RESONANCE ENGINE
Implement an ERC-20 swap-only policy (LP↔user) with score-based fees + bounded surge control + deterministic buyback/burn + loyalty rewards + self-expiring launch shield.
State: mapping(address=>uint16) score (0..100), firstSeen, lastActive, lastSell, weeklyPool, vault, surchargeBps, surchargeUntil, lastResonance.
Score (lazy-updated on transfers): increases with wallet age + recent txs; decays linearly to 0 after 30d inactivity.
Wallet fee: feeBps = 200 - score*(190/100) (min 10, max 200).
Pressure valve: if 1h volume >15% supply OR clustered sells, add surchargeBps up to 300 for ≤2h; auto-expire. Cap total fee ≤500 bps.
Routing: collected fee split 50% burn, 30% auto-LP, 20% to vault.
Resonance: executeResonance() public, ≥6h cadence; spend ≤25% of vault (daily cap) to buyback+burn.
Weekly loyalty: slice of vault funds weeklyPool; distribute to wallets with ≥3 tx/24h and no sells/72h.
Launch shield: first 2h: maxTx 0.5% supply + 10m buy cooldown; disable.
