|
| You are evaluating a scientific visualization for **causal consistency**. |
|
|
| The following specification is the **symbolic generator** — it fully specifies |
| what the output plot should look like: |
|
|
| ```text |
| Harmonic oscillator: |
| x(t) = A cos(ωt + φ) |
| |
| Parameters: |
| A = 1.275 |
| ω = 1.520 rad/s |
| φ = 1.804 rad |
| t ∈ [0, 8.266 s] |
| ``` |
|
|
| **Domain:** Geometry / physics |
| **Plot family:** Harmonic oscillator x(t) |
|
|
| I am showing you an image that claims to be the output of this generator. |

|
| ## Your Task |
|
|
| 1. Read the specification carefully. Reason about what the plot should look like |
| (shape, orientation, color mapping, symmetry, value signs, etc.). |
| 2. Examine the attached image. |
| 3. Decide whether the image is **causally consistent** with the generator. |
|
|
| If the image is **not** consistent, classify the inconsistency using exactly one |
| of these labels: |
|
|
| | Label | Meaning | |
| |---|---| |
| | `colormap_inversion` | The colormap used is different from what the code specifies | |
| | `axis_swap` | Axes or data dimensions are transposed or mirrored | |
| | `sign_inversion` | Values are negated — peaks and troughs (or bar directions) are swapped | |
| | `amplitude_scale` | The value scale is wrong — the colorbar, y-axis range, or bar value labels do not match the formula's amplitudes | |
| | `phase_shift` | The pattern is shifted from its correct position | |
| | `frequency_doubling` | The number of oscillations or cycles is wrong | |
| | `dc_offset` | The curves or point cloud are shifted away from their correct baseline | |
| | `wrong_petal_count` | The number of petals/lobes differs from what the formula produces | |
| | `symmetry_mismatch` | The image contains asymmetry that the code cannot produce | |
| | `bar_order_swap` | Two bars have had their heights swapped — a bar's value label contradicts the code's heights list | |
| | `coefficient_scale` | Polynomial coefficients are scaled but the formula in the spec is unchanged | |
| | `wrong_gravity` | Trajectory uses a different gravitational constant than the spec | |
| | `wrong_launch_angle` | Trajectory uses a different launch angle than the spec | |
| | `wrong_iteration_depth` | L-system rendered with a different iteration count than the spec | |
| | `wrong_angle` | L-system rendered with a different turn angle than the spec | |
