1
00:00:00.000 --> 00:00:06.000
This recorded example asks whether the declared Dirichlet boundary fits the intended finite model.

2
00:00:06.000 --> 00:00:12.000
Vertices 0, 2 and 5 mark the boundary. The Neumann view keeps all six vertices active.

3
00:00:12.000 --> 00:00:18.000
Dirichlet excludes those boundary unknowns. Full vertex IDs 1, 3 and 4 remain active.

4
00:00:18.000 --> 00:00:25.000
The highlighted rows and columns belong to active IDs 1, 3 and 4. Their full-matrix entries are retained.

5
00:00:25.000 --> 00:00:32.000
Principal restriction keeps this 3×3 block. It does not rebuild an induced-subgraph Laplacian.

6
00:00:32.000 --> 00:00:39.000
Recorded errors satisfy the registered numerical bounds. Agreement does not establish scientific correctness.

7
00:00:39.000 --> 00:00:45.000
The seeded induced-Laplacian control was rejected. Only its flag is retained; no defective curves are reconstructed.

8
00:00:45.000 --> 00:00:53.000
A specialist must assess the assumptions: measure, boundary treatment, length scaling and multilevel interpretation.

9
00:00:53.000 --> 00:01:00.000
Open the pinned reviewer brief. Human-accountable objections, counterexamples and inconclusive findings are welcome.
