Struct BoundaryZone 

pub struct BoundaryZone {
    pub name: String,
    pub patterns: Vec<String>,
    pub auto_discover: Vec<String>,
    pub root: Option<String>,
}

A named zone grouping files by directory pattern.

Fields

name: String

Zone identifier referenced in rules (e.g., "ui", "database", "shared").

patterns: Vec<String>

Glob patterns (relative to project root) that define zone membership. A file belongs to the first zone whose pattern matches.

auto_discover: Vec<String>

Directories whose immediate child directories should become separate zones under this logical group.

For example, { "name": "features", "autoDiscover": ["src/features"] } creates zones such as features/auth and features/billing, each with a pattern for its own subtree. Rules that reference features expand to every discovered child zone. If patterns is also set, the parent zone remains as a fallback after discovered child zones.

root: Option<String>

Optional subtree scope for monorepo per-package boundaries.

When set, the zone’s patterns are matched against paths relative to this directory rather than the project root. At classification time, fallow checks that a candidate path starts with root and strips that prefix before glob-matching the patterns against the remainder. Files outside the subtree never match the zone.

Useful for monorepos where each package has the same internal directory layout: instead of writing packages/app/src/** and packages/core/src/** (which collide on shared zone names), set root: "packages/app/" and patterns: ["src/**"] per package.

Trailing slash and leading ./ are normalized; backslashes are converted to forward slashes. Patterns must NOT redundantly include the root prefix: root: "packages/app/" with patterns: ["packages/app/src/**"] is rejected with FALLOW-BOUNDARY-ROOT-REDUNDANT-PREFIX because patterns are resolved relative to the root.
