# 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))
```
