[/diagnosing-bugs] The fix is correct, but the why is missing — future readers will not know that Run.Turns can be stale/zero specifically in the cached-summary rendering path.

    processedRun.Run.Turns = summary.Metrics.Turns
}

Without this context, the next developer may remove it as apparently defensive dead code.

@copilot please address this.

[/tdd] Consider also testing the edge case where both Run.Turns and Metrics.Turns are zero — the current fix silently leaves turns as 0 in that scenario, which would still produce a false turns_decrease in comparison. A dedicated test makes the invariant explicit.

💡 Suggested test 
func TestProcessedRunFromSummaryBothTurnsZero(t *testing.T) {
    summary := &RunSummary{
        Run:     WorkflowRun{DatabaseID: 789, Turns: 0},
        Metrics: LogMetrics{Turns: 0},
    }

    processed := processedRunFromSummary(summary, "/tmp/run-output")

    // Both are zero — no backfill occurs, and turns should remain 0.
    assert.Equal(t, 0, processed.Run.Turns, "turns should remain zero when neither Run.Turns nor Metrics.Turns is available")
}

Documents the known limitation: if a run genuinely has zero turns and Metrics.Turns is also zero, the delta will still reflect 0.

@copilot please address this.

Missing test for the both-zeros edge case (Run.Turns == 0, Metrics.Turns == 0). The two new tests cover backfill (zero→non-zero) and preservation (non-zero→non-zero). Neither exercises the path where Metrics.Turns == 0 too — meaning the guard summary.Metrics.Turns > 0 is never exercised as false. A future regression that drops the > 0 check and unconditionally writes summary.Metrics.Turns back to processedRun.Run.Turns would not be caught by the current suite.

💡 Suggested test 
func TestProcessedRunFromSummaryBothTurnsZero(t *testing.T) {
    summary := &RunSummary{
        Run:     WorkflowRun{DatabaseID: 789, Turns: 0},
        Metrics: LogMetrics{Turns: 0},
    }

    processed := processedRunFromSummary(summary, "/tmp/run-output")

    // Neither field has data; turns should remain 0, not be set to Metrics.Turns.
    assert.Equal(t, 0, processed.Run.Turns, "run turns should remain 0 when both Run.Turns and Metrics.Turns are 0")
}

Added TestProcessedRunFromSummaryBothTurnsZero and also applied the same Run.Turns backfill from Metrics.Turns inside computeRunMetricsDiff (audit_diff.go) so audit diff is fixed for old cached summaries too — see 3d0db57.


assert.Equal(t, 7, processed.Run.Turns, "existing run turns should not be overwritten by summary metrics")
}

func TestProcessedRunFromSummaryBothTurnsZero(t *testing.T) {
summary := &RunSummary{
Run: WorkflowRun{DatabaseID: 789, Turns: 0},
Metrics: LogMetrics{Turns: 0},
}

processed := processedRunFromSummary(summary, "/tmp/run-output")

assert.Equal(t, 0, processed.Run.Turns, "run turns should remain zero when neither Run.Turns nor Metrics.Turns is available")
