Audit findings
- Insufficient sourcesNeeds further work
Public secondary summaries omit the boundaries between repeated time leaps and conflict over the exact order of Moeka’s, Yugo’s, and Nae’s deaths or observations.
Before resolving this finding, record every leap and death sequence screen by screen from Chapter 9 of the Taiwan game edition.
- World line unknownNeeds further work
The dark revenge loop can be placed in the 0.523307% context, but each local time leap does not establish a new, verifiable six-digit divergence.
Keep the loop on the same world line and do not invent additional divergence values.
