|---------------------------------------------------------------------|------|--------------|----------|----------------------------------------------------------------------------------------------------------------------|
| `server/services/appleHealthXml.js`                                 | 20   | Duplicate key in object literal (`hkquantitytypeidentifierheartratevariancessdnn` listed twice) | Warning | The second definition shadows the first — no bug since both map to the same value, but shows a copy-paste artifact |
| `client/src/components/meatspace/SleepCard.jsx`                     | 37   | Stage data unavailable at runtime | Warning | `getAppleHealthMetrics('sleep_analysis')` calls `/daily` endpoint which returns `{ date, value }` not `{ deep, rem, core, awake }`. Stacked bar will always show "Sleep stage breakdown not available". Hero avg works. |

**Duplicate HRV key (line 20):** Not a bug — both entries map to `'heart_rate_variability_sdnn'` — but is an artifact that could be cleaned up.

**Sleep stage data gap:** The stacked BarChart in SleepCard requires `{ deep, rem, core, awake }` fields, but `getDailyAggregates('sleep_analysis')` returns only `{ date, value }` (value = totalSleep). This means the stage proportion visualization will never render when using the current API call. The hero number (avg hours) will display correctly. This is a functional limitation that reduces the richness of HLT-05 but does not prevent the sleep card from displaying useful data. The fix would be to call `getAppleHealthSummary` for sleep or add a dedicated sleep stage endpoint.

### Human Verification Required

#### 1. Health tab visual rendering

**Test:** Navigate to `http://localhost:5555/meatspace/health`
**Expected:** Health tab appears in the tab bar (between Genome and Lifestyle). Four cards visible: Steps, Heart Rate, Sleep, HRV. Range selector buttons (7d/30d/90d/1y) visible. Clicking a range button changes displayed dates. Empty states show when no health data has been ingested. URL is deep-linkable (refreshing stays on Health tab).
**Why human:** Visual appearance, tab interaction, and deep-link behavior require browser.

#### 2. Import tab XML section

**Test:** Navigate to MeatSpace > Import tab (if accessible via tab, or `http://localhost:5555/meatspace/import`)
**Expected:** Apple Health XML Import section visible below TSV section, with a "Choose XML File" button. File picker accepts only `.xml` files. Instructions tell user to extract ZIP and upload export.xml.
**Why human:** UI rendering requires browser.

#### 3. JSON ingest end-to-end (with dedup)

**Test:** Run the following curl commands:
```bash
# First ingest
curl -X POST http://localhost:5554/api/health/ingest \
  -H 'Content-Type: application/json' \
  -d '{"data":{"metrics":[{"name":"step_count","units":"count","data":[{"date":"2024-01-15 08:30:00 -0800","qty":8432}]}]}}'

# Verify day file created
ls data/health/2024-01-15.json

# Dedup check — same record
curl -X POST http://localhost:5554/api/health/ingest \
  -H 'Content-Type: application/json' \
  -d '{"data":{"metrics":[{"name":"step_count","units":"count","data":[{"date":"2024-01-15 08:30:00 -0800","qty":8432}]}]}}'
```
**Expected:** First call returns `{"recordsIngested":1,"recordsSkipped":0,...}`. Day file `data/health/2024-01-15.json` exists. Second call returns `{"recordsIngested":0,"recordsSkipped":1,...}`.
**Why human:** Requires live server with write access to `data/health/`.

#### 4. Sleep stage stacked bar limitation

**Test:** After ingesting XML data with sleep records, check if the stacked bar chart shows sleep stages.
**Expected:** The hero average hours will display correctly. The stacked bar chart is likely to show "Sleep stage breakdown not available" because `getAppleHealthMetrics('sleep_analysis')` calls `/daily` which returns `{ date, value }` not `{ deep, rem, core, awake }`. Confirm whether this is acceptable or needs a fix.
**Why human:** Requires real sleep data and browser to observe rendering behavior.

### Notes on Implementation Quality

- **Timezone safety:** `extractDateStr()` uses `substring(0, 10)` not `Date()` — correct approach for Apple Health timestamps to avoid UTC shift.
- **Dedup key:** Uses full date string (not extracted date) — correctly distinguishes multiple same-day readings (e.g., multiple heart rate readings).
- **Schema future-proofing:** `healthDataPointSchema` and the `data` object use `.passthrough()` — handles future Health Auto Export app fields without breakage.
- **SAX error handling:** Error handler clears `_parser.error` and resumes — correctly handles Apple Health's occasionally malformed XML.
- **Post-parse aggregation:** Step and sleep aggregation happens outside SAX event loop — avoids complexity in callbacks.
- **Multer configuration:** `diskStorage` to `tmpdir()` with 2GB limit — prevents OOM on large files.
- **All 1192 server tests pass** — zero regressions.
- **Client builds cleanly** — 3332 modules compiled in 4.45s.
- **7 phase commits verified:** `7c2a592`, `200a0d2`, `2cd855f`, `8967415`, `a4b2d20`, `11cc0ea`, `81bd182`.
