PSD.10:4.6 - Return the strongest supported claim and no stronger

A short return states:

  • what claim about which alternatives is supported, for which configuration and horizon;
  • its uncertainty representation, source limits, and dependencies;
  • what different answer could change the comparison, admissibility, or receiving use;
  • the exact unanswered question or blocker; and
  • what source, observation, candidate, value, or configuration change would reopen the account.

Return “unchanged within the tested bounds” only when those bounds cannot alter the stated result. Return a conditional or narrowed claim when support covers only part of the use. If a required protected-condition premise is unsupported, preserve the direct domain stop rather than compensating with confidence elsewhere.

Recognition may begin with one unexplained estimate. Consequential reliance requires the evidence and assurance demanded by the direct practice, including its independent checks when applicable. This pattern supplies no universal evidence score or acceptable uncertainty threshold.

When a relied-on source actually changes, revalidate the affected use. Use G.11 for a currentness question and A.10.1 when the changed claim must be traced through several actual uses. Do not discard unrelated claims merely because they share a source file.
