BUILD NOTE · v10 vs the elevation spec
This build re-lays the board into six elevation tiers per the spec (redline items 1–9 all accepted as called), using the real v9 base (41 nodes, matching the spec's own count) as source. The first-uploaded file was a later, partial cut (v12, 36 nodes) missing 7 of those — U37, U38, U39, U40, U41, U42, U43 — and had already folded Retail Media & Search and Reach & Delivery into a single Paid Media node; the actual v9 file supplied the real content for all of it, so nothing here is invented or stubbed.
U43 Cost Position is absorbed into C07 Economics per the spec's own instruction, its content (gross margin, WTP, the Section 122 / Lee Kum Kee cost-position risk) carried in whole. Net: 47 nodes, 102 edges — matching the spec's own math exactly.
