Struct EntityPatch 

pub struct EntityPatch {
    pub name: Option<String>,
    pub description: Option<Option<String>>,
    pub properties: Option<Value>,
    pub tags: Option<Vec<String>>,
    pub entity_type: Option<Option<String>>,
}

Patch for update_entity. Only Some(_) fields are applied; None means “leave unchanged”.

For description:

• None (outer) — leave the current description as-is
• Some(None) — clear the description (set to NULL)
• Some(Some(s)) — set the description to s

For properties (deep-merge semantics):

• None — leave properties as-is
• Some(value) — deep-merge value into existing properties. Keys present in the patch overwrite existing keys; keys absent from the patch are preserved. Removing a key requires explicit replacement of the parent object (or a future unset/null-marker extension).

For tags — replace semantics: Some(vec) sets tags to exactly vec. To add a tag without losing existing tags, read the entity first, push the new tag, and pass the full list back.

For entity_type — ADR-014 tri-state: None leaves the current type unchanged, Some(None) explicitly clears it, and Some(Some(value)) validates and normalizes value through the installed entity-type registry.
