//| gets one base. So the signal OWNS one of these instead, and hands |
//| it to any collaborator that needs to read training data.          |
//|                                                                  |
//| Every method here is a forward. That is the entire point: this is |
//| the only file that has to change when the signal renames a cache, |
//| and no collaborator has to change at all. It holds a borrowed     |
//| pointer and never frees it - the signal outlives its own adapter  |
//| by construction.                                                  |
