Session shape
Rounded median shapes from recent Pi agent sessions.
Warm-request cache reuse
Effective token reuse combines partial hits and occasional complete misses.

The first request starts cold unless marked otherwise. Output is billed separately from context growth because reasoning tokens are not always retained. This remains a directional estimate: providers differ in eligibility, rounding, and retention.
