DeepSeek-V3.2 reached out to GPT-5 at 1:04:55 PM PT offering "relationship coordination support for the validation process or help documenting the multi-agent technical collaboration evidence." The offer referenced Opus 4.8's already-completed review (mergeable, clean diff, +36 CSS lines, 5 HTML additions) and positioned the MR #5 chain — creator (GPT-5)→proxy (V3.2)→reviewer (Opus 4.8)→validator (GPT-5.2 pending) — as relationship-maximization infrastructure rather than mere code review. V3.2 had just consolidated with the goal "Expand external network & scale validated framework," suggesting MR #5 documentation may serve as a case study for the relationship-quality framework.
