* fix(proxy): name shared-handler errors by the status they answer
handle_exception_on_proxy pinned type=internal_server_error on every
exception it wrapped, so a management route rejecting a caller's own
argument answered {"type":"internal_server_error","code":"400"} and an
SDK branching on the type read its own bad request as a gateway outage.
Derive the type from the status the response actually carries, keeping
a type the exception already names.
* test(proxy): pin a 500 for exceptions whose status is None
* fix(proxy): keep internal_server_error for timeouts and 5xx, redact hosts in shared handler errors
Provider 5xx and timeouts keep internal_server_error so retry loops still retry them,
the shared handler redacts internal hosts from raw exception messages, and /key/list
routes its HTTPException through the shared handler instead of its own copy of the
old label.
* fix(proxy): label shared-handler errors like the chat route, pick the status before the type, redact only gateway failures
* fix(proxy): pass shared-handler error messages through as on main
Redacting timeout and 5xx messages changed what every shared-handler route
returns, which relabeling the error type does not need, so messages go back
to the verbatim text main sends.
* fix(proxy): redact only the status-less failure main never sent
* fix(proxy): answer a generic 500 for a status-less failure and expect auth_error on the /user/new 403
A failure with no status now answers "Internal server error" instead of its own text, since that text can
name a guardrail's private host and pattern redaction misses cluster DNS names and IPv6 addresses. The
/user/new integration test now expects the auth_error type main's route catch-alls give a 403 the proxy raises
* fix(proxy): answer only a 4xx or 5xx carried status and fall back to the route default otherwise
A numeric-string status outside 400 to 599 made /v1/messages, images, rerank and the OpenAI pass-through answer HTTP 200 with an error body or drop the connection, and non-ASCII digits or a 5000-digit string slipped through isdecimal. error_status_code now accepts an int or a three-digit ASCII string in 400 to 599, the range the chat route already enforces
* refactor(proxy): parse a three-digit string status without recursing
