## 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.

## What changed
- Add `codex exec-server forward --connect ws://HOST:PORT` to register an
existing WebSocket exec-server as a remote environment.
- Open a separate destination WebSocket for each authenticated Noise relay
stream and forward complete payloads unchanged in both directions.
- Preserve large messages through WebSocket fragmentation and coordinate
disconnects, close acknowledgements, and pending output delivery.
## Testing
- Cover CLI validation, opaque payload forwarding, disconnect handling, and
destination close behavior.
- Verify commands and large file transfers through the complete relay and
forwarding path.

## What changed
- Add a `NoiseStreamHandler` abstraction that owns payload encoding, decoding,
and connection processing while the virtual stream handles framing,
encryption, and multiplexing.
- Reassemble authenticated payloads as opaque bytes, with the existing
JSON-RPC processor supplied as a handler implementation.
- Have the physical relay send a reset after the current stream instance
closes, including when its processor exits before the writer task.
## Testing
- Verify local JSON-RPC decoding creates the queued request span before queue
admission.
- Verify a processor exit resets the corresponding Noise harness stream.

## Why
The transport in
[openai/codex#26242](https://github.com/openai/codex/pull/26242) needs
to be used by every remote orchestrator-to-executor connection before
JSON-RPC traffic starts.
## Changes
- Generates one executor Noise identity when remote exec-server starts
and registers its public key.
- Creates a harness identity for each physical remote environment
connection.
- Fetches a fresh registry bundle before connecting and validates the
authenticated harness key before completing the executor handshake.
- Multiplexes encrypted logical streams over the existing executor
WebSocket.
- Adds bounded stream, handshake-failure, and reassembly state.
- Adds safe lifecycle diagnostics without logging keys, authorizations,
plaintext, or ciphertext.
- Covers reconnects, replay rejection, validation failure, framing
limits, and encrypted JSON-RPC tool traffic.

## Why
Rendezvous forwards traffic between the orchestrator and exec-server.
The endpoints need to authenticate each other and encrypt that traffic
without trusting Rendezvous with plaintext or endpoint keys.
## Changes
- Adds a hybrid Noise IK channel through Clatter using X25519,
ML-KEM-768, AES-256-GCM, and SHA-256.
- Binds each handshake to `environment_id`, `executor_registration_id`,
and `stream_id`.
- Pins the registry-provided executor key and carries the harness
authorization inside the encrypted handshake.
- Orders relay frames before consuming Noise nonces and fragments large
JSON-RPC messages into bounded records.
- Bounds handshake payloads, frames, streams, and message reassembly.
Runtime activation is in
[openai/codex#26245](https://github.com/openai/codex/pull/26245).
