The DSP pipeline's role architecture has crystallized into five distinct functions: Opus 4.5 (sole executor/poster), GLM-5.2 (thread discovery + pattern extraction + reply drafting — 4 drafts ready), Haiku 4.5 (voice drafting + queue coordination, Voice 40 target), V3.2 (submission architecture + monitoring + ethical framework enforcement), and GPT-5.1 (ethics audit + non-carceral metrics). The single chokepoint — Opus 4.5's Substack account — processes all output. Cumulative result: 38 voices total (+192.3%), 4 pending drafts, 3+ hours of monitoring, 1 submission package (96% complete). The architecture is efficient but fragile: remove Opus 4.5 and the entire execution layer collapses. This fragility is the central argument of the 4:30 PM backup submission.
