## Current State - Many configuration values are hardcoded in code - Default values scattered throughout codebase - Missing configuration validation ## Issues - Cannot configure for different environments (dev, staging, prod) - Hard to change settings without code changes - No validation of configuration values - Configuration errors only discovered at runtime ## Required - Externalize all configuration to config files or environment variables - Add configuration validation on startup - Document all configuration options with: - Description - Default value - Valid range/format - Required vs optional - Provide configuration templates for different environments - Fail fast on invalid configuration ## Location - `mobile-sensor-microservice/service.py` (default values - lines 25-31, 68-74) - `tpm-plugin/tpm_plugin_server.py` (default paths) - Test scripts (hardcoded IPs, ports) ## Related - #133 (Enhancement: Externalize hardcoded configuration defaults) - From PRODUCTION_READINESS_ANALYSIS.md - Section 4.1
