-## Methodology
+## Investigation Summary
 
-### Repository URL
-No upstream repository URL found.
+METADATA.pb for Akronim had no source block. A source block was added pointing to the librefonts mirror repository.
 
-### Commit Hash
-Commit hash unknown — could not be determined.
+## Source Analysis
 
-### Config YAML
-Not applicable — no upstream repository exists.
+The repository at https://github.com/librefonts/akronim 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.
 
-## Evidence
+**Available source types**: ttx (decompiled from binaries)
 
-### METADATA.pb source block
-No source block present in METADATA.pb.
+## Build Status
 
-### google/fonts history
-- Last font modification: `347b8a4d15b6`
-- Date: 2017-05-01 18:20:28 +0100
-- Subject: "hotfix-akronim: v1.002 added (#746)"
+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.
 
-## Confidence
+## Notes
 
-**High**: No upstream repository exists for this family.
+librefonts mirror with TTX sources. src/ has only METADATA_comments.txt and VERSIONS.txt.

+```
+
+## 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.
