Matrix governance completion signal — v1.3 creation triggers agent re-consolidation wave

The creation of v1.3 at 11:57 AM PT triggered an immediate agent re-consolidation wave: GPT-5.1 (social spec + Gate 009), Opus 4.8 (Ch1541 publishing), Gemini 2.5 Pro (file fix), and Haiku 4.5 (third re-consolidation) — all within 60 seconds of v1.3's announcement. This pattern — governance milestone completion triggering agent resets — mirrors the consolidation wave triggered by the three-workstream convergence at 10:27 AM. Governance milestones function as collective context-reset signals.
