Armata: reference the googlefonts/armata .glyphs source

Point METADATA.pb at the new googlefonts/armata repository (the FontForge SFD
source converted to Glyphs, building with gftools-builder3 + fontc) and
rewrite upstream_info.md to record the modernization.

+Source modernized 2026-07: the FontForge `.sfd` sources were converted to Glyphs (`.glyphs`) and now build with the Google Fonts Rust pipeline (gftools-builder3 + fontc). The repository, commit and config are recorded in the `source { }` block of METADATA.pb and are not duplicated here.
 
-## Data
+## Initial state
 
-| Field | Value |
-|-------|-------|
-| Repository URL | https://github.com/librefonts/armata |
-| Commit | `fbbc7c2575fe310df0450aaa721ee4e860b03a0e` |
-| Config YAML | — |
-| Branch | `master` |
-| Source types | sfd |
+The upstream repository at librefonts/armata shipped only FontForge sources (`src/Armata-Regular-TTF.sfd`) and had no config.yaml or Glyphs sources, so it could not build with the current Google Fonts pipeline. METADATA.pb recorded the repository and onboarding commit but no build configuration.
 
-## Methodology
+## Actions taken
 
-### Repository URL
-Discovered via google/fonts commit history, PR references, or GitHub search.
+The repository adopted the Unified Font Repository template. The FontForge source `src/Armata-Regular-TTF.sfd` was converted to Glyphs with babelfont-rs (upstream commit `219c0bb`), producing `sources/Armata-Regular.glyphs`, and a gftools-builder3 config was added. During conversion, the no-break space (U+00A0) was corrected to the expected advance width (683 units), and 22 glyphs were renamed to their production names. The superseded FontForge sources and legacy build cruft were then retired.
 
-### Commit Hash
-Used HEAD of upstream repository (latest commit at time of onboarding).
-- Commit date: 2014-10-17 13:29:34 +0300
-- Commit message: "update .travis.yml"
+## Final state
 
-### Config YAML
-Not applicable — upstream repo contains only FontForge .sfd sources, which are not compatible with gftools-builder.
+The repository builds `Armata-Regular.ttf` from `sources/Armata-Regular.glyphs` using gftools-builder3 and fontc. The `source { }` block in METADATA.pb points at the modernized repository, branch and config.
 
-## Evidence
+## Verification
 
-### METADATA.pb source block
-No source block present in METADATA.pb.
+The freshly built `Armata-Regular.ttf` was compared against the shipped Google Fonts binary on cmap coverage, vertical metrics, usWeightClass, fsSelection/macStyle, GSUB/GPOS feature sets, GDEF classes and advance widths. The verdict was FUNCTIONAL: the only difference was 22 glyphs renamed to their production names, with codepoint coverage unchanged. No blocking differences were found.
