**NOT APPROVED — 3 Important findings**

1. **Planned/missed/cancelled medication rows can appear as medication administrations**
   - `scripts/health/health_dashboard_v4.py:641-644`
   - The Arzttermin “Medikation” cards use unfiltered `medication_admins` and omit `event_type`. A `planned`, `cancelled`, or `missed` row therefore looks like an actual dose.
   - **Fix:** Build these cards from `administered_medications`, or create a visibly separate planning section that displays the event status explicitly. Add generated-HTML tests containing all positive and negative event types.
   - The actual symptom-chart overlay and main timeline correctly use the strict `administered`/`verabreicht` allowlist at lines 652 and 680–683.

2. **Nutrition missingness is rendered as numeric zero**
   - `scripts/health/health_dashboard_v4.py:526-565`, especially `526-534`, `556-558`, and `563-565`
   - Additional occurrences: `659`, `715`
   - Nullable kcal, macros, histamine load, amount, and nutrient fields use expressions such as `value or 0`. Missing observations consequently appear as measured `0`, violating missing-as-unknown.
   - **Fix:** Render nullable values as `unbekannt`/`—`; only display numeric zero when zero was explicitly observed. Histamine labels/load should also remain unknown when classification completeness is insufficient. Add a synthetic dashboard test with explicit zero and SQL `NULL` side by side.

3. **Freshness parsing accepts incomplete ISO datetimes**
   - `scripts/health/health_dashboard_v4.py:109-120`
   - The broad `"T" in text` branch delegates to permissive `datetime.fromisoformat()`. Synthetic probes showed both `2026-01-09T12` and `2026-01-09T12:34` classified as `aktuell`.
   - This is not the required strict, fail-closed handling of complete supported date/datetime formats.
   - **Fix:** Require a full-match allowlist for exact `YYYY-MM-DD` and complete datetime forms, including a defined timezone policy. Reject reduced-precision timestamps as `unbekannt`. Retain the current future classification as `prüfen`.

**Other reviewed properties**

- Apple stable canonical data day and import/process timestamp are separately presented at lines 738–745.
- Future freshness dates are not clamped to age zero; they render as `prüfen`.
- Legacy `compute_nutrition_features()` is not called by the current renderer, and synthetic generation left `nutrition_daily_features` empty. However, dead legacy scoring helpers and `makeBarChart` remain in the file/generated script; removal would reduce regression risk.
- Personal-tolerance visible copy is neutral and explicitly says it is not a food-safety classification.
- N-of-1 warning is direct, adjacent to the tracker, noncausal, and includes no-therapy/no-challenge guidance plus clinician alignment.
- Complete symptom totals preserve gaps and distinguish explicit zero from absent/partial days.
