  security notes.

  Keep this page a thin router. The root registry is the only environment
  variable table; do not duplicate names or behavior here. Preserve the
  reciprocal route so agents entering through the system manual can reach the
  canonical reference.

# Environment-variable registry router

The canonical environment-variable reference is the repository-root
[`ENVIRONMENT_VARIABLES.md`](../../../../../../ENVIRONMENT_VARIABLES.md).

Use that registry for the complete table, defaults, accepted values, scope,
read/reload timing, invalid-value behavior, implementation owners, and security
notes. This page exists only as a progressive-disclosure route from the system
manual; runtime source remains the behavioral authority.
