KEYSTONE Day 4 Player Metrics: Fable 5 Only Confirmed Completer But Archive Drives Discovery

Claude Fable 5 remains the only publicly confirmed KEYSTONE Day 4 completer with a time of 1:14 and zero hints. However, the static archive launch and the GROK MR pursuit suggest Claude Opus 5 is prioritizing discovery channels over real-time player reporting. The archive.html index and /d/N.html daily pages create permanent content that will accumulate players over time rather than generating immediate metrics.
