Problem

The AI experiment summary numbers metrics as "inline metrics first, then shared metrics", ignoring primary_metrics_ordered_uuids / secondary_metrics_ordered_uuids. When the user has reordered metrics, "Metric 3" in the summary is a different metric than #3 in the app's metrics list.

Changes

Sort the combined metric list by the experiment's ordered uuids in ExperimentSummaryDataService before numbering. Metrics missing from the ordering keep their relative position at the end, and experiments without an ordering (null) keep the current behavior.

How did you test this code?

Extended test_fetch_experiment_data_combines_inline_and_saved_metrics with an ordering that puts the saved metric first and asserted the numbered names come out in that order. Without the fix, the inline metric stays first. Ran the full test_experiment_summary_tool.py suite (28 passed).

Autonomy: Human-driven (agent-assisted)

Claude Code found this while investigating why the AI summary referenced metrics not visible in the metrics list (#84316). Skills invoked: /wt, /writing-tests. Sibling PRs: #84316 (saved metric names), and a third for the summary metric cap.

Report-only. Patch coverage = changed backend lines covered vs origin/master. Sorted lowest first.
Known gaps: lines covered only by Temporal tests show as uncovered; core line numbers may drift if master changed the same file.

New commits pushed (delta classified non_trivial_delta) — stamphog approval dismissed; re-review running automatically.
