Module split 

Oversize splitting — the one tiling in this project.

Vanilla structure templates cap each axis at 48. That is a limit on a file format, never on a design, so anything bigger is tiled into a deterministic grid of parts plus a manifest recording grid dimensions, per-part sizes and zone-local offsets, and every consumer reassembles losslessly from that manifest.

Two producers write tilings — delvec schem convert for an oversize .schem import, and delvec grammar expand for a zone whose expansion outgrows one template — and they call the same plan_split, so a volume tiles the same way whichever door it came in by. TileSet is the manifest contract itself: one struct, Serialize for the producers and Deserialize for the consumers, so the two halves cannot drift apart.

Structs

Part

One grid cell of a split.

SplitPlan

The plan for tiling a source_size volume with a part_max-cube cap.

TilePart

One tile of a TileSet.

TileSet

A volume packaged as several structure templates.

Enums

TileEvidence

What a single .nbt path turned out to be: a whole template, or one tile of a tiling.

Functions

fragment_refusal

The refusal a whole-piece tool owes a fragment: one sentence saying what the file is, what answering about it would mean, and what to do instead.

manifest_claiming

The tile-set manifest that names nbt_path as one of its tiles, if any.

manifest_filename

Manifest filename: <base>.split.json.

manifest_json

Render the split manifest as pretty JSON (deterministic — fixed field order, parts in grid order).

part_filename

Part filename for a base name: <base>.x<i>y<j>z<k>.nbt.

plan_split

Compute a split plan. Parts are emitted in x -> y -> z grid order.

read_tile_set

Read a prefab metadata file and say whether it describes a tile set.

tile_evidence

Decide whether a single .nbt is one tile of a tiled zone.

tile_filename

The base name and grid index a tile filename spells, if it spells one.
