"""Persona orientation via kaizen-agentic (ADR-005 prepare step).

The ADR-005 contract for a scheduled run is `kaizen-agentic schedule
prepare <agent>` executed against the target repo: it bundles the agent
prompt, project memory, metrics summary, and repo pointers from local
`.kaizen/` state — offline-safe, no hub required. The worker treats the
bundle as orientation text prepended to the task prompt.

Falls back to an empty bundle when the CLI or the repo's schedule state is
absent, so a task can still run persona-less (logged in run metadata).
