## Story 004: Review weekly and all-time history

**Persona:** Sasha, 32, a therapist who uses pomodoros to manage between-session admin work. They want to see patterns over time and prove to themselves that structure helps.

**Situation:**

Sasha reviews their week on Sunday evening. They want to see: Did I keep my rhythm? Am I holding the boundaries I set? The numbers matter less than the pattern.

**Need:**

As Sasha, I want to see my session count and total focus time for this week and all-time, so that I can notice whether my habits are holding and celebrate the weeks that work.

**Acceptance:**
- The app has a 'history' or 'stats' view showing completed sessions and total focus time for the current week
- The same view also shows all-time totals (total sessions ever, total hours ever)
- The view is simple enough to parse at a glance without clicking through multiple screens
- Sasha can see the data without exporting; the history is readable inside the app

**Tier:** core

**Confusion-flags:**
- Does 'this week' mean calendar week or rolling 7 days? I'm assuming calendar week (Monday-Sunday) but that's a settings call.
- How far back does 'all-time' go? Since the user first used the app? Do we ever archive old data, or keep everything? This is a database design question, but it affects what the user can see.
