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.

Fifties Progression
Under the streetlight, a chord for every slow dance.
The Progression
The fifties progression — I–vi–IV–V — is the sound of doo-wop and the American ballad at midcentury. It steps down from the bright tonic to the relative minor, softens into the subdominant, and then leans on the dominant to pull the loop back home. That constant, gentle rocking between major sunlight and minor shadow gives the progression its swaying, nostalgic feel, ideally suited to a slow triplet feel and stacked vocal harmonies.
The vi is again the emotional pivot, but here it arrives second, right after the tonic, so the wistfulness colors the phrase early before the IV and V restore optimism. The cadence on V demands repetition — the loop wants to keep circling — which is why so many of these songs feel like they could sway on forever beneath a mirror ball.

In Practice
It defines 1950s pop and doo-wop ballads — "Stand By Me," "Earth Angel," "Blue Moon," "Every Breath You Take," and "Duke of Earl" all rock through these four chords. The progression is a rotation of the same four-chord family as the I-V-vi-IV and vi-IV-I-V loops, reshuffled to place the tonic first and the dominant last for that yearning, unresolved turnaround.
