Add first-class qualitative lab findings (positive / negative / borderline serology) alongside the existing numeric path. A LabResult is now EITHER a numeric reading (value + unit, optional reference bounds) OR a qualitative one (valueText, e.g. "negativ"), never both, never neither. - schema: make `value` nullable, add `value_text`; migration 0181 is additive (DROP NOT NULL + ADD COLUMN), every existing numeric row is untouched. - validation: numeric-XOR-qualitative refine on create + update; unit/bounds apply to the numeric path only; valueText capped at 120 chars. The single resource PUT rejects a cross-type edit. - serialise: carry valueText through both DTOs; a qualitative row reports the neutral `unknown` range verdict (no number to classify). - FHIR: a qualitative result emits valueCodeableConcept — SNOMED qualifier value for confidently-known terms (Negative 260385009, Positive 10828004, Not detected 260415000, Detected 260373001), text-only for borderline / grenzwertig and any unrecognised term. The raw text always rides .text. - UI: a numeric/qualitative toggle in the lab form; list, history, detail, chart, sparkline, and the doctor-report PDF all render qualitative readings as their text and never plot or divide on a null value. - i18n: new labs.form keys across all six locales. - openapi: response carries a nullable value + valueText; regenerated.

-- v1.18.9 — qualitative lab results (positive/negative/borderline serology).
|
|
--
|
|
-- A LabResult was numeric-only (`value` NOT NULL). Qualitative findings
|
|
-- ("Hepatitis Bs-Antigen: negativ") have no number to store. This migration is
|
|
-- ADDITIVE and preserves every existing numeric row:
|
|
--
|
|
-- 1. `value` becomes nullable so a qualitative row can omit it. Existing rows
|
|
-- keep their numeric value untouched (DROP NOT NULL never rewrites data).
|
|
-- 2. `value_text` is added (nullable) to hold the qualitative result string.
|
|
--
|
|
-- A row is QUANTITATIVE when `value IS NOT NULL`, QUALITATIVE when
|
|
-- `value_text IS NOT NULL`. The application layer enforces the exclusive-or.
