Inputs
| Field | Type | Valid domain |
|---|---|---|
| preMoneyValuation | float | 1,000,000 – 500,000,000 |
| newMoney | float | 250,000 – 100,000,000 |
| targetPostRoundPoolPct | float | 0 – 0.25 |
| existingUnallocatedPoolPct | float | 0 – 0.2 |
- newMoney must be ≤ preMoneyValuation (rounds selling more than half the company are rejected, never adjusted); the pool increase is created pre-money and dilutes existing holders only.
All fields required. Out-of-domain values are rejected with per-field errors — never clamped. Unknown fields are rejected.
