Summary

Follow-up to upstream PR #3712, targeting its feature branch. Unavailable or partial GPU discovery could select the 7.2.1 overlay and replace an existing ROCm 10 installation during package repair.

Changes

• Require complete Windows inventory before repair, preserving advisory reporting behavior.
• Reject automatic changes between installed ROCm release families and conflicting active Torch/shared-SDK metadata before downloads or package mutation. Healthy reuse and fresh/same-family setup remain available, including a supported discrete GPU alongside an advisory iGPU.
• Resolve test modules canonically at test time and document the repair boundary. Package pins, native verification, DLL selection and BF16 safeguards are unchanged.

Type

• 🐛 Bug fix
• ✨ New feature
• ♻️ Refactor
• 📝 Documentation
• 🧪 Tests
• 🔧 CI / Build
• 🚀 Release prep

Testing

• Windows: 176 passed, 1 skipped across seven focused modules, offline with initially empty HF/Torch caches. The skip is an existing Linux sysfs case unavailable on Windows.
• Changelog fragment policy: 10 passed. The existing changelog.d/3712.added.md entry includes the repair safeguard and retains Dutch credit, so its reference stays correct when absorbed into upstream feat(windows-rocm): add verified RDNA 2 Torch and HIP CTranslate2 speech debpalash/VoiceStudio#3712.
• Fail-before controls cover incomplete inventory, well-formed unmapped PCI IDs and conflicting active package families; repaired cases assert zero download/install calls. A separate inert control demonstrates canonical module resolution despite a stale parent-package alias.
• No ROCm 10 installation, real GPU/model inference, independent wheel-hash verification or full CI/smoke-matrix validation was performed. This does not certify a hardware/runtime combination.

Checklist

• I've tested this locally
• Every non-exempt human commit author has signed the CLA
• I've updated relevant documentation
• User-visible change: I updated the existing upstream changelog.d/3712.added.md fragment
• No local machine paths, logs, or personal env details in this PR
• Maintained version files are unchanged; no version bump
• The regression fixture still loads green on the macOS/Windows/Linux smoke-matrix CI job

Release cadence

This draft targets feat/windows-rocm-rdna2, not main. Upstream integration, hardware qualification and release/publication remain separate from this focused fix.
