## Why
Codex can run a remote exec server through the Noise relay, but the
normal
environment-manager path could not establish an
environment-registry-backed
harness connection. Signed rendezvous URLs and harness authorizations
are
short-lived, so reconnects must fetch a fresh bundle instead of
retaining
stale connection credentials. A stalled registry request must also fail
within
the regular remote connection deadline, without exposing these
credentials in
debug logs.
Issue: N/A (internal environment-service integration).
## What Changed
- Add environment-manager configuration for a registry-backed Noise
rendezvous
environment.
- Request a fresh bundle from
`/cloud/environment/{environment_id}/connect` for every physical harness
connection, using the existing 10-second remote connection timeout.
- Share the Environment Registry register, connect, and validate wire
payloads
through `codex-exec-server` and `codex-core-api`.
- Redact the signed rendezvous URL and harness authorization from the
public
connect response's `Debug` output.
- Add focused coverage for registry bundle retrieval, stalled requests,
and
credential redaction.
## Why
Services that proxy the exec-server environment registry endpoints need
to deserialize and forward the same Noise registration and harness-key
validation payloads. Those wire models currently live as private,
serialize-only structs in `exec-server`, which forces consumers to
duplicate the contract.
## What changed
- Add owned serde models for registration and harness-key validation
requests and responses.
- Use those models in the existing exec-server registry client.
- Re-export the models from `codex-exec-server` and `codex-core-api`.
- Keep the harness authorization request free of a derived `Debug`
implementation so it is not accidentally logged.
## Testing
- Focused exec-server registration and harness-key validation tests: 2
passed.
- `cargo check -p codex-core-api`
The full `codex-exec-server` suite compiled and ran 254 tests: 222
passed, while 32 existing filesystem sandbox tests could not run under
the nested macOS sandbox (`sandbox_apply: Operation not permitted`).
