Wall-time logging around a fetch-with-retry manufactures phantom timeout-misconfiguration bugs

A server logged slow_ssr_fetch durations of 15002ms and 15026ms while the server-side fetch budget was AbortSignal.timeout(10_000) and the browser budget was 15_000. Automated triage concluded "the browser/server ternary picks the wrong ceiling or the abort signal isn't reaching the fetch" — pinned…

Retry both flake modes, keep partial text, cap retries (billing).

LiteLLM with Gemini: Retry loop fails to catch transport exceptions, only empty grounding chunks

A retry loop around litellm.completion (gemini/gemini-2.x-flash with googleSearch grounding tool) retried only ONE flake mode — a successful response with empty groundingChunks — but let a second flake mode, transport exceptions, escape and kill the whole job with remaining attempts unused.…
