`uv check` currently resolves its standalone `ty` executable from uv’s built-in compatible range, even when the project’s locked development dependencies select a different version or source. When `uv.lock` contains an applicable `ty` package, `uv check` now runs that exact locked package. It first looks in the project’s `dev` group, then falls back to a direct runtime dependency. With `--no-sync` (or when `ty` is excluded by the selected dependency groups), uv materializes only the locked `ty` subgraph into a cached environment without modifying the project environment. The precedence order for ty version selection is now: - the `TY` executable override - an explicit `--ty-version` - the applicable `ty` package from `uv.lock` (if any) - uv’s default constrained range when the lock contains no applicable `ty` development dependency This work was split into several focused pull requests, which are now dependencies of this PR: - [[#19907](https://github.com/astral-sh/uv/pull/19907)](https://github.com/astral-sh/uv/pull/19907) adds the locked-subgraph materialization and cached-installation primitives this PR uses. This PR is stacked on it. - [[#19909](https://github.com/astral-sh/uv/pull/19909)](https://github.com/astral-sh/uv/pull/19909) makes `uv check --no-sync` perform the normal lock operation while skipping environment synchronization. - [[#19892](https://github.com/astral-sh/uv/pull/19892)](https://github.com/astral-sh/uv/pull/19892) adds the hidden `uv check --show-version` flag used to verify version selection. - [[#19913](https://github.com/astral-sh/uv/pull/19913)](https://github.com/astral-sh/uv/pull/19913) moves related `uv check` tests from live PyPI dependencies to deterministic Packse fixtures.

Replace live-PyPI dependencies in
uv checkproject lock and sync tests with existing Packse fixtures. The tests now pass the local index explicitly and use deterministic package metadata instead ofanyio,iniconfig, and unnecessary CLI--exclude-newercutoffs.This also moves declared-dependency and isolated-project coverage into the
test-r2shard. TheTYexecutable precedence test remainstest-pypigated because it requires installing a realtyexecutable; existingTYprecedence and ty download tests are otherwise unchanged.
