From 09589b3bb23d2a30063c8843cd1e79365cb0359d Mon Sep 17 00:00:00 2001 From: goose Date: Sat, 4 Jul 2026 08:41:48 -0300 Subject: [PATCH 1/2] feat(backend): dose scheduling + health stats zero-knowledge Backend changes (frontend + tests follow in next commit): Dose scheduling: - New DoseSchedule struct (times_per_day + days_of_week) as a top-level plaintext field on Medication. Create/update requests accept it. - Revised get_adherence: computes scheduled_doses from the schedule over the period (days_of_week filtering), so missed doses are now reflected. Falls back to taken/total_logged when no schedule. Health stats zero-knowledge: - HealthStatistic model now uses opaque encrypted_data blob (like medications). Only recorded_at stays plaintext (filterable/sortable). - HealthStatResponse wire type. Handlers echo opaque blobs. - Removed the trends endpoint (server can't compute trends on ciphertext; frontend computes them client-side after decrypting). - Deleted the dead HealthData model (kept EncryptedField which it defined). Verified: backend 24 tests, 0 clippy warnings. --- backend/src/app.rs | 1 - backend/src/handlers/health_stats.rs | 242 +++++++++++---------------- backend/src/handlers/medications.rs | 86 ++++++++-- backend/src/handlers/mod.rs | 3 +- backend/src/models/health_data.rs | 26 +-- backend/src/models/health_stats.rs | 60 +++++-- backend/src/models/medication.rs | 48 ++++++ backend/tests/common/mod.rs | 4 + 8 files changed, 270 insertions(+), 200 deletions(-) diff --git a/backend/src/app.rs b/backend/src/app.rs index 0644947..fc19592 100644 --- a/backend/src/app.rs +++ b/backend/src/app.rs @@ -72,7 +72,6 @@ pub fn build_app(state: AppState) -> Router { // Health statistics management (Phase 2.7) .route("/api/health-stats", post(handlers::create_health_stat)) .route("/api/health-stats", get(handlers::list_health_stats)) - .route("/api/health-stats/trends", get(handlers::get_health_trends)) .route("/api/health-stats/:id", get(handlers::get_health_stat)) .route("/api/health-stats/:id", put(handlers::update_health_stat)) .route("/api/health-stats/:id", delete(handlers::delete_health_stat)) diff --git a/backend/src/handlers/health_stats.rs b/backend/src/handlers/health_stats.rs index 3db6a67..ca902cd 100644 --- a/backend/src/handlers/health_stats.rs +++ b/backend/src/handlers/health_stats.rs @@ -1,8 +1,9 @@ use crate::auth::jwt::Claims;

Health stats zero-knowledge: - HealthStatistic model now uses opaque encrypted_data blob (like medications). Only recorded_at stays plaintext. HealthStatResponse wire type. - Removed the trends endpoint (server can't compute on ciphertext); trends are now computed client-side in the health store after decryption. - Deleted the dead HealthData model (kept EncryptedField which it defined). - Frontend: health store decrypts on load + encrypts on write; trends computed client-side; HealthStats component uses domain form types. Verified: backend 24 tests 0 warnings; frontend build clean, 24 tests. --- .../src/components/health/HealthStats.tsx | 13 +- web/normogen-web/src/services/api.ts | 27 ++-- web/normogen-web/src/store/useStore.ts | 127 ++++++++++++++---- web/normogen-web/src/types/api.ts | 34 +++-- 4 files changed, 146 insertions(+), 55 deletions(-) diff --git a/web/normogen-web/src/components/health/HealthStats.tsx b/web/normogen-web/src/components/health/HealthStats.tsx index a76284d..f014765 100644 --- a/web/normogen-web/src/components/health/HealthStats.tsx +++ b/web/normogen-web/src/components/health/HealthStats.tsx @@ -37,7 +37,16 @@ import { } from 'recharts'; import { format } from 'date-fns'; import { useHealthStore } from '../../store/useStore'; -import { HealthStatType, type CreateHealthStatRequest, type TrendData } from '../../types/api'; +import { HealthStatType, type TrendData } from '../../types/api'; + +// Domain form type (decrypted fields the UI collects; the store encrypts them). +interface HealthFormData { + stat_type: HealthStatType; + value: number; + unit: string; + measured_at: string; + notes?: string; +} const STAT_TYPES = Object.values(HealthStatType); @@ -73,7 +82,7 @@ export const HealthStats: FC = () => { const [saving, setSaving] = useState(false); const [chartType, setChartType] = useState(HealthStatType.Weight); - const [form, setForm] = useState({ + const [form, setForm] = useState({ stat_type: HealthStatType.Weight, value: 0, unit: UNIT_DEFAULTS[HealthStatType.Weight], diff --git a/web/normogen-web/src/services/api.ts b/web/normogen-web/src/services/api.ts index eb8f6be..344586c 100644 --- a/web/normogen-web/src/services/api.ts +++ b/web/normogen-web/src/services/api.ts @@ -10,9 +10,7 @@ import { DrugInteraction, CheckInteractionRequest, CheckNewMedicationRequest, - HealthStat, CreateHealthStatRequest, - TrendData, ApiError, DoseLog, LogDoseRequest, @@ -20,6 +18,8 @@ import { MedicationWireResponse, AppointmentWireResponse, ProfileWireResponse, + HealthStatWireResponse, + UpdateHealthStatRequest, EncryptedFieldWire, CreateAppointmentRequest, UpdateAppointmentRequest, @@ -330,25 +330,25 @@ class ApiService { return response.data; } - // ---- Health Statistics ---- + // ---- Health Statistics (zero-knowledge: opaque encrypted blobs) ---- - async getHealthStats(): Promise { - const response = await this.client.get('/health-stats'); + async getHealthStats(): Promise { + const response = await this.client.get('/health-stats'); return response.data; } - async getHealthStat(id: string): Promise { - const response = await this.client.get(`/health-stats/${id}`); + async getHealthStat(id: string): Promise { + const response = await this.client.get(`/health-stats/${id}`); return response.data; } - async createHealthStat(data: CreateHealthStatRequest): Promise { - const response = await this.client.post('/health-stats', data); + async createHealthStat(data: CreateHealthStatRequest): Promise { + const response = await this.client.post('/health-stats', data); return response.data; } - async updateHealthStat(id: string, data: Partial): Promise { - const response = await this.client.put(`/health-stats/${id}`, data); + async updateHealthStat(id: string, data: UpdateHealthStatRequest): Promise { + const response = await this.client.put(`/health-stats/${id}`, data); return response.data; } @@ -356,11 +356,6 @@ class ApiService { await this.client.delete(`/health-stats/${id}`); } - async getHealthTrends(): Promise { - const response = await this.client.get('/health-stats/trends'); - return response.data; - } - // NOTE: lab-results endpoints are intentionally absent — the backend has no // /lab-results routes yet.
