📝 WalkthroughWalkthroughThe PR adds Rust dependency inventory and audit artifacts. It removes unused dependency declarations from workspace and crate manifests, including ChangesRust dependency cleanup
Priority: ⬇️ Low Estimated code review effort: 3 (Moderate) | ~25 minutes Change: Other Merge Risk: 🔵 Low · up to The audit documentation is ambiguous, and the census can omit a valid feature activation form.

Replace the corrupted dash separators.
The title and recommendation cells use ? where a dash separator is intended. This conflicts with the documented ? optional-owner marker.
Replace only the title separator and the separators after recommendation labels. Do not replace the optional-owner markers.
Also applies to: 11-11

Record qualified Cargo feature activators.
Cargo feature values can use cargo_alias/feature. When cargo_alias names an optional dependency, this form enables the dependency and its feature. The predicate omits this form from direct_feature_activators. The weak form cargo_alias?/feature must remain excluded.
Use the raw Cargo dependency key, not the normalized Rust alias.
Proposed fix
+ cargo_alias = dep.get("rename") or dep["name"]
feature_activators = [f for f, values in p["features"].items()
- if any(v in {"dep:" + (dep.get("rename") or dep["name"]),
- dep.get("rename") or dep["name"]} for v in values)]

‼️ 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.

Summary
Remove 22 unused Rust dependency declarations and the unused
similarworkspace template. The lockfile loses 15 external package versions without adding or upgrading packages; existing Tokio usage and library implementations stay in place.Changes
windows-core, ICU data feature edges, and crypto feature/version edges that need further investigation.The combined Windows normal/build dependency graph changes from 556 to 527 packages for default stdlib, 149 to 132 for minimal stdlib, and 98 to 91 for Compose. These are graph counts, not measured binary-size or speed gains. Dated audit snapshots deliberately preserve the pre-cleanup baseline.
Start with the audit and recommendations, then the per-library decisions.
