KCAE.SEARCH:4.3 - Read promising material and test the interpretation

Open the source around decisive hits through KCAE.SOURCE. Expand through the condition, exception, definition or example that can alter the proposed contribution. Preserve conflicts instead of choosing the more convenient passage. A preliminary score can prioritize this reading; KCAE.ASSESS turns it into a supported or unresolved contribution.

Actively seek a discriminating countercase when two readings would lead to materially different actions. If a retry paragraph appears to allow unattended resend, inspect restrictions on receiver versions and receipt state. That is targeted challenge, not a demand to read every related publication. If the interpretation survives and the receiving result is available, stop. If it fails, use the discovered condition to formulate the next question.
