The Anthropic brand faces captured in ~/colors (Sans, Serif, Mono, Anthropicons;
the anthropic.com "Web" 26.043.1 variable cuts, 14 files pinned by sha256) become
the fleet's own font suite, installed exactly the way the Apple faces are: one
0444 tarball per package on nas:/mnt/fast/fonts/anthropic/, requireFile-pinned
in pkgs/anthropic-{mono-nerd,ui,webfonts}.nix, seeded nightly by
update-center-seed. No font byte enters this repo (.gitignore now rejects them).
pkgs/fontbuilder is the press, a self-contained package that ships the recipe
and no bytes (`nix run .#fontbuilder -- <capture> <out>`, ~4 min): instance the
variable Mono to 12 statics, normalize names and style bits, completeness-merge
Greek/Cyrillic/math/braille from JetBrains Mono, DejaVu Sans Mono and Maple Mono
NF (every grafted glyph carries its donor as a name suffix), ligaturize from
Fira Code 3.001, re-seat each ligature against Anthropic's own strokes, Nerd-
patch last (--complete --mono --makegroups 4, 3.5.1), restore the ten PUA
glyphs the patcher overwrites, and canonicalize head+FFTM so two runs are
byte-identical (--verify-repro proved it on all 12+5+7 artifacts and the three
tarballs). The Sans/Serif stay variable (wght+opsz) with the doubled-"Web"
names, the missing italic bit on the variable row, the Serif wght-300 default
and the STAT " Italic" doubling repaired; the webfonts land under
share/webfonts via home.packages and a fontconfig glob reject, because
fontconfig here indexes woff2 and would contend with the TTFs.
Measured on the pressed faces: 13,440-13,444 codepoints per terminal face,
every advance 1200, braille 256/256, calt 136 lookups, nameID16
"AnthropicMono Nerd Font Mono" (28 of 31 chars), fc-scan spacing 100 on all
12 (the Light Italic source instanced to 90 before the phantom-delta repair).
Mono tarball 2,571,132 B. Acceptance suite in pkgs/fontbuilder/tests (kitty's
own resolver, shaping from the exact face, coverage, alignment, archive shape,
no live fontconfig side effects) passes on this press.
update-center-seed.nix now carries full archive paths (two vendor dirs), an
eval-time font-vs-font GC-root-name guard and a shell-time font-vs-node guard
(a tarball named tally.tar.zst used to clobber seeds/tally silently).
Docs: docs/fonts/{README,anthropic-suite,nas-and-bootstrap}.md and
pkgs/fontbuilder/README.md. Personal use only, per Tom's ruling; the faces
have no published licence and are never redistributed.
This commit installs the packages only; the consumers (kitty, fontconfig
generics, GTK) move in the next commit, after the review window.

… suite Approved by Tom in the review window (kitty spawned on the live niri session with the built packages through a private fontconfig; the process mapped the four AnthropicMonoNerdFontMono faces and nothing from Liga SFMono). kitty.conf names the family in the family="…" style="…" form, the only one whose result depends neither on the monospace alias nor on nameID4 surviving a patcher release (kitty looks bare strings up verbatim and falls through to fc_match silently; measured table in the file). Bold stays SemiBold. fonts.fontconfig.defaultFonts puts Anthropic Sans / Serif / AnthropicMono Nerd Font Mono first with the outgoing families second, so a failed build degrades to yesterday's rendering rather than DejaVu. GTK font-name, document-font-name and monospace-font-name move together at the same sizes. sf-pro and sfmono-liga stay installed; the revert is this kitty block plus defaultFonts, together, and a switch.

fontTools reads the glyph header xMin/xMax as -12/1212 on every terminal face while a BoundsPen over the drawn contours gives -11/1213; both are the same Nerd box-art outline, and the assertion (x0 <= 0, x1 >= 1200) holds either way. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…one retry resolve/shape/geometry/a12 take the driver's uniform '<out> --src <dir>' form and --allow-partial for smoke builds (resolve.py declines to judge the four roles on a subset; shape.py skips absent faces). shape.py spawned ~45 kitty processes through one shared JSON path and once believed an empty result: each probe now writes its own file and an empty spawn is retried once.
