Tests cover profile aliases, fallback profiles, manifest failures, active-toolchain failures, and expanded installation scenarios. Rust documentation describes profile-based component restoration and customization. Rustup profile reconciliation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: ⚪ Minimal · up to Rust profile reconciliation now uses installed-manifest and host-specific component information, with explicit errors when active toolchain identity cannot be determined. The covered failure path avoids repeated ineffective reinstalls, leaving no concrete merge-blocking risk. Sequence Diagram(s)sequenceDiagram

Greptile SummaryThis review layer expands Rust host-triple recognition so component reconciliation correctly handles the
Confidence Score: 5/5This review layer appears safe to merge, with no actionable correctness or repository-rule violations identified. The new architecture entries flow through the existing host parser and component-matching logic, and the focused tests verify both newly supported RISC-V host triples. Important Files Changed

🌐 Web query:
Does "rustup component list --installed" print component names with the host target triple suffix?
💡 Result:
Yes, rustup component list --installed outputs component names that include a target triple suffix [1]. When a component is specific to a target (such as rust-std or cross-compiled versions of tools like rustc, cargo, or clippy), the output typically follows the format component-name-target-triple [1]. Note that this format is applied to components associated with a specific target, including those for the host machine [1]. Some components, like rust-src, may appear without a target triple suffix if they are not target-specific [1].

Handle an unavailable active-toolchain host
When rustup_active_toolchain fails, or returns a linked toolchain without a host triple, host is None. rustup_component_installed then accepts only exact component names. Because rustup component list --installed reports target-specific components with host suffixes, profile checks can report components as missing and reinstall the toolchain on each run.
Apply the clear-error handling used by the complete path, or match any host suffix when the host is unavailable.

An existing rustup toolchain does not regain missing complete-profile components when its profile is simply reapplied. This change reads release-specific membership from the installed manifest, resolves host-specific and renamed components, and passes missing profile requirements explicitly to rustup. Unusable metadata or failed identity discovery for an existing toolchain produces a clear error instead of an ineffective repair.
Depends on #12816, which depends on #12814. This PR targets main, so its GitHub diff includes those prerequisites. Review this layer only.
Profile membership and reverse renames follow rustup's manifest implementation. Custom sets remain configured with components and targets.
Validation: independent subagent review; lint passed on this layer; 32 Rust-plugin unit tests and reconciliation/custom-home/external-provider E2E tests passed on the combined stack. Regression coverage includes missing host components, reverse renames, failed active-toolchain discovery, and portable fixture edits.
