SPDX-License-Identifier: AGPL-3.0-only

PanAEC Engine accepts contributions that improve the engine while preserving strict open-source, professional, and security boundaries.

Required Terms

Contributions must be licensed under AGPL-3.0-only.
Contributors must own the submitted work or have permission to submit it.
Contributions must not add GPL-incompatible, AGPL-incompatible, proprietary, or unclear-license runtime dependencies.
Proprietary format support must be implemented through lawful adapter boundaries, not copied SDK internals or reverse-engineered protected code.
Code execution features must be sandboxed, bounded, logged, and disabled by default unless a deployment explicitly enables them.
If the maintainer requests copyright assignment for a contribution, the change cannot be merged until the assignment is completed in writing.

Add or update registry entries for new formats and capabilities.
Add JSON Schema, tests, and audit metadata for new worker routes.
Preserve source file identity, checksums, units, coordinates, route, adapter, and derivative provenance.
Never mark an output as compliant, submission-ready, construction-ready, or production-ready without a cited rule set and validator route.
Keep BIM, CAD, PDF, Office, media, archive, and code-programming routes separated by adapter and security boundary.
