• Add Rust action contract coverage for every agentOS actor-plugin dispatcher arm.
• Cross-check Rust contract fixtures against TypeScript action/event/DTO declarations.
• Generate the AgentOS actor action type surface from the Rust contract table via build.rs into an ignored local TS file.
• Add a simple always-on package-level actor smoke test and fix actorOptions forwarding plus WriteFileResult typing drift.
• Let the sidecar resolver find repo target/{release,debug} builds like the actor plugin resolver.
