Phase 72.5.2.3 adds @v2/session-funnel-analysis, the operational funnel surface for the new-player path from tutorial through first purchase. The policy is v2-session-funnel-analysis-v1.

buildV2SessionFunnelAnalysisSurface composes @iris/analytics-funnel to analyze the ordered tutorial, first mission, open world, and first purchase steps. It emits step entrants, conversion rates, drop-off rates, drop-off reason counts, and chart-ready bars for dashboard rendering.

The service consumes hashed account identifiers (accountIdHash) and session IDs. Output surfaces expose aggregate funnel and drop-off data only; raw account IDs are not accepted or emitted.

Operator Surface#

Rendered UI should put the funnel chart and step table first: tutorial, first mission, open world, and first purchase should remain visible as the canonical sequence. Drop-off rate, conversion rate from previous step, and drop-off reason breakdowns should be scannable without hiding the trend behind decorative visuals.

Segment controls can switch acquisition cohort, platform, and time window when those filters are available. Keep the first screen focused on the new-player flow and the highest drop-off step.
