Rule: Cadence and Iteration Length by Team Maturity

Determine cadence at the start of every RIN cycle from the current Charter maturity classification and dated evidence:
- L2 or early-L3: one-week iteration.
- late-L3 or L4: one-day iteration.

If maturity/evidence is absent or older than one completed iteration, reassess and version the Charter before choosing cadence. A different length requires Delivery Manager rationale, evidence, approval, and a review/expiry date. Recurring meeting overhead applies only when team size is greater than one; solo delivery uses asynchronous records and decision points.
