Add the Nuoshuitong documentation outputs to the project progress ledger so the documentation lane has a traceable handoff point for review and follow-on implementation work.
Constraint: Keep this update limited to governance tracking for the newly added Nuoshuitong design pack
Confidence: high
Scope-risk: narrow

Add a Nuoshuitong documentation set covering the implementation checklist, split interface spec notes, normalized enums, and database/DDL guidance so follow-on integration can start from a consistent source of truth.
Constraint: Current phase is documentation-first and must not require backend/frontend code changes
Rejected: Merge the material directly into formal master design docs now | would broaden scope before the integration model and dialect strategy are reviewed
Directive: Treat these guides as integration-layer inputs until they are reconciled with formal technical design masters
Confidence: high
Scope-risk: moderate

Document the existing REV-002 backend billing-generation path and preserve a conservative partial-implementation judgment so the design stays aligned with current code evidence.
