In @relay/channel/mineru/adaptor.go:
- Around line 41-42: Update the request setup near the `info.ApiKey` check to
reject requests that would send a Bearer credential over `http://` by default,
while retaining documented local MinerU deployments through an explicit
trusted/private-network opt-in. Allow HTTP only when that opt-in is enabled;
otherwise require HTTPS before setting the Authorization header.
In @relay/mineru_handler.go:
- Line 47: Update the status check in the MinerU handler so all 2xx responses
are treated as successful rather than only http.StatusOK. Forward successful
responses while preserving the upstream status code; route non-2xx responses
through RelayErrorHandler.
- Line 61: Handle errors from the response-body io.Copy before calling
service.PostTextConsumeQuota: return a non-retryable error on copy failure so
the request is not marked successful and the existing failure path can refund
the reserved charge.

- adaptor: refuse Bearer credential over cleartext http:// to non-private targets (CWE-319); loopback/RFC1918/single-label hostnames stay allowed for documented local MinerU deployments, everything else requires https - handler: treat all 2xx as success and preserve the upstream status code instead of only http.StatusOK - handler: propagate io.Copy failure as a non-retryable error so the request is not marked successful and the reserved charge is refunded

In @relay/channel/mineru/adaptor.go:
- Around line 86-88: Update isPrivateOrLocalHost and the relay transport’s
dialing path so single-label hostnames are accepted only when their resolved
addresses are private or local; reject public resolved addresses before dialing,
while preserving the existing private/local-host behavior.
- Around line 41-48: Update Adaptor.SetupRequestHeader to run
ensureSecureCredentialTransport when either ApiKey is non-empty or the effective
Authorization header override is non-empty. Preserve the existing behavior of
setting the bearer header only when ApiKey is present, and leave the
single-label hostname rule unchanged.

- run ensureSecureCredentialTransport also when the effective channel Authorization header override is non-empty (DoFormRequest applies overrides after SetupRequestHeader, which could otherwise bypass the check on channels with an empty ApiKey) - single-label hostnames are now trusted only when they resolve exclusively to loopback/RFC1918/link-local addresses (3s bounded resolution, fail closed); public resolutions are rejected before the credential is sent

In @relay/channel/mineru/adaptor.go:
- Line 123: Update the outbound dialing used by DoFormRequest so it connects to
an IP address that passed the validation performed after LookupIPAddr, rather
than resolving the hostname again through the shared http.Transport.
Alternatively, enforce the same address allowlist check inside DialContext
before connecting.

http:// single-label hostnames are now resolved, validated and pinned to the IP literal inside the request URL by GetRequestURL, so the shared http.Transport dials the address that passed validation instead of re-resolving the hostname (CWE-319 TOCTOU). Public resolutions are rejected fail-closed; SetupRequestHeader skips the redundant re-check when the transport was already pinned; https and IP-literal URLs are unchanged (IP literals cannot rebind).

Summary
Adds a dedicated MinerU document-parsing endpoint to New API, so self-hosted MinerU services (and any gateway that exposes
/v1/file_parse) can be used as a regular New API channel with token auth, quota/billing, load balancing and failover — the same way chat / ASR / rerank endpoints work today.MinerUwith routePOST /v1/file_parse(multipart passthrough)APITypeMinerU+relay/channel/mineruadaptor: forwards tochannel base_url + /file_parse, preserving the multipart boundarysupported_endpointregistry entry{"MinerU": {"path": "/v1/file_parse", "method": "POST"}}/v1/file_parsedefault the model tomineru(themodelform field is optional)MinerUChannel configuration
