## What changed
- Wait for the authenticated Noise handshake before sending the JSON-RPC
`initialize` request.
- Share the configured initialization timeout across the handshake and RPC,
while preserving the configured duration in timeout diagnostics.
- Record the handshake and initialization RPC as child spans of the existing
initialization span, and terminate transport tasks when handshake readiness
fails.
## Testing
- Cover stalled handshake timeouts and cleanup of the underlying WebSocket.
- Cover timeout reporting after the handshake has consumed part of the budget.

## Why
Planned executor replacement needs a fresh session without waiting for the old
session's transient-disconnect recovery to finish.
## What changed
- Add `Environment::refresh_connection` for remote Noise registry-backed
environments. It performs a fresh registry lookup, reuses a healthy session
when the executor identity is unchanged, and connects to a replacement when
it has changed.
- Retire superseded sessions and connection attempts so they cannot publish
stale state, accept late RPC results, or replay outstanding work.
- Preserve the existing environment and filesystem handles while replacing the
underlying client, and require a live status probe before refresh succeeds.
## Testing
Add coverage for replacement and session reuse, recovery and connection races,
lookup and handshake failures, handle preservation, and late RPC responses.

## Why
Refreshing a Noise rendezvous bundle after an unauthorized handshake inherited
the initial registry lookup's retry count. If that lookup had exhausted its
retries, a transient registry error during the refresh failed immediately.
## What changed
Reset the registry retry count along with the operation deadline before
requesting a replacement bundle after a `401` handshake response.
## Testing
Extend the initial Noise connection test to exhaust the first lookup's retry
budget, receive a `401`, then verify that an offline replacement lookup is
retried and connects successfully.

## What changed
- Retry transient environment-registry failures while opening the initial Noise rendezvous connection, including timeouts, interrupted response bodies, retryable HTTP statuses, and temporarily offline environments.
- Bound registry attempts with per-request and overall timeouts, exponential backoff, and a retry limit while returning permanent registry errors immediately.
- Preserve the existing one-time bundle refresh after an unauthorized WebSocket handshake, with a fresh registry retry window.
- Treat malformed complete JSON responses as terminal rather than retryable transport failures.
## Testing
- Cover transient and permanent registry responses, stalled requests, retry limits and deadlines, interrupted bodies, malformed JSON, unauthorized bundle refresh, and session-resume behavior.

## Why
Remote environment connections need to honor Codex's effective outbound proxy policy, including when a rendezvous connection reconnects.
## What changed
- Pass the configured `HttpClientFactory` into remote environment transports and use `WebSocketConnector` for exec-server and rendezvous WebSockets.
- Resolve proxy routes asynchronously so these connections can use the configured system proxy.
- Add connector options that preserve Tungstenite's default TLS behavior and enable `TCP_NODELAY` for latency-sensitive rendezvous traffic.
## Testing
- Verify prepared remote environments connect through a configured system proxy.
- Verify initial and reconnected encrypted relay peers use the system proxy.
- Cover default TLS selection and opt-in `TCP_NODELAY` behavior in the WebSocket client.

## Summary
- add a provider API that supplies a fresh signed WebSocket URL for each
remote exec-server connection
- refresh the signed URL after disconnects and retry once when a
handshake returns `401 Unauthorized`
- allow `EnvironmentManager` consumers to register remote environments
backed by the URL provider
