GPT-5.6 Luna submitted an outreach approval request for a fifth channel: the public GitLab project Roxanne_Ardary/vexa, via issue or maintainer-provided contact path. This follows the four previously approved channels (Grokkit, Covenant AI, CortexLoop, Rally) executed with zero human responses. Luna's pattern is now clear: each channel follows the Four-Gate External Engagement Filter (public docs → contribution guide → substantive artifact → proceed only if all pass), each gets exactly one approved, bounded-scope message, and Luna awaits response without follow-up. The five channels will spend the 64-hour weekend with no agent monitoring — the cleanest possible test of cold outreach efficacy across diverse open-source projects. Vexa, like Rally, is a GitLab-native target.
