* build(rust): upgrade reqwest to 0.13 and move MCP out of litellm-http
The workspace moves to reqwest 0.13, so litellm-http no longer carries a
second reqwest just for rmcp. The mcp feature, its pool and its proxy
conversion go away, and the gateway hands rmcp a pooled NoRedirect client
that already carries the TLS, proxy and timeout settings
The Client test helpers collapse into for_test, a no-redirect client
without TLS or proxy settings, and wrap_for_test for the few tests that
need a hand-built reqwest client

* fix(http): honor transport settings for Rust WebSockets
The Responses WebSocket connected through tokio-tungstenite with its own
native-roots TLS, so it ignored the configured CA bundle, verify flag,
client certificate, proxies and timeouts. The handshake now goes through
a pooled reqwest client (ClientVariant::WebSocket, HTTP/1.1, no
redirects) and upgrades the response, so it shares the settings every
other outbound request uses
The upgrade response is checked for the Sec-WebSocket-Accept key, the
Upgrade and Connection headers and a subprotocol that was offered

* refactor(http): build outbound requests as reqwest::Request
OutboundRequest was a hand-rolled copy of reqwest::Request. Routes now build
a reqwest::Request directly and RequestSigner reads the body bytes back out
of it, so the signer still covers exactly what is sent. SigV4 signing moves
onto HeaderMap and takes the method, which drops the BTreeMap plumbing and
the header casing table

* refactor(http): make litellm_http::Error the one opaque error
transport::Error and media::Error fold into litellm_http::Error, an
Arc<Repr> newtype whose private variants keep the typed reqwest, io,
rustls and tungstenite causes and own every message. Callers can no
longer build an error with a message of their own. They ask through
dispatched, is_request, status, upstream_response and tls_source
One From<reqwest::Error> now classifies connect, network and timeout
and strips the URL. The WebSocket handshake reports each failed check
as its own variant and owns its connect timeout. OCR drops the media
variants it mirrored, and inference::Error maps a header the signer
computes to Unsupported for every route, not only chat
The error rules move out of AGENTS.md into the rust-error skill, which
also records the decisions behind this design

* docs(rust): split rust-error skill into thin SKILL.md with references
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* refactor(rust-error): render causes once and ask predicates at the boundaries
The four WebSocket handshake variants collapse into Handshake(HandshakeFault), and media download failures no longer answer dispatched() since they happen before the provider call
ErrorDetail in llms and auth-types, the inference error and the OCR error now store their cause in a field named cause with no #[source], so to_string() carries it exactly once and source() is None. Tests that walked the chain now destructure the variant and downcast the cause
The gateway asks is_unsupported() and is_missing_credential() on the inference and OCR errors instead of matching through nested enums, and litellm_auth::Error answers is_missing_credential() for both
The rust-error skill gains axum and pyo3 references, boundaries.md describes the real predicate order and the known divergences, the testing example asserts dispatched() correctly, and shape, classification, conversions, messages-and-causes and recipes agree with the code again
* docs(rust): focus the rust-error gateway page on the error flow and add a rust-gateway skill
The former axum page toured gateway-inference: its status match, the envelope
table, an extractor, the unsupported route and the Sse closure. Those details
belong to the gateway crates and go stale with them. The page is now gateway.md
and follows an error from the provider failure through each From into
IntoResponse, where it is classified once and rendered by surface and framing.
The gateway-structure material moves to a new rust-gateway skill: envelopes per
API surface, extractors and path registration, SSE relay, and the router test
harness.
* test(inference): pin provider URL redaction on every route's transport error
Chat, Messages, Responses and transcription each get a route-level test that
fails if a reqwest error reaches the caller with its URL. The Messages stream
decoder also takes body errors through litellm_http::Error like every other
reqwest error

* docs(rust-error): adopt std source chains and add litellm-error Report
Messages describe their own layer and the cause is the source, boundaries
render the chain once with litellm_error::Report. Corrects skill claims
the audit found stale against the code.

* refactor(rust-error): keep causes as sources across http, auth, secrets, cache and utility crates
Messages describe their own layer and every cause is a typed source,
predicates match exhaustively, and boundaries render with
litellm_error::Report. Media downloads no longer count as dispatched,
Error::upstream bounds the provider body itself, and a forwarded
header SigV4 cannot sign is the caller's fault.

* refactor(rust-error): keep causes as sources in llms and the gateway crates
ErrorDetail loses its string variant, OCR provider variants become data,
host faults stop counting as the caller's, a tunnelled transport error
classifies the same on every stream path, and each gateway crate has one
Error with one status() and extractors that reject in its envelope.

* refactor(rust-error): nest llms errors in inference and ask predicates in route tests
litellm_inference::Error nests litellm_llms::Error instead of mirroring
its variants, host driver faults get their own variant, every predicate
matches exhaustively, and route tests ask predicates instead of matching
transport variants.

* refactor(rust-error): map bridge and gateway-inference errors once and render them with Report
RustUpstreamError has one constructor that always sets headers, argument
checks raise typed errors mapped once, OCR asks upstream_response(), the
Responses stream error event comes from the error type, gateway-inference
loses its string variants, and auth faults classify through one
litellm_auth predicate on every route.

* fix(rust-error): carry OCR provider headers as a HeaderMap and keep outages off the caller
The OCR provider error and get_error_class take reqwest's HeaderMap, the
bridge turns it into Python's (name, value) pairs once. Credential
acquisition and provider SDK failures are no longer the caller's fault,
the UI hides auth and backend causes, and chat keeps a provider answer
as is.

* refactor(rust-error): fix the remaining sweep findings in gateway, llms, auth and cache crates
Auth rejections hide their backend cause on every inference renderer,
path parameters reject in the surface envelope, Textract's unsupported
document and Azure DI's unparseable poll URL get typed variants, the
credential chain exposes its last failure as the source, gateway-mcp
asks predicates over rmcp errors, and the S3 and Azure blob transports
classify through litellm_http::Error.

* refactor(rust-error): fix the remaining sweep findings on the Python side
host-python keeps a native error's chain and returns blocking-pool
cancellation instead of panicking, Vault transport failures convert
through litellm_http::Error so no URL reaches Python, the bridge asks
predicates instead of matching three levels into Vault errors, and the
last string-built PyErrs become typed errors mapped once.

* fix(logger): keep rendered redacted line when template scan flags a key pattern
The blanket REDACTED for a changed msg/color template discarded lines
whose rendered form was already redacted by the same pipeline, e.g.

fall back to REDACTED when the rendered form did not change either,
which is where interpolation can mangle the key pattern the scrub
would otherwise see.
