Features

• modeling: cascade legality rules across known descendants (#452) (2ccb773)

  Declare a shared business rule once on a Model and apply it to that Model and its locally known descendants. For example, a closed Project can prevent further changes to its Tasks and their children:

  @AssertLegal(cascade = true)
  void assertOpen() {
      if (closed) {
          throw new IllegalCommandException("This project is closed.");
      }
  }

  Normal payload and context injection remains available. Use allowedClasses to select payload families, @Parent(validateAncestors = false) to stop one inheritance route, or @Apply(ancestorValidation = AncestorValidation.DISABLED) to permit a particular child mutation.

  The SDK checks all enabled known parent routes, including both sides of a move and automatically deleted children. Ancestor reads participate in atomic conflict validation: RETRY reevaluates and guarded ACCEPT attempts use FAIL to prevent stale permission. Replay does not execute these assertions.

  This feature is opt-in and SDK-side; writers need the relevant Model classes and rules. It adds no new Runtime protocol requirement. The developer guide and Java/Kotlin agent guides explain timing, exceptions, concurrency and performance.

• modeling: guard known descendants with cascading assertions (9c19cc7)

  Allow Model-owned legality rules to guard known parent routes with explicit relationship and Apply exceptions. Protect validation reads across compound changes, automatic deletions and concurrent reparenting; reject guarded ACCEPT conflicts instead of retaining stale permission.
