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.

Five Stroke Roll
Two diddles and a pop — the shortest complete roll.
The Rudiment
The five stroke roll is the most compact of the measured rolls and one of the most useful. It packs two double strokes into a quick roll that resolves onto a single accented tap, giving a crisp "brrr-DAT" that punctuates phrases everywhere from the concert stage to the drum set. Because it is short, it is endlessly repeatable and hand-to-hand reversible, making it the ideal entry point into the numbered-roll family and a favorite for locking rolls to the beat.
Sticking
The standard sticking is two doubles plus a terminating accent — five strokes in all: RRLL R, accent on that final note, then reversed as LLRR L. Counted, the two diddles typically fall as the buzz and the accent lands on the beat, so the roll leads into the pulse rather than starting on it. Alternating the lead hand lets you play it continuously off either side.
How to Play
Play the four rolled notes as clean, tight doubles — closed for a sustained sound, open for a rudimental bite — then drive the fifth stroke up for the accent. The two diddles stay low and even; only the final tap gets height and weight. Keeping the roll compact and the accent snapping cleanly on the beat is the whole exercise. Practice it leading with each hand.
In Practice
The five stroke roll is everywhere: orchestral punctuation, marching cadences, jazz comping, and quick snare accents on the kit. It grows directly out of the Double Stroke Open Roll and extends into the Seven Stroke Roll and Nine Stroke Roll as you add diddles.
