What
When a network request fails with an HTTP error in the 400s, Claude Code decides whether the failure is temporary and worth retrying. HTTP status codes are the numbers a web server sends back to say how a request went. Codes in the 400s mean the request was refused. This check used to count only 429 (too many requests) as temporary. It now also counts:
- 408 (request timed out)
- 409 (conflict)
All other 400-range codes are still treated as final.
Why
Claude Code uses this answer to decide whether to record a result as settled when it never actually got one. A timeout or a conflict can now count as temporary, so it is less likely to be locked in as final.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say which request this is or what the saved result is used for.
