Fix caption cache timing, commit path tracking, and clean up start script

- Move caption cache refresh before UI render so indicators show on load
- Return actual dest paths from commit_batch/commit_global to fix
  caption-on-apply silently failing when files are renamed on collision
- Simplify start.sh to only run NiceGUI (remove Streamlit)
- Add requests to requirements.txt

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Turbo Sorter Pro v12.5 - A dual-interface image organization tool combining Streamlit (admin dashboard) and NiceGUI (gallery interface) for managing large image collections through time-sync matching, ID collision resolution, category-based sorting, and gallery tagging with pairing capabilities.
+
+## Commands
+
+```bash
+# Install dependencies
+pip install -r requirements.txt
+
+# Run Streamlit dashboard (port 8501)
+streamlit run app.py --server.port=8501 --server.address=0.0.0.0
+
+# Run NiceGUI gallery (port 8080)
+python3 gallery_app.py
+
+# Both services (container startup)
+./start.sh
+
+# Syntax check all Python files
+python3 -m py_compile *.py
+```
+
+## Architecture
+
+### Dual-Framework Design
+- **Streamlit (app.py, port 8501)**: Administrative dashboard with 5 modular tabs for management workflows
+- **NiceGUI (gallery_app.py, port 8080)**: Modern gallery interface for image tagging and pairing operations
+- **Shared Backend**: Both UIs use `SorterEngine` (engine.py) and the same SQLite database
+
+### Core Components
+
+| File | Purpose |
+|------|---------|
+| `engine.py` | Static `SorterEngine` class - all DB operations, file handling, image compression |
+| `gallery_app.py` | NiceGUI gallery with `AppState` class for centralized state management |
+| `app.py` | Streamlit entry point, loads tab modules |
+| `tab_*.py` | Independent tab modules for each workflow |
+
+### Database
+SQLite at `/app/sorter_database.db` with tables: profiles, folder_ids, categories, staging_area, processed_log, folder_tags, profile_categories, pairing_settings.
+
+### Tab Workflows
+1. **Time-Sync Discovery** - Match images by timestamp across folders
+2. **ID Review** - Resolve ID collisions between target/control folders
+3. **Unused Archive** - Manage rejected image pairs
+4. **Category Sorter** - One-to-many categorization
+5. **Gallery Staged** - Grid-based tagging with Gallery/Pairing dual modes
+
+## Key Patterns
+
+- **ID Format**: `id001_`, `id002_` (zero-padded 3-digit prefix)
+- **Staging Pattern**: Two-phase commit (stage → commit) with undo support
+- **Image Formats**: .jpg, .jpeg, .png, .webp, .bmp, .tiff
+- **Compression**: WebP with ThreadPoolExecutor (8 workers)
+- **Permissions**: chmod 0o777 applied to committed files
+- **Default Paths**: `/storage` when not configured
