Changes in version 0.0.0.9000                      

Major Changes (2025-12-15)

Selective Loading Strategy (v0.1.0 preparation)

Breaking Change: mediationverse now uses selective loading - only medfit
(foundation package) is loaded by default. Other packages must be loaded
explicitly.

Why this change?

  - Clean namespace with minimal function conflicts
  - Users load only packages they need
  - Explicit > implicit (better code clarity)
  - Coordinated with medfit ecosystem integration

Migration:

# OLD behavior (v0.0.x)
library(mediationverse)  # Loaded all 5 packages

# NEW behavior (v0.1.0+)
library(mediationverse)  # Loads only medfit
library(probmed)         # Load explicitly as needed
library(RMediation)      # Load explicitly as needed

New startup message:

── Attaching mediationverse 0.0.0.9000 ──
✔ medfit 0.1.0 (foundation package)
ℹ Use library(probmed) for P_med effect size
ℹ Use library(RMediation) for DOP/MBCO inference
ℹ Use library(medrobust) for sensitivity analysis
ℹ Use library(medsim) for simulation utilities

Documentation Improvements

  - Architecture diagrams: Added comprehensive ecosystem architecture
    and data flow diagrams to README
  - Vignettes updated: All vignettes now demonstrate selective loading
    pattern
      - getting-started.qmd: Updated with selective loading explanation
        and examples
      - mediationverse-workflow.qmd: Complete workflow showing explicit
        package loading
  - Testing documentation: Added SELECTIVE-LOADING-TEST.md with
    comprehensive test results

Implementation

  - R/attach.R: Refactored to load only medfit by default
  - R/zzz.R: Updated .onAttach() with informative startup message
  - All utility functions (mediationverse_packages(),
    mediationverse_conflicts()) tested and verified

Coordination

  - Aligned with medfit COORDINATION-BRAINSTORM.md (Option 2 strategy)
  - Ready for medfit v0.1.0 integration (ETA Dec 21, 2025)
  - Progress: 85% complete (waiting on medfit stabilization)

Bug Fixes

  - Fixed badge URLs in README.md to use correct GitHub organization
    case (Data-Wise instead of data-wise). Updated workflow badges and
    ecosystem package table for consistency
  - Fixed pkgdown workflow failure caused by version constraint on
    RMediation in DESCRIPTION. Removed (>= 1.4.0) constraint as it
    conflicted with pak dependency resolution in CI environments
  - Fixed documentation typo in mediationverse_packages() where the
    @return section had a missing closing parenthesis in the version
    field description (R/packages.R:13)

Workflow Optimization & Standardization (2025-12-05)

Performance Improvements

  - Optimized R-CMD-check workflow: Reduced from 5 to 3 platforms
    (macOS, Windows, Ubuntu release)
  - Removed problematic platforms: Dropped ubuntu-latest (devel) and
    ubuntu-latest (oldrel-1)
  - Runtime improvement: Check workflows now complete in ~3 minutes
    (down from 6 minutes, 50% faster)
  - Build optimization: Added --ignore-vignettes flag to skip vignette
    validation during CI checks
  - Removed Quarto installation: Not needed for CI checks, saves ~30
    seconds per run

Infrastructure Updates

  - Updated favicons: Regenerated all favicon assets to match updated
    logo
  - Added Gemini AI workflows: Code review, triage, and automated issue
    management
  - .Rbuildignore: Added ^CLAUDE\.md$ and ^STATUS\.md$ for documentation
    files
  - .gitignore: Added CLAUDE.local.md, *.Rcheck/, *.tar.gz for better
    local development

Standardization

  - All workflows passing on main branch
  - Consistent with ecosystem badge standards
  - Website configuration aligned with mediationverse theme

mediationverse 0.0.0.9000

New Features

  - Initial package skeleton with core functionality
  - mediationverse_packages() - List installed ecosystem packages with
    versions
  - mediationverse_update() - Update all ecosystem packages from
    GitHub/CRAN
  - mediationverse_conflicts() - Detect and display function name
    conflicts
  - Startup message displays attached packages when loading
    mediationverse

Ecosystem

The mediationverse meta-package provides unified access to:

  - medfit - Infrastructure (S7 classes, model fitting, extraction,
    bootstrap)
  - probmed - Probabilistic effect size (P_med)
  - RMediation - Confidence intervals (Distribution of Product, MBCO)
  - medrobust - Sensitivity analysis (bounds, falsification)
  - medsim - Simulation infrastructure

Documentation

  - pkgdown website with standardized ecosystem theme
  - README with installation and usage instructions
  - Function documentation for all exports

Infrastructure

  - GitHub Actions for R CMD check
  - GitHub Actions for pkgdown deployment
  - Standardized package structure following tidyverse patterns
