario | Retail mean delta (mm) | Retail p99 (mm) | acdream mean (mm) | acdream p99 (mm) | Ratio |
|---|---|---|---|---|---|---|

### Table 2 — Path-frequency diff

*Placeholder — filled by A6.P2 analysis. Paths labeled 1-7 per the
find_collisions dispatcher.*

| Scenario | Path | Retail count | acdream count | Diff % |
|---|---|---|---|---|

### Table 3 — ContactPlane lifecycle diff

*Placeholder — filled by A6.P2 analysis.*

| Scenario | Retail CP writes/sec | acdream CP writes/sec | Retail CP-restore-from-LKCP/sec | acdream CP-restore/sec |
|---|---|---|---|---|

### Table 4 — Sub-step state mutations

*Placeholder — filled by A6.P2 analysis. Fields: cell_array_valid,
hits_interior_cell, walk_interp, walkable, collide.*

| Scenario | Field | Retail mutations/sec | acdream mutations/sec |
|---|---|---|---|

## Per-scenario narrative (filled by A6.P2)

### Scenario 1 — Inn doorway entry

*Placeholder.*

### Scenario 2 — Inn stairs ascent

*Placeholder.*

*(etc. — 3 through 9)*
