* with Pro-locked option choices, from a flagged schema tree. |

| 841 |
* A `fieldset` pushes its own id onto the path (its children save nested |

* `group`/`repeater` sub-fields never save as flat keys — their values nest |

* per-row inside the parent's own list, and a locked parent is stripped by |
| 845 |
* its own path — so their sub-fields are not descended into (same rationale |
| 846 |
* as Chat Help's collect_pro_ids). |
