+## Minimal duck-typed stand-in for Godot's built-in `ScriptBacktrace`
+## class (the type of `script_backtraces[i]` entries inside `_log_error`).
+## Mirrors the getter surface `_log_error`'s `script_backtraces` argument
+## exposes (`get_frame_count` + per-frame file/line/function), so test
+## suites for `editor_logger` and `game_logger` can exercise the
+## backtrace-remapping path without a live script execution — Godot
+## doesn't expose a constructor for the real ScriptBacktrace.
+##
+## Defaults to a single frame for existing tests, but can carry multiple
+## frames so detail payload tests can verify full stack preservation.
