| 46 | * source as a third bypass route, but reading back the caller's own |
| 47 | * query string discloses nothing they don't already have. |
| 48 | * |
| 49 | * Returned explicitly rather than deferring to Base_Source, whose |
| 50 | * default is `! empty( $this->src() )`: that would make an empty $_GET |
| 51 | * fail the *permission* check and throw, when the correct outcome is |
| 52 | * simply "no such query var" - which get_result_on_prop() already |
| 53 | * reports on its own. |
| 54 | * |
| 55 | * The array check is not about permission: get_result_on_prop() indexes |
| 56 | * src() directly, so a non-array source (only reachable if a subclass |
| 57 | * overrides query_source()) must fail here as a catchable |
| 58 | * Preset_Exception rather than a fatal further down. |
