WalkthroughSynchronous and asynchronous response processing now enforces configured retry limits and preserves zero-valued ChangesRate-limit retries
Priority: ➖ Normal Estimated code review effort: 2 (Simple) | ~10 minutes Change: Bug fix Merge Risk: 🔵 Low · up to The change correctly stops repeated 429 retries at the configured limit and honors a zero Retry-After delay. An unusually large Retry-After value could still make a request wait a very long time. This is an edge case worth a maximum-wait cap but not a blocker. 🚥 Pre-merge checks | ❌ 1❌ Failed checks (1 warning)

- Around line 338-344: Bound HTTP-date delays in parse_retry_after to a maximum
wait, using the configured fallback delay when a parsed date exceeds that bound;
ensure both synchronous and asynchronous response paths use the bounded result.

A Retry-After HTTP-date far in the future could make the client sleep for days. Delays above MAX_RETRY_AFTER_MS (60 s) now fall back to the configured delay, and negative values are treated as 0.

Added a 60s cap: longer Retry-After values (including far-future HTTP-dates) use the configured delay. |

Description
Repeated 429 responses currently bypass max_retries, so an enabled retry policy can loop indefinitely. Both sync and async requests now stop after the configured retry budget and raise the last APIError.
The same rate-limit path also reads Retry-After from response_headers, while APIError stores it in http_headers. Read the actual headers, preserve a zero-second delay, and compare HTTP dates against timezone-aware UTC.

Additional Information
All 62 unittest tests pass. The added regressions demonstrate seven failing cases before the fix, including both client modes with zero/two retries and Retry-After parsing. Existing successful-retry tests remain passing. git diff --check passes.
