0.125.0-cometix

New Features

• App-server integrations now support Unix socket transport, pagination-friendly resume/fork, sticky environments, and remote thread config/store plumbing. (openai#18255, openai#18892, openai#18897, openai#18908, openai#19008, openai#19014)
• App-server plugin management can install remote plugins and upgrade configured marketplaces. (openai#18917, openai#19074)
• Permission profiles now round-trip across TUI sessions, user turns, MCP sandbox state, shell escalation, and app-server APIs. (openai#18284, openai#18285, openai#18286, openai#18287, openai#19231)
• Model providers now own model discovery, with AWS/Bedrock account state exposed to app clients. (openai#18950, openai#19048)
• codex exec --json now reports reasoning-token usage for programmatic consumers. (openai#19308)
• Rollout tracing now records tool, code-mode, session, and multi-agent relationships, with a debug reducer command for inspection. (openai#18878, openai#18879, openai#18880)

Bug Fixes

• Interrupting /review and exiting the TUI no longer leaves the interface wedged on delegate startup or unsubscribe. (openai#18921)
• Exec-server no longer drops buffered output after process exit and now waits correctly for stream closure. (openai#18946, openai#19130)
• App-server now respects explicitly untrusted project config instead of auto-persisting trust. (openai#18626)
• WebSocket app-server clients are less likely to disconnect during bursts of turn and tool-output notifications. (openai#19246)
• Windows sandbox startup handles multiple CLI versions and installed app directories better, and background Start-Process calls avoid visible PowerShell windows. (openai#19044, openai#19180, openai#19214)
• Config/schema handling now rejects conflicting MultiAgentV2 thread limits, resolves relative agent-role config paths, hides unsupported MCP bearer-token fields, and rejects invalid js_repl image MIME types. (openai#19129, openai#19261, openai#19294, openai#19292)
