Sextant, the venture-analysis grill

Field notes

The intake asks for practical constraints rather than only a pitch: geography, capital available, first-revenue timing, unfair advantage, and limits. The described review combines four research lenses with a red-team pass, then produces a verdict and a kill-contract. The page identifies Fable 5 as its reasoning fleet and Grok 4.6 as its brain scouts, but the extract does not show a completed fix or disclose how claims receive their grades.
