Prediction surface
Tell me what happens next, and what to do about it.
The tape desk, the hub exchange board and the corridor pricing ledger each reported a table of what had already happened. Folded into this one surface they answer the only question a treasury asks: how long will this take, what will it cost, what can move against me, and what should I do first. Every number carries a p50, a p90, the drivers behind it and the manual-desk comparator — and the three reporting desks now live behind the forecast, as evidence for it rather than as work of their own.

Charges model: AD Category-1 margin of 5–22 bps by corridor depth, correspondent ₹1,850 and cable ₹1,100 per instruction, GST at 18% on bank charges, and treaty withholding read from the hub record. Every row is bound to the capture digest of the print that priced it, so the rate on the ledger is provably the rate that was live when the treasurer acted.
