-# Document indexer test fixture
-
-A small line-oriented test language (`.idx`), unrelated to any framework:
-`def key`, `ref key`, `alias prefix# target#` and `symbols prefix`.
-References also produce gutter markers. `symbols` uses host-supplied UTF-16
-syntax ranges. `invalid key` deliberately returns an out-of-bounds range.
-
-Used by `cargo test -p ide-host --test plugin_indexing` to exercise the optional
-WIT export, lifecycle invalidation, permissions, per-window isolation, candidate
-selection and warm memory-only lookups. It is not a marketplace plugin.
