+## How URL Found
+
+The repository URL `https://github.com/cadsondemak/Charmonman` was already present in the METADATA.pb `source` block. It is also referenced in the copyright strings of the font files and in the original onboarding commit message: "Taken from the upstream repo https://github.com/cadsondemak/Charmonman at commit https://github.com/cadsondemak/Charmonman/commit/8590fc4aaefe8ccf9ec0abeff7f66b6bc1a83503".
+
+## How Commit Determined
+
+The commit `8590fc4aaefe8ccf9ec0abeff7f66b6bc1a83503` is explicitly referenced in the original onboarding commit message (`fc91fcc12`): "charmonman: v1.000 added. Taken from the upstream repo https://github.com/cadsondemak/Charmonman at commit https://github.com/cadsondemak/Charmonman/commit/8590fc4aaefe8ccf9ec0abeff7f66b6bc1a83503".
+
+This commit is also the HEAD of the upstream repository (confirmed: `git rev-parse HEAD` matches). The commit is dated 2018-08-22, the same day as the google/fonts onboarding, and represents "Merge pull request #4 from m4rc1e/gf-mastering" -- Marc Foley's work to prepare the font for Google Fonts.
+
+The commit hash was later added to the METADATA.pb source block by commit `4fd9e2392` ("Add source metadata to 125 METADATA.pb files").
+
+## Config YAML Status
+
+An override `config.yaml` exists in the google/fonts family directory at `ofl/charmonman/config.yaml`. It specifies:
+- Source: `source/Charmonman.glyphs`
+
+The upstream repo contains a `source/Charmonman.glyphs` file, confirming the override config is valid.
+
+## Verification
+
+- **Repository URL**: Verified -- the upstream repo is cached at `upstream_repos/fontc_crater_cache/cadsondemak/Charmonman`.
+- **Commit**: Verified as HEAD of master in the upstream repo. Explicitly referenced in the original onboarding commit message. The commit date (2018-08-22) matches the google/fonts onboarding date.
+- **Source files**: Upstream contains `source/Charmonman.glyphs` as referenced in the override config.
+- **Override config**: Confirmed present and valid.
+
+## Confidence Level
+
+**Very High** -- The commit hash is explicitly stated in the original onboarding commit message, confirmed as HEAD of upstream, and the dates align perfectly. This is one of the most well-documented onboarding references.
+
+## Open Questions
