Any Derivative Work must include this non-commercial restriction. You may
not re-license the Software or any Derivative Work under terms that permit
Commercial Use.
### 4. Copyleft (Share-Alike) Requirement
All Derivative Works must be licensed under this same License. You may not
distribute a Derivative Work under different license terms, whether more
permissive or more restrictive, without prior written permission from the
copyright holders.
This ensures that:
- All improvements, features, and bug fixes remain freely available
- No one can take the Software proprietary
- The community benefits from all contributions
### 5. Source Code Availability
If you distribute the Software or any Derivative Work in compiled form,
you must also make the complete corresponding source code available at no

Using the Software as a development tool within an organization is

offered to third parties.
(b) The Software is not offered as a hosted service to third parties.
(c) The organization does not charge others for access to the Software.
**Example of permitted Internal Use:** A software company installs CodeMap
to help its developers navigate their C# codebase. The company sells its
own products, but CodeMap is an internal tool — not part of what they sell.
**Example of prohibited Commercial Use:** A company packages CodeMap into
a cloud-based code analysis platform and charges customers for access.
**Example of prohibited Commercial Use:** A consulting firm sells
"CodeMap-powered code audits" as a service, where CodeMap is the primary
tool delivering the value.

WHETHER IN AN ACTION OF CONTRACT, TORT, OR OTHERWISE, ARISING FROM, OUT
OF, OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN
THE SOFTWARE.
### 9. Termination
This License and the rights granted hereunder will terminate automatically
if you fail to comply with any of its terms. Upon termination, you must
