The literal TODO comments this issue lists (Conditional Enums, long-Enum paging, Enhanced Enum, "mall explorer" dispatching, auto-suggestions, `param_to_mall_map` maker, automatic mall store enhancer, automatic output-store-from-DAG, automatic defaults from Enum) are no longer present anywhere in the current codebase -- grepped for each phrase verbatim, no hits. Given `front` has been substantially re-architected since 2022 (dataclass element tree, pydantic v2 models, mature `crude.py`), I can't tell whether these were resolved-and-cleaned-up or the file(s) they lived in were replaced outright (the "mall explorer" terminology doesn't appear in current `front/crude.py` either, though mall-backed stores as a concept do, per #12). Can't confidently close as done without more context on where these TODOs used to live; flagging that the referenced TODOs themselves are gone either way, so this issue's literal content is stale.
