## What changed
- Build native voice SDK and runtime artifacts with Bazel for Linux GNU, macOS, and Windows on x64 and ARM64, then configure Cargo jobs to consume them. Keep musl builds in a separate job without these inputs.
- Validate artifact receipts against the target, source commit, and source manifest; verify SDK file hashes and relocate pkg-config metadata. Package the runtime and plugins with nextest archives and restore `CODEX_TEST_VOICE_RUNTIME` when running shards.
- Prepare native Windows voice tools for argument-comment linting and install ARM64 DotSlash on Windows ARM64. Reduce archive disk usage, bound Linux ARM64 build concurrency, and correct the JUnit artifact path.
- Recognize TLS errors wrapped directly in `io::Error`. Make TLS fallback fixtures select the native backend explicitly, allow the MCP test server's non-loopback address, and isolate skill-root tests from ancestor Git markers. Install `git` in remote test containers and filter MCP discovery assertions to POST requests.
## Testing
Add tests for relocated voice inputs, Windows ARM64 import libraries with host-native pkgconf, and rejection of mismatched receipts or corrupt SDK files. Extend untrusted-certificate coverage to an explicitly selected rustls backend.

## Why
HTTPS requests and WebSocket connections on Windows need to authenticate when a proxy rejects `CONNECT` with status `407`.
## What changed
- Retry proxy challenges through the existing Windows authentication helper, using the signed-in user's Negotiate or NTLM credentials. Treat an origin `407` as a normal HTTP response.
- Bridge authenticated tunnels to the HTTP client through destination-specific named pipes, retaining redirect checks and TLS backend fallback without caching those tunnels across destinations.
- Carry explicit CA certificates and client identities into HTTPS proxy TLS configuration, and apply the configured connect timeout when opening authenticated HTTP tunnels.

## Why
Destination restrictions and policy revocation must remain effective during redirects, response body reads, and established WebSocket traffic. Policy denials must also survive error handling so callers do not retry them or report a revoked operation as successful.
## What changed
- Route managed HTTP clients through a shared `RequestBuilder` and policy-aware execution, checking each redirect destination before route resolution and retaining a network permit while consuming response bodies.
- Guard WebSocket connection setup, reads, and writes with revocable permits, including independent wakeups for split readers and writers.
- Preserve `TransportError::Policy` through HTTP, SSE, and realtime error handling, and treat policy denials as non-retryable.
- Keep the supplied network policy in plugin startup HTTP requests and propagate response body failures from backend and plugin requests.
## Testing
Add regression coverage for rejection before connecting, revocation during redirect routing and streamed body reads, split WebSocket revocation, realtime writer error propagation, and revoked plugin upload responses.

## Why
Local MCP requests can fail when the platform TLS backend cannot negotiate a
protocol version with an HTTPS endpoint.
## What changed
- Retry replayable local MCP requests once with rustls after a recognized TLS
protocol-version negotiation failure. Keep certificate, timeout, and unrelated
connection failures on the existing error path.
- Remember successful fallback per HTTPS origin and outbound route, while keeping
the platform TLS backend as the default for other destinations.
- Share the fallback-enabled client across local MCP resolution, CLI login, and
OAuth discovery while preserving remote environment HTTP clients.
## Testing
Added coverage for platform-specific error detection, request replay, cached
fallback reuse and isolation, non-replayable requests, redirects, and remote MCP
client selection.
