Recap of changes:

AI Model

• Updated access.acls and access.identity_providers anchors to reflect v0.0.47 access wrapper restructuring
• Added explanation of per-model identity provider assignment (access.identity_providers) and the one-per-type constraint
• Updated entity example to use correct access.acls.allow object shape
• Changed "{{site.base_gateway}} priority documentation" link text to "plugin priority documentation"

AI Agent

• Updated access.acls anchor to reflect v0.0.47 access wrapper restructuring
• Updated entity example to use correct access.acls.allow object shape
• FAQ: replaced plugin terminology with AI Policy ("Can the same plugin run..." → "How do I attach AI Policies...", "Plugin configuration" → "Configuration")
• Prose: "logging plugins" → "logging AI Policies"

AI MCP Server

• Updated FAQ anchors for access wrapper fields (access.acl_attribute_type, access.default_tool_acls, access.acls, tools[].access.acls) to reflect v0.0.47 restructuring
• Updated entity example to use access.acl_attribute_type, access.acls.allow, and access.default_tool_acls.deny

AI Consumer Group

• FAQ and prose: clarified that for AI Models and AI Agents, access.acls accepts exactly one of allow or deny; AI MCP Servers support setting both simultaneously

AI Vault

• Added AI Identity Provider to related_resources
• FAQ Q3: added AI Identity Provider to the list of entities with vault-referenceable fields
• Sensitive fields table: added AI Identity Provider row (OIDC client secret for openid-connect type providers)

Just nitpicks! I saw a few lowercase "consumer", but I think some of them might be referring to the general notion of any consumer of an AI.
