Your Personal Cosmos, curated as a dossier.

The Atelier's synthesis engine treats every dossier as a point in an eight-dimensional curatorial space, then collapses that point onto a single interpretive vector we call V_cosmos. The projection is deliberately conservative: 40% of the vector's weight is drawn from the Jungian mind axis (the cognitive typology inferred from your selected psychological archetype), 35% from the sky axis (the natal geometry of Sun, Moon, and Rising placements read as aesthetic rather than predictive signals), and 25% from the emblem axis (the tarot emblem chosen from the twenty-two Major Arcana, treated as a symbolic compression of the querent's stated aesthetic). Formally, for any input triple we compute V_cosmos = 0.40·V_mind + 0.35·V_sky + 0.25·V_emblem, where each component vector is itself a unit vector in the same eight-dimensional basis. Because the sky axis carries the second-largest coefficient but is composed of three independent zodiac positions, we first reduce the trio through a normalized 3-to-8 embedding and then re-normalize, ensuring that no single placement dominates the composite. The weighting was calibrated so that the mind axis remains the primary interpretive anchor, the sky axis provides contrast and friction, and the emblem provides chromatic and thematic resolution.

Once V_cosmos is established, the engine performs a cosine-similarity sweep against a curated reference corpus drawn from The Metropolitan Museum of Art Open Access collection, restricted to works released under CC0 and filtered to paintings whose dominant palettes can be extracted with sufficient confidence. Cosine similarity measures the angle between V_cosmos and each reference painting's own eight-dimensional character vector, which we derive from hue distribution, value contrast, edge density, symbolic subject clustering, and period attribution. The top-ranked painting becomes your "met twin," presented alongside artist, year, accession link, and a derived Kelvin figure. That Kelvin value is not decorative: we pass the painting's mean chromaticity through a simplified blackbody approximation inspired by Studio Kelvin physics, yielding a correlated color temperature in kelvin that lets you compare the emotional "warmth" of your synthesis to the literal physical warmth of the reference work's light. A low kelvin reading indicates an amber, candle-lit register; a high reading indicates cool, overcast, or north-light register. The 5-gon radar and the five-swatch palette you see in the dossier are both direct visualizations of the same eight-dimensional vector, projected down for legibility.

The editorial method rests on three commitments. First, transparency: every numeric readout in the dossier — harmony, friction, kelvin, optical density — is reproducible from the stated weights and the published embedding, and the code that produces them ships in an open, readable JavaScript module. Second, restraint: the engine never claims diagnostic authority, never predicts events, and never ranks one archetype above another; the vector mathematics are descriptive of an aesthetic coordinate, not of a person. Third, scholarship: the Met twin is selected from genuine museum metadata, and the reading text you receive is composed from a curated lexicon of art-historical and depth-psychological descriptors, hand-reviewed by the Atelier's editors. Where the mathematics produce friction between axes — say, a cool emblem against a warm sky — the reading names that tension explicitly rather than smoothing it away, because tension is usually the most interesting part of a chart. The protocol suggests how to sit with the result: read the thesis once, note the tension, and return to the palette after a day's interval to see whether the colors still read the same. This is the Atelier's way of honoring both the rigor of the vector and the slowness of genuine reflection.
