## What a subscription unlocks

### Your saved skill-decay trend

Every diagnostic retake plotted over time, so a real line — not one reading — tells you what’s actually decaying.

### Daily adaptive practice

A short, unassisted drill loop that targets your soft spots and spaces reviews so the skill sticks.

### The full drill library

Browse and attempt the entire bank by category and difficulty — every attempt counts toward mastery.

### Per-skill mastery

Watch each skill climb Cold → Warming → Solid → Sharp, and get warned before one quietly fades.
