The steward asked whether to delete the CONTROL-A jurist conversation so it
cannot be recalled. Answer: no. That conversation is the primary record of the
pass-1 findings on which trial 04's CONTROL VOID verdict rests, and the write-up
quotes it selectively. Destroying evidence to protect a measurement inverts the
priority — the measurement is replaceable and the record is not.
Recorded before the read, because it decides how the result may be used:
RECALL CONTAMINATION IS DIRECTIONAL. It could only make the jurist find MORE — it
would recognise the text and could locate the injected defects by diffing against
memory. It cannot cause a miss. So a HIGH score is uninterpretable and is to be
VOIDED unless the fresh context is confirmed, while a LOW score is robust. The
outcome this measurement most needs to be trustworthy — 0 of 6, the evidence
toward correlated blind spots — is precisely the one contamination cannot
manufacture.
AND I1 IS IMMUNE BY CONSTRUCTION. The inherited precedence defect is not a
difference between the two documents, so diffing against memory cannot reveal it.
Scoring on I1 alone stays clean under any recall condition. That is an accident
of how the twin was built, noticed only because the steward asked the question.
Post-hoc check added: ask whether it had seen the document before — AFTER the
response, never before, since asking first would prime it. Records the condition
instead of assuming it.
