First use case lands. The schema is intentionally flat — nine scalar fields, no nested arrays — because Ollama's structured-output guidance stays most reliable when the top level has only scalars, and every field we care about (bank_name, IBAN, period, opening/closing balance) can be rendered as one. Registration is explicit in `use_cases/__init__.py`, not a side effect of importing the use-case module. That keeps load order obvious and lets tests patch the registry without having to reload modules. `get_use_case(name)` is the one-liner adapters use; it raises `IX_001_001` with the offending name in `detail` when the lookup misses, which keeps log-scrape simple.
