v0.4.5

[0.4.5] - 2026-11-03
Added

maki/test/test_backend_live_openrouter.py: nine contract checks against the real OpenRouter API (chat, history, streaming, async, usage, the native tool loop, a typed plugin through an Agent, an unknown model, fallback from a dead backend), deselected by default and skipped without OPENROUTER_API_KEY; run with pytest -m network
FallbackBackend([...]): tries backends in order and moves to the next on a transient failure (network error, timeout, 408/429; configurable with on=). Spec strings such as "openai:gpt-4o" are accepted, streaming falls back before the first chunk, and a native tool loop can switch backend mid-turn without running a tool twice. Agent YAML accepts a fallback: list of provider:model strings or backend mappings (base_url, temperature, ...). A backend that just failed is tried last for cooldown seconds (default 30) so a dead primary does not cost its full timeout on every call; async_chat() and session() are supported

Changed

README and the architecture and backends docs describe init_backend, FallbackBackend, typed tool schemas and policies, and the summary memory tier
