What this edition demonstrates

BigInt half-up minor-unit arithmetic with a frozen pricing snapshot.

No ERP integration, customer records, approval or operational offer creation.

The public website hosts a read-only synthetic projection. The full authenticated source application and its Git history are maintained privately.

All fixtures are fictional. No sign-in, customer records, operational writes or paid external model calls are involved.

MATHEMATICAL SPECIFICATION & UNITS

Governing Equations, Inputs, Outputs & Dimensional Conventions

Quayline Pricing Workspace executes deterministic client-side calculations in the browser. Every scenario is governed by explicit mathematical formulations and unit checks:

Net Revenue (cents) = Σ [ Quantity (L) × Unit Price (cents/L) × (10,000 − Discount_bps) / 10,000 ] × (10,000 − Rebate_bps) / 10,000; Margin (%) = (Net Revenue − Total Cost) / Net Revenue × 100

Declared Units & Arithmetic Conventions: Volume in litres (L); prices and revenue in integer USD minor units (cents); discounts and rebates in basis points (1 bps = 0.01%).

Scope & Operational Boundary: Marine-supply offer modelling with volume, discount and margin checks using minor-unit arithmetic. Synthetic frozen snapshots; no ERP, payment, live quotation or contract execution.

REPRODUCIBLE WORKED EXAMPLE & BENCHMARK TABLE

Verified Case Study & Held-Out Reference Table

Worked Verification Case: Case 1 (Bulk Marine Offer, 30-day payment terms): 1,000 L at 185 cents/L ($1.85/L) with 0 bps line discount and 0 bps rebate yields Net Revenue = 185,000 USD cents ($1,850.00). Against synthetic supply & port cost of 234,000 USD cents ($2,340.00), Profit = -49,000 USD cents (-$490.00) and Margin = -26.49%, triggering the margin-floor review warning.

PROCEDURAL USAGE GUIDE

How to Use Quayline Pricing Workspace in 3 Reproducible Steps

Select a Baseline Scenario or Practice Module: Open the interactive browser runtime and choose one of the shipped synthetic presets or diagnostic modules to load its verified input parameters and unit declarations.
Inspect Intermediate Traces & Constraints: Review the computed ledger, error diagnostics (MAE/RMSE/margin/balance checks), or bilingual explanations alongside the governing equations documented on khanway.co.business/methodology/.
Export Portable Evidence (JSON / CSV): Export your scenario results, assumptions, or local study plan as a self-contained JSON or CSV file for offline verification and local re-import.

FREQUENTLY ASKED QUESTIONS

Methodological & Boundary FAQs

What mathematical model and units does Quayline Pricing Workspace use?

Quayline Pricing Workspace applies Net Revenue (cents) = Σ [ Quantity (L) × Unit Price (cents/L) × (10,000 − Discount_bps) / 10,000 ] × (10,000 − Rebate_bps) / 10,000; Margin (%) = (Net Revenue − Total Cost) / Net Revenue × 100. Units: Volume in litres (L); prices and revenue in integer USD minor units (cents); discounts and rebates in basis points (1 bps = 0.01%).

What are the operational boundaries and limitations of Quayline Pricing Workspace?

Marine-supply offer modelling with volume, discount and margin checks using minor-unit arithmetic. Synthetic frozen snapshots; no ERP, payment, live quotation or contract execution. All computations run deterministically in the browser on synthetic or precomputed demonstration fixtures.

How can I reproduce the benchmark results in Quayline Pricing Workspace?

Open the interactive browser workspace at ./run/, select Case 1 to inspect the worked result (Case 1 (Bulk Marine Offer, 30-day payment terms): 1,000 L at 185 cents/L ($1.85/L) with 0 bps line discount and 0 bps rebate yields Net Revenue = 185,000 USD cents ($1,850.00). Against synthetic supply & port cost of 234,000 USD cents ($2,340.00), Profit = -49,000 USD cents (-$490.00) and Margin = -26.49%, triggering the margin-floor review warning.), and export the JSON or CSV evidence ledger.
