Called for each locally-enumerated entity with its parent information. Faces have exactly 2 parents; edges can have N >= 2.

Parameters

parents	All parent indices (local-appended) of this entity. [0, nLocalParents) = owned, [nLocal, nTotal) = ghost.

Logical entity roles in the mesh. Topological depth depends on the mesh dimension (2D or 3D).

In 3D: Cell=3, Face=2, Edge=1, Node=0. In 2D: Cell=2, Face=1, Edge=1 (==Face), Node=0. Bnd shares Face's depth but is stored separately (zone-labeled subset).

Parameters

ind_offset Absolute index of the first row in this sub-graph. For a full graph this is 0 and no filtering occurs.

Build CSR with 0-based local indices: subtract ind_offset and skip entries outside [ind_offset, ind_offset + nCell) (cross-sub-graph edges).

Reserved skeleton for parallel topology interpolation.

This commented-out method is preserved as a placeholder for a future generic topology management API. Currently, mesh topology (cell2face, face2cell, etc.) is constructed serially and distributed. However, a parallel interpolation capability may be needed for:

Dynamic mesh adaptation (refinement/coarsening)
Load balancing with topology migration
Multi-physics coupling with different mesh partitions

If implementing parallel topology construction, this skeleton provides the basic structure for building face-based adjacencies from cell2node without requiring a serial global mesh on rank 0.

	)

Partition a sub-graph into nParts and optionally apply RCM reordering within each part.

Partition a sub-graph and optionally RCM-reorder within each partition.

This function operates on the sub-range [mat_begin, mat_end), which represents n_elem rows of an adjacency graph. Adjacency entries use absolute indices (offset by ind_offset), i.e., cell i's neighbors are stored as (ind_offset + local_index).

When called for second-level (inner) partitioning, the sub-range's adjacency rows may contain cross-sub-graph references pointing outside [ind_offset, ind_offset + n_elem). These arise because the first-level partitioning reindexed the full graph, and boundary cells retain edges to cells in other first-level partitions. Two problems follow:

Metis and the partition-adjacency builder require a self-contained local graph; cross-sub-graph edges must be excluded from these operations.
When cells within this sub-range are permuted, all references to them – including those in other sub-ranges' rows – must be updated to maintain the bidirectional graph invariant. The optional full_mat_begin / full_n_elem parameters provide access to the full graph for this cross-sub-graph fixup.

The RCM section trims cross-sub-partition edges before reordering (each sub-partition only needs internal connectivity for bandwidth reduction). The RCM reindex uses (ind_offset + local_offset) as the base for correct absolute index arithmetic.

Parameters

full_mat_begin	Iterator to the start of the full graph (for cross-sub-graph reference updates). Pass default (empty) when this sub-range IS the full graph (first-level call).
full_n_elem	Total number of rows in the full graph. 0 means no cross-sub-graph fixup is needed.

When used for second-level (inner) partitioning, pass full_mat_begin / full_n_elem so that cross-sub-graph references in the full graph are updated after permutation. See implementation in SerialAdjReordering.cpp for detailed documentation.

PartitionSerialAdj_Metis now handles the filtering and rebasing internally via its ind_offset parameter.

Build partition-level adjacency (which partitions neighbor which). Only intra-sub-graph edges matter for partition adjacency.

Permute rows according to partition assignment; build i_old2new mapping.

Remap in-range references within the permuted sub-range rows. Cross-sub-graph references (outside [ind_offset, ind_offset + n_elem)) are left unchanged here; they point to cells not touched by this permutation.

Update cross-sub-graph references: rows OUTSIDE [mat_begin, mat_end) may contain edges pointing into this sub-range with pre-permutation indices. Walk the full graph and apply i_old2new to any such references.

Per-partition RCM reordering. Cross-sub-partition edges are trimmed before RCM since bandwidth reduction only considers intra-partition connectivity. The reindex step uses (ind_offset + local_offset) as the absolute base.

Trim: remove edges outside [ind_offset + local_offset, ind_offset + local_offset + local_nelem)
