How BhaavBrief sources, writes, and checks every brief

MCX and NSE prices — spot, futures, open interest — are read live from an exchange data feed. Global reference prices (COMEX gold and silver, LME copper, WTI and Brent crude, USD/INR) come from a separate global market data feed, which also serves as the fallback source whenever the live exchange feed for a specific MCX instrument is temporarily unavailable.

Every price snapshot carries a timestamp. If a feed fails, the brief shows the last known value with an explicit "stale" marker rather than silently reusing an old number as if it were current — a brief is never allowed to present carried-forward data as live.

Import-parity figures (the MCX price versus the landed-cost equivalent of the global price, converted through USD/INR) use a single conversion module shared by the Price Bridge, the publish gate, and the brief generator itself, so the same number can't drift between where it's shown and where it's checked.

Each weekday at market open, the day's price snapshot, open interest, and the relevant macro/event calendar are assembled and handed to an AI generation step that writes the narrative — never the reverse. The system does not decide what happened and then look for numbers to fit; the numbers are fixed first, and the writing has to account for them.

Every statistic beyond the day's live prices — a historical percentage, a seasonal pattern, a prior-edition reference — must trace back to a maintained claims ledger. The model is not permitted to state a number that isn't either in the day's snapshot or in that ledger; there is no path for an invented statistic to reach a published brief.

Before anything goes live, every generated brief passes an automated two-layer check. The first layer is deterministic: every rupee and dollar figure in the text is matched against the source snapshot, with tolerances only for things that are legitimately approximate (support/resistance levels, intraday ranges).

The second layer is a semantic consistency pass that re-reads the brief the way a careful editor would — checking that the numbers in the headline, the body, and the price-bridge table all agree with each other and with the snapshot, and that the day's narrative doesn't contradict itself.

A brief that fails either layer is not published. There is no manual override that skips this step for a specific day's content.

Some editions include an "Edge of the Day" — a specific, falsifiable price level to watch, stated as a level and a direction, never as a buy or sell instruction. The next trading day's brief checks that level against the actual close before writing anything new, and records the verdict — confirmed, rejected, or unresolved — permanently.

Nothing gets quietly removed from that record. The next morning's brief states the verdict plainly, including the misses.
