"""Keiro gateway infrastructure (canonical home, moved from ember.gateway).

This package provides shared infrastructure for the gateway: middleware,
limiters, stores, providers, settings, and runtime bootstrap. The HTTP
application factory and route handlers live in ``keiro.gateway.http``.

Modules:
- admission: deterministic policy admission and RBC issuance
- rbc: Request Budget Certificate signing/verification (HS256-like)
- stores: in-memory and Postgres billing/idempotency stores
- router: simple router-lite scoring with session affinity
- providers: provider adapters for upstream LLM APIs
- middleware: auth, rate limiting, TPM, concurrency, error handling
