Méthode — Concentration des promesses

Bands describe how many products occupy a buyer × promised-outcome territory: crowded and proven (≥4 products, proof ≥50%), crowded and unproven (≥4, proof ≤49%), contested (2–3), sparse (1), and vacant (0). Robust mappings are explicit vendor claims or strong inference.

Saturation is not demand, whitespace opportunity, or a product score.
