+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this

+# AGX Open
+
+AGX Open is the public, experimental SDK for learning and prototyping portable compute concepts in Free Pascal.
+
+This repository is a **clean public implementation**. It does not contain the proprietary AGX policy engine, optimization algorithms, internal scheduler, cache system, mesh enhancement system, interception layer, or commercial rendering backend.
+
+## Current features
+
+- Device and backend abstraction
+- Safe buffer allocation, upload, and download
+- CPU reference kernels
+- CUDA-like submit-and-dispatch learning model
+- Small examples that compile independently
+
+## Build
+
+Requirements: Free Pascal Compiler 3.2 or newer and `make`.
+
+```sh
+make
+make test
+```
+
+## Run
+
+```sh
+./build/hello_device
+./build/compute_demo
+```
+
+## Architecture
+
+Applications use the public runtime API. The included CPU backend is intentionally simple and readable. Future community backends may target Metal, Vulkan Compute, or DirectCompute without changing application code.
+
+## Project status
+
+Experimental. The API may change before version 1.0.
+
+## Trademark
+
+The license covers source code, not the AGX or Agila names, logos, or branding. See `TRADEMARKS.md`.

+- [ ] Start from this clean directory, not the private repository history.
+- [ ] Confirm no private units or internal notes are present.
+- [ ] Run a secret scanner against files and Git history.
+- [ ] Run `make test`.
+- [ ] Confirm the copyright owner and license choice.

+# Public Architecture
+
+AGX Open contains only four public concepts:
+
+1. **Device** — selects a supported execution backend.
+2. **Buffer** — stores input or output data.
+3. **Kernel** — describes a user-supplied computation.
+4. **Dispatch** — runs a kernel over a requested number of elements.
+
+The bundled reference backend executes kernels on the CPU. It exists for education, testing, and API experimentation. It does not reproduce the private AGX engine.

+# Open and Closed Boundary
+
+## Included in AGX Open
+
+- Public data types and runtime interfaces
+- CPU reference implementation
+- Examples, templates, tests, and documentation
+- Extension points for future public backends
+
+## Not included
+
+- AGX policy and decision engine
+- Hardware profiling rules
+- Internal workload scheduler
+- Proprietary rendering backend
+- Mesh reconstruction, enhancement, optimization, validation, and LOD algorithms
+- Private cache algorithms
+- API interception or translation implementation
+- Internal bridges and commercial integration code
+- Private roadmaps and engineering notes
+
+Do not copy files from the private engine into this repository. New contributions must be independently written for the public SDK.
