feat(weight-custody-manifest): add WCM demo catalog - #61
Merged
Conversation
Relocate the Weight Custody Manifest demos into a per-product scenario folder, depending on the published PyPI package (weight-custody-manifest >=0.19.0) instead of the in-repo SDK. Mirrors the ca2a-delegation layout. Four demos: open_model_e2e (full 6-step flow on an open model), sovereign_self_custody (2-of-3 threshold release), snp_replay (offline SEV-SNP quote replay against a committed synthetic bundle), and real_open_model (downloads SmolLM2-135M and hashes real weights, run local). README adapted from the WCM tutorials. A CI job installs from PyPI and runs the three offline demos; real_open_model is excluded (network, heavy) with its extras in requirements-infer.txt.

Adds a
weight-custody-manifest/scenario folder, relocating the WCM demos here now that the SDK is published on PyPI. They depend onweight-custody-manifest>=0.19.0from the index rather than an in-repo checkout, mirroring theca2a-delegation/layout.Contents
open_model_e2e.py— full six-step custody flow on an open model (mock attestation): joint manifest signing, attestation-gated release, wipe-on-lapse, license, derivative + lineage.sovereign_self_custody.py— 2-of-3 threshold split-key release (SPEC 3.5).snp_replay.py— offline SEV-SNP quote replay against a committed synthetic bundle (fixtures/snp_quote_synthetic.json).real_open_model.py— downloads SmolLM2-135M and hashes its real safetensors, with a tamper demo and optional--infer. Run-local (network, heavy); extras inrequirements-infer.txt.README.mdadapted from the WCM tutorials; setup ispip install weight-custody-manifest.CI
