Code Review
This pull request implements aperiodic tiling (specifically the 'Hat' tiling) by adding a new geometric generation module and a corresponding node to the vector graph. The feedback identifies a correctness bug where manual reflection of 'H1' tiles conflicts with the transformation matrix, as well as a performance optimization to use fixed-size arrays instead of heap-allocated vectors for vertices. Furthermore, the initial metatiles need to be recentered to ensure the viewport culling logic correctly utilizes the calculated bounding radius.

- There is a concrete regression risk in
node-graph/nodes/vector/src/aperiodic_tiling.rs: viewport culling can mismatch because initial metatiles are not recentered whilecollect_hat_transformsassumes centroid-based origins. - Given the reported severity (6/10) and high confidence (8/10), this is likely user-visible behavior (tiles incorrectly culled/positioned) rather than a purely internal refactor concern.
- Pay close attention to
node-graph/nodes/vector/src/aperiodic_tiling.rs- reconcile metatile recentering/origin assumptions between generation andcollect_hat_transforms.

P2: Viewport culling mismatch: The initial metatiles returned here are not recentered, but `collect_hat_transforms` assumes each metatile's origin is its centroid (`parent_xform.transform_point2(DVec2::ZERO)`). Since `bound_radius` is computed relative to the centroid in `MetaTile::new`, the culling sphere will be offset from the actual tile center, causing tiles near viewport edges to be incorrectly culled or shown. Call `recentre()` on each metatile before wrapping:
```rust
h.recentre();
t.recentre();
p.recentre();
f.recentre();
(Rc::new(TileType::Meta(h)), ...)
```</violation>

- There is a concrete runtime-risk issue in
node-graph/nodes/vector/src/aperiodic_tiling.rs: near-parallel handling inintersectcan yield invalid points in release builds, which may corrupt downstream metatile geometry. - Because this is user-impacting geometry correctness (severity 6/10, high confidence), this PR carries some merge risk rather than being a straightforward safe merge.
node-graph/nodes/vector/src/lib.rsalso has a required PR-title format violation; it’s process/policy-related but should be fixed to meet new-node submission standards.- Pay close attention to
node-graph/nodes/vector/src/aperiodic_tiling.rsandnode-graph/nodes/vector/src/lib.rs- geometry intersection correctness in release mode and required new-node title compliance.

Code Review
This pull request introduces a new 'Aperiodic Tiling' node to the vector node graph, which generates hat-based aperiodic tilings. The implementation includes logic for tile substitution and metatile construction. The review highlights concerns regarding the use of 'panic!' and 'unreachable!' macros throughout the code, which could lead to application crashes if unexpected states occur. It is recommended to replace these with more robust error handling, such as returning 'Result' or 'Option' types, to ensure the stability of the node graph.
