feat(demo-06): weight custody talk-track demo - #28
Merged
Conversation
Add a sixth demo depending on the published weight-custody-manifest package (>=0.19.0). A pure in-process WCM flow with a software (mock) attestation provider: a manifest binds the exact weight hash and is jointly signed, the attestation gate releases the key only for the certified serving stack, a tampered checkpoint is refused before load, and a fine-tune's lineage verifies back to the signed base. Runs with no hardware and no server. Wire it into demo.py (choice 6 + narration) and requirements.txt, and broaden the README (six demos across cMCP, TRACE, and WCM).

What
Adds a sixth demo to the talk track, now that the WCM SDK is on PyPI. Demos 1-5 govern what an agent does; demo 6 is the layer beneath, the model weights themselves.
