To provide a clear hierarchy, policies are organized into three tiers. Each tier
has a designated number that forms the base of the final priority calculation.

| Default | 1 | Built-in policies that ship with the Gemini CLI. |

This system guarantees that:
- Admin policies always override User and Default policies.
- User policies always override Default policies.
- Admin policies always override User, Workspace, and Default policies.
- User policies override Workspace and Default policies.
- Workspace policies override Default policies.
- You can still order rules within a single tier with fine-grained control.
For example:
- A `priority: 50` rule in a Default policy file becomes `1.050`.
- A `priority: 100` rule in a User policy file becomes `2.100`.
- A `priority: 20` rule in an Admin policy file becomes `3.020`.
- A `priority: 10` rule in a Workspace policy policy file becomes `2.010`.
- A `priority: 100` rule in a User policy file becomes `3.100`.
- A `priority: 20` rule in an Admin policy file becomes `4.020`.
