 `anthropic_api` and `pi_rpc` require explicit `llm.model_map` entries for every
 tier an agent asks for; an unmapped tier fails the run and names the entry to
 add. A built-in mapping is a floor, not a recommendation: override the tier in
-`llm.model_map` when a stage deserves a stronger model than its tier implies.

+`claude_cli` maps `small` and `medium` to the same model deliberately. A tier is
+what an agent asks for, and the built-in is what this CLI is willing to run a
+review on; nothing obliges the two smallest tiers to differ when the cheaper
+model is not one a review should rest on. An operator who wants a genuinely
+smaller model for `small` names it in `llm.model_map`.
 
 For Anthropic subscription profiles, `adapter: claude_cli` runs Claude Code
