+# WeirdUtils source provenance
+
+Audit date: 2026-08-31
+
+## Imported source history
+
+The repository is not marked by GitHub as a fork, but its imported Git history
+contains extensive source development authored by MarcelineVQ.
+
+The repository documentation points to the historical/source project at:
+
+- https://codeberg.org/MarcelineVQ/WeirdUtils
+
+## Dusk-92 GitHub maintenance boundary
+
+A comparison was made from the last inspected MarcelineVQ-authored baseline:
+
+- base: `41191ce9a5b50cf38fc48f138b8339ed17f9cae8`
+- pre-audit GitHub head:
+  `947056f1c22c4816f85038dfb78abe61c1e4133b`
+
+GitHub reports that the Dusk-92 head is four commits ahead of that baseline.
+
+Only two paths differ in that comparison:
+
+- `.github/workflows/release.yml`
+- `src/main.zig`
+
+The relevant later commits are:
+
+- `82dc02e2e78ca43496286c14a732a562d2448570`
+  — Add automated DLL release workflow
+- `f4cbacb7f9e91f99e7409b3aa48a61fe6d96d978`
+  — Fix DllMain return type for Zig 0.16
+- `c4d133887a9730e346d0654031cfeefb7a77e065`
+  — Run release build CI on main and support source refs
+- `947056f1c22c4816f85038dfb78abe61c1e4133b`
+  — Test full release packaging on main
+
+This makes the authorship boundary unusually clear: the GitHub maintenance
+layer should not be presented as authorship of the entire imported WeirdUtils
+source tree.
+
+## Third-party source boundaries
+
+Known third-party or reference-derived areas include:
+
+- `src/dpslog/WeirdDPSMate/` — DPSMate fork, GPL-3.0
+- `src/dpslog/WSBT/` — Mik/Athene material, license unresolved in this audit
+- `src/weirdperformance/libdeflate/` — libdeflate 1.25, MIT
+- `src/weirdperformance/timer_fix.zig` — ported from VanillaFixes, MIT
+- `src/ssemaths/math_sse.zig` — UnitXP_SP3 and libSiliconPatch references
+- external `zhook` build dependency — pinned in `build.zig.zon`
+
+See `THIRD_PARTY_NOTICES.md`.
+
+## Documentation-pass boundary
+
+No Zig, C, Lua, XML, build workflow, BLP, TGA, font, or other runtime asset is
+intended to be modified by the 2026-08-31 licensing/provenance pass.
+
+The final compare against the pre-audit head is the authoritative check for
+that statement.
