sense 1.2.0 (2026-09-08)

• Replaced all mlr3pipelines graph and PipeOp usage with an internal mlr3 regression learner providing fitted preprocessing, three-fold out-of-fold stacking, optional base-learner selection, and averaging or learned stacking. The package no longer needs mlr3pipelines to install, load, train or predict.
• Removed the mlr3viz, visNetwork, tictoc, forcats, readr, lubridate, purrr and Metrics dependencies. Mapping, timing, regression metrics, categorical processing and pipeline diagrams now use internal/base R code. R6 is now declared directly for the internal mlr3 learner.
• Moved mlr3filters to Suggests; correlation and variance are internal. Specialized filters still use their original optional backends, preserving their algorithms. Removed unused direct suggestions of mlr3misc and nloptr.
• Preserved the sense() arguments and result element names. plot is now a sense_pipeline object, drawn with plot(result$plot), rather than an HTML widget. time_log is a base R difftime. java_mem is accepted but unused. Stored model internals no longer have the GraphLearner/PipeOp layout.
• Fixed deployment predictions to use a model refitted on all supplied rows, independently of outer evaluation. Fit preprocessing and feature selection inside every stacking fold; perform benchmarking inside each ensemble fit rather than selecting algorithms using the full data before outer evaluation. Benchmark scores are now out-of-fold scores and respect the measure's direction.
• Added handling for unseen categories, constant/all-missing numeric columns, stable prediction schemas, finite input validation and reproducible fitting without changing the caller's random state or Java options.
• Bound nearest-neighbour tuning by the smallest training split, avoid invalid zero SVM nu/eta candidates, and let ranger choose mtry for each encoded schema. Random search is capped by both budget and n_evals; one-candidate batches prevent overshooting the evaluation cap. Time limits are checked between trials.
• Added base R regression and integration tests and a runnable migration vignette describing the architecture, optional dependencies and compatibility changes.
• Converted the migration vignette from PDF/LaTeX (.Rnw) to a knitr HTML vignette (.Rhtml), so building and checking the package no longer requires a LaTeX installation or Ghostscript.
