 ## Source Repository
-- **URL**: No source block present
-- **Commit**: `N/A`
-- **Status**: absent
 
-## What Was Done
-The existing source metadata was reviewed. No `source` block was found in the METADATA.pb file; the family ships nine static TTF weight files (Thin through Black) with no upstream repository link recorded.

+## Description
+
+Myanmar script UI variant with tighter vertical metrics designed for Android system UI and web interfaces. Noto Sans Myanmar 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 This monorepo has since been superseded by the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 `442e7d208ce5...` 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
-- Designer: Google
-- Script: Myanmar (Mymr)
-- Category: SANS_SERIF
-- UI variant with static weights from Thin (100) to Black (900)
-- Covers Burmese, Mon, Shan, S'gaw Karen, Pwo Western Karen, and Khamti languages.
+
+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-myanmar-ui.yaml` in the `notofonts/myanmar` 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.
