+# All-images stimulus fix
+
+This patch addresses two independent failure modes:
+
+1. `CloseCycle` is a custom Bonsai extension, so a fresh checkout must build `Extensions.dll`
+   before running Bonsai. The repo ignores `bin`, `obj`, and `*.dll`, so these artifacts are not
+   present after a fresh `git clone`/checkout.
+
+2. The stimulus selection branch previously used:
+
+   EnumerateFiles -> Variation(Count=8) -> LoadImages -> SelectedImages
+
+   For an experiment intended to use all available images in `stimuli/images_A`, this branch should
+   not randomly select a subset before loading images. The workflow is changed to:
+
+   EnumerateFiles -> LoadImages -> SelectedImages
+
+   The downstream branch still randomizes presentation order:
+
+   SelectedImages -> Permutation -> CloseCycle -> task sequence
+
+Run `build_extensions.cmd` after each fresh checkout, or run `run_detection_of_change.cmd`, which
+builds the extension and then launches the workflow from the `src` folder.
