# Marketplace Fee & Net Margin Calculator
Computes exact net payouts after deducting platform admin fees and shipping extra charges.
## Hybrid Execution Model
Pass parameters to `engines/marketplace-fee-calculator.js`:
* **Tokopedia**: Regular (3.8%), Power Merchant (4.5%), Power Merchant Pro (5.5%), Official Store (6.5%).
* **Shopee**: Non-Star (4.0%), Star (6.0%), Star+ (6.5%), Mall (8.5%).
* **TikTok Shop**: Standard (4.5%), Mall (6.5%).
* **Gratis Ongkir Extra**: 4% capped at Rp 10.000 per item.
## Trust Envelope (Confidence Contract)
Every engine output must be wrapped in a structured envelope declaring production trust attributes:
* **`regulatory_framework`**: Applying regulation with article references (e.g. `PP No. 58/2023 jo. PMK 168/2023 - TER`).
* **`ruleset_version`**: Versioned Id of the `engines/rules/*.json` ruleset consulted (e.g. `PPH21-2024 v1.0.0`).
* **`effective_window`**: `[effective_from] – [effective_to]` of the applied ruleset.
* **`integrity_status`**: `VERIFIED` after SHA-256 ruleset check, or `UNVERIFIED` — never present silent calculations when UNVERIFIED.
* **`risk_level`**: Contextual `LOW / MEDIUM / HIGH` per skill risk metadata.
* **`requires_human_review`**: `true` for HIGH risk outputs — mandatory professional sign-off before filing, payment, or execution.
* **`currency`**: IDR, rounded to the nearest whole Rupiah unless another precision is stated.
* **`as_of`**: The simulation/effective date used to select the ruleset.
