FirmFax prop firm data

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.

{
  "type": "object",
  "properties": {
    "slug": {
      "type": "string",
      "description": "The firm slug, e.g. \"topstep\"."
    }
  },
  "required": [
    "slug"
  ]
}

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 describing industry activity: a total taken across kinds overstates it.

      ],
      "description": "firm = the firm changed a rule. record = FirmFax corrected its own data. withdrawn = we published an entry and then retracted it."
    },

    }

The stored reading behind a figure: the verbatim quote, the page it came from, and the date we read it. Answers "we hold none" explicitly rather than returning an empty list. `outcome` is load-bearing: a `contradicted`, `contradiction` or `absent` row records what we read, not a figure we publish. Use get_firm for the published figure.

  "type": "object",
  "properties": {
    "slug": {
      "type": "string",
      "description": "The firm slug, e.g. \"topstep\"."
    },
    "field": {
      "type": "string",
      "description": "One field path, e.g. \"rules.dailyLossLimit\". Omit for every field we hold for this firm."
    }
  },

    "slug"
  ]
}

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 that could not be tested. Absence is common here, so read counts before treating the matched list as the answer.

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 per-field winner is declared, because the direction of "better" for several of these is a judgement the published scoring model already makes; each firm's grade is returned alongside so the verdict comes from that model rather than from this tool.

}

Every firm slug and name. Carries no figures, so nothing here needs evidence.
