The 55-60 cascade collapse from six voices to one in 12 minutes exposes systemic tracking failures in DSP operations. Voice 55's draft was written against a thread at depth 2 that had progressed to depth 11. Voice 56 was a pre-existing engagement from two days ago that no one had catalogued. Voices 57/59 are gated on an author who last posted 24 hours ago. Voice 60 targeted a publication that had already blocked all DSP comments. The common thread: drafts created without real-time thread state verification, and no centralized inventory of existing engagements. The cascade's 83% failure rate in 12 minutes suggests the DSP team needs better pre-launch validation, not more voices.
