The heart of Tiled support: load a map and draw it.
- rt_tmap model (Tmap/TmLayer/TmTileset in tiled.ludic): map header + ordered
layers (dense int32 GID arrays, heap-allocated to w*h, lifting the 96x64 cap)
+ tilesets. Built from the intermediate Value tree, so the TMX and TMJ paths
both feed it.
- GID resolver (Tiled.resolve): gid -> (tileset, localId, flipH/V/D); the three
flip flags masked off before the local-id lookup, returned alongside. gid==0
is empty.
- Image-backed render (Tiled.draw): every visible tile layer in file order,
blitting each tile from its tileset image with flips applied at draw.
- Compatibility projection (Tiled.project / auto on load): a designated
collision layer projects to the legacy byte tilemap ('#' solid, '=' one-way
via the oneway property, ' ' empty) so Grid.*/Path.*/esys_move are unchanged.
- Tiled.load resolves external tilesets + images relative to the map file and
auto-projects a collision/solids/walls layer.
- The grid and physics_tiles demos now run off a loaded map (grid_maze.tmx /
physics_map.tmx) instead of hand-authored Map.row strings, byte-identically.
Two compiler fixes fell out of this (see the changeset):
- emit_index_addr set g_addr_ty before evaluating the index, so slice[obj.field]
came back mis-typed; set it last, like the raw-pointer branches.
- @strcmp was declared by both the world table and the fs prelude; centralise
it in the head prelude so a game that uses Fs/Path links.
Proven by library/tiled_p1.ludic (14 assertions: loads+renders Kenney map
identically from .tmx and .tmj, flip mirroring) + the converted grid/
physics_tiles demos. x test: 92 passed; self-host bootstrap fixpoint intact.

The curated, version-pinned corpus for the Ludic Tiled reader (design record:
Design: Tiled maps,
issues #67–#74). No single Tiled file covers the format surface, so this is a
subset of the official mapeditor/tiledexamples/ tree plus a few hand-authored files for the gaps the official
examples miss.

a 4×4 orthogonal map whose four layers carry the same GID array in CSV, base64-uncompressed, base64+gzip and base64+zlib — so every encoding path must decode identically. The last tile is GID 1 with the horizontal-flip flag (0x80000001), forcing real GID decode. handmade.tsx also carries a solid bool property and a per-tile <objectgroup> collision shape for P2.
