Two P0 rows in the reliability coverage registry had no test.
reliability.retry.timeout.succeeds_within_retries gets a new file. The model
group is a pair: an always-timing-out deployment holding all of the group's
shuffle weight, and a healthy backup at weight 0. The weighted pick always opens
on the timing-out one, its first Timeout benches it via an allowed_fails_policy
of TimeoutErrorAllowedFails 0, and the retry falls through to the only
deployment left, so the outcome is a completion plus a reported retry with no
random first pick in the middle.
reliability.fallback.context_window.routes_to_fallback joins the existing
fallbacks spec. It registers a genuinely small-context OpenAI deployment, sends
a prompt past its limit so the provider refuses it on length, and reroutes with
context_window_fallbacks, which is the setting that handles that refusal rather
than plain fallbacks.
Both drive real provider calls through router_settings_override, so no config
change and no second proxy is needed. Reliability & Performance goes 16/36 to
18/36.
