 ### Fixed
 - **`variants/<v>/skills/<name>/` now carries `references/` and sibling files**,
   not just `SKILL.md`. Previously only `SKILL.md` was injected, silently breaking
   skills that read `references/*.md` at runtime. Backward compatible — the
   copy-into-`variants/` path keeps working, now correctly.

+### CI
+- **`pip-audit` now ignores the disputed pyjwt advisory PYSEC-2025-183 / CVE-2025-45768.**
+  Upstream rejects the classification — alleged weak-key behavior is the calling
+  application's responsibility, and pyjwt 2.12.1 has no fix release. pyjwt enters
+  our tree only transitively via `harbor → supabase-auth / mcp`, so we cannot
+  upgrade past it. `pip-audit --strict` still hard-fails on every other CVE. ([#52])
