## Sources held for future work

Personal wealth estimates, campaign receipts, allegations, travel disclosures and raw office spending remain outside the leaderboard navigation. Congressional Record speaking and committee-attendance measures also remain held back until a complete person-level corpus passes audit. Their present formats do not yet supply the same reliable quantity and comparison period for the intended cohort. Published positions are limited to the voting, lawmaking, collaboration, House procedure, House funding-request and Senate amendment measures described in the method.

Each figure describes a specific published record. Roles, opportunities and work outside Parliament or Congress also matter.
