F.0.1:7.2 - Regression and evolution checks

• RSCR-F01 (Affected edition change). A changed edition or passage reopens only local claims and later uses that relied on the changed content.
• RSCR-F02 (Endpoint change). A changed cell claim or stance triggers recheck of relations and uses that cite that endpoint.
• RSCR-F03 (Composition guard). A relation chain never silently becomes a direct relation or unrestricted substitution.
• RSCR-F04 (Source-cut relevance). Reopen F.1 only when the receiving question or use, a relied source role, known rival, counterexample, or transfer limit changes.
• RSCR-F05 (Historical recovery). An old Context-shaped artifact is recovered only for a current reliance; missing values return as exact unresolved inputs.
