📝 WalkthroughWalkthroughThe PR removes the retired TP2/CP2 example and its tests. It makes the TP4/CP2 runbook canonical for CUDA and ROCm reproduction commands. It updates ROCm documentation to reference the shared runbook. ChangesVIME reproduction workflow
Priority: ⬇️ Low Estimated code review effort: 3 (Moderate) | ~20 minutes Change: Other Merge Risk: 🟡 Moderate · up to Operators may validate a nonexistent summary artifact and misunderstand the module-ablation workload, so the canonical reproduction instructions should be corrected before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Document the actual suite outputs and workload
run_supplement_suite.py runs eight module arms with eight rollouts, --n-samples-per-prompt 16, and global batch size 128. It creates per-arm directories containing manifest.json, run.log, run-validation.json, and COMPLETE on success, plus per-arm controller logs. It does not write $MODULE_ROOT/$MODULE_SUITE_ID.summary.json; checking that path therefore fails. Update the runbook to list these artifacts and the 16-sample workload.
