  # Carry this result's presentation for an ancestor to prefix onto (header aggregation). Scoped
  # to `call!` — transparent bubbling — on purpose: a child run via plain `.call` must NOT leave a
  # carried presentation, or an explicit `.call` + re-raise (e.g. `step`'s bug path) would leak it
  # into the parent. Two gates: (1) only when an Axn ancestor is still on the stack to consume it
  # — at the OUTERMOST `call!`, `call` above has already unwound NestingTracking (and run its
  # reset), so a write here would have no consumer and no later reset (a thread-local leak that
  # also pins the Failure's __originating_action/context); (2) only when a base/reason was actually
  # declared, so a baseless fallback contributes nothing.
