The driver retries rate-limit-shaped failures twice with a 65s backoff, but
RATE_LIMIT_SHAPED_RE only matches 429 / rate limit / too many requests /
throttled / CLI timeout. A saturated provider does not always say any of
those: litellm-e2e-pr build 182 turned a green cell red on
status 503: litellm.ServiceUnavailableError: BedrockException -
{"message":"Bedrock is unable to process your request."}
which matched nothing and so was never retried.
Add TRANSIENT_UPSTREAM_SHAPED_RE for 503, 529, "service unavailable",
"overloaded" and Bedrock's "unable to process your request", and have the
retry loop ask is_retryable_shaped (either shape) instead of
is_rate_limit_shaped.
Kept as a second pattern rather than widened into the first on purpose. The
conftest feeds RATE_LIMIT_SHAPED_RE into the rate-limit summary, which the
binary-search helper reads to decide whether to lower a provider's request
rate. A 503 says the provider is out of capacity, not that we are asking too
often, so folding it in there would keep ratcheting our rate down against a
condition our rate never caused.
Retry-loop logging now names which shape fired, so a saturated upstream is
distinguishable from a throttled one in the run output.
Verified against the literal failure text from build 182: is_retryable_shaped
is True while is_rate_limit_shaped stays False.
Note this covers CLI-driven rows only. HTTP-probe rows (tool_search,
count_tokens) have no retry layer at all, so the specific cell that failed in
build 182 is still unprotected -- that is a separate change to http_probe.
