fix(guardrails): resolve decision models in caller team scope (#46085)
* fix(guardrails): resolve decision and judge models in caller team scope * fix(guardrails): scope guardrail model calls to the caller's team only where it owns the deployment Read the team only from the auth object the proxy attached to the request, never from caller JSON, and use it only when the router's route to the guardrail model for that team reaches a deployment a teamless caller cannot. Shared names, aliases, legacy team tags and wildcards keep resolving and billing as before. Decision calls pass the team in litellm_metadata only when it is used, so the logged model group stays intact. Adds integration cells for chat, responses and messages, forged team ids, a team deployment that shares a name with a shared model or wildcard, and billing, plus unit cases for legacy team tags and aliases. * fix(guardrails): route team guardrail calls to the team deployment without charging the team Guardrail calls on a team's own model now go to the deployment the router picks for that team, by its id, with no team on the call. Like every other guardrail call, they write no spend row and add nothing to the team's or the key's spend * fix(guardrails): pin the team deployment only for the judge guardrail, not shadow eval judge calls * fix(guardrails): keep the teamless route when only a team wildcard covers the guardrail model * refactor(guardrails): scope the team model fix to the decision model guardrail only * fix(guardrails): send decision calls on a team's own model with the team, and keep team wildcards out The decision call on a team's own model now carries the caller's team instead of being pinned to a deployment id, so it is charged to that team and goes through the team's normal routing: an access window that reserves the deployment for the team lets the call through, and pre-call checks see the input and skip a deployment too small for it. A team deployment listed under a wildcard public name, such as team_public_model_name openai/*, no longer captures a guardrail model the team never named, whatever model it points at. Adds unit and integration cells for the reserved deployment, mixed context windows under enable_pre_call_checks, a team wildcard name over a fixed model, and the owner team's spend. * fix(guardrails): log the owner team's name on decision calls charged to it The decision call on a team's own model now carries the team alias beside the team id, so the spend row and the Logs page name the team the call was charged to. * fix(decision_model): use the caller's team only for names nothing else serves A team model named like a shared deployment, a shared wildcard or an SDK public name took over the guardrail's decision calls for that team, so a team admin could point a proxy-wide guardrail at their own endpoint. The team is now used only when a caller without a team reaches no model under the name. * refactor(decision_model): drop the team route subset check the served check covers Once nothing serves the name without a team, every deployment a caller without a team can reach is a wildcard, so the subset check only ever rejected an empty team route. Pin team wildcards over a name nothing else serves. * fix(decision_model): use the caller's team only when judge_target finds nothing without a team The served check rebuilt the router's rules and missed a shared wildcard whose provider comes from custom_llm_provider, so a team model under the guardrail's name took over that team's decision calls. Ask judge_target, the same lookup the teamless dispatch makes, instead --------- Co-authored-by: moyai-devin-berriai[bot] <336287033+moyai-devin-berriai[bot]@users.noreply.github.com> Co-authored-by: yucheng-berri <293926326+yucheng-berri@users.noreply.github.com>
