## Token Lifecycle

Four.meme tokens progress through several stages:

1. **Created** — Token deployed on bonding curve
2. **Completing** — Approaching graduation threshold (80-100%)
3. **Completed** — Bonding curve filled
4. **Migrated** — Graduated to DEX liquidity pool

Use `graduationPercent`, `completed`, and `migrated` fields to track token progression.
