WalkthroughThe uv lockfile model now stores dependency names with optional versions and sources. Graph construction retains all packages with the same name and matches dependencies by name, version, and source. Optional dependency groups are included when edges are created. Existing fixtures use the new records, and a new test verifies graph resolution for multiple locked versions of numpy, pandas, and pytest. Priority: ⬇️ Low Merge Risk: 🟡 Moderate · up to Projects that use different locked versions of a package in production and development can receive incorrect dependency environment labels and transitive classification. Resolve the version-aware environment assignment before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

In `@src/Strategy/Python/Uv.hs`:
- Line 173: Update the prodDeps/devDeps construction used by newEnvs to retain
full UvLockPackageDependency records instead of mapping through
uvlockPackageDependencyName. When assigning environments, match packages using
the same name, version, and source criteria as resolveDependency, so different
locked variants receive only their correct environment and markDevDeps
propagates accurate results.
- Line 23: Update the Data.Foldable import in the Uv module to use the required
qualified full-module form, then qualify the existing fold, for_, and traverse_
call sites consistently while preserving their behavior.
- Line 125: Update the packagesByName assignment to replace the list
comprehension with an equivalent map-based expression, preserving
uvlockPackageName extraction and Map.fromListWith (<>) grouping behavior.

Use a qualified Data.Foldable import.
The mandatory Haskell import rule requires qualified imports with full module names. Qualify Data.Foldable and use the qualified names fold, for_, and traverse_ at their call sites.

Replace the list comprehension.
The project guidance says to avoid list comprehensions in Haskell. This changed expression can use map without changing its behavior.
Proposed change
- packagesByName = Map.fromListWith (<>) [(uvlockPackageName p, [p]) | p <- packages]
+ packagesByName = Map.fromListWith (<>) (map (\p -> (uvlockPackageName p, [p])) packages)📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Overview
If a uv.lock specified multiple versions of a package, we were dropping all but the last to occur in the lock file. This could result in orphaned dependencies if we ended up dropping the package that depended on it, causing it to erroneously appear as a direct dependency.
This change modifies the
packagesByNamemap to now maintain an array of packages with a given name, and when building the edges in the graph we will also check the version that we depend on to make sure the edge goes to the right version when multiple exist.Acceptance criteria
Edges are built correctly when the uv.lock specifies multiple versions of a package.
Testing plan
You can use https://github.com/jmschrei/memesuite-lite to test. Run
cabal run fossa -- analyze --output ./memesuite-liteand check thatpytzdoes not appear as a direct dependency, but rather as a dependency ofpip+pandas$2.3.3(which we previously dropped entirely).Risks
Highlight any areas that you're unsure of, want feedback on, or want reviewers to pay particular attention to.
Example: I'm not sure I did X correctly, can reviewers please double-check that for me?
