Reconstructs the actual journey each visitor took from the per-session journey-stage labels Visitor Intelligence records (vi2_unified), derives the IDEAL stage order straight from the data — stages ordered by where they typically occur, no invented vocabulary — and runs gap analysis: a stage funnel with drop-offs, the single biggest leak, and per-visitor how-far-they-got versus where-they-dropped, including out-of-order deviations. A transparent, data-driven model (not an LLM). Reads existing data — no extra tracking, cookieless. Feeds the Journey panel of the Visitor Intelligence hub.
