Add two tests to TestRenderCostView exercising the untested branch A + B
combination where model_metrics={} and is_active=True:
- test_pure_active_session_no_metrics_shows_both_rows: verifies the
placeholder row and Since-last-shutdown row both appear
- test_pure_active_no_metrics_grand_total_includes_active_tokens: verifies
grand total output tokens includes active_output_tokens (1.5K)

Pull request overview
Adds regression coverage to render_cost_view for the previously untested case where a session is both active (is_active=True) and has no shutdown metrics (model_metrics={}), ensuring the placeholder session row and the “↳ Since last shutdown” row are exercised together.
Changes:
- Add a test asserting that an active session with empty
model_metricsrenders both the placeholder row and the since-last-shutdown row. - Add a test intended to ensure grand total output tokens include
active_output_tokensfor the no-metrics active session case.

Good catch — the original assertion "1.5K" in output would match the "↳ Since last shutdown" row and pass even if the Grand Total row were wrong.
Fixed by following the same pattern as test_resumed_session_no_double_count: stripping ANSI codes and using a regex to specifically target the Output Tokens column of the Grand Total row:
clean = re.sub(r"\x1b\[[0-9;]*m", "", output)
grand_match = re.search(
r"Grand Total\s*│[^│]*│[^│]*│[^│]*│[^│]*│\s*([\d.]+K?)\s*", clean
)
assert grand_match is not None, "Grand Total row not found"
assert grand_match.group(1) == "1.5K"All 383 tests pass, coverage remains at 96.65%.

Quality Gate: APPROVED ✅
Impact: LOW — Test-only changes (1 file, +38 lines), no production code modified.
Evaluation summary:
- Two well-structured tests added to
TestRenderCostView, covering the previously untestedmodel_metrics={}+is_active=Truebranch combination. - Tests follow existing patterns (using
SessionSummary,_capture_cost_view, consistent assertion style). - CI checks all pass (check, analyze, review, CodeQL).
- Coverage remains at 96.65%, well above the 80% threshold.
Note: The Copilot reviewer flagged that test_pure_active_no_metrics_grand_total_includes_active_tokens uses a broad "1.5K" in output assertion rather than targeting the Grand Total row specifically (as done in the neighboring test_resumed_session_no_double_count). This is a valid observation for a follow-up improvement but doesn't block this low-impact test addition.
Auto-approving for merge.
