+
+Fresh `banker-income --nexus-cards` now composes the existing deferred normal
+Skill band with classic Basic/Advanced all14/all12 setup, optionally original
+Tech3+ and Advanced Strongholds2+. Actual bank payer legs still qualify once
+per phase; player income and phase-end Tech payouts do not qualify, and the

+outside this entry. [Source, original costs and runtime proof](SPICE_BANKER_RUNTIME.md#classic-nexus-income-composition--13-october-2026).
