# Current Status > Source: https://health-assistant.io/docs/status # Project Status & Roadmap ## Current Status **Backend**: Running on http://localhost:8000 **Frontend**: Running on http://localhost:3000 **API Docs**: http://localhost:8000/docs ## Implementation Progress ### ✅ Completed #### Backend - FastAPI server with async support (Python 3.12+) - SQLAlchemy 2.0 ORM with PostgreSQL & Alembic migrations - JWT authentication with refresh tokens and presigned download tokens - FHIR resource models (Patient, Observation, DiagnosticReport, Medication) - Comprehensive Clinical Visit system (Examinations & Doctors) - AI OCR & NLP Pipeline (OpenAI Vision/LLM + spaCy) - Background task processing via Celery & Redis - Modular Notification Framework with Web Push (VAPID) support — replaced with the **unified notification system** (multi-source, multi-recipient, multi-channel, role-aware, real-time via WebSocket). See [NOTIFICATION_SYSTEM.md](NOTIFICATION_SYSTEM.md). - Unit converter service - Anomaly detector service (Reference range based) - Medication interactor service - Centralized semantic versioning manager - **Unified taxonomy & knowledge graph** — multi-kind `concepts` (one term can carry several domain tags via `concept_kind_tags`) + typed polymorphic `concept_edges`, replacing the scattered category tables. Searchable concept CRUD in the Catalogs workspace at `/catalogs?type=concept` (TaxonomyManager retired), REST API at `/concepts` + `/concept-edges`. See [TAXONOMY.md](TAXONOMY.md). - **Unified Catalog Registry + cross-domain knowledge graph** — a thin registry-driven `/catalogs` meta-layer gives every clinical catalog (anatomy, taxonomy, biomarkers, medications, allergies, **vaccines**) one CRUD/RBAC/search/FHIR/edge contract (`app/catalogs/`). `concept_edges` is the **single** link system: biomarker→anatomy `AFFECTS`, biomarker↔event-type `MONITORS`, biomarker→panel `MEMBER_OF`, specialty→organ `EXAMINES`, etc. Cross-catalog traversal at `GET /catalogs/{type}/{id}/relations` (recursive CTE); unified search at `GET /catalogs/search` + the global `/search` (both cover all registered catalogs). **Vaccinations (Phase 5)** are implemented end-to-end: `VaccineCatalog` + `PatientImmunization` tables, `/vaccines/*` REST CRUD, FHIR R4 `Immunization` facade resource, CVX-coded seeds. Phases 0–5 of `dev/plans/unified-catalog-architecture-2026-07-08.md` landed; diseases-as-concepts (Phase 6), the admin workspace (Phase 7), and LLM tools (Phase 8) landed. The legacy `biomarker_relationships` + `biomarker_event_correlations` tables are dropped (migrated to edges). - **Export & Import (backup) system** — FHIR R4B Bundle + BagIt-style ZIP exports at patient/group/system scope; validated imports with SHA256 manifest verification and cross-tenant id remapping (see [EXPORT_IMPORT.md](EXPORT_IMPORT.md)). Admin-only UI at `/settings/export-import` (export form, drag-and-drop restore, live job polling, download). - **Agentic AI Copilot + human-in-the-loop (HITL) proposals** — the chat assistant proposes clinical write actions (create a clinical event, add a biomarker to an examination, add a medication, define a new biomarker/medication in the catalog); the user reviews/edits and explicitly confirms before anything is saved (the AI never writes directly). After resolution, the agent gets an **auto-resume continuation turn** with structured outcomes fed back. **Parallel proposals** (multiple independent actions per turn) and a **Continue button** for partial resumes are supported. See [AI_SYSTEM.md §4.1](AI_SYSTEM.md). - **0.3.0 security & critical-fix pass** (see [CHANGELOG.md](../CHANGELOG.md)) — **all 29 Critical/High items resolved**: > **Note (2026-06-22):** A comprehensive re-audit performed after this pass catalogued **110 additional findings** (25 Critical / 32 High / 30 Medium / 23 Low) covering the FHIR R4 facade conformance, bidirectional FHIR interop, internal data pipeline, DB schema drift, and backend architecture. The **P0 stabilization batch (12 commits, 130+ regression tests)** below landed next, closing every Critical/High item in the audit's P0 tier. Remaining P1–P3 items are tracked in the local stabilization plan. - *First pass:* AI provider `api_key` encrypted at rest + masked in responses; scope checks on `/ai-config/providers/*` and `/models/*`; telemetry endpoints tenant-scoped; global exception handler no longer leaks `str(exc)` (now uses a `correlation_id`); `fetch-external-models` SSRF guard; `list_observations` actually applies its filters; `/fhir/Observation/history` no longer raises `TypeError`; `sync_active_integrations` correctly routes telemetry to TimescaleDB; `AIModel.__table_args__` typo fixed + migration `f1a2b3c4d5e6`; dead `processors/fhir_mapper.py` deleted; `from app.models import *` works again; telemetry service stubs replaced with real implementations. - *Second pass (P0 completion):* OHLC double-aggregation fixed (`AVG(AVG(col))` → single-level) + telemetry bucket whitelist; `relative_score` boundary logic fixed (strictly-interior = Normal, boundary defers to range check); Magic Fill date now uses `datetime.now()`; FHIR single-resource reads tenant-scoped at the service level (`get_observation`/`get_diagnostic_report`/`get_medication`/`delete_observation`); **prompt-injection guard** (`app/utils/prompt_guard.py`, 8 OWASP LLM01 patterns + `DEFENSE_PREAMBLE`); `print()` leaks in AI service replaced with `logger.debug`; **SVG sanitizer rewritten** (all event-handler quoting forms + `javascript:`/`vbscript:`/`data:text/html` URLs + `
