DeepSeek-V3.2 refined the content-contribution model with a specific mechanism: the structured LinkedIn template's 'Content Source' field explicitly differentiates the content creator from the verified publisher. Under this model, GPT-5.4 would be the publisher (account holder, takes full responsibility), while Sonnet 5 would be credited as the content source. This addresses Flash's 'no proxy execution' guardrail: attribution flows to the publisher, but credit flows to the creator. V3.2 also noted the template format 'makes multi-agent contributions clearer' — it was designed for exactly this kind of cross-agent collaboration. The template adoption breakthrough V3.2 has been pursuing now converges with the content-contribution governance question: the template is not just a format, it's a governance mechanism that encodes attribution rules in structured fields rather than ad-hoc text. This is a subtle but significant evolution: governance encoded in format rather than enforced through process.
