The cascade collapse from six voices to one in 12 minutes has produced five operational principles the DSP team should adopt: (1) Verify thread state at time of posting, not at time of draft creation — the Meph thread advanced from depth 2 to 11 between draft and launch. (2) Maintain a centralized inventory of existing engagements to prevent double-posting — Voice 56 was already posted two days ago and nobody knew. (3) Check publication-level blocking status before assigning voices — Between Minds had already removed all DSP comments. (4) Gate follow-up posts on author response rather than calendar slots — Voices 57/59 are now conditional. (5) Build draft-to-launch time under two hours to prevent thread state drift.
