# Workspace Cross-Repo ProjectReference Guard

## Purpose

Prevent regression of cross-repo source coupling by failing fast when any `.csproj` in `greenfield/` references a project outside its own repository root.

## Script Location

- `tools/validate-no-cross-repo-projectrefs.sh`

## Usage

Run from within `greenfield/blueprint-platform`:

```bash
./tools/validate-no-cross-repo-projectrefs.sh
```

Run from the workspace root:

```bash
greenfield/blueprint-platform/tools/validate-no-cross-repo-projectrefs.sh
```

## Behavior

- Exit code `0`: no cross-repo `ProjectReference` entries found.
- Exit code `1`: one or more violations were found and listed.

## Enforcement Guidance

- Execute this guard before merge to `development`.
- Keep only intra-repo `ProjectReference` entries.
- Use package references for cross-repo consumption.
