# Preserved notices and source references

These files preserve relevant notices alongside the engineering application.
They do not relicense the supplier firmware or establish a complete license
inventory for proprietary supplier libraries. The source tag retains the
original source headers and library provenance.

| Included file | Origin |
| --- | --- |
| `nRF5_Nordic_license.txt` | Preserved factory distribution `artifacts/ring-firmware/603v1.23.2-6.0.3.3z62/licenses/nRF5_Nordic_license.txt`. |
| `nrfx-LICENSE` | `firmware/BCL603S2X/app/modules/nrfx/LICENSE`. |
| `freertos-license.txt` | `firmware/BCL603S2X/app/external/freertos/license/license.txt`. |
| `littlefs-header-notice.txt` | Copyright/SPDX header retained from `firmware/bc_ros/bc_module/file/LittleFS/`. |
| `littlefs-LICENSE.md` | Verbatim upstream v2.9.0 license; vendor `LFS_VERSION` is 2.9. There was no separate LICENSE file in the vendor LittleFS directory. |
| `gcc-Copying.html` | Pinned Arm GNU 15.2.rel1 installation, `share/doc/gcc/Copying.html`; general GPLv3 copying text. |
| `gcc-COPYING.RUNTIME` | Verbatim GCC 15.2.0 upstream Runtime Library Exception 3.1, supplementing the general copying text. |
| `newlib-COPYING.NEWLIB` | Verbatim upstream newlib-4.5.0 COPYING.NEWLIB; installed `_NEWLIB_VERSION` is 4.5.0. Includes component-specific notices, not a claim every component is linked. |
| `arm-none-eabi-readme.txt` | Pinned toolchain `share/doc/arm-none-eabi/readme.txt`. |
| `upstream-sources.json` | Exact URLs for the three supplemental upstream texts retrieved 2026-09-06. |

Upstream supplement URLs identify the license text only; they do not establish
that supplier-patched code or the Arm toolchain exactly matches an upstream
source tag. The binary identity is defined by the release's CI provenance.
The installed toolchain did not include separate runtime-exception or Newlib
redistribution files, so the upstream texts are included separately.

Micro-ecc is disabled in the candidate and absent from the checked CI ELF;
its source license remains in the source tree. This bundle contains no
SoftDevice or bootloader binary. The original factory distribution preserves
their separate notices. Preserve all notices when repackaging for bench use.
