|---|---|---|
compare_firms | Two firms side by side. Reports each figure with its evidence state and whether the pair is comparable at all: a field neither firm records is not a tie, and a field only one records is not a win. No | typed |
list_firms | Every firm slug and name. Carries no figures, so nothing here needs evidence. | typed |
get_firm | One prop trading firm. Every figure states whether we hold evidence for it, and a firm whose score range spans more than one band carries no letter grade at all. | typed |
get_rule_changes | The dated record of what changed, newest first. Every entry states its KIND, and most of this tape is FirmFax correcting its own data rather than a firm changing its rules. Read counts before describi | typed |

find_firms | Firms matching every criterion given. A firm whose record does not carry a criterion is never counted as a match and never silently dropped: it is returned separately under unknown, with the field tha | typed |
