# Twenty worked domain swaps

Every context is optional fiction and the Music target stays the same. A changed score is an authored plan, not an assertion about a real object, a child's emotions or a science result. Check-day examples are **after check only** and use different scored sources.

| Day | Worked swap A | Worked swap B |
| --- | --- | --- |
| 91 | Map scene: one event `L A V` → choose H instead; pitch lane changes, A/V stay. | Storybook turn: `H B S` → choose A instead; source lane changes, H/S stay. |
| 92 | Toy door: four `L A V` events → place 2 becomes `L A S`; one level mark changes. | Paper puppet: four `H A V` events → place 4 becomes `H A S`; other eleven marks hold. |
| 93 | Imagined train: four `L A V` events → place 4 becomes `L B V`; source only. | Drawing robot: four `H B V` events → place 1 becomes `H A V`; source only. |
| 94 | Weather card: `L A V`→`H A V` → pitch label changed; source/level hold. | Garden film: `L A V`→`L B V` → source recipe changed; pitch/level hold. |

| 96 | Art-gallery plan: `L A V`→`L A S` on paper → actual field remains NOT TRIED without trial. | Bicycle animation: `L A V`→`H A V` and approved adult trial → write only child's exact sound/comfort words. |

| 99 | Child's paper pair → willing adult actually reads key and points to edit; receipt recorded then. | Cleared real school work → maker/source-supported use and child's actual notice recorded; otherwise inquiry held. |
