.github/workflows/
  pages.yml             builds and deploys the documentation to Pages
Dockerfile              overlay: copies src/ on top of the base image
build.sh                check (tests) + build of the customized image
pyproject.toml          light_olt package metadata
README.md               introduction and quick start
NOTICE.md               distribution boundary and third-party notices
src/
  ecli                  eCLI executable (SSH login shell)
  light_olt/            Python package with the eCLI logic
  daemons/
    onu_dhcp.py         ONU DHCP subscribers (DORA/SARR)
    onu_optics.py       per-ONU optical levels (operational)
    ipfix_exporter.py   synthetic IPFIX telemetry
tests/                  overlay unit tests
seeds/
  onts_oper.xml         synthetic ONU inventory for LT1
  onts_oper_gpon_xgs.xml
                        synthetic GPON/XGS-PON inventory for LT2
examples/
  lab.clab.yml          containerlab lab: BNG + OLT + proxy
  docker-compose.yml    minimal smoke test: OLT + proxy
  config-bng/
    bng.txt             example Nokia SR OS BNG configuration
website/                this documentation (Docusaurus, es/en)

The files under seeds/ are editable operational-inventory fixtures for the lab. They are not exports of the base image's factory seeds. examples/config-bng/bng.txt configures the example BNG node; users must provide their own Nokia SR OS image and license.

Paths inside the image

The base image's startup supervisor expects components at fixed paths. The Dockerfile honors them; move them and the daemons won't start.

Repo source	Image destination
src/ecli	/usr/local/bin/ecli
src/light_olt/	/opt/light-olt/light_olt/
src/daemons/onu_dhcp.py	/usr/local/bin/onu_dhcp.py
src/daemons/onu_optics.py	/usr/local/bin/onu_optics.py and /usr/local/lib/olt/onu_optics.py

What is not here

YANG models, device extensions, factory or configuration seeds, precompiled sysrepo repositories, capability allowlists and the proxy source live in the base images. See the distribution boundary.
