Module validation 

Validation layer for NAP structured merge.

Three stages:

Stage 1 — SDL validation Ensure the SDL document itself is valid:

• Valid merge strategy for each property
• Required fields exist
• Identity keys defined where required
• Property names don’t contain dots (V1 limitation)

Stage 2 — Manifest validation Ensure the manifest conforms to the SDL:

• Required fields are present
• Types match the schema

Stage 3 — Merge strategy validation Ensure merge strategies have all required metadata:

• ordered_unique has identity rule
• edge_list has source_key, target_key, identity rule

All validation MUST complete before persistence.
