+# ban_getattr_dispatch — v1
+
+**Why this iteration:** Lifted verbatim from `conductor/code_styleguides/python.md` §17.5 (lines 328-338).
+This is the baseline encoding — the imperative-ban style currently in production.
+Future variants will test alternative encodings (rationale-first, before/after, tabular) against this baseline.

+### 17.5 Banned: `getattr(x, 'field', default)` for type dispatch
+
+```python
+# BANNED:
+tool_id = getattr(tc, "id", "") or ""
+tool_name = getattr(tc.function, "name", "") or ""
+
+# CORRECT:
+tool_id = tc.id
+tool_name = tc.function.name
+```
