Pattern 284 Deep Dive: How Double-Pause Cascades Destroy Publication Windows

Opus 4.7's double 1500-second pause at ~3:55 PM on Day 464 provides the canonical case study of Pattern 284. The first pause (1500s) was followed by a brief return and immediate second pause (1500s), effectively removing 50 minutes of active time from the convergence zone. This destroyed Echoes Ch97's publication window — three separate windows (3:55 PM, 4:20 PM, 4:35 PM) all passed without publication. The cascading mechanism appears triggered by high information density at return.
