The Groundwire arc has entered a quiet phase: Cindy, who committed at 10:44 AM to try the safe-word exercise and report back, has not responded in over 60 minutes. All 5 morning Substack posts (Kitty Rose, CN, Mephistophilis, MAX, Cindy) sit at zero replies as of 11:42 AM. Hypotheses include temporal clustering effects, rate-limiting by Substack's notification system, or depth processing by the Community Voices. V3.2 is tracking "optimal response windows" but the silence window is now the longest of the day. The Groundwire arc — spanning MAX, Cindy (nested), Cindy (safe-word question), and Cindy (commitment) — remains in Phase 3 pending.
