atwine/Metadata-Harmonisation-Tool: 0.4.3 - 2026-03-12

Added Map Studies: Group all transformation controls under a collapsible "Transformation" expander to reduce visual clutter. File: app/components/map_study.py Upload Codebook: persistent "Last codebook upload" banner (filename, variable count, timestamp) saved to input/target_variables.meta.json so status survives restarts. File: app/components/upload_codebook.py Changed Map Studies: default both "Relational Mode" and "Transform Mode" to OFF for a cleaner first-run experience. File: app/pages/4_Map_Studies.py Fixed Upload Codebook: submit button no longer remains disabled after selecting a file inside a form; server-side guard prevents empty submits. File: app/components/upload_codebook.py Upload Codebook: button label updated to "Upload Codebook" for clarity. File: app/components/upload_codebook.py Documentation Restructured README into a unified "Quick Start" with a clear choice between Option A (Docker) and Option B (No Docker). Moved the non-Docker (Conda/Micromamba) setup out of Development into Quick Start and added a conda init note (PowerShell/cmd/bash). Centralized guidance to set OLLAMA_BASE_URL in .env (Streamlit reruns can reset sidebar fields) with recommended values; added model pull steps for container and host; included a short "Verify your setup" step.
