Scenario Planning

Use this section when you want to compare historical, manual, and optimised future plans with abacus.scenario_planner.

The scenario planner is a higher-level planning surface than the low-level optimisation wrapper. It works in total horizon spend units, returns structured comparison tables, and includes a supported workspace app for fitted runs.
