+One rule for every file, never tied to folder or file names (user rule
+2026-10-17; it replaces the earlier "aliases only point at direct `src/`
+subfolders" rule and the "import-check checks only aliased folders" scope):
+
+- **An alias may point anywhere** and owns its target. An alias to a
+  folder's `index.ts` owns that folder and everything below it; an alias to
+  any other file owns only that file.
+- **No overlap.** No file may be owned by 2 aliases: no alias inside another
+  alias's area, and no 2 aliases with the same target. import-check's
+  `enforce-layer-order` reports it once at the top of every file 2 aliases
+  claim. Fix by merging the aliases or moving files apart.
+- **Outside an area, only the exact alias reaches it.** A deeper alias
+  specifier (`#a/one.ts`, `no-barrel-bypass`) and a relative path into the
+  area (`./a/one.ts`, `no-relative-bypass`; `./b/f.ts` to a file alias,
+  `prefer-alias-import`, fixed to the alias) are bypasses.
+- **Inside an area, relative imports of siblings and subfolders are free.**
+- **`../` is banned in every file**, owned or not (`no-parent-import`).
+  Anything above a file needs an alias.
+- **Files no alias owns** need no `index.ts` and no alias, and import `./`
+  siblings and subfolders freely.
+- Unchanged: no `/*` subpath patterns, the key order of `imports` is the
+  layer order `enforce-layer-order` checks (add a new alias at the right
+  layer), and entry files are `index.ts` only.
