kennethreitz ce93f429a2 Add Knowledge: the vault's reference shelf, crosslinked across the site
Publish the Obsidian vault's Knowledge folder as /knowledge (881 notes,
67 folders), with a Knowledge item in the nav and footer.

- scripts/import_knowledge.py regenerates data/knowledge from the vault:
  slugged paths, folder notes as index pages, wikilinks resolved to site
  links (or plain text), callouts, highlights, and Dataview tables
  rendered statically. Personal notes are withheld via an exclusion
  list plus a privacy guard.
- tuftecms/core/knowledge.py builds a concept index from note titles and
  aliases. First mentions on ordinary pages link to their Knowledge note
  (capped, never in headings, code, links, or sidenotes); Knowledge pages
  list related notes and where they're mentioned across the site; other
  pages get a Related Knowledge block.
- Knowledge URLs join sitemap.xml (so the sweep test covers them), never
  displace existing legacy slugs, list alphabetically, and mermaid
  diagrams render client-side only on pages that have them.

Dorian

A minor scale that keeps one window open to the light.


The Mode

Dorian is the second mode of the major scale — start on the second degree and run to its octave. Built on C, it borrows its notes from B♭ major, giving a minor-sounding scale with a flattened third and seventh but, crucially, a natural sixth left intact. That single unflattened note is what separates Dorian from the plainer natural minor.

The result is a mode that is unmistakably minor in temperament yet refuses to be gloomy. It has a wistful, hopeful quality — melancholy with the collar turned up against the cold, a sadness that still looks outward. Among the minor modes it is the most balanced and the most cool-headed.

Character

Everything in Dorian turns on that natural sixth. In a minor context the ear expects the sixth to be lowered, so hearing it raised lends a lift — a splash of brightness against the minor third’s shadow. It keeps the mode from settling into pure sorrow, producing instead something poised and bittersweet, sophisticated rather than mournful. Symmetry helps too: the scale reads the same forwards and backwards, which gives it an even, self-contained balance.

In Practice

Dorian is the workhorse of modal jazz, funk, and rock — think extended vamps that stay on one minor chord and let the natural sixth glow. It colours a great deal of Celtic and English folk song, medieval church music, and countless minor-key grooves that need to breathe rather than mourn. It is arguably the most-used mode after the two that define major and minor themselves.
