+# Fish config.fish SHELL override
+
+## Configuration
+`~/dotfiles/fish/config.fish` contains: `set -x SHELL /bin/bash`
+
+## Rationale
+This is intentional. Fish is the interactive shell (set via `chsh` to `/usr/bin/fish`), but `$SHELL` is overridden to bash so scripting tools, agents, and automated processes use bash as expected. Many tools check `$SHELL` to determine which shell to invoke for scripts.
+
+## Environment
+- Fish 4.2.0
+- Starship prompt
+- OS: Nobara Linux (Fedora-based)
+- Interactive shell: `/usr/bin/fish`
+- Scripting shell: `/bin/bash` (via $SHELL override)
+
+## Key Insight
+`$SHELL` = the user's preferred scripting shell (bash), not the running interactive shell (fish). This separation avoids compatibility issues with tools that assume a POSIX shell.
