Provenance Blame.

I wanted the site to be honest about what made each piece. A single badge says "AI-assisted" — but which parts? This sketch answers that at the section level.

The model drafted this paragraph from a one-line prompt; I then rewrote the second half and tightened the verbs. That mixed authorship is exactly the "hybrid" case the yellow gutter marks.

const composition = (doc) => doc.reduce((m, b) => ({ ...m, [b.prov]: (m[b.prov] ?? 0) + 1 }), {})

This explanatory blurb was generated wholesale and pasted in unedited — red gutter, no human touch. Useful, but the reader deserves to know.

The summary bar above sums these blocks into one composition reading, so the per-item badge and the per-section blame always agree.

Hover any block to inspect its origin; the gutter chip and this column stay in sync. Toggle the gutter labels for a denser or more legible read.
