Source PNG from the MPS lumbda-logos product is already an inverted λ
(hooks at top-left + bottom-right, V-body). My prior commit applied
vertical + horizontal flips on top of that, which undid the inversion
and produced a right-side-up calligraphic λ — the opposite of what
the artwork was drawn to express.
Regenerate both PNG variants (lumbda-logo.png black,
lumbda-logo-green.png #227842) directly from the source with no
flips. Only transform: alpha-from-brightness so anti-aliased edges
survive over any background.
Homepage img src picks up ?v=2 so any browser with the flipped
version in disk cache re-fetches. Logo size stays 3.33× the
wordmark font (10.66rem). PDF + HTML rebuilt — embed-images.py
base64-inlines the new PNG into the HTML automatically.
Fetched the lumbda-logos artwork from
media.unturf.com/c/fbd3d473-.../lumbda-logos (a MakePostSell product),
applied both flips (vertical + horizontal, = 180°) at bake time so the
PNG ships oriented correctly without any CSS transform dance, and
recolored non-background pixels to brand green (#227842) with alpha
derived from pixel brightness so anti-aliased edges stay smooth.
Two PNG variants ship under whitepaper/diagrams/:
* lumbda-logo.png dark ink for print contexts
* lumbda-logo-green.png #227842 for web
www/ carries symlinks to both.
Homepage (www/index.html): replaces the CSS-rendered λ with an
<img class="lambda-mark"> element sized 9.6rem — 3× the 3.2rem
wordmark font — stacked below "lumbda." on its own line.
Whitepaper (whitepaper/lumbda-whitepaper.rst): adds the logo as the
first figure above the permacomputer-logo, 24% width, centered.
Regenerated PDF + HTML; embed-images.py base64-inlines the new file
automatically so the HTML stays single-file.
CI (.gitlab-ci.yml): generalizes the symlink resolver from two
explicit `cp -L` calls into a `find www -type l` loop, so every
current and future symlinked asset deploys without per-file CI edits.
Previously the HTML whitepaper referenced diagrams via relative paths
(src="diagrams/X.png"), which 404'd because the docroot does not carry
a mirror of whitepaper/diagrams/. The "HTML whitepaper" thus showed
broken image stubs instead of the architecture figures.
Fix: a post-processor (whitepaper/embed-images.py, stdlib Python) runs
after rst2html5. Every <img> with a relative src gets base64-inlined
as a data: URI with inferred MIME. Any .svg reference would splice in
as an inline <svg> element, surfacing alt text as <title>; the current
RST only uses the .png variant of gnu-logo so no SVGs inline for now,
but the path works when we switch.
Makefile's whitepaper-html target chains the embed step after the
existing sed passes for the uncloseai.js script tag and the meaningful
<title>. Title tweaked to "feedback as a primitive" to match the
homepage tagline.
Result: whitepaper/lumbda-whitepaper.html grows from 180 KB to 4.6 MB
(base64 inflation on ~2 MB of diagrams), and it now opens offline as
a single file — no network fetches for figures, no docroot mirror
needed.
CLAUDE.md rewritten to avoid the verb "to be" and to prefer "a"/"our"
over "the" when a thing counts as one of many or as shared. Same rule
applied to www/index.html (tagline now "feedback as a primitive", body
prose cleaned of is/are/be, table header now "What a tier buys",
section heads trimmed of definite articles). Monospace body stays,
ChunkFive titles stay.
Whitepaper now ships in two formats:
* Makefile target `make whitepaper-html` runs rst2html5 with
embedded minimal.css + responsive.css (docutils bundled), then
injects the same uncloseai.js module script that the homepage
carries, and stamps a meaningful <title>. 180 KB self-contained.
* PDF build target renamed to `make whitepaper-pdf`;
`make whitepaper` now builds both.
www/lumbda-whitepaper.html symlinks to the generated HTML (same
pattern as the PDF symlink). .gitlab-ci.yml resolves both symlinks to
real files before rsync so the proxy gets byte-identical copies.
Homepage now exposes both formats side-by-side via two .cta buttons
and the footer lists HTML + PDF.
