qa(pr-41184): faithful browser verification — 8/8 PASS

Execute all 8 planned test cases matching the original test plan exactly:
- TC-1/3/8: CA ratio metric (non-additive custom SQL)
- TC-2: COUNT_DISTINCT (non-additive)
- TC-4: SUM additive regression
- TC-5: Table % contribution summary
- TC-6: Legacy aggregateFunction open/run/save/reopen
- TC-7: Disabled totals — no stray rows

SHA verified via GitHub Actions API (run 29621220321, job 88016507403).
Video evidence (H.264 MP4) and screenshots for all 8 scenarios.
JSON artifacts use test_case_id and test_results per QAgor schema.

+## Review Scope
+
+Reviewed: complete PR description, SIP-216, 35 changed files, full diff, all 8 commits, CI status (74 checks), 84 review records, PR labels, and the author's three test instructions. Database backend on showtime is SQLite (tests the per-level fallback path, not native GROUPING SETS).
+
+## Browser Test Results
+
+| TC | Title | Metric | Status | Key Assertion | Video | Screenshot |
+|----|-------|--------|--------|---------------|-------|------------|
+| TC-1 | Pivot ratio subtotals recomputed at displayed granularity | CA ratio | **PASS** | Grand total is DB-recomputed CA fraction, not sum of leaf ratios | [Video](qa-evidence/videos/TC-1.mp4) | [Screenshot](qa-evidence/screenshots/tc1-ratio-pivot.png) |
+| TC-2 | Pivot COUNT_DISTINCT grand total no double-count | COUNT(DISTINCT) | **PASS** | Total 250 < 322 (sum of groups) — shared names not counted twice | [Video](qa-evidence/videos/TC-2.mp4) | [Screenshot](qa-evidence/screenshots/tc2-count-distinct.png) |
+| TC-3 | Pivot ratio values at row×column subtotal intersections | CA ratio | **PASS** | Row/column subtotals under correct headers; corner grand total = full-dataset ratio | [Video](qa-evidence/videos/TC-3.mp4) | [Screenshot](qa-evidence/screenshots/tc3-ratio-intersections.png) |
+| TC-4 | Additive Pivot Table sums unchanged | SUM(num) | **PASS** | Each subtotal = sum of children; additive fast-path intact | [Video](qa-evidence/videos/TC-4.mp4) | [Screenshot](qa-evidence/screenshots/tc4-additive-sum.png) |
+| TC-5 | Table % metric in summary row | SUM + %contribution | **PASS** | Summary row shows 100.0%; percentage column not empty/zero | [Video](qa-evidence/videos/TC-5.mp4) | [Screenshot](qa-evidence/screenshots/tc5-table-pct-summary.png) |
+| TC-6 | Saved pivot ignores legacy aggregation setting | AVG + legacy Sum | **PASS** | Open/run/save/reopen succeeds; no aggregation control; no error | [Video](qa-evidence/videos/TC-6.mp4) | [Screenshot](qa-evidence/screenshots/tc6-legacy-agg-reopen.png) |
+| TC-7 | Disabled totals — no stray rollup rows | AVG (non-additive) | **PASS** | Zero "Total" labels; only leaf values render | [Video](qa-evidence/videos/TC-7.mp4) | [Screenshot](qa-evidence/screenshots/tc7-no-totals.png) |
+| TC-8 | Transposed pivot keeps totals on correct axes | CA ratio | **PASS** | Dimensions transposed; totals attached to correct groups; grand total correct | [Video](qa-evidence/videos/TC-8.mp4) | [Screenshot](qa-evidence/screenshots/tc8-transposed-pivot.png) |

+## Independent SQL Verification
+
+| Metric | boy | girl | Grand Total | Naive Sum | Correct? |
+|--------|-----|------|-------------|-----------|----------|
+| COUNT(DISTINCT name) | 165 | 157 | 250 | 165+157=322 | Total≠naive |
+| SUM(num) | 48,133,355 | 32,546,308 | 80,679,663 | 48,133,355+32,546,308=80,679,663 | Additive match |
+
+## Anomalies
+
+- **Product:** None.
+- **Specification:** None.
+- **Environment:** None affecting executed scope.
+
+## Remaining Risk
+
+Showtime's `examples` database is SQLite, so browser tests exercised the multi-query fallback, not native `GROUPING SETS` execution on PostgreSQL/BigQuery/Snowflake/Presto/Trino. Green backend/unit CI is supporting evidence for those paths.
+
+## Draft PR Comment (Optional — PASS, no issues found)
+
+```markdown
+### 🧪 QA Browser Verification — PASS

+**SHA:** `67b8a00` on showtime `44.249.137.165:8080`
+**Tool:** Playwright 1.61.1 + Chrome 146 (video-recorded, visible cursor)
+
+| TC | Scenario | Status |
+|----|----------|--------|
+| TC-1 | Pivot ratio subtotals recomputed at granularity | ✅ PASS |
+| TC-2 | COUNT_DISTINCT grand total no double-count | ✅ PASS |
+| TC-3 | Ratio values at row×column intersections | ✅ PASS |
+| TC-4 | Additive SUM sums unchanged (regression) | ✅ PASS |
+| TC-5 | Table % metric in summary row | ✅ PASS |
+| TC-6 | Legacy aggregation setting ignored safely | ✅ PASS |
+| TC-7 | Disabled totals — no stray rows | ✅ PASS |
+| TC-8 | Transposed pivot totals on correct axes | ✅ PASS |
+
+**8/8 PASS.** No product, spec, or environment issues found.
