+# Investigation Report: Bpmf Zihi Kai Std
+
+## Source Data
+
+| Field | Value |
+|---|---|
+| Family Name | Bpmf Zihi Kai Std |
+| Designer | But Ko |
+| License | OFL |
+| Date Added | 2026-01-30 |
+| Repository URL | https://github.com/ButTaiwan/bpmfvs |
+| Commit Hash | `20f741c18bb917b63576293906c01e82ddfce032` |
+| Config YAML | None |
+| Status | missing_config |
+
+## How URL Found
+
+The repository URL was set in METADATA.pb during the original onboarding. Bpmf Zihi Kai Std was added via PR #10173 by Aaron Bell (`aaronbell`), merged 2026-02-11. The PR body describes it as a "New project" (unlike Huninn and Iansui which are "Based on existing GF fonts"). Same note about building in `aaronbell/bpmfvs` with planned transition to `ButTaiwan/bpmfvs`.
+
+All three Bpmf families share the same upstream repository.
+
+## How Commit Determined
+
+The commit hash `20f741c18bb917b63576293906c01e82ddfce032` was added by our automation (commit `9a14639f3`, 2026-02-25). This is the HEAD of `ButTaiwan/bpmfvs` from 2025-12-13.
+
+**Critical issue**: Same as the other Bpmf families. The fonts were built in `aaronbell/bpmfvs`, and the recorded commit predates the actual build by over a month.
+
+The onboarding timeline for Bpmf Zihi Kai Std is more complex, with multiple font binary updates:
+1. Initial onboarding: `f91754e81` (2026-01-30) "Adding Bpmf Zihi Kai Std"
+2. Formatting update: `44d5c78d8`
+3. METADATA update: `c27a727d9`
+4. First binary update: `8090ba2c9` (2026-01-30) "Update BpmfZihiKaiStd-Regular.ttf"
+5. Second binary update: `72cd1d1f6` (2026-02-09) "Updating with various fixes"
+6. Third binary update: `f55b8f2bb` (2026-02-09) "Update BpmfZihiKaiStd-Regular.ttf"
+7. Further fixes: `f56ed21ec` (copyright/license URLs), `26417436c` (newline), `3b5debf6e` (URL formatting)
+
+This family had the most font binary updates of the three Bpmf families (3 updates vs 1 each for Huninn and Iansui).
+
+## Config YAML Status
+
+**No config.yaml exists** and none can be created for gftools-builder.
+
+Same situation as all Bpmf families - custom Ruby-based build system (`make_font.rb`). The base font for Zihi Kai Std comes from `srcfonts/ZihiKaiStd.ttf` (source not documented in `upstream_sources.json`, suggesting it may be an original creation or sourced separately).
+
+## Verification
+
+- **Repository accessible**: Yes, both `ButTaiwan/bpmfvs` and `aaronbell/bpmfvs` are accessible
+- **Commit exists**: Yes, `20f741c` exists in both repos
+- **Commit is correct for current binary**: No - the current binary was built from a later commit in `aaronbell/bpmfvs` (likely from Feb 9, 2026)
+- **Local cache**: Neither repo is cached locally
+- **Source files**: Custom build system (Ruby-based), no standard font sources
+
+## Confidence Level
+
+**MEDIUM** - Same fundamental issues as the other Bpmf families. The repository URL is the canonical upstream but the fonts were built from Aaron Bell's fork. The commit hash is incorrect.
+
+## Open Questions
+
+1. **Which exact commit in aaronbell/bpmfvs produced the final binary?** The third update (`f55b8f2bb`, Feb 9, 2026) was the last binary change, so the build commit in the fork should be from around that time.
+2. **Where does the ZihiKaiStd base font come from?** Unlike Huninn (from justfont) and Iansui (from ButTaiwan/iansui), the Zihi Kai Std source font is not documented in `upstream_sources.json`.
+3. **Will the transition from aaronbell/bpmfvs to ButTaiwan/bpmfvs happen?** Until it does, the recorded commit hash will remain inaccurate.
+4. This family had the most updates of the three Bpmf families, suggesting it required more iteration to get right.
