Left to right is time. Each row is one of the 3 disciplines Tenable carried, ordered so kindred disciplines sit next to each other rather than alphabetically — a landscape only means anything if neighboring rows belong together. Height is the work running in that domain in that year, weighted by what failure would have cost — life-safety ×3, a statutory obligation ×2.2, the estate itself ×1.5, an evaluation ×1. Every project declares which of those it was, so each ridge traces to an entry you can open and disagree with. Only the work that named this manufacturer is counted, so this is the shape of what it carried rather than of the record around it. Height and color are on the record-wide scale rather than this page’s own, so a modest estate draws a modest landscape and any two of these pages can be read against each other.
Nessus.
Declared on each entry rather than listed here, so this page cannot drift from the work it describes. What each entry named is quoted as it stands, with how much of that project rested on it and what stands behind the claim beside it. The first of those drives the height of the surface above.
