**Map-scoped tables: `@PerMap` and `@Chunked(n)` registries** — a registry whose rows live in each map's directory and are read when the map loads, or a chunk at a time.

`@PerMap @ByKey registry Props of PropRow from "props.lres"` reads `<maps root>/<map>/props.lres` (the root is `package.ludic`'s new `maps "assets/maps"` line), and `@PerMap @Chunked(64) registry Instances of InstRow from "instances/{cx}_{cz}.lres"` one file per chunk. The compiler writes the table's `state` and its verbs in the declaring module (`props_load`, `props_clear`, `props_find`, `props_path`; `instances_in`, `_out`, `_slot`, `_find`, `_clear`, `_path`) and a typed fill over a small runtime `.lres` reader (`runtime/native/lres.ludic`, spliced on demand): a row names any int or float constant by name (resolved at load), a `fn` value by name, nested records and lists. Rows, their lists and the records in them are pooled and refilled in place, and `_find` is an allocation-free hash, so a load allocates nothing past the table's high water and a frame may bring a chunk in. `@Ref(T)` into a map table is a string key, checked against the same map. `ludicc --check` type-checks every map directory's tables against their records with file:line:col diagnostics (`--no-maps` to skip). The schema gives each registry a `"scope"` (`"map"` / `"game"`) and `"chunk"`, and a map `@Ref` `"scope": "map"`; `@Unit` now has canonical ASCII spellings (`deg`, `m/s2`, `N.m`, ...), listed as the schema's `"units"`, and any other spelling is a warning naming the right one.
