Erik 260c60f8f5 docs(research): A6.P1 — capture directory structure + findings stub

Creates the 9 per-scenario capture directories (gitkeep stubs) and
the findings doc stub at docs/research/2026-05-21-a6-cdb-capture-findings.md.
A6.P1 fills the capture log slots (Task 15, user-driven); A6.P2
fills the analysis tables and findings section.

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
