mfrmr 0.1.5

Maintenance release

Reworked print(fit), summary(fit), and summary(diagnose_mfrm(...)) so results start with Status, Key warnings, and Next actions.
Added a clearer recommended workflow in the README and help pages: fit with MML, review diagnostics with diagnostic_mode = "both", then move to reporting helpers.
Improved ordered-score handling and guidance, including binary two-category use, rejection of fractional score values, non-consecutive score-code mapping through score_map, and clearer warnings for retained zero-count categories.

Added the first public latent-regression MML branch for ordered RSM / PCM fits with person covariates, including simulation and scoring support for the fitted population model.
Added bounded GPCM support for the documented direct route, including core summaries, diagnostics, plots, posterior scoring, and information checks, while keeping unsupported downstream routes explicit.
Extended ordered-response support and documentation for binary RSM / PCM use, fixed-calibration scoring after JML, and PCM information curves.

Added strict marginal follow-up plots through plot_marginal_fit() and plot_marginal_pairwise().
Strengthened the reporting surface with reporting_checklist(), build_summary_table_bundle(), export_summary_appendix(), and visual_reporting_template() for manuscript-oriented tables, appendix artifacts, and figure-placement guidance.
Added structured caveats in summaries and appendix tables for retained zero-count score categories and latent-regression population-model omission/design issues.
Added exploratory plot(fit, type = "ccc_surface", draw = FALSE) output for advanced visualization while keeping 2D Wright/pathway/category plots as the default reporting route.

Added scoped ConQuest overlap helpers and concise software-scope summaries for FACETS, ConQuest, and SPSS handoffs.
Clarified latent-regression reporting outputs so coefficient reporting is kept separate from post hoc score regression.

Replaced a misencoded author name in documentation references so the PDF manual builds cleanly under CRAN’s LaTeX checks.
Revised DESCRIPTION references again to avoid incoming spell-check notes while preserving the requested author-year-doi citation format.

Revised DESCRIPTION references to use the requested authors (year) <doi:...> format.
Added a documented return-value section for facet_quality_dashboard(), including the output class, structure, and interpretation.
Replaced \dontrun{} with \donttest{} for executable examples so CRAN can exercise those examples during checks.

Further reduced CRAN check time by trimming the CRAN-only test subset to lightweight smoke tests after the incoming pretest still reported a Windows overall-checktime NOTE for version 0.1.1.

Revised DESCRIPTION metadata to avoid CRAN incoming spell-check notes on cited proper names.
Reduced CRAN check time by skipping long integration and coverage-expansion test files during CRAN checks while keeping the full local test suite.

Native R implementation of many-facet Rasch model (MFRM) estimation without TAM/sirt backends.
Supports arbitrary facet counts with fit_mfrm() and method selection (MML default, JML).
Includes FACETS-style bias/interaction iterative estimation via estimate_bias().
Provides fixed-width report helpers (build_fixed_reports()).
Adds APA-style narrative output (build_apa_outputs()).
Adds visual warning summaries (build_visual_summaries()) with configurable threshold profiles.
Implements residual PCA diagnostics and visualization (analyze_residual_pca(), plot_residual_pca()).
Bundles Eckes & Jin (2021)-inspired synthetic Study 1/2 datasets in both data/ and inst/extdata/.
