+
+## How the Repository URL Was Found
+
+The repository URL `https://github.com/huertatipografica/betania-patmos` was present in the METADATA.pb file's source block from the initial onboarding. This is the same repository used by all Betania Patmos variants. The copyright string confirms: "Copyright 2024 The Betania Patmos Project Authors (https://github.com/huertatipografica/betania-patmos)".
+
+## How the Commit Hash Was Determined
+
+The commit hash `08c83ac9540b0b2bf86ddf6b632651142f31a93c` was present in the METADATA.pb source block from the initial onboarding. The onboarding commit (`c26502dc7`) by Emma Marichal (2026-01-23) explicitly states: "Taken from the upstream repo https://github.com/huertatipografica/betania-patmos at commit https://github.com/huertatipografica/betania-patmos/commit/08c83ac9540b0b2bf86ddf6b632651142f31a93c".
+
+This is the same commit hash used for all Betania Patmos variants. The commit is a merge of PR #4 ("build fonts") dated 2026-01-15, and Betania Patmos GDL was onboarded 8 days later on 2026-01-23. The timeline is consistent - all variants were onboarded from the same upstream snapshot.
+
+## Config YAML Status
+
+- **Path**: `sources/config.yaml`
+- **Exists at recorded commit**: Yes, verified via GitHub API
+- **Contents**: Same config as the base Betania Patmos family - references `betania-patmos.glyphs` as the source file
+- **Note**: The METADATA.pb source block does NOT include a `config_yaml` field. The tracking file records the discovered path but it has not been added to METADATA.pb yet.
+- **No override config.yaml** exists in the google/fonts family directory
+
+## Verification
+
+1. Commit hash `08c83ac9540b0b2bf86ddf6b632651142f31a93c` verified to exist via GitHub API
+2. Font file `fonts/ttf/BetaniaPatmosGDL-Regular.ttf` confirmed present at that commit
+3. `sources/config.yaml` confirmed present at that commit
+4. Repository URL confirmed accessible
+5. The `branch: "main"` field is correct
+6. The `display_name: "Betania Patmos Guideline"` in METADATA.pb indicates GDL stands for "Guideline" (different from the "Guide Line" variant which has ruled lines for handwriting practice)
+
+## Confidence Level
+
+**High** - Full provenance documented in the onboarding commit message. Same commit hash as the other Betania Patmos variants, all from the same upstream snapshot. All file paths verified.
+
+## Open Questions
+
+1. The METADATA.pb source block is missing the `config_yaml` field. Should it be added?
+2. The display_name "Betania Patmos Guideline" clarifies the GDL abbreviation but may cause confusion with the separate "Betania Patmos Guide Line" family.
