On-Chain Enforcement of Super Validator Locking and Long-Term Commitment #269 - Milestones and Deliverables

Milestones and Deliverables

M1: Technical Design + Splice Maintainer Sign-Off

Timeline: Months 1–3

Focus: Produce a technical design doc, a complete implementation plan, and an initial draft Daml model that together satisfy the WG functional requirements within Splice architecture and win maintainer buy-in.

Deliverables:

• Design doc specifying: splice-api-* interface package surface, contract templates, trigger topology, authorization model, multi-custody aggregation approach, Phase 1-to-2 migration path, implementation path decisions and refinement, devnet/testnet strategy
• Interface package specification reviewed by Splice maintainers
• Draft Daml PR with core locking primitive templates and passing unit tests
• Community review allowing WG members to review design doc and provide input before finalization
• SV alignment workshop with representative cross-section of custody profiles
• Governance vote scope defined for the eventual Mainnet deployment (executed under the Implementation Phase proposal)

Acceptance criteria:

• Written sign-off from DA Splice team on the design doc
• Community review completed (WG member feedback addressed or documented)
• Unit tests passing in CI for the M1 Daml PR
