azure-la-attach-user-mi

Attach a user-assigned managed identity to a Logic App (assign/action + workflows/write or sites/write).

match

A conjunctive graph pattern. Variables (?x) bind node ids; every clause must hold.

source	`<principal>`
target	`<Logic App workflow (existing or new)>`
permissions	`Microsoft.ManagedIdentity/userAssignedIdentities/assign/action` `Microsoft.Logic/workflows/write`

state logic	ACTIVE when BOTH permissions are confirmed at their respective scopes and role_compatible(?userMI, ?workflow) holds. POTENTIAL(role_compatibility) when the assign/action scope excludes the target MI. BLOCKED if a deny assignment covers either action.

Narrative

{principal.name} can attach user-assigned managed identity {userMI.name} to Logic App {target.name} (assign/action + workflows/write), binding a higher-privilege identity to the workflow.
