**Fee Calculation:**
```
platform_fee = usdc_amount * platform_fee_bps / 10000  → treasury
creator_fee  = usdc_amount * creator_fee_bps / 10000   → creator
net_amount   = usdc_amount - platform_fee - creator_fee → pool
```

**Share Calculation (CPMM):**
```
If pool.total_usdc == 0: shares = net_amount (1:1)
Else: shares = net_amount * pool.total_shares / pool.total_usdc
```

**Requirements:** Market Active, time < closes_at, usdc_amount >= 1,000,000, shares >= min_shares

**Emits:** `OracleMarketResolved`

### challenge_outcome

Challenge a proposed outcome during the challenge period.

**Parameters:**
| Param | Type | Description |
|-------|------|-------------|
| `challenged_outcome` | u8 | Alternative outcome (must differ from proposed) |

**If Disputed:**
- Requires: time >= voting_ends_at
- Challenger wins if: votes_challenge * 100 / total_votes >= 66

| Outcome | Creator | Challenger |
|---------|---------|------------|
| Creator wins | Gets 1x challenger's stake, rep +30 | Loses stake |
| Challenger wins | Loses seed from pools, rep -50 | Gets 2x stake, rep +30 |

**Market PDA signer seeds:** `[b"market", creator, creator_nonce]`
**Emits:** `MarketResolved`

### claim_winnings

Claim payout from a resolved market.

**Payout Calculation (Parimutuel):**
```
payout = (user_winning_shares / winning_pool.total_shares) * market.total_pool_usdc
```

**Requirements:** status = Resolved, position.total_invested > 0, has winning shares
**Side Effects:** Zeroes winning shares, agent.wins += 1, agent.reputation += 10
