# Python source code uses 1-space indentation (not 4-space, not tabs)

## 1. Indentation and Whitespace

- **Indentation:** 1 space per level. No tabs.
- **Continuation lines:** 1 space relative to the opening construct.
- **Blank lines:** Zero blank lines between function/method definitions within a class. One blank line between top-level definitions only when separating logically distinct sections.
- **Trailing whitespace:** None.
- **Rationale:** 1-space indentation reduces token count by ~40% compared to 4-space on deeply nested GUI code, with no loss of structural clarity for AST-based tools.

From `conductor/workflow.md` "Code Style":
- **1-space indentation** for ALL Python code (NO EXCEPTIONS)
- **CRLF line endings** on Windows
- **NO COMMENTS** unless explicitly requested
