The portal's own semantic layer, honed to this corpus. At build
time every document is chunked, embedded, and distilled into static geometry:
embedding-nearest neighbors, nine-bucket category affinity, the five
strongest lines per document by centrality, and cross-shelf candidate
crossings feeding the Registry. Locally, a warm-once server answers free-text
queries — ranked documents with distances plus the query's own affinity profile —
with a terminal twin for the classifier-demo readout.
ON THIS HUB: the precomputed geometry ships and renders
on the Navigator, Reader, and Registry. The live encoder lane lights up when the
local synthesizer runs. Staged next: an opt-in in-browser encoder (quantized, lazy)
and a Wikipedia category-graph fan-out once the internal geometry is worth
extending outward.
