-## Summary
+## Description
 
-Noto Sans Sinhala UI was listed in Google Fonts as a UI variant of Noto Sans Sinhala, published as a variable font with `wdth` (62.5–100) and `wght` (100–900) axes, covering the Sinhala script (Sinh) and supporting Sinhala, Pali, and Sanskrit. The copyright notice references Google Inc. (2016), indicating it predates the per-script GitHub repository structure used by the current Noto project. No repository URL, commit, or config_yaml was recorded in METADATA.pb. The font was added to Google Fonts on 2020-11-19.
+Sinhala script UI variant with tighter vertical metrics designed for Android system UI and web interfaces. Noto Sans Sinhala UI is a UI variant of the corresponding Noto Sans family. UI variants use tighter vertical metrics (smaller ascender/descender values) than the standard versions, designed for Android system UI and web interfaces where vertical space is constrained.
+
+## Upstream Details
+
+The source repository is `googlefonts/noto-fonts`, the pre-2022 Noto monorepo that contained
+pre-built binary fonts for all Noto families. This monorepo has since been superseded by the
+per-script repositories under the `notofonts/` GitHub organization, which contain sources and
+build from source using modern tooling. However, the binaries currently served on Google Fonts
+for this family were built from the old monorepo, not the newer per-script repos.
+
+The commit `da23fbffb845...` was verified by blob-hash comparison: the font binary
+blob hashes at this commit in the monorepo match the blobs added in the google/fonts
+onboarding PR #2823.
+
+## Notes
+
+UI variant. Dec 25 2020 batch.
+
+## Confidence
+
+**HIGH** (blob-hash verified against onboarding PR)
+
+## Build Configuration (Override)
+
+An override `config.yaml` has been created in the google/fonts family directory, copied from `sources/config-sans-sinhala.yaml` in the `notofonts/sinhala` repository (the current per-script Noto repo). **Important caveat**: this config references the current notofonts/ per-script repo sources, which may produce a newer version than the binary currently shipped in google/fonts. The shipped binary was built from the older `googlefonts/noto-fonts` monorepo using a different build pipeline. This override config serves as a starting point for reproducible build attempts but is not expected to produce a byte-identical match.
