Third-party provenance and release boundary

This is an engineering redistribution inventory, not legal advice. File-level copyright and license notices remain authoritative.

Root distribution

The sdist and wheel contain the first-party teleboost/ package, declarative recipes/, and release tooling. They exclude all third_party/ trees, tests, smoke/diagnostic programs, weights, datasets, outputs, and checkpoints.

Component Distributed paths Recorded baseline License / handling
verl External dependency; thin adapters under teleboost/patches/ 0.7.1, immutable revision in constraints/upstreams/verl.txt Apache-2.0; not vendored in root artifacts.
NVIDIA Megatron-LM teleboost/engines/teletron/ and selected training/checkpoint files retaining NVIDIA headers 55ac7082517c3878ae653c07c09c534b8aed49f6 BSD-3-Clause upstream portions; full terms in LICENSES/Megatron-LM-BSD-3-Clause.txt.
OpenCLIP teleboost/models/offline_clip.py ea7718f927b84e1b46ce057d3eae5ca4c9c41434 MIT upstream portions; full terms in LICENSES/OpenCLIP-MIT.txt.
ModelScope DiffSynth-Studio Flow scheduler and Wan VAE ports scheduler 451aab01161496fd68510e7682306eaf54ff97f2; VAE ancestor 5be5c32fe4b240547a288afa4c29e3f81b6ef881 Apache-2.0; preserve attribution and modification notices.
Tele-AI TeleTron teleboost/engines/teletron/, teleboost/models/wan/teletron/ 5fb0431bd9a42a14cf4ee5768d0a0482828e1ff5 Apache-2.0 ports; NVIDIA-derived files retain BSD notices.

The OpenCLIP and DiffSynth original import metadata was not retained. These commits are reproducible reconciliation baselines: OpenCLIP was compared across upstream release tags; the DiffSynth scheduler is a direct code match modulo documented changes; the VAE revision is the closest structural ancestor. A maintainer/legal reviewer must approve these reconciliations before the first public source tag. Packaging checks cannot make that authorship decision.

Source-checkout-only components

Local path Purpose and baseline Release handling
third_party/wan/ Alibaba Wan runtime, baseline 204f899b6436fe2e1705a0b67c464b30b8137799 Apache-2.0 license retained; excluded from root artifacts.
third_party/Videophy/ VideoPhy / mPLUG-Owl integration MIT directory license with embedded Apache-2.0 file headers; excluded.
third_party/raft/ Princeton RAFT runtime BSD-3-Clause license retained; excluded.

Optional VideoCLIP source is user supplied and not present by default. Its identified terms are non-commercial and must be reviewed independently.

Boundary enforcement

python tools/release/build_artifacts.py \
  --out-dir /tmp/teleboost-release-wan

The builder rejects non-Wan family code in the checkout, stages an allowlisted copy without rewriting product source, builds the wheel only from the extracted sdist, and rejects vendored source, tests, diagnostics, outputs, private path markers, missing attributions, or missing license texts.
