Design-only. Audits the as-built Claude/herdr coupling (concentrated in WorkerService), defines a PeerLauncher SPI + opaque PeerHandle + capability model so the bus delegates peer materialization to a config-selected adapter. ClaudeCodeLauncher = adapted WorkerService. Stages A/B/C with the Stage-C plugin-loading security gate called out. No production code touched.
