"""interview_planner.py — map Phase-1 interview answers to a CMA primitives skeleton.

Deterministic mapping of the six intake slots (job, trigger, inputs, actions,
definition-of-done, recurrence) to an agent/environment/session/outcome/deployment
skeleton plus suggested v1/v2 deferrals. Implements references/interview-to-config.md.
Stdlib-only; no network calls.

Examples:
  interview_planner.py --job "Triage support email" --trigger schedule \
     --inputs "gmail,memory" --actions "label,draft" --dod "one label + grounded reason" \
     --recurrence daily --model claude-opus-5
  interview_planner.py --answers answers.json --json
  interview_planner.py --sample
