+# ban_dict_any — v1
+
+**Why this iteration:** Lifted verbatim from `conductor/code_styleguides/python.md` §17.1 (lines 247-265).
+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.

+### 17.1 Banned: `dict[str, Any]`
+
+```python
+# BANNED:
+def process(event: dict[str, Any]) -> None:
+ if event.get("kind") == "tool_call":
+
+# BANNED:
+flat: dict[str, Any] = project_manager.flat_config(...)
+
+# CORRECT:
+def process(event: CommsLogEntry) -> None:
+ if event.kind == "tool_call":
+
+# CORRECT (boundary only):
+def _parse_wire(raw: str) -> Metadata:
+ return Metadata.from_dict(tomllib.loads(raw))
+```
