"Canon" was leaking onto the public site — a nav item, a footer block, a
page title, a set of CSS class names. It was also driving content
decisions it had no business driving: the backlog was ordered around
which references were still unused, which is curation dressed up as
planning.
The page is now /references/, the list is documented as a bibliography
to grow rather than a canon to curate, and the backlog says plainly that
a sin earns a slot by being worth a page — sources are found to support
it, never the reverse.
Adds six sources (Cairo's Truthful Art, Few's Show Me the Numbers, the
Economist's audit of its own charts, Kosara's eagereyes, WTF
Visualizations, Datawrapper's dual-axis piece) and roughly doubles the
citations on the five published sins, to 5-7 each. Two of the new notes
point at sources that complicate our own position rather than back it.
The Economist essay ships without a URL rather than a guessed one.

Writes two sins off the backlog. The inverted y-axis is the egregious
one: the fill hangs from the top and the line descends while the values
climb, with every element individually defensible. Aspect ratio is the
quiet one: same twelve numbers, same y-range, only the shape of the box
changes.
Adds Cleveland, McGill & McGill 1988 to the canon — banking to 45 comes
from the shape-parameter paper, not the 1984 ranking already cited, so
citing the latter for it would have misattributed the claim.
Also renames sin slugs to match their retitled pages, and rewrites the
summaries that had started echoing those titles.
Gives line-chart points their mark color explicitly; "point": true was
falling back to Vega's default blue on a red or green line.

Titles are scanned in the gallery and recognized in a link, so they
should say what the sin is rather than pun about it. Retitles the three
published sins and the backlog's working titles, and records the rule in
CLAUDE.md: the title names the problem, the poke carries the voice.
Filenames are untouched, so existing URLs still resolve.

Its chart-type "what to consider" posts and four-part color-scale series
cover ground nothing else in the canon does. Adds a backlog entry it is
the leading authority on (stacked columns, where only the bottom series
shares a baseline), and closes the citation gap on the rainbow-color-scale
sin — that one now waits only on our own sequential-ramp validation.

Ranks the next six sins by working backwards from the references we
already vouch for: six of fifteen canon entries were uncited, and each
idle one points at a sin worth writing. Also records the candidates our
build-time Vega-Lite pipeline can't prove honestly yet, so we stop
rediscovering them.
