Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The centralized install-dependency cache assumes each context is used for one tool request; if that invariant changes, dependency paths could be reused for the wrong request. Current call sites preserve the invariant, so the PR is mergeable with explicit owner follow-up; outdated method references are documentation-only and have no runtime impact.

dependency_contextis one unkeyedOnceCell, butdependency_context()accepts arequestparameter. The first caller initializes the cell. Any later caller that passes a differentToolRequestreceives the first request's context, with no error.Every construction site reviewed (
toolset_install.rsline 581,install_into.rsline 55,pipx.rsline 655) builds oneInstallContextper installed tool, andrun_postinstall_hookpassestv_exact.request, whichwith_locked()leaves unchanged. So the cache is correct today. The signature does not encode that invariant, so a future consumer can silently read dependency paths for the wrong tool.Prefer one of these:
- Store the request on
InstallContextand drop the parameter.- Add a
debug_assert!that the cached context belongs torequest.- Document the invariant on the field and the method.

3247-3277: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winUpdate the stale symbol name and consider reusing the declarations for the gate.
Two points in this block:
- Line 3251 refers to
install_dependency_toolset. This change removes that method. Rename the reference toinstall_dependency_contextso the comment matches the code.- Lines 3264-3273 recompute the dependency union with a second, independent
get_all_dependencies(true)call plus acore.dependscheck.install_dependency_declarationsalready produces exactly that union, and it additionally drops self-references and alias duplicates. The two can disagree: a tool that declares only itself setsdeclares_deps = trueand then resolves an empty context. The result is harmless today, but the duplicate logic is the kind this PR centralizes.Gate on the declarations rather than on the resolved context, so tools with no dependencies still skip resolution and keep the
