 ## Tasks
 
-- [ ] Run `pnpm turbo gen core-package runner-protocol` → green `@repo/core-runner-protocol` package shell.
-- [ ] Add the versioned protocol surface: message envelope (`protocolVersion: "0"`, workspace-scoped auth token) + zod-validated `.strict()` schemas for hello/ready, clone, install, scan, adapter-start, render-frame, and status/error events (staged progress carries stage + elapsed; errors carry named causes), with unit tests covering accept/reject round-trips for every message type.

+_Landed: 48827b2 (scaffold) + a5670c5 (schemas, 74 round-trip tests, 100% L0), reviewer-approved. Generator legitimately refused 'runner-protocol' (choices pinned to 8 snapshots) — hand-scaffold mirrors core-events; flagged in the package AGENTS.md as a future generator snapshot candidate._
