# Example: Orchestrator Configuration - Solo Mode (Single Developer)
#
# This example shows a minimal orchestrator setup for a single developer.
# Features:
# - Filesystem-based storage (no external dependencies)
# - Minimal resource consumption
# - Simplified monitoring (logs only)
# - Development-friendly logging (debug level)
#
# Usage:
#   nickel export --format toml orchestrator-solo.ncl > orchestrator.solo.toml
#   ORCHESTRATOR_CONFIG=orchestrator.solo.toml cargo run --bin orchestrator
