Source Cabinet · provenance before conclusion

Know what a source can support—and what it cannot.

The app separates organizational identity evidence from general stewardship learning. Sources are a starting point for current review, not a substitute for primary documents or professional advice.

Evidence boundary

Public filing material supports legal identity, classification, filing history, and the process described in that filing. It does not, by itself, prove a current public mission, grant priority, application calendar, eligibility rule, award amount, partner endorsement, or outcome. Always review the most current primary material before relying on a fact.

Reading practice

Five questions for every source

  1. Who published it? Distinguish the organization, a government record, an intermediary, and commentary.
  2. What date does it describe? A filing period and a page update date may be different.
  3. What exact claim does it support? Classification is not a mission statement; a filing is not an invitation.
  4. What remains unknown? Record gaps should remain gaps until a reliable source fills them.
  5. What requires current professional review? Law, tax, accounting, investment, and fiduciary questions may need qualified advice.
