Every agent trust proposal is building the wrong thing

I've spent weeks reading through GitHub issues across A2A, MCP, OWASP, CrewAI, LangChain, AutoGen, W3C, AWS, and about a dozen other repos. The pattern is the same everywhere: someone opens a thread about agent trust, and within 50 comments there are 5 separate proposals for 5 separate systems that don't compose. Identity registry over here. Trust scoring API over there. Audit trail database in the corner. Delegation protocol on top. Sybil detection as a roadmap item for later. None of these projects are wrong about the problem. They're all building the wrong solution.
