feat(weight-custody-manifest): comprehensive per-feature example catalog - #64
Merged
Conversation
Add eight focused examples covering the full WCM feature surface across both open- and closed-weight framings, each depending on the published PyPI package and wired into CI: - closed_model_e2e / open_model_e2e: the closed (secrecy) vs open (integrity, license, derivative custody) framings, side by side. - multi_stage_byom: SPEC 3.8 sequential re-custody, monotone rights, cascading revocation. - revocation_kill_switch: revoke then wipe on the next cadence lapse. - channel_binding: CVE-2026-33697 relay defense (sealed key release). - transparency_log: RFC 9162 inclusion + consistency + suppressed- revocation detection. - post_quantum: ML-DSA-65 and the Ed25519+ML-DSA-65 hybrid. - provenance_model_signing: the OpenSSF model-signing interop (needs the [model-signing] extra). - quote_verification: the verifier machinery against a synthetic PKI. Bump requirements to >=0.21.0, add a CI step per example (provenance installs the model-signing extra), and reorganize the README around the open-vs-closed framing and the feature groups.

What
Expands the WCM examples folder from a handful of demos to a per-feature catalog covering the full surface, across both open-weight and closed-weight framings. All depend on the published PyPI package (
weight-custody-manifest>=0.21.0) and run in CI.New examples (8)
closed_model_e2e.py/open_model_e2e.py— the closed (secrecy is the job) vs open (integrity, license, derivative custody) framings, side by side.multi_stage_byom.py— SPEC 3.8 sequential re-custody: chainedderived_from, monotone rights, cascading revocation.revocation_kill_switch.py— revoke, then the enclave stops at the next cadence lapse (key zeroized, not suspended).channel_binding.py— CVE-2026-33697 relay defense: the released key is sealed to the enclave's attested transport key.transparency_log.py— RFC 9162 inclusion + consistency proofs and suppressed-revocation detection.post_quantum.py— ML-DSA-65 and the Ed25519+ML-DSA-65 hybrid.provenance_model_signing.py— the OpenSSF model-signing interop (verify_provenance), needs the[model-signing]extra.quote_verification.py— the verifier machinery (cert chain + signature + nonce) against a synthetic PKI, passing and failing.Wiring
requirements.txtbumped to>=0.21.0.weight-custody-manifestjob; the provenance step installs the model-signing extra first.Verification
Every new offline example was run locally in a clean venv against the published 0.21.0 package (with the
[model-signing]extra for provenance): all exit 0. No em dashes.Note: the catalog builder stalled on a transient stream error after writing all eight scripts; I verified each runs, then did the requirements/CI/README wiring and this PR.
