Shared Target Progress Stays in Sync

Why it matters

• Instant cross-target updates – When you mark a calendar event as complete (or undo it), every target task in the shared progress group updates immediately in the sidebar. No refresh needed.
• Optimistic UI fixed – Our Zustand store now mirrors the backend batch update, so the loading indicator disappears the moment the shared progress kicks in.
• Consistent completion math – We capped front-end deltas to required completions, which keeps shared tasks aligned even if some targets already finished their repetitions.

Everyday example

Split goals, one habit

Imagine you’re splitting your mornings between:

• Crush the fall semester — a target focused on deep study blocks
• Level up tech career — another target for portfolio projects and networking

You build an “AM Focus Sprint” task, link it to both targets, and enable shared progress. Now every time you wrap a Pomodoro session and check the calendar event as completed, both targets jump forward by one repetition. If you slide a block back to pending, each target rewinds together, keeping your plan honest without extra clicks.

Gym meets wellness

Or take a classic fitness combo:

• Strong like summer — weight training to build muscle
• Clear mind mornings — cardio and mindfulness to start the day

The shared “Morning Gym” task means a single treadmill grind advances body and mind alike. No duplicate logging, no mental overhead—just consistent momentum across your goals. *** End Patch
