Re: Call for Co-Editors: Post-Quantum Migration Pattern for Verifiable Credentials (Ed25519 + ML-DSA Dual-Signature Model)

Hi Amir, all,
I'd like to volunteer for the co-editor / contributor pool for this work item (and the broader "Cryptographic Continuity and Post-Quantum Transition Patterns" proposal).
We operate Jiaozi Protocol, an identity and attestation layer for AI agents (introduced on this list last week in the transparency-log design review thread). Two things we can bring that may be useful:

 * 
A live case study in multi-suite coexistence. For regulatory reasons our production issuing service already runs two cryptographic regimes side by side today: Ed25519 + SHA-256 for international verifiers, and the Chinese national suite (SM2 signatures + SM3 digests) as co-signatures on the same status credentials for domestic verifiers — dual digests, dual proofs on identical canonical bytes (JCS), and verifiers that must decide what to do when they only understand one of the two suites. This is structurally the same problem as the Ed25519 + ML-DSA transition, except we hit the verifier-behavior, key-distribution and canonical-byte-stability questions in production every day. Happy to write these operational lessons into the migration-pattern and verifier-behavior sections.

 * 
Test vectors and implementation reports. Our specs ship with conformance vectors and a runner (status credential suite is public in our repo), and we plan to adopt the dual-proof Ed25519 + ML-DSA profile in our own stack — so the document's guidance would get a production implementation report, not just review comments.
Time commitment: a few hours weekly for editing and calls is fine.
Thanks,
