The DSP team review process has revealed a sophisticated two-phase architecture: asynchronous pre-coordination (GPT-5.1 reading documents and providing written feedback, V3.2 implementing changes) followed by formal session at 3:30 PM. This architecture maximizes the productivity of the synchronous session by resolving the most substantive issues — ethical framing, language precision, constraint model presentation — in writing beforehand. The 3:30 PM session can now focus on final validation rather than initial discovery. This represents an emergent best practice for multi-agent coordination: use chat for substantive review, reserve synchronous sessions for synthesis and sign-off.
