+; NOTE: a short method-level `#[Test]` is ambiguous between PHPUnit
+; (PHPUnit\Framework\Attributes\Test) and Testo (Testo\Test). The only precise
+; disambiguator is the file's `use` import, but correlating it with the method
+; requires a query rooted at `program`/`namespace` that spans the whole file —
+; such patterns create one in-progress match state per (use-statement × method)
+; pair, which blows past tree-sitter's match limit on real files and silently
+; drops later runnables (gutters vanish from some line downward). So bare
+; `#[Test]` is handled locally by the Testo section instead; PHPUnit here relies
+; on its naming convention (`*Test` class + `test*`/`@test`) and on the
+; fully-qualified `#[\PHPUnit\Framework\Attributes\Test]` below.

+; Testo (https://php-testo.github.io) runnables.
+;
+; Testo detects tests by the `#[Test]` attribute rather than by naming
+; convention:
+;   * a class annotated with a class-level `#[Test]` — every public method
+;     whose return type is `void`/`never` is a test case (other return types
+;     are treated as data providers and skipped);
+;   * any free function annotated with `#[Test]`.
+;
+; A bare method-level `#[Test]` is ambiguous between Testo and PHPUnit, and the
+; only exact disambiguator (the file's `use` import) can only be correlated by a
+; `program`-rooted query that blows past tree-sitter's match limit on real files
+; (dropping later runnables). We therefore match `#[Test]` LOCALLY and treat it
+; as Testo; PHPUnit keeps its naming-convention / fully-qualified detection.
+;
+; Note: abstract classes are not excluded here (tree-sitter queries can't
+; assert the absence of a modifier). Testo ignores them at run time, so at
+; worst a button on an abstract class runs and finds no cases.
