Sessions resume more reliably while proxy and permission controls expand
Codex preserved session identity across resumes, exposed permission-profile availability, and added more system-proxy plumbing.
The most useful changes in this window cluster around continuity and managed environments: resumed threads keep their session IDs, clients can inspect which permission profiles are available, and the networking layer gains additional proxy support.
Alpha release context: 3 official tags were published that UTC day (rust-v0.142.0-alpha.11, rust-v0.142.0-alpha.12, rust-v0.143.0-alpha.1). The full comparison contains 39 commits and at least 300 changed files.
Evidence
Codex now persists session IDs when a thread is resumed.Why it matters: Clients and observability tools can correlate work before and after a resume without treating it as an unrelated session.

The shared proxy work adds a Windows system-proxy resolver.Why it matters: This is groundwork for Codex traffic to respect managed network settings on Windows rather than requiring separate proxy configuration.
