+### Changed
+- Bumped the pinned `uv` version from `0.11.29` to `0.12.1` in `pyproject.toml`
+  and every `astral-sh/setup-uv` workflow step (`ci.yml`, `create-release.yml`,
+  `publish.yml`) to match the version the central org coverage-evidence
+  pipeline trusts and hash-verifies. The prior pin was structurally
+  incompatible with that pipeline's fixed trusted `uv`: `uv export --frozen`
+  refuses to run whenever the invoking `uv`'s version does not match a
+  project's own `[tool.uv] required-version`, so every coverage-evidence run
+  against this repository failed regardless of the PR's own diff
+  (`ContextualWisdomLab/.github#1234`). `uv.lock` regenerated byte-identical
+  under `0.12.1` (RankWeave has zero runtime dependencies); full suite
+  re-verified at 661 passed, 100% statement/branch coverage, ruff clean.
