Plan Generator

When Codex should use it

• After onboarding completion or goal updates.
• When the user requests a new plan or calendar export.

Invocation guidance

1. Load shared contracts from _index/references/contracts.md.
2. Inputs must include UserProfile, TrainingHistory, and optional RecentRunTelemetry[].
3. Enforce rest distribution and load caps from deterministic rules (v0/lib/plan-complexity-engine.ts, v0/lib/periodization.ts).
4. Return JSON matching Plan + rationale.
