Full rewrite of all 13 wiki pages against current src/ surface
Realigned with the post-ft/metrics-ensemble model/ refactor: dropped
references to removed ModelTrainer/ModelPredictor/ModelEvaluator/
MultiModelEvaluator and the old extract_features → train → forecast API;
documented the current TrainingModel/PredictionModel/EvaluationModel +
MetricsEnsemble stack, the BaseModel + CacheModel mixin pattern, and the
scenarios.py workflow.
Deleted 5 superseded pages (Installation, Quick-Start, Classifiers-and-CV,
Evaluation-and-Forecasting, Training-Workflows). Created 5 new pages
(Getting-Started, Usage, Training-Workflow, Prediction-Workflow,
Evaluation-Workflow). Rewrote 8 in place (Home, Data-Sources,
Pipeline-Walkthrough, Visualization, Configuration, Output-Structure,
Architecture, API-Reference). Final count 13 pages; no dead old links.
