v0.8.2
def8295

Korean infant/child reference data integration for Home Assistant.
Install via HACS → Custom repositories → https://github.com/redchupa/kr_baby_kit (Category: Integration).

Medical data integrity patch. Until v0.8.1 the integration accepted anything coerce-able to float() on measurement inputs — including NaN, Infinity, negative numbers, and stratospheric out-of-range values — and the LMS / BMI / weight-for-length math downstream then either produced nonsense percentiles or crashed deep inside the calculation. v0.8.2 closes that.

🛡️ Three layers of validation

Layer What it does Surfaces error as
record_measurement service _bounded_float() schema rejects type / NaN / Inf / range up front voluptuous Invalid → service-call response
Dashboard number entity HA's native min/max/step constrain the slider (unchanged behaviour) UI-level clamping
storage.async_append_measurement Re-validates regardless of caller ValueError with Korean message

The middle layer was already fine; the first and third are new in v0.8.2.

❌ Inputs now rejected (Korean error messages)

Bad input Message
None / 빈 값 키 값이 비어 있습니다.
"abc", "!!", "1,2", "" 키 값을 숫자로 읽지 못했습니다: 'abc'
True / False 키 값은 숫자여야 합니다 (참/거짓 X).
NaN 몸무게 값이 NaN 입니다.
±Infinity 몸무게 값이 무한대입니다.
height=-5 / weight=150 / head=10 등 범위 밖 키 값이 허용 범위를 벗어났습니다: -5.0 cm (허용: 30.0–200.0 cm).
date: "not-a-date" 측정일 형식이 올바르지 않습니다 (YYYY-MM-DD): 'not-a-date'

📏 Plausibility ranges

Wider than the KDCA 0–228 month chart (45–180 cm height, 3–80 kg weight, 33–58 cm head) so a slightly off entry still stores; clearly-mistyped values are caught up front.

항목 최소 최대
키 30.0 cm 200.0 cm
몸무게 1.0 kg 100.0 kg
머리둘레 25.0 cm 65.0 cm

✅ Tests

  • +33 unit tests in tests/test_validation.py covering every rejection class.
  • +4 storage-layer regression tests proving out-of-range / negative / non-numeric / NaN values are rejected at the persistence boundary, not only at the schema.
  • Total: 109 passed (pytest -q --ignore=tests/integration).

Upgrade notes

  • unique_id, sensor values, and on-disk records all unchanged.
  • Existing valid measurements continue to work without re-entry.
  • Service-call payloads that previously accidentally passed (e.g. weight: 0) now fail loudly with a Korean message — fix the payload and resubmit.
