# ESP32 Swarm Provisioning — ADR-065/066
#
# Provisions multiple ESP32-S3 nodes for a hotel happiness sensing deployment.
# Each node gets WiFi credentials, a unique node_id, zone name, and Seed token.
#
# Prerequisites:
#   - ESP-IDF Python venv with esptool and nvs_partition_gen
#   - Firmware already flashed to each ESP32
#   - Seed paired (obtain token via: curl -X POST http://169.254.42.1/api/v1/pair)
#
# Usage:
#   bash provision_swarm.sh
