The headline is a stance, not a grade. Business quality and price are scored separately and crossed into four positions, so "the numbers support the price" and "cheap, and here is the catch" are different verdicts rather than the same middling number. Each stance also carries the specific figure that would change it and the evidence that would prove it wrong, because a judgement that cannot be wrong is not a judgement, and a reader who knows what to re-check does not need me afterwards.

Everything runs in the page the reader already has open, with no network calls at all. That was a privacy decision first — nobody's holdings or research interests leave their machine — and it turned out to be a correctness decision too. The scoring engine is a pure function of the captured page, so a bug report containing only a URL reproduces the exact report the user saw.

A universal set of thresholds lies confidently in predictable places, so some sectors get their own model. Return on capital employed is meaningless for a bank, where deposits are the raw material sitting in the denominator; a healthy lender prints single digits and a universal curve reads that as value destruction. Cyclicals get a peak-earnings check, because a steel company at the top of its cycle shows its best margins and its lowest multiple in the same quarter, and that trap is the most expensive mistake retail makes.

An early build printed over two thousand words. A retail investor gives you about thirty seconds, so the report is tiered to a decision on the first screen with the analyst depth one click below, and a test fails the build if that first screen exceeds its word budget in any of the three languages. The constraint means a new feature has to displace something rather than quietly adding to the reading load.

It is deliberately not advice. There is no buy, sell or hold instruction, no price target and no entry price anywhere in it, and tests assert that none of the generated copy in any language drifts into that register. The report tells you whether the numbers justify the price; what to do about that is the reader's call, and keeping that line sharp is what makes the tool publishable at all.
