Tin Chi Lo 68c56fe1f6 feat(spend): give the complexity router a savings baseline from its hardest tier
The savings driver only ever worked for the semantic auto-router. It was the one
strategy router that declared a baseline model, so every complexity, quality and
adaptive router fell through to no baseline, compute_autorouter_savings
short-circuited, and autorouter_savings_spend was structurally zero. A deployment
routing exclusively through complexity routers saw $0.00 against real spend, which
reads as "routing saved nothing" rather than "nothing was measured".

A complexity router's tier ladder already names the model an operator would have
had to run to serve the hardest request, so the counterfactual is the priciest
model in the REASONING tier, falling back to the highest-severity tier configured
when REASONING is absent. Deliberately not the priciest model the router can
reach: a pricey model sitting in a low tier is a choice the router made, not a
ceiling it was bounded by, and crediting savings against it would overstate them.

The pricing and resolution both routers need is now one module rather than two
copies. Deployments resolve through model_info.base_model before litellm_params
.model, because on Azure the latter is a deployment name that is absent from the
cost map; without that hop an Azure candidate never prices, and if it was the
priciest the baseline silently drops to the second priciest and understates every
saving.

resolve_baseline can no longer raise. It is read on the routing path while
decorating a request that is about to be served, and a dashboard counterfactual
must not be able to take a live request down; an unresolvable baseline zeroes the
driver instead.

Testing for litellm/

This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.

The point of this is to:

  1. Increase test coverage of litellm/
  2. Make it easy for contributors to add tests for the litellm/ package and easily run tests without needing LLM API keys.
