 ## Tasks
 
-- [ ] Scaffold `apps/runner`: WS server speaking `@repo/core-runner-protocol` (every message zod-parsed), hello/ready handshake gated on the workspace-scoped auth token, status/error event emission; integration test spawns the real runner and completes the handshake over real WS.

-- [ ] Add the clone stage: git clone of the requested repo with the PAT delivered via an ephemeral credential helper (spec §6 verbatim — never in URLs, argv, logs, or `.git/config`), staged progress events; integration test clones the `git daemon`-served `vite-kitchen`, asserts credential-leak absence (grep argv/logs/`.git/config`), and asserts named failure events for bad URL / bad token.

+_Landed: b090e26 + 750ab44 + ec7bf94 (cherry-picks), two independent adversarial reviews approved — credential-leak surface airtight (blank-then-veect helper, PAT via child env only, proven by unit builder + integration grep of logs/.git/config/.git surface + spawn-suite whole-child-output grep). Auth proven via a Basic-auth dumb-HTTP git fixture (real 401→helper→retry, asserts exact x-access-token:PAT). 98 tests, 96.6% coverage. Honest boundary: real smart-HTTP/GitHub deferred to later PRDs (documented in apps/runner/AGENTS.md)._
