Borrows carry a kind: while a value is mutably borrowed no new borrow starts, a mutable borrow is rejected while read-only borrows are alive, and a `&mut T` slot only accepts `&mut value`. Reference fields record their path (`B.n`) as the borrower, so `del` is blocked by nested and self borrows and released on `del`/reassign of the root. The table grows to 1024 rows and fails fast instead of silently dropping rows, and each function clears its rows at entry. `Box[T]`/`BoxT[T]` count as ownership spellings; own fields are released at scope exit (not only on `del`), for forward-declared and self-referential types too, behind a null guard. A move is only allowed into an `own` slot. Reference results use borrow elision (a reference parameter or `self`) instead of the `@life` advice, reference parameters no longer trip the stack-escape check, and `&` on an owned pointer yields the heap pointer (LIFE_HEAP).
