The same validation rules, including the check that `sdkMcpServers` and `webSearchIsolationExemptMcpServers` must be arrays of strings, and the same underlying settings appear unchanged.\n\n**Why**\n\nThis looks like housekeeping rather than a behavior change; nothing here should affect how these commands work.\n\n- Flag `tengu_ptc_enabled`: Not enough to say (read for one account on one subscription tier against v2.1.267; this account: no value returned, anonymous baseline: no value returned, compiled default: on)\n- Area: SDK\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 0\/5"}
