From b6caa98a98758e391515b58aeb17641e239cc17d Mon Sep 17 00:00:00 2001 From: RohanExploit <178623867+RohanExploit@users.noreply.github.com> Date: Sat, 16 May 2026 10:47:12 +0000 Subject: [PATCH 1/4] feat: Add Civic Eye UI and fix camera fallback - Exposed the Civic Eye (Safety Checker) feature button on the Home view's Auxiliary Systems section. - Added voice commands to trigger Civic Eye ("civic eye" or "civic-eye") via FloatingButtonsManager. - Implemented robust `try-catch` fallback mechanisms for `navigator.mediaDevices.getUserMedia()` in `EmotionDetector`, `CivicEyeDetector`, and `PotholeDetector` to default to any available camera if specific `facingMode` constraints fail. - Fixed backend test suite by resolving async testing requirements (`pytest-asyncio` integration). - Applied code formatting using `black` on backend. --- backend/__main__.py | 14 +- backend/adaptive_weights.py | 36 +- backend/ai_factory.py | 1 + backend/ai_interfaces.py | 17 +- backend/ai_service.py | 52 +- backend/bot.py | 69 ++- backend/cache.py | 66 ++- backend/civic_intelligence.py | 109 ++-- backend/closure_service.py | 187 ++++--- backend/config.py | 99 ++-- backend/database.py | 10 +- backend/dependencies.py | 14 +- backend/escalation_engine.py | 118 ++-- backend/exceptions.py | 141 +++-- backend/flooding_detection.py | 1 + backend/garbage_detection.py | 24 +- backend/gemini_services.py | 27 +- backend/gemini_summary.py | 31 +- backend/geofencing_service.py | 150 +++--- backend/grievance_classifier.py | 6 +- backend/grievance_service.py | 166 ++++-- backend/hf_api_service.py | 411 ++++++++++---- backend/hf_service.py | 137 +++-- backend/hf_text_service.py | 17 +- backend/hf_text_services.py | 1 + backend/infrastructure_detection.py | 1 + backend/init_admin.py | 18 +- backend/init_db.py | 388 ++++++++++--- backend/init_grievance_system.py | 78 ++- backend/local_ml_service.py | 183 ++++--- backend/maharashtra_locator.py | 48 +- backend/main.py | 51 +- backend/main_fixed.py | 306 +++++++---- backend/ml/train_grievance.py | 24 +- backend/mock_services.py | 8 +- backend/models.py | 200 +++++-- backend/pothole_detection.py | 66 ++- backend/priority_engine.py | 72 ++- backend/rag_service.py | 64 ++- backend/resolution_proof_service.py | 228 +++++--- backend/routers/admin.py | 31 +- backend/routers/analysis.py | 5 +- backend/routers/auth.py | 47 +- backend/routers/detection.py | 94 +++- backend/routers/field_officer.py | 348 +++++++----- backend/routers/grievances.py | 475 ++++++++++------ backend/routers/hf.py | 3 + backend/routers/issues.py | 444 +++++++++------ backend/routers/resolution_proof.py | 126 +++-- backend/routers/utility.py | 117 ++-- backend/routers/voice.py | 260 +++++---- backend/routing_service.py | 74 ++- backend/scheduler.py | 10 +- backend/schemas.py | 510 ++++++++++++++---- backend/sla_config_service.py | 80 ++- backend/spatial_utils.py | 55 +- backend/tasks.py | 102 ++-- backend/test_ai_services.py | 3 +- backend/test_grievance_escalation.py | 18 +- backend/tests/benchmark_cache.py | 4 +- backend/tests/benchmark_closure_status.py | 97 +++- backend/tests/benchmark_serialization.py | 15 +- backend/tests/benchmark_urgency.py | 4 +- .../tests/benchmark_urgency_unoptimized.py | 5 +- backend/tests/test_cache_perf.py | 9 +- backend/tests/test_cache_unit.py | 11 +- backend/tests/test_civic_intelligence.py | 115 ++-- backend/tests/test_detection_bytes.py | 47 +- backend/tests/test_new_detectors.py | 61 ++- backend/tests/test_new_features.py | 66 ++- backend/tests/test_priority_engine.py | 43 +- backend/tests/test_rag_service.py | 2 + backend/tests/test_schemas.py | 71 ++- backend/tests/test_severity.py | 26 +- backend/tests/test_spatial_performance.py | 20 +- backend/tests/test_spatial_utils.py | 36 +- backend/tests/test_utils.py | 16 +- backend/trend_analyzer.py | 101 +++- backend/unified_detection_service.py | 146 ++--- backend/utils.py | 78 +-- backend/vandalism_detection.py | 1 + backend/voice_service.py | 341 ++++++------ frontend/src/CivicEyeDetector.jsx | 13 +- frontend/src/EmotionDetector.jsx | 17 +- frontend/src/PotholeDetector.jsx | 17 +- .../src/components/FloatingButtonsManager.jsx | 1 + frontend/src/views/Home.jsx | 15 + 87 files changed, 5112 insertions(+), 2707 deletions(-) diff --git a/backend/__main__.py b/backend/__main__.py index 34419439..8fca7976 100644 --- a/backend/__main__.py +++ b/backend/__main__.py @@ -1,12 +1,13 @@ """ Entry point for running the backend as a module. -This allows running: +This allows running: - From root: python -m backend - From backend: python -m __main__ This will start the FastAPI application with uvicorn, which includes the Telegram bot via the lifespan context manager.
