Documents each pick_instance_* function from cache_aware_proxy.py in pseudocode so the policy semantics can be cited without re-reading implementation details. Covers lmetric (main baseline), load_only (no cache / no affinity control), sticky (hard affinity control), unified (gated affinity + LMetric fallback), and capped (lmetric on a per-session turn-capped trace). Includes a decision matrix that maps each policy to whether it uses session affinity, cache awareness, load awareness, and overload break, plus a one-liner per control explaining what comparison isolates which factor.
