Component: Legacy config loader

Responsibility

Load local configuration for the legacy PHP module. Expose helper access for DB, OpenAI, URLs, endpoints, and path values. Provide one DB connection factory used by web pages and worker.

Interfaces

• Input:
  • config/local.php if present
  • fallback config/local.example.php for shape and safe defaults
• Output:
  • config access helpers
  • mysqli connection helper
  • normalized path values for logs and routes

Dependencies

• PHP array config files
• mysqli
• module root path

Limits

• Does not manage secret rotation.
• Does not validate remote credentials.
• Does not redesign auth or downstream business logic.

Success criteria

• No tracked PHP file contains hard-coded DB or OpenAI secrets
• Entry points use shared config helper
• Local setup path is documented
