opusplan is in the picker and does nothing on this install: it is a per-MODE model switch (Opus while in
plan mode, Sonnet at rest — the CLI's own strings call them the upgrade and resting models), and
claude-manager hardcodes permissionMode: 'bypassPermissions', so plan mode is never entered. Not
orchestration, which is what the name suggests and what we both assumed.
Making the mode reachable is the fix. setPermissionMode is a control request on the live query, same channel
as the setModel that landed in 4c24df93, so the mechanism is proven. The hard part is ExitPlanMode: it is a
permission decision, and bypassPermissions auto-approves it, so a naive toggle produces a planner that
instantly approves its own plan. canUseTool is the hook, and whether it can be supplied after session
creation is the one thing to verify before designing any UI.
Records the landmines too — bypassPermissions is deliberate per CLAUDE.md and must be restored on exit, and
a canUseTool promise that never resolves wedges the turn.
