Environment Variable & Config Standardization Implementation Summary

---

[!NOTE] Historical evidence: results, counts, commands, and observations below belong to the original work described here. The editorial update date is not a new test or corpus verification. For present behavior, use current feature map.

Purpose

Standardize environment variable handling across the monorepo using a single source of truth defined in tools.yaml and loaded via dotenv.

Implementation Details

Configuration Source

• tools.yaml: Central registry of all externalizable environment variables.
• config/development.env: Default development values (gitignored).
• config/local.env: Local secret/override file (gitignored).
• config/README.md: Documentation for the new configuration structure.

Backend Changes (DAL & API)

• DatabaseConfigLoader.kt: Refactored to use dotenv-kotlin to load from ./config with standard precedence (Dev -> Local -> System Env).
• build.gradle.kts (DAL): Added libs.dotenv.kotlin dependency.

Frontend Changes (Vite)

• vite.config.ts: Updated envDir to ../../config to share environment files with the backend.
• package.json: Updated scripts and dependencies for environment alignment.

Documentation & Templates

• config.md: Updated canonical configuration documentation.
• steel-thread-runbook.md: Aligned setup instructions with the local.env workflow.
• quick-reference-auth.md: Updated authentication configuration steps.
• development.env.example: Provided a template for environment setup.
