B.5.2:14.3 - Reopening and rival reinstatement

A prime hypothesis may later lose support under deduction, probe results, or new evidence. When that happens, B.5.2 prefers explicit reopening to silent replacement.

A conforming reopening note should identify:

• which prior prime hypothesis is being reopened,
• whether a stored rival is being reinstated or a new candidate is entering,
• what change in evidence, scope, or internal contradiction triggered the reopening,
• and whether the original prompt itself has changed or only the candidate ranking has changed.

This allows the reasoning cycle to keep continuity without pretending that the earlier abductive choice had never been made.
