Exact command sequence to rerun the patched real-LLM canary and, on success,
perform the Codex → activity-core cutover. Captures the heads-up about CLI
session collision, the host-mode env-var overrides for the worker/API, and the
verification queries for all three evidence surfaces. Frontmatter uses
type: runbook so the consistency checker does not treat it as a workstream.
