[Possible Roadmap] Standardize intent schema, wire schema, and normalization patterns for modules

[MehmetSecgin]

Summary

Define whether intent schema, wire schema, and normalization should become standard patterns in external dispatch modules.

Why

Real modules need a clean way to separate:

• intent-facing payloads
• transport/wire payloads
• normalization/translation logic

Without a standard pattern, each module will solve this differently and external modules will drift.

Direction to explore

• use Zod as the long-term schema model for external modules
• provide SDK guidance or helpers for intent schema vs wire schema boundaries
• define where normalization logic should live in module structure

Questions to resolve

• Should this be a convention only, or an SDK-supported pattern?
• How opinionated should dispatch be about wire-shaping helpers?
• What is the minimal useful standard that still keeps modules ergonomic?
