Edit object type properties

Editing properties is one of the highest-risk semantic changes because applications and workflows often assume property stability.

Current editable fields

The backend currently allows updates to:

• display_name
• description
• required
• unique_constraint
• time_dependent
• default_value
• validation_rules

The name and property_type are notably not part of the update contract, which is a strong signal that OpenFoundry is already protecting property identity and typing from casual mutation.

OpenFoundry current vs target

Dimension	Current	Target
edit flow	direct API mutation	guarded semantic migration workflow
validation	value validation exists	impact analysis across apps and workflows
compatibility	implicit	explicit compatibility checks and release notes
