display_name: "Budget Router — Budgeted API Reliability RL Environment"
description: >
  A POMDP environment where an agent routes requests across three providers
  under budget, SLA, and reliability constraints. Providers degrade non-stationarily;
  the agent must detect degradation from windowed observations and adapt routing.
  Four difficulty tiers: easy (stable), medium (A degrades after step 5),
  hard (immediate degradation, tight budget), hard_multi (cascade failure A+B).
  Designed for post-training agentic reliability agents.
