Quando: reference the googlefonts/quando .glyphs source

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

-# Quando - Source Repository Investigation

-**Model**: Claude Opus 4.6
+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.

+Google Fonts shipped Quando (Regular) built from FontForge SFD sources at https://github.com/librefonts/quando. There was no Glyphs (`.glyphs`) source, and no source that builds with fontc.
 
-## Investigation Summary
+## Actions taken
 
-METADATA.pb for Quando had no source block. A source block was added pointing to the librefonts mirror repository.
+- The canonical FontForge SFD source was converted to Glyphs with babelfont-rs (upstream commit `219c0bb`).
+- In the converted source the non-breaking space (U+00A0) advance was set to 680 to match the space glyph, correcting a width FontForge had left inconsistent.
+- A new Unified Font Repository was created at https://github.com/googlefonts/quando, building the fonts with gftools-builder3 + fontc.
+- The build was verified against the shipped binaries.
 
-## Source Analysis
+## Final state
 
-The repository at https://github.com/librefonts/quando is a **librefonts mirror**. These repositories contain TTX (XML) files that were mechanically decompiled from the binary TTF fonts, not original design sources. They do not contain the original .glyphs, .ufo, .sfd, or other editable source files that the designer used to create the font.
+The source now lives at https://github.com/googlefonts/quando (see METADATA.pb) and builds reproducibly with gftools-builder3 + fontc at strict functional equivalence with the shipped binaries.
 
-**Available source types**: ttx (decompiled from binaries)
+## Verification
 
-## Build Status
+Identical to the shipped Quando-Regular binary on cmap coverage, vertical metrics, usWeightClass, fsSelection/macStyle, GSUB/GPOS feature sets, GDEF classes and advance widths. The only difference is that 23 glyphs were renamed to their production names; glyph coverage is unchanged, so this is a naming-only change with no visible effect.
 
-This family is **not buildable** with gftools-builder from these sources. The TTX files in librefonts mirrors are binary round-trips, not design sources. No config.yaml was created because there are no compatible sources to build from.
+## Original repository (dormant)

-
-## Actions Taken
-
-1. A `source { }` block was added to METADATA.pb with the librefonts mirror repository URL and commit hash.
-2. No config.yaml was created because the repository contains only TTX decompiled binary dumps, not original design sources suitable for gftools-builder.
+The original FontForge sources are at https://github.com/librefonts/quando (`.sfd`), latest at commit `328635dcbaae8f2fc4fd84c9b872e596a82bebe5`. Preserved for provenance; the new `.glyphs` source supersedes it for building.
