Module analysis 

Analysis layer: enumeration and classification of structure built on top of crate::geom primitives.

Where geom provides the data shapes for tiles, patches, and boundary glues (Rat, Snake, TileSet, GrowingPatch, glue_raw_angles), the analysis layer asks questions about those shapes – enumerating legal glues, classifying vertex configurations, finding fixed points of boundary subsequences, growing patches up to a maximum size.

Modules:

• matchfinder: legal-glue enumeration (MatchFinder, BpSeed) – the operational layer that bridges raw cyclic RC matching (stringmatch::BitParallelMatcher) and geometric validation (Snake / glue / junction checks).
• matchtypes: catalog layer above MatchFinder (MatchTypeIndex) – pre-computes the full match enumeration for a fixed tileset and indexes it for O(1) lookup.
• vertextypes: BFS over open-vertex configurations of a tileset (OpenVertexTypeIndex, Collection).
• neighborhood: corona / phase-2 classification of local tile neighborhoods (NeighborhoodIndex, NtKind, Collection).
• patch_enum: layer-BFS enumeration of all distinct patches of a tileset up to a given size.
• seq_explorer: fixed-point enumeration of cyclic boundary subsequences reachable from a tileset.

Modules

matchfinder

Match enumeration between two tile boundaries.

matchtypes

Catalog of distinct match types for a fixed tileset.

neighborhood

Neighborhood types: catalog of local interfaces between a tile and any legal context patch that could meet it along one contiguous edge run, plus the post-absorption “surrounded tile” states that arise once the central tile’s edges are all consumed.

patch_enum

Multi-tile patch enumeration by incremental boundary glue.

seq_explorer

Enumerate every cyclic boundary subsequence reachable on patches grown from a fixed tileset.
