-## Source Data (METADATA.pb)
-
-```
-No source block
-```
-
-## Investigation
-
-The font is stored under `ofl/istokweb/` with an OFL license. The METADATA.pb has no `source` block at all.
-
-The font history in google/fonts shows:
-- `90abd17b4` — "Initial commit" — the font was present from the very beginning of the google/fonts repository (2015)
-
-The copyright states: "Copyright (c) 2008-2014, Andrey V. Panov (panov@canopus.iacp.dvo.ru), with Reserved Font Name Istok"

+| Commit | `f995ade61785c37629bed658e1898096ad934ec5` |
+| Confidence | High |
-The FONTLOG.txt in the google/fonts directory reveals:
-> The sources and truetype fonts are available at http://code.google.com/p/istok/
+## Source Types
-This points to **Google Code** (code.google.com/p/istok), which has been shut down since 2016. The font sources were originally hosted on Google Code, not GitHub.
+The repository contains Glyphs sources:
+- `sources/IstokWeb.glyphs` — Roman styles
+- `sources/IstokWeb-Italic.glyphs` — Italic styles
-The FONTLOG also describes the build requirements:
-> "You need fontforge (http://fontforge.sourceforge.net/), TTX/FontTools, xgridfit (http://xgridfit.sourceforge.net/ - version as of April 2010) and font-helpers (http://code.google.com/p/font-helpers/) in order to build the truetype fonts from the sources."
+## Build Compatibility
-The sources were in SFD format (FontForge native format) based on the build instructions mentioning fontforge and xgridfit. There is no known GitHub mirror of the original Google Code repository.
+No `config.yaml` is present in the upstream repository. The Glyphs sources could potentially be built with gftools-builder given an override config.
-No cached upstream repository was found in `upstream_repos/fontc_crater_cache/` for this family.
+## Investigation Notes
-The designer is Andrey V. Panov (email: panov@canopus.iacp.dvo.ru). The font supports Latin and Cyrillic scripts.
+This is Marc Foley's community maintenance repository for Istok Web. The original font was designed by Andrey V. Panov. The binary in google/fonts dates from the initial commit (2015-03-07). Marc Foley's repo contains modernized Glyphs sources suitable for future rebuilds.
-## Conclusion
+A source block was added to METADATA.pb pointing to this repository and commit.
-The original source repository was on Google Code (`http://code.google.com/p/istok/`) which has been shut down. No GitHub repository has been identified. The source format was SFD (FontForge) files, and there is likely no modern gftools-builder compatible `config.yaml` possible for this font.
+## Confidence: High
-Action needed: Check if there is a GitHub mirror of the Google Code repository, or if the font can be considered `no_config_possible` given its SFD source format and the Google Code origin.
+Marc Foley (m4rc1e) is a well-known Google Fonts contributor who maintains community repos for many fonts.
