| = help: this indicates a potential bug in the program: it performed an invalid operation, but the Tree Borrows rules it violated are still experimental |
| = help: the accessed tag <TAG> has state Reserved (conflicted) which forbids this child write access |

| help: the accessed tag <TAG> later transitioned to Reserved (conflicted) due to a foreign read access at offsets [0x0..0x4] |
