pub const PERSONAL_PALACE: &str = "personal";Expand description
Sentinel palace name that is always valid regardless of project context.
Why: users operating outside any project root (global notes, exploratory
sessions, personal task lists) need a stable palace that can receive
memories without failing the project-enforcement gate. The name personal
is the single reserved identifier for this purpose.
What: a &str constant that the enforcement logic tests against before
applying project-slug validation.
Test: project_slug_personal_always_allowed.
