 - OpenCode Zen: route models to the Zen API shape per family so proxy endpoints are used. (#1416)
 - Browser: suppress Chrome restore prompts for managed profiles. (#1419) Thanks @jamesgroat.
 - Models: inherit session model overrides in thread/topic sessions (Telegram topics, Slack/Discord threads). (#1376)
+- macOS: keep local auto bind loopback-first; only use tailnet when bind=tailnet.
 - macOS: include Textual syntax highlighting resources in packaged app to prevent chat crashes. (#1362)
 - Cron: cap reminder context history to 10 messages and honor `contextMessages`. (#1103) Thanks @mkbehr.
 - Exec approvals: treat main as the default agent + migrate legacy default allowlists. (#1417) Thanks @czekaj.
