Note

Medium Risk
Modifies core request URL construction and retry backoff behavior, which can affect all API calls if query merging or retry timing changes are incorrect. Remaining changes are largely CI/test/package maintenance and dependency pinning.

Overview
Bumps the SDK to 0.57.1 and updates release metadata (CHANGELOG.md, manifest, OpenAPI stats).

Fixes the client’s URL building to preserve query parameters already present in the request path by merging url.searchParams with defaultQuery and per-request query params in src/client.ts.

CI/test reliability updates: artifact upload in ci.yml now skips stl/* branches, scripts/mock pre-installs Prism and adds a 30s startup timeout with better logging, and file upload tests use simpler placeholder content. Also pins minimatch via overrides/resolutions and updates yarn.lock accordingly.

Malformed retry-after header bypasses backoff due to NaN

Medium Severity

When the retry-after header contains a string that is neither a valid number nor a valid date (e.g., a malformed value), Date.parse() returns NaN, making timeoutMillis equal to NaN. The new guard timeoutMillis === undefined evaluates to false for NaN, so the default backoff is never applied and sleep(NaN) resolves immediately (since setTimeout treats NaN as 0). The old guard caught this because NaN is falsy. This could cause aggressive retry storms against a server sending malformed headers.
