get_instrument_state — Read half of the instrument round-trip: parse any Chromologium lab permalink (the URL a visitor shares from the Loom or the Thin-Film workbench) into its full recipe — the validated state, the resolved specimen data (threading plan or film physics), the fringe or thread palette, and the plate/embed URLs.
render_instrument — Write half of the instrument round-trip: given an instrument and a state, return the artefact as text-native output — the Loom yields editable SVG (thread-level rects), dependency-free repeating-linear-gradient CSS, and the weaver's draft; the thin film yields an interference-gradient SVG and its physics-sampled fringe stops.
generate_pattern — Commission a generative pattern from the Pattern Press: Truchet tilings, flow fields, isometric lattices, or interference meshes.
marble_trough — Float archival pigments on a size bath and draw a comb through them — the ebru technique behind old bookbinders' endpapers.
teleprint — Re-type one of the archive's specimens as character art and return it as plain text, ready to paste into a README or a terminal.
list_looks — The curated looks catalogue — named, permalinkable instrument states (the same rail shown on each lab).
export_palette — Colours out in the file formats designers' tools import: GIMP .gpl (also Krita, Inkscape, Aseprite) and Tokens Studio JSON inline; Adobe .ase and Procreate .swatches as base64.
get_material_optics — Retrieve the authored optical coefficients for a catalogued national material — scatter depth, micro-facet roughness, specular anisotropy, metalness, refractive index at 589 nm, and patina rate — plus its tactile profile, damping regime, and the artwork citation.
