"""Main orchestration module for Finesse Benchmark Database Generator

This script serves as the 'Conductor' that orchestrates the entire pipeline: from configuration setup
through atomic bead generation to final JSONL serialization. It ties together config, chunker, and writer
for end-to-end execution of our 'Gemstone Necklace' production process.

Key Principles:
- Ensures all modules use the shared CONFIG for consistency.
- Executes chunking first (memory-intensive), then writing (I/O-focused).
- Comprehensive logging for audit trail and debugging.
- Designed for one-shot full generation; scale via external orchestration if needed.

Usage:
python main.py
# Runs the full pipeline: generates ~100,000 strings of beads and writes to probes_atomic.jsonl
