| + | # Feature Matrix — Implemented vs Pending |
| + | |
| + | > [!info] Legend |
| + | > ✅ implemented & wired · 🟡 partial/scaffolded · ⏳ pending (PRD/roadmap) · ❌ removed/not started |
| + | |
| + | ## Core Features (PRD §5.1) |
| + | |
| + | | Feature | PRD Priority | Status | Evidence / Notes | |
| + | |---|---|---|---| |
| + | | Classroom scene narration | P0 | 🟡 | Capture/UI and Edge invocation exist, but successful client response is fixed text; hardware gesture delivery is unverified | |
| + | | Whiteboard & text reading (OCR) | P0 | 🟡 | Read prompt exists; no OCR engine, hardware double-tap callback, or returned-model-text path | |
| + | | Classroom/slides mode + notes PDF | P0 | 🟡 | Bluetooth service has a branch/PDF helper; active Scene UI does not route its Classroom action to that branch | |
| + | | Emotion detection | P0 | 🟡 | Prompt and face-name injection exist; Edge response is discarded and no hardware left-double-tap callback was found | |
| + | | Person identification | P0 | 🟡 | FaceNet compares against Supabase-fetched CSV embeddings; not local-only, model failures are unsafe, and fallback answer is fixed text | |
| + | | Academic content filter | P0 | 🟡 | Enforced via prompts (academic tone, constrained outputs); no separate filter layer yet | |
| + | | Academic Mode (level vocabulary) | P0 | ✅ | Toggle on Home; appends academic-level instruction to prompts | |
| + | | Student voice persona | P1 | 🟡 | Four presentation companions + local selection; no distinct voice/prompt mapping. Active Scene helper retains legacy child filtering | |
| + | | Activity detection | P1 | 🟡 | Covered by scene/classroom prompts; no dedicated mode | |
| + | | Object identification | P1 | 🟡 | Via chat ("Be My Eyes") free-form questions | |
| + | | Hallway & navigation alerts | P1 | 🟡 | `HallwayNavigationService` (≤12-word cues) exists; not surfaced in UI | |
| + | | VLM switcher | P1 | 🟡 | `VisionService.VlmProvider` enum (moondream/llava/GPT4V) in legacy dashboard; not in student UI | |
| + | | Teacher dashboard | P1 | 🟡 | PIN-gated face registration + `SupabaseDashboardRepository` + FERPA audit logs; no web portal | |
| + | | Parent dashboard | P1 | ⏳ | Schema/planning only | |
| + | | Offline mode | P2 | ⏳ | PRD roadmap; `sessions.offline_mode` column exists; context mesh notes "Offline mode: Gemma 3" struck through | |
| + | | Multi-language support | P2 | 🟡 | Sarvam translate/TTS for Indic languages in speak path; UI English-only | |
| + | | Weekly learning summary | P2 | ⏳ | Today's Story covers daily; weekly report not built | |
| + | |
| + | ## Interaction Features |
| + | |
| + | | Feature | Status | Notes | |
| + | |---|---|---| |
| + | | Glasses gestures (single/double tap, hold) | 🟡 | Callable handlers exist; no DAT gesture callback registration was found | |
| + | | One-shot voice commands (long-press) | 🟡 | Android speech service exists; no verified DAT trigger or source broadcaster for documented commands | |
| + | | "Hey Netra" wake word | ❌ | WakeWordService removed per user request; receiver hooks remain; PRD/JIRA AC still open | |
| + | | AI chat w/ image+video ("Be My Eyes") | 🟡 | Chat/media UI and Edge invocation exist, but client replaces responses with fixed success text | |
| + | | Lecture notes + AI summary | 🟡 | Device transcript and Edge invocation exist; summary response is fixed success text | |
| + | | Today's Story recap | ✅ | Timeline + "Read My Day Out Loud" | |
| + | | Emergency SOS | 🟡 | EmergencyAlertManager service only; no trigger, GPS/summaries TODO | |
| + | | Smart auto-capture / battery saver | 🟡 | SmartCaptureController (2s/10s intervals); toggle in settings; scene-change detection TODO | |
| + | | Recess/playground social | 🟡 | RecessSocialService exists; not surfaced in UI | |
| + | |
| + | ## Platform / Infra |
| + | |
| + | | Item | Status | Notes | |
| + | |---|---|---| |
| + | | Supabase auth (email, OTP, Google) | ✅ | gotrue-kt; deep links `threenetra://` | |
| + | | Firebase → Supabase migration | ✅ | "Phase 5 complete, Firebase disconnected" (Mayukh log, Jun 2026) | |
| + | | AWS SAM AI gateway | 🟡 | Routes are implemented but `AwsBackendService` is unreferenced by production app code; deployment workflow omits its OpenAI parameter | |
| + | | Encrypted local face embeddings | 🟡 | Utility exists but is unreferenced; active enrollment/matching uses Supabase | |
| + | | Realtime settings sync | ✅ | Realtime channel on `student_settings` | |
| + | | GitHub Actions APK build | ✅ | Pushes to `prod` build and upload a debug APK; no test/lint/release signing gate | |
| + | | Face recognition w/ local embeddings (README roadmap) | ✅ | Done — README item stale | |
| + | | Real-time shared classroom materials | ⏳ | README roadmap | |
| + | | E2E testing coverage | ⏳ | README roadmap; unit/instrumented scaffolding only | |
| + | | Teacher/parent web portals, My School Subjects | ⏳ | PRD screens not built | |
| + | | iOS companion app | ⏳ | PRD mentions iOS/Android; Android only today | |
| + | |
| + | ## Roadmap (Context Mesh + PRD) |
| + | |
| + | **Meta glass app roadmap:** OCR, face recognition, emotion, campus navigation, multilingual output, dashboards, and offline support are roadmap/document claims. This audit does **not** promote them to delivered: the active AI client returns fixed success text, local-only face storage is unused, and hardware behavior is untested. |
| + | |
| + | **PRD phases:** Treat PRD phases and checkmarks as planning evidence. Source supports partial UI/service scaffolding, not verified delivery of an end-to-end VLM, OCR, gesture, dashboard, or safety-navigation release. |
| + | |
| + | **Q2 epics (org):** Revisit PRD · Redesign UI/UX wireframes · Redesign website (Fable5 Vercel) |
